GMC Repair: 2005 GMC YUKON XL, gmc yukon xl, 2005 gmc yukon xl

Question
I leased a 2005 yukon xl 3 weeks ago purported to be a "certified optimum used vehicle".  Over the three weeks, the following problems were identified

- squeaky suspension (the noise is now the only thing I hear when I drive!)
- turn signal - occasionally when you hit the left-turn signal, the hazard lights go on
- the air-conditiioning is not working - apparently one of the a/c components was leaking
- when the brakes are engaged at high speeds, there is a lot of pulsating

Should I be concerned with the fact that so many problems seem to be occuring with a vehicle that has been on the road for only a year and a half, and has only 19000 kms on it?

Answer
No I would not be concerned, the squeak noise is probably your rear trailing arms, they have been redesigned and should be replaced under warranty. A/C systems can leak for many reasons, and your rotors need to be turned, again until 36,000 miles it should be covered by your warranty.
