general problems of the 2012 BMW 535

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.

Car stalled suddenly while in motion on a city street. Unable to restart the vehicle for 15 - 20 minutes while blocking the roadway. Transmission locked in park mode and override to neutral gear was not available. Inability to manually put gear into neutral poses additional problems.

I check engine light comes on about something with a fuel leak and BMW says it's something to do with admissions! I would like this to be taken care of please. This is a real issue. The other issue is the electric calipers get stuck and cause a big bang when u pull out of the parking spot when you first leave. Don't happen after that. The mechanic said this was the problem cause everything else looked fine.

Car stalled suddenly while in motion on a city street near a parking lot. Unable to restart blocking the roadway. Transmission locked in park mode and override to neutral gear was not available. Waited for tow truck while cars were blocked off. This could have been very dangerous if happened on a busy freeway or street. Inability to manually put gear into neutral poses additional problems.
