2020 MAZDA CX-30

There is a module that should connect to the hatch door to open. That module in no longer available. Without the hatch door opening, in case of side impact and being pushed into something else, there is no way to get out of the car. This poses a serious safety hazard. I have contacted the Mazda dealership and I am told that the part is "retired" and there is no replacement part at this time.

I OWN 2020 MAZDA CX 30 WITH 66000 MILES. THE TRANSMISSION WAS SHIFTING WITH JERKY MOTIONS. ON JULY 14, 2025 I BROUGHT THE CAR TO PALISADES MAZDA IN ROCKLAND COUNTY NEW YORK TO HAVE TRANSMISSION LOOKED AT AND TO CHANGE TRANSMISSION FLUID CHANGED. AFTER I DROPPED THE CAR OFF LATER THAT DAY I GOT A CALL THAT THE TRANSMISSION WAS CONDEMNED. I LOOKED ON THE INTERNET WITH SAME YEAR MAKE AND MODEL AND SEE THERE IS A BIG PROBLEM WITH THE TRANSMISSIONS ON THESE CARS AND MAZDA IS AWARE OF THE PROBLEM. TSB 05-002/20 IS A BULLETIN ABOUT TRANSMISSION FAILURES IN THIS VEHICLE. MAZDA IS WELL AWARE OF THE TRANSISSION PROBLEMS

I am reporting a repeated and potentially dangerous transmission failure in my 2020 Mazda CX30. At 6 months old, the original transmission failed. Mazda confirmed it was defective and replaced it with a refurbished unit with 10,000 miles on it. That replacement is now also failing—within 4 years of the first failure. This means the car has experienced two transmission failures before reaching 5 years of service. This raises concerns about: •The reliability of Mazda’s factory parts •The quality and safety of refurbished transmissions Mazda uses in warranty repairs •A potential pattern of premature transmission failures on this model Repeated transmission failure can cause loss of power and control, posing serious safety risks to drivers and passengers. Mazda has all service records confirming both incidents. I am submitting this to alert NHTSA to a possible defect pattern that may warrant investigation.

The contact owns a 2020 Mazda CX-30. The contact stated that after starting the vehicle, the instrument panel made an abnormal sound. The contact then noticed that the odometer had inadvertently rolled back to 9,999 miles. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 49,000.

Low Engine Oil Light keeps appearing at seemingly random intervals. I will heat up my vehicle, begin driving, and sometimes after 10 minutes, sometimes after 20 minutes it will come on. I drove 2.5 hours and it did not come on at all. It first started Friday 11/29 and was driven to and from a few places and came on 50% of the time. The 2.5 hour drive occurred on Saturday 11/30 and the light did not come on at all.

Rear coil spring broke at ~33,000 miles under normal driving conditions. No warnings given in vehicle safety system and not included in recommended maintenence. Seen when inspected by independent service center. Cannot safely drive vehicle until replaced.

I am experiencing sharp edge on the Driver Side window up button. The Nicle plating is wearing off and causing safety concern. I have images of the concern. Will send upon request. Mazda is suggesting that I take the vehicle in for diagnostics and service. Their diagnostic cost is extremely high, and I am trying to avoid paying the diagnostic fee. Copy of the contents of my email sent to Mazda. I am experiencing sharp edge on the Driver Side window up button. I am wondering if this can be repaired under warranty or, should I report the abnormally to NHTSA to pursue a possible recall to have this switch replaced. I recall NHTSA had a recall on Hyundai vehicles a few years ago for the same issue. Can you please advise.

Defective windshield. There is visible warping in the windshield and Mazda won't cover the cost of the replacement. This is a known issue.
