I cannot stress to you about how much my 05 Armada has been giving me problems. I have to take it to the dealer every couple of weeks to get something fixed. From the A/C to the automatic tailgate. The A/C wouldn't give out cold air. It takes about 15- 20 minutes for it to get going. The steering wheel vibrates when you go 55 mph or more. The DVD system would not play the DVDs. The front headlights got water stuck inside of them because they were not installed correctly. The CD player would not eject my CDs. I went to the grocery store and I had a whole bunch of foods for Thanksgiving and the tailgate would not open. You could not manually open it or even open it with the remote.
