Thermostat defective and replaced at 5-6,000 miles. waterpump went at 40,000 miles. parts were replaced by dealer. water pump replaced by my mechanic at my cost. 40,000 miles seems like a low amount for a waterpump. *tr

Speedometer is erratic. started at approximately 65,000 miles. speedometer maxes out, does not work or reads improperly. dealer informed me that the 03 and 04 models have a recall on the stepper motor but the 05 model does not have a recall. the speedometer does not function properly 90% of the time. do not know exactly how fast the vehicle is going. vehicle has approximately 72,000 miles now and the problem still exists. dealer said that a replacement would cost approximately $500 to fix. who can afford this after paying for a $35,000 vehicle. especially after having the steering shaft replaced numerous times, new intake gaskets, catalytic converters, blower motor wires smoked and melted. just a junky truck for the high price. *tr

Engine block heater: heater cord was unwrapped from factory wrap under hood cord was plugged into standard 110 volt temperature was at or around 15 degrees f cord was left plugged in for approximately 2 to 3 hours upon return, cord had a burt smell and had melted around the plug cord was unplugged. cord was tried at a later date, with temp around 0 degrees f cord plug started smoking as soon as plugged in plug was immediately unplugged plug needs to be replaced (has not been done as of this report). *tr

Lifter valve defect resulting in $3700 engine repair. *tr

Continuing problem with loss of acceleration/power but only when it is not raining or when the humidity is below 95%. this results in poor fuel economy. i also witnessed the evap purge solenoid making unusual/loud knocking sounds. been to dealer 6 times for this performance issue. the only code found was for defective evap canister. it ran better but did not fix it. with my scanner, it takes almost a week to finish system testing on the evap circuit where it only takes one warm-up and cool-down to finish testing on all the other circuits. my suspicion is that the evap purge solenoid needs to be replaced. i'm tired of paying $100 diagnostic fees to be told "there's nothing wrong with the truck". i know better since i've driven and worked on my own trucks for more than 20 years now. *tr

Evap emission failure. *tr
