2023 Mazda CX-50 Problems

Rear differential failure, and side seat tear on 2023 Mazda cx 50

On 1/14/2026, I was pulling into a parking space in a parking garage when the vehicle abruptly accelerated causing the vehicle to hit the concrete wall in front of me. No braking assist or front collision warning issued. Airbags deployed. The car is currently at Joe Myers Collision Center in Houston, Texas to obtain an estimate for repair. The police did not respond to reported incident. Incident was reported to my insurance company immediately.

The contact owns a 2023 Mazda CX-50. The contact stated that while driving at approximately 38 MPH. The contact stated he was approaching an intersection when a vehicle in front of him attempted to make a left turn but slowed down. The contact was unable to depress the brake pedal and turned the steering wheel to the left to avoid the crash, but he crashed into the corner of the passenger side rear bumper of the other vehicle. The contact was not sure of the damage to the other vehicle; his vehicle had damage to the right headlight and the front quarter panel. The contact stated that his vehicle was equipped with a front collision avoidance system, but the system had not engaged. The contact stated that no persons were injured. The contact stated that the police were on scene and wrote a report. The vehicle was driven to a collision center for repair. The contact had not had the vehicle diagnosed. The vehicle had been repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 57,000.

I am reporting a potential airbag system/emergency brake failure in my 2023 Mazda CX-50. I was involved in a rear-end motor vehicle accident at approximately 60 mph while my vehicle was completely stopped. I then hit the person in front of me. At the time of the impact, the airbags did not deploy, and I received a dashboard message indicating an airbag system malfunction. Since then, the emergency brake turns on and off on it's own at any time. Due to the severity of the crash, I am concerned that the airbags should have deployed, and their failure raises a serious safety concern. I sustained injuries (multiple fractures) as a result of the collision. I am requesting a formal investigation into possible defect or malfunction in the airbag system and emergency brake system.

The temperature control dial on the climate control system behaves erratically and inconsistently. When turning the dial to increase temperature, the displayed temperature sometimes decreases. When turning it to decrease, it sometimes increases. The dial also jumps multiple units rather than incrementing one degree at a time. The behavior is unpredictable and occurs regardless of whether the engine is warm or cold. This issue has been confirmed by multiple other 2023 CX-50 owners in owner forums, suggesting a manufacturing defect in the encoder mechanism for the temperature control knob. The dealer confirmed the bumper-to-bumper warranty has expired but has not offered a resolution.

When adjusting the temperature in the car with the dial, it does not respond correctly. It either jumps up or down by multiple degrees. This causes to take your eyes off the road to try to adjust the temperature. No warning lights came on and pushing lighter or harder on the dial does NOT fix it. Only driver side is currently having this issue.

Wear of Strut Bearing causing crunching sounds at low speed braking and turning. Dealer reports this is due to dirt and debris getting up there. Vehicle has 34,000 miles (out of warranty due to time) and has had only light use off-road on dirt roads (2 camping trips). Not repairing can cause further damage and failure of suspension components. Vehicle marketed as off-road capable but components not protected properly from dirt/debris from driving off-road.

On [XXX], our 2023 Mazda CX-50 experienced a failure of the control arm, which was confirmed by Auffenberg Mazda of O’Fallon, IL, to be a manufacturer’s defect. Despite this, the dealer informed us that the vehicle was safe to drive. However, Mazda corporate contradicted this, stating the vehicle is unsafe to drive and instructed us not to operate it. We were informed that the replacement part will not be available until sometime in July 2025, leaving us without a safe vehicle for nearly two months. Both Mazda corporate and Auffenberg Mazda of O’Fallon, IL, have refused to provide a loaner vehicle or commit to reimbursing rental car expenses during this period. Additionally, Mazda corporate has failed to maintain consistent communication, not returning calls when promised and leaving us without timely updates or resolution. This situation poses a significant safety concern and financial burden, as we are left without a reliable means of transportation due to a confirmed manufacturing defect. We request that the NHTSA investigate this issue, including the conflicting safety assessments provided by the dealer and Mazda corporate, the delay in part availability, and the refusal to provide a loaner vehicle or rental car reimbursement. We also urge an evaluation of the control arm defect to ensure other Mazda CX-50 owners are not at risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The driver's door is not opening from the inside. To open the driver's door while I am in the vehicle, I have to roll down the window and use the exterior door handle to exit the vehicle. This is a huge safety concern, as the window cannot be rolled down manually. If the car did not have power, I would have to break open the window. The potential for being trapped in the car with this defect is high. Several other owners of this car have reported this: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My rear differential is going out at only 40,000 miles. Ive heard from many other people that this is a widespread issue, and i feel requires a response from the company.

