The contact was able to restart the vehicle and continue driving. The contact stated that on several occasions, while the vehicle was jerking at a complete stop, the contact shifted to park(P) to prevent the vehicle from stalling. The vehicle was taken to an independent mechanic, where it was diagnosed and determined that the fuel pump was leaking fuel into the oil gasket. The mechanic replaced the mass air flow sensor, the oil gasket, the fuel pump, the catalytic converter, and the starter; however, the failure recurred while driving.

My Terrain just started stalling. And it happens a few times a day. This is not safe. I had my daughters with me in their car seats, as I pulled out from a stop sign it just died. I couldnt steer or anything. People coming down the road and I am stuck In the middle of a street until I could put it in park and restart. And then it happens again when in reverse. I thought I accidentally had it in neutral. I restarted it and thought it was fine. It gave a little chugging when I hit the gas pedal but all was fine until I stopped to pull into a parking spot and tried to reverse again to straighten my car. I turned it back on, then it was good enough to get out. when I went back to my car it stalled like 4 times when trying to simply leave the parking lot.

Engine lost power suddenly while driving. No warning. Fuel pressure slowed to where vehicle no longer moved forward. Again. No warning. Timing chain slipped TWICE and destroyed engine without warning. “Engine power lost” appeared on dash from driving without warning or incident. Excessive oil consumption without warning. Smoking engine even though had regular oil changes. Engine had been inspected by dealership and allegedly had no issues. Car never smoked but did after second time of timing chain slipping/breaking. This issue has happened repeatedly to many drivers who own these vehicles. Had a difficult time stopping after engine and total power failure without warning.

My vehicle began to sputter and stalled as I decelerated and approached an intersection without any warning. I stopped and restarted the car and the engine light came on. I was within a mile of dealership, called them and took it in. They estimate $1,200 for repair. I searched known issues with this make and model and I am not alone with this problem. I am concerned that this may happen again which could be very dangerous. I do not see any recalls but there are numerous issues stating this same issue on a simple search of none issues for this SUV.

My vehicle is under 60k miles and one day I woke up went to drive it my engine light came on and my vehicle started to sputter and try to die out while driving in a school zone going 20 MPH. Then after making it to my destination I placed the vehicle in reverse and it died out on me. I started it right back up it died as soon as it hit reverse again. Finally I was able to start it and coast backwards then place it in drive. I had recently gotten gas and thought maybe something was wrong with the gas but im seeing this is a problem for more people than just me. So disappointing bc it is a lease and my lease is up in one month so now im held liable to fix a problem that I feel like should be a recall. I've always stayed up on my oil changes, and maintenance and im very disappointed in the quality of this vehicle.
