Toyota Highlander 2014 — Reported problems

Transmission failing beginning at 60,000 miles. Safety issue because car shudders and refuses to accelerate at seemingly random times. My mechanic said this is a known issue and recommended transmission flushing. We've been doing this for six years at lesser and lesser intervals before the problem reappears. Our local Toyota dealership said they've never heard of the problem but it is reported on numerous automotive forums.

Component: Latches/Locks — Power Door Lock Actuator I am the original owner of a 2014 Toyota Highlander AWD, currently with 88,000 miles on it. I have experienced six power door lock actuator failures on this vehicle. All replacements were OEM Toyota parts, and all repairs were paid out of pocket. Failure history: - 01/12/2019 — driver rear (original part) - 02/27/2019 — driver front (original part) - 12/07/2019 — passenger rear (original part) - 06/09/2023 — passenger front (original part) - 08/08/2025 — driver rear (OEM replacement, 6 yr 7 mo service life) - 08/30/2026 — driver front currently failing (OEM replacement, 7 yr 6 mo service life) All four original actuators failed between years 5 and 9 of the vehicle's life. Two OEM replacements have since failed on a comparable schedule. This is a consistent wear-out pattern across every door on the vehicle, not isolated part failure. The higher-cycle driver-side doors have now failed twice each. Current condition: the driver front door intermittently does not lock when commanded by the key fob or by the interior lock switch. The failure is silent — there is no chime, warning, or indication that the door did not secure. The driver has no way to know the door is unlatched without physically checking it. Safety concern: an unsecured door can open during vehicle operation, and reduces occupant protection in a side impact or rollover because the latch is not engaged. Because the failure is intermittent and gives no warning, a driver can reasonably believe the vehicle is locked when it is not. This affects occupants including children in rear seating positions. Toyota has issued no recall, technical service bulletin, or warranty extension for this component. Complaints describing the same repeated actuator failures have been reported by owners of Highlanders and other Toyota models across multiple model years. I am submitting this record so the failure pattern is documented.

The radio keeps freezing up all the time along with the back tail light area going in and out. I keep smelling like burnt wire smell. Engine sound really rough.

The driver’s-side rear spoiler on my 2014 Toyota Highlander Limited AWD has melted, bubbled, and warped. The vehicle has been stored 100% of the time in a fully enclosed garage with no windows since new. It has only 65,000 miles and has received all service exclusively at authorized Toyota dealerships. There has been no direct sun exposure, accident, or misuse. Toyota dealer and Corporate attributed this to “solar convergence” and denied any repair assistance or goodwill coverage. This explanation does not match the facts given the garage setup and minimal outdoor time. This appears to be a materials/design defect in the black plastic spoiler. Similar melting/warping issues are reported by other owners on Highlanders and RAV4s, even on low-mileage garaged vehicles. Dealer replacement quotes are typically $2,700+. I request NHTSA investigate this recurring plastic failure as a potential defect in materials and workmanship. Attachments (upload with form): • Photos of the melted spoiler (multiple angles) I am available for any additional information. 05 May 2026

I noticed the smell of wires burning, a billow of smoke started emitting from the two levers used to heat the seats near the gear shift area. I was on the freeway and immediately pulled to the side of the road, turned off the car and called 911 before any flames were seen. There were no warning signs, lamps or other symptoms until the smell of burning wires and the smoke.

The contact owns a 2014 Toyota Highlander. The contact stated that a hybrid system warning alert was displayed. The vehicle was taken to an independent mechanic, where it was diagnosed and determined that the windshield wiring system had failed and that the windshield needed to be replaced. The vehicle was not repaired. The mechanic informed the contact that the windshield failure was associated with NHTSA Campaign Number: 18E107000 (Electrical System, Visibility). The dealer was not contacted. The vehicle was not diagnosed or repaired. The windshield manufacturer was made aware of the failure; however, the vehicle manufacturer was not made aware of the failure. The approximate failure mileage was 190,000.

