2018 Chevrolet Equinox Owner Complaints

Complete and sudden failure of Transmission involving the clutches (clutches are burned up inside the transmission). No warning or dash lights. Confirmed by mechanic and the solution is transmission replacement ($10,000). Car would not accelerate and began losing power on highway. After I exited the highway, the car would not engage gears and stopped accelerating resulting in having to push it out of the roadway and get it towed to my mechanic for diagnostic.

Chevrolet 2018 Equinox with 2.0L has a fail for no OBD communication. The vehicle was take to two separate Smog Local State Inspections; however, the vehicle failed to communicate with the system. I believe from looking at previous complaints on NHTSA that the vehicle has a module with defects and needs to be replaced. Vehicle has 49,000 miles. Previous complaint states that the local dealer was contacted; however, Product Emission Recall: N202298780; repair was available. The manufacturer was made aware of the failure.

My 2018 Chevrolet Equinox 1.5L developed an active gasoline leak. After the vehicle is cranked/started, gasoline begins leaking from underneath the front/engine area and forms a visible puddle on the ground. Prior to discovering the leak, the vehicle had intermittent hard-starting symptoms where the engine would crank/stutter several times before starting, along with a strong gasoline odor. The exact failed component has not yet been confirmed by a dealer or repair facility. I stopped driving the vehicle because leaking gasoline near the engine/electrical components creates a serious fire and safety risk. The vehicle is available for inspection. Chevrolet advised me that there are currently no open recalls or programs associated with my VIN. I am reporting this condition to NHTSA because of the severity of the fuel leak and potential fire hazard.

On approximately 09/04/2026, while driving my vehicle and slowing to a stop, I applied the brake pedal and it suddenly became extremely hard to depress. At approximately the same time, the steering became very stiff and difficult to turn. I believed I had lost normal braking ability and had difficulty controlling the vehicle while attempting to stop. The engine then shut off on its own. After the vehicle stopped, attempts to restart it were unsuccessful. The engine would crank/attempt to start but would not complete the ignition cycle and remain running. A ticking noise was also present. The vehicle remains available for inspection and is being towed to a local GM dealership for diagnosis. The specific component responsible for the failure is currently UNKNOWN. The vehicle previously generated diagnostic code P050F in January 2026. Following the 09/04/2026 failure, diagnostic code P0017 was identified. I did not receive P0017 prior to this incident. I did not observe an overheating warning or temperature-gauge indication showing that the engine was overheating before the vehicle shut down. The incident created a safety risk because the brake pedal became extremely hard to depress and the steering became difficult to operate while the vehicle was in motion, significantly affecting my ability to slow and control the vehicle. There was no collision or injury. As of the date of this complaint, the cause has not yet been confirmed by a dealer, independent service center, manufacturer, police, or insurance representative. The vehicle is being taken to a GM dealership for diagnostic inspection. I can provide the vehicle and subsequent diagnostic/repair documentation for inspection upon request.

In my chevy equinox 2018 my vacuum pump and brake booster failed when I was driving and I could not brake. I slid into the gravel side of the road on the 138, luckily there were not alot of traffic at the time cause I would have caused a major accident. Never had any braking issue till now. Now this is a major financial hardship on me to fix this issue that should have not happened if it got recalled to fix this issue on this certain model. No lights, no indicator lights or anything came on either which was scary. And I have no problems or any other issues with the equinox. It just failed all of a sudden.

While I was getting off the freeway, my vehicle displayed the “Service Brake Assist” warning. When I attempted to brake, the brake pedal became extremely hard and would not respond normally. The vehicle would not stop normally when I pressed the brake pedal. I was almost involved in a crash because I could not brake as expected. I had to use the emergency parking brake to help bring the vehicle to a stop and avoid a collision. Component/system: The exact failed component is UNKNOWN. Based on the “Service Brake Assist” warning and the extremely hard brake pedal, I am concerned there may be a problem with the brake-assist system, vacuum system/vacuum pump, brake booster, or related components. The vehicle is available for inspection upon request. Safety risk: This created a serious safety hazard because I temporarily could not stop the vehicle normally while exiting a freeway. I was almost involved in a crash and had to use the emergency parking brake to help stop the vehicle. Dealer/service confirmation: UNKNOWN at this time. The problem has not yet been confirmed by a dealer or independent repair facility. Manufacturer/police/insurance inspection: UNKNOWN/No inspection has been performed by the manufacturer, police, or insurance representative at this time. Warning/message: The vehicle displayed “Service Brake Assist.” The warning appeared before/during the braking problem. At the same time, the brake pedal became extremely hard and difficult to press normally. I am requesting that NHTSA investigate this incident along with other complaints involving 2018 Chevrolet Equinox vehicles experiencing “Service Brake Assist,” hard brake pedals, loss of brake assistance, and suspected vacuum-pump/brake-assist failures. I am concerned that this may be a safety-related defect that could cause a loss of braking assistance and increase the risk of a crash. I request that NHTSA determine whether further investigation or a safety recall is warranted.

