The On Star component failed mid- drive, resulting in loss of navigation and emergency calling. This happened before, parts were replaced and it has happened again.
2025 Chevrolet Equinox electrical complaints
Page 2 of 4: complaints 11 to 40 of 84, newest first, as owners wrote them.
I’ve owned this vehicle since new, and I’ve asked the dealership twice as well as contacted GM/OnStar customer relations. At speeds above roughly 65 mph, the interior turn signal indicator sound can’t be heard. I end up driving until the “turn signal left on” alert goes off, which is loud enough to notice. Since the sound comes from the audio system, I don’t see any way to change it through settings or aftermarket options. One of the safty issues is on crowded highways other driver attempt to get into my lane thinking I am about to change lanes again.
My telematics module for onstar is draining power from the car's battery which has been not allowing me to start after I turn it off without having to jumpstart it. Also when I do jump start it, the cruise control don't work and service messages pop up on my HUD. The dealership said it's undrivable due to safety concerns and the part is backordered for an unknown ETA.
Telematic module diagnosed to fail by the dealer service department. Replacement part is not available after 3 months, and not ETA from GM parts department.
Deconosco por que fue este en el sistema
My vehicle OnStar telematic module has shorted out the complete electrical system. This module is backordered. No time frame was told it could be months. Many GM vehicle have the same problem. The vehicle can stop while sitting or driving. This vehicle is unsafe to drive i traded it to the dealership. They will hold on to it until(if & when) they get the part.
Onstar module faulty causing parasitic battery drain unable to get a loaner car
telematic defective waiting 7 weeks still no eta... safety issue if battery loses power
While operating the vehicle on both interstate highways and local roadways, an intermittent malfunction occurs involving the All-Wheel Drive (AWD) system. The instrument panel displays a warning message stating, “Service All-Wheel Drive System.” When this warning appears, the vehicle automatically disengages from AWD and reverts to Two-Wheel Drive (2WD). Once this occurs, the system does not allow the driver to manually return the vehicle to AWD. This issue has occurred on more than three separate occasions. Notably, there have been instances where the warning indicator illuminated immediately upon starting the vehicle, prior to any extended operation. When the malfunction is present, the vehicle exhibits abnormal driving behavior, including a noticeable jerking or hesitation that feels consistent with a transmission-related issue. The failure is unpredictable in nature, with no clear pattern or triggering condition identified. This creates a significant safety concern, particularly when operating the vehicle at highway speeds or in conditions where AWD capability may be necessary for proper traction and control. An appointment has been scheduled with an authorized dealership for diagnostic evaluation; however, at the time of this report, the vehicle has not yet been inspected or repaired, and the issue remains unresolved.
For the second time the service high voltage system warning has came on first time it was updated the dealership said now it’s back on again A/C not working properly
While driving, a burning odor developed followed by visible smoke entering the passenger cabin from the dashboard/HUD area. We pulled the vehicle over and had it towed due to safety concerns. Dealer required dashboard disassembly to investigate potential electrical/fire condition but was unable to replicate the issue.
The contact owns a 2025 Chevrolet Equinox. The contact stated that the high-voltage system message was displayed. The vehicle was taken to the local dealer, where an unknown diagnostic test and repair were performed on the computer, but the failure recurred. The vehicle was taken to the local dealer again, where the AC receiver was ordered; however, the part ordered was the incorrect part. The dealer informed the contact that the part was on back order. The vehicle was not repaired. The manufacturer was contacted and opened a case. The failure mileage was approximately 6,065.
wiring harness on PCV Valve causes check engine light to come on as soon as it rains or gets wet. Dealer has tried multiple times to fix issue to no avail. The parts are on national back order and they can not get them. Dealer has told me that this is a know issue with this model year equinox.
The navigation system and the one-pedal driving system started malfunctioning. The navigation system began displaying a different location during remote driving, causing it to send me down a street against traffic. This issue has never been resolved and continues unabated. Then, while on the highway, when I needed to slow down, the one-pedal driving system deactivated, causing me to almost collide with another vehicle. This has happened more than three times this month. GM and Chevrolet just keep saying they'll call me back to resolve the issue, but they never do, and they refuse to fix it.
