Do you have the Autoride Z55 or Z95 (not likely don’t due to year) or more specifically front electronic controlled shocks? Assume you do with an LTZ. If not, disregard this post (sorry). If you do have Z55/95, bite the bullet and buy new GM OEM struts and remake the assembly like mentioned...
Don’t’ think this is a variable but your new front struts would need another alignment if that came after. And with your year, I bet you had a hard time finding OEM parts and I’ve had experience with poor front struts from Duralast (only like-OEM for me). I had 3 failures on new Duralast struts...
Echo folks here; primarily sounds like bad battery, failing alternator and/or grounding issue. I know that sounds simple but those three things are all involved in your scenarios. That being said, with a new battery, and checked alternator, replacing the water pump is the main focus IMO as it...
The errors your getting are misleading as your truck will go into “limp mode” and/or throw that stablitrak message for many reasons like suspension errors or as I suspect a dirty throttle body. I’d follow the earlier advice and clean the TB and use MAF cleaner to clean the MAF. Don’t rid of the...
I’m surprised no one has brought up checking the suspension first at 170K miles. Or I missed it. The ESC(m) will shut down the system into limp mode, which is what this sounds like. Crazy dumb feature and dangerous as it happened to me driving down the road. I have the 2013 Yukon xl Denali...
I’ve set my Yukon XL up with dual batteries and Redarc isolator and been happy for years. They work as a single battery TBH. The main battery runs things as normal, pivots to spare when volts drop to certain level. The Alternator will charge both batteries back up starting with main, then hits...
If you’ve exhausted factory options, here’s something that would work. This is a costly option but I have an older Yukon Denali XL that has 3G service (OnStar therefore stopped) so I upgraded the remote start to the Compustar Drone mobile App. Of course, you can start it from anywhere via phone...
