2 weeks ago I noticed an oil leak 2019 cx5 . Riley Mazda of Stamford check and found a cracked on the cylinder head. The cylinder head needs to be replaced cost around $5000. luckily we noticed the leak while car was park. Imagine if the car was on the road. Dangerous things could have happened. Mazda is aware of this situation years ago. A technician Service Bulletin was released by Mazda in 2019/2021 to all dealerships technicians repair guideline and why the cylinder cracks. On the Mazda bulletin it clearly explained a design defect resulting cylinder head cracks. Also Mazda failed to warn cx5 owners about the dangerous situation. On top of everything Mazda refuse to pay the Defect cracked cylinder head that cost around $5000 . I email mazda Numerous times and decline any goodwill repair . Reason is out of warranty. Most Cylinder heads past 200,000 mile mark. Not unless your engine overheats but it not. Mazda should reimburse us owner who paid the repair cost

Smoke started coming from the front end of the car so I brought my car into the Boniface Heirs Mazda dealership for a diagnostic. I was informed by the mechanic that my car has a factory defect and the head of the engine was welded wrong.

Smoke started coming from the front end of the car so I brought my car into the Boniface Heirs Mazda dealership for a diagnostic. I was informed by the mechanic that my car has a factory defect and the head of the engine was welded wrong. Apparently this is a known factory defect in the 2018-2019 Mazda CX-5s as I have seen other reports for the same issue. I reached out to Mazda corporate to see if they could help with “after warranty assistance” since this was a manufacturers issue and I do everything to maintain my car properly. They denied any help and do not plan on recalling the part. I had no warning lights just smoke pouring from the font of my car. I do not understand how this is not considered a safety issue. I’m lucky my car didn’t catch on fire. I now have to decide between spending $5000 to fix the engine head or to sell my car and find a new one.

While driving down the road my Mazda CX-5 continues to just stall and the engine light turns on and the safety features turn off. I was driving down a road in town and the engine started stalling as I came to a red light and slowed the engine shut off and I was almost hit from behind. It took several attempts at starting before the car would start. This has now happened for the past 3 days and is happening more and more frequently. I do not have any other means of transportation and after attempting to get the dealership to check due to the recalls on the Mazda CX-5 for fuel pump failure and the mechanic saying it appears the fuel pump is bad the dealership refuses to attempt any repair because the VIN is not listed in the recall at this time. This is a severe safety problem because if it stalls in traffic I will be in an accident as I have no ability to maneuver the vehicle when it stalls to get out of the way of vehicles approaching. If this issue isn't resolved it is going to cause injury to myself or others. People have had to swerve into the path of other vehicles to keep from hitting me when it stalls, which is eventually going to result in harm to others and/or myself and family.

The computer monitor on the vehicle seems to have a mind of its own. After talking with the service rep they actually have a name for it because it is happening to many owners "Ghost Touching. The car tends to call people on your contact list automatically, change radio stations, move from settings all on its own. I feel it is dangerous because it will all of a sudden call someone and then you are trying to stop it and it does not disconnect and your focus is now taken off of the road and driving. Even if you try to turn the monitor off it turns on by itself. I was told there is no way to disconnect it and I would have to pay to have it fixed on a car that is only a couple years old. They know this is happening quite a bit, Mazda corporate would not do anything and I think it should be a recall issue before someone gets in an accident. This happens many times in one driving day.
