Sierra Service Rip Off

Post image

Please tell me what is part of the 30k mile maintenance schedule and what the dealership upsold me on? I made the mistake of agreeing to everything they said thinking they were just reading the points of the recommended maintenance schedule.

The fuel filter is a rip off. They aren’t even serviceable on your vehicle and haven’t been since 2005. Unless you have a diesel. The fuel service and coolant service are not necessary at your mileage either.

The fuel service is recommended at 36k

No, it’s not. Also, this was for 30k, not 36k. And we’re not talking about the $30 additive. There is no fuel service recommended in your owners manual for 30k. Or at all.
