Crankcase (pcv) Problems of GMC Terrain - part 2

On a cold 12 degree day on 1/19/2020 I was driving my 2013 GMC Terrain on a busy state highway doing the speed limit of 55 mph. Out of no where I began to smell the odor of burning oil and seen white smoke coming from the rear of my vehicle. As soon as I noticed it my car's gauges started coming on. The check engine light, a warning to for "service stabilitrak", then the warning for "engine power reduced". At the moment my car all the sudden shut off while driving down a major highway! there was no power steering and it was very hard for me steer my car into the parking lot of walmart and safely off the road. Once in the parking lot I got out of the car and checked my oil. Smoke is rolling out of the dipstick shaft. I check my oil weekly due to gm's oil consumption issues with the 2013 GMC Terrains and on 1/15/2020 the oil was at full, was of normal color and consistency when I fueled and checked it that day. So I was shocked to see that there was no oil on my dipstick and instead a milky brownish sludge on it. I sent my fiance to buy me 2 quarts of oil just to get it to the walmart service department so they could look at it since I was in the walmart parking lot. I added the oil drove it 100 yards to the service dept of walmart. The service man pulled it into the garage and then informed me a few minutes later that the rear main seal blew and oil was flowing out of it. It was not driveable so I had to have it towed to a gm dealer. The gm dealer called me this morning 1/21/2020 to inform me that the rear main seal blew due to moisture in the intake and a froze the pcv module and caused to much pressure to build up and blew the seal. The dealer quoted the repairs to be $2065. 69 and informed me that the repairs are not covered under the gm service bulletin #14882 because my VIN number is not included in the service bulletin.

Rear engine seal blew according to bulletin 14882 March 2015 caused by a frozen pcv valve. Purchased the vehicle used from a gm dealership as a good used SUV. When reporting the problem,they said there was no bulletin,changed their mind,but said VIN disqualified it for repairs and said I had bad luck vehicle is unusable as it blows oil thru the seal when in operation.

Purchased car used from GMC dealer 88,706 miles. 1 previous owner thta purchased from gm dealer new, I purchased extra 100,000 warranty in addition. I drive about 10 miles total a day about 3 days a week to work, so I have not put many miles on it. 30 days after purchase when driving home from work got to driveway, car dumped large quantities of oil on driveway. No warning lights ever came on to indicate a problem. Diagnostics should have indicated pressure build-up. Car had hesitated a bit at the last stoplight before my house on the way home but not bad and only one time. Oil all over underside of vehicle. Towed to dealer, gm knows of the issue but my VIN is not on "the list" for the "service adjustment" not a recall but it should be. . Nobody can say why. Will cover part but not all of the damage despite this being the result of a really poor engine design that is a "high oil consumption" vehicle. Is this the 70s? that should not even be a thing in 2019. The oil sludge in engine caused the pcv to freeze up in the cold temps and it blew out the rear main seal for the engine. They want $1300 from me to fix and gm is covering part of the cost. But if it is a design flaw and they knew about it, they should have fixed it before they sold it. Extended warranty will not cover this because they do not include the pcv. Likely will not ever cover anything with the engine since it is a design flaw and those are by definition pre-existing and high oil consumption that is not coming out on the ground is fouling up something. So my first payment is not even due yet and I already owe money to someone else and it is significant money that will not be easy to pay. If this had happened on the highway, I would have lost use of the vehicle at high speed and would likely have caused a crash.

Tl the contact owns a 2013 GMC Terrain. While driving 30 mph, the engine made an abnormal noise and smoke emitted from the exhaust without warning. The engine began to stall and the contact pulled over and attempted to place oil in the vehicle; however, the oil leaked out. The vehicle was towed to steven lust automotive (1314 6th Ave sw, aberdeen, sd 57401, (605) 277-4261) where it was diagnosed that the pcv valve was faulty. The contact stated that there was an unknown manufacturer recall that was placed on her year, make, and model vehicle; however, the VIN was excluded. The manufacturer was notified of the failure and informed the mechanic that the contact's VIN was not included in the manufacturer recall. The vehicle had not been repaired. The failure mileage was 61,067.

The pcv system there's plugged up dumping oil into the intake and to the throttle body oils in the intake manifold crankcase too much pressure.

Tl the contact owns a 2014 GMC Terrain. The contact stated that soon after receiving an oil change, the oil warning light illuminated. The vehicle was taken to an independent mechanic to be diagnosed. The contact was informed that the pcv valve was clogged and needed to be replaced. The vehicle was not repaired. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was unknown.

