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.

The vehicle was taken to a local independent mechanic, where it was diagnosed as needing transmission fluid. The vehicle was repaired. In addition, the contact stated that the failure reoccurred, and the vehicle was taken to another independent mechanic, where the vehicle was diagnosed with missing bolts on the start-stop accumulator impact. The local dealer was not contacted. The vehicle was not diagnosed or repaired. Upon further investigation, the contact related the failure to the federal safety agency Campaign:20V668000 (Power Train); however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 160,000.
The contact owns a 2018 Chevrolet Equinox. The contact stated that while driving approximately 80 MPH, the vehicle unexpectedly decelerated. The contact pulled over to the closest exit and pulled over to the side of the road. The vehicle was turned off and then restarted; however, while attempting to drive forward or reverse, the vehicle failed to move. The contact inspected the vehicle. While inspecting the vehicle, the contact became aware that there was fuel leaking from the side of the engine near the high-pressure fuel pump underneath the vehicle. The check engine warning light was illuminated. The vehicle was towed to a certified mechanic, who diagnosed that the transmission intake failed, causing the transmission to fail. The transmission was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 168,053.
While driving the brake pedal suddenly became hard to push making the car unable to slow down. Put car in neutral and managed to get off street into parking lot and coast to a stop. Car would no longer start. Towed to dealership for assessment. Reports of broken vacuum pump pieces and related metal debris found in engine. Dealership recommended engine replacement. Notified GM, they provided a case number and helped discount the full cost of engine replacement down to $6,225.00 which we paid out of pocket (or risk losing the full value of our equity in the vehicle against a replacement).
Brake system has failed. “Brake Assist Service” has popped up on screen. Taken to two separate facilities who said this is a KNOWN problem with this vehicle make and model.
Got word from the mechanic at the dealership that the cam shaft is leaking oil as well as the fuel injectors retainers are out and need to be sealed as they are also leaking. the engine went into safe mode to prevent any engine fires.
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.

Engine power low
My vehicle suddenly began giving a message engine power reduced. This happened on a highway that required with a maximum speed of 65 mph. My vehicle reduced speed to under 40mph which may be beneath the minimum speed limit. I took the vehicle to a chevvy dealer who said my transmission was slipping. I took it to AAMCO spent 6000 on repairs only to have the engine power reduced error continue to appear. AAMCO claims they have made all repairs yet the light is still on and my vehicle continues to lose engine power on fast highways (the intended interstate). I called chevy because I had seen similar issues in older models and they refused to accept me rendition of events because my vehicle was not serviced by chevy. I tried to upload a photo of the error message The upload is not working.
Vehicle displayed reduced engine power, check engine light, and service brake assist all at the same time. Brake pedal wouldn't move leaving me without brakes. Coasted to stop and shut off car. Brake did not release and now engine won't start. Informed brake vacuum booster pump is problem and ruined motor now.
The contact owns a 2018 Chevrolet Equinox. The contact stated that while depressing the accelerator pedal, the turbo charger failed to operate as designed, and the vehicle failed to accelerate as intended. The contact stated that excessive pressure was needed to depress the accelerator pedal. The message “Engine Power Reduced” was displayed due to a low coolant level. Additionally, the contact was adding 2-quarts of engine oil to the vehicle weekly. The contact stated there was oil on the ground underneath the vehicle. While checking the oil level, the contact saw smoke coming from the exhaust. The check engine light was illuminated. The contact was made aware of the Special Coverage Program, the federal safety agency ID Number: 10171426 (Engine and Engine Cooling, Air Bags, Service Brakes, Hydraulic); however, the year vehicle was not included. The vehicle was taken to an independent mechanic who replaced the oil line connected to the turbo charger; however, the oil leak persisted. The manufacturer was informed of the failure and referred the contact to the federal safety agency Hotline to report the failure. The failure mileage was unknown.
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 while driving at undisclosed speeds, the brake pedal seized while depressing the brake pedal. The check engine warning light was illuminated. The contact was able to pull over to the side of the road and the vehicle eventually came to a stop. The vehicle was towed to the residence. The contact inspected the vehicle and found that a gasket had detached and was missing, and there were plastic pieces inside the engine, and there was oil intrusion into other parts of the vehicle and engine. The vehicle was not diagnosed or repaired. The vehicle was parked at the residence and had not been driven since the failure. The manufacturer was notified of the failure but denied assistance in covering the cost of the repair. The failure mileage was 200,000.
2018 Chevrolet Equinox Premier. The engine connecting rod to the #1 piston separated, causing the engine to stop while the vehicle was in motion. The only warning light at the time was the tire pressure monitor system. The incident had no warning. My husband was driving the vehicle. Initially he thought the car blew a tire by the noise, but then the engine stopped/stalled while I was driving. He was able to get to a side road. The vehicle would not start. He smelled burnt rubber and then thought he broke a belt. He pushed the On-star button for roadside assistance. The car was towed to Ferman Chevolet, Adamoo Dr., Brandon, Florida where they inserted a camera scope and confirmed the rod separation. I do not have paperwork except to show they gave me $2500 towards a trade-in. Over the phone they said it would be $1800 to take apart the engine to confirm the separation. The mechanic suspected the engine was scarred as a result. It would cost $12,000 to replace it, or they could talk to the sales side and see if they can let us trade it in on a different car. We traded the vehicle in. I just saw news of another GM recall affecting the 6.2L V8 and thought it odd that the same thing happened to my vehicle, which is not included in the recall. The engine stall caused my husband to stall in the middle of the traffic lane on a side street. Had he not gotten to the side street in time, he would have blocked a traffic lane on a very busy road which could have resulted in a major accident with injuries.
This rare equinox has a Turbocharge issue that causes rapid engine power loss, and melting under the manifold and around the fuel injector pipes. The recent recalls do not include this GM made diesel equinox due to its rarity, and small consumer ownership of 506,775 units sold in its lifetime. However, GM has been just as negligent with this diesel 1.6L, as with the other major model lineup. Diesel particulate sensor goes bad every year around installation anniversary (previous recall). Stated every year in purchase anniversary month 10/2021, 10/2022
My son was coming home from work 3/26/2025 after 5 pm, when a warning message came on that said "Engine Power Reduced". My son attempted to pull over, however, the brakes did not work. This caused a definite safety risk to my son and others as he could not stop the vehicle. Gratefully, he was on the street and not on the freeway where speeds are higher which could have caused injury or possibly death. He found a clear area to pull over and put the car in park and pushed the start/stop button to turn off the car. The car had to be towed to my home. The car was towed to the repair shop 4/1/2025. There were no previous warning messages regarding the engine or otherwise until the day of the incident. The vehicle is currently in the shop and has been inspected.
The contact owns a 2018 Chevrolet Equinox. The contact stated that while driving at an undisclosed speed, the brake pedal was depressed, but the vehicle failed to stop immediately. The contact had to firmly depress the brake pedal for the vehicle to respond. The "Service Brake Assist" message was displayed. Additionally, the engine made a clicking sound, and the vehicle lost motive power while driving. The vehicle was towed to an independent mechanic, who related the failure to the federal safety agency Campaign Number: 19V645000 (Service Brakes, Hydraulic); however, the VIN was not included in the recall. The vacuum pump was replaced, but the mechanic discovered metal shavings from the vacuum pump in the engine. The contact was informed that the engine also needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to file a complaint with the federal safety agency Hotline. The failure mileage was approximately 107,000.
No code, no indication of anything wrong, no lights or warnings, no sounds or rough running indications on the vehicle. It just completely died in the middle of the highway while traveling down the road and would not restart. Middle of the night with me and my granddaughter in the vehicle. It ended up being a problem with the timing chain which was not broke. Nor were there any indication there was a problem with it.
Camshaft broke into pieces into the engine causing the vehicle to not run on the roadway with minors in the car.
Good afternoon I hope everyone is well. This complaint I'm filing for Turbocharger/Supercharger A under boost condition (P0299) with my daughters 2018 Chevy Equinox. When you research this error with Chevy/GM vehicles you'll see this impacts all vehicles, but Chevy/GM is only recalling their vehicles from 2022+. I've spoken with numerous auto mechanics throughout the United States, and every auto mechanic has stated this is an issue that impacts all Chevy and GM vehicles. Both Chevy and GM are deceiving everyone and there's a significant issue that requires Chevy and GM should address.

