2012 BMW 535I

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

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.

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

3/23/2021 DRIVING ON I-94 IN MORNING RUSH HOUR WHEN ENGINE KILLED. WAS ABLE TO ROLL OVER TO THE MEDIAN BETWEEN AN ON-RAMP AND THE HIGHWAY BEFORE CAR STOPPED MOVING. CHARGE BATTERY LIGHT ON ON THE DASH AS WELL AS CHECK STABILIZATION WARNING. WOULD NOT TURN OVER AT ALL BUT DASH LIGHTS/WIPERS WERE ON (RAINING).

IT WAS FOUND THAT THE #2 PISTON RING CAME OFF AND JAMMED BETWEEN THE CYLINDER WALL AND PISTON CAUSING THE ENGINE TO SEIZE/NEED TO BE REPLACED. ONCE IT WAS REPLACED AND WHILE DOING A TEST DRIVE, THE MECHANIC FELT A VIBRATION AND THEY FOUND THAT THERE WAS MOVEMENT ON THE PASSENGER SIDE AXLE SO THEY REPLACED THAT AS WELL. THE CAR HAD 116.5K ON IT WHEN I PURCHASED ABOUT 2 WEEKS PRIOR TO THE ENGINE AND CV ASSEMBLY NEEDING TO BE REPLACED. JUST GOT CAR BACK YESTERDAY, JUST OVER A MONTH AND A HALF TO REPAIR.
