Cylinder Head has failed at 53,000 miles. Mazda has a technical service bulletin acknowledging that this is a common occurrence with this part. They have an extended warranty for the turbo engine but not for the standard engine. Looking through online forums, there are hundreds of not thousands of these issues for this model year and engine. Mazda has clearly acknowledged there is an issue and should repair these manufacturing defects that are not normal wear and tear items.

I purchased a brand new Mazda CX5 in 2020 that now has 46,000 miles on it. It is experiencing the known “ghost touch” issue in which the entertainment system and screen displayed in the center of the dashboard turns itself off and on, changes settings, shuts off navigation while driving, changes the radio from FM to AM, changes the time zone, drops hand free phone calls, initiatives hands free phone calls, does not allow me to control the volume, freezes, and more, while driving without me touching the system or even when it isn’t on. It is incredibly disruptive and distracting when driving and is a major safety problem. There was a class action lawsuit for this issue for 2016-2020 Mazda CX5s that expired in 2025 in which Mazda was required to pay up to $1750 for repairs. I was not having this issue at that time and have been told Mazda will only pay a portion to correct this issue. Considering how popular this vehicle is and the likelihood of this being cost prohibitive for many people to pay for themselves this has the potential to be a major safety problem throughout the country.

While driving on the highway in traffic, I was applying the brakes (slowly and smoothly) and moving with the flow of traffic when the SBS system activated the brakes harshly and slammed me to a stop without reason. In addition to throwing me forward against my seatbelt, it also resulted in the car behind me rear-ending me. I did not hit the car ahead of me, since I was far enough behind them BEFORE the smart brake support engaged, but the feature caused an accident that could have been avoided.

The steering column in this car has a known defect in the steering column nut resulting in knocking/rattling/clunking. Mazda is aware of this issue and has redesigned the steering column and issued multiple TSBs for specific models, years, and even VINs. Mazda is not classifying this a a safety issue to avoid recall but if the part is to fail it can result in loss of vehicle control and a crash. The steering column is main component necessary to have control over the car and the direction it travels. I've called my dealership and Mazda corporate who both refuse to fix the issue even though my car is under an extended warranty. TSB 06-001/24 previous TSB 06-004/23.

The front seats, both electric and manual powered are rocking back and forth. Upon acceleration both seats will slightly rock backwards and then upon applying the brakes they will rock forward. It's almost like whatever is holding the seats still has a defected part or a defect somewhere else. This concerns me as a safety issue, if something were to happen and if I got into an accident, aren't the seats supposed to be secured and not have any slack or rocking in them? This has happened before on my driver side seat when I had a mazda service technician look at it he confirmed it needed to be repaired. For a whole replacement seat was estimated around $4,000.00. I was fortunate at the time to where my bumper to bumper warranty helped cover some of the cost, Mazda agreed to pay for the "parts" to fix the issue and I paid for the labor, only because I was slightly over the 36,000 mile warranty that comes with Mazda. Since the repair I was told it wasnt going to be 100% and I would still have some rocking but it wasnt as bad, that occurred around the year 2022. Now, when I have a passenger the same thing occurs. Unfortunately, I'm no longer in my bumper to bumper warranty and quite frankly this seems like a safety risk that Mazda is aware of.
