MAZDA Complaints

Rear subframe corrosion on this vehicle. I am in a winter road salt region, the materials used for this vehicle's subframe are not compatible with consistent driving in this region. Similar vehicles (not mine?) were subject to a recall for the front subframe, but nothing for the rear. This rear subframe issues caused multiple failures of virtually every component of the rear suspension - control arms, rear springs, etc. The repair cost for JUST the subframe was $3813. Not repairing it was not an option - the vehicle had failed mandatory State of Maine inspection (a safety thing, if I'm not mistaken). This should be a Mazda problem, not a me problem. I contacted Mazda USA about this issue and got no response.

While accelerating from a complete stop at a traffic light on a multi-lane roadway, the vehicle suddenly lost all engine power without prior warning. The engine RPM dropped immediately to 0, causing the vehicle to stall in the middle of an active intersection and creating an immediate risk of a side-impact collision from oncoming traffic. All warning lights on the instrument cluster illuminated upon stalling. To clear the intersection safely, the vehicle was placed into Neutral and restarted. After shifting back into Drive and proceeding out of traffic, the vehicle repeatedly entered a fail-safe/limp mode every 30 to 120 seconds. During these episodes, the Automatic Transaxle (AT) light flashed, the engine shuddered severely, and the engine RPM fluctuated erratically, causing unpredictable acceleration and poor drivability. The sudden stalling in active traffic created a severe hazard to driver and occupant safety. The vehicle had not displayed a Check Engine Light or Transmission warning light prior to the complete stalling event.

The contact owns a 2024 Mazda CX-90. The contact stated that while her husband was driving 70 MPH with the cruise control activated, her husband attempted to deactivate the cruise control before exiting the highway; however, the cruise control failed to deactivate. The brake pedal was depressed, but the brakes failed to stop the vehicle. The contact's husband exited the highway and drove into the median to avoid crashing with other vehicles. The driver turned the steering wheel, causing the vehicle to flip and then slam into the ground, fracturing both axles. The cruise control then deactivated. The contact stated that only the front driver's side air bags deployed. The driver suffered hip and arm bruises, while the contact suffered a lump on the head, and as bruises on the collarbone and arm. The driver received medical attention at the scene, but the contact declined. A Police report was filed. The vehicle was towed to a tow yard but had not yet been declared a total loss by the insurance company. The contact stated that prior to the failure, the message "Trailer Attached in Tow Mode" was displayed and the vehicle was taken to the dealer, who replaced the wiring harness due to corrosion. The manufacturer was not made aware of the failure. The failure mileage was approximately 15,000.

On several occasions, moving the gear selector from Reverse to Drive, the transmission has failed to engage Drive, with the dashboard displaying "D" and the vehicle moving in reverse upon throttle application. Fortunately, objects, pets or pedestrians were not present behind the vehicle during the occurrences. The dealership was unable to duplicate the condition and found no software updates or other notices from Mazda addressing the issue.

While driving approximately 50 mph, we heard a sudden, extremely loud bang, followed immediately by the sound of shattering glass. We pulled over and discovered that the panoramic sunroof had shattered and appeared to have exploded outward. There was no collision, no object that we saw strike the vehicle, and no warning before the failure. The glass remained largely in place but was completely fractured. This occurred while my family was in the vehicle, including my young children. The sudden explosion startled the driver and created a potentially dangerous driving situation. I am concerned that a spontaneous sunroof failure at highway speeds could cause a driver to lose control of the vehicle or result in injuries from flying glass. I am reporting this because I believe it represents a serious safety issue that should be investigated to determine whether this is a manufacturing defect or other vehicle safety problem.

My tires are dangerously bald with less than 22,000 miles. They were no longer safe to drive. I believe Mazda is aware of the defective Falken 275/45R21 tires.

The low beam wiring gets hot and melts the connectors to the bulb connection. The low beam headlights have been replaced 8 times in a year due to low visibility. It's like turning off the headlights but they are still on. It's been going on for years. I've taken it to Mazda and the mechanic told me they had a vehicle there now with the same problem and have not figured out the problem yet. Wiring harness has been replaced to the low beam, the connectors and bulbs replaced fuzes and nothing seems to fix it, the battery keeps needing to be replaced as well, alternator has been replaced. This is a safety issue due to the fact that the low beams are so dim the driver can't see to drive without using high beam headlights to drive and they are just like having regular low beams on.. I've used halogen as well as led trying to fix it nothing has worked

When I first got my Mazda CX30 2024 New lease ,my Breaks were very weak & didn't perform as new. Only 2 years later w 9K miles on it, Mazda states my breaks need to be replaced. My rotors need to be shave. A whole list of services on a car thats 2 years old. My concern is, break service at 9K confirm my car wasn't new and that Mazda put my Safety at risk w Old Breaks... Mazda is hiding somerhing about my breaks playing games...in the mean time I feel my safety is in jeopardy with defective breaks that maza should fully cover under warranty. Which they won't honor. Putting my safety in jeopardy

Phantom Blind Spot Monitoring occurred while driving 70-73mph. Right driver side blind spot turns on for almost 5 minutes with no other vehicles around. Switching lanes causes lane departure warning system to activate.
