Has anyone had a rear compressor issue with a new Yukon XL Denali? My wife and I bought the vehicle at the beginning of October 2018 and within a month the rear compressor began running excessively. We took it into the dealership with bought it from and the service rep heard the noise but was unable to reproduce it later in the day with the technician so they sent us away with the vehicle. The noise became more and more regular so we took it to a dealership near our house and they heard it and acknowledged the problem, this lead them to replacing the rear compressor. The change of the rear compressor didn't do the trick and the excessive running persisted, this is where the frustration really set in. The service technicians were going to run diagnostics and service the vehicle after we brought it in MLK Day. The service department manager interrupted the process and essentially tried to bully my wife into accepting the fact that this is normal behavior for a GMC Denali line vehicle. She left the dealership in tears. I called the service manager in disagreement with 1) his treatment of my wife and 2) disputing the fact this is normal. His response was the discharge the video with a bogus report emphasize the vehicle was in intended working condition. Now the Denali is sitting at another dealership while they try to replicate the issue. It occurs 30-40% of the trips we take in the vehicle and the rear compressor will run anywhere from a few seconds to 20 minutes. Has anyone else had this issue and found a resolution? I'm to the point I'm almost willing to just sell the vehicle back for a loss to be rid of it. -
Hello all I'm new to this read forums my entire life when needing help on a issue someone had back in 99. But anyway I have a 2008 Yukon xl 5.3 bought it a few years back quickly realized there was a issue on top of issue. I got screwed and screwed big time. Truck was sold as 168k miles. It was clean nice good looking truck for 4800 bucks. Turns out won't go over 65. We'll we just said screw it and run it for a while until we got our excursion. So now I've been trying to fix it. I need help I've tried refresh at the dealer it sat there for a entire day in a bay with a tech and they couldn't figure it out. So back to the drawing board. Later on tried to trade it in they pulled the carfax trunk our dude swapped the cluster and it was said the last reported mileage was 278k. Well ******. I want to figure out why it will not surpass 65. It has all the gears. Engine has all the power. No limp mode no codes. I have even pulled the cluster and drove it and that didn't change anything. Please help. Thank you. Derick r.

Last summer I purchased a 2001 Yukon XL with the 5.3L engine, replaced the rear rotor/pads and air filter, then went on a 13,000 mile 8-month road trip starting in Boston, going through Maine, Atlantic Canada, back to Boston for a seasonable job, then to New Mexico via South, back again to Boston through the midwest and finally Florida to help my folks through covid (all safe). The truck now has 191K miles, but the original title indicated the mileage was not accurate (which is how I got it for $1,200 on eBay), so, who knows. The mechanic who did the rear brakes was surprised how little rust was in the undercarriage. I removed the rear seats, added a mattress and three milkcrates for my stuff, installed a cheap aftermarket radio with bluetooth and a rearview mirror camera. Brake and ABS warning lights were skillfully covered with duct tape by the previous owner, I removed the ABS fuse because ABS kicked in without need when breaking at low speeds (dirty sensors?). Over the 13K miles I had 2 oil changes + tire rotation at Wally, and poured Bar’s Leaks into the radiator to stop a slow coolant leak out of the intake manifold. I drove full tanks at different speeds on cruise and averaged: - ~13 MPG city - 20.44 MPG at 55 highway (sorry truckers, thanks for not throwing your pee bottles on my windshield) - 19.53 MPG at 60 highway - 18.81 MPG at 65 highway It’s been a hell of a truck, and now in Florida I have a garage + time, and will do some maintenance. Here is my list, I appreciate any suggestions (or requests): driver side rear caliper/pads/hose (the wheel is a little warmer than the others after driving, and it just started to whistle though pads/rotors are only 13K miles) front rotors and pads, total brake fluid flush check if front hubs need replacement (I occasionally hear a noise when turning left at very low speeds) oil change w/ amazon synthetic + mobil 1 filter trans fluid flush w/ Dexron VI, new filter, and tighten valve body bolts (sometimes tranny thumps from a stop after highway driving, but the fluid is still pink enough) spark plugs and wires (just tested resistance, 7 AC Delco wires are perfect, at about 660 ohms but the 1 shorter Denso wire is at 505 ohms; double platinum AC Delco 41-962s have some gray and orange and could probably go back, but I’ll change just because I went through the trauma of removing them - BTW, three out of the eight plugs have oil in the threads, should I be happy?) fan clutch (not a lot of resistance, and my ac belt “jackhammers” when moving from idle - which according to some of the forums might be due to higher freon temps at idle due to a dying fan clutch) fuel filter clean and seal all grounds both downstream oz sensors (voltage is getting lazy) I’m predicting that between the freed caliper, new plugs/wires, fuel filter, trans fluid and oz sensors I will see some mpg improvement over the next 10K miles, which will hopefully cover the Pacific Southwest, California and Pacific Canada. Thank you all for sharing you knowledge here, I look forward to putting it all into practice. -
Good morning...I wanted to see if anyone else has been shopping for a used GM large SUV? (Tahoe, Yukon, Suburban, Yukon XL) We have been window shopping for a little while now...and I was getting really close to a deal for a used 2019, with less than 30k miles. I started reading some articles that are indicating the supply market is building up on these (probably all vehicles) in whole sale auctions, rental fleets, corporate fleets, lease returns etc...but no where to sell them... the demand has dropped out...some are estimating used car prices will drop 10% and stay lower longer than back in 2008. I was curious what/if any experiences you have had while shopping for a used vehicle? I'm not sure the dealers have really had the wave him them yet...but I'm sure its coming... good or bad experiences? Thanks in advance for the discussion.

