    Thinking of a newer SUV...a little help please?

    I agree w/ above but in my own search did 2012-2014. There are a lot fewer 2014's for sale, they are a harder find. As Phil said I would not look at anything above SC personally. I am over the moon with my recent purchase a 2013 LTZ suburban Florida 1 owner w/ service records. Paid 19K .Car is...

    Dash Cam : Your Install and Lessons Learned

    I live in Florida and any camera that has a battery can't be considered. You need models with capacitors. Some say super capacitors. Batteries won't last and will bulge open. That new Viofo is a capacitor camera I believe.

    ALC, AutoLevel, Autoride, Magnaride, Premium Ride

    Don't waste your time disconnecting it....it will still ride very tight. The spring rate is just high. As posted above Fox is a fantastic shock and properly picked can have a great ride, if you also change the springs. Fox makes the shocks for the Raptor. But they also have the correct spring...

    2020 Yukon Denali..Fuel miles per gallon

    Your not broken in yet. My best mileage started after 5000 miles. I had a 2017 Denali which had the 8 speed and routinely got 21-23 mpg at 80 mph on the highway. I have gotten higher but it took some effort. If your all stock with tires and suspensions, check your air pressures, premium fuel...

    ALC, AutoLevel, Autoride, Magnaride, Premium Ride

    Thats the way they are and designed. I had a 2015 Denali XL and a 2017 Denali XL. The '15 was a dump truck, the '17 was better but just NOT a nice ride. Dealer explained to me they were designed that way to lower their rollover rate. Well I can agree that it was fast as hell and handled turns...

    2011 Yukon..Transmission shot... worth replacing?

    I understand why people do this lamenting because your adding value to something that you feel isn't worth that much. BUT add 3-4 NEW car payments up. Then imagine having to continue that car payment for 60-72 months! So in other words it is worth it to YOU to fix this truck and NOT have that...

    Drive Belt Tensioner Noisy. Replace Whole Unit or Just Pulley?

    I just did mine not long ago. It's a pretty easy straight forward job. You know that AC belt will go on the hottest day of the year right?? LOL I did the tensioner pulley, pulley, serp and AC belt, less than an hour. Youtube is your friend if you have the stretch AC belt. Zip tie or tool takes 5...

    2013 Tahoe..Preventive vs Reactive

    My brother just sent me an email asking the same thing...he is at 105K...: My detailed response: Differential fluid is very 30-50K depending on use. Amsoil sever gear fluid only. Order online-- you need 2.5 quarts buy 3. Transmission is 50K for sever use (Florida is considered sever due to...

    2012 Tahoe-Lights get brighter and dimmer

    My 2013 does this also. 100% stock, in near perfect stock condition. Original alternator. I had already checked all my grounds and they are perfect. This truck spent its entire life in Florida and has no corrosion at all. I notice it when the AC compressor kicks on or the fans. There have been...

    Doors locked---Truck running?? How did this happen???

    I agree, she's always guilty of some chaos! LOL But when I did it today, the drivers door pops. ??

    Doors locked---Truck running?? How did this happen???

    Thanks Guys! I'll have to see if the auto lock is set? Yes, you can lock the doors with the key in and or running but only if the doors are closed, I do this also when waiting on my wife. But if the door is open and you hit the lock button with it running it automatically opens the driver door...

    Doors locked---Truck running?? How did this happen???

    Hey guys, need your input and expertise as to how NOT to do this again. I have a 2013 Suburban LTZ. This is exactly how it transpired. I drove my aging mom to the Dr. I stop the truck, put it in park to let her out by the door. When you put it in park all the doors open. I open the rear hatch...

    2013 Yukon..Strange screaming noise/smoke from passenger side of engine bay

    As several have said, it really seems to be the AC compressor. The location of the smoke comes from that exact spot too. I have a 2013 and it is a stretch belt. I used a brand new razor and it sliced right off. It is behind the serp belt. Gates makes the tool for about 7 dollars to install and...

    Looking To Upgrade

    What exactly is your point on what the truck cost? It was bought in 2017 below sticker, no incentives as in today? Yes I KNOW they have huge issues. I had them. I have been a GM truck owner for 30 years, and this last generation is a disaster. The 2015 Denali was in warranty over 14 times...

    Looking To Upgrade

    Really do your research, not just here. They have issues. Not small ones either. (radiator, ac condenser, Torque converter, transmission, vibrations, booming in cabin) Really unacceptable stuff for a new vehicle! These trucks were over 70K ! I have owned 4 of the new trucks and had many issues...

    Any1 keep their ride as a spare vehicle?

    Our 2013 suburban is a second vehicle to myself or the wife as we both have other primary vehicles. We had a 2017 Denali XL and hated the new platform. Also the value wasn't there. I traded into a S550 and wife stayed in here VW Jetta. Within 6 months we realized we really needed a truck for...

    Terrible fuel mileage

    These rigs are heavy. It doesn't take much to affect the mileage in a negative way. When I first bought my 2013 Suburban it was mechanically pretty well taken care of but was due for a lot of service due to mileage. It had 94K. I did a lot in the first month and gained about 2 mpg. I couldn't...

    Water gurgling noise under passenger side dash

    I would check your drain hose from the AC evaporator. As stated above check the passenger floor. Also are you using the heat? Could be in the heater core. If its gurgling I'd check coolant level. It could be gelled up also. Meaning clogging and fluid is having hard time getting through the core.

    Debating

    I can tell you from experience, I would NOT do it. I have been a GM guy my whole life. I learned a very expensive lesson, that newer is not always better. Money was not the issue but in hindsight it is all wasted money for me. I had bought a new 2007 GMC 5.3 4 speed. Best truck I owned. Sold it...

    Belts and pulleys/tensioner

    Its very easy. I just bought a 2013 Suburban LTZ w/ 94K. I just did the tensioners, pulley, and the belts. The AC belt is easy but takes a little effort. There are several videos on youtube regarding. Some guys show how you can use zip ties, and others with the special tool. I bought the tool...

    2012 through 2014 Yukon Denalis.

    While I agree, many issues with these motors are from poor maintenance or none at all, the second is poor oil quality as in cheap oil. I run Mobil 1 in all my cars. I also do oil analysis on each vehicle. Some cars beat up the oil worse than others. But on my Gm LS motors 5000 miles is my target...

    My big girl saved my life

    Glad your OK. Thanks for posting. She did well! This is why we drive them, and put up with the fuel mileage. At the end of the day, you don't get to pick your accident...but you do get to pick what you will be in when it happens!! You will be sore this week, take it easy and check in with your...

    2010 Escalade Or Keep My 2015 Tahoe LTZ

    Downgrade? I have had 4 trucks in the new generation that last being a 2017 Yukon XL Denali that I bought brand new. The new trucks suck. Quality is terrible, and I have had issues with everyone of them. I am a maintenance freak and really take care of my vehicles. I could go on and on with a...
