The vehicle was taken to the dealer, who determined that insufficient and poorly completed body and electrical work was the cause of the failure.

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.

Hi There, I recently received a recall notice for cylinder head ventilation line to be replaced in my BMW 430I 2017. Although, This part was replaced by BMW Riverside and I paid $1400 for this part BMW Riverside in March 2021. I contact BMW customer service for refund but they refused. Please assist. See attached copy of recall notice and service documents.

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.

Tire warning system came on and found that front drivers side had no air in it, since it's a run flat tire I was able to drive slowly for just a few miles to home. After filling the tire with air I found that the sidewall was leaking excessively. No visible hole but a bulge in the outer layer causing air loss. No scuffs or any other other damage to tire or specifically sidewall. Mileage is 22,700.

AFTER PUTTING THE HARDTOP DOWN AND RECEIVING THE COMPLETE MESSAGE, I THEN GOT ANOTHER MESSAGE SAYING 'RETRACTABLE TOP NOT LOCKED'- SEE OWNERS MANUAL.

I HAVE BEEN GETTING THIS SAME MESSAGE WHETHER THE TOP IS UP OR DOWN SINCE PURCHASING THE VEHICLE AND IT HAS BEEN IN THE SHOP ALMOST THE ENTIRE 3 WEEKS I HAVE OWNED IT! THE CAR WAS RUNNING AND IN PARK WHEN THE TOP WAS INITIALLY LOWERED AND RECEIVED THE MESSAGE THE FIRST TIME.
