2012 BMW 535I Fuel/propulsion System Problems

BMW N63 Engine Powertrain Issues 2012 535i The N63 engine, utilized in various BMW models including the 2012 535i, has been subject to multiple customer complaints regarding premature timing chain wear and other powertrain-related issues. This led BMW to introduce a "Customer Care Package," detailed in Technical Service Bulletin (TSB) B110614, to address the concerns reported by multiple owners and noted by the National Highway Traffic Safety Administration (NHTSA) under ID Number 11016414. A primary cause of the issue is accelerated timing chain wear. The N63 engine's design features timing chains that are prone to stretching prematurely. This stretching can disrupt the precise timing of the engine's valves, leading to a cascade of problems. As a consequence, owners have reported a variety of symptoms, including the illumination of the "drivetrain malfunction" warning light, noticeable engine noise, excessive vibration, and potentially catastrophic engine failure. The "drivetrain malfunction" message, in particular, is a frequently cited indicator of this underlying powertrain problem. To address these widely reported issues, the N63 Customer Care Package was implemented. This service bulletin instructs authorized BMW technicians to perform a series of diagnostic tests. The main objective is to detect if the timing chains have stretched beyond acceptable tolerances. If excessive wear is confirmed, the TSB provides a detailed procedure for the necessary repairs. This often involves replacing the timing chains and related components to restore proper engine function. Beyond the core timing chain replacement, the Customer Care Package also includes several proactive and preventative measures. Technicians are instructed to check and potentially replace other components, such as fuel injectors and boost solenoids, which may have been impacted or contributed to the engine's performance issues. Furthermore, the service includes reprogramming the vehicle's software

While driving car stalled, dropped speed and engine warning light came on. Fuel pump was needed. Had to have car towed obtained a rental for 11 days. Fuel pump out of stock. Immediately after fuel pump was replaced less than two weeks the thermostat had to be replaced. Another tow and another rental. I need to be compensated for stress aggravation and loss of use. Repairs and car rental and tow cost over $3500

ON OCTOBER 10TH, 2020 AT APPROXIMATELY 830AM, I WAS DRIVING WESTBOUND ON THE 118 FWY, MY 2012 BMW 535I SUDDENLY LOST POWER. I TRIED TO GIVE IT MORE GAS BUT IT WOULD NOT GO FASTER. IT IMMEDIATELY GAVE ME AN ERROR POINTING TO THE FUEL SYSTEM. I WAS ABLE TO EXIT THE FREEWAY SAFELY. AFTER BEING INSPECTED BY A CERTIFIED MECHANIC, IT WAS DETERMINED THAT BOTH OF MY FUEL PUMPS NEED TO BE REPLACED. THERE IS A RECALL FOR FUEL PUMPS FOR THE 2012 BMW 535I BUT MY SPECIFIC VIN NUMBER DOES NOT FALL UNDER THE RECALL. IT'S OBVIOUS I HAVE THE SAME ISSUE AS OTHER 2012 BMW 535I.
