2015 Chevrolet Equinox — Known Issues & Recalls

Your car is consuming oil faster than normal. You've already had the timing replaced, and now your engine is showing a warning code (P0420) indicating the catalytic converter isn't working efficiently. This combination suggests there may be an internal engine issue causing oil loss and emissions problems. You'll likely need diagnostic testing to identify whether the issue is a faulty catalytic converter, engine seals, or piston rings.

Timing chain tensioner lost tension and timing chain got so loose it would not turn the cams and catastrophic engine valve damage was done! This engine is notorious for this and there are class action lawsuits as a result but no recalls from GM as yet only TSB’s (Technician Service Bulletins). This is going to cost me thousands in repairs and I still owe $8500 on it.

According to our mechanic, our vehicle’s PCV system became clogged and it increased the pressure in our engine and caused the car’s rear main seal to rupture, leading to catastrophic oil loss, loss of power to the vehicle, and engine damage. In our case the entire engine needed to be replaced.

Noticed knocking in the engine and excessive oil usage. I keep my vehicle maintained. I went and had the values and seals replaced around engine for oil. Not even two to three weeks later knocking again. Took it back and engine is burning oil. Read about this make and model having defective pistons and rings causing oil to burn excessively. This has cost me thousands of dollars and it's still not fixed.

My daughter, the driver of this vehicle, noticed a noise. The check engine light came on. Over a short period, the noise from the engine progressively worsened. We brought the car to a certified mechanic. The mechanic's initial determination was that the engine would need to be replaced. It was determined that the engine was faulty, failing due to oil leakage that led to excessive oil consumption. As we were not ready to make that kind of financial commitment, we asked him if there was another option. We were instructed to check the oil frequently. We did so over the next couple of months, but the problem continued and worsened. As my daughter was driving, the engine would make a noise and lose power. Eventually, the vehicle started shaking and would shut down when stopped at red lights and stop signs, requiring the engine to be restarted each time. We then brought it back to the mechanic, and the engine was replaced with a new one.

The 2015 Chevrolet Equinox equipped with the 2.4L Ecotec engine has been reported to have excessive oil consumption due to several issues: Defective Piston Rings: The oil control rings are prone to sticking and clogging, leading to oil blowby and excessive consumption. PCV System Issues: Problems with the Positive Crankcase Ventilation (PCV) system can create excessive vacuum in the crankcase, contributing to oil consumption. Timing Chain Problems: The timing chain can stretch over time, leading to misalignment and potential engine damage. Regular Maintenance: Owners are advised to monitor oil levels frequently and consider using synthetic oil for better performance and longevity. These issues can lead to significant engine wear if not addressed promptly. My vehicle is using too much oil. The 2.4L eco tec engine is installed in this vehicle. The Chevrolet dealership in Rockwall Texas texted me that the engine is bad and needs replacing. The vehicle is past is warranty, so the dealership is using that reason, to not fix this issue. The estimated cost to replace the engine is approximately $11000.00.

The 2.4 liter engine in my car has had excessive oil consumption. now the engine oil is like peanut butter and the blow by out the oil fill is strong.

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.

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.

Excessive oil consumption leading to a broken engine

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 bought a vehicle from a small dealership as a "as is". My passenger side door shifted. Its does not state on the title and I was not told that it was in a accident. I have had this vehicle about a month now. I have a loan against it.

I am submitting this complaint due to a serious mechanical failure involving the vehicle’s transmission system. The transmission developed a fluid leak that resulted in a sudden loss of proper hydraulic pressure, causing abrupt and unintended vehicle movement while driving. This malfunction created a hazardous driving condition and nearly caused an accident. Given that the vehicle has approximately 77,000 miles, this type of transmission failure is premature and raises concerns regarding a potential manufacturing or component defect. Immediate review and corrective action are requested due to the safety implications of this issue.

Hello, on September 5, 2025 I was driving my 2015 Chevy equinox. I was in a collision while driving my 2015 equinox going at a speed of 60 MPH on a highway. On the day of the collision I hit a cargo truck that was carrying vehicles an it completely destroyed the front of my 2015 chevy equinox despite the severity of the impact.

The ref air bag sensor appeared in my 2015 Chevy Equinox today. My vehicle has not been in a car accident as of today 1/24/26. None of my airbags have been deployed at all. I would like to report this defect and I would like Viva Chevrolet in El Paso Texas to be notified since that is the dealership where I purchased based my vehicle. Thank you.

When I was driving down the street, I noticed smoke coming from the hood then flames . I parked off to the side of the road and open the door and took off running away from the vehicle. Loosing everything clothes, phones , jewelry important documents.

Your engine is making abnormal rattling and ticking sounds from under the hood, even though no warning lights have appeared. A mechanic diagnosed this as excessive oil consumption, which may eventually require engine replacement. You've been topping off the engine oil occasionally to manage the consumption.

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.

My vehicle has been cranking when trying to turn on. Sometimes when it does turn on, it will engage the anti theft system. It will also turn on my 4-ways, and windshield wipers other times without me triggering these buttons.

This auto is not driven often due to the fact that the owner is out of town for work more than she is home. The car was driven on a three hour trip when the sidewall of the michelin latitude tour 225/65/r17 tire blew out. She was able to just make it off the road and change the tire.
