Mazda CX-5 2017 — Reported problems

My 2017 Mazda CX-5 has experienced a recurring condition more than six times involving sudden jerking, rapid deceleration, and loss of normal accelerator response during extended highway driving, often while cruise control is engaged. On multiple occasions the engine has also shut down. On 09/11/2026, while traveling south on I-35 at approximately 80 mph with cruise control engaged, the vehicle suddenly began jerking violently and rapidly losing speed. Normal accelerator response was lost and a vehicle behind me nearly struck my vehicle. I was able to reach the shoulder just before the engine shut down. The vehicle would not restart and required towing. There was little or no meaningful warning before the loss of power. The vehicle was inspected by a Mazda dealer. I specifically reported the recurring highway jerking, deceleration, loss of throttle response, and shutdown concern. An aftermarket OBD-II device was removed after the dealer identified parasitic battery draw. The dealer subsequently stated in writing that the battery and alternator were healthy and that the vehicle was “operating as intended.” On 10/09/2026, with that device no longer installed, the same symptoms occurred again during highway travel and the vehicle again became disabled and required towing. The Mazda dealer has now verified the drivability concern and reported a Fuel Rail Pressure Sensor “A” Circuit Low fault and low fuel pressure. The dealer is recommending replacement of the high-pressure fuel pump as an initial repair, followed by further testing of the in-tank fuel pump. The vehicle is currently available for inspection at the Mazda dealer. NHTSA’s VIN lookup currently shows 0 unrepaired recalls. I am reporting this because sudden loss of acceleration and power at highway speed creates a serious collision and roadside safety risk.

My car started to smell like gas. I brought it to a shop and there was a leak in my high pressure pump in which the gas was leaking on to my engine. I paid $1600 to have this replaced and there is only 88,000 miles on the car.

The radio is uncontrollable by driver. The radio the self dial from Bluetooth. Even if not connected, the radio surprises this driver by playing the radio unexpectedly at the highest rate. Due to the buttons not working, driver cannot turn down the radio causing safety concerns for being scared and distracted. There are no warnings. Mazda is unwilling to assess without pay.

There is a consistent issue with the “ghost touch“ and the electrical system so when you’re going down the road, the musical will change. The music will blast up or down randomly it’ll get stuck and it’s very distracting. It will hang up on people while you’re having a conversation through the car phone. This was a recall for Mazda 2014 through 2016 and they need to extend it because it was still happening with my 2017. This is my first experience with Mazda and it has not been a good one as far as this goes. I do a lot of driving and phone calls and music are very important and stuff randomly changing or getting stuck while you’re driving and then trying to fix it is very dangerous.

Infotainment system randomly makes its own selections. Turns volume up and down, changes settings, changes stations... etc. Anything that can be controlled on the screen is at risk of being randomly hijacked. Once, my drivers assist volume was unexpectedly turned to full blast and randomly shouted "navigation assistant will be at this volume. " I jumped so badly I actually could have crashed if I hadn't been at a light.

The contact owns a 2017 Mazda CX-5. While driving the vehicle, the engine overheat warning suddenly illuminated on the dashboard cluster panel. The contact pulled over immediately, restarted the engine, and coasted the vehicle to a local, independent mechanic shop. The independent mechanic diagnosed the issue as a blown head gasket. For a secondary inspection, the vehicle was transported to an authorized Mazda dealership. Dealership technicians determined that the engine cylinder was actually cracked and recommended a full engine replacement. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 92,000.

Last week, the airbag warning light illuminated on my dashboard. Please be aware that this marks the fourth occurrence of this issue. Each time I bring the vehicle to the dealership, they provide a different explanation, and I am required to cover the repair costs. I have been informed that the vehicles were manufactured with a defect, causing the wiring harness to corrode at the junction where the temperature sensor connects to the engine, which measures the coolant temperature. Additionally, on two occasions, I was told that the wire had disconnected from the airbag connector. During my most recent visit to the dealership on 5/21/26, I was informed that an item in my glove compartment had dislodged the wire from the passenger side airbag module. This situation is extremely concerning, as it suggests that the wire can easily fall out or become loose from the airbag, given that there is no barrier between the glove compartment and the airbag. It is important to note that this issue arises each time I start the vehicle while it is stationary, and this vehicle has never been involved in an accident nor have the airbags been deployed.

My car only has 65k miles on it and the rear differential failed and needs to be replaced. I am seeing this posted online by many Mazda CX-5 owners well under the mileage this typically happenes but out of the warranty period. Mazda should start a recall or compensate owners for this. its never been in an accident simply a commuter car used around town

During a one-hour car ride, the front passenger side seat heater burned a hole through the seat, damaging my wife's skirt and leaving a hole in the upholstery. The overheating definitely originated within the seat. We immediately turned the seat heater off and have not used it since. It could have started a fire, which is very scary, or burned my wife, which is a serious safety risk. This issue has been mentioned by other Mazda owners, but I cannot find any recall reports. There were no warnings prior to the burning. The component is being taken to the dealership to be examined today.

