Power Train Problems of Chevrolet Equinox - part 1

While driving on the freeway, my vehicle displayed a “service all-wheel drive system” warning and unexpectedly switched into two-wheel drive. This created a serious safety concern due to sudden loss of traction and control. Additionally, on multiple occasions while reversing, the vehicle abruptly applied the brakes without any obstruction present, displaying a message that automatic braking had engaged. My foot was on the accelerator at the time, and this created a sudden and unsafe situation. The vehicle has been taken to the dealership for repair, but due to the unpredictable nature of these issues, I no longer feel safe operating the vehicle.

The contact owns a 2018 Chevrolet Equinox. The contact stated that while driving approximately 80 mph, the vehicle unexpectedly decelerated. The contact pulled over to the closest exit and pulled over to the side of the road. The vehicle was turned off and then restarted; however, while attempting to drive forward or reverse, the vehicle failed to move. The contact inspected the vehicle. While inspecting the vehicle, the contact became aware that there was fuel leaking from the side of the engine near the high-pressure fuel pump underneath the vehicle. The check engine warning light was illuminated. The vehicle was towed to a certified mechanic, who diagnosed that the transmission intake failed, causing the transmission to fail. The transmission was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 168,053.

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.

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.

Multiple times (Friday, March 27, Monday March 30, 2026) we have had the 2020 Equinox fail to accelerate at green lights. The gas pedal is pressed to the floor and car is very slow to accelerate. It takes multiple depressions of the gas pedal to accelerate more than 10 mph. There are open recalls on certain VIN numbers from the NHTSA but mine was not on list yet appears to have many of the same concerns. Our local mechanic believes the details of recall bulletin 20v668000 should apply to our car as well.

Vehicle looses power and can very easily cause a bad wreck I've replaced multiple thing and it still does it I'm not sure what it is possibly the timing or something to do with camshaft.

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.

On February 23, 2026, while driving my 2026 Chevrolet Equinox ev home from folsom Chevrolet following a prior repair visit, the “service park assist system” warning illuminated, first intermittently, then after a few miles, continuously for the remainder of the 11-mile drive home. During the same drive, while reversing with no objects present behind or around the vehicle, the automatic emergency braking system activated and applied the brakes with significant force without cause. The vehicle was returned to folsom Chevrolet (repair order #559378, opened February 23, 2026). Diagnostic code u1126 was found — indicating the left rear short range radar sensor had lost communication on can bus 8. The sensor module was on national backorder, keeping the vehicle out of service for approximately two weeks. The module was replaced and programmed on March 7, 2026. Safety concern: unexpected activation of automatic emergency braking with no objects present creates a serious collision risk from following traffic. This failure occurred on public roads during normal driving. Additionally, the u1126 can bus communication fault is the same vehicle communication architecture implicated in the battery/electrical failure documented in repair orders #558923 and #559167, suggesting these failures share a common root cause in the vehicle’s electrical communication network rather than representing isolated component failures.

Engine went into limp mode with now warning. I recieved a reduced engine power warning and the vehicle lost acceleration on the highway almost leading to an accident. I had the car towed to coggin gm for diagnostic and was told that my throttle body has to be replaced. I was advised that this is common issue with this engine and notify due to a recall of older Equinoxes.

I keep loosing power and get the message "engine power reduced" and the car stops while driving down the road, sometimes it just stutters and won't maintain speed without the warning. I've had 2 shops check it out and can't find anything wrong. This vehicle has had all required maintenance done by the dealer since it was new.

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.

Incident date: February 10, 2026 mileage: 1,260 on the morning of February 10, 2026, my 2026 Chevrolet Equinox ev (1,260 miles) would not start. The instrument cluster simultaneously displayed three warning messages: 1)“service battery fault — vehicle won’t restart,” 2)“charging is unavailable,” and 3)“charge vehicle soon. ” the vehicle could not be placed in neutral and required dolly tow from my garage, as the front wheels were locked and could not roll freely. Aaa and I measured the 12v battery at 11. 8 volts. Aaa technician made attempt to jump 12 volt battery with no success. He made the observation that it was very rare for an ev not to start once the 12 volt battery was jumped. The vehicle was towed to folsom Chevrolet (repair order #558923, opened February 10, 2026). The technician performed a global reset, becm reprogramming, standalone radio programming, and a manual reset procedure. The repair order was closed with “confirmed no further concerns,” however the root cause — identified in the repair notes as a possible hv module communication fault — was never confirmed diagnosed or repaired. Seven days later (February 17, 2026, ro #559167), the vehicle returned to the dealer with overnight 12v voltage loss, starting at 12. 12v and continuing to drop. A parasitic draw test found an 11ma draw. After a second overnight test the dealer closed the repair order as “no concerns found” without identifying or repairing a root cause. Safety concern: a vehicle that cannot be started, cannot be charged, and cannot be placed in neutral poses a serious safety risk — particularly if such a failure occurs on a roadway rather than in a driveway. The inability to shift to neutral prevents the driver from clearing the vehicle from traffic. The root cause of this dual electrical failure has never been confirmed repaired despite two repair attempts.