Putting together a little Light guide similar to what MotoMedic did for the Silverados. More details to come on this with swaps and some photos (Scroll down a few posts). (Yukon and Yukon XL Only Low, High, fog, license and back-up apply as GMC has more OEM LED handling the others). Some of these may apply to 2014 model year but the bulb size is different like the 2014 Yukons. Tutorial videos (Courtesy of CarCareKiosk and some random dude on YouTube) reflect as: * Chevrolet ** GMC Side Note: OEM HID Color is approximately 4200-4300K. LuciasMaximus and I are playing around with color matching the factory LED DRL. The factory LED DRL appears to be between 5500K-6000K color wise. Suburban*/Tahoe*/Yukon**/Yukon XL**: Low Beam Lights w/HID*,** - D3S Low Beam Lights*,** - H11 (H11-55W) Replace Low Beam Bulb Tutorial * Replace Low Beam Bulb Tutorial ** High Beam Lights*,** - 9005 (HB3) Replace High Beam Bulb Tutorial * Replace High Beam Bulb Tutorial ** Front turn signal* - 7440NA Replace Front Turn Signal Bulb Tutorial * Fog Lights*,** - PSX26W - (12278 / 12278C1 / H28W) Replace Fog Light Bulb Tutorial * Replace Fog Light Bulb Tutorial ** Back-up Lights / Reverse Lights*,** - 921 (921W / W16W) Replace Back-up/Reverse Light Tutorial * Replace Back-up/Reverse Light Tutorial ** License Plate Lights*,** - 194 (194W / 12961) Replace License Plate Bulb Tutorial *, ** (Starts at 0:30) Rear Turn/Stop Lights* - 7440 (7440W) Replace Rear Turn/Stop Bulbs Tutorial * -
New to the forum and thought I would inquire if anyone has some advice in regards to a starting problem I am having. Thank you for reading this. For starters, the SUV is a 2009 GMC Yukon XL SLT 5.3L SFI Flex Fuel (120K miles and oil change light is on, changed oil but have not reset light indicator as I have been playing with starting issue). For the last few weeks it has had a strange intermittent starting issue. When you turn the key to the acc position the battery reads correctly and matches my meter with all electronics working. However, when I would turn the key to the next position (ignition). It would just click. So I would turn it off and then retry with no luck starting. When held in full ignition position it would click and click and then start. as long as you held it in place for a good 5-10 seconds. I checked the battery again and ran tests on it. Brand new battery and no issues. I checked battery cables and grounds with no red flags. I removed the starter relay and jumped 30/87 and confirmed the starter itself has no issue. The starter kicks on and sounds good. Yesterday, I went to start it with a fully charged battery and it would only click. Doors would try and lock and unlock during the process but it would not start. I got out of the vehicle and locked the doors. use the FOB to remote start and the vehicle started with no issues. I got into the SUV and tried the key, and it started right up. Started it a number of times with the parking brake on, parking brake off with no luck in recreating the problems. However, I feel that it's only getting worse with no real answers and no way to recreate the problems or how to solve. Which is why I am here. I have googled quite a bit and read a number of posts here, but no real solution. So I am hoping someone can point me in the correct direction. I love troubleshooting but this is bit annoying. Any help is greatly appreciated.

Hey Guys, wondering which colour combination you think is best for the Suburban/Yukon XLs for exterior and interior? I know colour and taste is subjective but would like to see what everyone has picked! If you can post some pictures of your vehicle that would be awesome. I quite like the iridium metallic or black but still undecided on interior colour. I have a feeling if I go black on black it would feel like I'm driving an airport taxi haha (but it does look really nice though). So post some pictures if you can and why you chose that colour, if not thanks for looking at this thread! Cheers -
