My 2011 Volt frequently shows "propulsion power reduced" after the battery has been depleted and on restart. This affects performance, acceleration and thus safety for several minutes until the system rebalances itself. This condition began back in 2015 several years ago but is first noted in dealer's records at 101,000 miles. The car has 142,000 now. It has been in the shop several times asking for this condition to be repaired as the problem became more frequent. It appears to have had the software update you reference in your bulletin that may cause the problem. The condition is identical to that in your recall 18215, reference number N172130460. Please contact me for more information. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
