2024 Mazda CX-90: doors won't lock, open or latch

Filed Oct 29, 2026 · Body · MD

Rear door handles stick in the open position intermittently. Seems to happen more when weather is wet. Dealer fixed this problem once after a TSB was issued, but it is happening again. Dealer has not been able to replicate in person again and originally would not open case based on video of it happening. Upon contacting the manufacturer, the dealer was instructed to open a tech line case. If the door outer door handle stays in the open position when the door is closed it prevents the inner door handle from opening the door which caused my daughter to be stuck in the car until someone could let her out.

Drivers side interior door handle does not latch to open. No notable event lead to this - door opens from outside fine. Huge safety hazard.

Over my time owning this vehicle i have had several different safety concerns. although they have been resolved by the dealer, i have concerns for anyone purchasing this make and model. 1. lane departure. i have turned off lane detection because i have had the car try to auto correct and jerk me to the left into oncoming traffic 2. i have had incidents where the driver door was unable to be opened from inside. i had to roll down the window to open the door and get out 3. At a speed of 45mph, the vehicle suddenly went into limp mode. the car turned off and luckily i was able to pull over into a safe area. again i experienced the door locking from the inside. all issues and solutions have been documented at dealer services. these issues are of great concern and potentially could have been harmful or fatal. i no longer have trust in this model or company.

I have a 2024 MAZD CX-90 Preferred Plus AWD. I was driving my [XXX] grandson to preschool and it sounded as though the passenger's door opened while I was driving. In the split second I looked back to check, unfortunately, I hit a guard rail. My grandson was buckled in his car seat. his first words were "Meme, the door opened but I didn't do it". He was buckled in his car seat and I believe the safety door locks were on. There was no warning sound or light indicating the door was open while I drove. I pulled over, got out of the car and looked. the passenger's back door handle was positioned up but the door was closed. being so shook up, I didn't think to take any pictures. I then had messages on my car saying Dynamic Stability control malfunction - have the vehicle inspected and Engine Malfunction - have the vehicle inspected. I called my dealership to find out if there were any recalls on this type of problem (they said that there weren't any). I have come across a forum where a person states: "So can confirm 1st row passenger door does not provide any warning as well. Looking at the manual, I see that there is supposed to be a warning sound when any door/hood/liftgate is open while driving, as quoted below. If someone else confirms this is normal behaviour, then I think we should file a safety defect complaint with the federal safety agency and Transport Canada. “Door-ajar Warning Light/Liftgate-open Warning Light/Hood-open Warning Light The light turns on if any door/liftgate/hood is not closed securely. In addition, the warning sound is activated if any door/trunk lid/liftgate is not closed and the vehicle is driven. Close the door/liftgate/hood securely.” This was a very scary situation. I absolutely will concede that something did happen with this rear passenger door. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The exterior rear door handles get stuck in the open position. This is a danger and the door has opened while driving since the door handle did not close all the way. I have tried lubricating the both door handles with no improvement. Our car has never been in accident is approximately 18 months old. I have done research on the internet and it looks like this is not a new problem with multiple owners who have complained to the manufacturer in the past with no fix.

I am concerned about a serious safety issue with my CX-90. Both of the rear doors have consistently malfunctioned, failing to latch properly when closed. The door handles get stuck and do not fully return to their original position, preventing the doors from locking securely. As a result, the doors have swung open while the vehicle was in motion, putting passengers, especially children in the back, at significant risk. This is a critical safety concern that needs immediate attention. This issue goes back mid November 2024.
