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.

Twice, while driving in falling snow away from home, the front wipers did not work properly when switched to lo or hi. They behaved as if set to intermittent wiping. The intermittent wiper setting worked properly to adjust the wipe interval. But setting to lo or hi did not cause the wipers to go constantly. As far as I could tell, the arm pivot area was clear enough for them to wipe. The problem went away on its own without restarting the car. It happened again a few days later when parked in a driveway.

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.

Received a report from local auto repair and they found that the oil main seal is leaking. Issue happened in the highway and car automatically turned off the engine. I was not in an accident as there was no one else on the road and I was able to push it to the side. When the car turned on the wheel was stiff and hardly moved to the right or left. The warning received before the shut off was the service stabilitrack issues and when checked all oil completely depleted from the vehicle.

In fmvss 138, it says that the tire pressure monitoring system will warn drivers of under inflated tires. My tpms system failed on my my19 Chevrolet Equinox around 49,000 miles and no longer warns me of underinflated tires for all four tires. To fix it I would have to pay out of pocket costs starting at $732, per the dealership, on a safety critical system that should not fail at 6 years/49,000 miles. There is no recall issued after a check of my VIN. Since 1974, the oem has had a responsibility to provide a free remedy for safety defects and noncompliance. In 2015, the free remedy was changed from 10 years to 15 years by the fast act.

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.

Engine power low.

- 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).

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.

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.

My Equinox ev telematics module does not work. Prevents the use of navigation features and onstar navigation features.

While driving under normal conditions, the vehicle’s blind spot monitoring / side object detection system frequently activates alert warnings when no vehicle is present. These false alerts occur intermittently and are more common during rain or wet road conditions. Over time, the repeated false warnings create a “boy who cried wolf” condition, where the driver becomes conditioned to ignore or discount blind spot alerts. This undermines the effectiveness of the advanced driver assistance system (adas) and increases the risk that a real blind spot warning may be ignored during an actual lane change. The alerts activate without any adjacent vehicles visible, causing confusion and distraction. This results in hesitation, aborted lane changes, and reduced driver trust in the system. The issue has occurred multiple times and is not an isolated event. The dealer has acknowledged the concern but advised that no repair or software update is currently available. The manufacturer has acknowledged the issue but has not provided a fix. I believe this represents a safety concern because a safety warning system that generates frequent false alerts can condition drivers to disregard legitimate warnings.

At 5 am in the morning the car suddenly failed and indicated it was an engine or transmission failure in the middle of a four lane major intersection in a downtown area. It was dangerous due to the darkness, and poor visibility. I had to abandon the vehicle as it was dangerous to stay with it while waiting for police. I could have been injured (as could others) due to its sudden failure in the intersection of a busy roadway. Chevrolet dealership states it is the fuel pump driver module. The car is currently at the dealership for repair. There were no warning lamps, messages or other symptoms of the problem prior to the failure until the car suddenly lost power. Once it lost power the engine light lit up and shortly after I had exited the vehicle, I began receiving messages from "on star" telling me that there were engine or transmission problems. Meanwhile I stood in the pouring rain in an unsafe neighborhood, leaning out into traffic to try and stop cars from running head on into my car for over 30 minutes waiting for police.

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.

On th, Nov 6 ~1700, the 25 Equinox ev being driven encountered an electric drive failure and brake failure, including friction brakes. This Equinox ev is essentially still brand new with 3900 miles and no accident history. The vehicle was driven off the eb sr 528 exit ramp to narcoossee rd in orlando and driven to the stop light at the wb on ramp. After the light changed and began driving, the vehicle console reported an exception with drive assist. At this time the driver attempted to slow down to take stock of the situation and the vehicle accelerated, at which time the driver took their foot off the brake pedal and attempted to identify a place to take the vehicle off the roadways. Thankfully a stoplight at mccoy rd was green and the driver continued through that light and while attempting to brake, the vehicle accelerated instead. The driver then coasted, maneuvering the vehicle was into the vista palms commercial center. The vehicle, unresponsive to braking, propelled through a stop sign into the kohl's parking lot at which time the driver began looping around the lot until the weight of the vehicle brought the motion down. While the vehicle was stopped, it rotated through warning messages indicating. . Forward collision, brake assist is reduced, steering assist is reduced, then finally service transmission now unable to shift soon. The vehicle was towed by aaa to autonation Chevrolet airport in orlando. Technicians found codes u1610 and u1639, and found k160 connecter unseated. It was reseated and greased. The concern is that this should have been locked and unable to be unseated. Is this an indication of manufacturing problem or operating problem? all braking was dysfunctional. How can we be certain that this was not a one off event?.

