I have a 2008 GMC YUKON SLT 4WD V8. I am having trouble with my fuel gauge. It will say I have 1/2 a tank then I can drive just a few miles and it sais empty. For example I had 123 miles left till empty last night. Today it sais 34 miles and the low fuel light is on. I don't know what to do. My husband and I just bought this car 8 months ago

I've tried everything. Checked the fuel pump, spark plugs, and carburetor. When I try to crank it it tries to turn over but can't quite make it. Any suggestion on what to try would be great. Thank you.

There is a unit under the front dash that is ticking when the air conditioner or air circulation is on. Sometimes it causes just heat to come out. What is that part so I can replace it or has it been recalled?

The lift gate door acuator no longer is working. My rear door does not lock. Has it been recalled? If not, how much is the part to replace?

When I put yukon in gear forward and reverse it makes noise !put in new transfer case and does it still! !only now have no park or reverse! !!!!what could be the problem? HELP

Replaced it and it still codes,, ground issue? something I missed? I assumed bank "B" is closest to the fire wall. Based on research,, but found no actual schematic,,,

If let of the gas at times an re acclerate it will catch a gear. But other then that when first taking off it wont change gears an rpms really high

When taking off its not shifting gears idles real high. There is times it will shift if you let off gas an accelerate gas. An sometimes speedometer goes out of wack

It also stops when I let off accelerator the as I accell again its better.

Battery is good. electric door looks don't work, radio gets hot

now I get a service 4wd message. tryed a switch and shift motor.Also blowing 4wd fuse somtimes.I can hear/ see my old motor move or try to. New motor does nothing, light blinks on old and new switch. Could it be the switch in front diff since I just changed it?

My gauges are not working properly and the service man from GMC said it was due to a wire shortage for the cluster. Does a fule gauge sending unit work along with the cluster? My warranty said they will not cover a cluster but my fule gage does not work along with the other gauges?????

I be driving home from work & it jus starts slowing down. Service stability dhows on the dash. Cant push brake pedal at all. Can turn off & restart & its fine.

The 20amp fuse that powers the turn signals, brakes and back-up lights keeps blowing every time you put the car (1998 GMC Yukon) into to gear. How do you find out the problem and fix it?