The contact owns a 2020 Chevrolet Equinox. The contact stated that after coming to a complete stop, the vehicle hesitated while accelerating. No warning light was illuminated. The vehicle was taken to an independent mechanic, who replaced the front wheel drive transmission assembly, flushed the transmission fluid, and updated the transmission control module. The manufacturer was made aware of the failure and informed the contact that there was no recall associated with the VIN. The failure mileage was approximately 72,000.

While backing out of a parking space, with my 1 year old infant in the back seat, my vehicle became stuck in reverse and would not shift into drive or park. The vehicle became disabled and the warning dash stated to put the vehicle in park but I could not park or do anything else and couldnt take my foot off the brake or else I would continue reversing. Eventually I was able to at least turn the vehicle off but the vehicle remains with the shifter stuck in reverse after being towed. The lights and power to the vehicle remained on and this was not a battery issue. This was extremely terrifying for me especially with a baby in the car and getting it hooked up to the tow truck was also nervracking for all involved as the vehicle was in reverse. While there is not a current recall related to this issue on my vehicle, research shows that there have been in the past and this is a common issue for this vehicle.

The car automatically brakes when nothing is in front of you and all of sudden it slams on its breaks. This is going to cause someone to rear end you. The steering is all over the road and does. It feels safe to drive. Transmission gets stuck and revs really high until it catches and they say nothing is wrong. Safety sensors go off all the time and nothing is near you. Key fob not detected, multiple awd issues.

Safety complaint: engine stall/loss of power at highway speeds – 2014 chevy Equinox incident details: • the failure: while driving, the vehicle suddenly stopped responding to the accelerator. I was forced to navigate through highway traffic to the shoulder with no engine power. Once stopped, the vehicle would not restart. • warning signs: leading up to the event, the check engine light and battery light flickered intermittently. • diagnostic history: prior to the breakdown, a technician replaced the starter and checked the battery, yet the check engine light remained on. The engine exhibited high rpms (reaching 3,000+) during normal acceleration before the total failure. • safety risk: this defect caused a complete loss of propulsion in high-speed traffic, placing myself and my infant in immediate danger of a high-speed rear-end collision.

Transmission fluid leaking from the bolts.

I was driving south on interstate 55 near arnold missouri in adaptive cruise control mode at approximately 65 mph when the car braked suddenly and came to a complete stop on the interstate. Car would not go forward after stopping. Turned the car off and restarted and the car now would drive normally. Have not used acc since and car has behaved normally. Took the car to dealership in farmington, mo and they reported no error codes and no recalls. I had driven over 13,000 miles in the car without any incidents previously.

I am experiencing multiple unresolved defects with my 2026 Chevrolet Equinox affecting drivability, braking behavior, and vehicle structure/fit and finish. The primary issue is a persistent vibration, shimmy, or wobble during moderate acceleration from a stop. This condition is felt through the steering wheel, seat, and floor, and occurs consistently during low?speed launch and normal acceleration. In addition, the vehicle produces a snapping or grunting noise during hard braking, as well as rough and loud movement noises from underneath the vehicle during normal operation, which raises concerns about braking and drivetrain integrity. There are also body and interior fitment defects. The front passenger door does not sit flush with the rear door panel and appears slightly open when closed. The dealership service manager stated that correcting this condition would require removing and pulling the rear door panel outward so both doors align. The glove box door also does not sit flush when closed, and the service manager advised that replacement might make the condition worse. These concerns were reported to an authorized Chevrolet dealer. The dealer confirmed that general motors has acknowledged the acceleration vibration condition in a preliminary information service bulletin (pit6466) affecting 2025–2026 Equinox vehicles and advised that gm engineering is investigating the issue and that no repair is currently available. The combination of drivability issues, abnormal noises during braking, underbody movement sensations, and body misalignment affects the use, value, and safety perception of the vehicle. The vehicle has very low mileage, and several of these issues have been present since early ownership. I am submitting this complaint to document these conditions and request that NHTSA monitor potential powertrain, braking, suspension, and vehicle structure concerns if a defect trend exists. All of these defects have been acknowledged by the dealership service dept.

Forward collision system dint notify of an object infront , also breaks locked up when used . Air bags didn’t go off while a forward collision with a bus happened.

Automatic transmission slips and shutters/shakes when accelerating and going from a complete stop. Vehicle is not drivable long distances as the issue gets worse as the car heats up. No codes or sensors are indicating a problem. This is an ongoing problem despite having the transmission rebuilt. Issues first started a year ago and have been progressively getting worse.

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.

See attached document for complaint.

