I have a 16 Denali that has been in the shop a total of 3 weeks and 6 visits. 64K nightmare. For everyone who is having the steering issues GM has once again released a New TSB. This is the 5TH TSB for the 16 2500s now at letter D in relation to the steering issues. the PITMAN arm is now being replaced with a completely redesigned one. GM has released a new part number and my dealership had to order it from Detroit. Wont arrive till end of next week. I have had issues with my truck since Day one and of course GM does everything in there power to avoid the truth and take responsibility for there failure. Dealership even is saying gm is having issues. I ordered a Brand new 17 but am starting to question if there going to make things right. I have spoken with GM over and over for the last 5 months and there just now only going to offer a potential trade assist. No buyback or replace with the 17 i ordered pretty sad if you ask me. was denied auto loan repayment even tho truck has been out of service for a month total. Active BBB case and MD lemon law against GM and they still wont act.
I have had sloppy Steering since purchase took truck back 2 days after i got it and was told it will break in that they see nothing wrong.
At 4000 miles all hell broke loose 4x4 would not return to 4x2
Developed 3-4 inches of slacky steering.
Wheel went severely off center vehicle would go straight at 7-1 could take left turn at center.
Noises in front left of the truck.
Noise when going left to right at park (grinding and bang)
Dealership noted GM did not seat the front left shaft into the hub right and said it was barely even seated at all yet the nut was tightened. They re seated and 4X4 works now.
Steering issue has been failed and failed over and over...
Dealership had truck on alignment rack 8+ times in 6 hours.
Dealership performed over center adjustment on gearbox noticed the lash adjuster was loose and leaking re seated and adjusted .
Truck drove okay for 2 days then back to 3-4 inches of slop.
Dealership called GM and requested Gearbox be ordered.
Gearbox arrived and installed
Truck now Pulls the other direction at highway speed. Have to hold wheel with 2 hands and try not to look like a DUI as it sways back and forth.
10-25-16 Advised and left vehicle at GMC dealership once again. Took video documentation of the truck Thursday(Thanksgiving) and showed management and they parked it and gave me a loaner. Advised me a new TSB has been released once again and now they want the pitman arm discarded and replaced with new design. old design is being trashed. GM dealership acknowledges issues and now has 5 other trucks with issues like mine.
For those going through this Do not give up and put the heat on GM. No reason we as new truck owners who spend a ton of money for a truck to be safe and right should settle for less. Imagine towing a 5th wheel and having 3-4 inches of slop in the wheel its not fun.