Was driving 70 mph on nj 287 when all sudden I hear something that sounded like implosion and air was coming from sunroof. Ended up being sun roof glass flew out of car sunroof frame. Toyota knew it was a defect as they did inspection but did not want to cover it because they said it’s out of warranty. Thankfully no one was driving behind me at that time

Rear lights located both on the tailgate and body of the vehicle. The lights covers failed to remain adhered to the lights themselves and fell off and are partially adhered as a result of what appears to be a failure of the adhesion material . Two light covers may have been lost while driving. Unknown if their loss resulted in damage(s) to others. Without the outer cover results in the exposure of the lights to weather and potential failure. Review with Toyota of Orange service manager confirm the failure of adhesive/ manufacturing process of the lights

Installed (4) Firestone Destination Le3 tires in March 2022. All four tires became dry rot in just over 2 years, failed inspection at 2 1/2 years. 70,000 mile tires with roughly 28,000 miles left of the warranty.

Water leaks inside the car every time it rains. We checked the sunroof drain tubes. They are clear. It is getting in through the roof rail bolts. It runs down the pillars to the floor and underneath the floor carpet. The carpet is wet for long periods of time in rainy seasons. I am concerned there is going to be mold issues.

The vehicle is painted in Blizzard Pearl, which has a known peeling issue. Toyota never sent us any notification of an issue with the paint. A patch of the paint has peeled off of the top of the vehicle and has continued to grow larger. When we contacted Toyota, we were informed the period to fix this issue has closed and we would have to repair out of pocket. Our vehicle was mostly garage kept and didn't suffer the immediate failure of the paint. Blizzard Pearl is a color with an additional cost and has the most complaints for failure. Toyota has acknowledged the problem but did very little to ensure customers were notified, did not take into account Blizzard Pearl painted vehicles would fail at different times due to climate/storage of vehicles, and only provided a narrow window to their customers for this issue. The peeled paint has exposed the body of the vehicle to the elements, which will cause it to rust.

The contact owns a 2014 Toyota Highlander. The contact stated while driving approximately 40 MPH, the moon roof detached from the vehicle. There was no warning light and there was no impact to have caused the failure. There were no reported injuries. The local dealer had previously replaced a piece on the moon roof. The vehicle was taken to the local dealer, where it was diagnosed that the moon roof glass needed to be replaced. The vehicle was repaired. The manufacturer was contacted, but no additional assistance was provided. The approximate failure mileage was 99,000.

The lift gate will not open and close properly. It only works about 5% of the time.

The contact owns a 2014 Toyota Highlander. The contact stated that the tailgate failed to open and close properly or as needed. The vehicle was taken to an independent mechanic, who referred the contact to file a complaint with the NHTSA Hotline. The manufacturer was made aware of the failure. The failure mileage was approximately 87,000.

Some doors do not lock when the electric lock switch is pressed on the FOB or using the button on the door. Sometimes the doors that did lock don’t the next time. This is a security issue while driving the vehicle and another security issue when parking. It’s also a safety issue for the same reasons. The door’s electrical locking system fails and needs to be fixed.

As other 2014 Toyota highlander: issues with the power liftgate/rear door. Have problems open and closing the rear door to the point that it's not working properly anymore. Toyota is not responding unless you pay around $4,000 to get it fix.There are plenty of cases like mine and for the 2010-2023 they had a class action suite for the same problem, resulting in a mass recall to correct the problem. Why is not a recall for this year as well.

The glass from the panoramic sunroof detached from the vehicle while traveling approximately 60 MPH.

While driving car started singing and message came on dashboard about idling will cause the engine to turn off then the car turned off while I was driving it has happened multiple other times even after taking it to the dealership twice and then doing an update on it

On or about 12-01-2022 the windshield wipers stopped functioning. The result was an inability to drive the car in the rain and especially at night. It was impossible to see so we pulled over and waited for the rain to stop. After analyzing the issue the motor had failed. We contacted Toyota for a replacement motor. What we found: No wiper motors are available from Toyota, no aftermarket parts are available. We ordered a motor from Gladstone Toyota but after a couple of weeks began calling. What I was told: no wiper motors are available and there is no release date for when they will be. I began calling around and found that some dealers (TRD Shop) have over 200 on back order and only 80 were released last time they made them. where we are today: We have a vehicle made by Toyota that is unsafe to operate due to the fact the wipers don't work We replaced the wiper switch $232.00 but that only allowed the rear wipers to function further inspection verified the front wiper motor failed in conjunction with the switch that controls the rear wipers. I contacted Toyota engagement center and reported the issues. case #230106000756 they told us they would have a parts specialist contact us no later than 01-09-23 that never happened ans on 01-10-23 I contacted them to let them know we haven't heard anything. They have yet to reply or contact us regarding our back order. We purchased the vehicle new from Gladstone Toyota all maintenance done there. Issue is the vehicle is unsafe to drive in Oregon in the middle of winter, Parts are not available to repair Toyota unwilling to reply or see what they can do for us using their online engagement website.

