What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2022 BMW M340I, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
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.

The brakes failed at high speed. Yes the vehicle is available for inspection. The car hit a barrier and flipped on its roof. Yes, I and my passenger were both at risk of serious injury. No independent confirmation has taken place at this time. No warning lights indicated malfunction.

Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
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.

From owner reports, verbatim
Water pump failure and coolant reservoir leak.

Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
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

Steering
Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
The contact owns a 2022 BMW M340I. The contact stated that after starting the vehicle, the power steering failure message was displayed, and the steering wheel was difficult to turn in either direction. After approximately one hour, the vehicle was restarted, the failure was self-corrected, and the steering wheel operated as normal. The vehicle was taken to the local dealer on two separate occasions due to the failure, but no cause for the failure was found. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was provided. The approximate failure mileage was 300.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
