The 2013 Viper (fifth-generation SRT) is a low-production hand-built supercar with an 8.4L V10 making 640 hp. These are weekend toys with low annual mileage; most issues stem from sitting idle, heat management, and the hand-assembled nature of early SRT build quality rather than high-mileage wear.
Transmission Mount Failure (Manual Tremec TR-6060)
Common · medium severity
Typical onset: 15,000-40,000 mi
Symptoms: Harsh clunking on 1-2 or 2-3 shifts under hard acceleration, Excessive shifter vibration at idle, Visible transmission sag or movement when rocking the car in gear
Fix: Replace both rubber transmission mounts (front and rear). The rear mount tears due to torque shock from the V10. Requires lift access, exhaust work for clearance. 3-4 hours labor plus alignment check.
Estimated cost: $800-1,400
Cylinder Head Cracking / Exhaust Valve Issues
Occasional · high severity
Symptoms: Coolant loss with no visible external leaks, Misfire codes on specific cylinders (often #8 or #10), White smoke at startup after sitting, Overheating under sustained high RPM (track use)
Fix: Early Gen-5 heads (2013-2014) can crack between valve seats or leak internally, especially if overheated. Requires head removal, crack inspection, valve seat repair or head replacement. 20-30 hours labor for full head-off service. Some owners upgrade to later Gen-5 revised heads during repair.
Estimated cost: $8,000-15,000
Infotainment System Failures (Uconnect 8.4)
Common · low severity
Symptoms: Touchscreen freezes or reboots randomly, Backup camera displays black screen, Audio cuts out or Bluetooth won't pair, Climate control becomes unresponsive (controlled via screen)
Fix: The 8.4-inch Uconnect system is prone to software corruption and hardware failure. Flash updates help temporarily; most need radio head unit replacement (part is still available from Mopar). 1.5 hours labor for R&R and programming.
Estimated cost: $1,200-2,000
Fuel System Vapor Lock / Heat Soak Issues
Occasional · medium severity
Symptoms: Hot-restart stumble or extended crank after sitting in heat, Rough idle or stalling when fully warmed up in traffic, Fuel smell in cabin or garage after spirited driving, Check engine light with lean codes (P0171/P0174)
Fix: Fuel system runs hot due to engine bay temps; fuel lines near headers and poorly-shielded fuel rails cause vapor issues. Aftermarket heat shields, fuel line rerouting, and phenolic spacers under injectors help. Filter replacement and purge valve check required. 4-6 hours for full heat mitigation.
Symptoms: Rattling noise from front of engine at cold start (lasts 3-5 seconds), Check engine light with cam/crank correlation codes, Rough idle or misfires that come and go, Metal shavings in oil (catastrophic failure)
Fix: The 8.4L uses hydraulic tensioners; low oil pressure or extended oil change intervals cause tensioner collapse and chain slap. Requires full timing set replacement (chains, guides, tensioners). Engine-out recommended for access; 25-35 hours labor. Preventable with strict 5k oil changes and quality synthetic.
Estimated cost: $6,000-10,000
Differential Fluid Overheating (Track Use)
Occasional · medium severity
Symptoms: Whining or howling from rear end after extended high-speed runs, Burnt gear oil smell after track sessions, Clunking on deceleration (bearing preload lost)
Fix: The factory rear differential lacks a cooler; track abuse degrades fluid quickly and can cook bearings. Add aftermarket diff cooler, switch to 75W-140 synthetic, and change fluid every 10k or after each track weekend. If bearings are damaged, full rebuild with bearing and gear replacement. 8-12 hours labor for rebuild.
Estimated cost: $2,500-4,500
Owner tips
Change oil every 5,000 miles with full-synthetic (0W-40) even if driven minimally; the V10 runs hot and degrades oil quickly.
If storing for winter, use a battery tender and start monthly to circulate fluids; fuel stabilizer is mandatory to prevent varnish in injectors.
Inspect transmission mounts annually; these fail early and cause expensive secondary damage if ignored.
Track use requires upgraded brake fluid (DOT 5.1), differential cooler, and post-session fluid inspection; these are not turn-key track cars without prep.
Buy one if you want a raw, analog V10 experience and can handle $2-3k annual maintenance even at low miles; avoid early 2013s with head issues unless well-documented or already repaired.

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.
Consequence: 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.
