Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

The recall 25V-636 remains unresolved after more than 6 month passed since the manufacturer issued the campaign regarding the engine starter. I would like to see the NHTSA to put the manufacturer on notice that this is unacceptable. We cannot park the vehicle outside of structures permanently as this devalues the vehicle and creates a loss of use.

NHTSA ID 11595658 · filed Jun 21, 2024

RCTA system does not work (other than on rare, unpredictable occasions, and generally only when the alert is worthless) - when another vehicle or pedestrian is too close to the car to make any difference. I have had cars with RCTA for years and none of them failed to detect objects/vehicles/people at much greater distances from my vehicle that could reasonably be expected to collide with my vehicle if I continued to back up. All these other cars provided an adequate advance warning of an impending danger (another car, bike, pedestrian, etc. approaching my vehicle with which I might collide, etc.) allowing the driver to react and avoid the problem. THIS PROBLEM OCCURRED REPEATEDLY STARTING IMMEDIATELY AFTER I TOOK POSSESSION OF THE CAR IN MARCH 2021. After repeated attempts to get BMW to fix the problem, I gave up. I will note the first serious occurrence of the issue below, but it has been repeated every time I use the car and pull out of a parking space in reverse. Probably 150 times? I can compensate for this failure somewhat, but it is vastly inferior to having a properly working RCTA. I have visited BMW dealerships on multiple occasions and each time asked that this issue be addressed. The car is reviewed, and I am told the system is working as designed. My response is that the car is therefore designed to be unsafe? However, on my latest visit for regular service (24 months since start of lease) I went to a different dealership, the service advisor told me that the problem was widespread in BMW 5 series sedans and SUVs. He indicated that there is no fix available at this time. It's been two years since I brought this to BMW's attention. Service Invoice that I am attaching is from March 3, 2022 - one of the trips to the dealership to get regular service where I asked again that this issue get addressed. See Item # 4 on pages 1 and 2.

I have a code Passanger restraint failure that will not come off unless I pay $2700 to fix. This coding came on after 3 months of getting the vehicle and I’m not the only with the same issue. This is a dangerous situation that Bmw is not recalling but putting this as the owners expense. If I were to get in an accident this will not deploy airbags or open the seat belt this can cause sever injuries or worst death.

Driver’s sport seat bottom has 19 degrees of rear tilt in the lowest setting. I am unable to flatten seat bottom causing Sciatica nerve pain which causes my legs to fall asleep while driving. I have owned several BMWs with sport seats and this is the first one that has caused problems. Base sport seat needs more adjust to lower degree of rear facing tilt.

After pulling into a parking space and stopping, the braking system became unresponsive. While stopped with the foot on the brakes, attempts to place the car in park failed. After pumping the brakes, the car rolled forward as the car idled and the brakes were unresponsive as it rolled through a corrugated metal wall and the car only stopped after pressing the ignition button to turn off the car, putting anyone in or near the car at that time at risk. The problem has been reported to the dealer and the dealer inspection is pending but the problem has not been isolated and not reproduced. No prior warning lights or symptoms of a problem was noticed in this car before this incident.
