Leaking fittings on transmission cooler caused fluid to run out and seized transmission, while driver was in motion on highway, due to bad installation at factory. Upon inspection found 3 out of 5 trucks with same problem. Warranty coverage was denied by eaton and peterbilt claiming driver error.

The contact owns a 2015 peterbilt 579. While driving 55 mph, the driver noticed smoke coming from the passenger side of the vehicle. Upon further inspection, the driver noticed that the front passenger side axle was on fire. The driver was able to extinguish the fire. In addition, the brake pedal was depressed but failed to respond. The contact did not disclose if a police report was filed. There were no injuries. The vehicle was towed to a dealer but was not diagnosed or repaired. In addition, the failure recurred and both front axles caught fire. The fire was extinguished. The vehicle was towed again to a dealer but was not diagnosed or repaired. The manufacturer was notified of the failures. The failure mileage was 43,000.

We purchased this truck on 4/09/21 and on 4/13/21 while it was parked at the yard it cut on fire by itself, no external cause other than something wrong with the truck that we were not told or aware. It looks like it could be some defective parts from manufacture that have 3 recalls that cause fire. I would like to conduct an investigation and find out the official cause. We lost our retirement funds and now nobody wants to be responsable for. A witness recorded a video and you can clearly see where the fire was coming
