Duramax lmm diesel engine had all 8 glow plugs fail one at a time. Replacement glow plugs from GM have a higher voltage rating on them indicating GM was aware these will all fail in time. The original glow plugs voltage rating made the engine start quicker less turnovers at the expense of the owner who had to replace all the original glow plus as thy failed after the warranty period. Few failed during warrant as other reported and most failed months to years after the warranty. In M case they all failed at year 7 of owning the truck and all failed open due to this over voltage that GM corrected in the replacement glow plug. Repair was not cheap and could leave you stranded as the glow plugs fail and are needed to start a cold motor in a cold climate. GM should replace or reimburse owners for these know to fail glow plugs. Original glow plug voltage rating 4.72V, replacement glow plug rating 4.85V. Defective glow plugs causes check engine light to come on and sets PCM codes as well as hard starting and excessive cranking to start. Upon start engine could be very rough as it runs without the cylinder that has the failed glow plugs.

I am disappointed with GM for first time ever. I had a 01 that I got 350,000 miles on it and it had all original parts. Then I buy a 08 and I have oil leaks four wheel drive light on my engine runs rough and my air bag light is on. I don't get it and trust me I just saw a website with the same complaints about what I have when is GM going to say oh [xxx] we have issues with this year maybe we should do something about it. If nothing comes about this I will be going Ford and tell GM to pack sand I have driven GM my whole life and would like to stay but I have owned this truck for only a year and hoping GMC opens there eyes.

Major leaking problem coming from the area of the oil filter.. believe to be something with the oil cooler. This truck only has 40K on it and has never been abused and garage kept all its live... I feel like I have bought a talked vehicle and after paying 50K plus a heavy interest charge over the course of 7 years I feel like this vehicle is going to fail on me while driving and possibly injure me, my family or worst yet some innocent person.. GM needs to get there stuff together and get these same repetitive problems fixed on these trucks because its the same issues over and over and over again dating back to the early 2000's.... you never see this problem in the Toyota or Nissan line ups.... sad but never again will I buy a GM unless they get on the ball and get this stuff fixed.

Cost $7,000 + afm contributed to problem in this model year per service department. Truck never hauled, or plowed with. Regular oil changes and maintenance done on time for entire ownership.
