Chevrolet Equinox overheating problems

Filed Sep 13, 2026 · Brakes, Engine · IN

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.

Component Failure & Availability: A GM remanufactured 2.4L engine block, installed as a replacement in July 2025, suffered a catastrophic internal failure (blown head gasket) within 11 months of installation. The vehicle and the component are currently in the owner's possession and are available for inspection upon request. Safety Risk: A blown head gasket with an internal coolant leak into Cylinder #3 causes immediate engine overheating, severe engine misfires, and a loss of motive power. If this defect causes the engine to stall while the vehicle is in motion, the driver suddenly loses power steering and acceleration, directly compromising the safe operation of the vehicle in traffic. Confirmation by Service Centers: The catastrophic failure was formally reproduced, pressure-tested, and confirmed by an independent service center. Inspection by Manufacturer/Others: Following the independent confirmation, the vehicle was inspected by an authorized manufacturer dealership. During this inspection, the authorized dealership executed an unauthorized teardown of the engine block and sublet the engine head to a third-party machine shop, physically altering the failed component prior to manufacturer review. Warning Lamps & Symptoms: A check engine light illuminated shortly after the engine's initial installation. The authorized dealership evaluated the vehicle, reset the diagnostic trouble codes (DTCs), and released the vehicle back onto the roadway without properly diagnosing the warranted engine block. This allowed a defective and degrading powertrain component to remain in operation until failure occurred.

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.

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.

My wife and I were driving to Galveston on I-45 and were driving through La Marque when our car suddenly lost power. I started moving over to the outside lane and went to turn on the emergency lights. I realized the lights were already on. We heard a thump and thought that the serpentine belt had broken and that the engine would overheat, followed up by white smoke coming from the dash vents. My wife opened her window and leaned out the window while I tried to control the SUV without power. A truck pulled next to us and the passenger screamed that our car was on fire. I stepped on the brakes, but my foot went to the floor without effect. I hit the button for the emergency parking brake, but it didn't stop the car. I let the car slow down and then black smoke was coming from the vents. We were choking from breathing the smoke and I tried to open my window, but all electrical systems had quit working. The car finally slowed enough for me to shove the gear shift into park. My wife jumped out of the car and fell to the pavement, also hitting the concrete barrier on the side of the highway. My seat belt was stuck and I kept pushing the button and reached for my pocket knife to cut the belt when it released. At this point, flames were coming from the vents when I reached for the door handle and open the door. I fell out of the car onto the highway, rolling away. I was finally able to get up and saw several vehicles stopped behind us, but some were still driving through. I got away from the car and found my wife who was being helped by another man who stopped ahead of us. The car was on fire, mostly from the back, heavily in the left rear where the gas tank is. The car was completely burned and an unknown retired firefighter said all of the signs point to a defective fuel pump.

Timing chain malfunction caused the engine to completely fail and the car is now unroad worthy. Did oil changes frequently due to fast consumption of oil. Never overheated but now the cylinders, oil pump and heads are no good and a rebuilt or new used engine would be required to repair the car.

This past weekend, while driving my 2020 Chevrolet Equinox, I experienced a sudden and complete brake failure. I was turning into a residential neighborhood at approximately 20-30mph when the brakes locked up without warning. Despite pressing the brake pedal, the car would not stop. I attempted to shift into park, but the vehicle continued to roll forward. I had to engage the emergency brake, which caused the car to come to an immediate stop. Thankfully, there were no cars in front of me, but I came dangerously close to hitting a cement wall head-on. This created a serious risk to my safety and potentially to others had the situation occurred in traffic or near pedestrians. There were no warning lights, noises, or prior symptoms indicating an issue with the braking system. The vehicle has since been towed to the dealership and is currently awaiting inspection. I've learned that there are existing recalls on other VINS for the 2020 Equinox related to an incorrect lubricant used in the manufacturing process of the rear brake calipers. This defect can cause the calipers to swell, leading to excessive brake drag. Over time, this drag may result in overheating and possible brake lockup, which aligns with what I experienced. The component appears to be the braking system, specifically involving the calipers or pads. At the time of writing, the failure has not yet been confirmed by the dealer. This issue is extremely dangerous and could have resulted in a severe crash. I am reporting this in hopes that it contributes to a broader investigation, especially if this problem extends beyond currently recalled VINs.

The contact called on behalf of the owner of a 2019 Chevrolet Equinox. The contact stated that there was coolant leaking from the engine compartment. The vehicle was driven to the contact and to a local mechanic who diagnosed that the coolant expansion tank recovery hose had failed causing engine coolant to leak from the hose onto the PCM. The contact stated that the hose needed to be replaced. The vehicle was not repaired. The contact was concerned that due to the location on the hose the failure would reoccur once the hose was replaced. The manufacturer and local dealer were not yet contacted regarding the failure. The failure mileage was 49,549.

Engine and coolant system. The engine consumes the oil. Burns the oil way too fast. Also the cooling fan is inoperable. I’m afraid the car will overheat. Check engine light is on.
