One problem related to check engine light on has been reported for the 2008 BMW 3 Series. The most recently reported issues are listed below.
Was driving on highway going 80 and the car just shut down, was unable to steer, left me and my 9 year old stranded for about 30 minutes untill it started back up, everyday everytime I drive it no matter what the speed it shuts down and have to pray that I don't get hit by a car or am able to glide to safety, very unsafe not knowing when the car will shut down on me, took to mechanic there were no codes no check engine light or anything, therefore couldn't be fixed, something is not right with car, car only started doing this from April 2019 to present,it doesn't matter if I'm on highway, street, stopped has always happened, like I said I don't know when it's going to happen. Im going to get killed one of these days or seriously injured.
