The defect
Erwin Hymer Group North America, Inc. (Erwin Hymer) is recalling certain 2016-2018 Hymer Aktiv recreational vehicles, built on RAM Promaster chassis and equipped with a Continental kit (CK). The exhaust pipe may melt the rear bumper cover and the vehicle wiring in that area.
The risk
The exhaust heat can melt the taillight wiring, causing the tail light not to function, increasing the risk of a crash. Additionally, the exhaust heat can burn anyone that contacts the bumper cover immediately after the vehicle has been operated.
