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

    So replace the timing chain asap. It’s either replace timing chain or timing chain breaks likely while driving and you have valves hitting pistons and destroys the motor. So as preventative maintenance get a complete timing job done. It’s that simple
