The PCV Valve froze last week causing pressure to build up and blew the rear seal. All the oil leaked out and caused a grinding noise and the vehicle shutoff on its own. This I have seen is an ongoing problem with the Chevy Equinox. I was quoted $3800 from the dealer to repair.

- Louisville, KY, USA

Rear main seal gone bad due to engine defect noted in GM service bulletin pip5093C which is a known defect in the engine.

- Crestwood, IL, USA

Oil leak caused by insufficient ventilation and excessive oil burning caused rear main seal and timing chain belts to fail. Oil warning systems were too late in warning about problem until engine stalled out and all oil was consumed, causing engine failure. No low oil warnings came up until minutes after the initial engine shutdown. Research has shown that this has been a known chevy problem since 2017, with a recall being issued earlier on but no known recall now. Dealer has confirmed issues and also that the engine design is flawed and leads to oil burning excessively

- Buffalo, NY, USA

Vehicle stalled when driven or stopped at traffic light. Abnormal noises coming from engine. When engine oil was checked, no visible oil was available in the dipstick. Inserted dipstick a couple of times to ensure correct measurement. Extremely low oil left in vehicle. Vehicle seems to be burning oil. Diagnostic trouble codes read by obd2 tool were: P0011, P0191, P228D, P0089 and P0014. When investigating online, this is a common problem with the vehicle's engine. This seems to be a design flaw being ignored by the oem.

Driving down a 4 lane busy highway. Going 65 when the car made a pop sound. We pulled over. Car caught on fire 5 mins after we were out

- Punxsutawney , PA, USA

Had car over 5 years from 11/2019 to current and had no issues at all. No check engine lights, nothing, and kept up on all routine maintenance. Car started up just fine drove on interstate from about 10 miles came to my exit and vehicle turned off and tried to restart itself. Car never started again. After getting it towed home replaced the started and that wasn-??t the issue towed it again to Firestone they could tell me what the problem was because they don-??t do engine work. Finally took it to a Chevy dealership who stated the timing chain broke and we need a whole engine replacement for $9600. Now we are stuck without a vehicle because of know issues GM AND Chevy have been aware of.

- Omaha, NE, USA

Car is 7 years old and only 65,900 miles (purchased new and oil changed every 4000 mi) when timing chain noise started - approx April 2024. Chevy dealer in area and independent mechanic could not find the issue and diagnosed as exhaust sound though Chevy has known issues like this with 4 cylinder engines). Car was traded Aug 2024 (has since been sent to auction due to unknown engine damage) and discovered upon trade it had catastrophic engine failure. For months car was driven at times with small children when engine could have seized up and caused a crash. No engine lights or indication of an issue other than diesel engine sound when car was running.

I bought my 2017 Chevy equinox around October or November of 2018. Since owning this car I have had nothing but problems with the oil. The oil had been burning at such an excessive rate that GM finally stated they would need to replace the engine! I have continued to change the oil before it need to be changed due to it burning so quickly. After the engine was replaced I informed GM of the loud noises and informed them 3 weeks after they replaced everything that the oil was again empty! They are now ignoring me and won-??t do anything further! I am a single mother of 3 kids trying to make ends meet and I bought a car they knew and have known has oil consumption issues which has caused my car to have major issues. The car randomly can to a full stop while I was driving and I am so lucky I wasn-??t going 80 miles an hour because it would of killed me all because the car had burned the oil just 2 weeks after an oil change! GM continues to ignore me and will not replace the car or fix anything! I started having issues in August of 2019 and they replaced the engine on jul 14 2022 and I am certain this car is not going to make it much longer it has ac and heat problems as well again all started after replacement and still have oil issues

On 2-11-24 a light came on about system reset plus speed reduced to 20. I drove home 4 miles. Called Chevy Corp. Told needs to be checked. Dealership said if drivable come in.Light was safety to get off Rd or to garage. Timing chain slipped and chewed up teeth spreading metal everywhere and killed motor. No warning. It's a known prob with Equinox as I have seen class action lawsuits. Advisor even said need another lawsuit to solve it. Tried going thru insurance but advisor said normal wear and tear. Chevy dealership or corp will not help or give me a rental car. $10300 to get a refurbished motor and hope it doesn't happen again. Same car burns oil had sensor issues on block and every 1-2 years battery dies. Paid 65 to replace it one time under warranty. Timing chain doesn't slip they break to stop car. Advisor says a few mechanical issues caused it. To me it shouldn't do that if made rt. I could have been in an accident if on highway. Insurance won't cover under comp part of policy yet if hit and totaled it's paid.A diff garage said belt or chain shouldn't need replacement until 100k miles. I only have 77k.