UNKNOWN The infotainment system started malfunctioning on its own. Changes channels on radio, goes into settings and makes changes. Calls phone numbers etc. Does it more in the cold weather

The infotainment system suffers from ghost touching. It has gotten out of control even after a “recall” fix at the dealership. Without being touched the volume changes, the stations change, the presets change, the car makes calls to my contacts. I am often unable to control the screen as it turns the car to max volume while driving. It is extremely unsafe, distracting and alarming.

Dashboard lit up like a Christmas tree. Multiple warning lights all at once. This issue has been reported on multiple Mazda vehicle years. Took to Delker Auto repairs. Is electrical problem. Stated that so far nothing wrong with components. Will have to hunt for. Mazda has known electrical issues. In addition, your file upload will not let me upload picture even though it's in correct format. I can send separately.

CX-5's infotainment system RANDOMLY, AND WITHOUT WARNING STARTS BEEPING AND CHANGING OPTIONS WHILE DRIVING, A VERY DISTRACTING EVENT. I TRIED TO SHUT THE SCREEN OFF BUT IT COMES BACK ON RANDOMLY AND CAUSES CONCERN AND DISTRACTION WHILE DRIVING, IT HAS BEEN HAPPENING FOR YEARS NOW AND OF WHAT I READ MAZDA WILL NOT CORRECT THE PROBLEM

The infotainment system in my 2017 Mazda CX-5 exhibits dangerous behavior consistent with known defects described in the Mazda Infotainment Class Action Settlement (Case No. 8:21-cv-01355). The infotainment system and touchscreen repeatedly activate critical functions on its own (“ghost touches”), sometimes going black, changing critical settings, disengaging phone calls as well as unexpectedly activating phone calls, and navigation features engage or freeze unpredictably. These malfunctions distract from safe vehicle operation, requiring driver attention to manage the malfunctioning display. The vehicle’s display is integrated with backup camera, audio, and Bluetooth controls, so these repeated malfunctions cause safety concerns while driving. Mazda and the dealership have refused to repair the defect under the Limited Warranty Extension established in the settlement, incorrectly claiming the issue is unrelated to the CMU (connectivity master unit). However, these symptoms are identical to those described in Mazda’s internal service bulletins (CSP13 and TSB 09-022/17) and covered by the settlement. I believe Mazda is failing to properly address a continuing safety-related defect that impacts infotainment stability and driver concentration. These issues have occurred for years and are continuing nearly every time I operate the vehicle.

Not an "incident" per se. Front passenger Seat Belt is difficult to clasp.

Rear differential failed around 97,000 miles. We were three months past our certified pre-owned warranty. Total cost to repair was around $4400 after a discount on parts and labor through our Costco membership. Contacted Mazda to see if they’d be willing to provide any assistance to cover the repair, they declined. Service advisor told us that it was a catastrophic failure that we did not cause. We purchased this car in 2020 and have always had it serviced at the dealership and at no point did they bring it up as it being an issue. The rear differential should not fail.

I purchased this vehicle on the 10th of September. BY the 12th I I noticed the infotainment system was doing its own thing without me touching anything. The next day it did the same thing I E.changing stations on its own,volume going up or down etc...

Rear differential began to leak. Mechanics (3) looked at the part and discovered play in both right and left side axles leading into rear differential along with loud clanking noises inside the differential itself. Seal areas on both sides of unit had extensive play. Diagnosed with worn gears inside rear differential. Vehicle is only 8 years old (bought brand new) and has 74,110 miles. Complaint filed with Mazda claiming that gears and rear differential should not have failed given the mileage. Mazda has advised me that the car was out of warranty (5yrs/60k mileage) that the repairs were not covered. They wanted me to drive my car to a local Mazda dealer but I declined since driving it may/would have caused more damage to differential. Advised them to have their mechanic go to my local repair facility where part was replaced and pick up the differential for verification. Research online has indicated other owners has suffered identical issues. Have not heard anything back from Mazda. Total cost to replace $3,993.49

My vehicle has had the "Ghost Touch" issue that has been reported on many Mazda vehicles and even had a recall for the 2014-2016 models since I got the car in 2018. Mazda has refused to do a recall or cover repairs even though it's still being reported as an issue on multiple different models of Mazda. This happens on a constant basis and just keeps getting worse. Here is the original recall notice from NHTSA: https://static.nhtsa.gov/odi/tsbs/2019/MC-10164268-0001.pdf

Infotainment system "touch" screen doesn't work and I experience "ghost" touching where it's as if someone is actually pressing the screen to toggle between the different functions, raise/lower the volume, etc., when my hands are no where near the screen. It's a very dangerous distraction when it happens while driving.

The contact owns a 2017 Mazda CX-5. The contact stated that while driving 30 MPH, the air bag warning light illuminated on the instrument panel. The vehicle was taken to the dealer, who diagnosed a failure with the air bag connector. The vehicle was repaired, but the failure reoccurred 9,000 miles later. The vehicle was taken back to the dealer, who again diagnosed a failure with the air bag connector. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 24,000.