I was on my way home from work driving on the expressway, then all of a sudden every light on my dashboard came on. . . Then my vehicle said reducing speed. I was able to get on the shoulder before it turned off completely. I had to wait for a tow truck for 2 hours. It was cold. I had to tow it to my house because the place that I previously went to was closed and I couldn't leave the vehicle there. So, it was towed to the shop the next day and I was told that I needed a new engine. Engine failure due to lack of oil from blown rear main seal. Seal blown out due to pcv.

Rear main seal failed due to clogged pcv valve. One day the car seamed fine, no visable oil leaks, the next day, daughter backed out of driveway and there was a large puddle of oil under her vehicle. She didn't see the puddle, all the oil leaked out of the vehicle, no engine light came on, had to have it towed to shop, $1200 estimate to repair. This is a known issue with gm.

My wife came home from grocery shopping , as we were emptying out the car we noticed a puddle of oil under the car. There was at least a quart of oil on the floor , I looked under the car and could see that it was the rear main seal on the engine. Then I went on the internet and found out that this is a problem on this particular engine of gm , and on most of the cars this happened to gm does not cover it. It ended up costing us $1142. 44 to have it fixed. Since then I have twice taken off the intake , pcv tube and cleaned it out and found excessive moisture in them. This engine also has excessive oil consumption , there was a lawsuit against gm about this and our car is getting new rings installed. I'm hoping this will also solve the rear seal problem. This is a 2013 GMC Terrain , 2. 4 liter engine.

I was driving when my car started making a noise and vibration. I drove it 3 miles as the vibration and noise was getting worse to the dealership. According to the dealership the engine pcv valve became clogged with sledge or ice and pushed the oil out the rear seal of the engine causing failure. In addition the ecm failed to display a low engine oil warning or a check engine warning. After talking to the mechanic at the dealership and researching on the internet, this is a design flaw for the 2. 4 ecotc engine that gm has failed to address and is causing people thousands of dollars. My repair will cost $3000. 00. Recall 14882.

Pcv system has a service bulliten on this. Pcv system froze uo causing the rear main seal to blow out.

This (normally-garaged, 1-owner, religiously-serviced at dealership) vehicle had sat outside for 38 hours without being started. Vehicle was started in +4 degree f temperature, allowed to warm up, driven 15 minutes on a 2-lane road before stopping at a stop sign. Engine began chugging heavily as it left the stop, attempting to cross 2 lanes of a divided 4-lane highway before turning left in the other 2 lanes of that highway. With engine losing power, driver managed the left turn and pulled off on right shoulder just as engine suddenly died. Just as it died, driver noticed a briefly-lit dashboard indicator signifying something about oil. Vehicle was 3 months past 6-year warranty. It was hauled some 200 miles to the original gm dealer, offloaded in parking lot on Sunday eve. Dealer was informed next morning, and later responded that it would need a new engine. Owner visited dealer, noticed vehicle had not been moved since dropping it off, but dealer somehow knew engine status. Manager was surprisingly understanding. Rear seal was blown, likely pcv orifice issue (as in gm TSB 14882). Dealer said gm would pay 45%, TSB 14882 would cover $400+, dealership would pay half the rest. Owner respects/appreciates dealership's cooperation, but remains concerned about potential danger of sudden loss of power while crossing 4 lanes of high-speed traffic. Owner learned about TSB 14882 only after this incident, only via google, prior to visiting dealer. Owner still doesn't know if VIN is on the TSB 14882 list, which, if it is, should have led to a preventive fix prior to this incident.

The rear main seal on the engine blew out while driving due to the pcv system being faulty. My car died in the middle of a busy intersection without warning in 10 degree weather with negative 10 degree windchill, leaving my family and stranded without the ability to even get heat into the car.

My year make and model with the same 2. 4l engine was subject to a recall/ service bulletin #14882 which pertained to a plugged pcv orifice in the intake manifold which resulted in blowing out the rear main crankshaft seal which could result in engine failure and a warning that the spaying oil can result in loss of vehicle control. A mechanic confirmed that this was the problem I have, yet gm will not cover the repairs as they said my specific VIN was not covered. The vehicle has low mileage and I think it is outrageous that gm will not stand behind their product. The repairs will be very expensive.

During the polar vortex (Jan 2019) my main oil seal blew on my 2013 GMC Terrain. This was caused by a plugged orifice within the pcv system. This appears to be a design flaw on gm's part that they have recognized and extended special coverage as a result. Despite this special coverage existing they state my VIN number isn't included. My problem and vehicle meet the requirements for the special coverage exactly and nobody can explain why I'm not included. If you search online there are lots of other gm owners experiencing the same thing. This blown oil seal can result in damage to the engine and loss of power. Had I been on the interstate a serious accident could have occurred. The fact gm knows about the problem and is refusing to address is my issue. Special coverage 14882 https://gm. Oemdtc.