I am writing to address a critical issue involving my 2017 Chevrolet vehicle, which poses a significant safety hazard. I purchased this car from Faulkner Subaru in Bethlehem in 2022. The specific component failure relates to the positive crankcase ventilation (PCV) system, particularly the lack of a traditional PCV valve and the presence of a fixed orifice vacuum port in the intake manifold. This component is available for inspection upon request. The safety of myself, my passengers, and other road users was compromised due to the sudden and significant oil leakage caused by the malfunctioning PCV system. This not only endangered our safety but also posed a serious risk to others on the road. While the problem has not been reproduced or confirmed by a dealer or independent service center, it is a well-documented issue with ongoing litigation against Chevrolet. However, there are currently no active recalls addressing the problem. There were no warning lamps, messages, or other symptoms of the problem prior to the failure. The incident occurred suddenly while driving, with the strong smell of burning oil and subsequent oil leakage being the first indications of a problem. Your immediate attention to this matter and intervention on behalf of affected consumers is crucial. I urge Chevrolet to address this safety concern through a formal safety recall and to take responsibility for rectifying this manufacturing defect.

While I was driving the rear main seal went out and I lost all my oil. Luckily I was close to home, could have blown my motor. This is a $1500 to a $2500 fix. This happened around feb.26 2024 and my car is still sitting I'm my drive until I can save up the money to fix it. Also the few places I have called around to fix it have had other equinoxes in for the same thind,22 that I know of.

I was driving when my car started knocking. I pulled over on the highway and noticed oil all over the undercarriage of the vehicle. I immediately drove to the dealership and had the mechanics take a look. They came back and said, "The rear main seal was leaking due to a plugged PCV port that froze because of the cold weather. This caused high crankcase pressure to build, which blew out the rear main seal." Looking online, I found that this appears to be a common problem. The dealership said they could fix it by drilling the hole in the PCV port bigger, but there is currently no recall on this issue. Just to replace the seal, they are charging $2500, with an additional few hundred dollars to enlarge the PCV port. Thankfully, I was able to pull over and get it to the dealership. I can only imagine how bad things could have been if I hadn't been in a relatively safe spot.

I was driving my vehicle when it started putting at a red light. I was close to my place of employment so I drove it the few blocks there and parked it. When I went to start it on my lunch break I heard a bunch of rattling under the hood and it wouldn-??t drive. I checked the oil and realized All of the oil had leaked out.

My son was driving and all of a sudden the check engine light came on, it got really loud and stalled out while he was driving. Luckily he was on a road with a low speed limit. If this had happened on the highway it could have been extremely dangerous. He is a 16 year old new driver. We took it in and were told the rear main seal blew and we need a new engine. Apparently this is a know issue with this car. We are now in the process of installing a new engine on a car we have taken very good care of with less than 100,000 miles and still has a car payment. There were no prior warnings and the issue was confirmed by the dealer.

Car started to leak oil, took it for repair was told it has a pcv valve issue, that can lead to main seal failure. This is a 13 hour repair, at a cost of approximately $2500 This issue can happen again, and especially in cold weather. So even if you get it repaired this pcv/valve issue can cause main seal failure again. From Mechanic Report: -??Finding:.Other engine oil leak issue -??Recommendation: See technician notes below -??Technician's Notes: Rear main seal leaking. Lower oil pan very likely leaking as well. PCV system failing caused Excessive engine pressure which in turn caused rear main to fail. There is a GM TSB specifically for this issue. Without repairing PCV, seals will fail again. Repairing PCV system will require intake and valve cover removal. -??Full recommendation: -??-Remove valve cover and clean pcv passages -??-Remove intake, replace pcv valve, and clean pcv passages. -??-Replace rear main seal -??-Replace oil pan seal My vehicle mileage is Odometer 68,201mi so I am out of the warranty window.

Took the vehicle in due to poor function to be addressed and the vehicle was found to have no oil in the engine. 5 quarts of oil was just placed in the engine at the beginning of the week and was told that the engine is burning oil very badly. This is very concerning as I am seeing that other people are having this exact issue, often while driving on the highway. We are only driving this vehicle if absolutely necessary and do not have the money to replace the engine and the pistons. We have been diligent with frequent oil changes but we cannot keep pouring oil in this vehicle only for it to be gone within days or hours. This is a huge safety risk and could cause injury or death to myself, my children or others on the road. The check engine light came on after the oil was added. Took to our mechanic and they confirmed that the entire engine or at least all the pistons will need to be replaced in order to make this vehicle safe for driving. Called General Motors about this issue and was informed this very vehicle is in class-action lawsuit for the very same thing my vehicle is experiencing and that a recall should be coming out, but no one knows when this recall will come out. This is a common problem seen with the equinoxes and it needs to be fixed by the dealer or General Motors.
