Onstar telematics module is defective and keeps draining the battery causing the need for multiple jump starts. The problem has been confirmed by don hewlett Chevrolet Buick on March 5th, 2026 and was told that the part is on backorder and that there is no eta.
I am on 20 service calls. Mine is currently having onstar issues screens glitching, apple carplay won’t connect, sensors on mirrors are going off nothing beside me, when I hit my breaks it keeps turning my emergency brake on and engine power reduced keeps coming on dash but the dealership is saying gm said my warranty is voided due to a aftermarket part.
Check engine light was on after just sitting in the snow for two days. Dealer is saying that it is a fuel injector and something with the gas. I hope this fixes it.
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.
The contact owns a 2025 Chevrolet Equinox. The contact stated that the vehicle was experiencing rough idling and sputtering at start-up. The check engine warning light was illuminated. The vehicle was taken to auto zone, where it was diagnosed with rough idling and fuel injector failure. The dealer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 8,000.
My daughter was driving and she said the check engine light started blinking and the car slowed down immediately. She had to press the gas to get it into a gas station.
The vehicle has experienced repeated failures of the integrated telematics system, including loss of gps location accuracy, loss of data connectivity, navigation malfunction, and intermittent failure of voice command and steering wheel controls. On one occasion, the vehicle experienced a complete display blackout while driving, during which both the infotainment screen and digital instrument cluster went entirely black. The condition has occurred repeatedly and persisted despite multiple repair attempts. The vehicle has been out of service for approximately 82 cumulative days for diagnosis and repair of these issues. An authorized Chevrolet dealership ultimately diagnosed a failure of the telematics control module, which was replaced under warranty. Following this repair, the same data connectivity failure recurred and was documented with photo and video evidence. The vehicle was returned to the dealership for further diagnosis. The failure is intermittent and may not be present during every inspection. The telematics system supports navigation, driver information displays, and emergency communication features, including transmission of vehicle location and system data. Loss of gps and connectivity may impair the vehicle’s ability to provide accurate location information during an emergency. The prior display blackout resulted in loss of driver information while the vehicle was in motion. The condition has been reported multiple times to authorized Chevrolet dealerships. Diagnostic procedures and programming were performed, and the telematics module replacement confirms a system-level failure. Recurrence after component replacement indicates the condition has not been permanently resolved. Prior symptoms included loss of gps signal, incorrect location, loss of connectivity, navigation failure, and intermittent driver assistance alerts.

We purchased the vehicle new. Within approx. 300 miles started to hear a bearing noise intermittently while driving. We returned to the dealership to have it diagnosed. We were advised that the could not duplicate it. A few days later the noise was brominate while driving at highway speeds. Returned to the dealer. We were told that it was caused by the active noise cancelling system and that they performed an update(per gm service bulletin) to the control module to correct it. Picked up the vehicle. Driving around town no issue. Driving at highway speeds the noise would come and go. On June 14, 2025. While driving on the highway at 70 mph the engine shut down. My wife and daughter were in the vehicle in the middle lane of a busy highway. The dash displayed "automatic braking engaged! while trying to get off the road. The vehicle brought itself to a complete stop. On the highway and engaged the parking brake automatically. This is unbelievable and extremely dangerous. How or why did some engineer think this was good idea for the vehicle to lock itself down on the road!.
My car threw on the check engine light and a note flashed on the screen and car just slowed down immediately. I had to press on the brakes really hard to get it home and then the transmission wouldn’t go in reverse. I took it to the dealer and they couldn’t duplicate the problem but said the battery contacts weren’t tight.

When accelerating to enter a road with high speed traffic the engine dies for a few seconds resulting in on coming traffic having to brake to avoid a collision. Then, the engine suddenly accelerates wildly. This problem occurs every time the vehicle is driven. The dealer service people has "tested" by driving the vehicle for 7 miles and declared there is nothing wrong. This is dangerous because the vehicle engine dies/stalls at a critical moment and if an oncoming driver isn't paying attention this could result in a collision.
The contact owns a 2025 Chevrolet Equinox. The contact stated that while reversing, the transmission remained in drive. The contact depressed the shifter to move. The contact stated that the gear shifter was sticking. The vehicle jerked, hesitated, and then stalled. The contact stated that the doors were locking and unlocking without driver input after an update was performed, and the keys became locked inside the vehicle. The service transmission warning light was illuminated. The telematics module, gps, and onstar were not working as designed. The contact stated that the onstar went into red and lost connectivity and was unable to locate the vehicle. The contact was concerned about driving the vehicle. The vehicle was taken to the local dealer, where it was diagnosed, and it was determined after further inspection that the battery was drained due to the telematics module draining the battery. The dealer informed the contact that parts were on back order. The vehicle was not repaired. The manufacturer was contacted and opened a case. The approximate failure mileage was 28,000.
Yellow check engine light comes on and off. Car isn’t 1 yr old yet im being told there is no recall yet or a fix.
Bought vehicle in October 2024. About 5 hours after we purchased vehicle the check engine light came on, dealership did reset and everything checked out to be safe and sent us on our way. Fast forward to January (do not remember date) check engine light came on again, this time took it to auto zone to hook the car up to the scanner, it did give an error code of p04fb which is a crankcase ventilation sensor. From auto zone we did take it back to the dealership and the had the same code as auto zone. Dealer ship did reset and acknowledged that chevy was “working on it” but no fix is available. Everything seemed to be ok until 6/5/2025 and the another time in June when the check engine light came back on and again the dealership reset it. Since June we have had the vehicle into the dealership once a month, July (not sure of date) and 3 times in August 8/26 8/27 & 8/29. The check engine light came back on and now we have to take it back to the dealership 9/2/2025. This is super frustrating and an inconvenience to have to take a brand new vehicle to the dealership every day. We have had the vehicle into the dealership a total of 8 times so far with a 9th visit on 9/2/2025 for the same issue when will chevy get this figured out?.
When the vehicle was stopped in an intersection, the vehicle would shift from d to p by itself. The check engine lamp was subsequently lit. I would not able to shift it out of p until I restart the vehicle several times. During such incidents, I was stuck in the middle of the intersection for a few minutes, impeding traffics and endangering myself and other motorists on the road. This problem first happened on September 20, 2024. The vehicle's odometer was at 1824 miles. The dealer made a repair. This problem happened again on October 14, 2025. The odometer was at 22065 miles. The vehicle is current still in the dealership. The vehicle was normal before such incidents. There was no warning light or any other noticeable anomaly before such incidents.
