2020 CHEVROLET EQUINOX Electrical System Problems

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.

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

I’ve had the 02 sensor, maf sensor and a system update and my check engine won’t clear I’ve been dealing with this for over 5 months now. A Chevy dealership has had my vehicle and never informed me of warranty or recall issues.my check engine is throwing random code relating to the 02 sensor, lean code and multiple components having communication issues. Check engine will be lit and then clear on its own then return almost immediately

I am experiencing a recurring issue with my vehicle where the Park Assist system keeps activating unexpectedly, and the Check Engine Light (CEL) also comes on. I have taken the vehicle to O’Reilly Auto Parts for a diagnostic scan, and they reported no repairable codes present. Additionally, I visited Tires Plus, and their assessment was that if the light goes off on its own, then no issue is present that requires repair. Despite the temporary disappearance of the warning lights, the issue keeps returning, which raises concern. The Park Assist activation is not being manually triggered and appears without warning, often accompanied by the CEL. This inconsistent behavior suggests there may be an intermittent or underlying issue with the vehicle’s sensors, wiring, or onboard systems that may not register a permanent diagnostic code. At this time, no repairs have been performed due to both locations stating that no actionable codes or faults were detected. However, the issue continues to happen periodically, and I would like further inspection or documentation of the problem, especially if it worsens or begins affecting vehicle safety or drivability.

•Initial incident: July 2, 2025 •Recurring occurrences: August 8, 2025 Vehicle Issue Description: Several months ago, the vehicle’s check engine light came on. A diagnostic scan was performed at O’Reilly Auto Parts, but no error codes were detected. The vehicle was taken to an independent repair shop for further inspection. The shop found no mechanical issues and confirmed the vehicle was operating normally at that time. On August 6, 2025, the “Service Brake Assist” warning appeared briefly on the dashboard but turned off shortly afterward. The parking brake warning light also came on that same day, then went off. These warning lights reappeared intermittently on August 8, 2025. No repairs have been made as there are no active recalls related to these issues. However, it is noted that there are consumer complaints reporting similar problems. This raises concerns about potential intermittent or undetected safety system faults, particularly involving the brake assist system and parking brake functionality. Checked brakes again no issues determined per Bridgestone and Mavis.

Apparently my vehicle is experiencing the same fuel system and infotainment issues that others have been recalled for. As someone who has been diagnosed with car related PTSD; these issues have become very distressing to say the least. The infotainment system has shut off countless times while driving. I was traveling and missed my exit,I've also been abruptly been disconnected from important work calls and doctors offices. The fuel system is leaking fuel and the smell comes through the vents. As one of two people that utilize this vehicle that are asthmatic; this is very dangerous for us. Also my toddler aged niece cannot ride because of the harsh chemicals she would have to breathe in. Because of the leaking fuel, I'm terrified that it could breakdown anywhere or better yet worse catch fire while I'm driving. I have attached photos of the issues,unfortunately I can't upload the videos but I have countless in regards to the infotainment system and a video message from the mechanic in regards to the fuel system. If there is anyway I can send them also,it would be appreciated.

Engine reduced power, over acceleration as well as sluggish acceleration, wobbling on the freeway, electrical dashboard problems, tire sensor light comes on after getting it repaired. This vehicle has the same problems like 2021 -2024, reduced speed and couldn't go over 40 mph on a busy street with speed limited being 50 mph.

Twice my vehicle has stopped working where the shift to park messaging comes up and the car will not turn on or off. The vecle displays sec, low fuel, and park to shift messaging. The p for park to shift with the wrench underneath it appears. This issue happened once while I was in park and tried turning on my car and the other while I was in drive at a light.

On February 25,2025 I first noticed my engine light was blinking constantly while my service esc light and tc light was on while driving on the freeway. When I exited the freeway all lights went off. I had my mechanic check it out and he suspected a misfire because he ran the vin and said my vehicle had a history of a misfire. I was unaware of that because I wasn't given that information when I bought the vehicle a little over a year ago. I drove the vehicle approximately a month just around town and on March 26 2025 I was driving on the freeway and again the service escaped light came back on as well as the TC light with a line across the letters TC. The engine light did not come on on this occasion. I've read stories with many people with my same vehicle having the very same issue however I've searched my vin and there's no recall listed for my particular vehicle and I think there should be. I find it strange that the lights only come on if I'm on the freeway and I don't feel safe driving the vehicle with my son in the car while traveling outside of the city. I'm still.under warranty but I'm unsure if this issue is covered under my warranty.

ABS and breaks exploded at 67k miles and at 78k miles car shut off in middle of the street with no warning. Electric issues confirmed by mechanic.

On december 15, 2024 my car stalled out. on the middle of the road nearly causing me a collison. My vehicle for. the last month has been - what i assume is having electrical problems , my car is only 4 years old so im uncertain as to why it would be stalling out , this is also the first time that this has happen . i called my insurance company to file a report about my vehicle stalling out on a busy traffic road and all that was said was unless im in a collison there is nothing they can. do and if the car stallls out and i am in a accident it would be me at fault . I have one car which is the chevy equinox 2020. i cant afford to die nor be in accident that can potential put me in danger for a car that is only 4 years old .