While driving my 2017 Chevrolet Equinox, the vehicle repeatedly displays diagnostic trouble code p2138 (throttle/pedal position sensor voltage correlation). The vehicle suddenly enters “reduced engine power” mode without warning and loses acceleration while driving. This occurs daily and multiple times per day, both on highways and local roads. When the issue happens, the vehicle will not properly accelerate and loses power unexpectedly. This creates a serious safety hazard, especially in highway traffic, as I am unable to maintain speed or accelerate to avoid other vehicles. I have had to maneuver carefully or move toward the shoulder to avoid potential collisions. The throttle body has already been replaced; however, the problem continues to occur. The defect has not been corrected and remains ongoing and reproducible. I am currently [xxx] pregnant and drive this vehicle daily for work and to transport my [xxx] child to school. The unexpected loss of power places both myself and my child at risk while operating the vehicle in active traffic. This defect presents a significant safety concern due to repeated and sudden loss of engine power while driving. The vehicle is available for inspection upon request. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Got the Equinox brand new on March 2025. Few weeks later had to take it to service/dealer with backup camera problems and it had to be replaced. It started to have speakers issues due to a very loud humming sound while driving. Also window from drivers side runs slower than the rest of windows. The visibility through front glass is non existent when raining due to the angle. Transmition started slipping and started to have a check engine light pop up and had to take it to service again. . . And finally at the beggining of November had to take it to service due to a sudden battery drain. She wouldnt turn on for no reason. The defective module is on backorder with no estimated arrival date, leaving the vehicle unusable. Its been there for 2 months now. . . They provided a loaner. Everything has been confirmed by dealer. They said that had 3 pages of codes pop up to be fixed.

My vehicle was not able to use the onstar properly and after researching numerous complaints I guess a faulty or bad onstar module is a common issue among gm owner especially within the first 12 months of owning the vehicle. Why is this problem not being recalled or compensated to the hundreds of individuals paying out of pocket for this malfunction which is close to $1000? why is the module dying or breaking so easy and in such short period of time. This is hazardous to my family because my disabled child can make driving scary some days. Not knowing I have the emergency onstar button available, or knowing where I am in case of an emergency is a severe issue for me hence why I purchased a new vehicle and made purchasing onstar services a priority for my family. Also the wifi feature helps my child to communicate with me and tell me any issues since she is non verbal and needs her device. Also not being able to use the app to lock the vehicle in case I forgot is a safety concern to me because sometimes I need to know I locked the car or that I know where the car is at all times. This onstar working or module mishap needs to be fixed and stop unconvincing people’s lives and those they love. People who are forced to fix this issue of the onstar not even getting a signal or being able to call onstar is dangerous! this who feel protected by the services and willing to purchase a vehicle just because of this should not have to pay up to $1000 to fix this issue especially in the first year! I can’t believe the amount of people who affected by this companies faults and carelessness. A recall needs to be put in affect and the modules/wiring need to be reinforced and installed more properly.

The vehicle’s display screen intermittently goes black, rendering the rearview camera inoperative. This failure significantly impairs rear visibility and creates a safety hazard while reversing.

Infotainment center is not operable. Had a diagnostic test completed by certified dealership and it is found that the infotainment center and radio is not operable. Contacted general motors corporate office. $47 was offered to go towards the $950 to fix it it. They did not offer any reimbursement for the $204 paid out of pocket for diagnostics fee that I they advised me to get after filing complaint. Due to the malfunction of the infotainment center and radio other safety issues have stopped working. Such as the onstar safety feature, the phone in case of emergency, the turn signals and also the safety features on the rear and side view mirrors, car length warning, and back up camera. Was advised from the dealership that all of these functions have ceased working due to the failure of the infotainment center and the radio. Unable to hear any warnings. Made a complaint with ohio attorney general's office and general motors' response was only to provide me 5%, which is the $47 towards the dealership invoice. There reason was that due to the mileage they cannot assist further than that. Its not about entertainment of the radio. I feel this is a safety hazard on so many levels, and it is not caused by simple wear and tear or any fault of the driver. This is a safety issue that I want addressed. This should not be a financial burden that the consumer should carry by themselves.