While driving, the vehicle experienced a sudden, catastrophic loss of engine power accompanied by severe engine shaking, reduced acceleration, and a lit Check Engine / ESC light. The vehicle was towed to a technician who diagnosed a complete dead misfire in Cylinder 4. Upon detailed inspection, the ground electrode/tip of the spark plug had broken off inside the combustion chamber while the engine was running. The free-floating metal fragment severely gouged the piston crown and scored the cylinder wall, resulting in a total loss of compression and catastrophic engine failure at just under 51,000 miles. This unexpected engine failure causes an immediate and dangerous loss of motive power while operating in traffic, creating a severe crash hazard for passengers and surrounding motorists. This issue appears to stem from a known component defect (GM Technical Bulletins PIP5657C & 21-NA-255) related to premature spark plug failure and low-speed pre-ignition (LSPI) in the 1.5L turbo engine.

I own a 2018 Chevrolet Equinox. While driving at highway speed, the brake pedal suddenly became completely rigid and could not be depressed. The engine continued running normally, there were no warning lights, and I had to coast into a parking lot because I was unable to brake normally. The vehicle was towed to a Chevrolet dealership. The dealership diagnosed a failed vacuum brake booster and replaced the brake booster at my expense. After the repair, the exact same safety issue occurred again while I was driving at approximately 25 mph. The engine was running normally, there were again no warning lights, and the brake pedal instantly became rock hard and would not depress. The repair did not resolve the condition, and I no longer believe the vehicle is safe to operate. I am reporting this because the same loss of brake assist occurred before and after the dealership’s repair.

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.

On a steep gravel road in a remote area, I pressed the accelerator and the vehicle stopped climbing. I inferred that traction control had intervened, but there was no immediate, obvious indication explaining why the car wasn’t responding. The most frightening part was not knowing what the vehicle was doing. A clear, immediate indication that traction control was actively limiting power would have reduced uncertainty.

The brake vacuum pump has gone out four times now. While driving the brakes suddenly become hard as a rock to push. Of the four times two of them have been close calls to having a serious collision. This is a known issue with these vehicles so it blows my mind there isn't a recall for this.

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.

My 2018 Equinox is failing California Smog due to an incorrect CVN error code, which is covered under Emissions Recall N212345540 or N202298780 and the dealership is refusing to reflash it and asking me to pay for a full diagnostics when there is no check engine light on. I also had a full diagnostic run on June 2nd $289.99 which confirmed this code and referred me to the BAR Referee who also confirmed this is causing the issue.

I was driving and the brake vacuum pump failed and the metal shards went up into the engine. The service light went on as they failed and I lost the ability to brake. Yes, we still have the part and the shards that came out of the engine, but there are still pieces in the engine. my safety was at risk and everyone else's on the road because I had no brakes and was driving 45 mph. The vehicle has not been looked at yet by any professional because so far no mechanic will touch it.

Early this year I traveled to Mobile AL. While I was driving my car made this sound and it lost acceleration but no warning light appeared on my dashboard. My car eventually lost power and I had to get a tow. I went to a repair shop and they explained to me that it was the turbo that’s why I lost acceleration they said a lot of equinox with turbos are having this problem but it only goes out around 100000 mile but I only had 67000+ miles on my car at the time. The mechanic explain it shouldn’t have gone out so soon as it did. Also the vehicle makes a sudden jerk or jolt while driving this maybe an engine or transmission problem without any warning sign signaling there’s a problem with the vehicle. I’ve researched this and learned that this model vehicle has transmission problem while driving

We purchased our car new. Around 70,000 miles or so the brakes went out and were barely usable. We had it towed to Moses in Charleston and it was apparently an issue with brake booster or vacuum pump. I don’t have the specifics at the moment but they fixed it and we drove it home and it did the same thing again with the brakes going out. Had it towed again back to them and they did something else and it was fixed. Fast forward to today and there are 155000 miles in it and it did the same thing. Clearly this is extremely dangerous! Every time it occurred my husband was driving and was able to handle it. If I was driving, it could be a totally different story. Upon a google search it appears there is a lawsuit in Michigan over this because it is clearly a problem and a dangerous one at that. I will also note that my sister in law also has about the same model equinox and hers did it as well.
