2025 Chevrolet Equinox

The vehicle became completely disabled due to a sudden battery drain at approximately 5482 miles. I purchased the car with 2553 on it in May. The vehicle would not start a few times and had to be towed to the dealership on Friday Dec. 26, 2025. The dealer confirmed that the OnStar/telematics module is malfunctioning and continuously draining the battery. The defective module is on backorder with no estimated arrival date, leaving the vehicle unusable. They also do not know if they have a loaner for me. This creates a safety risk because the vehicle can become inoperable without warning, potentially stranding the driver. The issue has been reproduced and confirmed by the dealership. Prior to the failure, the OnStar system stopped functioning, but no warning lights appeared on the dashboard. My Chevy App stopped working 26 days ago as well. I now have a Loan payment to make for a car that isn't even working and brand new. Dealership doesn't know a timeframe either.

I bought this vehicle brand new on January 18th 2025 and it has been into the dealership 3 times now for a backup camera malfunction. My rear traffic alert or any of my other safety features when backing up are not working. On several occasions the entire instrument display including my speedometer and everything has completely blacked out.

This complaint is to clarify and supplement a previous report. The issues began in August 2025, not September. Initially, the vehicle presented abnormal fuel range fluctuations, including while stationary, as well as intermittent “Key Missing” warnings while driving and display black spots. These issues were reported to dealerships and GM without resolution. Over time, the condition has progressively worsened, and additional symptoms have developed, including abnormal noises and, more recently, transmission hesitation during the initial gears, requiring me to reduce speed for the vehicle to respond properly. The escalation of these issues over time raises ongoing safety concerns.

- The telematics module is bad, resulting in vehicle having no connectivity (GPS, entertaintment system, updates) - The car has no other means of hands-free operation for navigation software (no CarPlay or similar phone projection technology) - GM is unable or unwilling to supply the parts for warranty repair. - It is illegal to use the phone while operating vehicle in my state (Florida)

The vehicle has ongoing and worsening electronic and safety-related issues. The fuel range and fuel economy fluctuate abnormally and frequently, sometimes even while the vehicle is stopped. The infotainment screen has experienced intermittent black areas/partial blackout while driving, affecting system reliability. Recently, the automatic transmission began hesitating during the initial gears, behaving abnormally and requiring me to reduce speed for the vehicle to respond properly. This occurs consistently. These issues have been reported multiple times to the dealership and GM with no resolution, and communication has stopped. I am concerned the vehicle is unsafe to drive and could fail unexpectedly.

On November 30, 2025, while driving my 2025 Chevy Equinox EV LS, the vehicle displayed a “Service High Voltage System” warning message on the center screen indicating an issue with the vehicle’s high‑voltage electrical system and that some driving and/or charging functionality may not be available. The high‑voltage battery and related components are still in the vehicle and available for inspection upon request. This fault could cause sudden loss or limitation of driving or charging capability, which may increase the risk of being stranded in traffic or in unsafe locations. Beginning in the first week of November 2025, the myChevrolet app has continuously shown a “Lithium‑Ion Battery – Schedule Service Now” alert under Diagnostics, even though no corresponding warning appeared in the vehicle until November 30. I presented the in‑app lithium‑ion battery warning to the Chevrolet dealer earlier in November; they declined to act on it, stated they do not rely on the app, and asked me to reschedule and return later, so the issue has not yet been reproduced or confirmed by a dealer or independent shop. The vehicle has not been inspected by the manufacturer, police, insurance, or others specifically for this high‑voltage/battery issue. The only prior symptoms were the persistent lithium‑ion battery service notification in the myChevrolet app since early November and, as of November 30, the in‑vehicle “Service High Voltage System” warning message.

Our OnStar Control Module on our 2025 Equinox started having connectivity issues. It failed to access apps and showed our location 100 miles from where we actually were, and drains the battery. We could not access OnStar to correct the issue. It continued to go off and on, until it completely failed. Researching this, hundreds of 2025 Equinox owners are experiencing the same issues. It is an extreme safety hazard as affected Control modules would send emergency personnel to an incorrect location in the driver is incapacitated in an accident. The module is constantly on back order for weeks. This needs to be looked at

I drive 20+ miles each way to work every day. Much of this drive is on highways, and currently the bridge connecting Ohio and Kentucky is down to three lanes with no berm. On a windy road with low visibility and a steep hill near my home, the car completely lost power and acceleration without any warning. I wasn't able to drive it completely off the road before it came to a stop and due to the loss of power was unable to move into neutral to push it and the hazards would not work. Thank God that this didn't take place on the bridge or with my family in the car. I made the decision to exit the car while it was still on the road and find a safe area in the grass where I could call for help. When I exited the vehicle, it locked me out and the only way to get in was through the driver's side door, which would put me back on the road in traffic and at risk. The electrical failure prevented me from opening the other doors. The car's complete system failure put my safety/life at risk and could jeopardize the lives of others if it wasn't investigated. To make matters worse when the tow truck came via OnStar they weren't equipped to move a car stuck in park or drive due to the electronic gear shift so they drug it with the tires locked onto the bed. After several days of testing the electrical system, the dealership found a loose wire and informed me that it had been fixed. I picked up the car and after a mile or so, the check engine light came on. I contacted the dealership to come pick it up and that's where it stands at the moment. My intention was to pass this on to my boys when they start driving, but this experience will alter that plan.
