Check Engine Light On problems of the 2015 Chevrolet Impala

When accelerating, the vehicle revs to high rpms and a loss of power to the wheels occurs. This happens most notably when accelerating to pass while cruising at speeds of 50mph and up. Check engine light appeared and code p16cf was given and tracked directly to the variable timing oil control valve.

Gm reimbursed me for one of two repairs needed to fix a problem that caused the check engine light to turn on. These two repairs were performed three months prior to gm's July 2018 letter advising me of additional protection for my 2015 Impala. I was denied reimbursement for the first fix identified by the car's computer to replace the evac canister vent valve solenoid costing $198. 77. I was reimbursed for the second fix to replace the purge valve costing $147. 55. In April 2018, gm had not identified any fix other than the ones identified by my car's computer. Therefore, both my repairs were performed to fix this problem and should have been reimbursed as fixes for the inoperative purge solenoid additional protection gm identified in its July 2018 letter to me.
