my car is stock actually with new wheels and tires. i went to the alignment shop few days ago with four old wheels wrapped around with tires in my backseat and the trunk. during the alignment, the rear camber was out by far. the display of the rear camper was all red except one green color. he said the car need to get fixed. i didn't do anything.
can the heavy weight(over 200 lbs) on the back portion of the car cause the problem during the alignment? i never felt any problem of drifting to one side on my car.
should i get check again without the heavy weight? can it get fixed?

 

Yes, if your ride height is reduced because of weight, it can increase rear camber.
If it is only on one side, then it might be eligible for the rear camber tsb.

 

There is a TSB out about rear alignment issues due to a badly designed rear upper arm. I had mine replaced and got a free alignment too. This was fdeon with 60000 miles on the car.

 

Check out the FAQ section for the TSB.
