 Truck has been very good overall. One 
problem I have had since new is engine 
idles at 1500 rpm or higher for about 
5 minutes until temp. guage comes up 
to normal operating temp. Took to 
dealer 2-3 times while in warranty and 
they refused to correct the problem! 
Have taken it to independent repair 
facility and they have not been able 
to fix it either. All of them say it 
is sealed up,and no adjustments can be 
made. Maybe true, but correct 
component could be replaced to fix the 
problem. The problem is amplified by 
the fact I live on a mountain and 
coming down it at half throttle can be 
exciting--especially in winter. Hard 
on brakes too.
