2011 GMC Terrain: fuel pump failure

Filed Oct 25, 2023 · Engine, Fuel system · NE

My car wouldn’t start, later found out it was due to timing chain issue which ended up blowing up my engine. I live 40 minutes from work and am consistently driving on the interstate for at least an hour a day. GM said there’s nothing they can do even though there’s been class action lawsuits for the engine. My car has also had oil consumption problems. I bought my car in March of 2022. The engine blew up by November 2022. I barely got my car back in September 2023. After the engine replacement, still wouldn’t turn on, over heated immediately when I did get it back. After paying $7440 for the engine replacement I had to fork over snother $650 to replace the fuel pump control module, and an engine control unit. My car overheated AGAIN just 2 weeks ago!!!!

My gmc terrain 2011 is having trouble accelerating, and I hear a noise from the engine. When I am at a stop light and I try to accelerate, it pulls and doesn't go forward. It's stalking my terrain. I did some research, and I found that this vehicle has a recall #12313d- special coverage adjustment- engine balance chain and fuel pump. I looked up, and it seems this vehicle has 0 unclaimed recalls. So, I'm concern because this vehicle is stalling and not working as it should be. The recall does say, 'if left untreated, could cause the chain to break, leading to engine damaged.

I was driving and my vehicle totally shut down.I had stopped to make a right hand turn. As soon as my turn was complete; it shut down.and would not restart I had to have it towed home.previosly to this it would stall, and I would have to put it in nuetral to restart it. Then next day I had it towed to be seviced thinking it was the fuel pump. Got the call from mechanic telling me the problem is the timing chain broke and has caused serious engine damage...... Piston and valves torn all up..... Obviously a huge problem with this vehicle model. I have read so many complaints about this issue in regards to this model. My terrain only has a little over 100,000 miles on it. I have to pay $5,000. To have a rebuilt motor put in it...... Shame on gmc for putting so many of us customers in danger of being seriously injured. And causing us to pay for this problem; that this vehicle obviously has. I'm sure the mechanic shops love seeing us towing our junk terrains come rolling in. They are making some serious money on rebuilding motors that should never be having these problems.... Come on with recalls please... I can't afford this extra expense.

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.

Vehicle keeps shutting off when driving. I was at stop sign vehicle just shut off I started it back and try to go park it back home it shut off 4 times before it got in my driveway. The truck recently did the so samething two weeks ago and I took it to the dealership and was told they couldn't find anything wrong with it. I just recently got the fuel pump changed, this is when the issue started right after having the fuel pump changed. We went back to the same dealership and had them check the fuel pump but I was told that it was on properly. There are no indicators that pop up, no check engine light. This is very dangerous if on busy highways/interstates.

Purchased my certified 2011 gmc terrain 7/12/2016. After driving a few days noticed car was stalling while accelerating or in stop and go traffic. (1st service) took it in 7/28/2016 to be serviced, was told it was the catalytic converter-vehicle was better, but still hesitates on take off (2nd service) took it in 11/10/2016 received the recall notice about the fuel pump. Finally it seems to be driving better'for a couple of weeks (3rd service) took in 1/16/2017 to be serviced- car completely shut off on busy highway several times during morning rush hour (stop and go traffic), this time engine light came on. Was told something to do with electrical programming communicating with the fuel pump?! As of today car is starting to stall and hesitate again. My certified warranty is up in 3/2017, my fear is next few incidents will not be covered. Keep in mind I have not had this vehicle a year yet. I have a certified lemon. I deserve a refund/upgrade.

There was a recall for my vehicle to replace the high pressure fuel pump. This was replaced and 1 week later the check engine light came on. Taken to dealer. Diagnosed as catalytic converter. The catalytic converter is under a public service extended warranty (10 years, 120,000 miles whichever comes first). Of course I now have 138,000 mile on the vehicle. Gmc will not cover repair costs. This should be a recall not an extended service warranty. The vehicle was moving when the light came on. I first called about replacing the catalytic converter when notified by mail of the extended service warranty, and because the mileage was over 120,000 miles and the light was not on, I was told there was no reason to have it repaired. Depending on what is causing the catalytic converter diagnostic to indicate it has a problem, this could be a serious safety problem. Clearly, gmc issued an extended service warranty to avoid repairing affected vehicles. The 120,000 mile limitation excludes vehicles randomly. This issue could occur at anytime.

I have a 2011 gmc terrain about 62390 miles. When I am accelerating the car jerks. I took it to the dealer they state they could not find nothing wrong. I just got the fuel pump replaced due to a recall. And now a light came on that read AC off due to high engine temp but the temperature gauge showed cold and it never went to normal after being on for 20 mins and to this day is goes to the notch right before normal. Also when the fuel is low the light does not come on. I called the dealership and they stated they have to duplicate the problem to fix it but I cant bring it in until 12/16/2016 because they are booked

The vehicle just stops while driving, this is very dangerous and can cause a major accident. Dealer said the fuel pump was leaking!..for an almost brand new car this was unacceptable!..now it just happened again..the vehicle stops/the engine shuts down while driving!..im taking the vehicle again to the dealership to see what they say...
