I am submitting this complaint regarding a 2015 BMW 435xi (N55 engine, ~79,000 miles) that suffered a sudden and complete engine failure due to the oil pump drive chain. While driving at highway speed, the vehicle experienced an instant loss of oil pressure and engine seizure without any warning lights or prior symptoms. I barely managed to steer the car to the shoulder and avoid being struck by surrounding traffic. This was a serious safety hazard, as the loss of power and steering control occurred in active highway conditions. Inspection revealed a catastrophic internal failure of the oil…
A warning message comes on saying the front passenger air bag sensor is defective. I checked with the BMW dealership and with the used car company I bought the car and "bumper to bumper" warranty. The used car company confirmed the car has a bad sensor but I have to pay $1,100. BMW has had several recalls involving sensors in other models and even problems with the 2015 428i convertible. My car had less than 50,000 miles when the fault 1st popped up July 2024. I believe this should be recallled.
Water accumulation in the rear passenger side when it rains. Can hear slushing water when driving. It accumulated all the way to the luggage compartment and caused the Control unit rear electrical and the ASD module to fail causing $2564.61 in repairs. Was wondering if this is the case of the issue [XXX] . When I read online there Is a lot of complaints about this. Has BMW ever acknowledged the issue? [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
I own a 2015 BMW 435i from Checkered Flag (Jaguar) in about 2017. The car is currently experiencing a fuel pump failure of exactly the type that is described here: [XXX] . Your VIN lookup does not show my car is covered by the recall, even though my car is exactly the make and model described in the recall notice. Moreover, the defect my car is experiencing is exactly the defect described in the recall notice. It makes little sense that some cars of this make and model would have a fuel pump problem but not others; it is far more likely the fuel pumps are common to all cares of this make and…
There is a ebrake bracket made of plastic underneath the car but that sits above the drive train running from the front to the back parallel to the drivetrain. It's not protected by a heat shield and is only made of thin plastic. My has been replaced three times already and is already needing to be fixed again on a car with only 76k miles. The high temperatures from the exhaust melt the plastic and cause the cable to fall on to the drivetrain. It's only the matter of time before it gets caught in the drivetrain or wraps around causes an accident and serious bodily injury. I am shocked to see…
I car hit me from behind and pushed me into the car in front of me and my steering wheel came off and my air bag on steering wheel did not deploy. As a result the wheel pushed in my chest.
