I took our vehicle into Mazda due to a coolant leak that could not be located. It had my wife stranded due to the vehicle overheating. Everything lined up with CSP11. The dealership is now stating that the vehicle has a blown gasket and needs an engine replacement. This is the issue covered by CSP11 except that the crack is in the wrong location. They haven't found the Crack but are denying the warranty due to the covered location not being the source. The vehicle only has 93000 miles on it.

My infotainment screen goes black 10-12 times a year, and therefore I lose access to my backup cameras. I have to turn the car off, and then back on, in order for the screen to function again. This has been happening for the full 8 years I have owned the car. I also have video of this happening, but the file is too large to attach so including photo only.

I was driving the vehicle on the highway when the vehicle started to overheat, lights started blinking, the car was smoking, losing power and acceleration. This car has a recall on the cyclindwr head which when cracks causing the car to loose coolant and oil. If it cracks while you’re driving especially on the highway the car will immediately loose coolant and oil thus causing a very dangerous driving condition. There was no indicator prior to the failure that there was anything wrong with the car. No check engine lights, no coolant lights nothing. Prior to this happening I smelled coolant in the car cabin , took it to my mechanic who tested the coolant system and found no leak. At the time he was unaware of the known issue these cars have with the cylinder head. The problem has been confirmed by Mazda and they notified me within the month of March of the problem and the extended warranty to replace the known manufacturer defect cylinder head. The Mazda dealer now has my car and acknowledges the cracked cylinder head caused the problem but said because I didn’t immediately stop on the highway and kept driving until I got to a safe location I was negligent and are refusing to fix the car which now has a blown engine, etc. it is available for inspection now at the Mazda dealer. My safety was put at risk because I could have died on the highway if the car completely stopped working, it was dangerous driving it when it first started happening because it started out of nowhere the car was fine I was driving 50+ mph and it started smoking, overheating etc. I could have also killed someone else. It is a disgrace that not only they won’t fix my car they want to say they won’t because I’m negligent? I drive my kids to and from school everyday do you think I’m going to risk their safety in an unsafe car? They should not only fix the car but compensate me for putting mine and my children’s lives at risk. A complete disgrace.

My 2017 Mazda CX9 Signature Edition started leaking coolant from the engine near the firewall. I had a Mazda dealer investigate. They tell me the cylinder head is cracked and the entire engine needs replaced. This appears to be a common problem due to a design flaw and there is a Mazda service bulletin on it. I have found talk of a class action suit online because Mazda is not standing behind their product. I only have 88k miles on this car

My 2017 Mazda Cx9 was stalling and jerking while driving almost causing an accident but glad I was able to drive it home without causing an accident. Took the car to the dealership and was advised that it needs a new engine due to coolant leak. The coolant was going inside the vehicle.