Rear differential failed at roughly 80,000 miles. Depending on failure, unexpected loss of traction or a locking up of the drivetrain could occur. We were lucky to catch it before then. Dealer confirmed issue with no clear cause. No warning lamps/messages/etc indicated that the part was failing. The only thing we noticed was increased highway noise, which could easily be ignored by someone who is not as aware of good/bad car noises.

The rear camera dose not always display on the LCD screen, likely due to the ghosting issue with the infotainment system which randomly cuts in and out. This poses a safety hazard when backing up. Despite repeated complaints from other owners as well regarding the LCD screen, Mazda will not cover cost of replacing the LCD screen. I had a 2014 Mazda 3 for which there was a recall for the same issue and they covered it. So I don't understand why they won't do it for this vehicle. Being able to see what is behind the vehicle when backing up is a safety concern. I provided date of most recent occurrence, but this has happened multiple times before.

Car was making popping noise, got it checked out at mechanic. Said rear differential had metal in the oil.

Touchscreen continues to change to different screens Ghost touch screen malfunction is know to dealer as prior year models have also had problems and recall was issued Dealer won’t cover cost of repair as it’s out of warranty This just started so I wouldn’t have known during warranty The dealer will repair for $750 which is not fair as it’s a known problem It is very distracting while driving and even if I turn the display off it will come back on

Coolant leak, caused engine failure

Twice now, my 2017 Mazda CX-5 stalled on the highway with a check engine light popping up--both times was driving around 60-70mph for a couple of hours and had about a quarter tank of gas left. The first time, no code was found, but the second time, after a deeper diagnostic, the dealership found a P0192 code. After reading here and many other places online, based on the code and the car's behavior, it really sounds like the Denso low-pressure fuel pump is to blame; that's the source of the recall for 2018 and 2019 Mazda CX-5s experiencing this same issue [XXX] ). If the 2017 model also uses that fuel pump, why isn't it included in the recall? If this dangerous and erratic car behavior is due to a faulty part, it really should be covered by the recall. Shame on you, Mazda. Lives are at risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle – display has a ghosting issue with the screen keeps on changing without me, touching the controls. It will switch from one function to another function independently, and sometimes the screen goes blank. This display was replaced under recall in 2020 and I’m starting to have similar problems now in 2024 for the last 10 months. When the screen goes blank, this compose a safety hazard.

There is a known issue of "Ghost Touching" on the infotainment system on 2017-2020 Mazda's. The ghost touching causes the infotainment center to randomly self-select options on the screen, which is highly distracting. The following are experiences I've had while driving (sometimes going 70MPH on the interstate), where my infotainment center begins to make selections on it's own: Unpausing paused music Making random phone calls Opening text messages and selecting the reply button Flipping between screens continuously Ending phone calls This is extremely distracting and dangerous. Mazda is aware of this issue. I had my screen replaced in 2020, and replaced with another faulty screen that I now have to get replaced again.

This car has an issue with 'ghost touches' on the infotainment screen. We had it replaced under warranty in January 2020, and the same issue is happening again. Searches online show this is a widespread problem and Mazda wants to charge $1,000 to fix it this time. It is a distraction, turns music on/off volume up/down and can cause dangerous unexpected distractions.

Vehicle Infotainment Center - the touch screen will automatically select options and click options while driving, causing a distraction and most recently attempting to enable a child lock. It will do it while the car is both driving and while stopped. It will randomly do it on both the Radio Screen and the Navigation screen.

The infotainment system has a known problem called "Ghost Touch". The screen will randomly change from am to fm radio, make phone calls on its own, change screen during navigation. Mazda knows of the issue with this model. This should be a recall as it can severely distract a person while driving. Mazda says this is not under warranty even though I have extended warranty and the millage is only 32,000. Please make this a recall before a serious accident occurs.

Cx 5 2017 mazda. Purchase at the mazda dealership in 2021. Car has been burning oil. At 2000mils my oil level on the dipstick is at the lowest mark. I have to add 1gt oil to bring the mark to the correct level.

The sunroof exploded while driving on the interstate. The noise was terrifying and I didn't know what it was at first so I slid the sunroof cover open a little and glass started coming down. I pulled over the interstate (dangerous in addition to the glass) and the sunroof had exploded. I was not going under an overpass and no vehicles in front of me, nor did I hit anything that kicked up

The center screen started self selecting on its own, and randomly choosing options that included going into the setting for Adas system and turning stuff off and on.

Exact same issues as NHTSA Recall No.19V-272 -- Manufacturer Recall No. 3219D. -- Affected P/N: TK52-675XO B

My touch screen, has been acting up. While driving, the navigation system will automatically change prompts while driving. It will change to music, random dials, consistently change to random dials. I am unable to stop the dials from changing. I have read on the internet people are calling this "ghost touching". The volume will randomly go up high while driving. I am unable to control the volume or prompts. This is dangerous while on the road. I am unable to hear first responders while driving in traffic. This is a huge distraction. Many people I am reading are going through this with their Mazdas... This is costing us more than 3,000 or 4,000 to get fixed. I am unable to get this fixed for this price. I am unable to get a new car.
