2011 BMW 3 Series power train problems

“Dealership performed VANOS bolt replacement recall on 2011 BMW 328i. Vehicle has 63K miles and is otherwise in excellent condition. Post recall, vehicle experiences unstable idle with rpm dipping low when stopped in gear during initial engine warm up period. Issue stabilizes somewhat but not completely gone once engine is at operating temperature. This is a safety issue with engine surging, hesitating, and potentially stalling when stopped at stoplight or intersections.”

“I recently brought my 2011BMW 328i in for recalls and a shutter noise. My vehicle is equipped with the N51 SULEV motor. I recently was not able to set monitors for smog due to a shutter issue. I was told by a reliable mechanic it was the torque converter, and it is covered under the SULEV warranty. I was shocked when Bob told me that the torque converter was not covered under BMW SULEV warranty. It clearly states that in the SULEV warranty and my car only has 123,000 miles. He proceeded to call my car "a can of worms" and told me the technician simply does not want to work on my car. I know for a fact my Torque Converter and Mechatronik are covered under the SULEV warranty. I was simply kicked to the curb. This is unethical and my car is not passing smog due to this issue which is illegal. Please help resolve my issue.”

“Transmission failure, while driving 45mph the car automatically downshifted then stopped pulling rolled to a complete stop was able to put into park turn car off then when tried to restart that is when the transmission failure light and notice came on the dash and radio screen. After that the car would not go into any gear or pull in any gear. No warning signs appeared before the incident.”

“Check Engine light is illuminated. VANOS exhaust warning codes are stored. Other vehicles with the same N52 engine are subject to recall 23V707. BMW indicates that this vehicle is not included but could be in the future. In the interim, we are faced with a $3500 - $4500 out-of-pocket expense (which will probably never be reimbursed) or the possibility of the events described in the recall, which include a crash. For the safety of drivers of other vehicles in this same series with this same engine, it is imperative that the recall be extended to all potentially affected automobiles. Thank you for your assistance. [XXX]”

“The contact owns a 2011 BMW 328I. The contact stated while his daughter was driving at an undisclosed speed, the vehicle shuddered, after which the vehicle lost motive power. The driver was able to coast to the shoulder of the roadway, where the vehicle initially failed to restart. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. The check engine warning light was illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance due to an error with the VIN. The failure mileage was 160,000.”

“i was driving to work and the car stalled in the middle of traffic when i slowed the vehicle down, the idle is rough and all over the place, car is very hesitant to accelerate and vibrates or shakes when approaching any speed. then the check engine light popped on and is still on, i’ve parked the car since the incident to do some research on what the cause could be.”
