The Under the Hood Show
Dear Motor Medics, I have a 2009 GMC Acadia with 90k miles. We picked it up as a second car for our son to drive to college because of the low miles but soon had problems.
After just a week, the power steering started to whine. We took the car to our dealer where we purchased it and they said that the pump and rack and lines all had to be replaced. This was an expensive repair but with 90K miles and looking like new, we thought it was a good deal.
A week after the power steering repairs, the transmission started to jump when it shifts gears and they said it needs a new transmission. The dealer said they are good cars and this is not normal.
If we have this fixed is there anything else that is common to fail on these?
Jackson in Selah, Washington Dear Jackson, We have seen hundreds of this model in our shop. There are three very common issues we see on these from 2009-13 with 09 being the most common of them all.
Number one is transmission failure that was a known wave plate issue.
Number two was power steering racks and pump, hoses just leak due to age.
Number three, yes, there is another big one, is the timing chains.
Aside from these and once fixed these cars are usually very nice for our customers with little other trouble.
Hopefully you picked it up for a good price.
Take care, The Motor Medics
