2019 Chevrolet Equinox electrical problems

Filed Oct 24, 2026 · Brakes, Electrical · CA

My 2019 Chevrolet Equinox has experienced repeated engine and transmission problems despite multiple repair attempts. I spent approximately $10,000 on a new transmission, but the vehicle still runs but will not move. These recurring failures raise serious safety concerns. The exact cause is UNKNOWN, and repair records may be available for inspection.

SAFETY VEHICLE COMPLAINT / DEFECT REPORT Vehicle: 2019 Chevrolet Equinox Complaint Type: Brake Failure / Loss of Braking Ability / Vehicle Malfunction Incident Date: XXX Location: [XXX] Request: Safety defect investigation Description of Incident On XXX, while my 2019 Chevrolet Equinox was being operated in the [XXX] area after exiting the highway, the vehicle experienced a serious and potentially life-threatening malfunction. As the vehicle approached a situation requiring the driver to stop, the brake pedal was pressed, but the vehicle did not stop as expected. The brake pedal went completely to the floor, and there was little to no braking response from the vehicle. At the same time, the vehicle experienced additional significant mechanical/electrical problems. The vehicle would not properly shift into gear, and the vehicle began flickering/shaking and malfunctioning. The combination of loss of braking ability and the inability to properly shift the vehicle created an extremely dangerous situation. A failure of the braking system while the vehicle is being operated on or near a highway presents a serious risk of a crash, injury, or death. The vehicle was subsequently inspected by a mechanic. I was informed that the issue was possibly related to the fuel pump, although the cause of the brake failure and the other vehicle malfunctions has not been definitively established. I am requesting that this incident be formally documented and investigated as a potential safety defect involving the 2019 Chevrolet Equinox. My primary concern is that the vehicle experienced a complete or near-complete loss of braking ability, with the brake pedal going to the floor and the vehicle failing to stop normally. The simultaneous inability to shift gears and additional vehicle malfunction makes this particularly concerning. I believe this issue warrants investigation to determine whether there is a recurring defect . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On multiple occasions my vehicle (2019 equinox LT) that I bought just over 30 days ago has falsely activated the forward collision feature and slammed on its own brakes followed by “service ESC” and “service brake assist” with traction control lights and stability control lights illuminating. Dealership has confirmed that 4 computer modules are out of date on programming/updates. This is a critical safety issue and I am unsure why it hasn’t been recalled as I have read multiple instances of this. Unfortunately because it has not it is a hefty repair bill. When this happened the last time before heading into the dealership, there was a vehicle behind me that could’ve rammed into my rear due to the sudden and excessive braking at highway speeds when I was pressing on the gas.

The instrument cluster and driver information center is completely blank, and none of the steering wheel controls are operating. Vehicle starts and runs normally, but no indication of speed, turn signals, headlights, gas level, etc.

In FMVSS 138, it says that the tire pressure monitoring system will warn drivers of under inflated tires. My TPMS system failed on my MY19 Chevrolet Equinox around 49,000 miles and no longer warns me of underinflated tires for all four tires. To fix it I would have to pay out of pocket costs starting at $732, per the dealership, on a safety critical system that should not fail at 6 years/49,000 miles. There is no recall issued after a check of my VIN. Since 1974, the OEM has had a responsibility to provide a free remedy for safety defects and noncompliance. In 2015, the free remedy was changed from 10 years to 15 years by the FAST Act.

Vehicle experienced derating. Check engine light on. Called mobile repair service. 20 year mechanic. Replaced Pedal Sensor. Fail. Second visit replaced Throttle Body. Fail. He advised better to take it to a reputable shop. Did. Shop worked on it for 2 months and ended up replacing ECM. I finally had the unit towed to an Electrical Specialist in Longmont Colorado. They replaced Wiring loom between pedal sensor and car worked again. Drove car to Kansas and after about 300 miles, loud boom and messages on display. ECM engaged electric emergency brake hard at 79 MPH. WAS on cruise. At 20 mph car stopped messaging, and resumed normal operation. Pulled over, checked car. 50 miles from nearest city. cautiously drove about 20mph, then 30, then more until up to speed limit again. Worked fine 140 miles (needed a population center to get car fixed)) and it happened again. Limped car a few miles to repair in Salina, Kansas. ECM erased all miles, messages, etc. They could find nothing. my research showed the 2025 Equinox EV recall (We had replaced ECM and reprogrammed). I went to get car and risked driving, but without cruise. Warnings would come up, but car ran. No more emergency stops, but plenty of warnings. $3K in repairs and still problem. I believe current problem is electrical that Equinox is known for. The ECM/Reprogramming problem that activated the Brake is the issue here and previously reported by many. Extremely dangerous! Car has 50K miles. Was flawless driver until now. Note: Unit was Rebuilt Salvage. I bought at 1460 miles. Hit right rear, Replaced right rear sheet metal, Rear driveline on right side (Genuine GM parts), Replaced Hatch door. Inspected by state of Michigan. Reputable Rebuilder. Zero bad reviews. Hundreds of excellent reviews. P.S. Cannot take to Chevrolet - they universally refuse to work on car - not to even change oil.

