MAZDA Complaints

The engine developed a sudden coolant leak on the rear of the engine. A warning comes up stating that the car could overheat and lose power. After a few minutes and no sign of the car overheating, the car loses power and slows down on its own. The car has not yet been seen by the dealer or a repair shop due to no appointments available. Mazda USA has issued a TSB stating the issue with the engine and they state that a design flaw causes the cylinder head to crack because of the external forces from the exhaust system over bumps. The failure appeared all of a sudden with no warning lights or indications, it just started leaking a small amount of coolant one day. Now I'm waiting for Mazda USA to tell us how they are going to remedy this issue and provide assistance. According to their TSB this affects three different vehicle models with the same 2.5L turbo engine built from 2016 to 2020.

FRONT PASSENGER SEAT CAUGHT FIRE WHEN SEAT WARMERS WERE ON. I WAS TRAVELLING IN A RURAL AREA IN ALASKA WHEN I HAD TO STOP BECAUSE MY PASSENGER CAUGHT FIRE ON HER JACKET.

Just before taking the vehicle for a second oil change at a total of 11,664 miles or approximately 7,000 miles between changes, I noticed that the oil level was at least 1 quart below normal. I added oil to make sure that it was above the add point on the dipstick. I researched and found several other complaints about other 2021 Mazda turbo engines with the same complaint. I'm concerned that this excessive use of oil will damage the internal parts of the engine.

For the last 2 yrs the screen and radio volume and turned up loudly on it's on while driving and causes a severe distraction. Also the channels change on it's own and beep. The screen changes from light to dark mode on it's own and the Bluetooth cuts out while I'm on the phone or it calls someone on my contact list on it's own. It's caused me to be distracted and almost have accidents because it doesn't stop. This is an ongoing problem with Mazda owners and should be recalled due to safety concerns There was a recall on older models with the same type of issue. . It's gotten much worse lately and I've just taken it to the Mazda dealer. They call a Ghost touch and they said Mazda is aware of the problem. There has also been reports on the BBB website about similiar issues. I called Mazda and they opened a case on it. The Case # is 00104322. The Mazda dealer said it would cost over $600 to fix and the screen needs to be replaced

I drive a 2018 Mazda CX5. My "infotainment system" which contains radio, phone, and GPS controls began making random unprompted selections while I would not touch it. This is an ongoing issue. The name for this issue is called "ghost touch" While the Mazda system "locks" the touch screen while the car is moving, the issue continues as soon as you come to a red traffic light. Without putting the car in park, the touch screen reactivates and the issue proceeds. This is a safety issue as it can cause distractions while driving such as sudden significant changes in music volume and it can call a random person if your phone is connected to Bluetooth. Regardless of if the car is moving or not, this causes a driver to take their focus away from the road. From a quick google search, this is a common issue. Mazda is aware of this common issue, and in fact extended a warranty to correct it in 2014-2016 Mazda 3's. However, I called Mazda USA today and they stated that it would have to be paid out of pocket for my car.

Lane keeping assistance does not prevent the vehicle from departing the lane nor does it provide corrective steering. LKA is fully activated and vehicle travelling over 45 mph on highway with clearly marked lanes; vehicle drifted across three lanes with zero corrective action from LKA.

Driving down the freeway smoke started coming out of the hood of the car and into the cabin, no warnings or warning lights of any kind, got the car to the Mazda dealer to be inspected. The dealer told me it was 5 months out of warranty and would not be covered its a cracked cylinder head and oil had dripped/leaked onto the manifold causing the smoke. No smoke was coming from the exhaust so the crack only leaked oil to the outside of the cylinder head. There is no oil in my driveway so it happened that day on the road. This is a manufacturing error that Mazda won't take responsibility for.

Both headlamp lights have water on it (Condensation ocurring on both headlamps) Please verify if this situation could be considered a safety hazard.

Brakes are very poor, car lurches forward at stop lights and you have to stomp the brake pedal to prevent running into the car in front of you.

UNKNOWN cause for short battery life. The battery has been changed 4-5 times since 2020 with a brand new battery. The alternator has been checked and is fine. The dealership is going to check my vehicle again but this is an issue for multiple people with the same vehicle model.
