2016 Mazda CX-5

The car engine is eating oil. There were no warning lights on the dash to indicate this. I happened to check the oil, and it was 3 quarts low. This could have caused the engine to malfunction while driving if not caught in time. This started around 70K miles. Coffmans Service in Warminster, PA has confirmed the car was spraying oil on [XXX] and performed a clean combustion chamber with iridium spark plugs, replaced intake manifold gaskets and PCV valve, and ow-20 oil and new filter. I contacted the manufacturer on 10/17/2024 case# [XXX] and it was dismissed. I did read online that this mazda has a problem with eating oil around 70K miles. The problem still is occurring at an extremely low rate. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Catastrophic engine failure. Needs a total engine replacement, regular oil changes. We went to get the oil changed within 1,000 miles of the suggested mileage range and it was “out of oil”. The dealership told us we needed a new engine. It hasn’t been driven and sounds like a helicopter when turned on. We have had regular maintenance on the vehicle, one owner. It started acting up and was trying to stall out on the highway. Then seized up and wouldn’t go over 10mph. It’s totaled and we feel strongly that this is an extension of the current lawsuit covering many years of Mazda models.

My daughter was driving her 2016 CX5 when the coolant temperature warning message displayed on the instrument panel, advising her to pull over immediately. She had just driven on to the expressway, but luckily was still in the right lane and was able to pull over safely. If she had been in any other lane of the busy highway when this occurred it could have been a serious safety issue for my daughter and the other drivers on the highway. I contacted AAA to tow the car to my local mechanic. The service tech reported that they began by plugging their diagnostic tool into the car and they received two engine codes: P111A-00 and P011A, and that a software update must be performed first. I had the car towed to Turnersville Mazda. They said that there would be a $215 per hour diagnostic fee. They found that the thermostat needed to be replaced as it failed to open during engine operation. This service incurred a $397.55 cost. After replacing it they noticed that a milky substance was produced, indicating motor oil mixing with coolant. They recommended replacing the engine due to a crack in the cylinder head at a cost of $10,300. For some reason the service tech elected to replace the spark plugs and update the software AFTER the catastrophic engine issue was discovered, incurring an additional $330 in charges. Prior to this incident there were no issues with the vehicle, no warning lamps or symptoms of any kind.

Car was having trouble with pickup and was making a subtle recurrent noise. Sped up after turning a corner and engine just sputtered out and car came to a complete stop within seconds. The engine light never came on and the engine did not overheat. Car would not turnover to start after that. Car was towed to an independent garage where they stated engine failure. Was then towed to a garage that can handle engine issues where it was declared a total loss and catastrophic engine failure.

The check engine light came on when I was in my way home. This morning when I started my car, the engine reved on its own and then it went to 0. This is super dangerous. The car could have stopped in the middle of the freeway. I had my car towed to a local mechanic. The error code that came up was p0192. Looks like there is a recall for the fuel pump issue for many mazda, yet mine isn’t part of it.

While driving to the airport suddenly all dashboard lights came on and engine "died" during the drive about 50mph. My wife who was driving, was lucky not to get into a crash and steered the car to the side to a full stop . The tow truck driver tried to restart the engine w/o success. The garage determined it is a catastrophic engine failure and need to be replaced. About 2 weeks prior we had an engine warning light. The car was taken to our regular serviced garage and was inspected w/o any issues and light was reset. All routing maintenance has been performed by same garage. There are similar reports on the web about total engine failure of Mazda CX5 during driving!!!
