(First post from a fledgling 6 month Viper owner):
Three days after I picked up my Viper I find out that something deep inside that V10 was known to fail in a bad way. None of the dealers were ready to address it immediately, so the first 700 miles were fear? guilt? I was really wondering what the hell was wrong with me to get rid of that super reliable LS1 (30k=0 issues) for the expensive Viper. Good part was that it insured a nice gentle break in. Three weeks later the car goes in for three days to have the cam bolt fixed (more like checked) and fresh clean fluids replaced. What I got back was a car that everyone (dealership, friends, family, cops, anyone) expects me to drive hard. And for the next 5k the Viper was driven more like a GSXR750 (used to road race them) than a car. Rock hard suspension, hot and rough idling engine, summer heat, lots of redline, and lots of Brembo usually taxes a vehicle quickly. (Surprisingly?,) Viper is holding up fine. I mean nothing is engaging, fading, smelling, or sounding any different than the day it rolled off the showroom floor.
Interior/Exterior: I have noticed most of the “problems” that are published here. The headlights fog after a pressure washing (don't do that!). The windows with their “smart” sealing technology make mistakes, and when you slam that ultra-light door (which you have to) it can sound/feel like you almost busted your window. The weather sealant on the passenger door melted and started “stringing” all over around the paint. Wife puts hand/clothes on tar like mess, gets pissed. Wife notices a wormhole to hell like heat on passenger side foot well. Wife burns calves taking too long to get out of car (told her ya gota be quick!). Now some of those were not failures, but the end result: Wife hates the Viper, that's a problem.
Two trips to the dealership (sensor and oil) have taught me that the Viper techs don't work weekends or late. Two times a year I have to plan for half a day off to get my oil changed. I cannot imagine 20k miles a year in a daily driven Viper. But good for you or anyone else that can do it. I enjoy driving to much to ruin it with intentional overexposure. Despite problems posted on this board, I would NOT expect your Viper owning experience to be filled with FAILURES. The Viper is a solid high performance car. Problems . . . Not really a problem if you read/know about it first? More like a quirk . . .
