Honda Ridgeline 2024 — Reported problems

My auto stop engine device would not restart at an intersection and it left me stranded . The truck would not move, and I tried repeatedly to get the truck moving. This has happened several times this year since December 2025. Bravo Honda, Victoria, Texas told me they were not sure what caused the problem, but they said they charged the battery and felt as if this would resolve the issue. The next time I had an issue Bravo Honda replaced the battery and I was told that was the issue. Now this time Bravo Honda, Victoria , Texas has escalated the issue to Honda tech. They have had my truck 2 days and no resolution as yet, although they believe the starter is faulty and needs replacing. This is very dangerous as I have been left stranded in heavy traffic. I feel the mechanic maybe guessing at what is wrong with the truck. The last incident happened on 09/17/2026.

2024 Honda Ridgeline, VIN [XXX], approximately 21,000 miles. The vehicle has repeatedly failed to restart in traffic after the Auto Idle Stop system automatically shut off the engine. Failures occurred XXX. During one occurrence, I was nearly rear-ended when the vehicle failed to restart as traffic began moving. The vehicle also intermittently cranks abnormally slowly when hot. The starter will crank, pause, then crank noticeably slower. I can intermittently reproduce the fail to start problem by driving until the vehicle is hot, shutting it off, and immediately restarting it. I have two videos of this condition. Honda replaced the battery, but the problem continues. The dealer reports that the battery, alternator, and starter pass diagnostic testing. I provided video documenting the abnormal slow cranking and failure to start, but no repair has been made. My primary safety concern is that Auto Idle Stop automatically shuts off the engine while stopped in active traffic, but the vehicle may then fail to restart, leaving it disabled in a traffic lane. The vehicle has already experienced this failure three times. NHTSA is currently investigating Auto Start/Stop no-restart complaints involving 2020–2025 Honda Ridgelines under EA25-004.

I am reporting a recurring Auto Idle Stop no-restart and starting-system failure in a 2024 Honda Ridgeline. At approximately 35,072 miles, while stopped at a traffic light with Auto Idle Stop engaged, the engine shut off but failed to restart when the brake pedal was released. The vehicle remained disabled in the intersection until it was manually restarted, creating a risk of a collision. An authorized Honda dealer found both positive and negative battery terminals loose, tightened them, reported that the battery passed a load test, found no diagnostic trouble codes, and returned the vehicle. The battery had already been replaced at approximately 30,238 miles after a slow-start complaint and a failed battery test. The condition recurred at approximately 42,563 miles. After the engine shut off at a light, the vehicle displayed an orange “P” and “System Problem Detected - Shift to Park,” went into Neutral, and required a manual restart before Drive could be restored. The dealer later reported that the replacement battery tested at approximately 197 CCA against its 650 CCA rating, but no root cause for the rapid deterioration or the shutdown/no-restart condition has been identified. The vehicle now intermittently cranks slowly and appears strained while starting. No permanent repair has been completed. The vehicle is available for inspection. The condition creates a safety risk because the vehicle can fail to restart or move from an intersection and may enter Neutral unexpectedly.

VEHICLE SHUTS DOWN WHILE IN IDLE AT STOP LIGHT

While stopped at a red light, the auto on/off feature engaged and the engine shut off. Upon release of the brake, the engine failed to restart.

When stopped at a stop light the auto start feature sometimes - more often than not- fails to start back and the truck is stuck at the intersection. After putting it in park it will start after several tries. My dealership tells me there is nothing wrong with it even though it’s still under warranty. This has happened over 10 times to me

Receiving pop up faults on instrument panel. ie battery low voltage, adaptive cruise sys problem, road departure mitigation sys problem, Sys problem detected shift to park, to start engine brake and push start, idle stop engine will not restart all of these issue donot throw codes to the main ECM or BCM so dealer can't trace the problem. This has been going on since march 2025

