What owners wrote
“Truck cut out going across the road almost got hit due to the vehicle stalling then about a mile down the road the check engine light came on parked it took it to my mechanic and after the incident it was throwing a cylinder misfire code. Cylinder one when the mechanic got in there was completely shot and I had to have a new motor. No warning no lights could have potentially caused a major accident.”

Should you keep driving it?
This page can't tell you that. 0 of 30 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
