Gas Recirculation Valve (egr Valve) problems of the 2011 Chevrolet Traverse

Engine failed catastrophically on the busy i10 freeway at 50 mph. It was very fortunate that a pile-up did not occur. This could have resulted in injury or death. Dealer diagnosed the problem to a clogged catalytic converter that started to disintegrate and blow abrasive ceramic dust back into the engine. Eventually causing it's complete failure.

June 24, 2017 driving at 70mph on 2 lane highway with outside temperature around 85 degrees and suddenly lost power, speed dropped quickly, engine light came on and stopped car on side of road. Narrowly avoided accident from sudden deceleration. Turned off engine and waited about 15 seconds and restarted engine. Drove ok after that. Had similar loss of power with warning lights of "power reduced" and engine light came on February 2017 in grocery store parking lot. Left engine off for about one hour and then restarted ok but acceleration sluggish. Took car to auto mechanic and they could find nothing wrong.

Takata recall I have a 2011 chevy Traverse ltz with just under 75k miles. I had the throttle body replaced in October 2014 before there was a recall. Today, I got out of class, picked up my children from school and went to the grocery store. This is a 2 mile trip round-trip. I was driving past the kids school straight ahead on city streets doing about 15 mph, just a few blocks from our house, the warning lights began to beep and the dic had several messages. "engine hot a/c off" "engine power is reduced" and "engine overheated idle engine". It became very difficult to handle the truck. The high in chicago today was 60 degrees and I only made the one trip mentioned above. I plan on taking it to the dealer tomorrow but I want to know if this is a problem people are having.

While driving at highway speeds my 2011 chevy Traverse began to overheat. The temperature gauge pegged all the way up to 260 degrees. I checked the coolant tank and could see that it was slightly low but nothing to cause an overheat. I attempted to drive to get to an auto parts store to get coolant. I was able to get the coolant and added the coolant and allowed the car to cool before attempting to start again. After about 30 minutes had passed I started the car again and the temperature gauge was down to 211 degrees. I attempted to drive again and a message came up on my dic, it read engine overheat idle engine, the engine power reduced and I was only able to go about 40mph. I pulled to the side of the road and to no avail in the end had to have my car towed to a repair shop. After $745. 00, the water pump and thermostat had to be replaced. The technician indicated that the water pump had been leaking. I never saw any leaking in my driveway or when I changed the oil.
