FireFiled: Aug 2024

Your car experienced multiple serious problems including a stuck trunk door, backup camera malfunction, drivetrain warning light, and spontaneous alarm activation. Most critically, your car caught fire under the hood near the driver's side windshield, which you were able to extinguish with a water hose before emergency services arrived. The vehicle was declared a total loss by your insurance company. This issue may require a complete electrical system inspection and battery/charging system diagnosis to identify the fire's root cause.

Your turbo's wastegate actuator failed, causing your engine to suddenly lose power and triggering a drivetrain malfunction warning on your dashboard. An independent mechanic confirmed the issue. BMW has reportedly extended warranty coverage to 15 years/150,000 miles for this same part on similar 2017-2020 models. Fixing this will likely require replacing the wastegate actuator assembly on your turbocharger.

highPOWER TRAIN,ELECTRICAL SYSTEM,SERVICE BRAKES
Filed: May 2024

Your vehicle experienced multiple issues starting with a battery and powertrain problem that produced loud noise from underneath, along with a rear tail light fault code. The service center forgot to reinstall clamps, and after driving over 200 miles, the fault code returned — the dealer admitted negligence. Your car then cycled in and out of service for several months (September 2023 through February 2024) with repeated electrical and brake-related codes, leaving you concerned about safety and potential manufacturer defects. Repairs may involve replacing battery terminals, reinstalling engine bay clamps, diagnosing electrical faults, and troubleshooting brake system sensors and wiring.
