Filed Jul 6, 2014 · Engine · 52,000 miles · IN

In wyoming, traveling i90 to hyw 16 mountain pass...7 per cent grade....after two miles engine overheated and had to pull over to let engine cool down...had to take another route to bypass mountain. Googled duramax overheating and found this was a very common problem on the 2004 duramax diesel..design problem prevented adequate air from entering engine...should have been a recall or at least gm should have offered a solution...

I have a 2004 silverado k2500 with a duramax diesel (lly). I bought this truck new in september 2004. I pull a fifth wheel camper. My truck has overheated more than two dozen times, and on some occasions lost power, while pulling the camper up long grades. I reported this problem twice to chevrolet dealers. I have the service orders that clearly describe my overheating problem. Both of these service calls were while the truck was under warranty, but the dealers could not fix the problem. Later when the truck was out of warranty, I found out that general motors recognized the overheating problem and issued a service bulletin #06-06-04-036d that describes my heating problem exactly. This service bulletin was issued prior to either of my complaints about overheating. The cost of implementing service bulletin #06-06-04-036d is approximately $1,300 dollars, so general motors recognizes that this series truck has a significant overheating problem, but apparently they are hiding this fix from the owners until the vehicle is out of warranty. I can give many instances where this overheating problem has caused a safety problem. One time I was pulling the camper east on interstate 40 about a 150 miles west of albuquerque, nm when the truck overheated and lost power. There was no good place to pull over and I was terrified as the heavy traffic had to change lanes and pass me. Another time I was pulling up to the north rim of the grand canyon on a two lane road when the truck overheated, lost power and I had a long line of traffic behind me. It was dangerous as the traffic passed me without good clearance. I could go on and on of similar situations that caused dangerous conditions. There is also a website at www.dieselplace.com that has an entire section devoted to the lly diesel. There are over a thousand posts concerning this overheating problem.

I recently purchased in chevy 2500 hd silverado from an individual and the gauges on the dash are not working properly. Luckily, the person I bought it from was honest enough to let me know this before I test drove the truck. He told he had already spoke to the local chevy dealer and they said it was a common problem and it could be repaired under warranty if the vehicle had under 75,000 miles.the truck had 142,xxx when I got it. I talked to another mechanic and he also verified that this is a common problem with these trucks, as is a hole being eaten up in the transfer case of the 4x4. The repair estimate I got is $350. I think a class action lawsuit should be filed on behalf of all the current owners( or persons that had to pay for this repair) against gm. I am unable to monitor my speed, temp, oil pressure, voltage, fuel or trans temp accurately because of this. If the motor were to burn up due to overheating, I would have no way of knowing it until it was too late. If anyone knows of a lawyer willing to take on a case such as this, I will be more than willing to sign my name due to the fact I am having to pay for the repair to avoid more serious damage to the vehicle or a possible of life if the vehicle were to catch fire from overheating. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

Heater fan wiring harness overheats burns thru at connector between resistor and harness. Several wires in connector -the lead for full power to motor ( high speed setting) is supplied by 40 amp fuse. Wire is approx 16 gage with terminal connections subjected to long duty cycle with high amp load. Wire harness overheated causing fire in vehicle in oct 2005 ( 7,657 miles). Repaired under warranty. Repeat failure in aug 2010 ( 24,615 miles) on 2nd failure dealer stated happens all the time so he had parts dept keep ample supply of resistors and harnesses in inventory. Refused to repair under warranty. 2nd repair done by vehicle owner. Part numbers used in 1st repair by dealership were; connector 88953358 and resistor 89018596. 2nd repair by vehicle owner used delco parts #s - connector del15-81086, and resistor del pt2485. On 2nd repeat failure the new connector appeared more robust in design in area of contact patch between harness and resistor. Terminal interface seemed improved.

Gm pick up trucks have what in my opinion is a safety issue with instrument clusters failing. One can be cruising along and all of a sudden the speedometer goes crazy. Mine registers 120 MPH at all times. It puts one in unknown territory when in heavy traffic not to mention not knowing when one is speeding. Further one does not how much fuel they have or if their vehicle is overheating. Gm sent letters to owners of these vehicles indicating that they would replace the cluster if it went bad before 72000 miles.they know that any or all of the clusters are prone to failure and gm should be required to issue a recall and correct this problem at no cost to the owner.the local gm dealer tells me that it is about a $300. Fix.gm should not be allowed to get away with selling vehicles with such potential safety issues.
