Car indicating drivetrain malfunction and BMW has a service bulletin for the described issue which is to replace the transfer case yet the dealer service center has tried to say it was the radiator blinds and it was not, now saying its spark plugs and ignition coils yet there aren-??t any fault codes for it. The car has lost power while on the freeway and could be potentially dangerous since it happens while driving. Plenty of other vehicle owners reporting the same issue yet bmw not being held accountable.

Vehicle Purchase from BMW of Devon Dear BMW Customer Relations Team, I am writing to express my deep disappointment and frustration regarding my recent experience with a Certified Pre-Owned (CPO) vehicle purchased from BMW of Devon. As a loyal BMW customer, I expected a higher standard of quality and service than what I have experienced. I purchased a 2020 BMW X5 (VIN: [XXX] in October 2023 with the confidence that it had undergone a rigorous inspection process, as advertised under your CPO program. However, after driving the vehicle for only 5,000 miles within a single year of ownership, I have been informed that the following costly repairs are required: 1. Brake pads replacement 2. RPLC both LW ctrl ar 3. Rear brake rotars 4. Front thrust arms 5. 4wa integral alignment The estimated total cost for these repairs exceeds $5,000, which is entirely unacceptable given the short duration and low mileage since the purchase. This indicates either a lack of proper inspection and servicing by BMW of Devon or a failure to disclose critical information about the vehicle-??s condition at the time of sale. As a consumer, I relied on the assurances provided by the BMW CPO program, which is marketed as delivering -??ultimate peace of mind-?? and a vehicle of premium quality. This experience has instead been stressful and costly, undermining my trust in the BMW brand. I demand that BMW of Devon and BMW of North America take full responsibility for these shortcomings by covering the cost of all necessary repairs immediately and free of charge. Anything less would not only fail to rectify this issue but also tarnish BMW-??s reputation for quality and customer satisfaction. I hope this matter can be resolved promptly and amicably. Please respond within 10 days to confirm your commitment to addressing this issue. Should I not receive a satisfactory resolution, I will have no choice but to escalate this matter further, including but not limited to contact INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATI

How does a known manufacturing defect ( or the factory-filled transfer case oil does not meet BMW specifications.) Not become a safety concern. The wheels have intermittent power from the transfer case. My car showed the concern at 55k miles and the warranty company made me go through another 12 months of the shuddering issue before replacing. When moving from winter to all season tire it became more noticeable. When setting off from a slope my power loss was even greater causing the front wheels to slip from the shuddering power train. This possess a greater risk on loose paving.

While parking the vehicle in a head-on parking spot, the car suddenly accelerated without warning and hit a wall. The car then went into reverse and sped up rapidly until it hit a concrete patio on the other side of the parking lot. The brake pedal was depressed with substantial force the entire time the vehicle was moving but the vehicle would not stop moving. The brakes did not engage. I do not recall how the car went from drive to reverse. Fortunately, there were no people or cars in the parking lot at the time of the incident. The auto body shop that currently has possession of the vehicle could not find anything wrong with the computer/electrical systems in the vehicle nor were they able to recreate the incident. I do not know how thorough they looked for problems. BMW has been notified and hopefully they will send a crew to investigate. The car is currently at the auto body shop but my insurance gompany, geico, will have the car towed to one of their facilities in a couple of days. The car has been deemed a total loss due to all of the damage. I have been having electronics issues with the car since purchase in June 2020, however, they have been related to the entertainment and communication systems. In hindsight, I realize that I had two other instances in the past with sudden acceleration with this car. I thought nothing of it at the time but they may be related to this latest incident.
