Owner Narrative

On May 24, 2026, while driving home from the Ocotillo Wells OHV Recreation Area toward San Diego, California, a drive of roughly 90 miles, a dashboard warning reading "Stability Controls Not Working" illuminated on [XXX] near Warner Springs in San Diego County. The vehicle is a 2026 Freightliner Cascadia chassis carrying a Renegade Classic 43CMD Super C motorhome body. The vehicle was approximately six weeks old with about 3,100 miles. I stopped the vehicle and attempted to clear the fault by cycling the chassis power; the warning did not clear. I completed the drive home with a passenger aboard, aware that the stability control system was reporting itself inoperative. On XXX I delivered the vehicle to Velocity Truck Centers, an authorized Freightliner service center in San Diego, California, recorded at 3,189 miles under service invoice XXX and warranty claim XXX. The technician recorded the cause as "ABS ECU SHORTED." His written correction states that he verified the ESC light was on, ran end-of-line code 1810/2 which did not clear the fault, confirmed the ESC module was mounted level and tight, unplugged the connector and drag tested all four pins and found them good, and concluded that the ESC module was shorted out. He removed the old module and installed a new one, which required calibration on a road test; the unit passed the road test. The replacement part is listed as ECU-ESC6, part number 446 065 095 0. An internally shorted electronic stability control module on a six-week-old vehicle with roughly 3,100 miles, on a motorhome of this size and weight carrying occupants at highway speed, is a safety concern. I am filing this complaint so the failure is documented for safety-trend and potential recall analysis. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
