Electrical System Problems of Chevrolet Equinox - part 1

While driving on the interstate, the moonroof glass began opening without any input from the moonroof controls. The power sunshade was still closed at the time. I opened the sunshade manually so it would not interfere with the glass. After the glass opened, I was unable to get it to remain fully closed. When I was able to close the glass, it would reopen on its own several more times. I also heard a clicking sound during the repeated opening and closing. After this occurred, the power sunshade also stopped operating correctly. It would open fully, but when closing, it would stop approximately halfway and leave the front portion of the moonroof uncovered. It would not close completely. There were no warning lights or other dashboard indications during the incident. The only way I was eventually able to get both the moonroof glass and the sunshade to close completely was to leave the vehicle turned off for approximately two hours and then perform the moonroof reset/initialization procedure. After the reset, both the glass and sunshade returned to normal operation. The most concerning part of the incident was that the moonroof glass opened by itself while the vehicle was being driven, without anyone touching the controls.

My 2025 Chevrolet Equinox rs is experiencing critical active safety and electronic malfunctions. While reversing out of my driveway, the vehicle unexpectedly executed an aggressive "phantom braking" event, violently slamming on the brakes with no actual physical hazards or cross-traffic behind the vehicle. The reverse automatic braking (rab) and rear cross-traffic braking systems are hypersensitive and falsely triggering mechanical emergency stops, creating an immediate physical hazard and whiplash risk. Additionally, the google built-in infotainment system constantly suffers from communication freezes with apple carplay and media apps like pandora. Commands to select or play audio tracks freeze and fail to execute on the 11. 3-inch screen, indicating a systemic software architecture defect affecting the vehicle's dashboard modules. The vehicle has previously been out of service for an extended duration (30+ days)due to a broken telematics module causing parasitic battery drain down to 3 volts, along with multiple dashboard error messages. The manufacturer has been unable to permanently resolve these electronic and active safety failures.

From the very first day of purchase, the vehicle displayed a check?engine light, which I immediately pointed out to your salesperson. My concerns were dismissed, and I was assured that it was “not a big deal,” despite the fact that the issue was clearly present at the time of sale. Since then, I have spent substantial time and money attempting to resolve the vehicle’s defects. A mechanic spent six hours diagnosing and attempting repairs, yet the vehicle continues to display serious fault codes, including: evap system switching valve “b” performance / stuck open DC/DC converter voltage sensor “a” range/performance.

My car is a 2020 chevy Equinox with only 31852 miles. While driving today, all of a sudden the car started shuddering badly and stalled in the middle of the highway. Talk about a very scary situation. I pushed the car to the side of the road, and had it towed to a local shop. They found that the fuel pump control module had failed (p129f code). Upon doing some research, I found out that the 2021 Equinox had recalls issued for this same exact issue. I also found that the 2020 and 2021 Equinox both used the same part number fuel pump control module (13565638). Because of this, the recall should be extended to the 2020 chevy Equinox so that owners pay get the major possible safety issue fixed. Luckily, I did not get into an accident when this occured and honestly Chevrolet should be reimbursing me for the repair as this should have included in the safety recall for 2021 Equinox using the same part. I appreciate your attention to this matter and look forward to hopefully seeing the right thing done here. Sincerely, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My car seized while I was driving. It started fine and I drove about 10 min down the road and all of a sudden it seized. My car was towed to dealership. Onstar sent me a code p129f fuel pump.

The sunroof opens and closes without driver input. It initially occurred at startup but now also while driving (safety/security risk) . The sunroof switch has currently been unresponsive since 2025 . The issue is intermittent and has occurred multiple times. I have a pending diagnostic appointment and an open Chevrolet customer assistance case. * 2020 Equinox has approximately 55,000 - 60,000 miles on it and I'm also not certain if I have any warranty left that will cover the cost for this issue. Thank you in advance for your assistance with this matter.

About 3 weeks ago my battery completely died and I had to get 3 jump starts in one day. Upon replacing my battery I continued to experience a drained battery. Then my in-car wifi stopped working. I contacted onstar and they attempted to reset it which didn't work. So they escalated the issue to the highest department. I also had the battery and alternator tested and it showed that the battery and alternator were not the issue. It was decided that the problem was electrical. So I had all the electrical connections tested and it was determined that the issue was with the oem module.

Walked out of the car into the gas station came back out the brake pedal was locked up literally didn’t even wiggle at all couldn’t start the car I tapped it a couple times and then it made a horrible snap/pop sound and works fine for now.

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.

My name is [xxx], I live at [xxx]. I own a 2021 Honda passport, VIN ending in [xxx]. Two serious safety issues: 1. The multifunction camera behind the windshield has failed with codes [xxx] and u0416-f8. This is the same known defect that is the subject of a class action lawsuit. The dealer quoted me $1700 to fix it. I have only had the car for two years and I should not have to pay this much for a major safety failure. 2. The front passenger power seat moves backwards on its own and does not stop. On one occasion it trapped my young nonverbal autistic son in the car seat. I had to physically intervene to stop it from crushing him. I reported this issue to Honda USA customer service, and they told me to take it to the dealer. Both of these are serious safety defects. The seat issue especially is extremely dangerous for a child who cannot speak or scream for help. I am requesting that NHTSA investigate these defects immediately.

