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.

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).

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.

Case number 11715650 , check engine light went on , and the vehicle reduced speed, I took car into dealership, they said the engine had an ice problem and a repair would be needed, they said that this was a flaw in design, and it should be part of a recall, and that this is a common problem with this vehicle. The cost of a repair would be around $1000. 00 . T fill this should be covered by the manufacture because of a design flaw.

Got word from the mechanic at the dealership that the cam shaft is leaking oil as well as the fuel injectors retainers are out and need to be sealed as they are also leaking. The engine went into safe mode to prevent any engine fires.

Vehicle is leaking coolant excessively. Faulty 55513550 water pump (acdelco/gm oe) commonly causes engine overheating, coolant leaks (often from the weep hole), and unusual noise (squeaking/rumbling) in 1. 6l diesel engines for Chevrolet cruze, Equinox, and GMC terrain. It may cause cabin heating issues and trigger engine codes. Major problem #2: electrical described by tony dubois at midas (cinco ranch location) - electrical pulse are being received through the wiring causing lights to go on and off. No other manufacturer or repair shop can fix this issue because of the inability to access the coding. This is an dealership software issue.

Transfer case and front differential failure. No warning lights came on beforehand.

The check engine light came on and the engine lowered performance because the intercooler froze and cracked. Despite there being a service update to stop that from happening, we were never informed of the update from chevy, only once it had happened did they tell us about the update and included it in the repair cost.

Due to cold temperatures, the main rear seal blew causing engine, coolant and intake systems to fail. Full replacements are now needed.

I would like to formally file a safety complaint regarding my Chevrolet vehicle and to express concern over Chevrolet’s handling of a known defect. On January 22, while driving to work in cold weather conditions, my vehicle experienced a sudden and dangerous malfunction. The engine unexpectedly revved to approximately 4,500 rpm, the check engine light illuminated, and the dashboard displayed an “engine power reduced” message. Despite removing my foot from the accelerator, the vehicle did not slow down as expected. I was able to pull over to the side of the road and bring the vehicle to a stop. I immediately contacted my local Chevrolet service department and was advised to bring the vehicle in six days later, the following Friday. Due to the safety risk, we did not use the vehicle during this time out of concern for a potential accident. When the vehicle was inspected by the Chevrolet dealership, we were informed that Chevrolet had identified this issue as being related to cold weather operation and that a custom shield had been designed to address the problem. We were also told that Chevrolet vehicles were not adequately designed for cold weather conditions, which led to this failure. Despite this acknowledgment and the fact that Chevrolet has engineered a corrective part, we were informed that the repair—costing approximately $1,600—is not covered under our extended warranty, as the shield was not installed on the vehicle at the time of purchase. The vehicle remains unsafe to drive. When accelerating, engine rpms surge from approximately 2,500 to 4,000 rpm, and the vehicle can suddenly decelerate, creating a serious risk of rear-end collisions if a following driver is forced to brake abruptly. This issue represents a significant safety hazard. Chevrolet has acknowledged the defect by creating a corrective part, yet is declining to cover the repair cost, leaving the responsibility with the customer for a known design issue. Please let me know my next step.

The manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was unknown.

I bought the Equinox with 30,000 miles on it. It's at 67,000 now and I maintain the vehicle regularly. So why have I replaced the throttle body already because it gets dirty fast? and now I'm getting a check engine light for p2099 turbocharger underboost. When the vehicle is not old it's 5 years old, hasn't been driven hard. So why are you using a crap 1. 5l engine with a turbo that is notorious for these issues??? and what's worse the engineering is horse s$*t, because the air inlet hose is only one time use. But the part is underneath it where you can't reach. Why has this not been recalled yet????????? it's not but a scam to make you take it to a dealership. I'll continue to write complaints this is not right. And I'll never buy one again.

Engine stalled possibly due to a faulty fuel pump. I was able to drive the vehicle without issue until I pulled up to my house, when the engine stalled. No warning signs prior to the incident. Proceeded to put the vehicle in park and start the engine again. The engine had trouble starting again, sputtering even when the gas pedal was pressed (no response to the gas pedal). No sound comes from the fuel pump when trying to start. Battery in good condition. Lucky vehicle did not stall while driving down the road at 60 mph. Vehicle will have to be towed to a mechanic.

I have had this car for a little under a year. In January of this year 2026, I was driving on the freeway when I received a. Reduce engine power alert. Which caused me to immediately get off of the freeway put the car power down before I can make it another half a mile. After having it looked at several times what was thought to be a rear seal oil leak turned out to be a leak in the transmission. Repairs as of now our thoughts to be needing an entire new transmission. . Repairs as of now our thoughts to be needing a entire new transmission. I don’t understand why there is no recall for this specific situation. Upon my research, I have seen many complaints many concerns of the exact same thing of the exact same making model of these cars. I have not been able to drive the car since January and have been paying for a rental. With cost estimated to be between 1500 and $4000. Surely there’s something that Chevrolet can do for all of the people who are having the same problems with the Equinox.

There is water my oil and I have a blown head gasket. I get all maintenance done and have oil changes on time.

I am submitting this complaint regarding a serious safety defect involving a 2017 Chevrolet Equinox that experienced a sudden and complete loss of engine power while the vehicle was in motion. While traveling approximately 50 mph in active traffic, the engine abruptly shut off and the vehicle immediately lost all ability to accelerate. The loss of propulsion was total and occurred without warning. There were no warning lights, alerts, or indicators of a low oil or engine condition prior to the failure. Moments before the shutdown, the engine began making an abnormal mechanical noise. A video was recorded during the incident while the vehicle was still operating in traffic. The recording captures the engine failure in real time, including the vehicle decelerating from approximately 50 mph to a complete stop as the engine shut down. I was able to coast into a breakdown lane and then into a nearby parking lot, narrowly avoiding a collision. A sudden loss of propulsion at this speed and in these conditions presents a severe and immediate safety risk to vehicle occupants and surrounding traffic. This vehicle has been regularly serviced by authorized Chevrolet dealerships and maintained according to the manufacturer’s recommended schedule. At no point was I advised that the vehicle required frequent manual oil checks between scheduled oil changes, nor did the vehicle provide any warning prior to engine shutdown. I routinely operate this vehicle at highway speeds and regularly transport my child. Had this failure occurred on a highway or in heavier traffic, the risk of serious injury or fatality would have been significant. The exact cause is unknown at this time. The vehicle is available for inspection, and I can provide maintenance records and video documentation upon request.

I am on 20 service calls. Mine is currently having onstar issues screens glitching, apple carplay won’t connect, sensors on mirrors are going off nothing beside me, when I hit my breaks it keeps turning my emergency brake on and engine power reduced keeps coming on dash but the dealership is saying gm said my warranty is voided due to a aftermarket part.

My car has a slow crank and when I am driving down the road it cuts off completely and does not want to crank. I have a signal on my car that says reduced speed and the speed is cut down and drags . My car also smells like gas and there is a leak coming from the vehicle it drains really bad . My brakes goes out every few months . My car radio goes out like there is a shortage. Its horrible.

The 2. 4 liter engine in my car has had excessive oil consumption. Now the engine oil is like peanut butter and the blow by out the oil fill is strong.
