2018 Chevrolet Equinox Electrical Problems

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.

1st Incident: Code P2138 - Accelerator Pedal Sensor In March of 2024 - driving on highway dashboard warning lights illuminated(traction control & reduced engine power) vehicle went into limp mode putting my family & I in danger due to traffic volume and speed on highway. Had to drive on berm at speeds below 25mph to exit freeway safely. Removed battery cable to reset computer. Taken to Serra Bartlett Chevrolet in Memphis- couldn't get vehicle to repeat error. 2nd Incident: Code - P2138 June 2024 - while traveling on highway same dashboard warning signals & car went into limp mode. Had to maneuver to the berm to exit the highway safely once again putting my family in danger at speeds below 25 mph exit. Vehicle was towed to Serpentini Chevrolet the Accelerator Pedal Position Sensor was replaced under the extended warranty. 3rd Incident - Code P2138 June 2025- while traveling on highway, same dashboard warning signals & car went into limp mode again. Had to maneuver to the berm to exit the highway putting my family in danger again at speeds below 25mph. Removed the battery cable to reset computer - was unsuccessful. Contacted Jeff Schmitt Chevrolet - had to drive the vehicle over 35 miles on the berm of the highway at speeds lower than 25 mph to get to dealership. Upon arriving they ran the codes and annotated the P2138 code. The next morning when the Technician checked the vehicle the computer had reset itself and everything was checking out fine, the code was still in the vehicle history . The sensor was under warranty and we inquired about replacement because the code showed failure, the dealership stated GM would not replace the part because it tested good. But I could pay to have it replaced if I paid for it. GM Service Bulletin No:074-06-04-019F clearly states they are aware of issues with this vehicle, yet I cannot get it repaired to my satisfaction It puts myself and my family under extreme danger while driving this vehicle on the freeway.

Driver side mirror sets itself to non useable position even when auto mirror option is not turned on. Everytime I shift gears the mirror positions itself to an unuasable position making it impossible to safely pull out from a parked position. It happens wether pulling forward or backing out. I can not seem to find any information on how to correct the issue. Other owners have reported the same issue but Chevrolet refuses to address the issue.

2/20/24 while coming to a stop at a stop light in a busy intersection, the car completely died/shut down. Hazard lights could not be turned on. No lights in car, no error message. no lights at all. RPM gauges remained in the same position as when the vehicle died. I was able to put it in park. After about 5 minutes the car was able to be restarted. It was not clear why it finally restarted. I tried to push break, push start button and push hazards. There have been similar incidents in the past but this incident took much longer to be able to restart the car. Those incidents the RPM gauge dropped into the off position in those other situations. The hazard lights were at least able to be turned on and I still had lights in my dash. This is a dangerous engine error that can not be replicated for service personnel to demonstrate the problem.

I have a 2018 Chevy Equinox. Was driving one day when the lights for service brake assist, park brake released, and traction control came on. The brake petal went extremely hard and was almost impossible to stop. Had the vaccum pump replaced. Drove for two-three weeks, same lights, brakes go hard off and on, vaccum pipe with sensor changed, only one week later same issues, another vacuum pump put on and oil changed due to metal from faulty pump in oil. We are now 900 dollars in repairs and no fix. Same issues over and over. GM is well aware of the issue with their faulty pumps and system but refuse to fix the issues and continue to put them in the vehicles which will lead to fatalities.

A message has begun appearing in my 2018 Chevy Equinox LT that states "Parking Brake Released". This message did not previously appear and seems to be a potential issue to fix. After doing some online research, I found 3 technical service bulletins for parking brake issues/messages for the 2018 Equinox on an automotive repair website. However, when I contacted the Chevy dealership and did a VIN search, there were no open recalls or any recalls for my car. I am not clear why other 2018 Equinox models have recall notices but my VIN number is not impacted by those notices, even though it was manufactured during the same year. Please help investigate if my car should be included in those TSBs and dealer repairs. The TSB numbers are: 20NA094, 19NA213, and PI1410B.

The sun roof shade is inoperable. The sunshade retracts, but does not go back into the roof so the whole shade hangs down. This completely blocks the view of the driver out the back window and is a severe safety risk. Even when the sunshade is "closed" the material hangs down, continuing to block the drivers view out of the back window. The shade has come off the tracks and unglued. The issue has been confirmed as inoperable and an internal fault in the roof shade assembly by a Chevrolet dealership and needing to be replaced completely. I have taken it to several other shops around my city, and have been informed that this is a common problem that is being referred back to dealerships for fixing. There was no prior warning sign, and my car has been experiencing this issue since July 2023.

I purchased my 2018 Chevrolet equinox on July3rd, 2018 with 2 miles on it. Current mileage 67,900 Stop/start system design defect. I have had to have my vehicle battery replaced 4 times in 4 years of ownership. The battery has failed again at 67,900 miles on 12/13/2022 which will be the 5th battery in its lifetime. My dealership said that due to the climate and road conditions where I live my stop/start system has been killing my battery cell every 16,975 miles causing my battery to fail. Chevrolet originally extended my warranty for 6months/ or 60k miles. They said they can no longer extend my warranty and that I’d be responsible for the next battery and future battery’s.

I have purchased a 2018 Chevy equinox. It was damaged on the back bumper (rebuilt title). The backup camera works fine but there is a side detection error that comes on everytime I start the vehicle. The shop replaced the entire harness however that did not fix the issue. I have read 1000's of complaints on this. My vehicle has 45000 miles. This is effecting my gas mileage as well as other safety features. I see this has been an issue in MANY GM models and it has been taken care ( special warranty) but not on a 2018 equinox as of yet. I want to report this problem and see if someone can look into all the other forums etc to see how widespread this really is. The light has came on a few times lately but only when I am parked and not going anywhere??? Thanks in advance.

Since I bought this car I have had to replace sensors like they’re going out of style. However I would like to report on 3 sensors that went out simultaneously on my vehicle in heavy traffic. I had the vacuum boost sensor for my master cylinder, my cam shaft sensor and my crank shaft sensor go out simultaneously. As a result my vehicle engine cut off completely (battery components still working) and I had zero control over my breaks. I had to use my full body weight on my break pedal to get the vehicle to stop. I was fortune to have been able to pull off into a parking lot. I have had to replace several o2 sensors on this vehicle. I didn’t think anything of having any electrical issues until this happened. My check engine light has stayed on for over a year despite clearing codes and replacing o2 sensors. We check periodically and the only code is usually for the o2 sensor. We can save the sensors we have replaced for inspection if necessary. I had a low engine power signal flash across the infotainment system just before this happened. I was in heavy traffic and I’m just fortunate I was able to get out of the way quickly enough before I hurt myself or someone else. The break issue and loss of power was actually terrifying
