2012 BMW 5 Series 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?

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.

“THE TIRE TREAD SEPARATED COMPLETELY FROM THE INNER SIDEWALLS. THERE WAS NO INDICATION OR WARNING OF ANY ISSUES, LOW PRESSURE, NO CONTROL PANEL WARNING, PULLING ETC. I WAS ENTERING THE HIGHWAY, ACCELERATED NORMALLY, THE CAR DRIVING NORMAL. THEN SUDDENLY, I HEARD A LOUD PULSATING VIBRATION SOUND AS IF THE TIRE WAS BLOWN OUT. I PULLED OVER TO FIND THAT THE TREAD HAD SEPARATED COMPLETELY ALL THE WAY AROUND THE INNER PART OF THE TIRE!!!”

“I had been having problems with my seatbelt alarm coming on for a while with nothing in the seat of the passenger and then as I was trying to turn in to park I heard a click from my steering wheel as if it didn’t want to turn and the driver seat restraint malfunction error popped up . Now my horn will not work as well . I’m told that the dealership is the only place it can be repaired. I’m worried that it will deploy on me while driving . I’m sure this is an issue others have experienced as well .”
