| I have a 2005 gmc envoy. i am having problems with my shift lever; it goes in park and stays there for about three minutes before it releases the key (to be taken out of the ignition). when i start the truck, it will not go into any gear for about three minutes, then i hear a click which then release the shift so it can be moved into another gear. it began about two months ago and has gotten worst over time. once in any gear accept park it can be shifted to another gear without any strain. the consequence of this problem is not being able to get out the vehicle with my key once in park until after the lever cable snaps in place. i have not been able to do much of anything about it thus far due to financial difficulties. *tr | |||

| My 2005 gmc envoy continues to have the same problem over and over. i'm taking it in again today for the 4th time. it loses power going up hills. it's like the engine is stalling, and it has actually cut off on me. the first 2 times they could find nothing wrong. so it didn't get fixed. the 3rd time the check engine light finally came on. they said it was the oxygen sensor, and carbon build up on the fuel solenoid. once again the check engine light is on. this time i had onstar do a diagnostic test. i was informed that there is a power train system malfunction. which is the part of the engine system that provides power to move the vehicle. obviously this has been the problem all along that the dealership can not seem to fix. of course the gas mileage is terrible due to this situation, and with gas prices the way they are it's killing me. *jb | |||

| We purchased our 2005 gmc envoy slt in dec. 2004, which came right off the showroom floor. we had low fuel economy but thought this would get better with more miles. after 30,000 miles our transmission went out without warning. at no time did any internal sensor system detect a problem and we did not notice anything until it was to late. we took it back to dealer and luckily it was covered under warranty for repair. according to mechanic the problem was a small o-ring which was damaged at the factory and that the transmission came from the factory this way. they did rebuild the transmission but now i only have a 12,000 mile warranty on a rebuilt transmission. we feel this is unfair as the transmission was damaged at the factory and was not caused by anything we did. we paid a hefty sum for this suv and now the value has depreciated even more because of this problem. now we feel we have a lemon on our hands and no way to remedy the situation, not to mention the gas we wasted and the time it was in the shop for approx. 2 weeks. we thought we were getting a reliable vehicle!!! *jb | |||

| Tl*the contact owns a 2005 gmc envoy. the contact stated that the engine made a loud knocking noise when driving. while driving uphill, the vehicle dramatically decelerates as if the engine was stalling. the engine and oil lights illuminated on the instrument control panel. she took the vehicle to the dealer for an oil change, but the oil light remained illuminated. she took the vehicle to a local dealer four times and they reprogrammed the p.c. another dealer stated that the engine drags when traveling uphill, which was probably due to the clutch fans. the contact also stated that the air conditioning system does not work. after all four repairs were performed, her vehicle continues to experience the same failures. she contacted the manufacturer and they stated that they would not provide any financial assistance because the extended warranty expired. the speed was unknown. the failure mileage was 3,809 and current mileage was 82,000. | |||
