2015 Chevrolet Equinox: engine stalls while driving

Filed Aug 3, 2026 · Fuel system · IN

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

While driving my 2015 Chevrolet Equinox (2.4L Ecotec) in active traffic, the vehicle suffered a sudden, catastrophic loss of oil pressure with no prior warning, displaying a 'Stop Vehicle' message. The sudden loss of engine power created an immediate collision risk. Independent diagnosis confirmed the engine lost all oil. This is a known defect (GM Special Coverage #14882) where a frozen/clogged PCV orifice causes excessive crankcase pressure, blowing out seals (like the rear main seal and VVT solenoids) and dumping the oil. I called GM, who told me I needed the vehicle to be towed to a local dealership (White Allen Chevrolet) refused to perform the GM-mandated Manometer Vacuum Test to confirm the PCV defect, attempting to conceal the root cause of the engine failure. This is the only test I asked them to perform, and I provide my GM case number and the TPS number. This known PCV design flaw creates a sudden, highly dangerous stalling condition at highway speeds. It had been very cold in Dayton for over a week, something known to cause this problem.

I took my vehicle to a Chevy dealership due to engine light coming on with the stability track light showing as well as "reduced engine power notification. They are saying the timing chain is needing replaced therefore requiring the entire engine to be replaced. Vehicle is available upon inspection. Once the engine light came on and the reduced engine power light came on vehicle started stalling in traffic. I was at a traffic light and the vehicle cut itself off once I came to a slow stop. Vehicle had to be turned off and back on. Vehicle also started losing power while driving when trying to pull over to incident. Yes. I took my vehicle to a dealership. Initially, they changed other parts on the vehicle. However, when they tested vehicle, it was still showing same signs. That is when they came up with needing a whole new engine based on the timing chain. Dealership will not replace timing chain and states the entire engine needs replaced. Vehicle has only been inspected by a Chevy Dealer. Yes, Once the engine light came on, the stability track and reduced engine power mode came on. they first appeared about a week before i took the car in. I made an appt as soon as the lights came on. The dealership was not available for immediate assistance.

I have contacted GM numerous times about excessive oil consumption in my vehicle. Even with pristine maintenance and making sure that the oil is changed when it needs to be, it is chugging oil. You can’t even drive 200 miles and it’ll be bone dry. Yesterday while I was driving, it stalled out in traffic and almost caused an accident! We were on an extremely busy highway and it just stalled right there! Thank God, the people behind us weren’t tailgating!! I have contacted GM numerous times. There is currently a class action lawsuit because a lot of of the Chevy equinox is burn excessive oil. There was a previous class action lawsuit on older Chevy equinox that was settled. It’s the piston rings and everything that are causing this issue. We’ve also had the previous recall fixed, but for some reason, they will not take it off of our vehicle!! The wiper blades were fixed and we’ve contacted numerous times about that getting corrected as well

GM has long known about the oil consumption problem of the 2015 and settle a lawsuit for the 2013. Car issues including engine shutdowns and stalls, spark plug fouling, engine misfires, unexpected loss of power, vehicle “jerking”. Other people had the same issues included fires per blogs about the issues with the 2014-2015.

Vehicle is stalling when stopping and starting to go. Service engine light came on had it it scanned, found it to be the camshaft position sensor. Called my local dealer as to find out if there is any recall on this, and they said that there is not. I believe there should be a recall on this part as is it is a safety issue, as stated the vehicle was stalling and you lose all power. When starting to pull out in traffic you will be left with no power as the engine stalls and you have to put the vehicle in neutral and restart it.

Took 2015 Equinox into Dealership due to call stalling - not dying. I made an appointment for a few days later. They gave a "fix", and said if it starts doing this again to bring it back in as this was their first guess at what it was. A couple months later it started stalling again. It was a Saturday, this time the stalling happened once and then died. I had it towed to the dealership and they said I had ran the car without oil. I had religiously had the oil changed and had never had low oil when I brought it in even for any oil change. The dealership quoted me $9,200 this time to "fix" it - by replacing the engine. The car has less than 90,000 miles on it.

My SUV uses a lot of oil. I'm not sure where it is going. Also my brakes squeal something awful. ever since I had the car.And it stalls most everytime I stop at red lights or when I park. My check engine light is on all of the time. It simply will not operate at those low speeds. The engine starts to lag and idle really bad. I ran the codes and it said it was the camshaft positioning sensor. I've owned the SUV for 18 months. I don't know what the lemon laws are where I live, but I believe it's a total lemon.

Car all the sudden died while driving and wouldnt start back up. Took it to my mechanic to find out it was very low on oil and timing chain slipped. Both oil consumption and timing chains are common issues in this car. No indication of low oil on the dash and had just added oil the week before. Also had to fix the rear main seal awhile back which caused my car to just stop while driving which is also a common issue due to the design of the pcv.
