#4032 of 4070 2003 Yukon XL surge/stalls during wet weather by jskyking Nov 23, 2007 (6:11 pm)
Recently our Yukon XL has begun to surge and stall especially soon after start-up and occurs more often in wet/damp weather. It felt like a transmission slippage at first but we had the trannie inspected and it was ok. Does anyone have any ideas? Thanks in advance. jt jta320comcast.net :
#4033 of 4070 Oil Smell after hard driving. by fixitrod Nov 29, 2007 (2:13 am)
Just purchased 2003 Yukon XLSLT 4WD with 67K, my second... the first was a 2001 XL SLE 2WD purchased new. so this is a step up for me. Really wanted a Denali for the 6liter engine but it came down to the AWD which I did not like the ride feel for some reason. So new to the forum and wanted some opinions on a few issues. 1. Has anyone had an oil smell after driving the truck hard as in mod stop and go and highway traffic. Like when I am late picking up the kids. 2. Anyone willing to share experience with the cold air and/or exhaust kits would be helpful as I want to give this 5.3 some more low end and maybe help the gas milage. I know...I want my cake !

Replying to: isaace (Dec 09, 2005 8:16 pm) My problem is with a 2003 Yukon XL's transmission. It began to whine at ~80,000 miles and progressively got louder. First the dealer played dumb on the issue (my wife took the XL to the dealer who probably assumed they could bumfoozel her) telling her they heard nothing. I took it in myself yesterday morning and told the service manager to get in and ride around the parking lot with me. He did so and recognized the loud whine right away. Unfortunately, my extended warranty ran out on January 1st and now I'm stuck with paying the bill to replace it!   Where is the justice ? My first extended warranty and I find out that it terminated on the beginning of the 5th year, not the date of purchase. Replies to this message: colese (Jun 22, 2009 5:46 pm)

Replying to: rand01 (Dec 07, 2004 3:38 pm) I was curious to how(kit name, cost?) you had your truck lowered and the pros and cons of doing this when using larger wheels/tires. Now for the vent       My 03 YXL SLT plush package 4x4 has an occasional "humming" after going over mod speed bumps as I accelerate and I am wondering if rear end is indicating something. Bought used w/ 67k and although an extremely clean looking truck when I changed to the Gibson freeflow exhaust I was appalled at the condition of the underside of this truck. I did not suspect anything as it drove and stopped OK and the dealer assured me this was a truck they had sold and had just taken back in on trade..."has our pedigree"     When the wheels wre off I checked the brakes and barely got some new pads on before the rotors would have been chewed up. Now it stops like new. The parking brake shoe just disintegrated in my hand.Is it the weight and size of these trucks that make them use more rear brakes atypically than other vehicles?  So much for the vehicle having the dealer pedigree and passing their 127 point inspection. Why do they lie? The previous owner obviously lived on a farm in Georgia because its caked with mud. If intentional water ever was used I'd be surprised. I was just keeping my finger crossed and now the SIHTF. 1. Speedo now dead. Anybody had this happen 2. windows shuddder when you let them down on passenger side. 3. Factory CD player skips on everything you put in it(as I understand it these radios can't be replaced because they are coded to each vehicle[is this true? or can GM code another one]. 4. Homelink won't set to garage door opener. WHo says buying some type of warranty isn't good so hopefully Premier One will take care of these things. I am used to taking care of my vehicles not just for my piece of mind but because of resale and these are machines. I guess it takes all kinds to make the world go round right. Any help appreciated
#4036 of 4070 2002 Yukon Denali XL ignition key won't turn by jeyarda Jan 06, 2008 (8:20 am)
I've had this car for 3 years with no problem. Today I go out to start the car and the ignition key will not turn. I also cannot move the gear shift. The internal lights work fine, the security system is working fine. If I turn on the headlight override I hear a beeping sound (?). I am at a loss as to what happened or what to do. The car worked perfect last night. Any help is much appreciated. I am NOT a car person just a woman in need of some 'simple' car advice. Thanks.

#4039 of 4070 Keyless Entry Problem on 2007 Yukon XL by bigchuckwagon Feb 08, 2008 (3:30 pm)
The Keyless Entry feature on my 2007 Yukon XL has quit working correctly. I've changed to the spare keyfob and made sure that the DIC was programmed to original factory settings. Neither tactic helped. The entrance door must be opened manually......but once inside, the keyfob will actuate the Keyless Entry system (it'll unlock or lock the doors). When I park the Yukon, the Keyfob will lock the doors as I leave......but will fail to unlock the doors if I'm gone for more than a minute or two. In other words, the system fails if I don't use the Keyfob for a minute or two. So long as I actuate the Keyfob every 15-seconds, it'll keep on working. Anybody got ideas?

Replying to: bigchuckwagon (Feb 08, 2008 3:30 pm) A funny thing happened the other day to my 2003 Yukon XL. My speedometer just stopped registering speed.The Homelink won't set and the power seat adjustment are confused...i.e. when I push up the seat goes down. My point...the brains on these trucks have got too much on the mind. I disconnected my battery for a change to an optima red top and to install an intake kit and Gibson exhaust last month. and it hit me that thats when things started going wacky. I disconnected the battery again and allowed the brain to reset itself. Now speedometer works fine. Homelink still won't set so it may be my garage door opener system and the seats I figured out. Truy to disconnect your battery for a few minutes and see what happens. Does anyone know if I can get the factory radio to turn on an aftermarket amp. I want to add a subwoofer and have been told I can use a output control converter(line output converter) but what is going to turn on the amp. I have the Bose system so something must turn that amp om.
#4041 of 4070 Re: Keyless Entry Problem on 2007 Yukon XL [bigchuckwagon] by berkut027 Feb 16, 2008 (3:46 pm)
Replying to: bigchuckwagon (Feb 08, 2008 3:30 pm) I recently had the same problem on mine and found the solution right here on Edmunds.com. See Post 499 in the "GMC Yukon and Yukon Denali Problems" forum, which refers to:   "Tech confirmed failure key fobs using recommendation doc 1861180 put system to sleep removed rcdlr reinstalled fuse retested all OK"   I took this info to my dealer and they repaired it--working fine now. One oddity--the service desk person said that they fixed the problem by replacing the remote keyfob--said there were a bad batch of keyfobs and mine was one of those. I don't think this is the case as my other original keyfob is now working whereas it wasn't before the repair. I think the fix is a software configuration thing on the car itself and has nothing to do with the keyfobs--there may be other problems with certain batches of keyfobs, but it's not the cause of this particular issue.   Good luck.
