general problems of the 2012 BMW X3

I emailed BMW of arlington on 5. 13. 2024 detailing the critical safety issue I experienced with my BMW X3 2012 on Sunday, 5. 12. 2024. I was driving on the tollway northbound from i20 in grand prairie in the pouring rain with my wipers on, and the car suddenly started braking and decelerating from the 70 mph cruising speed to 40 mph in seconds. The car behind me nearly hit my vehicle, and since it kept doing that, I had to turn on my hazard lights till I exited. The car was doing that irrespective of whether it was on cruise control or my driving speed. I discovered by googling it that this is a known defect in Bmws since their shop foremen and certified technicians who know more than me think I am dreaming this up—https://w w. Bimmerfest.

Driving this car on the highways in dallas regularly is extremely dangerous as I could end up in a major multivehicle mva pileup. Also, the previous time I had this issue before I brought it in on may 7, it wasn't raining, and it started with the car not even moving when I put it in reverse and pressed the gas. Then it suddenly started decelerating on the road, backfired, and shook violently at normal speeds. The car overheated as the radiator coolant leaked, and I had to replenish it. Carshield, the auto warranty company, and I paid approximately $7,000 to BMW Mini of arlington between June 2023 and today (see attached invoices_receitps_diagnosis reports). The last two times (10. 21. 2023 and 5. 7. 2024), their multi-point diagnosis on my vehicle identified no issues that need attention. Two of their service advisors who worked on my car in June and October 2023 quit immediately after completing it. The dealership does not respond to the bbb or my calls, emails, faxes, etc. BMW USA advised me to contact NHTSA. On June 1, while driving on city streets, the brakes were squealing even without engaging, and the car overheated/ backfired again/ almost caught fire.

The contact owns a 2012 BMW X3. The contact stated while driving at an undisclosed speed, the vehicle was shaking and hesitating during acceleration. An unknown warning light was illuminated. The vehicle was taken to an independent mechanic who related the failure to NHTSA campaign number: 14v176000 (engine and engine cooling) however, the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA. The failure mileage was approximately 89,000.

The contact owns a 2012 BMW X3. The contact stated while driving 40 mph, the vehicle was driving rough before stalling with the drivetrain malfunction warning light illuminated. The vehicle was taken to the dealer where the vehicle was diagnosed with a fault code variable camshaft timing control. The dealer made other repairs to the vehicle, and the fault codes disappeared. However, the contact stated that the failure persisted. The contact took the vehicle back to the dealer and a local mechanic who confirmed a failure with the vanos system. The contact referenced NHTSA campaign number: 23v707000 (engine and engine cooling) as a possible solution however, the VIN was not included in the recall. The manufacturer was not notified of the failure. The failure mileage was approximately 92,669.

Spontaneous engine fire while parked on a city street. Coolant pump replaced the morning of Nov 8th 2017. One hour after picking up the vehicle from the dealer and a few short trips, vehicle was parked, shut off and locked. It drove normally and there were no warning lights. 15-20 min later engine was on fire.

We stopped for a light and the car started to accelerate while your foot is on the brake. The rpm gauge went up to around 3500 and the car was extremely hard to keep from going forward. This happened several times, the car was brought in for diagnostics but they could not find anything wrong. It happened recently and we are taking the car in again to try to resolve the problem.
