Reduced Propulsion Power
Certain 2016 and 2017 model year Chevrolet Volt vehicles, equipped with an automatic transmission (RPO MKV), may exhibit a condition where the driver notices a “Propulsion Power is Reduced” message in the driver information center. This condition is sometimes accompanied by the diagnostic trouble code P0A7F or a significant decrease in actual electric vehicle range. The driver may also notice the engine running at consistently higher power than normal to propel the vehicle and acceleration is slower than expected.
Dealers are to reprogram the hybrid powertrain control module 2.
Funny enough I had my 17 at the dealer in order to fix an annoying wind sound past 35mph(which they were unable to fix as it only occurs occasionally ugh) but according to the service guy as the campaign just started that day they were unable to apply it to my car...I guess i'll go to another dealership in a couple of weeks to apply this fix and to see if they can fix the wind noise.
Anyway, has anyone had the above happen to them?
