Lose Power Steering problems of the 2008 GMC Acadia

Car loses power steering intermittently at low speeds, such as in parking lots. The issue only last a few seconds, then returns to normal.

We bought our 2008 GMC Acadia in January 2008. The battery died in July 2008 while vacationing in canada leaving us stranded. After it went dead several more times the dealership replaced it. The air conditioning went out several times in 2010 and we had to pay to have the ac recharged twice since. In July 2013 we had to have the transmission replaced when it stopped shifting into gear. Our warranty had expired in January of that year. The dealership did get gm to pay half but it still cost us almost $2,000. 00. Now it is at the dealership again and we have to replace the entire steering column as it lost power steering at low speeds. We are having it repaired at an estimate of nearly $1,800. 00 more. This vehicle cost about $36,000. 00 in 2008. Since then we have paid thousands of dollars just to keep it on the road and safe. This is a lemon and I would like to see a recall for both the transmission and loss of steering at low speeds. I see that both of these are common problems with this vehicle. I would like to be reimbursed for our expenses.

Problem #1 of 3: during heavy rains, water would leak in through the sun visors on both sides. Took it to the dealership several times. They said the drain tubes from the sunroof were clogged, they blew it out, when that didn't work, they charged me to put it longer tubes, when that didn't work, they said it was because they only replaced the front tubes, not the back. Problem #2 of 3: when driving through water puddles at low speed I lose power steering for a brief time (which is troublesome when turning). Problem #3 of 3: two warning lights for airbags come on everytime I start the vehicle. I can push a button each time to make the written warning go away, but the red light with a picture stays on. Not sure if the airbags would deploy or not.
