“I own a 2004 Bmw 525I with 92,000 miles on the engine. I experienced my car cutting back and thought I needed a tune up. I called my mechanic who stated I didn't need a tune up. He requested that I bring the car in to the shop. The next week I was driving along and the car slowed down losing acceleration. The message on the diagnostic screen stated transmission fault . Car will lose acceleration and you may not be able to go into reverse . Failsafe status..drive moderately. I took my car to my mechanic. He put the car on the diagnostic machine and stated no code was indicated. …”
NHTSA complaint #10284870, filed 2009-09, 92,000 miles“Sudden acceleration on a Bmw 525I 2004. No previous incidents. While turning into a parking space, perpendicular to the road, in front of a bakery, during the final approach the engine suddenly accelerated, abruptly and without a reason, going over the bump stop. The car ended up in the sidewalk, no injuries (fortunately no pedestrians were on the sidewalk at the time). Luckily the driver had the foot on the break pedal and could take action preventing a crash with the building's door and avoiding hitting the people inside the shop. Car was taken to the dealer and will undergo testing. …”
