2019 Chevrolet Equinox

2 nights ago, my engine light came on. I purchased a code reader today so see what may be wrong, and code P0299, popped up. I’ve reviewed and saw there’s no known recall on the issue but there’s a known Technical Service Bulletin (TSB). In a Facebook group I saw, it says that some people have replaced and code P0299 is still populating. I’m buying this vehicle and I have barely had 2 years now and wanted it to last.

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.

Vehicle Information: 2019 Chevrolet Equinox VIN: [XXX] Mileage: [Insert your current mileage] Engine: 1.5L Turbo ⸻ Complaint Summary: Sudden and complete loss of brake assist while driving. Brake pedal became extremely hard to press, making it difficult to stop the vehicle safely. A warning message appeared on the dashboard stating “Brake Assist”. This happened without warning and made braking unpredictable and dangerous. If I had been driving downhill or in the mountains, I could have easily lost control or crashed. I was lucky to be on a relatively flat road when it happened. I inspected the vacuum hose and brake fluid level — both were normal. After researching, I discovered this is a known issue in 2019 Equinox models with the 1.5L turbo engine, related to vacuum pump failure or loss of vacuum supply to the brake booster. There are service bulletins and limited coverage programs (N192268490 and N182202780), but my VIN does not show an open recall. I believe this is a serious safety defect that could affect many vehicles not yet covered by the recall or service campaigns. GM needs to expand the recall and properly warn drivers before someone gets killed. Please investigate this problem and hold GM accountable for fixing this safety-critical issue.
