There were a couple of TSBs and the recall on the headlights ( a reflash ), and keep in mind the 7/70 is just a powertrain warranty which covers only around 200 items ( average car has 5000 ). The CamBolt check , was in 2004, and only involved a small number of cars. Few had any issues, but it was a precautionary check to make sure the bolts were tight. There was a recall/TSB on the 2003s for the valves , as a few over 200 were not angle cut, leaving them down on power. Most of these were replaced with the correctly cut valves.
Overall, compared to most vehicles, the list of TSBs , recalls , etc. is actually quite light for Vipers.
Sincerely,
Bill Pemberton