I was driving my car and a "service high voltage battery" message appeared on the screen and a message to reduce charging the car to 68%. The message coincided with the car having no cabin heat and no ability to defrost the windshield. The dealership says that the cabin heat and AC use the same cooling system as the battery and that any failure in the battery cooling system can cause a no heat/AC situation

On Monday, April 6th, I was turning into a parking lot and the braking system, specifically the anti-lock braking system (ABS) and electronic brake control module, appeared to malfunction. While driving, I received a warning indicating the ABS was off, and the brake pedal became soft with reduced stopping ability. The check engine light also came on. I had to coast the vehicle to a complete stop. The vehicle is available for inspection upon request. The loss of normal braking function significantly reduced my ability to stop the vehicle safely, increasing the risk of a collision. This created a dangerous situation for myself, passengers, and other drivers on the road. Brake failure at any speed presents a serious safety hazard.I am aware of similar complaints reported for this issue. My vehicle was towed to and inspected by a dealership where it sat overnight before being diagnosed; however, they were unable to reproduce the issue at the time of service. Despite this, the braking failure did occur and remains a safety concern. The service advisor told me to "bring it back if it happens again" and that it "lost communication with the EBCM" which sometimes happens. The vehicle has not yet been inspected by the manufacturer directly, police, or insurance representatives. There were no warning lamps or other symptoms of this problem prior to the failure.
When attempting to engage the Left turn signal, the lever has to be pushed down several times to "catch or engage" and stay engaged. Frequently it won't stay engaged and turns off before the turn is completed. (The Right turn signal works properly). This happens 8 out of 10 times on a consistent basis. The dealer shop supervisor and tech test drove it as well as another brand new lot vehicle and both did the same thing. They said that that's what they all do, and I should push down more firmly, which doesn't help. I'm in my late [XXX] , have driven new GM vehicles for decades and know how to use a turn signal. I have been in the middle of LH turns and the turn signal was not flashing to advise other drivers of my intent to turn. I believe that this is a significant and dangerous safety issue. I bought the vehicle new a little over a year ago and it currently has about 2500 miles on it. I am not sure when this started happening, but I started to notice it at about 1700 miles, 6 months ago when I started driving it regularly in place of my 2024 Chevrolet 1500 pickup. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
On four occasions while operating the vehicle down the roadway the dash screen and infotainment / vehicle information displays all have went dark off and reset causing disruption to vital information. Cruise control stayed active. It is unknown if the advanced safety features failed during the reset.
1 March, Onstar failed while utilizing the gps late at night. Stuck on side of the road until a passersby assisted me. 2 March, took truck to dealership, after 4 days said no issue found. Driving home, same issue persisted. Called dealership, told to bring back, 45 minutes away. Declined because was told no issue found. 6 March, morning truck completely dead. Called dealership and was told to have towed back to dealership. I declined because you didn’t find any issues when it was there. Following morning, 7 March, had truck towed to local dealership. After a week, was told Onstar telematics module failed and needs to be replaced. As of today, March 29, the part is on back order.
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.
The illuminated dashboard, center control console, and headlights suddenly turned off while the vehicle was in motion during a dark night. The blackout lasted approximately 10 seconds and I was unable to see to keep the vehicle on the roadway. After running onto the unpaved shoulder, I was able to fully stop the vehicle without hitting anything. All of the lights came back on and the dashboard showed a message that said "Auto shutoff". Then everything returned to normal. This problem hasn't been reported to the dealer yet, but will be discussed during an upcoming service to correct one of the other problems that keep occurring with this vehicle.
I purchased a 2025 Chevy Equinox EV last year out of the local Chevy dealership It is my first brand new vehicle and I’m the only owner, I have only had this vehicle for a few months and it has already showed me significant issues with the Electronic components Main issues I’ve experienced are: Randomly shutting off Randomly phantom braking On star capabilities not working No access to WiFi or any apps on the touch screen I.e. maps, music, settings, volume, radio etc. A/C/heating unit not working won’t get cold or hot just blowing air Issues with charging (almost left me stranded multiple times) not fast charging Issues with my Chevy app Took the vehicle to the dealership to get looked at they have had it for a week already and have not given me any update except that I will need a new onstar module. The vehicle is not safe to drive and I’m afraid that it will shut off while I’m driving at a higher speed I.e. on the freeway or that it will phantom brake while I’m on the highway which can cause a life threatening injury This vehicle has not been in any accident No warning lights came on except one message that said service emergency calling No warning messages prior to any of these events
The vehicle’s high-voltage battery system and propulsion system appear to have failed, causing a complete loss of power while driving. The vehicle is currently at the dealership for inspection, The vehicle completely shut down while I was driving on Florida’s Turnpike, creating an extremely dangerous situation on a high-speed highway. There was no warning prior to the shutdown, and I am currently pregnant, which made the situation especially traumatic and heightened the risk to both myself and my unborn child, as well as other drivers on the road. The vehicle has been taken to the dealership for inspection. As of now, the problem has not been reproduced, but the shutdown event is confirmed and documented by the dealer during the incident report and intake process. The vehicle is currently at the dealership for inspection. General Motors engineers or technical assistance center (TAC) may review the vehicle once the dealership reports the incident. No police or insurance representatives have inspected the vehicle for this issue. No warning lamps, messages, or other symptoms appeared prior to the sudden battery drop and complete loss of propulsion. The failure occurred without any prior indication while driving on the highway.