2013 GMC Terrain with 72k miles (about 5. 5 years old at the time). In frigid temperatures (-15 degrees fahrenheit), the vehicle rpms started fluctuating wildly while in idle, and would shut off entirely. The pcv port froze and lead to blowing out the rear main seal. Dealership told me it was not under warranty (despite the existing power train warranty and service bulletin 14882). Also the exhaust manifold was cracked (which should have been covered by the emissions warranty). Total repair was $2,800.

Tl the contact owns a 2013 GMC Terrain. While driving approximately 35 mph, the vehicle shut off without warning. The vehicle was towed to an independent mechanic where they stated that they were aware of the failure. The technician stated that the positive crankcase ventilation hole in the intake manifold was too small and needed to be replaced. The dealer was not contacted. The manufacturer was made aware of the failure and stated that the vehicle was out of warranty and that there was no recall. The contact was informed to call NHTSA. The vehicle was repaired. The failure mileage was approximately 90,700.

I was driving my vehicle, heading home on a cold night when the engine light went on, the display said "power reduced to engine", I stopped and the car just shut off. I tried to restart it and it wouldn't turn over. I called for a tow truck and they looked it over the next day and told me that I had dropped all of my oil, with the exception of 1/2 quart, the mechanic then told me that the pcv pipe was plugged and forced a leak and blew causing my car to lose all of it's oil. He is not a GMC dealer so he called the nearest one, mcgrath (formerly bird Chevrolet) in dubuque, iowa and they said that that has happened and there was a recall on them and that the car should be towed there for repair. Once the mechanic at mcgrath, (randy) had taken a look at the car and ran my VIN # he stated that my car would not be covered, even though this same thing is part of a recall for the same make /model/year of my vehicle. He said that I would have to pay out of pocket for the malfunctioning of this part. So far I have had to pay for emergency towing, towing to the dealer, and diagnostic testing, totaling $350. 00 and there's been nothing done yet to my vehicle.

Plugged pcv orifice in intake manifold causing rear main oil seal failure while driving.

Fuel pump failure allowing gasoline into crankcase in large volumes. Rough idle, constant stalling, misfiring, fuel smell recirculating into cabin. Exact issue addressed by gm recall for my exact Terrain and equivalent chevy equinox with 2. 4 ecotec. Was told mine was not covered as it wasn't in correct VIN range though same make, model, year, motor, highly dangerous combustible issue matched. Dealer charged me $700+ for replacement/repair of fuel pump, both O2 sensors, fuel line, oil change to rid gas diluted oil. 2 days, 50 miles later, O2 code engine light comes on, erratic idling begins, power loss then stalls. Removed oil cap to smell and find gasoline mixed back into oil. Between 1/8 - 1/4 quart gasoline in the crankcase after 50 miles of driving! this after "repair" at "certified" chevy dealership; a dangerous manufacturing flaw gm acknowledged was a problem but I was told, " not on yours though, wrong VIN". Thank you for placing my loved ones in danger gm, refusing to fix your own recall, charging me over$700 to worsen the issue and place my family in greater danger.

We have the 2. 4l exotec engine, pcv freezes up, blows out rear main seal, burns excessive oil, bought new, 9/2013? called my local GMC dealer, sells only GMC's since 1954, service dept. Said, they had never heard of the problem, liars! we went to a 2nd GMC dealer, service manager said, VIN is not in recall? he wanted $3100. To do a band aid fix? the best solution for an owner of these pos, is to trade it in, while it's still running, let the gm dealer, take the hit! it's there own fault! won't be buying american next time! sad !!!.

My vehicle, 2010 GMC Terrain, at times would sputter and act like it wants to die at idle, so I took it into the dealership and they found that the high pressure fuel pump was leaking into the crankcase contaminating the oil with fuel. There is currently a recall for this issue, #43180: product emission recall � high pressure fuel pump, reference # n16204318, release date: September 2016. I was told that my vehicle was not part of this recall because it did not include my VIN. I believe that the recall needs to be expanded to cover more vehicles because there are more vehicles that are affected by this issue.

Pcv system froze. . . Air cleaner has water in it// rear main seal pushed out due to excessive crankcase pressure. #14882 special coverage adjustment covers exact issue however my VIN is not included. Requesting my VIN be added to #14882 special adjustment as it applies to my exact make/model/year and issue.

