I will say that while I've had a few random issues with mine, it hasn't been anything too too crazy, and I really love it 5 years on and counting!
If you do get one, from my point of view these are some generally good things to know, in no particular order:
- The power window regulators and window bosses fail like it's their primary job, thanks to the design/materials. You will want to get DSE's replacement bosses and to have the regulators rebuilt/reinforced by Power Window Repair in AZ or someone else that does this same basic job. It's common enough of a failure that that company has a
Viper-specific page, and it is not a matter of IF they will break, it's WHEN they break. Do both of these things at the same time while you're in the doors, and it helps to add some sound deadening to the doors so they no longer sound like an 80's pinto when you close them. I would highly suggest having this done long before they inevitably fail. As of 2025, it's about $650 per side for the rebuilding and worth every penny to avoid the future headache.
- There was a TSB for it I believe, and I think it was predominately with early cars, but the rear window defroster has the potential to shatter rear windows when used. Essentially there is a grounding issue with the carbon rear deck lid that can occur. I would pull the fuse for this function until/unless you have that addressed if you get one. Personally, I pulled my fuse and never looked back since it's not something I will ever use anyway. There is a great video showing the situation
here if you're interested.
- I assume this is probably fairly understood, but in my experience there are very few places you really want to actually have work on these cars. I could probably say the same thing about almost any performance car honestly, but it's especially true in my experience with Vipers. You really can't just roll to the local Dodge place for some of the more Viper-specific things, and there are very few Viper techs left at the dealerships overall because Dodge discontinued the program years ago at this point.
- I'm really glad the parts initiative is helping bolster things, but there are still parts out there that just aren't available and you should be prepared for some level of that being true in perpetuity.
(not that this is really all that different than other low production cars)
- You may want to add front/rear tow points for any foreseen/unforeseen towing/trailering needs to simplify things.
(there are some very clean options to do this)
- You will need to have the ball joints greased somewhat regularly, every year or so in my case has been about right.
- For driving the car there are about two operating modes that are comfortable. Windows up with climate control on...and windows down. Compared to everything else I've ever owned, a ton of heat comes in the cabin unless it's on the colder side outside. No big deal at all IMO, but worth knowing before you jump in.
- Compared to tons of other sports cars in my experience, the factory seats arguably don't height adjust down far enough if you're 5"11 or over.
- In stock form I would argue the pedal box is kind of oddly offset and spaced, something you get used to certainly but is notable.
- Funny, but worth mentioning as it's probably my least favorite thing about the car. Be ready for a lot of random people to photo/video your car anywhere you go. On the highway, at a gas station, I genuinely get it happening to me everywhere. I've had a few flashy-ish cars, but visually the car is a real attention getter, far more than I've had with anything else which can genuinely be the good kind of annoying.
