NHTSA Complaint #11684213 — 2019 CHEVROLET EQUINOX

Vehicle experienced derating. Check engine light on. Called mobile repair service. 20 year mechanic. Replaced Pedal Sensor. Fail. Second visit replaced Throttle Body. Fail. He advised better to take it to a reputable shop. Did. Shop worked on it for 2 months and ended up replacing ECM. I finally had the unit towed to an Electrical Specialist in Longmont Colorado. They replaced Wiring loom between pedal sensor and car worked again. Drove car to Kansas and after about 300 miles, loud boom and messages on display. ECM engaged electric emergency brake hard at 79 MPH. WAS on cruise. At 20 mph car stopped messaging, and resumed normal operation. Pulled over, checked car. 50 miles from nearest city. cautiously drove about 20mph, then 30, then more until up to speed limit again. Worked fine 140 miles (needed a population center to get car fixed)) and it happened again. Limped car a few miles to repair in Salina, Kansas. ECM erased all miles, messages, etc. They could find nothing. my research showed the 2025 Equinox EV recall (We had replaced ECM and reprogrammed). I went to get car and risked driving, but without cruise. Warnings would come up, but car ran. No more emergency stops, but plenty of warnings. $3K in repairs and still problem. I believe current problem is electrical that Equinox is known for. The ECM/Reprogramming problem that activated the Brake is the issue here and previously reported by many. Extremely dangerous! Car has 50K miles. Was flawless driver until now. Note: Unit was Rebuilt Salvage. I bought at 1460 miles. Hit right rear, Replaced right rear sheet metal, Rear driveline on right side (Genuine GM parts), Replaced Hatch door. Inspected by state of Michigan. Reputable Rebuilder. Zero bad reviews. Hundreds of excellent reviews. P.S. Cannot take to Chevrolet - they universally refuse to work on car - not to even change oil.