My vehicle is currently sitting at a Honda dealership with a broken crankshaft counterweight and seized bearing. The engine needs to be replaced but Honda has refused to conduct the dealership warranty and blame shift it to a cracked oil pan that had happened in November of last year that was quickly addressed. Since then I have gone to [XXX] and back to [XXX] showing the vehicle was fine and operating. It is to my understanding that my 2024 Ridgeline has a 3.5L J-Series V6 engine. The NHTSA is actively investigating over 1.4 million Honda V6 engines for this exact connecting rod bearing seizure defect. I feel it is wrong for the dealership to pin a known defect on something unrelated and have insurance pay and avoid conducting the warranty repair. My vehicle is sitting at 39,000 miles and I was on a normal commute to work when the incident occurred and still covered under factory warranty.

Truck fails to restart after the auto idle shut off. The battery goes dead and I cannot restart. This has happened several times so I now turn the Idle Off feature off. However, since it does not stay off permanently, if I forget to turn if off the truck may fail to restart. It has left me stuck at intersections unable to restart on several occasions.

After coming to a stop and the idle stop feature engages, the vehicle does not automatically restart. I am presented with a message that says "system problem detected. shift to park". After shifting to park, I am presented with another message that says ""to continue to drive, depress the brake pedal and push switch." I then have to completely shut off the engine by pushing the "stop button". Then, I have to do a full restart before the vehicle starts again. This has happened 5 times in the last month. Here is a video of one incident - [XXX].[XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2024 Honda Ridgeline. The contact stated that while stopping at a red light, the Auto START feature failed to restart the vehicle, and the vehicle started rolling backwards. The brake pedal was depressed, and the PUSH to START button was depressed, and the vehicle was restarted. The dealer was contacted; however, the vehicle was not yet diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 34,200.

The contact owns a 2024 Honda Ridgeline. The contact stated that while attempting to start the vehicle with the Push-To-Start feature, the vehicle failed to start. No warning light was illuminated. Additionally, while idling in traffic, the vehicle lost automotive power and failed to accelerate as intended while the accelerator pedal was depressed. The vehicle was restarted as a temporary fix. Upon further inspection, the contact became aware of an abnormal electrical burning odor entering the cabin of the vehicle. The vehicle was taken to a local dealer, where it was diagnosed; however, no cause for the failure was found. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 35,000.

I OWN A 2024 HONDA RIDGELINE TRAILSPORT. THE AUTOMATIC IDLE IS CONTINUOUSLY DRAINING THE BATTERY, MAKING IT HARD FOR THE TRUCK TO START. I HAVE PURCHASED 2 BATTERIES SINCE MAY 2024, WHEN I PURCHASED THE TRUCK. IT APPEARS THAT THERE IS SOMETHING WRONG WITH THE AUTOMATIC IDLE ON THE TRUCK, BUT HONDA TELLS ME THERE IS NOTHING WRONG. WHEN ACTIVATED, THE AUTOMATIC IDLE WILL SHUT DOWN THE VEHICLE IN TRAFFIC, CAUSING A VERY DANGEROUS SITUATION BECAUSE THE BATTERY DOES NOT HAVE ENOUGH POWER TO START THE VEHICLE WHENIT STALLS.

Windows and moon roof on 2024 Honda Ridgeline opens when parked. Lock button on Key fob is supposed to be pressed twice to activate this feature but opens when fob is on desk or in my pocket. No damage yet but could cause problems for theft or rain damage if parked outside when unattended

2024 Honda Ridgeline. Brakes stick or slow to release. Feels like brakes are dragging. Delayed acceleration. This is unsafe. Dealer has had vehicle 7+ days total across 2 repair attempts from March 25th 2026 thru April 1st 2026 and again April 29th 2026 and dealership still has the vehicle. Has not been able to fix the issue. Honda issued Dealer Message on August 7, 2025 stating "American Honda Motor Co.,Inc. is searching for certain 2023-2025 Odysseys, Passports, and Ridgelines with a customer complaint of the brakes sticking. Vehicle purchased April 1st 2024 and has 12,700 miles. Currently at dealership for 2nd attempt. this is a known safety defect Honda is actively investigating. Sticking brakes crash risk. Delayed acceleration. Feeling of brakes dragging. Ongoing intermittent issue. I have been offered a loaner vehicle on both occasions.

