Exactly what failed

NHTSA files every complaint against a named sub-assembly, not just a system. This is the difference between knowing it was "the engine" and knowing which part of it — the list to hand a mechanic.

When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

Recalls on the 2017 Mazda CX-5

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

United States — NHTSA

17V744000

TRAILER HITCHES

Mazda North American Operations (Mazda) is recalling certain 2017 CX-5 vehicles equipped with an accessory trailer hitch wiring harness. This harness may be routed such that there is insufficient clearance between the harness and the exhaust muffler, allowing the wiring harness to contact the muffler.

Risk: Contact with the muffler may damage the trailer wiring harness, potentially resulting in the trailer lighting being inoperative, thereby increasing the risk of a crash.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.

VEHICLE SPEED CONTROL

On February 14, 2023 around 3:30 - 4:30 p.m. (EST), I drove to the local WAWA. Upon entering the driveway of WAWA at a very low speed and depressing the brake the car failed to come to a complete stop. I pressed down on the brake as hard as I good, but the car did not come to a stop until hitting the security/safety bollard in front of the WAWA store. I did not get injured and no one else was injured. The front end of my car sustained over $4000 worth of damage. The insurance company repaired by car. I was asked by the insurance company what caused the front end damage. As I played the accident over and over in my head, I just could not see what I did wrong. My foot was on the brake. Also, I entered the entrance of WAWA at a very slow/low speed. After a few weeks I took the car to the Mazda dealer to let them know the car accelerates and engine revs. Also, the car jolts forward while decelerating from about 20mph to 10mph. The car dealer/repair shop could not replicate the problem. Was told to bring the car back in, if problem continues.

Windermere, FL Crash

UNKNOWN OR OTHER

The infotainment center has been randomly changing settings and radio channels. When it is taken over, I cannot regain control of it until it stops. I've seen online this called "ghost" controlling. It will increase the volume so lout, that I jump sometimes. Also, the rear camera mode of the system froze while I was backing up causing me to hit a vehicle parked across from me.

AIR BAGS

Blind spot monitoring system warning appears on dashboard of vehicle after driving for about 50-60 miles. This occurs only when I drive >50-60 miles in one trip without shutting off my vehicle. Speed does not matter. My sensors will not work until I turn off my car and turn it back on. This started as soon as I purchased my vehicle in July 2020. 1 previous owner (lease) before I purchased the vehicle. No prior accidents. Got the vehicle at ~30,000 miles. In January 2021, I drifted off the freeway and hit a tree going 35 mph during a snow storm. It was only myself (driver) and a passenger in the front seat at the time of the incident. Both were wearing seatbelts. The seat belts locked up, but airbags never deployed for myself or the adult passenger in the front seat. Driver sustained no injuries, but the passenger smashed their knee into the glove compartment and smacked their head on the window/seatbelt holder on the side of the interior wall. The passenger was asleep during the incident, which may have explained why they did not brace themselves. One minute we were on the freeway, then we hit a slippery spot, and within seconds we were head on with a tree. Drove away to avoid the possibility of any vehicles following my path and smashing into us. Car was still driveable somehow. Car was repaired after 3 weeks at Caliber Collision and looked great. Sensor issue persists still, but unrelated to accident. Mentioned it to Caliber Collision when vehicle was being repaired and they had a Mazda service person come out with a sensor machine and they could not find the issue.

ELECTRICAL SYSTEM

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.

ELECTRICAL SYSTEM

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.

Dickinson, TX

ELECTRICAL SYSTEM

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.

ENGINE AND ENGINE COOLING

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.

AIR BAGS

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.

SEATS

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.

Cranston, RI

ELECTRICAL SYSTEM

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.

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.

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
