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. Com/threads/sudden-momentary-deceleration-braking-at-highway-speeds. 1447635/-. 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.
As I drive and stop, my brakes stick, when I try to accelerate it struggles to go. On the highway it began slowing me down. I was scared it was going to get me rear ended because my brake lights do not come on when this happens. I brought it to my garage and they diagnosed it to be the dsc pump. They put in a used pump and fixed the issue. Please take this seriously, it is a dangerous problem.
When starting the car, the brake pedal does not depress a short distance before resistance as it did previously. Now, I have to push very hard to get it to depress any distance so that I can start the car. This usually does not occur when the ambient temperature is below 50 degrees or the car has been operated very recently.
Our X3 new X3 has surged violently ahead on two occasions now, on one occasion with foot on brake. BMW are denying any other examples of this problem exist, which by viewing this website clearly is not the case. I encourage all that have had this problem to lodge an official complaint to cause a full recall of this dangerous design flaw. Please note that we are in australia, and that BMW in germany are denying any knowledge of this problem.
