I bought a 2016 2500HD Gas truck after having a 2014 1500. The steering was so sloppy and wandered so bad that I refused to drive it. Dealer had the truck 4x in 3 weeks. Their genius fix after 4 times plus 2 other non service visits and hours of conversations in email, phone and texts - too much air in the tires. Wow! It was never right. The dealer Courtesy Chevrolet in Phoenix Arizona was a nightmare - never buy anything new or used from them. Or go for service - but that's another story for another thread.
Traded it back in - ate some big bucks, and got a 2016 2500HD duramax cc LTZ, my dream truck. ZERO steering issues, wheel was tight and felt as good as my 2014 half ton. Until the 2nd week I had it and the power steering box started leaking terribly- as in puddle on the driveway. Took it to different dealer as the 1st on was horrible- and they had it for a few days.
Thy put me in a compact car loaner and said they couldn't get the part, GM had zero in Stock nationally, and they guessed it was being manufacturered but no ETA. They sealed the leak and gave me the truck back until the part come back in.
So I leave the dealer, guess what? The steering is sloppy. About 2-3 inches I can move the wheel left or right before it is responsive. It wanders and constantly has to be corrected. I move the wheel from 12 to 3 o'clock- the angle indicated on the DIC shows 1degree.
Everyone says "it's impossible" because it's a mechanical system. Until they drive it and they go "oh my I see what you are saying".
Meanwhile I have a $60,000 truck (plus a few thousand of negative equity on the gas truck) I worry about driving to work or towing to go camping this weekend while I wait for a power steering box from GM.
VERY frustrating.
I will add that this truck is spectacular otherwise- I hope they get this issue resolved for me.
