Power door locks failed, someone can open the door when the truck is being driven and fall out of the truck, the locks are suppose to engage when the truck is put into drive.

The catalytic converter had strong sulfur smell after the first year. i complained to chevy dealer and was told there was no problem. by year three i complained for the third time again was told no problem the computer didn't show a code. i asked the mechanic to take it for a drive he returned saying the cat was junk it was replaced and i was told only to run top tier gas i did that but after about 8 months it smelled again my truck is just five years old and i need another converter, my power locks have each been replaced three times in second and third year. now i need new airbag sensor and my truck has never been hit . *tr

Forty-five days after purchasing a used 2008 chevy silverado 1500 4x4, the 'service abs and stabilitrak' warning lights appeared on the drivers informational screen. following the manufactures recommendation to re-set the components did not resolve the issues. warning lights appeared every time the vehicle was started. vehicle was returned to dealer where the right-rear wheel sensor was found to be wet, corroded and broken. dealer service advisor (and) technician stated they 'have seen this on many other [same make and model] trucks.' damaged sensor replaced at my expense and old sensor retained by dealer. *tr

The problem has been occurring over several months, it is as follows: the door locks activate to the on position then relock. following that, all electronics shut off, the vehicle lurches, then everything comes back on and you continue on the way. it is especially dangerous at night because all lighting goes off and you are left in the darkness while driving at a high rate of speed. the vehicle has been into the chevrolet dealer an several occasions and they have been unable to find the reason for the problem. the dealer's service manager stated that the vehicle was unsafe and agreed provide me a vehicle, however that was two weeks ago. i have had to purchase another vehicle to drive at night for fear of injuring myself or someone else during one of the episodes. the vehicle is a 2008 chevrolet silverado crew cab with 4 years remaining on the warranty. the episodes occur without warning and at different frequencies, it may happen three or four within an hour or go for a day or two without happening. each time it is a surprise especially if you are traveling 70 miles an hour and at night. *tr

The electric door locks are defective on this year model truck. i had the drivers door lock replaced while the truck was under warranty and at that time the dealer stated that the part was on back order due to the large amount of failure. after the warranty was expired the other three electric door locks have stopped working. i have checked multiple times and have not found a recall for this problem.

Prelude to this event, involving my 2008 chevrolet silverado 1500 (approx 16,200 miles), was the warranty replacement for the failure of all 4 power door lock actuators. the actuators failed one at a time and each time an actuator would fail, the vehicle would shock the driver when touching the metal door while exiting the vehicle. the last actuator was replaced by the dealership on september 18th, 2009. on september 19th, 2009, after engaging my vehicle into reverse gear, the dashboard electrical went dead. gauges went dark and radio began to blink. within 5-10 seconds, smell of burning electrical came into the cab of the vehicle. i popped the hood and my passenger immediately identified a fire near the transmission on the passenger side. the fire was extinguished before engulfing the vehicle. after inspection, we found a shorted out wire near the starter and a broken transmission cooling line. the cause of both anomalies is unknown at this point. vehicle is at the dealership that the vehicle was purchased from. this occurred under "normal" conditions on an improved driving surface. *tr