Tl the contact owns a 2010 GMC Terrain. While inspecting the vehicle, the contact noticed oil on the ground underneath the vehicle. The vehicle was towed to joe cooper Chevrolet Cadillac (4920 n automall dr, shawnee, ok 74804) where it was diagnosed that the pcv valve failed. The vehicle was not repaired. The manufacturer was notified and case number: 8-3863678608 was filed. The failure mileage was 149,000.

My car starting sputtering yesterday morning. By lunch, I was a quart low on oil. I added a quart of oil and made it approximately 20 miles when my car started sputtering again, a dashboard light came on saying engine was slowing down and then it died. When I restarted it, the low oil light was on and it said stop engine now. I called tow truck and had it towed to thompson sales in springfield mo - the official GMC dealer. I was called today and told it was the pcv valve that froze up, causing a back up in pressure, causing the rear main seal to blow. I have been doing research on this today, only to find that apparantly there are many GMC Terrains in the 2010-2013 years that have been having the exact same problems. Why is there not a recall on this? when I research it myself, I find numerous complaints of the exact same problem. Apparantly, GMC issued a service bulletin on this exact problem, but there has been no recall. Now, I am looking at having to have a whole new engine put into a car that is only 5 years old.

All the oil leaked out rear of engine, whilst parked at workplace. Crankcase pressure, moisture build up, and/or sludge build up. According to bulletin pip5093a caused by cold temperature, it got down to about 17 degrees here in texas. Mechanic says it will cost $1,800. 00to repair. GMC dealer says it's not a recall and is not covered. Apparently, a lot of the 2. 4l engines in several models have had this same problem happen. Auto has 90,000 miles on it, and I only drive about 10 miles daily. According to gm bulletins this is known to them, as it has occurred numerous times. I believe that gm needs to address this problem and reimburse the owners of these vehicles for these expensive repairs.

While driving home I stopped at a traffic light and noticed a knocking sound in low rpm range. I continued the remaining 1 mile home. When I got home and out of the vehicle I could smell burning oil. I looked under the vehicle and there was a puddle of oil on the ground as well as lots of oil dripping from the vehicle. After having a gm technician diagnose the issue, it was determined that the pcv value had clogged/frozen causing increased pressure in the crankcase and blowing out the rear main oil seal. This is the same problem that was stated in a service bulletin (sb-10057977-8108) that gm has out. My VIN number is not covered with this bulletin for some reason, but this is a common problem with this drivetrain. The service bulletin (sb-10057977-8108) should be expanded to cover all vehicles with the 2. 4 liter 4 cylinder engine. My vehicle is just 2 months out of warranty and gm is only offering to cover 30% of the repair cost. This is a common problem and needs to be resolved.

On Jan 1st it was 3�f out my wife wormed up her Terrain we drove it approximately 12 miles when we started to smell something burning. Next came the engine knocking really bad. We stopped the Terrain and had it towed to the dealership found out the rear main seal blew with such force that the oil covered the muffler. This happened from the pcv being plugged and/or frozen from the cold weather. I recently found a service bulletin for that year make and model that indicates that will happen and there is a special coverage for that. (14882: special coverage adjustment) I also received a letter from GMC about high oil consumption warranty. The Terrain may exhibit engine oil consumption. That is also a part of that 14882:adjustment now to the point I was told that this issue my wife's Terrain would be covered under the 100k/5year power train warranty our Terrain only has 71k miles on it. But the 5year are up. So gm is not taking responsibility for this issue according to both special coverage the 14882: they adjusted to 10 years or 120k miles but they are claiming even though its for that year make and model and engine and that everything that's listed is what happened to our GMC its not for our Terrain. I told them I also had a letter that they sent to us stating the oil consumption that has a adjustment of 7years 6months/120k warranty witch was part of that 14882: special coverage they still will not take responsibility for fixing. I believe we are getting taken advantage of in this situation. They are making us pay for all repairs it may need a new engine in result of the rear seal blowing because it lost all the oil. But we would not know till the repairs start or after all repairs are made and the engine seizes. I also was told from the dealer that if we fix it and drive it down the road there is no guaranty that it will not happen again.

Pcv valve orifice clogged/frozen over. Caused pressure in the crankcase while driving on highway, car died at a stoplight. Removed engine oil dipstick, released pressure to get vehicle to a shop. Mechanic cleaned orifice, drilled orifice to a wider diameter, and cleaned all related engine parts. Gm refuses to reimburse even though same engines with different VIN are covered under TSB 14882. Bill for service attached.

