I am having issues with my brand new 2015 GMC Yukon Denali. I was so excited to get this new car. It had a leak in the back right rear window from the start. They had to replace the entire headliner in the interior. Now I've got a shiver when in idle both in gear and out of gear. It feels like the car needs more gas. I've taken it into the shop 3 times now. The service department, after listening to my complaint and acknowledging the shiver, ultimately states that the car is "operating as designed". I've test driven a 6.2 liter Denali that does not have this issue. They've stone-walled me at GM, essentially saying they can't fix a problem that doesn't exist. Has anyone else had this issue? You would think that a brand new car wouldn't have this issue, and that they could do something to fix a rough idle. I'm beyond frustrated. I'd love to hear if anyone has the same problem.
Hello Thinking about purchasing a new GM truck. I am wondering if anyone is having any problems with their new 1/2 ton trucks. Is GM having any problems with the 6.2 Liter Eco Tec 3 engine or still having some troubles with the new 8L90E Transmission. Other troubles and their solutions would be intresting too. It would be nice to learn in advance what to expect, will it be a wonderful smooth ride. Should I expect a few fixable bumps along the way or am I entering a nightmare ride. Thanks in advance for your input. Success stories are certainly welcomed for a well rounded view.
