2012 BMW X3 Engine Problems

I emailed BMW of Arlington on [XXX] detailing the critical safety issue I experienced with my BMW X3 2012 on Sunday [XXX]. I was driving on the tollway northbound from [XXX] 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 [XXX] -. Driving this car on the highways in Dallas regularly is extremely dangerous as I...

ENGINE FAILURE AT 70155 MILES. CONNECTING ROD BEARING IS SPUN.

SITUATION WHEN STARTING A COLD ENGINE, A 'PLUME OF BLUE SMOKE' CAN BE SEEN EMITTING FROM THE EXHAUST TAILPIPE FOR APPROXIMATELY 10-20 SECONDS. THERE IS NO ENGINE MALFUNCTION LIGHT ILLUMINATED (NO' TURBOCHARGER BOOST FAULTS ARE STORED) AND NO DRIVABILITY ISSUES ARE DETECTED. CAUSE WHEN THE VEHICLE IS PARKED OVERNIGHT THE ENGINE OIL PRESSURE WILL EQUALIZE, THIS MAY CAUSE ENGINE OIL TO LEAK PAST THE TURBOCHARGER 'EXHAUST SIDE' TURBINE SEAL DUE TO CARBONIZATION OF THE TURBOCHARGER SEALING RING. THIS IS THE SAME ISSUE IMPACTING BMW N20 ENGINES THAT BMW HAS ISSUED A TECHNICAL SERVICE BULLETIN AND EXTENDED WARRANTY 10 YEARS/ 100,000 MILES. THE N55 ENGINE (6 CYLINDER, TURBO) HAS NOT BEEN INCLUDED IN THIS EXTENDED WARRANTY ALTHOUGH DEFECT IS THE SAME AND MAY IMPACT EMISSIONS.

TL* THE CONTACT OWNS A 2012 BMW X3. THE CONTACT STATED THAT WHILE DRIVING AT 65 MPH, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE BOLT HOUSING FOR THE CAM SHAFT DETACHED AND NEEDED TO BE REPAIRED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 95,000. THE VIN WAS NOT AVAILABLE.

I WAS HAVE ISSUES WITH THE VEHICLE HESITATING AND JERKING, AND GENERALLY NOT OPERATING AS EXPECTED. I TOOK IT IN TO BE CHECKED AS I WAS CONCERNED FOR OPERATING IT SAFELY. THE DEALERSHIP INDICATED THAT IT REQUIRES A SOFTWARE PATCH, AS THEIR IS A CODE ERROR, BUT THEY WILL ONLY FIX IT IF I PAY FOR THE PATCH. I TOLD THEM THAT IF IT IS A PATCH THAT SEEMS LIKE A RECALL - SOFTWARE IS NOT HARDWARE, SOFTWARE DOES NOT JUST STOP WORKING IF IT IS GOOD TO BEGIN WITH. IF WE ALLOW CAR DEALERS TO MAKE US PAY FOR PATCHES WHEN THEY MESS UP SOFTWARE WE WILL ALL BE PAYING HUNDREDS AND THOUSANDS OF DOLLARS FOR THEIR CODING ERRORS GOING FORWARD AS THE TECHNOLOGY CONTINUES TO INNOVATE. I AM ALL FOR INNOVATION, BUT I SHOULD NOT BE PAYING FOR THEIR CODING ERROR. MY CAR WORKED A FEW MONTHS AGO,...

ENGINE FAILURE AT 55K MILES WHEN THE CAR WAS LESS THAN YEARS OLD.

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. *TR
