NHTSA's VIN data lists these trims for the 2015 Viper. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 3 complaints with NHTSA about the 2015 Viper. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 1 recall campaign for the 2015 Viper over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Chrysler (FCA US LLC) is recalling certain model year 2013-2015 Ram 1500, 2500, 3500, 4500, and 5500, 2015 Chrysler 200, Chrysler 300, Dodge Charger, and Dodge Challenger, 2014-2015 Jeep Grand Cherokee, Cherokee, and Dodge Durango, and 2013-2015 Dodge Viper vehicles. The affected vehicles are equipped with radios that have software vulnerabilities that can allow third-party access to certain networked vehicle control systems.
Risk: Exploitation of the software vulnerability may result in unauthorized remote modification and control of certain vehicle systems, increasing the risk of a crash.
Remedy: Chrysler will notify and mail affected owners a USB drive that includes a software update that eliminates the vulnerability, free of charge. Optionally, owners may download the update to their own USB drive from http://www.driveuconnect.com/software-update/ or take their vehicle to a Chrysler dealer for immediate installation. In an effort to mitigate the effects of this security vulnerability, Chrysler has had the wireless service provider close the open cellular connection to the vehicle that provided unauthorized access to the vehicle network. This measure may not have been implemented on all vehicles and does not address access by other means that will be remedied by the software update. The recall began on August 25, 2015. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is R40.
Carmakers sent NHTSA 146 service bulletins and notices that cover the 2015 Viper, the latest on Aug 16, 2025. They tell dealers how to fix known issues.
The parts they mention most: electrical system (52), equipment (49), structure (25), engine and engine cooling (18), power train (11).
NHTSA hasn't opened a defect investigation that covers this model year.
