2018 MAZDA CX-5 Complaints

I own a Mazda that I purchased new in 2018. I have kept up with the maintenance to a “T”. I have never abused it. About a month ago I started smelling a strange smell. Like smoke or burnt oil. A couple of weeks later, the engine oil level light came on and the engine was low on oil and that’s when I started seeing that the motor was leaking oil, and I just found out that the engine head cylinder has a crack. I found out that these vehicles have a defect from the factory on this part that cracked, “Engine Head cylinder”. And now to repair it, it is going to cost me around $6,000. The warranty has run out.

Oil leak. Smoke from the engine. Inspected by the local body shop, we were told that the leakage would probably come from cylinder head. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I work for a body shop and we took this seat out in order to replace the frame underneath. While the seat was sitting on the ground, no one near it, the airbag deployed. We have it on video. We have concerns about replacing the seat/airbag if it's going to randomly deploy and potentially injure our technician or the customer. According to Mazda, there are no known recalls related to this and the customer is responsible for buying a new seat and airbag. I see online that other people have said this too, but they were driving the vehicle at the time it randomly deployed. I'm wondering if there are other complaints regarding this/a way for us to get Mazda to replace this since it seems like a part defect.

Many incidents have occurred with this vehicle. First occurrence happened 11/25/21. Attempting to pass another vehicle and the car began slowing down and various warnings came on. Pulled off to the side of the road, turned off the vehicle and restarted without any further incident. This same thing happened 2 times in 12/2021 both time attempting to pass another vehicle. 2nd time in December the check engine light came on. Scheduled to be seen by a mechanic with the earliest appointment on 12/31/21. Mechanic recommended taking to a licensed Mazda mechanic. Appointment was on 01/07/22. They looked at the car and fixed the issue. Can't remember the issue at that time. By 05/2022, check engine light came back on and car would start slowing down and shutting off when attempting to pass another vehicle. If RPMs would go to high, car would do this. Check engine light came back on. Took to Mazda mechanic on 06/17/22. After several troubleshooting fixes, it was determined I needed a new engine as there were parts broken missing or broken. Did not have my car for 13 weeks. Most recently, on 08/13/23, car shut off in a drive through. Towed to mechanic and needed a new camshaft. Picked up my car on 08/21/23 and within 45 minutes, car shut off while driving up a hill. Towed back to mechanic. This time there are electical issues and an ill fiitting pin. Have to take it to a licensed Mazda mechanic. Having to tow it due to how unsafe it is to drive. Reached out to Mazda with my concerns over saftey and waiting to hear back. Very concerned that this will never be resolved and that this is a very unsafe vehicle to drive.

On 7/30/23, I was driving home from church, and was driving on the freeway in the fast lane when my 2018 Mazda Cx-5, that was only 5 years old, with only over 33.2K miles on it, started to stall. Thankfully, it didn't come to a complete stop, but slowed down tremendously, and had at least 5 malfunctioning lights come on all at once. The car wouldn't go over 25 miles afterwards. I was very thankful to make it home safely, but this was very alarming, since I never had any issues with that car, and always kept it very well maintained. For a car that was only 5 years old and had only 33.2K miles on it, to experience such a drastic problem, is very confusing. It was very concerning that the car almost came to a complete stop unexpectedly without any warning ahead of time, especially while driving in the fast lane on a freeway. I also took pictures of the malfunctioning lights that came on right after the incident took place. I had the car towed into the dealer the next day, and they told me that it was unusual that my engine would do that. They said that it needed a tune up earlier than expected. I was told that the 3rd cylinder was misfiring, and also when the engine isn't working properly, everything else in the car would shut down. Now, why would a car that's been very well maintained, with only 33.2k miles on it need a tune-up? And I always kept up with the oil changes on time. I found out that there was an engine recall on these particular models, but I was told by Mazda that my VIN # did not qualify; however, what I experienced, did fit the description of the recall. I've since then, decided to trade in the car, because I was just too afraid to continue driving it after this experience. I am however, very upset that I had to give up a car that I invested a lot of money in and took very good care of, and only had 33.2k Miles on it.

When I turn my car off I get ignition switch and it stalls then my engine come on and off

The contact owns a 2018 Mazda CX-5. The contact stated that while driving approximately 50-55 mph, the sunroof exploded without impact or warning. The sunroof shattered into several small pieces. The glass fell on the driver and she sustained injuries to her body and legs, but medical attention was not provided. The contact called the local dealer but the vehicle was not diagnosed or repaired. The manufacturer was contacted, who referred her to the dealer. The failure mileage was approximately 26,000.

Infotainment system has begun exhibiting phenomenon described as "ghost touch" where options are selected randomly by the system due to touchscreen failure. This happens while the vehicle is moving and creates a significant distraction to the driver, creating a safety hazard for driver, passengers, and other cars on the road. This vehicle has not been inspected by a dealership but internet information indicates it is a known issue but a recall has not been issued from Mazda, which compromises the safety of the vehicle. No warning for incidents. This is an ongoing issue and occurs routinely during daily driving.

Cruise control suddenly ceased operating and I believe that is disabling the automatic collision avoidance system.
