Most know my story. A failing PCM for many years. Numerous trips to the dealer and they could never diagnose it because it was an intermittant problem. Long story short. I finally decided to replace the PCM as all other possibilities had been exhausted. The Envoy has never run better and I plan on keeping it a long time.
As these get older, I'm thinking they will be harder to get parts for. I'm thinking while there is still a supply of PCM's out there for a reasonable price to get a back up one to have. The last one I purchased from PCM of N.C. has worked flawlessly. It was pre programmed with my V.I.N. and all that had to be done was the security reset once it was installed.
Has anyone else had a PCM fail? Is it common enough that I should keep a spare on hand? Thanks for any input.
