GM Protection Plan (GMPP) Story

The GM Protection Plan (GMPP) offers several levels of vehicle service and maintenance contracts. When I purchased my Riv new in 1994, I purchased the GMPP Major Guard option with a $50 deductible for six years and 100,000 miles. Major Guard is the premium, comprehensive vehicle service contract and covered virtually every component of my vehicle, as well as alternate transportation and roadside assistance, including towing for covered repairs.

At that time, the manufacturer's warranty was 36 months or 36,000 miles (whichever comes first). My commute in the 90s took me over the 36,000 mile mark in less than three years. The dealer which had an excellent service department did all of my GMPP repairs over the years.

When I purchased the Riv and my GMPP plan, I never thought that I would still enjoy driving it over a decade later. After twelve years, I am now aware of a side benefit of my GMPP investment. The GM Goodwrench Limited Lifetime Warranty covered some of the repaired components.

Recently my A/C compressor went bad. I took it back to the dealer with my original repair order from 1999 and it was replaced with a new compressor at no cost. I checked part number on the work order on Gmpartsdirect.com and was surprised at the high cost of a new compressor.

After all these years of taking good care of my Riv, my Riv is now taking good care of me.
