2015 Chevrolet Equinox fuel system problems

FUEL/PROPULSION SYSTEM

1. High Pressure Fuel Pump, and yes. 2. Car will stall out unless I put it into neutral, shakes on shut down and sometimes starts scary fast. With the car caring my children in a busy town this is a HUGE safety hazard 3. No, but has been inspected by multiple mechanics. Got a tune up in May of 2026 problem subsided and back now. Numerous people have problems with this specific model of car and the HPFP. 4.PO0172 code, but that is the only code that has been persistent. No other known problems with the car. I have reached out to GM because there is no recall on my VIN number for the High Pressure Fuel Pump, but numerous Facebook groups for "Equinox Problems" have this issue and I would consider that a manufacturing problem of these Models (any year). Some people with the 2010 models had recalls, some newer but I have the same EXACT issue they are having but no Recall as of yet. I just want my issues to be known and addressed

Excessive oil consumption leading to a broken engine

NHTSA complaint #11711172 — an unverified report by a vehicle owner.

FUEL/PROPULSION SYSTEM

My 2015 Chevrolet Equinox has a cracked exhaust manifold, a known issue affecting many vehicles of this model. When using the heat or air conditioning, gas fumes enter the cabin, creating a serious risk of carbon monoxide exposure. I regularly transport my two young children in this vehicle, and we are forced to drive with the windows down in cold weather to reduce the risk. The vehicle also consumes oil and is still being financed. Despite the manufacturer being aware that this is a widespread problem, I am being quoted nearly $2,000 for the repair. This poses an immediate and serious threat to the health and safety of my children and myself.

FUEL SYSTEM, GASOLINE

The contact owns a 2015 Chevrolet Equinox. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. While the vehicle was stopped at a traffic light, the vehicle jerked and idled roughly and nearly stalled. The vehicle was taken to Auto Zone to be diagnosed. The contact was provided with DTC P0172. The vehicle was not repaired. Several days later, the vehicle was taken for an oil change, and transmission fluid was flushed and refilled. The contact stated that on a separate occasion, a week after the oil change, the check engine warning light illuminated. The contact took the vehicle back to Auto Zone to be diagnosed. The contact was provided with the same DTC: P0172. The vehicle was not repaired. The contact stated that the failure persisted. The vehicle was then taken to the dealer. The contact could not leave the vehicle at the dealer. The contact spoke with one of the mechanics at the dealer, who suggested that the high-pressure fuel pump may be the cause of the failure. Several days later, the contact took the vehicle to the dealer, where it was diagnosed and determined that the high-pressure fuel pump had failed and needed to be replaced. The contact was informed that fuel had leaked into the engine through the PCP valve and caused the fuel to run rich. The vehicle was not repaired. The vehicle remained at the dealer unrepaired. The manufacturer was not notified of the failure. The failure mileage was approximately 197,000.

FUEL/PROPULSION SYSTEM

I lost power in the middle of a clover leaf intersection without any previous indicator lights. I was barely able to get to a small shoulder and almost got hit by other vehicles. I was able to restart the car and get to a safer location. The timing chain was failing amd the engine oil was gummy according to the mechanic. I was barely over 100,000 miles. Vehicle oil had been regularly maintained with Mobil 1 15,000 mile oil and never showed as low during checks. Throttle body was covered with carbon and the codes came back for the VVT. Timing chain was replaced but the engine lost compression a few months later. All known issues with this engine and I lost tens of thousands on GM’s negligence. Not to mention the dangerous driving situation I was put in with absolutely no warning.I have been sick over the situation for a fee years but thought maybe the information could help others avoid the same fate. Repair total was $9000 plus because so many of the same model was having problems and there was a shortage of replacement engines. Auto part stores started selling crate engines because of the know issues with this engine.

The incident except for by my 2015 Chevrolet Equinox has major electrical faulty ends in and timing belt changes which causes the vehicle to stall on a consumer at any time for me I was driving on a major highway or five Lanes going to work and the car decided to slow down and started shedding off thank God that I made it to the far right side on a media strip and was able get the car to safety on the knee issue but she did slow down and shut off identity media call the triple A for help and roadside assistance they came as soon as they could and then test the car to see if it was the battery or the alternator which I had put in two brand new batteries and two brand new alternators and still have both he test them all and said no he's been pulling cars off major highways that are Equinox and terrain class action lawsuit against General motors in Chevrolet due to faulty issues in the engine and they recently One cases from 2010 to 2014 although my car is a 2015 the same issue still arise my car has 85,000 miles on it when this happens and I kept up the oil change and the maintenance on the car I then in turn had the car towed to a Chevrolet dealer and turned it a diagnostic test on my car vehicle and this is what they said in my car has the same issue that is from the previous lawsuit of Equinox 2010 to 2014. Have the results are as is fun the Chevrolet GMC dealer the vehicle will not start, the problem and issues extend from the timing belt chain, valves, blown gasket, fuel pump,this is causing many major issues along with all the recalls with the 2010 and 2018 Chevrolet Equinox and Terrain. The only thing that they recommend is that the car engine needs to replacement to make consumers feel safe in their vehicles. Although my car is a 2015 I only have 85,000 miles and I continue to do all the maintenance and I was told by another mechanic that it does not have nothing to do so much as the oil change they knew that there were faulty issues with timingbelt

