2025 Chevrolet Equinox Powertrain & Transmission Problems

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

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.

Was told bad fluid pump at 35k. Replaced. Car broke down 30 seconds from dealer. New transmission to be replaced now. Parts on backorder. Will be without car for “months”. No symptoms prior to failure. No warning lights. Car just wouldn’t start.

Transmission fluid leaking from the bolts

OnStar Module malfunctioned, has been diagnosed and awaits identification of specific type of module to determine if one is available or if it is one that will be on back order. The safety of myself and my family was put at risk, along with others, when vehicle braking system randomly activated and slammed on the brakes despite clear highways all around, almost causing us to be rear-ended more than once. This has happened prior to 12/01 several times randomly but we assumed the sensor was sensitive and was picking up something we couldn't see, however this was not the case in this situation. The battery keeps going dead and needing jumped and there are numerous warning messages/lamps. Dealer service department confirmed OnStar module failure and need for replacement, has not yet reproduced braking issues. Vehicle is currently at dealership service department for inspection and was deemed unsafe to drive at this time. Dealer stated they had no loaner vehicles to supply and instructed us GM would reimburse up to $45 daily for rental at Enterprise, so a rental vehicle was obtained and placed on waiting list at two different dealerships for loaner vehicle. WiFi and Navigation System originally quit working, then car battery started dying and requires being jumped multiple times if not driven within 8 hours, Received alerts off and on of "Lane Change Alert System Off", "Service Parking Break", "Adaptive Cruise Control Temp Unavailable", "Service Power Steering", "Service Electronic Stability Control", "Service Transmission Now, Unable to shift soon", and cruise control/Lane assist etc quit working. We became stranded in another town and had to purchase a portable jumper. Dealer currently has no anticipated repair date.

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.

Vehicle rolls back very often when in drive. Even holding down the brake at a hill then hitting the accelerator it still rolls back. When in cruise control and I take over it also tends to make the vehicle jump when the vehicle takes back over. Overall harsh riding. Feels like it’s all coming from that CVT. Dealer says that it may be an issue but can’t replicate it unless it stays there with them for a while until they can replicate the issue. There have been incidents where I’ve almost rolled back and hit other vehicles due to this cause. The vehicle has not been inspected by anyone. No warning lamps or anything on the vehicle

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.

Telematics module stopped working out of nowhere and drains my battery to my vehicle. Had to have the vehicle towed to nearby dealship. Huge safety hazard as it is essentially the brains to my computer. App doesn't work without it, battery doesn't work and can't even get inside vehicle with key fob. Please issue recall.

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.

My new 2025 Equinox RS AWD ran out of gas entering a 55 MPH highway. I tried to roll to the shoulder, and I came to a stop half on the right shoulder and half in the lane. When a 2025 Equinox RS AWD won't run, in this case because it is out of gas, there is no way to shift the car out of Park and into Neutral so it could be rolled out off the road, or on to a Tow truck ramp. When a 2025 Equinox RS AWD isn't running, it's locked in Park, and in order to move it needs to be jacked up and set on wheel dollies, for all four wheels.

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 car vibrates hard, like being on the rumble strip, but only while driving about 1.7 rpm to 2 rpm and only sometimes. The transmission light came on. The dealer said it was leaking and fixed it. A few days later, the vibrating is back. It's at the dealer again. Still don't know what's wrong. I only have 4,500 miles on the car so far.

8 speed transmission will not shift to 8th gear at highway speeds. It will shift at a lower speed which makes merging onto an interstate dangerous. The vehicle gets better fuel mileage if it will use 8th gear. For it to use 8th gear on the interstate you must merge onto the road at a much slower speed than posted speed limit and then very slowly accelerate to posted speed limit which puts driver at greater risk of an accident.