I got this car in April of 2022. I am the second owner. Since May of 2022 every time I drive for longer than an hour the radio completely shuts off by itself and comes back on. I've taken it back to the dealership they drove for 5mins and stated radio did not shut off even though I told them they did not drive long enough. In January of 2024 while out shopping I go to start vehicle and it has power but won't start. I had the same issue in November of 2023 took it to dealership they stated nothing wrong with it. I called roadside in January 2024 power was on vehicle would not start. I ended up having to get vehicle towed to my home and had a mechanic come to me. Told me I needed a new motherboard. Paid for the new motherboard yet radio still cuts off. This has been an issue for far too long and is messing other systems up in the vehicle. I also had to have battery replaced and am still in need of four tires because the wheel spokes are rusted. A four year old car with this much trouble is not worth the headache.

PROBLEMS WITH ENGINE—replaced now transmission issues. UNKNOWN—everything that’s recalled I’m having those problems

Premature headlamp (low beam) failure. The light abruptly failed and it was acknowledged by the manufacturer that this should not have occurred. The failure occurred in October of 2023. Light fixture has since been replaced. The low beam bulb is not accessible for replacement in our vehicle. Instead the entire headlight assembly has to be replaced. The estimated cost for a single replacement was approx $2,600.00. After back and forth with the manufacturer they agreed to replace both headlight assemblies for approximately $1,900.00. A previous recall was issued for GM vehicles in the early 2000s that had similar premature headlight failures. This poses a safety risk because vehicles of this age are likely to still be financed and owners are unlikely to be able to afford a near $3,000 repair for a low beam headlight manufacturing defect. Please note the mileage on the vehicle was roughly 42k. There is the potential that owners will be forced to operate the vehicle with failed headlight(s) while the manufacturer refuses to fully acknowledge it is a manufacturing defect.

During the month of November while driving on Interstate 35 inTexas I attempted to administer my braking system during slowed traffic and they did not respond. The brake pedal became completely stiff and I had to apply incredible pressure to get the vehicle to slow down until I turned on my hazards and rolled to a stop on the shoulder. I did not have any alerts or warnings until I powered the vehicle off and powered back on to find my engine light on and the service brake assist alert on as well. I had it towed for service to which they replaced the vacuum pump, brake booster pressure sensor and brake fluid. Everything seemed to be working fine however a month later the same exact issue occurred. I took it in to the same place for service and had a brake inspection done and was told everything looked good and they were not sure what was wrong other than the ecm and ebcm were now reading codes. The issue is that this is intermittent with no warning and has been incredibly difficult to pinpoint the exact issue. This has also been incredibly pricey trying to chase an issue that appears one day and clears itself the next and lastly this has been terrifyingly frustrating as I do not know if i will have valid brake control or not on each ride. This issue could be life or death and was traumatizing as I had my son and mother in the car with me during the first event.

The brake assist warning light flashed and the electric components start blinking and the car went in reverse in traffic. The car then turnt off.

vehicle STALLED WHILE PULLING OUT FROM STOP. STRUGGLED TO RESTART AFTER STALLING. believed FUEL PROBLEM BECAUSE ENGINE TURNING OVER WHEN START BUTTON PUSHED BUT NOT SOUNDING LIKE STARTED LIKE NO IGNITION IN ENGINE. when IT DID START IT STALLED AGAIN. AFTER SITTING FOR A WHILE, VEHICLE STARTED. Several days later car soppt

discover that alternator is possible problem of stalling and car hard starting due to battery being low and reduced electrical power to use start. Wonder if power is reduce to fuel pump???

Car will not accelerate over 25mph…oil leaking from somewhere…car starts rattling and making putt noises…car now randomly blinks headlights and interior lights when idle flashing off and on…sunroof will not close but goes back—shade as well. Radio screens turns black and stays on while car is off. I HATE THIS CAR!!!

This vehicle starts glitching after exposure to rain. All of the gauges start going up and down, and every action required message pops up one after the other stating "Fuel Level Low, Shift to Park, Park Assist Off, All Wheel Drive System, Service Power Steering, ESC". The vehicle does this while driving at low to high speeds, even on the highways it has happened, the brakes are hard to push in while this is happening. This puts me and others in high danger if I cannot control the vehicle while driving. I have taken the vehicle in over 6 times to the service department of GM and not one time has anything been done. They have been unsuccessful in duplicating the problem every time I've brought it in even when it is occurring.

The equinox completely lost power (engine AND electrical) turned off while the vehicle was in drive on the road. Once at a complete stop, I pushed the brake and start button. The car attempted to start for a few seconds (clicking sound) then finally started back up. This is a major safety concern. Luckily I was able to get the car running again with no issues but if it had not turned back on, I would have been stranded on the road with no power to even put my emergency caution lights on. Thankfully I was not on the expressway going the speed limit or at a busy intersection. I could have been in a car accident because I was stalled with zero power to the entire vehicle. The vehicle was eventually towed to a Chevrolet dealership and the ECM was reprogrammed and the vehicle is back in my possession.

I DO NOT want that car. I want a car that is SAFE!!! REPLACEMENT CAR!!!

The issue is not consistent so dealership will not be able to solve the issue. No warning lights. No components have not been inspected by manufacturer. Issue occurs when it wants to. When in auto stop and vechile wants to start back up, vechile loses all power, windshield wipers turn on for few seconds then vechile starts back up. Seems like a reset. This is very dangerous when sitting at Inersections. This is happened several times.
