Engine And Engine Cooling Problems of Chevrolet Equinox - part 2

I bought the 2020 Equinox may the 9th 2026 the dealership concealed a lot of things going on this vehicle and I complain to them two days after purchase he told me I was stuck with it in the meanwhile as I drive the vehicle I have had repairs done but it's something going on with the acceleration it accelerates on its own sometimes and slow to pick up speed. The steering seems to get away from me at times that makes me feel like I'm going to lose control when driving. I have almost had a couple of accidents since then so what really worries me is the steering problems which I just had a little alignment done today July 15th 2026 and the accelerating from time to time went backing up or pulling off. I do feel like the safety of others can be at risk for should I say my safety is that risk at times so I am extremely cautious when I'm driving. No I have not had really anyone to look at I have been having a car looked at for many issues but that issue I am still trying to get in to see a mechanic that I'm used to dealing with but he's been backed up. No there are no lights of any such but when I purchased it the sensors in the tires and I've had that replaced and I've noticed this situation with the acceleration when I bought the vehicle and the slow speed pick up when driving.

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).

I was trying to stop at a light and the brakes wouldn't work. I almost crashed into the car in front of me but I had to step on it really hard to stop. Then the brakes were stiff and it was hard to stop. I brought it to a chevy dealer yesterday and they said the vacuum pump exploded and pieces were in the engine, and it messed up the cam shaft. This is 5l worth of damage. When I looked it up online it seems this has been an issue with gm cars and the Equinox was left out of the recall which could have prevented this. I have 95k miles on this car and never had an issue until now. However it is not worth spending 5k on a car that is high in mileage.

I am reporting a vehicle fire involving a 2020 Chevrolet Equinox [xxx] ). The fire originated in the engine compartment. The official fire report lists the causes as "undetermined", with the area of origin identified under the hood. There were no prior warning lights, mechanical issues, or indications that a fire risk was present. The vehicle was being used under normal conditions and was properly maintained to my knowledge. The vehicle was declared a total loss by my insurance company. Due to the undetermined cause and engine compartment origin, I am concerned there may have been a potential mechanical or electrical defect that was not identified.

On Saturday, April 18, 2026, I was driving home from a neurology appointment with my two daughters, including my child with special needs. I intentionally chose not to take the expressway and instead drove a lower-speed route home for safety reasons. While traveling approximately 35 mph, the vehicle suddenly displayed an “engine power is reduced” warning. As I attempted to safely maneuver through traffic and pull over, the brake pedal became extremely stiff and difficult to depress, requiring significant physical force to slow and stop the vehicle. The sudden reduction in braking assist created a serious safety hazard for my family. Had this occurred at highway speeds on the expressway, the outcome could have been catastrophic. A post-incident inspection identified failure of the vacuum pump drive assembly and related timing/variable valve timing (vvt) components. Photographs taken during disassembly document the condition of the timing chain, camshaft, vvt actuator/phaser, vacuum pump assembly, and associated components at the time of repair. Diagnostic records also documented dtc code p1101 following the incident. The vehicle is currently undergoing further inspection and diagnostic evaluation at a certified Chevrolet dealership to validate cpo warranty coverage and determine the full extent and cause of the failure. Based on the sudden loss of engine performance and reduction in brake assist, I believe this condition represents a significant safety risk to vehicle occupants and the public.

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. Continued dripping intermittently for hours. Safety risk: complete vision obstruction while driving at highway speeds. 3. Intermittent safety chimes (electrical/infotainment): - ongoing for weeks: five rapid electronic dings with no dashboard warning lights or indicators. Occurs sporadically while driving (10 occurrences in one recent day). Dealer previously informed by phone but no resolution. Safety risk: distracting chimes with no identifiable warning create driver confusion. 4. Additional electrical: remote start now works intermittently. All components available for NHTSA/manufacturer inspection. Dealer confirmed March 17 battery inspection but found no cause. No manufacturer inspection. No warning lamps preceded any failures except unexplained chimes. Problems began immediately after certified pre-owned purchase despite carbravo certification. Safety defects render vehicle unreliable and hazardous.

I was driving in GA and my low engine power light came on and I lost complete ability to brake. The brake pedal was hard and would not go down. I towed my car to jim ellis Chevrolet in atlanta. They called a few days later and told me I needed extensive engine repairs that would cost over $5,000 but gm would take care of some of it. I paid $1980. 00. I went to pick up my car and was nervous because I lost brakes on a highway and was afraid. I asked them if they were sure everything was repaired and I would be safe and they told me it was tested extensively and driven and all was good. I drove around 2 hours after leaving and my engine light came on and my brakes failed again going 70 miles an hour surrounded by semis. I called jim ellis and they told me to tow it to walter jackson who told me it was a vacuum pump that they would have had to remove during the repairs. In addition there is a class action against gm about these pumps for my year and make of car. I have asked for a refund from jim ellis contacting ownership, gm, service team and no one will respond to my calls or emails. I filed a customer complaint with gm and they are accepting zero responsibility as well. I paid thousands of dollars between both repairs and rental cars and the least I would like for them putting my life and others around me at risk on a freeway is my money back.

