2007 BMW X5 SAV Transmission and drivetrain Problems

“It was 9:57a.m. Saturday, november 8th 2014, started driving the vehicle, and noticed that the whole drive train would slightly jerk while driving and applying 15-25% of load, (I bought a vehicle two months ago, and from the first day - on cold - it would make the same symptom for couple of first 500-700 yards, after couple of stops and goes, vehicle heats up to operating temperature and the vehicle would drive normally.) at 10:20a.m, same saturday, I made a full stop on a stop sign turning right to a main street. …”

“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. …”

“When accelerating from a dead stop, the car does nothing when you step on the accelerator and then lunges forward. The sudden bucking and hesitation makes hard to control the car especially in bumper to bumper traffic. I live in a suburb of new york city and I drive in stop and go traffic at 5 times every week. This does not happen every time you accelerate, but mostly when the car is hot, like in traffic. The car performs fine when it is cold. The dealer has experienced the problem, and the car has improved, but it is still bad when it gets hot. …”

“Vehicle experiences dsc and awd and 4x4 malfunction while driving. When the error occurs with gas pedal depressed, car will hesitate by going into neutral and jumping back into drive accompanied by engine revving up to above 3000 RPM. When the error occurs and the gas is not depressed, car will go into neutral and coast, until I engage the transmission. If the car is traveling less than 5 MPH and the error occurs, then the car jerks to a halt and the transmission is switched into park automatically. This typically happened in stop and go traffic. …”

“On 13 july, 2011, with only 56,201 miles, our Bmw x5 suffered what an independent Bmw auto repair shop later diagnosed as a total electrical meltdown involving almost all powertrain components and data bus system. Symptoms upon startup that morning included a level control system malfunction light, a transmission malfunction warning, a parking brake malfunction warning, a passenger restraint malfunction warning, an all-wheel drive, dsc, ABS, and emergency abv malfunction warning, as well as rapid windshield wiper movement and an intermittent engine start button. …”
