NHTSA Complaint #11493579 — 2017 CHEVROLET VOLT

Our 2017 Volt started experiencing a "Shift to Park" error message on November 2, 2022 when the vehicle is stopped and the transmission shifter has been placed in "Park". Apparently the microswitch responsible for detecting "Park" (GM part # 84955382) has failed and this appears to be a common defect in several models of Chevrolet. With this error message the vehicle will not turn off and the car cannot be secured properly (both of which are a safety concern). Our vehicle has less than 30K miles on it so it should not be a case of normal wear and tear causing the problem. GM has not issued a recall for this defect yet but we see there are several class action law suits looking to force them to do so. We also note that a number of consumers have reported the error progressing so that it occurs while the vehicle is in operation causing the driver to have to pull to the side of the road when transmission operation ceases. Chevrolet released document ID 5403533 on December 11, 2020, Bulletin #19-NA-206 due to the frequency of this defect detailing the parts needed to effect repairs for several models of Chevrolet. We have discussed this issue with our local Chevrolet dealer and they concur the vehicle should be repaired ASAP to avoid the progression of switch failure in the vehicle. Since the car is out of warranty and in the absence of a manufacturer's recall that will cost approximately $310. We will have this repair done tomorrow (November 15) and will ask the dealer to provide us the defective switch in case you care to inspect it.