My 2013 Chevrolet Equinox (~132,000 miles) has a serious and unsafe oil consumption problem. I had a full oil change, and only two weeks later the dipstick was completely dry. The vehicle provided no warning lights, no low-oil indication, and the gm oil life monitoring system gave an inaccurate reading, failing to alert me to the critically low oil level. On November 25, 2025, while stopped with my foot firmly on the brake, the vehicle began constantly jumping and jerking forward as if it was trying to move on its own. During driving, I also began hearing a loud crunching, metal-on-metal noise whenever I accelerated or drove under 50 mph. Because these symptoms started suddenly and were severe, I took the vehicle to my mechanic the same day. On November 26, 2025, the mechanic confirmed that the engine had suffered major internal damage due to running with almost no oil. The timing chain and vvt components needed to be replaced. The mechanic confirmed that oil starvation caused this failure despite a recent oil change, and the inaccurate oil life monitoring system contributed to the hazard by failing to alert me to the critically low oil. This defect presents a significant safety hazard, as the vehicle can jerk unexpectedly, stall, lose power, or suffer sudden engine failure while driving, all without warning. I have since learned that excessive oil consumption and inaccurate oil life readings are widespread in gm 2. 4l ecotec engines. I am requesting that NHTSA investigate this safety-related defect.

The engine power reduced sensor came on and the gas pedal was hard to push so we took the car to a chevy dealership. We were told the code po299 was showing and that the turbo needs to be replaced ($4000). This is a very common problem and chevy even acknowledges that but they are doing nothing about it.

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.

After I purchased my vehicle, 2026 chevy Equinox rs, I noticed severe distortion on the front windshield. I had it replaced once, with the same problem. They were going to put another windshield in but we wanted to see it first, which was worse than the first two. I do not like the feeling of being car sick. Also, the transmission slipped once, while driving. It felt like it went into neutral and then back into gear. The dealer looked at it and could not find anything wrong. It was good for a few weeks and then it did it again.

Gm has redesigned the gear shift of the 2026 Chevrolet Equinox to be placed on the steering wheel. That's fine except engineers put it in the exact spot of where the windshield wiper lever traditionally is and made it look and act and move like a windshield wiper lever, which instinctively means you as a driver will hit that gear shift when it starts raining or when you want to trigger windshield wiper fluid. Doing so, as we experienced twice (once on a highway exit and another time on a major road) will cause the car to go into neutral since pulling the lever toward you (a movement that used to trigger fluid on the windshield) triggers the car to go into neutral. When you're driving on a major road, this is dangerous, slows the car, forces you to have to figure out how to get it back into drive and there's no obvious workaround for that. You can't come to a complete stop on a highway or a major busy road when in neutral and the car doesn't have easy/instinctive ways to send it back into drive. Numerous drivers have complained of this on reddit and facebook and presumably to gm. I sent a complaint to gm today. This is the first time in 40 years of car ownership that I've felt nervous driving a car because I'm worried I will cause a wreck because of poor design. There needs to be a workaround or alert to to this. Very dangerous.

Pulling into traffic car stalled without warning. Went from about 25 mph to a complete stop in approximately in less than 100 feet. Car sputtered with transmission grabbing intermittently as it jerked to a stop. Restarted about several times with similar behavior. (covered under 60,000-mile warranty (actual mileage ~55,000)). Replaced fuel pump driver control module to correct. No accident due to distance to on-coming traffic, but easily could have caused an accident during high traffic conditions.

As I was parked with the car running, my 2024 Equinox suddenly shut down and the check engine light came on. I tried to start it, but it didn’t. Someone tried to jump the battery, thinking it was that, but it wasn’t. I had it towed to the dealership and after 2 days they said the fuel pump power control module needed to be replaced. Unfortunately, gm did not have the part, but the dealership found one in another state and we had to wait several days for it to be mailed to them. After a week, once the part was replaced, they tried to start the car and realized that the original issue fried the battery, so they had to replace that as well. I was told that they had seen several customers with the same issue and wouldn’t be surprised if gm eventually issues a recall. They also said they couldn’t be sure the replacement part wouldn’t have the same issue. I did some research and found that gm has had this issue with 2019 - 2024 vehicles. Some customers reported that they were driving and almost got hit by other vehicles when theirs shut down. My car only had 18000 miles when this occurred. I no longer feel safe driving my car.

My 2024 Equinox was returned to the dealership on approximately October 1, 2025, due to a check engine light related to the torque converter. I required a rental vehicle during this time. I picked up my vehicle on October 10, 2025, and all repairs were covered under my extended warranty. I was informed that my rental reimbursement would be issued once I submitted the required paperwork. My safety and the safety of my grandchildren were put at risk loss of power and control-stalling, in ability to accelerate in traffic, gear slippage and over heating given the known history of torque converter issues in the Equinox—dating back as early as 2005—it is disheartening that gm continues to sell vehicles at premium prices while failing to properly support the customers who purchase them.

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.
