Water Pump problems of the 2010 GMC Terrain

I've had issues with this engine since I first leased the car brand new in 2010 and eventually bought it. The service stabilitrak warning light came on at various times, coupled with really rough idle. I didn't think much of it as it was so random I never thought I had a serious engine defect. In July of 2014 I was driving about 60 miles to work one way, and that is when the real trouble began. The service stabilitrak error message would come on several times during those car trips reducing power. I would pull over to the side of the road and turn the engine off, turn it back on, and most times the car resumed normal driving condition. One day in July 2014 the car just died, it wouldn't run. I had it towed to a GMC dealer and they said it was under warranty as I had under 36,000 miles on the vehicle. They replaced transmission, transaxle, tensioner, chain, chain package, gasket, water pump, and balance shaft replacement. They also reprogrammed ecm and performed more diagnostics on service engine soon warning light. From January 2015 thru July 2015 I've had horrible issues with service stabilitrak errors and the engine going into low power mode. It would go away long enough periods that I just didn't get it looked at but now it comes on reducing power every time I drive the car. I really hope this is covered under warranty somehow or able to be fixed through recall. I feel like I got a lemon from the beginning but didn't know until much later. I'm hesitant to take it into a dealer again now after reading so any horror stories about how the dealers are guessing on how to solve the issues and from my own experience of not getting my issues resolved by the dealer. I'm not blaming the dealer, but it seems there is a fundamental design flaw with this engine.

2010 GMC Terrain started making a rattling noise and shaking a stop, like a rough idle, took it to the dealership to get it fixed under warranty, had to replace water pump, blance shaft chain and tensioner replaced intake and exhaust. Camshaft position actuators and bolts replaced high pressure, fuel pump replaced v/c gasket timing chain tensioner and left timing chain guide. That was replaced 09/07/13 in warranty. Now it is 3/09/15 and the same problems have come up again and my car is currently in the shop at the dealership , that means there is a serious problem with this make of engine and it should be recalled before someone gets hurt because of it.

The contact owns a 2010 GMC Terrain. The contact stated that while driving at 65 mph, the contact noticed an abnormal noise and noticed that the timing chain had fractured. The check engine warning light illuminated. In addition, the contact noticed fuel fumes emitting from the vehicle. The vehicle was taken to a dealer who diagnosed that the timing chain, water pump, fuel pump, pistons, spark plugs, gasket and multiple unknown parts needed to be replaced. The vehicle repaired. However, the contact stated that while reversing at a low speed, the vehicle stalled. The contact was able to restart the vehicle. The failure recurred on numerous occasions. The vehicle was taken to a dealer who was unable to diagnose or repair the vehicle. The manufacturer was notified of the failure. The failure mileage was 46,000.

It stalled and the check engine lights came on. This happened again 12/13 replaced exhaust cam solenoid and again in janurary 2014 when they had to replace the camshaft position exhaust actuator. The have also at different times had to replace the high pressure fuel pump, water pump and balance shaft chain, replaced the condenser, evac on the air conditioner on this vehicle and the other 2010 GMC Terrain we own. We do not feel like we should have had to pay for the ac condenser since it happened on both vehicles we own within months of each other but we did. The other 2010 Terrain we own was in the shop in January 2014 because it stalled and it was cam shaft and the throttle body about 2 weeks later we had to take this one in for the cam. The other Terrain has we own has also had the cam worked on several times. This vehicle has also had several recalls for other issues. Something needs to be done about these vehicles because there are so many people having these same problems. Look on edmonds online forum at all the complaints about the 2010 Terrains and the 2010 equinox. Something needs to be done so the owners can get rid of these vehicles before they stall again and somebody hits them and kills them like the six people who died because the 2007 gm cobalt stalled on them while driving. We need the ntsa to help us. They were also going to charge us on the other vehicle almost $900. 00 to fix the cam shaft and throttle body, when the problem had obviously not been fixed one of the other times that GMC dealerships worked on it until I complained to GMC. Then the dealership said we had to pay about $250. 00 because the owner has to pay something when its out of warranty. That vehicle had about 43,000 miles. I don't feel like the owners should have to pay one penny when there is a repeat problem on a vehicle and they can't seem to keep it fixed.
