I've been experiencing drive train problems with my vehicle and upon research I've concluded that not just only me but many people with the same vehicle as mine have been having transfer case/driveshaft/differential problems and the scary part is that no codes pop up for this issue!! I've already took it to many shops I've even took it to an official BMW dealership and they don't seem to help but the real reason I'm reaching out is because I nearly had a near death experience related to this issue on the freeway.. the vehicle seemed to shake violently and felt like it wanted to seize up while driving and had to do an emergency pull over but once again it doesn't throw no codes and not only that I've already spent thousand of dollars into this car for it to react like that while driving! Please hear me out and help me resolve this as soon as possible.. thank you [redacted]

this vehicle is dangerous and I cannot drive it without it smoking and overheating, exhaust or fumes get inside the vehicle not safe for my family, I bought it last year and have had problems since and I cant get it fixed. I tried to call the BMW office last year to no avail and no returned calls, I constantly had to fill coolant when driving and afraid to drive no more because smoke from engine and smell of smoke is frightening while on the road. can't drive this vehicle anymore
My 2008 bmw x5 4.8i almost caught fire. The fuel pump connector is burnt into the fuel pump harness. My local mechanic said this was like a ticking time bomb. The issue is these trucks are known for this problem and there was a recall for this but my vin coming up with no recalls when this truck is clearly apart of the bad batch , I have pictures for proof.
I noted that the vehicle was not running properly so I took the SUV into an authorized BMW service center to be inspected and repaired. I was notified that the vehicle had experienced a burned up wiring harness from a short circuit to the disa valve on the engine. I was also notified that cylinders 1, 3 and 5 had failed ignition coils, which was the reason for the poor operating performance. I was also informed that the vanos valves were sticking and May need replacing. Prior to the poor running performance, last year we experienced the car filling with smoke and had to evacuate the children and adults from the car when driving the car. The car was inspected and no problems were discovered and the smoke did not return, no codes were found. …
My 2008 BMW X5 was taken to a shop to be diagnosed due to Diagnosis as followed:( low coolant light coming on) "coolant crossover pipe from timing belt cover leaking" it is available for inspection, although it is not safe to drive. The low coolant light went off after I put more in it and did not come back on. Me and my then 10 month old were picking my 14 year old up from school and I noticed smoke pouring out of the hood. There was no warning lights or anything. Then the air conditioner started to blow smoke out as well. I cut the car off and it continued to smoke for approximately an hour. The car was about to catch on fire with no warning lights and the hazardous smoke out of the vents. The problem was diagnosed by Dan's Auto Center. I can not move my car because it will smoke at the engine and cause a fire risk. The low coolant sensor came on a few days after purchased. …
