The 2013 and 2014 were acknowleged by Dodge to have had issues on a certain number of cars due to "debris" in the engine which people believe was addressing casting "sand" that was not completely removed. Those specific cars are identified by the r28 campaign, aka, recall. I have also read of 2016 and 2017 cars' engines failing. A respected Viper shop that does horsepower mods on Gen Vs has claimed that there are other problems with the engine's machining and assembly processes that lead to bearing failure (but not being an issue with the actual bearings being used as many misinterpret.)
