GM Acknowledges Issue with Valve Springs on the 2020 Corvette

  • Admin
We've recently been hearing reports of owners picking up their brand new 2020 Corvettes from the dealer and getting 25 miles away when suddenly, the car goes into limp home mode and warning lights come on.

Upon further investigation, the root cause is a valve spring failure.

On September 22, GM issued TSB #PIP5752A: Service Engine Light misfire engine noise With DTC P0300 P0106 P0506.

The service bulletin includes 2020 Corvettes, Camaros, Silverados and GMC Sierras as well as 2021 Suburbans and Tahoes.
