I bought a brand new 2024 Jeep wrangler which has failed twice for the same issue with just 512 miles on the odometer. The first time it failed happened on the freeway at a speed of 70mph. Smoke started coming out from the rear of the vehicle impairing the traffic behind. I pulled over to the shoulder and noticed oil dripping from the exhaust and the rear undercarriage of the vehicle. I drove the car home fearing it could get on fire. The next day i took the car to the dealership where it was diagnosed with a bad pinion seal on the rear axle at 241miles on the odometer. At around 480 miles on the odometer, the issue came back. Everything happened pretty much the same; smoke coming from the exhaust, differential fluid splashed all over the undercarriage. Vehicle will be towed to the dealership for further inspection.
