Power train, Engine, Aug 21, 2026
The left hydraulic engine motor mount (P/N 22117581621) completely collapsed and failed at 6 years and only 24,811 miles. The right mount was also replaced at the same time (P/N 22117581622). The failure allows unsafe, excessive engine movement and shifting under rotational torque loads. This shifting creates an immediate safety hazard, risking the sudden compromise of surrounding mechanical systems, cooling lines, and electrical harnesses while the vehicle is in motion. BMW North America acknowledged the premature nature of the failure by approving a goodwill repair for the labor costs but forced me to pay out-of-pocket for the defective parts. The engine mount issue was detected when the vehicle went in for normal services and the known recall for the engine starter which had the potential to cause bodily harm as well as property harm due to fire risk, even when the engine was off.

The contact owns a 2020 BMW 330i. The contact stated that upon starting the vehicle, the starter made an abnormal, grinding metal-like sound. The vehicle was taken to the dealer, who diagnosed that the starter had failed. The starter was replaced under NHTSA Campaign Number: 26V056000 (Electrical System); however, the vehicle failed to start one morning post-repair. The message "Engine Cannot Start" was displayed. The vehicle was towed back to the dealer, where it was diagnosed that the starter failure had caused damage to the battery. The dealer informed the contact that the battery needed to be replaced prior to the starter replacement. Additionally, the contact was informed that the transmission harness, signal wire, and ending harness had overheated and needed to be replaced. The manufacturer was made aware of the failures, and a case was opened. The failure mileage was approximately 110,897.

It was discovered during a routine check that the alternator for my 2020 BMW 330i with xdrive was dying. The car had around 40,000 miles on it. Alternator was replaced with an aftermarket part.

Good afternoon. I have called and spoken to my local BMW dealership at Grayson BMW service department many times. As of today they report no remedy and have no idea when a resolution will be available. Filing this complaint (second formal written complaint) due to lack of this not being in any sort of "timely manner." This recall is noted as an URGENT FIRE RISK WHEN PARKED for almost seven months now. I have parked the car outside and through the winter and now getting into the summer. In looking up this recall and reading associated documents, it seems there has been a remedy to many makes and models but still nothing for the 2020 330i, and no word on what to do, advisement, or timeline on resolution. I called the NHTSA hotline but after waiting, decided to attempt another written complaint. Previous complaint #11712900. Thank you, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2020 BMW 330I. The contact received notification of NHTSA Campaign Number: 25V636000 (Electrical System); however, the part to do the recall repair was not yet available. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the issue. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had not experienced a failure.
Engine, Apr 6, 2026, fire
My car was parked at home and hadnt been driven in hours. My neighbor contacted me, saying that my car was on fire. I went outside, and it was on fire, and the fire department was called. After BMW conducted an investigation, they deemed the car fire to be related to the active recall. The manufacturer (BMW) is violating the National Traffic and Motor Vehicle Safety Act (49 U.S Code Section 30120) by refusing a "remedy without charge" for recall 24V-536. A manufacturer is required to provide a remedy for a safety recall "without charge." BMW is offering a loan payoff (21,851.37). This current offer violated this federal statute by forcing me to absorb the loss of my 2500 down payment and accumulated equity. Additionally, Case Management is threatening to revoke my essential transportation (loaner) unless I sign a settlement that omits a verbally promised 4,000 credit buy with non-complaint conditions: it is a restricted discount only valid for future BMW purchases, it was omitted from the legal contract that I am being pressured to sign, and it places burden on me, the victim, to find a replacement vehivle while threaten to revoke my loaner transportation. This is a clear attempt to bypass the federal requirement for a free and complete remedy for a dangerous safety defect. I have attached a picture of the fires along with the fire department report, and the email thread between Case Management of BMW and me. On March 25, 2026, I was offered a loyalty goodwill of 4,000 after the purchase of a BMW from their dealership. March 26, 2026, I was told to contact my loan finance company to inquire about a collateral substitution. After I emailed the CEO and VP of BMW executives, I was then asked about what car I was interested in as a substitute for collateral. March 31, 2026, I am told to coordinate with the dealership as well because the BMW corporation doesn't coordinate with the dealership about the substitution of collateral.

