2020 Mazda CX-5 Engine

I noticed an oil leak. I had it diagnosed and its a crack in the cylinder head, right above the exhaust manifold. This is known issue for Mazda's online. There is oil spilling everywhere. The oil burns off as it is driving. Smoke fills my car.

Engine developed multiple oil leaks from oil seal and timing cover. The leaks could result in engine failure and endanger driver and/or passengers. No warning lights activated, was found at routine oil change. Defect was reported to manufacturer, but warranty had expired, and they refused accept responsibility. Research revealed this vehicle is known to have this defect.

Low oil light came on at 52,764 miles, 300 miles before the next oil change on the manufacturer-recommended 7500 mile schedule. I've switched to a 5000 mile oil change schedule and will be monitoring oil level going forward for excessive oil consumption. I have always done oil changes every 7500 miles and have followed all other maintenance prescribed in the manual.

The engine of this vehicle has been leaking from different areas consistently. The first leak was the timing cover gasket not properly sealing from manufacture. The dealership covered this under warranty without push back. I then identified a weep from the oil pan gasket during a normal oil change interval. This gasket leak was again from manufacture. I had watched this leak and it seemed to be getting worse over changes and evolved beyond a weep. I also found oil leaking onto one of the spark plugs when changed around 56K miles. I brought it to the dealership and received much push back, conducted oil consumption test for a visible leak, and then placed dye in the oil. It was identified as the oil pan gasket leaking. After much hesitation I eventually was able to get this "repaired" by the dealership at 57K miles. We are now nearly crossing 65K miles and a new leak has presented, enough to cause the low oil light to illuminate and pooling of oil on the access cover. I have yet to identify the source but I am again bringing this to the dealer. Safety concern is that my wife and toddler were an hour away from home on the side of the highway when this light illuminated and had to stop on the side of the road in the cold weather and turn the car off. They could be pulled over in unsafe areas or even be stranded in the cold - or risk seizing the engine to stay warm.

For some reason this vehicle will make a whoop sound after driving it for a little then idle, either at a stop light or sitting in a parking lot. The first time we heard it we thought that there was a police vehicle in the area. We took it to Mazda dealership, and they didn't what why it was making that sound. The vehicle has less than 25K miles. We are not sure if it could be a big safety issue or not but would like Mazda to look into this. There are no warning lights or signs to know when it's coming. The Mazda dealership in our area has no clue and it is annoying hearing this whoop sound.

At mileage of 24,993 and on April 24, 2022 my oil light came on, creating a very unsafe situation for myself and my young son, nearly stranding us on a very isolated road after dark. My vehicle has regular maintenance at the dealer and was not due for an oil change until 25,378 miles or June 13, 2022. About 30 miles prior to the engine oil light coming on, my car indicated that an Oil Change was due (prematurely). I added oil to be able to drive it to the dealer who has not verified any issues.

The contact owns a 2020 Mazda CX-5. The contact stated that while the brake pedal was depressed stopped at a light, he noticed that the vehicle moved forward and the RPM was fluctuating from 600-1,000. No warning light was illuminated. The vehicle was taken to the dealer where the failure was duplicated; however, the vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 9,000.

Currently own a 2020 Mazda CX 5 Touring, after coming from work I parked in my driveway and proceeded to turn off the car. When i was walking away i could hear the engine still Running. I went back and turned on the car and turned it back off, again i could still hear the engine still running. I went back and got inside and took the car for a 5 minute drive, then came back to my drive way and placed the car on park and then proceeded to turn off the car. I got out and went to the front of the vehicle to see if the engine was running, this time the engine did turn off.