GMC bulletin 14882 special coverage adjustment � plugged pcv orifice in intake manifold this bulletin needs to be extended on my 2013 GMC Terrain. My wife was driving home from work in -11 temps and all of a sudden her car started sputtering and making a whining noise. About a mile up the road her car dash reads " critical oil pressure" and the vehicle turns off. My wife was stuck in the freezing cold for over 40 minutes before a tow truck arrived. The vehicle had less than 58,000 miles on it. I had purchased an extended warranty when I purchased the vehicle. My mechanic found that the main seal and pcv system froze up. He mentioned that the same issue that GMC released under bulletin 14882 had happened to my vehicle. I called gm and they told me that it would not be warrantied as it was out of warranty 1 day prior, they also mentioned the bulletin did not apply to my vehicle because my VIN did not match the product recall. They recommended that I take the vehicle to a gm dealer to inspect (in which they said I would pay for the diagnostic fee). I told gm (customer care) that the vehicle would need a tow as it wont start and unsafe to run. I ended up paying for a tow to a gm dealership and they looked at the vehicle and verified that cost would be $2200 to make the repairs and verified that the issue is the same as bulletin 14882. I have opened up a case with gm customer care but have gotten nowhere with them on why my vehicle is not added to the 14882 bulletin when their mechanics are saying its the same problem. I have gotten a run around from gm customer care team and an unreturned call from management asking to further discuss the specifics on what meets the bulletin 14882 and why vehicle isn't part of the recall. The gm dealership I took my vehicle too even stated they have worked on 4-5 of the same pcv valve freeze in the last couple weeks. Someone plz help!.

On the 2. 4l ecotec engine, the pcv orifice in the intake manifold becomes clogged which causes oil to be pulled into the engine combustion chamber and burned. This causes an excess build up of carbon inside the engine and on the spark plugs which in turn causes the vehicle to idle roughly and stall out while sitting idle, such as at a stop light. Gm has issued a special coverage service bulletin (#: 14882) but only for specific VIN's. It has become known that there are many other vehicles that fall under the year groups stated by gm in their service bulletin, even if it's a VIN that they deem is safe from the problem, but they refuse to recall the vehicles even if they are affected by the known problem. This is a safety issue that causes the vehicle to die while trying to leave from a stationary position once the engine has warmed up, for example passing through an intersection after a red light.

I bought the vehicle with around 86,000 mi - one owner, from dealership. The engine was making a noise within a couple of months. I have to change the oil every month because of the unusual oil burning issue. It died on me three times. The engine would slow down to a stop. I had to turn it off and back on. Later, after a cold day, I had an oil leak. I took it in and the mechanic said there is a problem with the pcv system and the car has had recalls in the past. I took it to the dealership but they said it was not covered. The diagnosis was rear main seal needs replaced. I found a special coverage bulletin from gm online where it said that certain locations/vins are covered because of the crankshaft rear oil seal needs replacement. Mine was diagnosed with this but when I called gm it said my VIN was not on the list. I have had issues with the vehicle since I bought it. Lots of engine noise, very high oil consumption/burn, and difficult to maintain. I would not recommend this vehicle, and I would encourage owners to file for a civil action if they own this type vehicle because all the reviews lead to the same issue. Gm should honor their values by either replacing the parts or recalling these vehicles. I will never purchase a gm vehicle again. The design is great but the engine and system are of very poor quality.

The contact owns a 2012 GMC Terrain. While driving approximately 35 mph, there was an abnormal noise coming from the engine and the vehicle started to decelerate. The contact coasted into a parking lot and noticed an oil odor around the vehicle. The contact noticed that the vehicle was leaking oil all over the parking lot. The vehicle was towed to an independent mechanic where it was diagnosed that the pcv valve was frozen and was not circulating caused by excessive pressure leaking out oil. The intake manifold and cam cover needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 11,000.

2013 Terrain was in motion and stopped on an IL highway in very cold February weather, check engine light came on. Towed to dealership, who states pvc crankcase issue. I investigated and found this issue is listed under bulletin 14882. Dealership and gm corporate line claim that the bulletin number does not apply to my vehicle and thus no special coverage available to cover repairs. Repairs are thousands of dollars for a new engine. Many other car owners have had this issue for years per google. The bulletin recognizes the safety risk, yet there appears to be no full on recall for inclusion of additional affected vehicles. Please help. This is unfair to consumers and hazardous to all wintery drivers. GMC should not be able to claim the bulletin is "VIN specific" when the issue arises due to cold weather--which we all know can occur in many places at any time. Thanks,.
