When I was at my dealer Friday, he was telling me that chev says the motor is only good for 200K. They were putting in a new short block in one that had 180K, cost was 11,500 to do it. They were telling me they are seeing a lot come in with around 200K & motor/injectors are history.
I have service 4 wheel drive light come on from time to time. Dealer said they have a bulletin out on how to trouble shoot what is causing lite. He said sometimes it is easy to fix & some times it may take a day & 1/2. When he told me that I decided to keep driving it