FUEL/PROPULSION SYSTEM

To Whom It May Concern, I am writing to formally file a complaint regarding my 2015 Chevrolet Equinox, which I purchased used approximately one year ago. Since acquiring the vehicle, I have experienced severe and excessive oil consumption as well as ongoing fuel injector problems. Specifically, the vehicle requires additional oil every 100 to 200 miles, which is far beyond what is considered normal or acceptable for a properly functioning engine. I have not noticed any external oil leaks, and there are no warning indicators until the oil levels are dangerously low. This not only puts the engine at risk of damage, but also presents a potential safety hazard while driving. In addition to the oil issue, I have experienced fuel injector malfunctions which affect the car’s performance and reliability. This has resulted in rough idling, reduced fuel efficiency, and difficulty accelerating at times. I have come to learn that many other owners of the 2015 Chevy Equinox are reporting the same issues, particularly with excessive oil consumption related to engine design flaws. I believe this is a manufacturing defect that should be addressed by GM and reported as a recall or service campaign due to its widespread impact and potential risk to drivers. I respectfully request that the NHTSA investigate this matter further to determine whether a recall is warranted and to encourage General Motors to take responsibility for this recurring issue. Thank you for your time and attention to this matter. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle stopped running. We brought it to the mechanic. The mechanic confirmed that it is a high-pressure fuel pump malfunction and a known issue with these vehicles. All the oil has leaked out because of this issue, which could cause a fire. There is a huge charge to replace this and the spark plugs which were affected by the leak. There is a recall for certain 2015 equinox is because of this very issue, however ours is not covered for some reason. We would like to make a formal complaint so that our vehicle can be covered under this issue like the other 2015 equinox with a high-pressure fuel pump malfunction.

My car received an oil changed recently and then shortly after my engine went completely out due to having no oil. My timing chain stretched out and broke resulting in no compression to my engine.

FUEL/PROPULSION SYSTEM

my 2015 Chevrolet equinox 2.4l ecotec AWD vehicle with 102k miles had a massive oil leak in jan.2022, when it was -22 deg. f outside. The car was at work outside, and my drive home was about 7 miles. When I got home, I decided to check the oil on the dipstick and it was empty. The whole underside of the chasis was oil splattered. I added 3 quarts of oil and started the car up and oil was poring out of the rear main seal. I trailered it to a chevrolet dealer, and they said the pvc frozen up. The engine and subframe will need to come out.This was an expensive repair. This vehicle does burn oil. It does not leak oil thou. The engine oil light never came on during the ride home. I am glad I checked the oil, because the engine would have quit running on the freeway somewhere.

Fuel shut off does not work properly, extra fuel will spill out before the station's gas nozzle shuts off. Happens at every gas station, every time. Spilling fuel is a significant safety issue and environmental concern. Very surprised there hasn't been a recall yet.

Issue with oil consumption on this vehicle. Needs 2 quarts of new oil every 2-3 weeks with moderate driving. Mechanics say this is a known issue with Chevrolet Equinox’s since 2011. The only true fix is to replace the engine and even then the problem can reoccur with new engines. I have joined a Facebook page called “Terrain-Equinox Oil Consumption Recall” with thousands of members experiencing same issue. There is no assistance from dealerships to assist in covering repair costs. There was a limited recall for model year 2013 but same issues are present in 2014’s and 2015’s as well. There are also many complaints about on this issue on this bursa website. Looking for any assistance.

Engine cut off while driving. Happens while driving slow or fast, side road or highway. No check engine light. Timing chain issue, $2500 fix. I've had the car 6 months, only 77,500 miles. I do not feel safe in this vehicle any more. RECALL THIS before people have to bury their families due to your faulty parts. Thank goodness no accidents resulted in my 4 experiences.

MY VEHICLE STALLED RECENTLY WHEN I WAS DRIVING SLOWLY COMING TO A STOP.. PRIOR TO THE STALL WHEN I TURNED MY CAR ON IT MADE A TICK SOUND BUT DROVE OK UNTIL IT STALLED. I WAS ABLE TO GET IT STARTED AND DROVE HOME. WHEN I CHECKED THE OIL THERE IT WAS EMPTY. I WAS WELL UNDER THEM TIME BEFORE I NEEDED MY NEXT OIL CHANGE. I HAD IT DIAGNOSED AND WAS TOLD THAT IT WAS A PISTON AND RING ISSUE THAT WAS THE SAME THING DESCRIBED IN THE CLASS ACTION LAWSUIT INVOLVING 2010-2013 EQUINOX. BECAUSE MINE IS A 2015 I RECEIVED SOME COST ASSISTANCE BUT PAID $1200 OUT OF POCKET FOR THE FIX. SEEMS LIKE GM KNOWS ABOUT THIS ISSUE BUT HAS NOT LET CONSUMERS KNOW ABOUT THIS SAFETY CONCERN. I WAS UPSET BECAUSE I DRIVE WITH MY CHILDREN WHO ARE 3 AND 1. GM NEEDS TO TELL THEIR CONSUMERS ABOUT THIS PROBLEM.
