2012 BMW 5 Series engine problems

“car engine timing chain guides are faulty and there have been lawsuits that were settled and no recall on the actual part with drivers still having issues with the N20 engine now getting quotes for over 15,000. is this not an incident where it’s not the fault of a driver but manufacturing? This needs to become a recall for all N20 engine timing chain and guides as the faulty part is causing complete engine failure. seems very deceptive when a BMW only last 100,000 miles.”

“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…”

“I had just purchased a car but a month ago I was driving to lunch and I was at a stop sign when the light turned green I started to go the car started shaking and smoke was coming out of the front under the hood I had just an oil change so I took it back to the oil change shop. They could not figure out why the engine blew and I had to take it to a different BMW shop where I have to purchase a rebuilt motor and pay for the repairs. I can request all records from the automotive shop if needed.”

“The drivetrain disintegrated. Car started running really rough, and then just stopped completely. Would crank but would not move. Yes, it is available. Car would barely go, and then just stopped in the road. I had to have it towed to a mechanic. No, I had not received a warning of this possible hazard. No, it was not inspected by any of the above, but was inspected by numerous mechanics. Yes, drivetrain light/warning came on, as well as, drive at a slower rate when the car started to drive roughly. The turbo also went out on the car. May 28, 2024”

“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.”
