2007 BMW X3 SAV: sudden unintended acceleration

Filed May 7, 2013 · Acceleration · 48,500 miles · CA · crash · 3 injuries

My 2007 x3 was involved in a bizarre and freaky solo accident. My house is on sloped hill with a level driveway. The road leading to the driveway is about 20-25 feet below the driveway. On apr. 18, 2013, upon entering the driveway, the car suddenly accelerated, hit concrete columns (on the edge of the driveway, meant for retaining walls) 3 times and went airborne from the edge of the driveway onto the street below. The car hit the street surface on its roof, rolled over once and came to a stop on its 4 tires. Driver and front passenger had seatbelts on and received minor injuries. The rear passenger was ejected from the car and suffered major injuries and still remains hospitalized 18 days after the accident. I have contacted bmw of north america and they have assured me that they will investigate this accident. After doing searches online, I am becoming more and more convinced that this is in fact a car malfunction and not a driver error. Http://forum.roadfly.com/threads/13163648-sudden-acceleration-with-08-x3-anyone-else I would like to establish contact with other bmw owners that have had similar experience.

Tl* the contact owns a 2007 bmw x3. The contact stated that while driving various speeds and attempting to engage the accelerator pedal, the vehicle would hesitate and then lunge forward abnormally. The vehicle was taken to the dealer who was unable to diagnose the failure. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure and the current mileage was 64,000.

Transmission or torque converter has some serious problems. When pressing on the gas pedal from low speeds there is barely any acceleration in 1st and 2nd gear under 2,000 rpms, but when 3rd gear goes in car accelerates more than desired most of the time. This is most apparent when car is cold, but never goes away completely. This really bothers me as this usually happens during turns when you slow down and when you want to accelerate you don't know how hard to press on the pedal, if you press too much car jumps ahead, if not enough you barely move. Another problem is that when coming to a complete stop when transmission downshifts you can hear a faint thump of every downshift somewhere under the vehicle and a little surge forward. I've been to the dealer as the car is still under warranty, they reprogrammed the computer but there was no change.

Bmw x3 sav surges forward or looses power unexpectedly. Unexpected power surge happens mostly when taking turns, coming out of the turn the car takes off. Loss of power, happens often when going up a hill or sometimes after a stop to take a turn then all of a sudden accelerates uncontrollably. Have had car in to dealer 5 times and still is not resolved.

2007 bmw x3. The six speed automatic transmission shifts poorly at slow speeds going up hills. Vehicle will lunge forward after down shifting to too low of a gear and over rev before up shifting. The gear selection seems inappropriate when going slow speeds. The vehicle has been to the dealer twice to address these problems; however, the present software fix did not rectify the problem.