Hi, the stereo sound on My Toyota highlander keep going in and out, I can start the car in the morning and the radio will work no problem but if I turn off the car or the radio sound or music will go away. after the car is off for about 3 to 4 hours period of time the sound will come back on when the vehicle is turned back on. This is the original Stereo system. Thank You

Steering column locked on several occasions while driving. Electrical systems blink on and off. Exactly as described in NHTSA recall #15V144000 and as far I can tell the exact same part number.

rear tailgate door non-functioning. auto door button does not work and door cannot be opened manually. serious safety issue if car in accident and side doors won't open. checked by dealer in dec. 2020, and they knew about problem and not covered under warrranty. toyota knew about problem in march 2016 and issued service bulletin T-SB-0023-16 which clearly states problem and how to fix in 8 pages.; and only covers 2014/2015 highlanders under warranty. no warning lights; tailgate failed in dec. 2020. vehicle only inspected by toyota dealer in roseville, CA. if Toyota is willing to fix some highlanders, why would they exclude others out of warranty? This makes the vehicle unuseable for a family that hikes, camps, plays sports, etc. and I feel is a clear safety issue if one exit out of vehicle does not operate!

The contact owns a 2014 Toyota Highlander. The contact stated while opening the hatchback, the hatchback failed to fully open as needed. The vehicle was taken to the dealer and the contact was informed that the support struts needed to be replaced. The vehicle was not repaired. The manufacturer was not contacted or informed of the failure. The approximate failure mileage was 43,000.

While driving the vehicle, the rear pane of the vehicle's moon roof spontaneously shattered into pieces. The moon roof has two basic components - the soft cover that lies under the glass moon roof and the 2-pane glass moon roof. Had the soft cover not been closed, the glass shards would have rained down upon the driver and passengers in the vehicle. The vehicle has not yet been inspected by an insurance adjuster, but there are numerous reports of this same problem occurring in other Toyota Highlanders on the internet. This issue appears to be being ignored by Toyota despite numerous reports across several model years of the vehicle. There were no warning signs of any kind issued by the vehicle before this occurred. This condition poses a serious threat to health and safety and should be addressed immediately by NHTSA.

This is a known problem with the Toyota Highlander where the Power Rear Door struts will not work in cold weather. They even issued a service bulletin but refuses to issue a recall on the defective parts. If the rear hatch refuses to close or open, it can be a safety hazard as these doors are very difficult to close and open manually as it requires a fair amount of strength to perform. From Toyota's own service Bulletin T-SB-0023-16: "Some 2014 – 2015 model year Highlander and Highlander HV vehicles may exhibit a condition in which the Power Back Door is inoperative or stops during operation. In some cases this condition may be associated with cold weather."

The tires have worn down to needing replacing after only 27,308 miles on them, these tires are rating and warrantied for 60,000 miles. Reviews online show other owners complaining about the same issue with premature wear and safety issues. When it rains, the vehicle will slip when attempting to drive, slide when stopping, and hydroplaning at less than normal road speeds.

The power back door is inoperative or stops during operation when the weather is cold. I moved to Oregon from Southern California in the spring of 2019. The problem started in the winter of 2020 & again in 2021. I looked it up and found a cars.com article that stated it was a problem and to call the dealer. I called Toyota and they didn't have it as a recall.I called the dealer in 2020 and they said they had never heard of the problem. I didn't take the vehicle to the dealer during Covid. I just went through another winter of dealing with a back door that would not operate properly.

Passenger door and rear left and right door doesn't lock or unlock with key fob, but can be locked and unlocked manually but if in a car crash and you have a child in the back seat it may creating a safety hazard if the doors are locked manually and you can't get your child out in a timely manner. I was told at the service center in Waldorf Maryland Toyota that it is a common problems, and there always changed on this make and model.