The vehicle’s heating system operates intermittently or takes an excessive amount of time to produce heat, reducing cabin visibility and comfort in cold conditions and creating a potential safety concern.

One time (so far) the screen behind the steering wheel that shows the gear and speedometer did not turn on when we started the car. We were able to back the car out of the garage and park it in our driveway. This is a safety concern because we could have driven the car in that condition - without a working speedometer. We are worried that the screen will turn off while we are driving.

Some kind of malfunction with the sunroof caused the sunroof to open without me knowing. Only the glass part opened. The top part of the car on the inside right above the door was wet down toward the side near the brake pedal fuse box that was filled with water. Sunroof will not close. Was told we needed to replace motors.

The contact owns a 2025 Chevrolet Equinox. The contact stated that while stopped at a traffic sign, the accelerator pedal was depressed; however, the vehicle stalled. The contact stated that there was no warning light illuminated. The contact stated that the transmission automatically shifted to park(p). The vehicle was towed to a service station and the vehicle was refilled. The contact was able to start the vehicle, and the message "auto shut down" was displayed and a 5-minute countdown was started, and the vehicle turned off. The contact was able to restart the vehicle and drove to the residence. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 13,000.

Rear spear tire compartment full of water. Sunroof drains leaking into rear fuse box. Fuel pump and fuel pump module failing when driving. Turbo locking up from oil seal 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).

Rear tailgate. Borrowed vehicle from a friend for a trip. When opening the tailgate with the external switch it opens all the way and immediately comes back down about 12 inches or so then it immediately goes back up and immediately comes all the way down. My wife was almost trapped between the bottom of the tailgate and the floor of the storage compartment. When I tried it, I tried to hold it up when it started down for the second time and it was impossible for me to stop the tailgate from closing. It substantially overpowered me. There is a probability that it could have broken her back or strangled her. Even more so if she was packing the car by herself. I exerted all my strength trying to stop the tailgate as I indicated before. I have not contacted anyone about this situation. The vehicle has a little over 84k miles and is in excellent condition. When I called my friend about the problem she said she was aware of it and is living with it because it would cost over $1,000. 00 to fix it. I know she bought it used from ferman Chevrolet in tampa a few years ago. I was hoping to get it fixed for her before returning the car to her.

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.

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.

The contact owns a 2018 Chevrolet Equinox. The contact stated that after having a software update to the ecm following the notice of an unknown recall, on several occasions while in reverse, the vehicle failed to reverse as intended. The contact stated that the vehicle seemed like it would accelerate forward. The contact had to push the vehicle for the vehicle to reverse. The contact that while pressing the ignition button on several occasions, the vehicle failed to start. The contact continued to press the ignition button, and the vehicle eventually started. Additionally, when the vehicle was started, the "parking brake release" message was displayed even though the parking brake was not engaged. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 101,000.

When trying to disengage cruise control, with button on steering wheel, brakes locked up going 75mph on the interstate. Would not unlock until I physically pressed brake pedal. If I had not been able to control the car, we would have been sent head first into the concrete barrier wall. Also, when trying to start car or put in into gear, it tells me to "press brake" when the brake pedal is pressed as far as it can go. Radio will randomly cut off and screen goes blank. Trunk button on drivers door does not open trunk without pushing it minimum of 5 times. Sometimes it takes more.

My vehicle has been at the dealership for over a month for an issue with the hvac system. The technician and gm engineering support believe the problem is related to a faulty acuator, which requires the entire dash to be removed for repair. (see pictures) this is extremely concerning for a new vehicle with very low mileage. An hvac acuator failure in a brand new car should not occur, and the repair is invasive- involving disassembly of the major interior components. I am worried this will lead to creaks, rattles, or compromised fit and finish afterward, as well as potential damage to electronics, airbags, and trim panels. In addition, this problem appears to be widespread among other 2025 Equinox owners, based on multiple reports in owner forums describing identical hvac noise or clicking problems linked to acuators. Gm has not yet issued a recall or service bulletin addressing it. Given the scope of disassembly required and the frequency of similar reports, this should be reviewed as potential design or component defect affecting vehicle reliability and safety systems (defrosting performance and interior air management).

The vehicle had a fault in its gps and it also had no communication with emergency assistance. This also caused battery problems that generated on two occasions that the vehicle did not start.

Vehicle lost power / cel illuminated.