My husband was driving the vehicle to school with the sunroof shade closed. Without any impact or anything hitting the sunroof, it shattered. I tried filing a warranty claim with Honda, and they denied the claim without requesting any evidence.

The auto high beam is widely known to be so bad it behaves the opposite of how it should. It frequently blinds other drivers when it should not turn high beams on, often blinding them in the last few seconds before passing, causing a dangerous situation, not to mention the possibility of drivers thinking it was done on purpose maliciously. This has led to near road rage experiences. The high beams also rarely turn on when they should but at least there is a manual override.

LIGHTED RUNNING BOARD LIGHTS CONTINUOUSLY QUIT WORKING. HONDA HAS A TECHNICAL SERVICE BULLETIN ISSUED BUT THIS IS A KNOWN PROBLEM.

My Honda CMBS system has false warnings from cars coming from the other lane and road markers setting off the system. I had numerous incidents where the steering wheel shakes and a brake warning illuminates with no possibility of an accident. After this warning the car would automatically brake to stop you. I have taken this vehicle to the dealer twice they said it is perfect. Honda knows this system is defective. In the owners manual they describe all the false warnings. I have experienced every one in the manual. I have begged the dealer and Honda company that I believe the camera mounted in front of the mirror is too sensitive and defective but they won’t replace it. The camera also controls the automatic bright lights and they won’t stay on for more than 6 seconds. I contend that this camera also sets off the emergency braking due to oncoming lights or reflective lights in the road. There is a class action lawsuit over this system up to a 2023 Ridgeline. All I want is a new camera and the Cmbs system to work correctly but Honda won’t repair it. They deny it is defective. They claim they can’t duplicate it. Of course they drive it once and say it’s fine. Please make Honda replace this faulty system

The Automatic High Beam system does not work properly and are very inconsistent. When enabled, the high beams often turn on for a brief moment then turn off. Sometimes this occurs when there is a road sign reflection or a light on a home on the side of the road. When the system is enabled, the high beams often fluctuate on and off even when there is no oncoming traffic. What is worse is that the high beams sometimes remain on with oncoming traffic, blinding the oncoming driver. I am reporting that this has occurred ever since I purchased the vehicle in 2024. The dealer indicated this is a known problem and that Honda doesn't seem to be doing anything about it.

The Auto High Beams (AHB) fail to work correctly. When set to on, they will come on for maybe 3-4 seconds then turn off, and maybe repeat the next time. The bigger issue is they fail to turn off many times when approaching oncoming traffic. The feature is dangerous by not turning on when they should and not turning off when they should. This is a widespread problem reported by many. The Honda dealer said they adjusted the sensitivity of the AHB when in fact there is no such adjustment. There is clearly something wrong with the implementation on the Ridgeline as other same year Honda models (we have a 2924 CRV) do NOT have this problem.

Vehicle has stalled after being stopped at red light. Does not occur all the time. Only when in idle mode.

Auto Start/Stop Malfunction. On two occasions the Auto start/stop has shut the engine off at a stop light and after releasing the brake the vehicle went completely dead. Dashboard/radio and all electronics dead. After multiple attempts the vehicle finally restarted. Now the normal start is sluggish like a low battery. Battery was replaced under warranty and check out multiple times by the dealership with them not able to find any issues.

