Replying to: tidester (Aug 09, 2006 9:42 pm) On my 2002 XL , the key is stuck in the ignition and the ingition will not start the engine (seems to be a security system issue) nor will it turn backward to the auxiliary/accessory position to come out. Is this a faulty ignition problem or security system disabling the starter and preventing the key from being removed. How is it corrected? Are there any recalls or alerts on this issue? Is it common? How much does it cost be repaired? Thanks, AFF

#64 of 67 4-wheel drive problem by joni0381 Jul 03, 2008 (8:45 pm)
I purchased a 2005 XLT Envoy 2 months ago today. The 1st month the dealership had it 3 out of 4 weeks trying to fix the problems I was having. 1st it was the cluster for the speedometer went out. Twice actually. But that wasn't the main concern. While driving down the road the 4-wheel drive switch will show the vehicle shifting into 4-all wheel from 2HI, and then back to 2HI. You can also feel the vehicle jerk as it is switching over. But, the service department can not seem to find the problem. They have ran the diagnostic test on it several times. I have even tried a different dealership hoping that they could figure out the problem. No one wants to start dumping money into the vehicle to fix the problem since it is still under warranty with the dealership. Has anyone had anything like this happen with theirs????

Replying to: 91ump (Jul 02, 2008 9:08 am) Yes i had this same issue my check engine light came on for my 04 GMC Envoy and it was throwing codes for the cam and crank sensor ,i just cleaned them and they worked fine, you can also purchase them at Oreilly Auto parts(Or some other select Parts Houses) they can get them at a great price ,way better than the Dealership. The camshaft Position sensor (CMP) Is located on the front of head, directly above the belt. Small bolt holds it in, and it is a round sensor.Also the camshaft position sensor code may have set because of the low oil pressure to the variable timing system from low oil in the motor. i would start by first clearing all the codes from the system and see if the light comes back on. if the light does come back on, before replacing the cam sensor you will need to follow a diagnostic repair procedure for the code you get. just because the code says cam sensor does not mean that replacing the sensor will fix the problem. you may have electrical or mechanical problem that is causing the ECM to think there is a problem with the cam sensor.
