2018 Chevrolet Equinox Brakes Problems

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.

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.

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.

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.

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.

Travelling on a highway with 70 MPH posted speed limit, the vehicle dashboard signaled the check engine light and a variety of warnings that "power reduction measure" was enabled and to "service brake assist." At the next available exit, I was able to exit from the highway and go to a gas station, where upon pulling next to a pump the brake pedal became extremely hard and nonresponsive, resulting in poor braking, nearly striking the car in front of me, even at a very low speed. Upon a quick internet search, it appeared that other vehicles were having the same issue, and it was recommended not to drive, as well as information referring to an ongoing class action lawsuit. A tow was called and brought to the nearest Chevrolet service center (Nels Gunderson Chevrolet), where they confirmed the brake booster vacuum pump failed (exploded) and sent shrapnel into the camshaft, noting that both would need to be replaced, which is the exact same repair that other vehicles similar to this one are having or have had.

Driving down a curvey road and my brake pedal was hard without no warning or indication. Almost was hit head on because of this. Looks like the Vacuum Pump Seal failed and I lost all of my engine oil, which caused that to happen.

While going 80mph on the highway at 2:00am on or around 10/6/2023, my power braking system went out without warning. I was able to get it off the road and to a shop where they told me it was the vacuum pump and cam shaft. Repair took a week. 7 months later on 5/31/2024, it went out again, luckily in town going 35mph, and involved the vacuum pump, cam shaft, and this time the oil pump as well. Repair took 5 months due to parts availability. The only time the engine light came on, it was for a sensor unrelated to this issue.

I own a 2018 Chevrolet Equinox with a 1.5L engine. While driving with my children in the vehicle, the car experienced a sudden and frightening failure. The engine began malfunctioning, and after inspection, my mechanic and the repair shop confirmed damage to the vacuum pump, broken engine pieces, and issues with the timing chain and camshaft. These issues are identical to those described in an existing recall for this vehicle, but my VIN is not included. The shop even questioned why my mechanic had to replace the vacuum pump, which shows this failure is directly related to the known recall problem. This situation created a very unsafe condition while my kids were in the car. It is unfair and dangerous that my VIN is excluded when the exact same recall defects are present. I am requesting that my vehicle be included in the recall and that NHTSA investigate this defect further, as it poses a serious safety risk for me, my family, and potentially other drivers.

I was exiting the expressway coming up to the back of a semi truck & the brake became hard to push down. Thankfully I was able to stop in time & didn't rear end the truck. It put me & my [XXX] old in danger had I not been able to apply the force needed to push the brake petal down. No dash alerts appeared until at least 10 min after I noticed the issue. I have a mechanic changing the brake booster. The first part we received was faulty & had to be returned. Currently waiting for another brake booster to come in & attempt another repair.

My 2018 equinox was running perfectly. Then several warning lights popped up on the dash. I pulled into my daughter's school and didn't have power breaks. Even though brake fluid was full. It wouldn't start back up. A mechanic shop looked at the car and said they thought the timing was off. But couldn't guarantee it. Another mechanic looked at it a few days later and said I needed a new power break pump that the had broken at the camshaft connect. He said the car would need to rebuild the motor or buy a used motor because of the damage. I have heard of several people who have had the same exact issue with the chevy 1.5 turbo motor in many chevy vehicles. There should be a recall as there is never a warning that the vacuum break pump is getting ready to go bad and cause severe engine damage.

The contact owns a 2018 Chevrolet Equinox. The contact stated that while driving 70 MPH, the Service Brake Assist warning light illuminated, and the brake pedal became difficult to depress. The contact exited the first available exit and coasted to the side of the road. The vehicle was towed to the dealer, who diagnosed that the vacuum pump had failed and needed to be replaced. The vehicle was repaired. Approximately 5 years later, the failure reoccurred while driving approximately 70 MPH. The contact was able to get off the nearest exit, then coasted to a stop. The vehicle was towed to the dealer, who diagnosed the same cause of failure. The vacuum pump was replaced again. The manufacturer was informed of the failure and opened a case. The failure mileage was 49,967.

I was driving on the highway and when I exited and tried to stop at a red light the brakes stopped working. No warning, the brake assist engaged so I barely came to a stop in time before hitting the car in front of me. I can barely use the brake pedal and my check engine light came on with it. Its very hard to press the pedal like its got something stuck under the pedal but there was nothing. The brake assist stays on and basically is the only way the car will stop and still doesn't completely stop.
