Consisent failure of coolant line system. First noticed warning light "low coolant" and immediate overheating in November of 2021. Had the issue repaired at mechanic in 11/2021. Then same exact issue recurred in April of 2023, starting with warning light of "low coolant." Received letter from BMW USA indicating the problem can be repaired at any authorized dealership, but that this was NOT a recall. Took my car to authorized BMW dealership and got the same problem repaired. Just had the same exact thing happen again, same warning light, and took back to same authorized dealership to check the repair and was told multiple issues with the coolant line and had to pay $1900 for the repair. I am being told by several mechanics that this a design defect/flaw in these models of 4-series BMWs from 2015-2019 years. I am being warned that this issue will likely recur in the next 6-8 months.

The vehicle was taken to the dealer, who determined that insufficient and poorly completed body and electrical work was the cause of the failure. The vehicle was not repaired, and the dealer declined to offer further assistance due to the poor condition of the aftermarket parts used to repair the vehicle, which the contact stated he was unaware of at the time of purchasing the vehicle. The manufacturer was not notified of the failure. The failure mileage was 57,700.

Oil filter housing and coolant leak from same housing. While driving, safety warning light came on and car began to overheat. Per several mechanics, this is a known issue with BMW Series 4 from redesign in car after 2017. Redesign implemented plastic housing which cracks and leaks. Same issue also listed as problem when researching on internet (hundreds of listings). Housing and seal cost $574 in parts but labor cost $2199.40 due to location of repair. My car had 55,000 miles on it and is housed in a garage.

I have a BMW 430i Gran Coupe, there was a system coolant leak and now they are saying the entire system needs to be replaced because the plastic cracked and eroded from wear and tear. I began checking and found that over 1 million BMW vehicles were recalled for coolant system problems. My car seems it wasn't covered under the recall. I found a service bulletin which stated that certain BMW repairs were necessary to replace coolant line. 2 Service Bulletins - SI B01 29 16 and SIB 17 01 21. I believe my car was covered under the recall that affected EGR module, the issue I am having now could also have been affected by this recall. I see many people online complaining of the coolant leak issue. I had to wait until I got paid to fix it. They are telling me it will cost about $5,000 to repair. Please help.

I was the driver and I stopped at a traffic light. I leaned over toward the passenger seat and the driver’s seat belt came loose from the fixed attachment point at the driver door side of the seat. The seat belt tensioner was recently replaced at the local BMW dealer. There was no warning or other indication that the seat belt anchor point was not secure. I am taking the vehicle back to the dealer for repair on Monday, June 20. Whether this is a manufacturing, assembly or repair issue is unknown. However, there was no advance warning and the seat belt suddenly was rendered useless, which is an unacceptable safety risk in the case of an accident, regardless of whether it is a manufacturing issue or the result of a negligent repair.

FRIEND WAS DRIVING DOWN FREEWAY. SUDDENLY HEARD A LOUD BOOM, AND THE SOUND OF ROAD NOISE. PULLED OFF FREEWAY. FOUND THAT SUNROOF HAD SPONTANEOUSLY SHATTERED. THE ONLY REASON THIS DIDN'T HURT THE DRIVER WAS THAT THE SUNROOF SHADE WAS PULLED. THE DEALERSHIP (LONG BEACH BMW) CLAIMED THAT THIS WAS A RESULT OF AN IMPACT. NO EVIDENCE OF SOMETHING HITTING IT WITH ENOUGH FORCE TO CAUSE THIS SHATTERING IS VISIBLE. IN FACT, THE PICTURE SHOWS THAT THE SUNROOF EXPLODED OUT WHEN IT SHATTERED. (LOOK AROUND THE HOLE AND YOU WILL SEE THAT THE SUNROOF GLASS WAS GOING OUT.
