The contact owns a 2019 Mazda CX-5. The contact stated became aware of engine oil on his driveway. The contact stated that while driving and coming to a stop, there was an abnormal oil burning odor inside the vehicle. The contact stated the check engine warning was illuminated.
I drove my wife to work and noticed that the car was stuttering and had weak acceleration. I parked in my garage and a couple of hours later returned to see a massive oil leak on my driveway, I had to tow the car to the nearest dealership where a cracked cylinder was diagnosed. There was also a terrible burning smell.
I was driving on the highway, at about 65 mph. The engine lost power and the car began to slow down. It did not respond to the accelerator, but the power was still on. I was lucky enough to be able to pull over to the shoulder without colliding, but it was extremely fortunate that no cars were obstructing me at the time.
The contact owns a 2019 Mazda CX-5. The contact stated while driving 40 MPH with the accelerator pedal depressed and shifting from second to third gear, the engine revved up, hesitated, and lost motive power. The contact was able to restart the vehicle. The check engine warning light was illuminated.
1) It happened last week on 8/30, when I drove back home after work at night. After I parked my vehicle at the driveway and I had noticed there's smoke going into the cabin through the vent. The smell was very bad, it smells like burning rubber/plastic type.