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.
am writing again regarding serious safety concerns with my Chevrolet Equinox EV RS. This is my fourth attempt to contact Chevrolet, as my previous emails have not received a response. These issues present a significant safety risk and require immediate attention.The problems I am experiencing include: Unintended lane movement: The vehicle shifts into another lane without any steering input from me. Brake response delay: The brakes fail to respond appropriately, causing a delay in stopping the vehicle.Steering wheel vibration: The steering wheel begins to shake after the vehicle exceeds approximately 55 mph.Steering wheel vibration: The steering wheel begins to shake after the vehicle exceeds approximately 55 mph.Due to these issues, I have almost been involved in three separate accidents, which is extremely concerning. These conditions make the vehicle unsafe to operate.I am requesting the following as soon as possible:A formal case number for this safety complaint.Immediate guidance on inspection or repair through an authorized Chevrolet dealership.Confirmation that these safety concerns will be investigated and resolved promptly.
2025 chevrolet equinox had, on numrous occasions, complete power failure. The vehicle had to be jump started more than once. The vehicle was brought in to the dealership, by the owner, with power failure concerns. The vehicle was towed to the dealership due to complete power failure concerns. The vehicle had brake pedal issue when power failure occurred. Meaning the brake pedal was not able to be pressed. Display signals: erroneous date/time, ABS, check engine, vehicle drive mode unavailable your vehicle may need service. Furthermore, on one ocassion a power surge was detected. The vehicle was diagnosed and an advisor stated the telemetry module is going out. However, the part that was replaced in the 2025 chevrolet equinox, several weeks later, was actually the telematic control module. The vehicle displays drive mode unavailable your vehicle may need service, even after telematic control module replacement beginning the next day after part replacement. The message displayed by the 2025 equinox occurs on a daily basis. Issues are october 2025 to present day.
My Onstar module is draining my battery. I have to constantly get my car jumped to get to and from. It's a danger to my job as a rideshare driver. I went to the chevy dealership today and they told me that the part I needed to order is on back order. How can a piece like that be on back order. This could potentially mess people's alternators and starters up in their cars.
Vehicle telematics module defect across the board that deactivates safety features from Onstar in case of an accident. GPS and Internet connection lost.
Just after Thanksgiving, my vehicle displayed a “Service Emergency Calling” message. I brought it to the dealership and they documented the concern, referencing GM bulletin PIP6077B, but no repairs were performed. On December 30th, while parking, I shifted into reverse and the vehicle would not reverse and instead moved forward. A “Service Transmission” warning appeared and the vehicle was towed. The dealer cleared the codes and released the vehicle without performing any diagnostics. About two weeks later, when starting the vehicle after work, several warnings appeared, including “Service Safety Restraint System,” “Forward Collision System Unavailable,” and a rear-seat alert despite no passengers. While driving, lane keep assist, lane departure warning, and blind zone steering assist were not functioning. The next morning, the vehicle suffered a complete electrical failure. It would not start, the screens stayed off, and the doors would not lock or unlock. The vehicle was towed again. The dealer replaced the battery, claimed it had simply died, and attempted to return the vehicle to me. I refused because none of the prior warnings were diagnosed, and I was told the codes “erase when the battery is changed.” After I demanded full electrical and transmission diagnostics, including a parasitic draw test, the dealership informed me the vehicle was unsafe to drive. They stated the OnStar/telematics module was draining the battery and the replacement part was backordered with no estimated arrival date. I was told multiple customers are waiting for the same part, which means this is NOT an isolated event and needs way more attention than it's being given. This defect results in loss of essential safety systems and complete vehicle shutdown, creating a significant safety risk.
