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 federal safety agency 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

Confirmed by a Certified BMW repair center. Failure of Vanos Camshaft Gear Bolts. Recall has been issued for all 5 series models (and beyond) up to 2011, but does not include 2012 (5 series,) as it should. The Recall needs to be extended to include 2012 - 5 series models as failure of these bolts will cause immediate engine failure and could result in catastrophic crash, especially if driving at high speeds. I have contacted BMW of North America and they will not extend the recall until formal complaints, such as this, are received. My Issue with the Vanos Camshaft Bolts is currently being repaired (out of pocket) and I will share my invoice once received.
The headlights on the BMW 535 collect excessive amounts of condensation. If the condensation builds up, then the light does not function properly. The main safety concern is the malfunction of the turn signal. It will function in the rear of the vehicle but does not light up on the front in the affected headlight housing. Review of this problem on-line shows that this has occurred in many BMW vehicles and BMW also has issued a service bulletin for this problem (SI B63 05 16). As widespread as this problem is, I would think there would be a required recall for this service.
The front lights - water gets in impact visibility. The only repair is to replace the entire unit which is $2k per light. There is not other options. The adaptive warning sign does not go away due to this water.
While driving heard a loud noise and oil start pouring out the bottom of the car.. After getting my Vehicle looked at BMW dealership informed me that the drive shaft had broken and fell in the engine and caused a hole in the engine and damaging the oil pan also
Driver seatbelt fails to engage with latch. Latch does not positively lock when inserted. Safety risk is obvious and has rendered the car undrivable. This just happened and has not been inspected by dealer. I personally looked at it and compared with other belt points. to me, it looks like the small metal clip failed.
