2018 BMW 320I Problems and Recalls (21 Complaints)

After tightening the harness, the straps slip and loosen completely on their own without pressing the release button. This happens due to normal movement while driving, leaving my child completely unrestrained and unprotected. I have already followed the manufacturer guidelines to thoroughly clean the adjuster mechanism and the strap area with warm water to rule out any debris or buildup. While it seems to hold for a brief period, the mechanical failure returns after a couple of days.

The contact owns a 2018 BMW 320I. The contact stated that while the vehicle was parked, the vehicle unexpectedly started rolling forward. The brake pedal was depressed; however, the brakes failed to immediately respond. The contact stated that the vehicle eventually came to a stop. The contact referenced an unknown recall for the failure, but the VIN was not under recall. The vehicle was driven to an independent mechanic but was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 72,000.

On 09/16/25, I was exiting the Florida turnpike onto Sawgrass Highway via the exit ramp on exit 71. As I decelerated from 60 MPH to 35 MPH to match the speed of the exit ramp, I was in the left most lane in the two-lane exit ramp. My car spun out and I lost control of the vehicle, which caused the vehicle to spin through the two lanes of the ramp several times and ended up drifting onto the edge of the retention pond on the left of the exit ramp. I probably had spun around over three times and my car hung off the edge of the retention pond with the only thing preventing my car from falling into the pond being the rocks to prevent erosion on the side of the pond. The airbags on the drivers side and the curtain airbags both had deployed upon the car coming to a stop. The seatbelts were also locked upon trying to exit the car. The car was fully serviced prior to the incident and in good standing with BMW. The brakes were recently replaced a month ago and regular milestone inspections were conducted on the car. The road conditions on the day in question were great with no water or puddles on the road.

The contact owns a 2018 BMW 320I. The contact stated that while driving 55 MPH, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The message Engine coolant system, coolant pump outside of speed tolerance" and code 20A701 was displayed. The contact stated that the vehicle failed to accelerate, and the contact drove 8 MPH back to the residence. A fuel-burning odor was on the interior and exterior of the vehicle. The vehicle was not taken to the dealer or an independent mechanic. The contact stated that on a separate occasion, while her husband was driving, the failure reoccurred. The contact's husband arrived at the residence and became aware that the water pump had failed and was no longer functioning as intended. Upon further investigation, the contact related the failure to NHTSA Campaign Number: 21V907000 (FUEL SYSTEM, DIESEL). However, the VIN was not included. The vehicle was not repaired and was parked at the residence. The manufacturer was made aware of the failure and referred the contact to the NHSTA Hotline for assistance. The failure mileage was approximately 84,000.
