Gas Recirculation Valve (egr Valve) problems of the 2010 Chevrolet Equinox

While driving on the NJ turnpike southbound from NJ to va my 2010 chevy Equinox suddenly stopped accelerating! after barely avoiding several collisions, the stabilitrac light came on, the service engine light came on and then the reduced engine power notification came on. The vehicle would not accelerate over 30mph, ¿threatened� to stall repeatedly and was vibrating violently. Luckily I was only about an hour into my trip (the temperature outside was below 30 degrees and I had my 4 year old and 3 year old in the car!) and was able to slowly drive the car home and have it towed the next day. I had to replace the throttle body and the intake and exhaust celenoid actuators at a total cost of $644. 05.

Rough idle during cold start of my 2010 chevy Equinox 2. 4l 4 cylinder engine engine idles rough and misses until it warms up when it gets below 40 degrees took car to dealer at 2,000 miles in November, they said everything was fine and to specifications. Said they would keep a eye out for service bulletins on cold starting, never heard from them. Car continue to run rough on cold start. Found on my own a gm service bulletin in Dec. #p00010 on cold start require calibration of engine. Called dealer told them where to find service bulletin they found it and then took the car in . Same problem still exists even after two service visits. The dealer says "they will keep their eye out for another service bulletin on the cold weather starting" as everything is up to specifications on the car. The car still runs rough and misses until it warms up.

My vehicle has similar issues that other consumers have complained about: (1) loss of power on the highway after pressing accelerator pedal down to gain speed. Engine has hesitated and back-fired. (2) excessive oil consumption still remains an issues even though I have brought to the dealer several times. (3) clanging noise in the engine which I have complained about since I purchased the vehicle turned out to be a timing belt issue. Vehicle lost most power and I barely got the vehicle back to my driveway. When I went to start vehicle next day to bring to a repair shop, only the starter was spinning [engine would not turn over as I found out the timing belt disintegrated]. By not knowing there was a special coverage bulletin issued for this problem [extends for 10 years/120,000 miles I believe], my local repair shop brought it to my attention and said although my regular warranty ended, I should bring to dealer. It was replaced for free by dealer due to special coverage in November 2014 [over 4 years of complaining about excessive engine noise]. Broken timing belt created damage inside the engine but dealer covered all damage. After the timing belt was replaced, it sounded like I had a whole new engine as it was so quiet. There is still a small rattling noise during start-up, but goes away after engine runs. (4) gas mileage never has come close to Chevrolet's reported estimates for this vehicle [I get about 20 mpg on flat highways].
