    Finally stranded me...

    They didn't have time to test it. They simply diagnosed it was bad (as well as one of my batteries) and changed it out.

    Whoa, that's it! I never thought someone would actually catch it on video!

    Finally stranded me...

    Nope, not like a dying battery. This was the strangest "reluctant" start I've ever witnessed. It literally clicked, turned over EXACTLY ONCE, stopped for about 2-3 seconds flat, then started up normally.

    Finally stranded me...

    Would it be worth investing in those mini power starters I've been reading about? Specifically, the Powermaster torque mini starters. I've read that they are tons better than regular starters. https://www.summitracing.com/search/brand/powermaster/year/2012/make/gmc/model/yukon-xl-1500

    Finally stranded me...

    Update #2: Truck is fixed and I'm about to hit the road. As usual, you all were exactly right. The starter went bad again. I got it towed to the same dealership that performed the job the first time. They paid for towing as well. Here's what the paperwork says: "neutral safety pin in starter...

    Finally stranded me...

    Update: I'M STRANDED RIGHT NOW. In Richmond again. Pulled into hotel parking lot, turn truck off. Go to start it again, it makes a LOUD whirring noise, no crank. I try again. Loud whirring noise, which even continues when I remove the key from the ignition. It finally dies; the truck no longer...

    2012 GMC Yukon Denali XL: oil leak discovered

    Thanks all. After a bunch of research, I discovered and concluded that doing ANYTHING oil related, whether it's replacing the oil pan gasket or replacing the oil cooler lines, is going to be a very difficult job. I pretty much have no choice but to take this to either a shop or a dealer to get...

    2012 GMC Yukon Denali XL: oil leak discovered

    Thanks for the assist. When you say oil cooler lines, did you mean the transmission oil cooler lines, like shown in this video?

    2012 GMC Yukon Denali XL: oil leak discovered

    First, I got stranded last week. Both batteries and starter was changed. See this thread. https://www.tahoeyukonforum.com/threads/finally-stranded-me.129553/ Now, I just discovered that my truck is leaking oil. Can't say it's BAD, but it's concerning. Small puddles underneath the truck in the...

    Finally stranded me...

    Even with all the battery talk, I still think the starter was the primary culprit in stranding me, with the battery being a secondary issue discovered.

    Finally stranded me...

    The only thing I know that leads to credence to rotating the batteries, for me, is that the primary battery has been the one to die....twice now. The first battery came with the truck. The second, I bought brand new, a Duralast AGM. My secondary battery, a plain-jane Duralast, has outlasted both...

    Finally stranded me...

    I added the second battery myself. They are simply wired up in parallel using the stock GM battery kit, so basically acts like one battery. I learned via research last night that I should be rotating (swapping) the batteries, side to side, every 6-9 months. It totally makes sense, since all...

    Finally stranded me...

    Last week, I was out of town with my 2012 Yukon Denali XL. I was in Richmond, and I live in Maryland, so it's a bit of a hike. Anyway, I was going back to the truck, and remote started, and it clicked, like it was getting ready to start...and then after 3-4 seconds *reluctantly* started. This...

    AC blowing "lukecold"; HVAC sticker needed

    Update: took it to the shop. Had them do a simple evac and fill. They said they took half a pound extra out. Fun fact: today was 104 degrees. The ride home from the shop was an hour..... I FROZE MY A** OFF all the way back. The truck's AC was so ice cold, I was sure that I saw some frost...

    AC blowing "lukecold"; HVAC sticker needed

    2012 GMC Yukon Denali XL. Taking it to the shop tomorrow because the AC is "lukecold"; only blows cold when holding engine speed above 2000RPM and going at least 70MPH. Even then, it alternates between blowing cold air and obviously hot air from outside. The problem is, the front sticker under...

    Oil filter seized, destroyed

    Already resolved to use the K&N filters because they have a welded nut on the end.

    Oil filter seized, destroyed

    Sure did. Once I got the old filter off (or what was left of it), verified the threads were fine, and they were. New one screwed on nice and smoothly.

    Oil filter seized, destroyed

    Without turning this into a filter thread, is there a reason I'd go with the longer one? Thanks to you guys I'm definitely switching to K&N for the next go around, not dealing with this mess ever again.

    Oil filter seized, destroyed

    Will the K&N HP-2011 really work? I looked it up on K&N's site and it says that the HP-1017 is the one that works for my truck.

    Oil filter seized, destroyed

    2012 GMC Yukon Denali XL. Always do my own oil changes; 15 minute affair at most. Probably done it close to a hundred times. Never, ever, ever had a problem...until today. For some reason, the oil filter seized and would not come off. I use a Mobil 1, M113A. Has always served me well. I put the...

    Brake stainless steel lines questions

    I have the new Stoptech 950.66002 SS lines installed on my 2012 Denali XL, up front. 1. Is there any detriment if the line is not completely straight? What I mean is, it's not kinked, but it's slightly "twisted", so you can see some warpage. Must have gotten like that when I was installing it...

    Front caliper banjo bolt torque specs?

    I agree. And just to be sure, I checked, double checked, and triple checked my torque wrench. Wasn't the wrench, it was torquing correctly. Tried it on a few other bolts just to make sure. When I was ramping up the torque on the banjo bolt when I reinstalled, I set it to 10, then 15, then 20. It...