I was driving one day and my radio shut off, screen black and no sound. Came back on like it rebooted. Worked fine. The next day it did the same thing but only the screen went out but for longer this time. I work at a collision center and used our scanner to see what the problem might have been. It was giving a bunch of codes for radio and onstar. The next day it was perfectly fine. So I scanned it again just to see if the codes were still there. They weren't, but instead had 2 codes for brake control module in my engine and my transmission. My fan in the front has also been making slowing down and speeding up randomly.

To Whom It May Concern, I'm writing to formally report a critical failure of the Auto Start-Stop system in my 2019 Chevy Equinox that occurred today, resulting in a hazardous situation during rush hour traffic. While stopped in the northbound left turn lane of Route 202 at the intersection with Baltimore Pike, the vehicle’s Auto Start-Stop feature engaged as expected. However, upon releasing the brake to proceed, the engine failed to restart, and the vehicle remained completely inoperative — engine off, no power, and unresponsive to ignition attempts. This failure caused the vehicle to become stranded in a live intersection during heavy traffic, posing a serious safety risk not only to myself but also to other motorists. A Pennsylvania State Police officer arrived on the scene and assisted by pushing the vehicle across three active lanes of traffic while in neutral, performing a battery jump with a brand new battery of five months, and escorting me home to ensure I was safe. This situation was both dangerous and unacceptable, especially considering that the failure stemmed from a system designed for emissions/fuel efficiency, not safety. The Auto Start-Stop feature in this vehicle clearly introduces critical failure points without adequate redundancy or reliability, particularly in real-world driving conditions. Additionally, I contacted my local Chevrolet dealership and spoke directly with a technician in the service department. He confirmed that they have had multiple customers reporting similar failures with the Auto Start-Stop system. According to him, this is not an isolated incident, and in several cases, it has placed drivers in equal danger. I am formally requesting: An investigation into this incident, Information on any existing Technical Service Bulletins (TSBs) or recalls related to this failure, A full inspection of the vehicle at GM’s expense, And a report on what steps GM is taking to prevent similar failures from putting other drivers in harm’s way.

Started off with my computer on my dashboard randomly turning off I called the dealership they told me it was because I was not using an iPhone Apple chord. Another instance I was driving down the road close to home and my car started stalling and flashing engine codes on my dashboard, I managed to make it home and park. The next day I tried to start my vehicle and it sounded like the battery was dead. I called a tow truck. The car had enough power for me to put it into neutral and get it onto the flatbed. My mechanic is less than 10 minutes away by the time they got it there they couldn’t do anything to move the vehicle. It had to be jacked up on the flatbed and rolled off because the car would not do anything My mechanic spent two weeks going through the computer system only to find out that I needed a software update and that my computer software had major glitches and electrical issues. Sometimes when I get into my vehicle to start it, it won’t start. I’ve learned that I need to put both feet on the brake. Push it all the way to the floor wait a second and then it will start otherwise my break seizes up and I’m locked out of my vehicle for at least an hour. This has happened to me on the side of highways in public parking lots in front of my home at the grocery stor. This past week I’ve had to get my car jumped 2 different times because when I turn my car off and lock it, my brake lights do not turn off and it killed my battery. I’ve had nothing but issues with the computer since day one from what I’ve googled this is a known issue with my make and model of vehicle. I contacted the dealership and they want to charge me thousands of dollars for something that was a factory defect.

I was driving down the road and my engine stopped. It stopped so suddenly that I did not have time to get out of the road and my safety was put at risk. When I took it to a certified Chevrolet dealership, they told me that the vacuum pump failure caused extensive damage to the motor and I needed to have my entire motor replaced. When I asked them what I could have done to prevent such catastrophic failure, they stated that there was nothing to prevent it. I did not have any warning on my dash at the time of the incident. This was at least the 2nd vacuum pump failure on this vehicle since I've owned it. I got it replaced at a certified Chevrolet dealership in 05/2022 when my brakes went out. In 05/22, the brakes went out but I was in a driveway and I did not feel my safety was a concern at that time. Now it's not even been 3 years and the vacuum pump failure risked my safety and caused catastrophic damage to engine to be replaced.
