The contact owns a 2017 BMW 430I. The contact stated while driving 30 MPH, after activating the A/C unit, the contact heard an abnormal rattling sound coming from the vents, and the A/C unit failed to blow cold. There was no warning light illuminated. The vehicle was taken to the dealer to be diagnosed. 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.

THE CAR WAS RUNNING AND IN PARK WHEN THE TOP WAS INITIALLY LOWERED AND RECEIVED THE MESSAGE THE FIRST TIME.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2017 BMW 4 Series Gran Coupe verdict →
