MAZDA Complaints

The vehicle has a cracked cylinder head as a result of stress put on the block from a bad exhaust manifold design. This is a known issue to Mazda and service bulletin was sent out to all their dealerships in 2021. Mazda only offered to pay a very small portion of the repair and puts the rest of the cost on the customer. Luckily I caught the issue early but this could have been dangerous if the car overheated and the engine failed on the highway. There are countless other stories of consumers having the same issue with the CX-9 and CX-5 of the same year. Many resulting in engine failure.

The car does not turn off when I put it in park and push the ON/OFF button. I have to start and turn off multiple times and jiggle the gear shift multiple times before it turns off. Sometimes even that doesn't work. Because the car doesn't completely turn off, it runs the battery down which leaves me dangerously stranded. The car is available for inspection. My safety is put at risk because it drains the battery and leaves me stranded, sometimes in dangerous situations unable to get assistance. I have not taken it to a dealer or service center but have seen MULTIPLE reports of other owners of this same vehicle having the same problem. The problem has not been inspected by the manufacturer, police, insurance representatives or others. There were no warning lamps, messages, or other symptoms before the problems started. It started a while ago but I'm not certain of the date. The messages I've read online of it happening to others are from several years ago, so this seems to be a problem that has been ongoing for several years that Mazda has failed to address.

2014 Mazda CX5 will not turn off, keeps telling me to put it in park - then it tells me key fob battery low, which it is not. I have to turn the car on/off, on/off, on/off to get it to shut off.

The contact owns a 2010 Mazda Mazda6 . The contact stated while driving approximately 25 mph and drove over a bump and lost control of the vehicle and crashed into another vehicle. The contact stated the disc off warning light was illuminated. The contact stated no one was injured nor sought medical attention. A police report was not filed. The vehicle was not drivable. The contact was towed to her residence and then to a local dealer, where it was diagnosed with the rear structure was corroded and needed to be replaced. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 180,000. The contact stated that the dealership deemed the vehicle unsafe to bring to the shop and therefore did not perform the necessary repairs in the recall. The dealer notified the contact about that as well as the manufacturer. The contact must arrange a way to tow the vehicle off of their lot.

Experiencing a known excessive oil consumption issue. Low engine oil warning light came on and upon checking, oil was low. This occured at 4000 to 4200 miles. It occured again about 4000 miles later and again at a similar interval. I notified the dealer and scheduled a repair date but I am concerned of other possible damage that may have already occured due to this issue. An oxygen sensor needs to be replaced and is most likely due to the engine malfunction. The cause of the consumption is said to be damage to the valve seals on the exhaust side.

I have only 20k miles on my car and my engine's oil consumption has suddenly jumped. Despite checking my oil frequently, my oil becomes low and the oil warning light comes on. The oil warning light last came on while I was traveling on a snowy 2 lane canyon road while leaving a ski resort in Utah. I had to immediately stop my car on a busy, icy road to add more oil. I almost got hit by a sliding car and killed. I went to the dealer with this problem and they told me they could not help me unless my oil light was on. Driving with a oil light on in the winter is dangerous. The engine could seize and leave me stranded on the side of the road. The dealership said to run the car low on oil with the oil light on and them come in.

Brakes make a jerking sound decelerating from 40 miles an hour or from coming off a freeway ramp. After two trips to the dealership, the jerking sound still persists, the dealership had mentioned it was either the ball bearings or the brake pads were worn out, but somehow the noise is still there. The vehicle still makes stop safely, but we feel that if this is not resolved that this may become a greater safety issue down the road.

I was driving my car on the highway. The car automatically deployed the emergency braking system with no objects in front of the car. The car automatically braked then flashed the brake warning indicator. Car mad itself come to a complete stop. I began researching and found that others have had issues with “phantom braking” when the car has collision avoidance technology. This needs to be seriously investigated as it is a safety hazard.

I own a 2018 Mazda CX – 9 with only 53,300 miles. I noticed something was wrong with my engine and had no idea what the issue was. My car would not shut off immediately when I turned it off and the fan was on super high speed. The day before my appointment with my mechanic, the engine light turned on. I was stuck in a parking lot and a friend suggested I use his car to go buy coolant just in case it was needed. Sure enough, I was completely out of coolant. When my mechanic inspected the car he told me I had a coolant leak and suggested I take it to the dealer as they would know immediately what the problem was. I started researching to see if this was a defect and sure enough, Mazda has been aware of the defect with the cylinder head (TSB) not supporting the turbo of the engine causing it to crack and mix with the engine oil in various models for years, yet continue to sell cars with this known defect. I understand that it may not be life threatening yet! But it could have been should my engine had blown while I was on the freeway causing a horrific accident. How are they allowed to continue manufacturing and sell cars with a known issue for years and not even be reuqired to make a recall to have the part replaced with a stronger one? This is issue is happening to 100's of customers worldwide. This is something that should be investigated.

Infotainment screen has spider cracking from faulty screen when manufactured. Open TSB stating this and Mazda refuses to replace under warranty after 5 months of owning vehicle, spider cracks got worse this year. When i got more spider cracks i contacted mazda support since the first time I contacted a local dealer. Mazda support denied replacement because “ i do not get my car serviced through mazda”, this screen issue has nothing to do with a car being serviced. This is a safety issue as you can not see parts of the screen and will only get worse and make the whole screen inoperable when using navigation.