The Active Grille Shutter (AGS) system on my vehicle suffered an internal mechanical failure (fault codes 138206 and 138224). These shutters are a critical part of the engine cooling system. Failure of the AGS to operate correctly leads to immediate engine overheating risks, potential sudden loss of power (Limp Mode) in high-speed traffic, and thermal damage to engine components, posing a severe safety hazard. The manufacturer, BMW of North America, has officially acknowledged this defect via Extended Warranty SIB 01 03 25. However, both the local dealer (BMW of Sterling) and BMW of North America corporate office have formally refused to honor this safety-related warranty repair. Despite clear video and photographic evidence showing zero external impact to the vehicle's front end or grilles, both parties claim 'outside influence' without providing any technical proof or documentation of such impact. By refusing to repair a known cooling system defect, the manufacturer and the dealer are forcing a vehicle with a high risk of overheating back onto public roads. This represents a systemic failure to address a safety-critical component under a federally protected warranty
Air bags, Feb 5, 2026, crash
The contact owned a 2020 BMW 330i. The contact stated that while accelerating from a complete stop and making a left turn, another vehicle, trying to beat the light and driving 60 MPH, crashed into the driver's side of the vehicle. The contact was trapped because the front driver's side door failed to open. The air bags failed to deploy. The police officers delayed their arrival, and a police report was not filed. The contact was in shock. The contact drove to the residence and was able to exit the vehicle through the front passenger's side door. The contact sustained C8-T1 nerve injuries, spinal injuries, and underwent surgery, developed myelopathy, severe PTSD, severe whiplash, and the contact sustained right eye bruises after hitting her eye against the steering wheel. The T1 neck screw that was previously installed in the contact's neck had backed out due to the impact and was replaced. The contact was informed that she nearly sustained paralysis due to the crash impact. The vehicle was taken to an autobody repair shop, and the vehicle was totaled by the insurance company. The dealer was not contacted. The manufacturer was notified of the failure and sent an engineer who performed the vehicle inspection. The manufacturer later sent a letter to the contact, providing an engineering explanation for the air bag's failure to deploy. The failure mileage was approximately 6,500.
Steering, Engine, Feb 4, 2026
I am not sure this the the right form for filing my complaint. I was issued a recall letter in November about my car catching on fire. I have seen videos of other BMWs catching on fire. I am not sure if legally I can take it to a mechanic? What if something happens while it is at the mechanic? Legally do I have to take it to the dealership? What if it catches on fire and my neighbors property gets damaged? I have called and email BMW but no response. I need to take my BMW in for other issues but live out in the country, what are we suppose to do? It has been several months. They shouldn’t be allowed to do this. They should replace the vehicle or buy it back. It is dangerous.

I own a 2020 BMW 330i xDrive with an open safety recall involving a fire risk related to the engine starter. The recall has been open for approximately five months, and BMW has not provided a remedy or repair timeline. I have been informed that parts are unavailable, and no interim fix has been offered. This defect presents a serious fire hazard, and I do not feel safe operating the vehicle. I am currently pregnant, which increases my concern for personal safety and the safety of my unborn child. Despite the unresolved safety recall, I am still required to make monthly payments on the vehicle. BMW has not provided alternative transportation or sufficient guidance on how to safely manage this situation.

