2019 Mazda CX-9 Complaints

Car coolant warning light came on for a short time 5 min after starting car, then would go off. During severely cold days it would come on then go off once the car was warm. On 2/25/25 the coolant warning light appeared and stayed on. The car made loud rickety noise, as it warmed up. After driving 2 miles the car coolant light turned red and began blinking. An alert appeared saying car over heating. The car was stopped and smoke came out of the car. The car leaked blue/greenish fluid. Overnight the car cooled. The next day the car continued making loud rickety noise driving to dealership. Dealership would not honor extended warranty for coolant leaks at the cylinder. The water pump cracked, with coolant leak also causing the cylinder to crack and leak oil. Dealership is suggesting total engine replacement. The car has gone through its normal servicing with no reported issues of coolant leak or depletion. The engine overheated in a span of 2 miles after being parked for 8 hours. The car...

I was backing out of a parking spot while watching the backup camera when I felt a bump as if I hit something but the camera was showing I have enough space to the cars behind me. It turns out the backup camera image was frozen on the display and I had hit a car parked behind my car. Please investigate and make the manufacturer solve problems with the hardware or the software. Make sure the display shows a warning when the camera fails and the vehicle drives backwards. There may be children behind the car. Shifting into park and then into reverse again caused the camera to work correctly.

2019 CX-9 GT, 30K miles, in August found coolant leaking under the car. This was 5 months past the warranty (but only 30K miles!). After doing research online, I found this is a massively common issue with all engines from several years encompassing 2019, where the coolant leaks due to a cracked cylinder head. There is a TSB from Mazda, which requires replacement of the engine, once the crack is developed. I immediately called Mazda corporate on 8/15/2024 and opened the case with them. They said they can try to assist, but first I have to take the car to the dealer for diagnosis of the problem. Had to wait 2 weeks, then leave the car, they did a full inspection and confirmed cracked cylinder head. Dealer opened up claim with Mazda (which apparently is separate from the case I made when I called the corporate). I had to go back because Mazda warranty dept. was asking the dealer to prove the engine was overheating, which it hasn't yet, because I kept adding coolant, so the engine nev...

My 2019 Mazda CX9 when you turn the steering wheel it makes a clicking noise. I brought car to a mechanic and was told there is a loose bolt in steering column. Mazda has a TSB bulletin on this issue TSB# 06-001/24 dated 01/23/2024. When I brought car to Palisades Mazda two other customers on line with me have the same issue. I looked on internet and found alot of people are having the same issue. Mazda is aware of this problem and it is a defect. Mazda is fixing this problem for cars under warranty but charging customers past warranty to replace the complete steering column to fix a loose bolt,

I have a coolant leak that I have not been able to locate. Despite replacing the radiator, the leak persists. When I contacted the dealer to inquire about estimates for changing the water pump and timing chain, they advised that it would be more cost-effective to replace the entire engine, which would require removing the existing engine at a starting cost of $5,000, with a new engine costing approximately $6,000. They suggested that if I'm already experiencing issues, it might be better to either replace the engine or consider selling the vehicle and purchasing a new one. This response implies that the dealer might be aware of a larger underlying issue and prefers not to address it directly. Experiencing a coolant leak while on the freeway can lead to serious consequences. It can cause the engine to overheat, potentially resulting in significant engine damage and a complete breakdown. This not only poses a safety risk to the driver and passengers but also to other motorists due to th...
