2018 Chevrolet Equinox electrical problems

ELECTRICAL SYSTEM

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.

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.

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.

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

I see that this isn't a recall but is affecting many models of chevy from year models 2016-2019 with the gear selector assembly. The issue is the harness, solenoid, or sensor in the gear selector assembly is faulty and when trying to put the vehicle in park, the vehicle thinks it is NOT in park when it IS. Then, when you leave the vehicle, the interior beeps at you and electricals stay on as well as headlights/tail lights and will drain the battery unless you disconnect the battery. I don't see why this hasn't been recalled? I see SOOOO many people with the same issue and I've read that some dealerships are reluctant to fix because they can't "duplicate the problem" The problem is, you can't just buy the gear selector harness assembly wiring harness since it only comes with the whole assembly itself. So this should indeed be a recall because the average person isn't going to be able to figure this out and they shouldn't have to pay since it is happening in what looks like thousands if not tens of thousands or more vehicles.

The vehicle first started having a cigarette residual smoke smell in it during the summer of 2019. It was right after a good rainfall, but we didn't know what to attribute it to. We called the local Chevrolet dealership and they weren't sure what it might be either. The odor would come and go over the last couple of years, but we couldn't figure out what it was from as none of my family members smoke. Then my husband went to run errands in my vehicle during a heavy downpour and heard water running inside of the car. He found water coming out of the fuse panel on the driver's side in the rear hatch (video available). He started removing the wet stuff in the rear hatch & when he got down to the spare tire compartment, he found it was filled with water. He also smelled the cigarette smoke-like odor like 10 times stronger than before & realized that it was due to the felt-like pad in the spare tire compartment being soaked in water. We again called the local dealership & they weren't sure what the problem might have been. My husband & stepfather did research and found out a lot of Equinox owners were experiencing the same issue & it had been determined that it was due to the sunroof water drainage system being clogged. The provided solution was to run air through the water drainage pipes, which my husband did. However, the vehicle still had some water appearing behind the driver's side seat during the lighter rainfalls afterwards. As well, the odor that smelled like cigarette smoke had now been replaced with a strong mildew/mold smell. This poses two major safety issues - water going into fuse boxes (water & electrical don't mix), as well as the mold/mildew being inhaled - especially of concern since we have two toddlers sitting in the backseat of this family vehicle. One dealership was unable to duplicate water inside the vehicle, but found the water drain pipes partially clogged. Other dealership noted mold/mildew smell and did an ozone detailing.
