2000-2006 GMC Yukon: Stability Traction Control System

Sun, 08 Oct 2023 17:13:17 -0700

What would cause the traction control to kick in when there isn't any wet or icy conditions?

Can I replace a sensor or module?

I do disengage this on my 2006 Yukon (a button on my console allows this), so that I can continue driving without it kicking on.

thank you, Jacqueline

Great! Thanks ABCellars - I have an AutoZone around the corner. I'll get them to check it out - go from there.

Ryan and Mayer, thank you for your input - I'll do some digging in those areas as well!

You all have narrowed down my problem - we'll go from there - let you know what I find out! Have a good one! Jacqueline

2000-2006 GMC Yukon: Why does my brake pedal go to the floor when the engine is running but

Tue, 26 May 2026 06:02:02 -0700

when the engine is running, my brake pedal goes to the floor. when engine is off, I can pump up the brakes somewhat. I have changed the master cylinder and there is no fluid leak. Could the problem be with the power assist boost, or is there something else that could be the issue?

Thu, 20 Feb 2014 04:44:20 -0700

Sometimes when driving my Yukon it starts to hiccup and bog down as if it's trying to stall. Occasionally it might just cough more and not stall. What's going on? I changed the mass air flow sensor; are there any other sensors I should look at?

Tue, 28 Nov 2017 20:37:12 -0700

2005 GMC Yukon 1500 truck runs like it has a few dead cylinders and won't do more than 40mph. When it gets to normal operating temperature it gets worse and quickly dies and doesn't want to crank again until engine has cooled off completely. Just put on new coils, wires, and plugs and the problem is still there please help!

Hi everybody, I just bought a 2005 GMC Yukon Denali w/ BOSE Sound system and sounds amazing for a stock stereo! But can seem to locate the amplifier and subwoofer?

There's a spot in the rear behind the 3rd row seats on the left looking forward from the rear but when I take off the panel there's no subwoofer! Only a jack and OBD2 meter??

I have a 2003 YUKON DENALI XL. My speedometer is stuck on 30 Mph and the gas hand is not moving stuck on a little less than 1/4. I just put $50.00 of gas in the car and it stayed the same It did not move. Also none of the other gauges are moving. I also can’t see the mileage, Reverse, Park, Drive, Neutral lights nothing. Also before this happened I remembered the oil sensor was flashing and I said that can’t be right I just got my oil changed a month ago. Also the washer fluid was flashing saying I needed fluid. I need help thanks.

2000-2006 GMC Yukon: Replacing the bench on a 2004 GMC Yukon XL

Thu, 11 Jan 2024 06:03:04 -0700

Is it possible to exchange the middle bench on a 2004 GMC Yukon XL with the middle bench from a 2007 model? Most of what I see online groups Yukons in the 2000-2006 range, so I'm worried a big change might've happened in 2007. But I can't find any specific reference to switching out the middle benches and I wonder if the bolt placement is compatible.
