Is 2012 S car covered in recall/lawsuit

There is in fact a class action lawsuit against BMW for the timing chain tension failure on car with over 30K miles. The courts have awarded over 30 million dollars for damages. Google the title you posted and get registered for a claim. I would not do any repairs until talking with the attorneys. You may even get a loaner vehicle while they do this $2500 repair. If the timing chain fails entirely, it will destroy the engine too.

I also wonder if your original powertrain (engine) warranty should cover this. Sometimes a dealer will trick you into to paying for a covered repair, while also filing a warranty claim in order to get paid twice. Many ordinary people get greedy when there's money on the table. Be cautious.
