MAZDA Complaints

During normal operation of the car the radiator sprung a leak which could have resulted in leaving us stranded with our young kid. this was verified by the dealership who's only solution has been to replace the radiator at our expense. There were no warning lights or other indications of the damage other than coolant leaking from the bottom of the car

I bought my 2024 Mazda CX-90 PHEV 10 months ago with 22000 miles on it and no and now has 29000 miles on it. First thing I had a issue with was a Motor Mount was bad, took 12 weeks to get part was told it was safe to drive. Next, since I have had the vehicle I have been having a issue with the transmission making a noise while both shifting from first to second and also on down shifting. It does not happen all the time but is happening. I took the vehicle in to the dealership to have it looked at and they were able to reproduce the issue. When they conferred with Mazda on the issue they were told that it was a known issue but there is no fix for it at this point and was dertermined safe to drive. I also talked to Mazda myself who also told me that it was a known issue but there is no fix and determined it safe to drive. I love the vehicle but to have this noise keep happening and being told they are working on a fix does not make me feel confident in the vehicle with this especially when my wife also drives it. My biggest question is this is a 2024 Mazda and I am told the 2025 also has the same problem. How long is the answer were working on a fix to long to believe that they actually are since there are now 2026 and soon to be 2027 models coming out. I am being told it is only the PHEV vehicles having this issue which explains the reason the PHEV model I believe is being discontinued. Would love to hear from you what my recourse would be. Thanks in advance for your time

The vehicle exhibits a repeatable low-speed driveline-related problem consisting of pronounced clicking or clunking from the driver-front area, fore-and-aft jerking, and harsh engagement during deceleration and light on/off-throttle transitions, particularly around 15–17 mph; the behavior can become significantly worse over rough or uneven terrain. The exact failed component or system has not yet been identified. The vehicle is still essentially new, with fewer than 5,000 miles, and has not yet reached its first scheduled service interval, so it has not yet been formally inspected for this condition. No warning lamp or diagnostic message has appeared. Other owners online have described a similar low-speed clunking and jerking phenomenon, and Mazda has issued at least one prior transmission-related TSB addressing somewhat similar harsh shift behavior, although that bulletin does not appear to apply to this vehicle or this exact symptom. The vehicle is available for inspection upon request. The concern presents a potential safety risk because the vehicle can unexpectedly jerk, lurch, or abruptly change driveline load during ordinary low-speed driving, which can make accelerator response and vehicle speed less predictable in traffic, parking lots, intersections, or on uneven surfaces. The symptoms began within the first few thousand miles and remain repeatable.

Recently, while driving our Mazda CX-90 (2025) we noticed a persistent and constant odor of fuel/gasoline vapors arise from the vehicle. We noticed this after driving the vehicle approximately 120 min from Las Vegas, NV to St. George, UT. The smell was intoxicating and nauseating. I took it into 2 local dealerships to investigate and called Mazda USA headquarters and spoke to a supervisor located in Irvine, CA. She explained to me that she gets complaints like this all the time during the summer months and that the larger Cx-90 is known to have the issue of leaking gasoline fumes/smelling of strong gasoline odor. I expressed my concerns for the safety of my family and surrounding environment including the flammable nature as well. The remedy that was provided was similar to the previous stating to park it outside and not fill up the gasoline tank greater than 3/4 full. I expressed that I drive a 2012 Honda Accord and do not have a gasoline leak nor strong odor of this magnitude nor have I ever experienced this before. We live in Las Vegas, NV. I am expected to drive my vehicle less and park it on the street all summer or when temperatures are above 100 deg? She stated, “We live in times where these newer vehicles are not made like the old ones.” I asked, “So is it this model that has the issue?” She replied, “Its the big one right, the CX-90? Yes, the bigger vehicles have this issue.” Is this considered normal to have a valve to release fuel vapors due to high pressures?

It’s now in the shop being torn down for further inspection but it looks to be a cracked cylinder head leak .

The vehicle was brought to Mazda three times for the same brake-related concern. The issue occurred during braking and has not been resolved despite inspections and repair attempts.” If you’re listing each visit, do it like “Visit 1: Customer reported brake noise. Dealer inspected. Visit 2: Same concern returned, vehicle brought back for diagnosis and repair. Visit 3: Brake-related issue reported again. Problem continued.” That keeps it clean and close to the service records. And it at a dealer ship for the 4 time already , and they keep saying it the brakes but now I have to pay for the fix when I was complaining about well under wa

The high beams would turn on by themselves, and no matter what I did, they wouldn't turn off. Each time the high beams turned on, I would have to fiddle with the control stick for a few minutes until the high beams turned off. Sometimes they would turn off for a second and then just turn back on. This is dangerous as it can blind other drivers. This has happened ever since I bought the car a few month ago. On August 11th the control stick broke off while I was trying to turn off the high beams. Now I have no control over the turn signals or the lights. I brought it to the dealer, but they refused to repair it for free. This is a brand new car which is under warranty.

1.5 years after purchasing new my passenger side front door would not open from the inside. Mazda states car is out of warranty at 36837 miles indicating a cable had come disconnected. Approximately 1.5 years later at 59934 miles the front passenger door again would not open from the inside. Mazda states that this door is used frequently (it is not) and after troubleshooting replaced the door handle and lock mechanism on June 22, 2026. Other than having out of pocket expenses of $738 I feel fortunate that I wasn't exposed to a life threatening situation whereby leaving the vehicle through the passenger side was my only option. Searching forums online show that this failure is currently occurring to others. My hope is that Mazda will formally recognize this issue with the passenger side front door before someone is seriously injured.

The Mazda cx5 2026 I purchased has a white film behind both headlights. Mazda refuses to replace headlights stating this is normal. However it is a manufacturing defect. This is a structural problem from outgassing causing a permanent haze on inside of each lens which is considered to be a night visibility hazard. I bought vehicle second week in XXX.Took it back to service dept on XXX. They said no to replacement . Contacted corporate XXX to no avail. Same story. Mazda will no replace even though under full warranty. contacted attorney general and he said to make report here. In process of retaining lawyer because at this point I don’t know what else to do. I expect perfect vehicle for my money plus expect Mazda to be honest and do the right thing. Never had anything like this happen in my life buying a new car. Thank You.
