    This vehicle about 6-8 weeks ago started throwing codes for all systems above (over 100 codes). This issue affected all systems of the vehicle including but not limited to the speed and braking of the vehicle, plus the fuel system and adaptive driving systems. We took it to the dealer Performance Peterbilt in Tifton, GA. They cleared the codes and said they resolved it by replacing a NOX sensor. We left the repair shop and within 50-100 miles the exact same issue started up again. We took it back to the same shop, they worked with Paccar and determined it needed a new ECM (Computer), this was changed out and still did not resolve issue. They then changed out the main wire harness. This resolved some issues but not all issues. Now the repair dealer is stating it needs a dash wire harness. This vehicle has relatively low miles 500K and has only been serviced by Peterbilt dealers through it's life. This issue causes the vehicle to accelerate and brake randomly plus many other issues by stopping power in hauling. We have another IDENTICAL vehicle which is now doing the same thing but have not brought it into the shop yet until manufacturer can get this 1st truck fixed properly to ensure safety.

    On 8/10/2024 our sleeper berth hvac fans abruptly quit working. After checking fuses we noticed the fan control switch was hot. After removing the panel that the switch is held in we noticed the HVAC Fan Control switch (Part# 599-5000) was charred, upon removing the switch from the plug we observed the actual plug is melted, and one of the wires on the wire harness has charring of the plastic insulation. This could have very well caught fire. I am going to have to replace the wiring harness as re-pining the plug will not solve the issue of the wire being burned and the insulation being charred. There was no warning lamps, occasionally the fan would turn off then resume.

    Front axle begins popping and making metal to metal noises when hitting bumps and or turning. We took it to the shop and they found the nuts to the U-bolts that hold the leaf springs to the front axle had begun backing off and were out of torque spec. Upon receiving the truck back the front end no longer made this noise. Approximately 8 months later we are hearing the same metal on metal and popping noises that we heard previously. We have also noticed similar year Peterbilt 579's with this same noise and popping so this isn't specific to our vehicle.
