Driving on the highway and engine stalled on me and wouldnt go. So I rolled over to the side of the highway to pull over. When I stop the car, I see smoke coming from under dash board and under hood. So I get out real fast and open hood. I look down in front of the engine and the engine is on fire. I poured some water on it but did not put it out. Called 911. And backed away. Fire put its self out before 911 got there. Had it towed to Firestone. In examination. They said engine piston blew a hole on the side of the engine. I just bought the car used and had it for 4 months when this happened. Now I am stuck paying for a car that is sitting in my driveway because it is in operable. I cannot afford $10000 for another motor to be installed, which was what I was quoted.

Engine problem

- Philadelphia, PA, USA

Motor started knocking louder and louder at 85,000 miles. Brought vehicle to a GM dealer where they replaced; timing chain, balance chain, tensioner, and valves. GM only claims responsibility for the timing chain, though that part breaking caused far more damage to the motor. GM has knowingly put and kept out their bad 4-cylinder ecotech motors from 2010-2013. Their class action lawsuit stipulations disqualify most vehicles that are affected. My vehicle is currently broken down due to the same issue, I can't rely on the motor to get me where I'm going without dying at a stop sign or running completely out of oil 2,000 miles after having an oil change. While breaking on a highway my motor will rev up, as if it's trying to accelerate while I'm trying to slow down.

Multiple times my GMC stalls while in movement. Does it when I am making turns driving slow speeds or backing up. Multiple times it has resulted in my vehicle almost being hit. Big problem I am having as well is that oil seems to burn fast. I get my oil changes regularly but have to go back into shop between oil changes for them to put more oil in as its burning out so quickly. I am not leaking oil at all!! these two things have been a constant problem being a mom I am scared to have M uh kids in the car that it may malfunction while they are in it and result in an accident. Recalls should be in place to fix these problems as they are serious problems.

My car shut off once while I was in idle at a red light and second time when I was backing up into a parking spot some one who was driving opposite me could have hit me when the car abruptly stopped. Luckily they were going very slow and stopped when my car stopped. The engine shuts off as well as the lights on the dash but when you put it in park and start it up again the engine starts back up and no check engine lights appear. Can you please look into this?