The engine failed while driving on the highway on two separate occasions due a fuel pump issue. The first time it happened, it was just reduced power (could only drive maybe 40 miles an hour). I brought it to the dealership and they said that general motors told them it needs a software update which they completed. However the second time it happened (4 months later) it was full engine shutdown in the left lane on a 65mph highway with my family (including my toddler) in the car. The first time it happened we were able to make it home by driving with the hazard lights on very slowly. But the second time we were doing the 65 mph speed limit in the left lane on a 3 lane highway. To avoid causing a pile up of cars or a deadly accident, we had to use the momentum of the speed we were going to try to safely drift across three lanes of congested traffic just to make it safely to the shoulder. We were then stuck on the side of the highway in the sun on an 80 degree day with a car with no power. I had to remove my two year old from the car so he didn't get heat exhaustion and stand on the side of the highway holding him in the little bit of shade we could find. The car then had to be towed back to my dealership over an hour away because it would not even turn on. The dealership was not able to replicate the issue the first time it happened, but did the software update that the manufacturer recommended. To my knowledge its only been inspected by the dealership. The only warning signs/messages/lights were the ones happening as the engine was failing/shutting down. There was no advanced warning. This care is less than two years old and its a leased vehicle from the dealership down repairs, I work from home there are less than 20k miles on I, this is not neglect on my part or over usage in anyway of the vehicle.

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.

Vehicle looses power and can very easily cause a bad wreck I've replaced multiple thing and it still does it I'm not sure what it is possibly the timing or something to do with camshaft.

Car uses excessive amount of oil! we have had the timing replaced and now it’s stating the p0420 catalyst system efficiency below threshold bank 1.

Brake system has failed. “brake assist service” has popped up on screen. Taken to two separate facilities who said this is a known problem with this vehicle make and model.

My granddaughter was driving the vehicle and experienced a catastrophic engine failure while driving down the road. Warning messages and audible sounds began and said to turn off the vehicle immediately. The brakes completely stopped working at that point. She pulled over immediately and called to ask what she should do. She was approximately 1/2 mile from home and she drove approximately 10mph to her driveway, pumping the brakes helped get the vehicle to her driveway. The vehicle was then towed to the dealership.

Recall/loss of power I am filing a safety complaint regarding a 2023 chevy Equinox. The vehicle began losing engine power and will not go over 40 mph. This creates a dangerous driving situation because the vehicle cannot maintain highway speed. The vehicle has a fuel system recall, and the issue appears to be related to the fuel system. The vehicle is currently at a Chevrolet dealership and has been there for almost a month. The vehicle is currently inoperable. This is a safety concern because loss of engine power while driving could cause an accident. I am requesting that this issue be investigated as a safety defect. Sincerely, [xxx]   VIN [xxx] mileage: 63,000 information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Engine went into limp mode with now warning. I recieved a reduced engine power warning and the vehicle lost acceleration on the highway almost leading to an accident. I had the car towed to coggin gm for diagnostic and was told that my throttle body has to be replaced. I was advised that this is common issue with this engine and notify due to a recall of older Equinoxes.

The abs braking and stability control light came on and has stayed on and took to mechanic shop and was told to repair would be $4000 . That's more than what the car is worth!changed motor oil many times since I owned the car and it uses oil quite much. Ihe oil gauge can say I have 70 percent oil and the dipstick reads no oil so I must put 2 -3 quarts of oil in car because I can hear lifters rattle due to lack of oil. The abs stability control keeps car steady especially in I snow or rain weather and can lose control of the 2012 chevy Equinox. If I was to drive vehicle on long trip the motor could freeze up while driving and shut down and cause dangerous situation in traffic.

Vehicle safety complaint – 2024 Chevrolet Equinox I am reporting a safety defect involving unintended vehicle movement and improper shutdown behavior. While operating my 2024 Chevrolet Equinox, I was able to shut the vehicle off even though it was not in park. After shutdown, the vehicle rolled forward on its own and struck a tree. At the time of the incident, the radio remained on despite the vehicle being turned off, indicating the vehicle may not have fully entered ignition-off state. This incident suggests a potential malfunction involving one or more of the following systems: gear position detection system transmission park engagement mechanism electronic shift control module ignition state logic or body control module the vehicle should not allow shutdown unless it is in park, or it should provide clear warnings and prevent unintended movement. This behavior presents a serious safety risk of rollaway incidents. I am requesting a full diagnostic inspection and documentation of all stored fault codes, including history codes, prior to any resets. Please also check for software updates, technical service bulletins, or known defects related to shift position recognition or ignition state control. This issue resulted in unintended movement and property damage and poses a significant safety hazard.

Started with a broken key, the security system passlock lll+ left me stranded in winter. I got it working temporarily after finding the other part of the key. Put it in ignition and then the other half to get it started but didn't always start. Apparently this is common on chevy vehicles.
