 Tl*the contact owns a 2001 gmc denali. everytime the vehicle undergoes a routine oil change, the contact has to place an excessive amount of oil back in the engine shortly afterwards. in addition, the battery terminal cables sporadically loosen and cause the alternator to fail. thirdly, while driving at various speeds, the 4 wheel drive spontaneously engages. lastly, the vehicle idles roughly when it is started. the vehicle was taken to the dealer on numerous occasions, but they could not correct the failure. the contact has copies of the vehicle's service history. the failure mileage was 90,000 and current mileage was 163,000.
