Unintended acceleration with loss of braking effectiveness. We hit a tree head on going at least 50 by the time we struck it. The vehicle was inspected before we bought it and we only bought it 3 days before the accident occurred. The check engine light came on that afternoon and we were going to get it checked out on Monday.

On multiple occasions while driving the car, first the ABS light would come on, then most other warning lights, then the car would lose all power, engine would stop, can't shift transmission, basically did on the road. Had battery replaced and registered. Happened multiple times again. Seems to be a common problem https://www.bimmerfest.com/forums/showthread.php"T=888938 one link in there sent me to https://www.ebay.com/itm/BMW-135I-335I-435I-535I-X4-X5-X6-engine-wiring-harness-12517592511-7592511-oem/123598545546"hash=item1cc70C228A:G:pueaaoswpyxcp-mk all happened when car was in motion driving, typically on a highway in traffic.

The transmission mechatronic sealing sleeve leaked fluid and left puddle of oil/fluid on my garage floor. The early diagnosis showed engine oil leak and eventually concluded it was transmission fluid leak recently, while the vehicle leaked the fluid during a long period of time that we don't know how much it leaked already. The transmission is a sealed unit and owner has no way to check the fluid level via a dipstick or any mean. The automatic sensor system only checks engine oil, brake fluid, power steering fluid, etc but not reports transmission fluid level. So, there is no way any BMW owner would know if the transmission fluid is low or totally empty. This would post safety issue if a vehicle breaks down in a middle of traffic due to transmission fluid leak problem without any warning sign. Furthermore, BMW has published a technical service information "si B 24 08 06" dated March 2010 for this particular problem. BMW did not notify owner to check the vehicle for sign of transmission fluid leak, nor asked dealer to inspect the vehicle during service visits. As a matter of fact, my 2007 X5 has never been inspected for this problem but it clearly had this problem! considering it is a low mileage vehicle, this problem should not exist normally. Thus, the workmanship or material BMW used in the (transmission) assembly factory has poor quality and causes this safety concern. There was a saying if a vehicle was driven too much, or a vehicle was sitting there or not been driven for a period of time, it would have this problem. Such a saying should not be a factor of design or quality control of BMW (or any) vehicle and I urge BMW recalls all vehicle to check for transmission leak due to this problem and pays for all necessary repair.

The contact owns a 2007 BMW X5 MINIcooper. The contact was driving approximately 25 mph on normal road conditions with the cruise control activated. There was an unintended increase in acceleration. The vehicle failed to slow down when pressure was applied to the brake pedal. The gear was shifted into the "neutral" position. The vehicle crashed into a traffic signal pole. The air bag system failed to deploy with the level of impact. The driver sustained severe injuries. The police was called to the scene. There were body damages to the front passenger side of the vehicle. The vehicle was towed to a collision center. The cause of failure has not been determined at this time. The failure mileage was 22,000. The VIN was unavailable.
