2018 Chevrolet Equinox

The contact owns a 2018 Chevrolet Equinox. The contact stated that while her daughter was driving at 30 MPH with the contact seated in the front passenger seat, the contact attempted to open the retractable sunroof shade cover, which retracted only 6 inches. After several attempts, an abnormal loud sound was heard, and the shade cover detached, hanging down and obstructing rear-view visibility. The manufacturer General Motors was notified of the failure via telephone and referred the contact to a dealer and to the NHTSA Hotline for assistance. The failure mileage was 30,115.

start-stop accumulator is leaking fluid on transmission. Fluid coming from bolts and gasket area.

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.

I am an investigator w/ the Medical Examiner's office in Dallas, TX. We are investigating the death of an individual who was inside a 2018 Chevy Equinox that was "rebuilt." During the minor accident, the steering wheel airbag deployed, but exploded and shot many large pieces of debris and shrapnel at the decedent's face. Ultimately leading to her passing. After the examination, a large piece of metal w/ a serial number was located. [XXX]. We are working alongside Dallas PD VHU for this crash.

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.

The car had a engine code of P171d my safety and others was put at risk because of the vehicle malfunction while not able to drive after the light turn green or keeping maintaining a searching speed. The engine code was confirm at the dealership while getting serviced. The engine light up here, two days before going to the dealership to get it serviced.

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.

While turning right at a red light my vehicle started making knocking noises, loss of acceleration then the ECM (limp mode) and ESC code happened. Protecting the vehicle from damage due to transmission fluid loss. Looked under the car and Transmission fluid was pouring out between the transmission and drive shaft. Car will no longer start due to codes being present from the computer shutting the car down during fluid loss.
