Transmission Noise problems of the 2011 Chevrolet Equinox

Sudden internal failure of transmission with around 48,000 miles on vehicle. Vehicle was in motion, started making high-pitched humming noise, wouldn't accelerate, and then stopped moving/driving but stayed turned on.

This is a fwd model with 2. 4l engine. The transmission 3-5-r plate failed at 67,000 miles and the transmission was ruined. When it failed it caused acceleration and speed problems while the vehicle was on a major highway but there was no check engine light initially. The car limped a few miles home stalling out completely once a block from home, it would not go into reverse and had to be towed to the dealer for diagnosis and repairs. I was the original owner of the vehicle it was purchased 06/11/2011. The vehicle also had oil consumption issues and rough idle at this time. The vehicle had its cam shaft actuators replaced in August 2011 after the engine made very loud noises with about 2000 miles on the car. I traded the car in 3 days after the dealership replaced the transmission because I did not trust the car.

I purchased my 2011 chevy Equinox in March 2014 at 40,000 miles. In that time I have only added 16,000. In the last 6 months or so I have had many issues with my vehicle. There was a ticking for a period of time after parking and shutting off the vehicle, a rough/loud running of the engine, inconsistent times of a 'whirring' type sound, and a bucking of the vehicle during accelerating and decelerating so rough that I thought I had been hit from behind a few times. When we inquired about these things from the dealer we purchased from we were told that everything was 'normal' and that's what a chevy sounds like. In August the compressor for the air conditioner went and we thought perhaps that was causing most of the issues and spent quite a lot of money to fix that. It did seem to run a little better for a few weeks. Today I was driving down a 30 mph road and could not accelerate over 20 mph going straight down the road. There was a grinding noise coming from the engine and the check engine light came on. I went to the closest garage as I would not have been able to drive the vehicle to the other end of the next town from where I was. I barely made it to the garage. They hooked it up to a scan and determined that the transmission would need to be replaced. Now I am finding out that I am out of warranty by less than one month. This appears to be a consistent problem in this type of vehicle from what I have now found and something that should not happen with only 56,000 miles on it. I do not drive long distances or even on a daily basis, as the fact that I have only added 16,000 miles in the last 19 months can attest. I am extremely frustrated with the entire situation, especially since I had told the dealership months ago that there was an issue that they didn't bother to look into and conveniently can no longer find record of. Neither the dealer or chevy were helpful.
