Electrical System
The starter in my 2022 BMW M340I sedan was faulty after 54,000 miles. It began to take two attempts to start the vehicle each time and was at risk of not starting. The first attempt all electrical components would turn on but the ignition was unable to start the engine. Then the second attempt was generally successful. I took it…

The starter in my 2022 BMW M340I sedan was faulty after 54,000 miles. It began to take two attempts to start the vehicle each time and was at risk of not starting. The first attempt all electrical components would turn on but the ignition was unable to start the engine. Then the second attempt was generally successful. I took it to the dealer and had to replace my starter to return the vehicle to normal operation. BMW has recalled tens of thousands of other starters including my model but not yet for the 2022 BMW M340i I was told.

Air Bags

The vehicle displayed a “Passenger Restraint System Malfunction” warning. Upon diagnosis by an authorized BMW dealership (Fields BMW, [XXX] ), the issue was identified as a faulty passenger knee airbag wiring harness (short to ground). The dealer confirmed that this condition is documented in a BMW Technical Service Bulletin [XXX] ), indicating that BMW is aware of a recurring defect involving this component. This failure directly affects the Supplemental Restraint System (SRS), which is a critical safety system designed to protect occupants in the event of a crash. A malfunction in this system raises serious concerns about whether the airbag will deploy properly. Despite this being a known issue, BMW has not issued a recall and is requiring customers to pay for repairs once the vehicle is outside the warranty period. I was offered only partial “goodwill” assistance (20%), leaving me responsible for the majority of the repair cost. This appears to be a systemic defect in a federally regulated safety system, not normal wear and tear. I am requesting that NHTSA investigate this issue for potential recall, as it may affect multiple vehicles and poses a safety risk if the airbag system does not function as intended.

On the day of purchase, while traveling at approximately 70mph on the Florida Turnpike, a large section of the lower dashboard assembly detached and fell onto my feet, obstructing access to the pedals., the vehicle displayed a "Powertrain Failure" warning light. Subsequent inspection of the tires revealed extreme pressure variances (ranging from 33 to 41 PSI) and multiple "sticky" or stuck tire valves, one of which remained open and caused rapid deflation. These defects represent a significant failure of the seller's advertised "150-point inspection" and posed an immediate life-safety risk at highway speeds. 01/05/2026 at 12:30pm ish
