2021 BMW 228I problems

Prior to the repair, the vehicle displayed fault codes 100227 and 100229. The dealership technician informed me that faulty wiring was identified as the cause of the problem. After the vehicle entered limp mode, I was stranded on the roadside for approximately five hours awaiting assistance. The vehicle then required towing to the dealership because it could not be safely operated. The circumstances surrounding my vehicle's failure are particularly concerning because they involve electrical wiring and connector issues similar to those addressed by BMW in the federal safety agency Recall 24V‑608. Although BMW may contend that my vehicle is not included within the recall population, the technician's diagnosis identified faulty wiring, and the symptoms I experienced—including vehicle malfunction, limp mode activation, fault codes 100227 and 100229, loss of normal vehicle operation, and the need for emergency towing—are consistent with the type of electrical system failures that BMW has already acknowledged as a safety concern in other BMW vehicles. BMW has admitted in Recall 24V‑608 that improperly sealed electrical connectors can lead to electrical faults and short-circuit conditions. The fact that BMW initially informed me that there was no physical problem with the throttle system yet subsequently replaced throttle-related components while the vehicle continued to exhibit electronic warning messages, including seat calibration errors, raises serious concerns regarding the root cause of the failure and whether a broader electrical defect remains unresolved. The technician's finding of faulty wiring further supports the conclusion that this was not an isolated component failure but part of a known pattern of electrical system issues that BMW has previously addressed through recalls and service campaigns. During the repair process, I was initially informed that nothing was physically wrong with the throttle system. However, the throttle-related component was later replaced as the proposed

THROTTLE BODY ACTUATOR BMW OEM PART # 13547619008 FITS ALL BMW MODELS 2016-2024. IT HAS BEEN REPORTED TO FAIL ACROSS MULTIPLE BMW MODEL LINES, particularly in the E60, E90, and E92 series. when it fails, the engine power goes into a safe mode which drops the rpms down to idle speed around 500 rpm and the car can only go a few mph. this happened on the freeway in lane number one at the speed limit, and it was only by a miracle I got to the shoulder without a major potentially fatal accident. BMW lied to me and told me that NHSTA is responsible for policy recalls, but you told me they initiate them on their own. Left to police themselves, they are not recognizing the widely reported failure as a recall, and the repair was thousands after almost causing a fatal accident.

I have a 2021 with 25000 miles and a 2023 with 6000 miles which make noise when in reverse. The dealer has stated the rear brake pads likely need replacement and rotors as well. It seems questionable that two exact models two years apart and 20000 miles apart are encountering the same issue.
