Pedestrian alert sounds
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

In November 2025 my breaks quit working. I had AAA haul my car to a repair shop. They ran the codes on the car and found that it was related to a recall on 2021 BMW 540i's for the oil vacuum pump assembly, pan and gasket. I then had it towed to BMW and found out that my vin was not in the recall. BMW quoted me $4587 to repair this on a car with 45,000 miles. I then had it towed to a repair shop that replaced the oil vacuum pump assembly, oil pan, gasket and bolts for about $3700. I think that my vin should have been included in the recall. It was a obviously a common problem with my model and I should not have to pay this much on a car with 45,000 miles. I also had to pay $283.81 for BMW to diagnose it.

We notice the lose of braking power right after we started the car on 4/30 morning. The car was totally fine before that. took it to the BMW dealer they said the problem is "Vacuum/oil pump failing internally. fault for brake booster pressure switch, no brake boost" I find that there is a recall for the exact problem but it doesn't include my vehicle The "Part 573 Safety Recall Report 21V-598" stated that when It does happen it will cause damage to the oil/vacuum pump. I think recall 21V-598 should include my vehicle

Intermittent vibration at highway speeds. Brought to the BMW dealership and they stated the right front wheel was out of round. I never hit a pothole or anything that would cause damage. The dealer "repaired" the wheel, but the problem still exists. Brought the vehicle back and am now told that BMW has started offering non-run flat tires on new cars. I feel that the run flat tires coupled with the low-profile wheels could be the issue. Also, feel that the wheels are poorly made and are prone to being warped.

ELECTRICAL SYSTEM
The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle âÂÂdischarged batteryâ complaints.
STEERING
At low outside temperatures (below 40 degrees F) and slow driving speeds (i.e. when parking, maneuvering)with a large steering angle, the front end can be slightly axially misaligned. This can be felt (jerking)/ heard via an acoustic acknowledgement (clunk) as seen at the 11 second mark of the video. See attached video V36 01 21.
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