Keyless Entry: I have had this vehicle for about 6 months and over that time, more than 3 separate times the keyless entry hasn't unlocked. It may take 2 - 3 tries. It has never failed to eventually unlock. I don't know that it ever failed to lock because approaching the car it would have already been unlocked. I don't always hear it actuate. Auto-lock: I assume the same proximity system that is supposed to detect the keyless fob inside/outside at a distance - could be responsible for failure to auto-lock upon leaving the vehicle. Dependably securing vehicles is a major security problem is some areas and that is a major impetus behind keeping cars locked/and unlocking only as the driver approaches. Imagine being in a desolate parking garage late at night and the door chooses that particular moment to fail to cooperate. Or, if a driver trusts the auto-lock to work and it doesn't. App: In fairness, Mazda does have the MyMazda app that will eventually report to a phone that the car detects that it is unlocked. It seems unreliable. Currently the app has a "star rating" of about 1:10 3 or fewer for various issues. You can't make everyone nor every device cooperate - and to a degree, I can't say that's the problem. I would expect something wrong with the fob or proximity detection system. Just as likely, the door lock actuator has issues. Summary of Problem: Maybe about as many times, the app informs me the car is unlocked when it should have auto-locked. So is it a keyless, app or door actuator problem? Or, a combination? And, it works MOST of the time. I eventually asked myself if I would want someone's wife or kids out there and door locks fail at a critical moment. I must say, I haven't reported it formally because of the intermittent nature and the fact I have an issue with Mazda that has existed from the beginning. Major body parts are poorly fit and beyond contestation. If Mazda ignores that constant issue, an intermittent problem is likely to be as well.

The rear lift gate came open while driving on the freeway on ramp. No buttons were pushed to open the lift gate. I had to pull over to the side of the road to safely close the lift gate.

The contact owns a 2023 Mazda CX-50. The contact stated that the steering wheel was loose. The contact was able to move the steering wheel up and down very easily. The contact stated that the vehicle was involved in a crash 7 months ago, and the steering wheel started to become loose one week ago. There was no warning light illuminated. The vehicle was not taken to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was 40,585.

Turning steering wheel to the left seems to stick somewhat between 9 and 11 o'clock position. It seems more likely happening in cold weather and more obvious at lower speeds.

While driving 72mph on the interstate at 6am on 7/21/26 the sunroof exploded. No foreign objects made impact with the vehicle and there was no sudden temperature shifts. The glass had no previous defects and it shattered into tiny pieces, failing into the car. The sun shade was open at the time. The vehicle is being serviced at a glass repair shop who noted this is a common issue with Mazda sunroofs.

2023 Mazda cx50 has a leaking panoramic sunroof and was noticed on February 27th, 2026 after a hard rain. Got an appointment with my dealership on March 4th, 2026 I bought my car through, they denied helping me of any kind and diagnosed my car with a cracked sunroof bypass drain plug and the part can’t be replaced, the entire panoramic assembly needs to be replaced. I believe this is a safety issue and Mazda Corporate will not help either. Water should not be coming into my car with electronics at risk!

If any liquid or debris material enters the console cover area where many controls for the car are located, the “command switch” (as described by the Mazda dealer) underneath is destroyed. Many items are affected as noted above (some of which I could not check off). They have not responded as to whether some type of shield or even tape could be used to prevent this fault.

After installing Mazda Genuine Accessory 4-pin trailer wiring harness (P/N VA40-V7-780A), and Mazda’s trailer hitch as well, found that the wiring does not operate correctly. When the turn signal or hazard lamps are activated while the brake is applied, the trailer lamps will operate erratically, flashing faster for a few cycles, then return to a normal flash rate before the erratic behavior repeats. The Mazda’s lamps operate normally. This has occurred with two different trailers, one with incandescent and one with LED lamps. To verify that the concern wasn’t with the trailers, a small trailer-side harness was made that used a floating ground, and with either incandescent or LED stop/tail/turn lamps plugged into it the concern was the same. Dealership verified the concern and verified correct installation of the vehicle harness. They were able to replicate the concern on another CX-50 as well. They reached out to Mazda’s technical assistance, but have not been advised of a repair. This was several months ago. Mazda’s customer service was of no help. May not be compliant with FMVSS No. 108, S14.9.3.5.3, S14.9.3.9.3, and Figure 2. Concerned that this may increase the risk of another vehicle striking a trailer attached to the Mazda. The vehicle is available for inspection upon request.

I brought my car in to get it checked as the back drivers wheel was making clicking sounds when slowing down, both with and without breaks. I spent two weeks on my own trying to see what caused the car to make the sound when driving but was only able to learn that it makes the sound when slowing down, and disappears when driving at higher speeds. When brought in, the dealership was unable to tell me anything about the issue, as they were "unable to pinpoint it". After a few days, they were able to tell me that the issue is the differential, and that they would be unable to get the part. The differential is part of the axel, and is what allows the car to turn at different speeds. This is a serious issue and the car is less than a month and a half old with less than 1500 miles on it. The car itself is brand new, has never been used by anyone other than me and is having issues this quickly. The differential was inspected by the dealership, I am unsure if it was inspected by more than one person. But they are unsure as to when this issue would be getting fixed, and that car is my only transportation. The part has yet to be inspected by anyone other than the dealership. There were no warning lamps, signs, etc, only the sound of the back wheel clicking to show that there was an issue. Again, the car is less than a month and a half old, less than 1500 miles on it and this issue is incredibly dangerous.

Purchased the vehicle 5/20/22, mileage today is 1050 on 7 30 22, and the Goodyear reliance drivers side tire has a large dimple on sidewall, noticed it about 10 days ago and have had no response from dealer. Stopped driving it due to excessive heat wave and just common sense. Can easily notice it. And no, did not hit anything with tire, ever. I do not have any repair bill yet. I can’t send a pic due to reception.here. Getting a ride to town Monday if there’s any way to add it. Please let me know. Thank you.
