Engine reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

The Valvetronic Actuator malfunctions. The malfunction may have been caused by a Battery Positive Cable that has corroded over time. The result is that the vehicle stops unexpectedly during acceleration. Driver safety and that of others is put at risk due to the vehicle suddenly losing power and stoping while being driven. The vehicle was evaluated by the dealer. Warning lamps were intermittent and inconsistent. To my knowledge there is no Valvetronic Actuator or Battery Cable specific warning lamps or messages. There was a 2017 recall for the Battery Positive Cable, but my specific VIN was not covered (by a few months). My VIN (1986 325I) should have been included in the 2017 recall.

I was driving on the freeway when all of a sudden a lot of white smoke started to come from the engine. The car instantly overheated and it shut off. My car had no problems until now. I called a tow truck to bring it home. I had many mechanics check it out and they couldn’t figure out why this happened out of nowhere. They all said the same thing that this car was in fixable and it’s not ever drivable no more. Then I received this letter from BMW saying that my car was on a safety recall list and they have no remedy.

THE PROBLEMS I AM HAVING WITH MY CAR INCLUDE: HIGH RPMS WHEN ACCELERATING, MASSIVE GAS CONSUMPTION WHICH I CAN PROVIDE BANK STATEMENTS TO PROVE, MASSIVE COOLANT CONSUMPTION, NUMEROUS OIL LEAKS, ROUGH IDLING, ENGINE RATTLING, FOUL SMELL OF VAPORS IN THE CAR WHILE RUNNING, AND CONSTANT CAR SHAKING. MY CAR WILL CUT OFF COMPLETELY IF THE A/C IS TURNED ON OR IF SITTING AT A RED LIGHT, SO IN RETURN I WOULD HAVE TO PUT MY CAR IN PARK WHILE SITTING AT RED LIGHTS. ALL OF THIS IS DUE TO THE PCV VALVE. THIS RECALL WAS NOT MADE AWARE TO ME IF THOUGH I TOOK MY CAR TO GET SERVICED AT THE BMW DEALERSHIP AFTER THE RECALL WAS ANNOUNCED. THIS IS WHY I ASKED FOR GOODWILL ASSISTANCE FROM BMW. ONCE MY CAR WAS TAKEN IN TO FIX THE RECALL BMW TOLD ME THEY WOULD NOT HELP FINANCIALLY WITH THE REPAIRS OF MY VEHICLE DUE TO THE FACT OF THE YEAR AND MILEAGE. CORPORATE TOLD ME THIS AFTER I HAD TO CHASE THEM DOWN ALL DAY BECAUSE THE DEALERSHIP TOLD ME THEY NEEDED A ANSWER BY 12PM AND NEEDED THE LOANER VEHICLE BACK. ONCE I RECEIVED THE ANSWER OF NO I ASKED CODY CAMPBELL IF THE RECALL WAS FIXED . HE REPLIED SAYING YES. I DROVE TO THE DEALERSHIP TO THEN BE SENT BACK HOME BECAUSE THEY SAID THEY WERE SEALING SOME OF THE LEAKS FOR SAFETY PURPOSES. I FOUND THIS ODD BECAUSE IF YOU LOOKED ONLINE AND STILL LOOK NOW AS OF 10:09PM ON 10/05/2019 THE RECALL STILL HAS NOT BEEN FIXED.