The power rear hatch will not properly open or close. The safety of others are at risk due to several factors. For example, the door will not open properly causing hands, fingers, and other object to get jammed in the doorway when trying to close it manually or when the door closes automatically without warning. It also does not close properly when the hatch is not working properly which could potentially be an issue while traveling where objects could fall out of the vehicle and injure other drivers. There are several articles online reporting the issue and will only be fixed if the vehicle is under warranty. Many of these vehicles are out of warranty due to their age. There was no prior warning other than a beeping noise when the door would not close properly.

The contact owns a 2014 Toyota Highlander. The contact stated while driving approximately 70 mph, there was a loud wind sound present. After opening the interior sun roof sliding shade, it was discovered that the glass sun roof had detached from the vehicle. The cause of the failure was not determined. The vehicle was repaired at a local repair center. The manufacturer was notified of the failure. The local dealer was not contacted. The failure mileage was 168,000.

MY POWERED REAR TAILGATE DOOR MALFUNCTIONS WHEN I ATTEMPT TO OPEN IT. ABOUT 80% OF THE TIME WHEN I PRESS THE BUTTON TO HAVE IT OPEN, IT CRACKS OPEN AND THEN STARTS BEEPING. THEN TO OPEN IT, I HAVE TO MANUALLY OPEN IT BY HAND.

THE REAR LIFT GATE POWER STRUTS NEEDED TO BE REPLACED AT 38000 MILES ON A 2014 VEHICLE. HAVE NOTICED NUMEROUS OTHERS COMPLAINING ABOUT THIS ISSUE ON TOYOTA FORUMS.

PASSENGER FRONT SEAT BELT WILL NOT RETRACT, WHEN I GOT OUT OF VEHICLE TODAY. DINGING SOUND COMING FROM SOMEWHERE WHEN WE DROVE IT LAST NIGHT.

NEAR THE END OF A 180 MILE TRIP, VEHICLE WAS ON HIGHWAY TRAVELING AT APPROXIMATELY 60 MPH WHEN LIGHT CAME ON SAYING ENGINE HAD STOPPED. ENGINE WAS SMOKING AND WAS COMPLETELY OUT OF OIL DESPITE IT BEING FULL AT THE START OF THE TRIP. MECHANIC FOUND THAT ENGINE HAD SEIZED AND HAD TO BE REPLACED IN FULL. UPPER MANIFOLD ALSO HAD TO BE REPLACED DUE TO PRESENCE OF METAL SHAVINGS. TRANSMISSION WAS LATER FOUND TO BE LEAKING OIL AND AT THIS TIME APPEARS UNFIXABLE. CAR HAS BEEN VERY WELL MAINTAINED WITH REGULAR MAINTENANCE AND OIL CHANGES AND THERE WERE NO WARNING SIGNS OF ANY ISSUES - CAR RAN SMOOTHLY UNTIL THE ENGINE SEIZED.

TAILGATE DOES NOT OPEN SOMETIMES. IT WILL DO A LONG BEEP. SOMETIMES IT WILL OPEN BUT NOT CLOSE ALL THE WAY. SOMETIMES IT WILL OPEN LESS THEN HALF WAY AND THEN DO A LONG BEEP.

THE REAR DOOR (HATCH) ELECTRICAL DOES NOT FUNCTION

DOOR LOCK ACTUATORS NOT WORKING. CAN NO LONGER USE KEY FOB TO UNLOCK/LOCK DOORS. POTENTIAL SAFETY ISSUE.

THE REAR DOOR LOCKS DO NOT LOCK ALL THE TIME MAKING IT POSSIBLE FOR THE KIDS IN THE BACK SEAT TO OPEN THE DOORS WHILE DRIVING DOWN THE ROAD ON MY 2014 HIGHLANDER. IT ALSO MAKES IT PRETTY EASY FOR PEOPLE TO STEAL STUFF FROM YOUR CAR. THIS IS A HUGE SAFETY ISSUE. IT IS A KNOW ISSUE AND THE INTERNET FORUMS ARE FULL OF PEOPLE WITH THE SAME ISSUE WITH ZERO HELP FROM THE DEALER. NEW LOCK MECHANISMS ARE 300 DOLLARS. I HAVE ALREADY HAD TO REPLACE ONE AT 75K MILES,. NOW I HAVE TO DO THE OTHER. THE VEHICLE NOW HAS 100K. *TR
