The contact owns a 2021 Jeep Gladiator. The contact stated that while driving at an undisclosed speed, the vehicle made abnormal sounds. The vehicle was taken to the dealer and was test-driven; however, the dealer refused to diagnose the vehicle while it was covered under warranty. The vehicle was then taken to an independent mechanic, who diagnosed the vehicle and determined that the camshaft had failed, and the engine oil cooler housing needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 25,000.