The vehicle’s engine and powertrain management system repeatedly fails with multiple DTC's triggering a full-system cascade of safety-critical warnings and automatic power-limiting. The issue affects the engine, transmission, emissions, AWD, brake system, stability assist, steering assist, ABS/VSA, hill-start assist. The vehicle is fully available for inspection upon request. During each failure, the vehicle abruptly enters reduced-power “limp mode” without warning—resulting in loss of engine power, disabled AWD, and disables all safety/stability systems. These events have occurred in normal traffic, including at red lights and in intersections, creating a risk of rear-end collisions, inability to accelerate, and loss of vehicle control. I transport an autistic child, making reliability and predictable vehicle behavior critical to passenger safety as well. The problem has been reproduced and documented by multiple authorized Honda dealerships. The vehicle has now undergone 13 repair attempts in the first 14 months of ownership, across 6 different Honda dealerships. All have been unable to diagnose or permanently repair the defect. The vehicle has been repeatedly inspected by Honda technicians, who escalated the issue to Honda Tech Line. Tech Line documents (dated 10/1/25) show that no aftermarket modifications exist and that the failure is verified but intermittent and ongoing. Warning Lamps / Symptoms: Each failure event triggers a full dashboard sweep including: – AWD System Problem – Emissions System Problem – Transmission System Problem – Power Steering System Problem – Vehicle Stability Assist Problem – Hill Start Assist Problem – Brake System Warning – Road Departure Mitigation Problem – Blind Spot Information System Problem There is a federal lawsuit filed filed in Oregon District court case 6:25-cv-02142-AP

Between 1,000-1,400 rpm there is a lower end engine knock.sounds like a bearing.

I was driving alone on US-HWY 45 in Chunchula, AL......I heard the loudest noise ever sounded like a high power rifle blast in my ear then I was showered with glass. The sunroof exploded. I had a police report written, I literally thought I had been shot at. There was only myself and one other very small vehicle way ahead of me. No trees hanging over the road or anything.

While idling at a traffic light,2 systems shut down: Adaptive Cruise Control & Road Departure Mitigation System. Also the BRAKE SYSTEM light came on, but the brakes continued to work.

Using the Automatic High Beam system, the high beam may come on even if a car is coming toward me. Sometimes, the high beam will not transition to low beam until the incoming car is real close to me. The incoming car would put his high beam on to warn me. As well, the high bean can randomly transition to low beam for no reason. And a second after, come back to high beam. Really dangerous. I had other cars with this system and never had that kind of problems.

The contact owns a 2024 Honda Ridgeline. The contact stated that while driving 50 MPH, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact stated that several unknown warning lights were illuminated. In addition, the brakes were independently activated. The contact stated that the vehicle failed to accelerate above 30 MPH. The vehicle was taken to the dealer; however, the contact was not informed of the diagnostic results. The contact was informed that unknown repairs were being performed. In addition, the contact stated that the failure had occurred more than thirty times. The contact stated that with 137 miles on the vehicle, the vehicle was taken to the dealer, where the failure was diagnosed as a failed brake switch, and the warning lights were reset. The failure reoccurred. The contact stated that the failure was persistent. The contact requested that the dealer buy back the vehicle, and the request was denied. In addition, the contact stated that he feared driving the vehicle. The manufacturer was not made aware of the failure. The failure mileage was 137.

The contact owns a 2024 Honda Ridgeline. The contact stated that while driving at 55 MPH, there was an extremely loud banging noise detected, and the sunroof exploded upward and outward without warning or impact. The driver and his wife sustained a piercing, ringing sound in the ears, but medical attention was not provided. The local dealer was contacted, where it was diagnosed, but they were unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The approximate failure mileage was 12,246.

Auto-dimming headlights do not work properly, not always dimming for oncoming traffic, and/or randomly switching between high and low beams without cause. This blinds and confuses oncoming traffic.

The auto High beam function on this vehicle is absolutely useless. It dims when it should be on. It dims needlessly for highway markers and road signs. The constant on and off of the high beams on a dark road with no other cars is dangerous. This system on the ridgeline is dangerous. I have the system on other cars and it works almost perfectly but not in this vehicle.

