Recall number n202313440 my car matches make, model, and year but for some reason is not included in the recall and my vehicle has the leaking bolts. Please review.
Multiple occasions of “engine reduced power” and vehicle stalling/jolting/jerking when trying to go over 45 mph. When trying to go to work Monday - on the interstate, it was jerking/jolting when trying to increase any speed and brakes were getting harder to press on, decided to try to reduce speed and get pulled over without the brakes, car was overheating completely. Now seeing multiple people have had this issue with the same car - I’m not sure whether it’s comforting that I’m not the only one or terrifying to know there’s multiple vehicles on the road experiencing this dangerous issue. Seeing a pending lawsuit did not surprise me one bit - I am not happy whatsoever about risking my own life and others on the roadway due to this not being a priority in the first place to correct before selling this vehicle to me, buying it with my hard earned money. Greedy greedy.
I was driving to work, when I got off the exit I stopped at sheetz. When I got back in the car my brake pedal was stiff as a rock, and there was oil on the ground. A friend of mine does mechanic work so I called him and he said it sounds like the vacuum pump. I had the car towed to his garage, the tow costed me $400 which was very cheap considering where I was located. When I got it to the garage he confirmed that it was the vacuum pump and we removed several pieces of metal from inside the engine. I now have my car at the chevy dealership in chippewa PA. They told me to be $180 a diagnose it, well they just called me a little bit ago and said it's going to be another $900 to take everything apart and to truly diagnose it. I'm finding out now that gm has known about the failing vacuum pumps and they kept producing them anyways. I see there's a class action lawsuit taking place, and I am not very happy. My life was put at risk. And now I'm expected to be stuck paying this huge bill?.
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. I am submitting this report in case similar incidents have occurred and to support an potential investigation int vehicle safety. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
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.
While driving, my engine light came on. After taking it in, it turned out that I had water/oil freezing in the intercooler. This could have been very dangerous when I was driving. I have had the gm wrap put on it. I am hoping that this will not be a problem again.
Turbo/superchargers malfunctioned, and I had to have it replaced back up sensors do not work properly. Say backup, assistant, malfunction.
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 $1,600—is not covered under our extended warranty, as the shield was not installed on the vehicle at the time of purchase. The vehicle remains unsafe to drive. When accelerating, engine rpms surge from approximately 2,500 to 4,000 rpm, and the vehicle can suddenly decelerate, creating a serious risk of rear-end collisions if a following driver is forced to brake abruptly. This issue represents a significant safety hazard. Chevrolet has acknowledged the defect by creating a corrective part, yet is declining to cover the repair cost, leaving the responsibility with the customer for a known design issue. Please let me know my next step.
I bought the Equinox with 30,000 miles on it. It's at 67,000 now and I maintain the vehicle regularly. So why have I replaced the throttle body already because it gets dirty fast? and now I'm getting a check engine light for p2099 turbocharger underboost. When the vehicle is not old it's 5 years old, hasn't been driven hard. So why are you using a crap 1. 5l engine with a turbo that is notorious for these issues??? and what's worse the engineering is horse s$*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.
My engine started running rough and, as a result of a repeating po301 code, the car was towed to lester glenn of toms river. Their diagnostic scan report (codes dtc po301 & dtc po303) found the engine assembly has scored cylinder walls due to failed piston rings. The entire engine had to be replaced. The odometer reading was 19,000 miles. Piston rings are designed to last 150,000 plus miles. For them to be worn enough to score a cylinder wall at 19,000 miles is a textbook definition of a manufacturing defect. Piston failure represents a serious safety defect as it could have caused a total loss of power at highway speeds. This was a safety-related manufacturing flaw, and not a maintenance issue. Gm refused to pay for the repair bill in full.
December 2025 I was at a complete stop and the car clunked and the brake pedal got hard hard to push and then a couple months later a brake sensor light came on and when I plugged the code reader into it, it said give me a brake sensor code, and then it started slamming on the brakes all by itself when I went to takeoff hard like give you whiplash hard and it didn’t just do it once it did it a few times and then it wouldn’t go into reverse and then it wouldn’t go in neutral, and then it started smoking. My safety was affected by it, slamming on the brakes that could make someone hit me. It could hurt my back and neck. Yes, I have proof. Yes, I notified the dealer. Yes the vehicle has been inspected and I got an estimate by two different car lot the one I bought it from ken valor motors, and matt mazzoni’s I have. Plus I have diagnose diagnostics printouts from onstar and this is a 2020 vehicle. It should not be having these problems and now I’m stuck paying for a vehicle that I can’t even drive. !!.

Engine burning excess oil causing engine to go in safety mode and preventing car to go over 25 miles per hr. This happen on a major highway with two kids in the car and was almost rear ended. Took to dealership who has recieved bulletins regarding this issue and will repair the engine. To me this should be on a recall due to saftety.
I was driving the car and suddenly the car started accelerating on it's own. No cruise control was on . My wife was in the passenger seat and it was lucky as I did not panic , just taped on the brakes to slow down. This happened many times until we got home and it is dangerous and scary, also this is a know problem with this model car. No lights or warnings came on. We could have easily crashed into a vehicle in front of us, run a red light , etc. No inspections by anyone, maybe it was inspected by the dealer?.
The vaccum pump seized which is connected to the camshaft which broke causing the timing chain to break. This caused the vehicle to lose breaking g power and almost wreck.
Engine loss of power while on highway. When tried to excelerate engine sputtered, going up small incline it would not exceed 50mph. Took to auto shop and spark plug tip was broke and error for cylinder #1. They said take to dealer. Took to dealer and they said engine failed. Cyclinder #1 no combustion. Vehicle had 87,000 miles. Engine had to be replaced. $13,000. Gm assist covered some but I paid $9072 to replace engine. Vehicle at approx 25000 miles had same issue. I took to dealer and they said a spark plug was cracked and had to replace. I took my vehicle in every 7k miles for oil change and inspection to local conrad’s total car care. I was originally quoted verbally $9900 for engine repair. I called gm to file a complaint and they said engine “gm cost assist” program called me. When they got involved they offered $4100 towards repairs and dealer - serpentini westlake, OH increased their quote to $13k so I still pair $9072. Dealer got an extra $3k for me calling gm to complain and I “saved” or got $800 benefit from gm cost assist. What a scam. Dealer refused to give me paperwork showing the details of repairs or breakdown of cost. I received a receipt that stated engine replacement $9072. They wanted me to sign the receipt but would not let me read or view any of the attached paperwork. I refused to sign the receipt and they reminded how much of a favor they did for me by giving me a loaner for approx 10 days while replacing my engine. They additionally said they aren’t required to provide me with any details regarding the gm cost assist or pricing.

I put the vehicle into reverse to back in into my garage when it suddenly lurched forward and hit the garage door on the garage across the alley. There was damage to the garage and the car's front end. It has never done anything like this before.
Engine light continues to turn on after taking it to shop multiple times and no one can find the problem. Code shows p0299. Everything has been checked and there’s nothing to correspond with this code. This has been going on for a year now with multiple fees paid to diagnose and repair.
I have 149,000 miles in this car. In my lifetime of being the one owner and purchasing this car brand new the vacuum pump has failed five times. Twice now resulting in blown engines. And still no recalls.
