2021 MAZDA CX-5 Complaints

The engine low oil light comes on every ~3000 miles when Mazda recommends an oil change at every 7,500 miles. For some reason this engine eats oil and has consistently reproduced the check engine light every 3k miles. Mazda hasn't issued an official recall but has published a technical service bulletin.

Engine burns excess oil and must be topped off before service is due. The dealership acknowledges this is a problem on all 2021 Mazda turbo engines. Mazda has no fix. The first time occurred when I was driving in the country in July 2022 and the check oil light came on. Today, March 3, my check oil light lit up. I am not due for service for another 1800 miles. I have read it is a valve stem problem which causes oil to leak into the engine which can cause the car to stall among other issues such as unnecessary wear and tear. A class action suit has been filed in California (Heinz vs Mazda) November 15, 2022.

The car is consuming excessive engine oil. Between 3000-4000 miles the low engine oil light comes on. I was on the highway and had to pull over. I was told we don’t need oil change until 5000 miles. Not feeling safe to drive long distance. Dealership acknowledged seal is causing the leaks, but said Mazda won’t cover the cost unless check engine light is on. Also the break pads are moving slightly when breaking, dealership said it’s normal due to break pads are moving back and forth when breaking. However, I can hear the breaks clicking.

My car is a 2021 CX-5, Turboed AWD vehicle. It keeps consuming oil. I took it to the dealership, Sandy Sansing Mazda in Pensacola, where I purchased the car. The technicians informed me that these models are known to consume oil. They did not tell me that when I bought it in September of 2022! They had a technical service bulletin, which works as a policy for the company, with a range of VIN numbers that indicated the vehicles with those VIN numbers are likely to have a manufacturing defect that allows oil to leak into the combustion chamber. My car's VIN number falls within that range. While I purchased this vehicle to drive long distances, including to see and care for my mother in NC, who was recently diagnosed with terminal brain cancer, and to Alaska from FL, my newish (pre-certified) car runs out of oil quickly. It must be causing internal damage (plugs, wires, exhaust, and the cylinders). When I asked the Mazda techs to fix the issue, they informed me they would not uphold the warranty, because I put oil in the vehicle. I was 400 miles away from home on a trip, on a Sunday, when a light in my car came on that indicated the car was low on oil. Why wouldn't I put oil in it? It is not safe to drive a vehicle with no oil, as it could cause the engine to stop working. One time, my oil pump went out in a 2002 Tacoma, and my camshaft welded itself together, or to other parts of the engine, at 70 mph down a highway. I lost power steering, power brakes, power in general. The timing belt was instantly shredded. It's not safe to drive cars that consume oil so rapidly between recommended changes. Mazda would not uphold their warranty responsibly, and they have known about the defect for some time, yet they are still selling cars that are unsafe to drive.

I experienced a sudden unintended acceleration incident. I pulled into my driveway and stopped the vehicle with my foot firmly on the brake since my driveway is sloped. I pushed the garage door opener remote when suddenly the vehicle accelerated and shot forward hitting the garage door. There was no brake action and all backup systems failed. There was no Automatic Emergency Braking or Forward Collision Warning. There were no warning lights displayed. No airbags were deployed. If the garage door had been open, the vehicle would have hit a concrete wall in the garage. The vehicle was taken to the Mazda dealership and a full circle inspection and diagnostic check. Mazda found no codes and everything was working as designed in vehicle.

Low engine oil light appeared despite standard maintenance service and oil change at Mazda dealer the prior month. Service technician confirmed oil was low by 1 and 3/4 quarts and added oil. Mazda dealership advised there is a service bulletin for my vehicle with this problem dating back to 2021, and that the problem is likely due to a faulty valve, but that they have no planned fix available. I am concerned about the long-term damage of engine oil continually leaking into the combustion chamber. Mazda should be asked to fix this for car owners, not simply top off our oil each time that it leaks.

It appears that my car has the check oil level light coming on at approximately 3000 to 4000 miles after an oil change. This seems like a safety issue to me because a brand new car should not be burning a quart of oil at this interval.

oil consumption on a 2021 Turbo CX-5. problem has been reproduced and confirmed by dealer. warning lights twice. first time told it was normal. happened twice. only on my third maintenance oil change was it acknowledged. had to do a lot of research on my own. caused enormous stress to existing mental health issues. would not have even been addressed had i not stated the issue.

Engine is either burning or leaking oil. The low oil light flashed after a 2hr highway trip (traveling to my parent's house for Christmas with my wife), low oil was confirmed the following day via dipstick. Oil was changed at the dealership about 4 months ago, mileage is under 24k miles. Looks to be related to this service bulletin, which still does not appear to have a fix or recall associated with it. Mazda Oil Consumption TSB Turbo Engines Components: ENGINE AND ENGINE COOLING, TIRES, ELECTRICAL SYSTEM NHTSA ID Number: 10202685 Manufacturer Communication Number: 01-012-21-3832 5 Affected Products Vehicles MAKE MODEL YEAR MAZDA CX-30 2021 MAZDA CX-5 2021 MAZDA CX-9 2021 MAZDA MAZDA3 2021 MAZDA MAZDA6 2021 Summary Some vehicles may have a LOW ENGINE OIL LEVEL warning message and a CHECK ENGINE light illuminated in the instrument cluster, along with DTC P250F:00 stored in memory. DTC P250F:00 - Engine oil level signal: engine oil level low. Upon inspecting the engine oil level, the level is found to be low and there doesn't appear to be any trace of oil leakage in the engine compartment. This concern usually occurs when the mileage reaches approximately 3,100 - 4,700 miles (5,000 - 7,500km) and may also occur again after replacing or topping off the engine oil. The root cause of this concern has not been identified yet, therefore a repair procedure will be announced at a later date. Since this issue has been reported after a valve stem seal modification, it is very likely that valve stem seal damage is causing oil to leak into the combustion chamber.

The car has a key fob which is supposed to automatically lock the car when you walk away (and unlock when you press a button on the door handle when the fob is in close proximity). My car sometimes does not lock when I walk away. They encourage relying on this method, and so sometimes I return to my car, and it is unlocked. I consider this a safety issue both from a personal safety standpoint and from a car theft/ interior item theft standpoint. I have tried discussing this with the dealership repair department, but they mansplain to me that you have to walk FAR away for the lock to activate (which is actually directly contrary to the owner's manual for this model, as well as my personal experience).
