MAZDA Complaints

My car is giving me various problems with a gear box(a) and accelerations(b). a. It shift from one gear to another on its own. The gear can be put in Reverse, but the light would indicate Park, and the car would not move. Sometime I put the car into Drive and the Parking Break would come up and wont let me release it until I put the car back into Park mode. I've already had multiple"glitches" like this. Couple of weeks ago, when coming out of a stop sign, the gear shifted from Drive into Neutral in the middle of intersection with 2 minors in the car. b. The car experiences acceleration problems every time it come from a stop. It moves very slow and "jerks" as if it is about to shut down. This problem has gotten getting worse in the last couple of weeks. I brought the car to Mazda dealer last summer, as the gear box would take forever to unlock for driving. They said it is normal and thats just like the car is. I have my 3 children [XXX] and [XXX] ) with me 95% of my driving. I have big concerns about this vehicle and its safety.

The head on the 2.4L engine of the 2019 Mazda CX5 has shown a manufacturing defect that Mazda has addressed in certain models, but not all of the models with this engine. This leaves a large amount of vehicle owners with the financial liability to pay out of pocket for Mazda's engineering and manufacturing defect that they know about. The oil leaks onto the exhaust manifold creating a fire hazard. When driving our car, we cannot use outside air on the vents, A/C because the intake pulls in smoke coming from the engine compartment. I brought the car in today to Mazda and was denied any help in the repair, I am continuing with Mazda corporate to try and reach a resolution. Currently this will be roughly a $7000 repair. I do not have an estimate yet from the dealership.

All 4 of my BH255/50R20 XL 109v NOKIAN WR G4 vehicle tires are exhibiting abnormal tread degradation and excessive sidewall cracking. The tire defect includes a circumferential crack along the top of all 4 tires, where the top of the tire's sidewall and tread base meet. Upon tire inspection, the structural integrity and safety of these tires with continued usage is questionable. The tires in question are only 26 months old and have approximately 31K miles of usage.

I purchased a 2019 Mazda CX-5 (As is) on July 20, 2015. On September 11, 2025, as I was traveling on a three lane highway. I attempted to pass another vehicle. As I was attempting to go around the vehicle, my Mazda suddenly began braking and quickly losing acceleration. The speed limit on the highway was 70 mph. I estimated my speed at the time was between 70 and 75 mph as I attempted to pass. Pressing on the accelerator pedal did nothing. I had to try and very carefully steer the car to the right hand side of the road while trying to avoid oncoming traffic approaching from behind. When I finally got the car off the road, this is when I noticed that the car had stalled. The car started right back up and I continued to my appointment. The "radar cruise control" was activated at the time of the incident. On September 15, 2025, I contacted the dealer where the car was purchased and explained what happened. I was asked to bring the car in that same day. The car was supposedly looked over and connected to the Service Dept.'s computer to see if any error sign appeared. Nothing showed up. I service technician was then asked to ride with me to see if the car would replicated the same stalling as it has previously done. We could not get the car to stall as it had previously done. Before leaving, a salesman asked me if I wanted him to explain the "radar cruise control" to me some more. I agreed. The salesman then proceeded to tell me that "the car did not stall, it was simply braking from the activation of the radar cruise control". Being an experienced driver, I told the salesman that the car had stalled as evidenced by the fact that I had to restart it. The situation was not resolved to my satisfaction, but no other offers were made by the dealer. I requested additional diagnostic work to be done, but the dealer refused to cooperate. I did take the car to another Mazda dealer, but could get no offer but to connect the car to their computer.

The contact owns a 2001 Mazda MX-5 Miata. The contact received notification of TSB: 3505H (Non-Methane Organic Gas (NMOG) levels exceeding standards. The contact recently purchased the vehicle. The vehicle was taken to the dealer, who informed the contact that the remedy was not yet available. The contact was informed that parts were no longer being manufactured to repair the vehicle. The manufacturer was made aware of the issue and informed the contact that a search would be done to find a dealer that had recall repairs. The contact had not received a callback from the manufacturer. The contact had not experienced a failure.

The authorized dealer, Cochran Mazda, previously bypassed the vehicle’s hybrid system and returned the vehicle to us stating it was safe to operate and that we could disregard warning messages until a replacement hybrid battery became available. Prior to this, we had reported repeated drivability concerns, including jerking during operation. We were advised that this behavior was normal for hybrid vehicles. While awaiting a follow-up service appointment, the vehicle displayed a “Critical Engine Malfunction” warning and experienced a significant loss of power while traveling across the Liberty Bridge in Pittsburgh, PA. The vehicle would not accelerate beyond approximately 15 mph and then stalled out on the bridge. We activated hazard lights and were able to proceed slowly to a nearby parking lot, where the vehicle required towing. This incident created a hazardous traffic condition and raised significant safety concerns.

The engine cylinder head cracked and is leaking engine oil. This component is available for inspection at Liberty Mazda or by an independent certified mechanic upon request. The cracked cylinder head caused significant engine oil leakage, which created the following safety risks: Sudden loss of engine power or stalling while driving Smoke emission from the engine bay Potential fire hazard if leaking oil contacted hot engine components These conditions placed both the driver, passengers, and others on the road at risk. The cracked cylinder head and associated oil leak were diagnosed and confirmed by Liberty Mazda, the authorized dealership that performed prior repairs on this vehicle. The dealership documented the issue and provided a repair estimate of approximately $5,400. No independent service center has inspected the vehicle at this time. The vehicle and cylinder head have only been inspected by Liberty Mazda. Mazda Corporate has not physically inspected the vehicle, but all service records and documentation of prior repairs have been submitted to them during the warranty dispute process. There has been no inspection by police, insurance representatives, or other third parties May 2025: The vehicle intermittently struggled to accelerate. At that time, no dashboard warning lamps illuminated, and the dealership initially reported no issues. June 2025: Following the timing cover repair, the vehicle experienced engine oil leakage due to incorrect sealant installation, which was documented. February 10, 2026: The dealership repaired the oil pan seal and replaced the sealant, refilling engine oil. February 14–15, 2026: Approximately four to five days after the February 10 service, the cylinder head cracked, causing a significant oil leak. All symptoms and related service events are documented in Liberty Mazda’s service records.

My fuel pump burned out after only 60k miles.... very expensive repair. Mazda said the problem was only with the early 2019 models so mine wasn't included yet my fuel pump did exactly what the ones included in the recall did, but I was left with over $1700 repair bill to replace the fuel pump. Obviously the "improved design" used in the second half of the year isn't really improved, and I've never had to replace a fuel pump on a vehicle with so few miles on it. We were sitting idle waiting for food at a restaurant and the engine just died and we were unable to re-start the vehicle. No issues prior to this, always kept fuel at least 1/4 tank or more full and no engine warning lights until AFTER the engine died.

My current vehicle has a headlight malfunction issue that has plagued the car since 2k. Under turning the swivel in the headlight will break or become off track.The headlight if it becomes off track the adaptive headlight will stick in place causing a lost of field of view at night. Mazda has warranty the drive side headlight due this issue. Their new headlight house was redesigned for 2024 year. It continues to be an issue. When getting the vehicle inspected they say it because of spirited drive and yet to fix the issue with programming or other means. This is common issue with refresh Miatas.In the forums many owners of the refresh are complaining about it. Mazda is aware of the issue but has not come out with a solution and dealer support not really there.
