My 2014 Buick Verano had been throwing air intake codes so I replaced the MAF sensor which got rid of the engine lights. Months later the car died (no rattling, no weird noises, just instant shutdown while driving slow). It started right back up and the mechanic replaced spark plugs, air filters, and a couple sensors. He told me the timing chain is about to go and it’ll cost me $7-10k to fix today or the car will inevitable self destruct. The car never gave me codes related to timing or engine performance.

  1. Is it possible to give this diagnosis?

  2. Is that an insane quote?

Thanks

    Get a second opinion. But it’s entirely possible that a chain is in your future. That’s an interference engine, I don’t know about catastrophic failure but it’s entirely possible that aluminum engine could damage everything if you smash a valve into the piston. 8k sounds like a lot for a 4 cylinder motor tho. 8k would cover another motor.