Experiencing numerous false error warnings from Collision Mitigation Braking System (CMBS) when meeting oncoming vehicles on straight or slightly curving two lane roads. I have taken my vehicle three times to be serviced for this specific reason and a Blind Spot Information System error. The BSI appears to be repaired now but the false CMBS warnings still have not been repaired. The most recent incidents listed below occurred today after picking up the truck from the BSI repair.

I am filing this complaint regarding the OEM General Grabber A/T tires (date code 1424) that came with my brand new 2024 Honda Ridgeline, purchased in June 2024. At approximately 16,000 miles, I noticed significant dry rotting and cracking between the treads on all four tires. This was observed right before a planned long-distance trip, raising serious safety concerns. I maintain proper tire pressure and take excellent care of my vehicle, and I live in Vermont where the climate is harsh but not extreme enough to justify this kind of premature deterioration. The dealer referred me to Honda’s 1-800 number, who then directed me to Continental, the parent company of General. Continental opened a case and instructed me to visit a Continental dealer, who confirmed the dry rot but said they need to pull the tires to send them back to Continental for inspection before they decide whether to approve the warranty claim. Meanwhile, I am expected to purchase a new set of tires upfront. This process is not only burdensome but also concerning given the potential safety risk of these tires. Tires with only 16k miles should not be deteriorating like this, and I believe other owners should be aware of the issue. Please investigate the integrity and safety of these tires, as the premature dry rot could pose a serious hazard to drivers.

See attached document for complaint.

While sitting at a stop light at an extremely busy intersection, After pressing the Auto Idle Off button in trying to keep the air conditioner running, my vehicle just completely shut down like it had a completely dead battery. I couldn’t even turn on my hazard lights. The vehicle was completely dead. After pressing the on/off button several times, power to the vehicle was restored and I was able to restart the vehicle. It reminded me of when a computer glitches and reboots on its own. By happening at an extremely busy intersection, I felt like my safety and the safety of others may have been in jeopardy if other vehicles would have made aggressive maneuvers to get around my inoperable vehicle.

Manual driver’s seat height adjustment slowly reverts to a lower height position without touching the manual mechanism. This is a daily occurrence. The vehicle has not yet been inspected by the dealer or any other independent source. This problem began occurring shortly after purchasing the vehicle, or was unnoticed until then. An internet source that claimed to be a mechanic for my brand identified the problem requiring a new seat base, as the mechanism is built into that seat base.

The automatic engine stop/start system is a safety hazard. On multiple occasions with two different drivers (husband and wife owners), the engine has stopped just as the accelerator is pressed after waiting for traffic to clear at a stop sign or while waiting to enter a street from a driveway or parking lot. The delay when expecting the vehicle to accelerate has nearly caused accident(s) several times. Drivers are forced to switch off the automatic stop/start system every time the vehicle is driven since it defaults to active and it is not safe to use. The system should be permanently disabled or at least programmed to be disabled as default when engine is started. This issue was reported to the local Honda dealer during the first routine service--owners were told that nothing could be done by the dealer. The service advisor suggested that we contact manufacturer or NHTSA directly. The incident date and mileage were entered below for yesterday since that was the latest event. It has happened numerous times since the vehicle was purchased in July 2024.

The contact owns a 2024 Honda Ridgeline. The contact stated that while operating the vehicle with the auto high beam feature activated, the auto high beam feature malfunctioned, causing the high beam lights to turn off and on independently. The contact stated that the high beam lights were illuminated for more the 8 seconds before deactivating. The contact stated that the failure had created a visibility hazard for the driver. The vehicle was taken to the local dealer who diagnosed that the failure was due to a faulty multifunction camera. The multifunction camera was replaced but the failure persisted. The manufacturer was notified of the failure and determined that the multifunction camera had operated as intended. The failure mileage was 100. The VIN was not available.

The auto-dimming bright lights are too sensitive, going on & off so quickly it creates a hazard to the driver & on-coming traffic. It is almost like a strobe light. These trucks have had this very same problem for years. Please force a fix.
