Complaint Summary

ELECTRICAL SYSTEM

Owner Narrative

Since first test driving the truck in March of 2025, there was an issue with the ABS system warning coming on. When that happens, it also disables 4 wheel drive, electronic stability control, cruise control and trailer brakes. The first 3x it happened while NOT towing at about 45mph. Other times it happened while towing a 16,000# trailer which caused vehicle control issues when braking. I did however discover, in a panic, that the manual trailer brake lever still works. The cause of the ABS system shut down was determined to be code: C0037-2F (Left Wheel Speed Sensor Signal Erratic) It has be brought in to the dealer for repair at the following mileages: 4,478, 4,699, 13,790, 14,745 and 16,487 miles. Since then, the wheel speed sensor has been replaced along with the "tone ring" and other components. Most recently, it was determined that the main wiring harness was pinched and (2) wires for that circuit were shorted. The dealer ran (2) new wires outside the wiring harness. The new wire were also NOT sleeved as per SAE vehicle wiring specifications. They "said" they removed the fuel tank to access the repair, however forensic evidence does not support that. There is still undercoating on the bolt threads. It should have been disturbed or worn off when removing the fasteners. After the repair was made, the problem once again came back while towing a smaller 5,000# trailer on 10/4/26 at approximately 16,654 miles. The failure has occurred about 8 times now since the initial repair was made.
