On an early cold morning, I crank my car and after it started I noticed that my check engine light came on; it stalled out and I had to restart it. This car has been in and out of the repair shop (BMW) within the last year approximately four times. The major reason was fuel problems. I had a diagnostic test done on it and the BMW repair shop stated that I needed all injectors, spark plugs and a fuel inlet valve replaced which will cost about 2200. The problem I have is that BMW published this information to correct an ongoing problem with 535I twin turbo fuel system; however at the consumers' expense. I spoke with a supervisor in customer relationship and she stated that BMW was not response for or repairing it.

2009 BMW 535I. Consumer writes in regards to engine malfunction that caused vehicle fire. The consumer stated the vehicle was in the process of being towed, when it caught on fire. The consumer stated there was no unusual service history. The high pressure fuel pump was replaced twice, once as a recall. The vehicle was serviced for stalling problems, which was the same issue that occurred on the day of the fire.

My first incident occurred while I was traveling on I-185. My vehicle suddenly lost power and began sputtering and check engine light came on. This happened while traffic was heavy but miraculously I was able to merge over to the emergency lane and exit off the interstate. BMW dealership diagnosis it as a failed in-tank electric fuel pump and sensor. It was repaired and I paid $1254. Unfortunately, a week later, I experienced another loss of engine power and check engine light came on while I was traveling on the interstate. This time BMW dealership told me they had to upgrade software and change out some injectors and that should solve my problem. I bought this car to drive it and not send it back and forth to the repair shop.

Purchased a BMW 535I X drive in April 2009. Since April 2010, the car has been in for service 4 times, most recently August 2010. All 4 times, the car's engine lights have come on - oxygen sensors have been replaced twice. A problem in the fuel area/catalyst converter was just fixed in July. Last problem was at 18,400 miles - driving on highway at 70mph out of town in another state at 10:45pm, an audible signal went off and then 2 engine lights appears in my speedometer area. Also, in the navigation area, engine malfunction reduced power error message. The car began shaking and the power was reduced down to 40mph. At that point, 225 miles from home, needed to turn back and drive 45 minutes from the city that I just left. Car was towed to a city 60 miles from there and the service manager told me immediately it was the hpfp problem. At that time, he also stated that the fuel injectors are not a problem now, but it is very likely that they will go bad within 6 months from now. Confidence has been lost in this new car and safety concerns for driving this car more than 25-30 miles out of my home city. Extremely concerned about breaking down and stranded again.