Car manufacturer (BMW) has had a recall (ID 25V636000) for over two months. It requires parking the vehicle outside away from overhanging trees, because of risk of fire. BMW knows what the fix is (replace the starter motor) but has not begun recalling vehicles. Please compel BMW to perform the repair/replacement.
Lane departure, Jan 28, 2026
On November 15th 2025, while driving at highway speed in my lane, the vehicle’s lane assist system applied a sudden and unexpected steering input. I did not command a lane change or steering correction. The steering input caused the vehicle to become unstable, rotate, and spin across the roadway, resulting in a collision with the highway barrier. Prior to the incident, the vehicle had repeatedly failed to install a BMW-issued lane assist software update despite multiple attempts following BMW’s published instructions. BMW dealership personnel were aware of the update failure. The lane assist system remained active and provided no warnings or limitations. Weather conditions changed rapidly due to a brief, unexpected ice storm lasting approximately ten minutes. The vehicle did not provide a warning, restriction, or automatic disengagement of the lane assist system under these conditions. The loss of control occurred immediately following an unexpected steering intervention by lane assist. The loss of control occurred immediately following the steering intervention.

Urgent fire risk when parked recall as of September 23, 2025 and received this safeyy recall letter in November 2025 along with 'remedy is unavailable.' Called local BMW dealership today and no remedy and no clue as to when will be available. Urgent fire risk safety recall that is 4 months without a remedy?! Is this acceptable? And no communication or updates available is very frustrating for a vehicle that is used daily for family, children, and work purposes. Please advise.

Re: 25V-636 We received a recall notice for the above notice over a month ago. No further communication has been sent from BMW in the status of new part availability and they refuse to assist with accommodations because of the scale of the recall. The letter clearly states that there is a fire risk and to not park near structures. This leaves almost everybody who owns affected cars with no option but to put themselves or someone else at risk of this car catching on fire - where else can you park a car that might catch on fire? Its been 4 months since this recall has been issued nationally and no communicated resolution or targetted timing for resolution. Im concerned this recall will potentially start a gigantic car fire and harm someone, their homes, or their neighbors' property. I find it completely unacceptable that there's not even clear resolution timing for this problem which is essentially a ticking time bomb. People with these cars need help beyond what we're able to do as individuals. Thanks, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Structure, Visibility/wiper, Forward collision avoidance, Dec 19, 2025
Within days of purchasing the vehicle, multiple warning lights and safety-related alerts appeared, including repeated check engine warnings, an alert stating “Driver Assistance Support Reduced,” and a wrench indicator referencing an auto lighting and wiping system malfunction. While driving, the vehicle felt unstable and would sway side to side, making it difficult to maintain confident control. The vehicle was brought in for service shortly after purchase due to these concerns and was removed from my possession because of the seriousness of the issues. During the service process, I was informed that the vehicle had previously been involved in an accident and that a critical structural safety component (the front crash bar) was damaged. This damage had not been disclosed prior to purchase. The crash bar is a key part of the vehicle’s body structure designed to absorb impact and protect occupants in a collision. Driving a vehicle with damage to this component posed a potential safety risk. The combination of structural damage, reduced driver assistance alerts, visibility system warnings, and unstable handling raised concerns about crash protection, vehicle control, and overall safety. The issues were identified by the selling dealer during inspection after the vehicle was returned for service and are available for further inspection if requested.

I own [XXX] BMW vehicle affected by a safety recall for a defective engine starter relay that may corrode, overheat, and cause a fire. The recall notice dated November 2025 states the vehicle is not safe to drive, with no remedy available, rendering it unusable and hazardous. Recall N0.25V-636. Under Kansas Lemon Law (K.S.A. 50-645 et seq.), I am entitled to a refund or replacement for this substantial defect impairing use, value, and safety, which BMW cannot repair. I demanded a full buyback at original purchase price, including fees, taxes, and incidental costs, or a comparable replacement. I requested a response within 10 business days. I sent this demand in November 2025 and have heard nothing since. The statute of limitations for lemon law claims in Kansas is four years from defect discovery, per UCC provisions for warranty breaches. If unresolved, I want to pursue legal action for breach of warranty, lemon law violations, and negligence, seeking damages, fees, and costs. Please investigate BMW's handling of this recall and failure to respond. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
