I am submitting this complaint regarding ongoing and potentially dangerous mechanical failures involving my vehicle that have repeatedly occurred despite numerous repair attempts by the dealership. Over the past year, I have taken my vehicle to the dealership more than 10 times for serious recurring issues. The problems have included: drivetrain malfunction warnings engine warning lights oil leaks smoke coming from the vehicle the vehicle unexpectedly shifting into neutral while driving sudden loss of drivability requiring the vehicle to be towed the dealership has repeatedly stated that the issues were repaired, and at one point even provided a one-year warranty on the repair work. Despite this, the same problems have continued to occur. Most recently, the drivetrain malfunction warning and engine light returned again, smoke came from the vehicle, and the car shifted into neutral on its own, becoming completely undriveable and requiring towing. I have spent more than $10,000 on repairs related to these ongoing issues, yet the vehicle remains unreliable and unsafe. My primary concern is the safety risk posed by the drivetrain failure and the vehicle unexpectedly shifting into neutral while in operation. I am requesting that this matter be reviewed as a potential vehicle safety issue. I believe these repeated failures may present a serious risk not only to myself but potentially to other drivers as well. Thank you for your attention to this matter.
It has come to my attention that liquid from the positive crankcase ventilation (pcv) system may leak onto the water pump electrical connector. This condition can lead to an electrical short circuit and, in rare cases, may increase the risk of a vehicle fire. This issue presents a serious safety concern for vehicle owners and others on the road. A failure of this nature, especially one that carries a fire risk, warrants immediate review and corrective action. I respectfully request that NHTSA investigate this matter and determine whether a safety recall is necessary to address this defect. The dealership noticed the leak beginning at the weep hole of the waterpump. No incident occurred this is for preventive measures and review for recall and reimbursement.
We had an oil pump failure that was because the part was plastic, not metal.
Oil pump failures have been reported across multiple production years, and affected vehicle population boundaries remain unclear. Because this condition can result in sudden vehicle disablement without adequate warning especially in the cold, I believe this issue warrants investigation as a potential safety-related defect. Loss of lubrication can cause the vehicle to become disabled without warning while driving or shortly after startup. This creates a safety hazard, particularly when vehicles become immobilized in active traffic or during winter conditions the cold is when they fail the most, where occupants may be exposed to freezing temperatures while awaiting assistance.
Component failed: engine starter relay and starter motor assembly. The vehicle stalled in traffic and ignited upon a restart attempt. The vehicle is a total loss, currently held by [insurance CO] at [location/lot #], and is available for inspection. Safety risk: the driver’s life was at immediate risk. The vehicle stalled in active traffic, creating a collision hazard, followed by a rapid, uncontrollable engine fire. The driver suffered smoke inhalation and severe trauma while escaping. A delayed exit would have been fatal. Confirmed by dealer: the failure mirrors the defect pattern in recall 25v-636 (starter relay corrosion). While the fire prevents reproduction, the vehicle had a consistent service history with no prior electrical issues. Inspected the vehicle was inspected by [insurance CO] and declared a total loss. [optional: the fire dept. Responded under report #[number]]. BMW was formally notified via demand letter on [date]. Warning lamps/symptoms: no prior warnings. The failure was acute. A "drivetrain malfunction" message appeared seconds before the stall. Smoke and flames appeared immediately upon the attempted restart.
1. Whenever I refill my tank the car will start knocking. It will be only for 1 or 2 sudden jerks. I have tried every grade and nearly all the brands of fuel but its still the same. Even I escalated the same issue when I had my car service done. But to no avail. It happens when I refuel the tank. Otherwise, no issue to my surprise. I need to know if it’s a known issue? if yes then why no one reached out to me to provide solution for it? its been years I have tried to escalate it but no resolution. 2. When I use turn signals (either left or right) it start skipping click sound. Even when the engine is on and even when auto engine start is switched off. It happens not all the times but occasionally. I also escalated it when I went for service but I was told if its not logged in system then nothing cant be done. For both issues I dont see any resolution. First issue is way too annoying as sometimes I loose power to engine.
