Owner reports
Selected complaints filed with NHTSA by 2005 Chevrolet Silverado owners, lightly cleaned up (personal details are redacted by NHTSA).
Parked truck at outside stall and went indoors. After about 20 minutes I heard noises and went outside. Found the whole truck was engulfed in flames. By the time the fire department arrived 6 minutes later the fire spread to two additional vehicles. The heat melted and consumed everything except the frame. The fire investigator suspects the fire initiated due to electrical failure and generated from either the driver side dash board or left side of engine. The damage was too destructive to pinpoint exact cause.

Truck has 14000 miles, it has constant over heating problems while towing my 8K travel trailer. I have talked with the Chevrolet dealer about it, they told me that they were aware of the problem but at this time have no fix. I call stupid because I heard online that the 06 models have revised cooling systems and a larger turbo charger. My belief is the fix is to much $$ and they will only take care of the few people that tow and have issues. I have notice a lot of information on the net about 04.5 and 05 lly duramax truck that tow over 10000 have this issue but my travel trailer fully loaded only weighs under 9K. The major down side is the trucks inability to maintain the speed limit due to the overheating water temperature and the power loss formed a cooling fan that runs hyperspeeds no stop when towing. …
Truck has 11000 miles, been in the shop 5 times for over heating while towing. GM technician line has a case # on file, and told the technician who relayed the information to myself that they were aware of the problem but at this time have no fix. I call bs because the 06 models have revised cooling systems and a larger turbo charger. My belief is the fix is to much $$ and they will only take care of the few people that tow and have issues. I have notice a lot of information on the net about 04.5 and 05 lly duramax truck that tow over 10000 have this issue. The major down side is the trucks inability to maintain the speed limit due to the 234* plus water temperature and the power loss formed a cooling fan that runs no stop when towing. I have made the same pull with my 2001 Chevrolet duramax truck and have not had issues with impeding traffic flow.

Had to add coolant over a time.....no evidence of a leak on my driveway or any other place. Started truck one morning and heard clicking noise coming from engine. I observed water coming from the muffler. Took vehicle to dealer on April 22, 2014. ( mileage 84241) dealer found blown head gasket and seals, one cracked head and water in oil. Repairs done: complete valve job (replace head gasket, seals & other associated parts), replace broken bolts, replace coolant hoses, radiator & heater hoses and thermostat etc.. Was not advised by service consultant of any recalls or bulletins for 2005 Silverado. This is low mileage for this kind of engine problem. Repair cost: $3683.92 martin Chevrolet *** torrance, calif.
The low coolant light went on. The only way to fill the system is to open the reservoir cap. Unfortunately because the engine had a head gasket failure the cooling system would not depressurize, even when cold. It seems to me that there should be a pressure cap that when the engine overheats it allows the cooling system to depressurize. This closed system is very dangerous especially when someone who is used to filling the overflow tank when the coolant is low. Because the lack of an over flow tank anyone that opens the plastic reservoir could became burned.
Tl* the contact owns a 2005 Chevrolet Silverado. The contact stated the vehicle was abnormally losing coolant every three weeks. The vehicle was taken to a local repair facility where the mechanic was unable to determine the source of the leak. The vehicle was not repaired. Neither the dealer nor the manufacturer was contacted in regards to the failure. The contact was concerned with the possibility of the vehicle overheating as he located numerous complaints online regarding the failure in his year, make and model but no recalls. The failure mileage was 80,000.
Dt*: the contact stated the vehicle stalls at any speed without warning. The vehicle was taken to the dealership several times. The level sensor, fuel injection wiring harness, the direct fuel injection driver, the fuel tank, and the fuel tank module have been replaced. The sender pump assembly was replaced twice. After the last replacement the check engine light illuminated and the dealer could not determine the cause of the problem.
