“- Coolant leak at cylinder head and turbo at only 63,000 miles. - Safety issue because no warning lamps or messages appeared and potential for car to overheat without coolant circulating in the system. Car could breakdown at worst time and location. Leaking coolant onto exhaust created potential for fire. - Problem has not been confirmed by dealer yet. Appointment is upcoming. - Symptoms of the problem were leaking coolant on ground, low coolant level, heater not working properly. - First appeared 1/29/2026.”Owner report · Engine · Jan 2026
“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.”Owner report · Back Over Prevention · Oct 2024
“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,”Owner report · Steering · Sep 2024

“2019 Mazda CX-9 Coolant Leak. 1st warning light just discovered on June 10, 2024. Dealership quoted not under warranty and will cost $14,000 to replace engine. Mazda has an open TSB Technical Service Bulletin for this and many other Mazda's with the same engine- TSB-Coolant Leaks at Cylinder Heads, Bulletin # - 01-013/21 issued 10/15/21 (CRACKED CYLINDER HEADS). Need Mazda to stand by their product and remedy impacted owners.”Owner report · Engine · Jun 2024
“Started with rough idle then got overheating msg on dashboard. After the diagnostics they found cracked cylinder head and quoted $6000 for replacement. Called Mazda USA and they denied our claim. Car is under 5yrs old & around 74k. While working on the car they noticed the turbo needed it to be rebuilt. Another $2k. There is TSB out for this and it's a known problem, lot of others having/had same issues. Never had a car that needed an engine replacement even before car is paid off.”Owner report · Engine · May 2024
“In June of 2022, Mazda issued a TSB for an engine flaw that cause coolant to leak in to the engine and significant overheating occurred. This overheating causes the head to warp. The TSB states that the only repair for this is a newer model engine. This happened to my Mazda CX9 and quite a few more. There are class action suits currently ongoing. Mazda never made its owners aware of the TSB. The car can shut down on the highway which is dangerous to all.”Owner report · Engine · May 2024
“My car has a 60/40 split adjustable-type second-row seat and the driver side of the 60/40 split-bench second row seat has been sliding forward during braking despite being seemingly locked in place. Apparently, a similar issue was the subject of a safety recall for 2020/2021 Mazda CX-9s (5221I). I have spoken with Mazda and they are not offering to replace the seat as part of the recall since my car is a 2019. While I understand their position, the issue appears to be the exact same one described in the recall of the 2020/2021 models.”Owner report · Seats · Feb 2024
“The contact's husband owns a 2019 Mazda CX-9. The contact stated that while the vehicle was at the dealer for a diagnostic test, she was informed that the head gasket was cracked, and fluids were leaking into the engine. The vehicle was not repaired due to the cost. Additionally, the message "Excessive Engine Temperature - Engine Output Will be Limited" was displayed. The vehicle was not included in NHTSA Campaign Number: 21V875000 (Fuel System, Gasoline). The manufacturer was made aware of the failure. The failure mileage was approximately 62,756.”Owner report · Fuel System, Gasoline · Dec 2023
“The car has only 41k miles on it and the engine warning light came on. I had the car towed to Mazda and now it won't start and it needs a new engine. (Which is on back order for months). It is covered under the powertrain warranty but does me no good if I'm without a vehicle, and making car payments on a vehicle that isn't running.”Owner report · Engine · Nov 2023
“My 2019 Mazda CX-9 Signature has developed a coolant leak at the back side of the engine that is consistent with Mazda TSB 01-013/21. Coolant leaks down onto the oil filter and the exhaust where it's burned off. Currently, I can drive the vehicle, but I need to refill the radiator and coolant reservoir. I'm concerned about this developing into a catastrophic leak that could seize the engine or cause a fire from contact with the exhaust. This vehicle is still under the warranty period of 5 years/60K miles. I will initially contact the dealer regarding this issue.”Owner report · Engine · May 2023