I'm writing to request an extension of the recall for the Brake Vacuum Pump issue and seek compensation for repairs on my 2018 Chevy Equinox. In November 2023, while exiting [XXX] in Warwick, RI, my brakes failed despite full pressure. I had to steer into the breakdown lane and eventually stopped in a parking lot. At the time, I was nine months pregnant and extremely shaken. After stopping, the vehicle exhibited erratic behavior and not stopping, entering "limp mode." The car was towed to a local mechanic who initially thought the brakes were at fault. It was later diagnosed at Sullivan Tire that a "catastrophic failure of the Brake Vacuum Pump" caused camshaft damage, leading to repair costs of $3,197.17. The mechanic stated this failure was unprecedented for a vehicle with only 64,271 miles. I discovered that a recall for this issue exists but does not cover the 2018 Equinox. Many owners of this model have reported similar problems. Requests: Recall Extension: Please extend the recall to include the 2018 Equinox and other affected models to prevent further incidents. Compensation: I seek reimbursement of $3,197.17 for repairs. I have documentation and faulty parts available for inspection if needed. I have contacted Chevy and they have not been helpful, and this needs to be filed for a full recall. Attached are the repair invoice, proof of faulty parts, and links to related complaints. I look forward to your prompt resolution to prevent future issues for consumers. I still have the damaged parts for proof failure in my possession.

Vacuum pump failed and broke with no warning signs at all. After replacement now it will not start well and when it does I have lose off power. Lost brakes while driving on a country road and had to have it towed.
Brake assist light went on, had the brake pads and rotors replaced, light went off. 6 months later the light came back on but this time the brake pedal was hard. I did not drive it after that. After looking online and seeing dozens of people with the same issue, I took a chance and bought the brake booster and had my friend, who is a certified mechanic, replace the part. The old vacuum pump had frozen up and broken along with the gears, which had fallen into the engine, just like what I was seeing all over the Internet. People are getting hurt and lives are at risk, this should have been recalled!!!!
P0299. Engine power reduced [XXX] mileage 95617 Charged air cooler needs to be replaced. P0299 [XXX]. Mileage 96101. Turbocharger O.E. REPLACEMENT replace Turbocharger Assembly. P0299 [XXX] engine power reduced. P0299 [XXX] engine power reduced. Mileage 68340. Engine light goes on and off. The code P0299 is a code where my engine light comes on. Then after calling the dealership Miller Brothers Ellicott City, MD With my concerns that the light is on again but by the time I'm given a service appointment the engine light goes back out. I feel that this continues to happen with my vehicle several times while my car was covered by my extended warranty as well as my 100 thousand miles powertrain where in which my Turbocharger is not functioning correctly and should be made part of a recall of All Chevy equinox vehicle which have the 1.5 liter engine where the engine power reduced code P0299 APPEARS the goes out on its own knowingly Even though my car VIN is not part of a recall it remains a safety issue for myself as well as other Equinox owners. It's like I think I am having a heart attack today (reduced engine power) But My local Chevy dealerships want me to make and appointment. This needs to be replaced and repaired by the dealership at no cost. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
