Put new headlights and chrome side mirrors after the picture was taken. 6 months ago, i rebuilt transmission withba transmission specialist garage.. Valve cover gaskets. Replaced. Rear main seal engine crankshaft seal kit, timing sensor replacement, oil pressure sensor replacement, oil pan gasket, and O ring for pump pickup line, all work done by a professional shop. spark plugs and wires done a yr or 2 ago. New tires for the 22s replaced year ago, and they still have plenty of meat. New rear calibers and discs with life time brakes done 1 or two yrs ago. Oxygen sensor done, camshaft position sensor done, valve control solenoid with body & transmission control module replaced, shift kit, banner kit and two motor mounts maybe 3 Replaced. Last summer the AC units was just serviced. Lastly. A torque converter. All work has receipts. As you can tell love went into this denali. Reason im Selling is because it got one issue that i cannot figure out or find anyone that can figure what the problem is. So that's why im selling . it runs, it starts right up and goes but i get. Message on the message board when i gun and turn at the same time, then the transmission goes into safety mode and limits the torque and shifting. And power of the engine. until i stop turn off yukon and turn back on resetting the computer and it runs fine again. I can gun in a straight line and everything runs fine gears change power is there no problems. But when at a stop a gun it and rlturn turn then the computer goes into satfty mode. So thats a little backstory. But it ls a beautiful yukon and iv had it ten years and took very good care or it. If I can't find a reasonable price I might as well keep it cuz I know all that work that I put into it. So pretty much all the little wears and tears have all been fixed aswell as some of the big repares like the tranmisdion, costed over 3k just for tranmissio. other then the engine everthing else that has impotant meaning has been touched. but this is not a engine problem. it's always been a good vehicle up until this problem. As you can tell by all the work that iv did, you kno i cared for this vehicle and i wouldn't of spent all those thousands of dollars if i didnt already know that it was a solid vehicle. that i assumed confidently would have got me through the next 5 or 10 years. But anybody that buys this Yukon and finds that problem gets them a good yukon with almost all the wear and tears fixed already. And it could be so simple too, maybe lose ground lose connection. Its not not major because we w3nt threw all tje major possible issues and spent more then i care to mention. I might keep it still, becuase i kno we touched it all except electrical which was ont got into fully, if i decide to keep thats where i will continue. iv did all the major 3xspensive work, except rebuilding the engine, but there no signs of that kind of problems. Its a clean ride, bose system remote start, remote open back hatch, constant AWD fills like it hugs the ground. And the denali turning is the best turning iv ever experienced in any vehicle, you can U turn in small area and you can turn your steering well with a pinky its so easy. Pedals are adjustable for short people, heat seats, dual climate control in front and back. Bucket seats with the third row seat removable or fold up for more space. Sun roof, 22s rims with 80% ware new tires. Its luxury even Tho it a 07 it still holds it ground in comfortably easily. I still love it. But cant continue spending. Even tho i keep thinking it might just be right around the corner. Whoever buys this yukon and figures it out gets a dam good yukon. And i will be jealous. (Price Negotiable) also important no wrecks.