The starter on a new 2026 Chevrolet Equinox rs failed at approximately 6,500 miles. While the vehicle was being driven home during evening rush hour, it shut off at a red light and would not restart. The vehicle was stranded in the left lane of a four-lane highway. It could not be moved because the engine would not start, and the vehicle would not even roll in neutral, as the wheels were locked and would not turn. The disabled vehicle blocked a live travel lane in heavy traffic. The driver was a [xxx] new driver. Being stranded in a moving traffic lane during rush hour created a serious risk of a rear-end collision to the occupant and to surrounding vehicles forced to maneuver around the disabled car. Police responded because the vehicle was creating an active roadway hazard and arranged for a tow. The tow operator had to drag the immobilized vehicle onto the flatbed because the wheels would not turn. The failure was confirmed by an authorized Chevrolet dealer, which diagnosed a failed starter and replaced it under the manufacturer's warranty. There were no warning lamps, messages, or symptoms prior to the failure. The vehicle shut off and failed to restart without any advance indication. The vehicle has been repaired and is available for inspection. The failed starter was replaced by the dealer. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

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.

2025 chevy Equinox ev — telematics module failure & lemon law buyback. Brought vehicle in for a total telematics module failure (screen dark / communication dead). The safety comminication system did not work. The vehicle sat at the dealership for 40 days on backorder with no permanent fix or eta. Gm refused to guarantee or warrant the replacement module in writing, leaving me no choice but to force a full lemon law repurchase. Great driving vehicle when it works, but the software/module reliability and corporate customer service make it a high-risk purchase until gm fixes these supply chain issues.

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.

2017 Chevrolet Equinox premier certified pre-owned vehicle experienced multiple safety-related defects. 1. Repeated starting failures (electrical/battery/starter system): - March 17, 2026: complete battery failure, vehicle would not start. Aaa/gm roadside assistance called. Dealer inspected but could not diagnose root cause or explain battery drain. Preceded by unusually loud windshield wiper motor and engine noise (March 15). - April 13, 2026 (4:01pm): engine failed to turn over twice in parking lot before starting on third attempt. Safety risk: sudden starting failures create stranding hazard and risk of being rear-ended in traffic. 2. Water intrusion through headliner (sunroof/headliner/mic assembly): - April 15, 2026 (10:40-10:45am): approximately 1 ounce of water poured from headliner/radio microphone assembly directly into driver's eyes while driving on expressway.

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.

While driving vehicle during afternoon traffic, the vehicle started to sputter then die in the middle of the road, I tried restarting the vehicle, it would crank but would not start. I pushed the vehicle off the road and called a wrecker. I had the vehicle towed to the dealership for repair. After two days, they informed me that the fuel pump control module failed and would have to be replaced for approximately $600 I had no choice but to ok the charges, I spoke to the service manager because this part should be covered under the vehicle emissions warranty, but they said no, I did some further checking and it appears this part was a recall item! I contacted gm customer support and even after acknowledging the issue but stated it wasnt for our vehicle even though it was the same part and year.

While operating our vehicle on traveling at approx. 45 mph during mid-day traffic, the engine on our vehicle died and would not restart. We had no power steering and had to wrestle the vehicle off the road the check engine light was on and we tried repeatedly to restart the engine without any luck. We had the vehicle towed to the dealership for diagnosis and repair, it was determined that a fuel pump power control module had failed and that it would cost $599. To repair. We approved the repairs and then approached gm for reimbursement after discovering that this same part was recalled by gm ref # n252516900 which covered the make, model and year of our vehicle. We contacted gm customer relations and after speaking with them multiple times they approved a partial adjustment on the bill for approximately $150. I explained that according to their campaign notice and ongoing issues with this component we wanted a full refund and would not accept a partial payment of 1/3 our cost. Gm refuses to stand behind their product even though our vehicle only has 27,500 miles. I spoke with the service manager at the dealership, and he suggested I contact gm customer service and they should resolve the problem since this was an ongoing issue.

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 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.

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.

On Friday March 20, 2026, we traded in a chevy Equinox to get a newer model which is the VIN number we listed in this complaint. Driving home from the dealership the vehicle went from drive to park on its own (driving at 65 miles/hr) and my husband had to immediately put the car physically back into drive. Once we finally got the vehicle to our house, I went out to check it, and the vehicle would not even start. Every single light came on yet it would not start up. We called on-star and they couldn't do anything and told us we'd have to take it to the dealership. We finally got it to start up again, but the check engine light never went off. The next day my husband was able to get it started and immediately took it back to the dealership it was bought from, which it was actually transferred to from another dealership within the state, but on the way to the dealership we bought it from the car went into park on its own 5 more times, very dangerous and unacceptable. Once the car made it to the dealership, they could not even get the vehicle to shut off once they pulled in into the service area. My husband luckily is a professional driver, but is this was someone not as familiar or calm, this could have been a horrible catastrophe.
