Talk about problems with your Duramax - as well as the older 6.2 and 6.5 diesels - here!

I didn't know any problems with the Duramax existed The original LB7's test mule of 1,000,000 miles and GM, said good enough for us and they shut the Duramax truck's engine off. They then took it back to the lab and the engine showed only minimal wear and one guy said she'd probably do another million. "So, the story goes"

#3 of 359 GM bulletin for Duramax by grabowsky

Oct 27, 2006 (2:47 pm)

I took my 2006 Sierra 2500HD in today for an oil change and to have them check out a "ticking noise" coming from the engine bay. The dealer service gave me a technical bulletin #02-06-01-022E dated 1/12/06. The gist of it is they all do that,some worse than others. Supposedly the condition doesn't effect durability or reliability. We'll see....
Anyone else have this ticking?I love this truck and hope to have a long relationship with it. You know what I mean!

#4 of 359 02 injectors by gandalf2

Have 02 Duramax. In 04 with 112,000 had injector failure, all 8 replace under extended warranty. Now at 220,000, have had 4 fail, dealer says that for 4 injectors and a fuel filter - cost $2700!!! Some people say that GM will warranty the injectors, dealer says "no way". Seems excessive to me and just not right. Any help or proof if GM did honor a second set?

I have a ticking noise in my new 2007 duramax. Bought it in September and has 4200 on it now. I took it to the dealer they didn't know anything the Rep came by didn't know anything. They took the cross arm off to pull the lower oil pan off, then removed the transmission and fly wheel to get to the upper oil pan and adjusted the oilers. Spent a total of 14 days in and out of shop longest lasting 10 days. I got a call today saying the same thing. If your statement is true why did they tear the lower end of my motor apart. Looks like used vehicle now from underniegth.

Apparently your dealer didn't know about or care to find the tech bulletin. They probably figuered they could get some warrenty money out of it. If I were in your place I'd go to a different dealer in the future.

My 03 silverado has had injector failure 4 times. Starting at 106000 miles. You will most likely have multiple failures. You will need to replace all 8 injectors.Cost is about 3900.00 per failure. Call Justin at GM 1-866-790-5700 ext. 21605. TELL HIM SHERRY WEBSTER REFERED YOU TO HIM.i HAVE FOUND 46 OTHER TRUCKS LIKE OURS WITH INJECTOR FAILURE. LET ME KNOW WHAT HE TELLS YOU. JYSYWEBAOL.COM. GOOD LUCK.

#9 of 359 California Gas by evergreen

Several months ago I was riding with a friend in his Chev Duramax truck. I think it is several years old and he mentioned the only problem he has had was with the injectors which needed to be replaced. Even though the truck was out of warranty, GM did the work at no expense to my friend. I live in Oregon and apparently the problem for my friend was traveling a lot in California. The GM mechanic told him the problem had to do with the gasoline additives used in California. I guess the injectors where replaced by a type that can deal with the additives. Just passing this on, for what it's worth.

#10 of 359 Duramax 2001 Starting Problems by redrig

Jan 18, 2007 (10:59 am)

Intermittent failure to start - engine turns over, ignites, dies, then won't restart. Replaced fuel system heater, seemed to fix problem, then happened again, for 3 time. Service shop placed on computer - no errors shown & after towed to shop, started without further repair & continues to start.
 
Each failure happened when truck was parked in same spot - slightly downhill with wheels turned to right. Also, temperature had dropped significantly overnight.
 
Would appreciate any insight available since repair service can't do much until problem recurrs.
