New Problems Appear
 

My 07 LT2 fall edition has 49,300 miles on it. just recently some problems have occured
1) there is now a rattle coming from the drivers side front end area. Noticeable going over small bumps. Sounds like something falling out.
2) gurgling noise starting up. sounds like coming from in the dash area.
3) after several attempts the headliner rattle came back its over the passenger seat area in back of the sun roof shade. Its been so called fixed several times. but its back annoying.

I do have the gm extended warranty.

any others having any these issues.

1) might be the steering column or the stabilizer links. Both can make a racket and should be covered by your extended warranty.
2) might be something in the heater core... better get that checked out too.
