well after 15k miles ive had the following issues with my LBZ: @4500 miles engine failure,also g-80 was 3qts. low,4 bolts and bonding wire missing after new engine installed(2 skid plate bolts and 2 fender mounting bolts)however NO LEAKS of any kind, @8000 miles rear rotors had to be turned(warped)and spare tire would not crank down,@15,000 miles truck gets 19.7 miles/gal.(hand calc. no load)in review engine failure was due to glow plugs melting and falling into two cyls.for my troubles GM gave me a major guard warranty(100,000 miles/72 months) - bumper to bumper and a check for $1000.00 ,and let me make myself clear i love this truck and at the moment all is well,one last thing,that "ticking noise"/type writer sound the ticking pattern has changed,used to be a fast tick,now its slow,it went from every two sec., to every ten sec. or so its not consistant,dealer knows about it,they dont know what to think,time will tell.:)

Sorry to hear your troubles.Mine's been great-only have about 4500 miles--glad you reminded me,I'm going to try the spare tire winch in a few minutes,it's been documented before-you're not alone.

I can't remember when I had a flat tire, but like you Tuney443 I am going to check my spare tire crank this week end. Never heard of that problem before.

Anyway, 11,000 miles and change on my truck since March. The dealer replaced the rubber bumpers on the tail gate and the plastic entry piece on the diver’s side door jamb. Other than that, it has been perfect.

Like I have said before, I like this truck more now than the day I purchased it.

I thought the ticking was documented and is known to exist on all LBZ's. IIRC it has something to do with oil bubbles or some such. GM says its not a problem.

i realize its been discussed before but why is the noise pattern changeing from "tick,tick,tick,tick, to tick...........tick........tick.... tick,im just saying that i notice a differance for the record, now that i think of it,im now running mobil one delvac syn.,not dyno. 15w40.what a nice riding truck,id buy another in a min.:)

OK. Yeah, I don't know. I know my truck went 3000 miles without ticking, but now it ticks. Mine is erratic, sometimes going several seconds without a tick and then 2 or 3 in a row. ????? Maybe it has something to do with how dirty the oil is. ????

After 10k and some change since july the LBZ is still running like a champ. just got back from a trip down south hauling a 69 camero ss with a 572 BB in it. Car was in a 28ft enclosed car hauler. We took it down to TN for a day of drags. Weather around here wasnt so great so we got away this past week. The car is my neighbors that he has restored and fixed up for racing. Tubbed out rear for super wide slicks and full roll cage built. car didnt do to bad. had some timing issue but was still able to pull low 10's. There are some power adders he is thinking about installing but idk.
Anyways. Only issue i have had with the truck since july when i picked it up is the driver and pass seats squeeeeek like crazy. Dealer is actually just ordering me two new seats all together . They are in i just havnt had time to drop the truck off. other than that it great. (knock on wood)

Had my engine replaced at 2400 miles due to the glow plugs. Lost them in 4 cylinders. You got a much better deal, all I got was a 150,000 mile warranty on the engine and anything it breaks. Would have liked the $1,000 and the bumper to bumper. Mine happened in March of this year though. Still love the truck!

Somebody has to buy the trucks made on Monday, I guess your one of the lucky ones.):h

Working on 16,000 trouble free miles on my LBZ. Just regular maintenance schedule too and no engine mods.

yeah but GM better be careful i hear toyota is gonna build a bunch of tundra's on mondays,@ $35.000 bucks a pop i wouldnt yank that monday/friday thing too much.:(

20,000 mi and no issues:ro)

because thats characteristic of the tick "problem", its totally random and doesn't really have a rhythm to it.

14.5k With mine, turbo tube blew off at 3,200 (when I bought it, dealer demo) and that has been it thus far. I LOVE THIS TRUCK!!!

:help:C'mon guys, I need some encouragement regarding my purchase in the next few weeks.
I've read soooo much on this forum and have been truly psyched about getting the 07 LBZ, CC, SB but now I'm second guessing my decision. My TPW I thought was the 23rd and now it's the 30th. Is this an omen? I've read so much about bad wheel bearings and so much cost to own one of these trucks. What gives? It seems as though to get it right you have to spend a few thousand(at least) in mods to make it more reliable, increase MPG and fun/safer to drive. Between shocks, sway bars, oil filtration, fuel filtration, bigger tires, chips, exhaust, blocker and finger and what seems to be something more every day I find myself questioning the purchase.
My current 98 Toyota T100(yeah,I know puny) is gone next Friday. It's definitely not a real work TRUCK but it has suited me fine for my local weekend activities and drives just as well at 106K as it did brand new. Never did anything to it other then regular maintenance. Paid 21K for it new and am selling it for 9K. Now, I am planning on pulling a light travel trailer (5-6K) in the next year and hauling around 2 arm charms but other then that maybe this truck is way more then I need...? Part of me wants to wait for the LMM or the new Toyota which I've heard they are anticipating HP to be anywhere from
350-400 :ro) but it's still not Duramax/Allison combo or maybe it would be if I added all the mods it seems like one should with the D/A.

Okay, someone smack me around and make me see the light! Tell me the I won't have to spend all kinds of xtra $$ to keep this truck afloat.

Not to mention I've sold my wife on the idea of this truck gets the same mileage as my current V6 does but gives a hell of a lot more. I'm hoping the mileage will be similar to one of the better experiences I've read on here.;)

i have often wondered while reading these threads that my truck was going to fall apart blow up and everything else but ive come to the conclusion that there are thousands of these truck out there and people are more likely to talk about their problems than make a post just to say their truck is running fine and theyve had no problems mines only been to the dealer for the steering shaft lube and a door squeek and runs like a champ all the time even though ive floged the hell out it for all 20,000 miles just my $.02

these trucks are perfectly fine stock, there are just some of us who like to improve on everything and make them even better

the same is true for ANY vehicle, there is always things that the consumer can do to improve on it

and as mentioned, this is a forum where people come to discuss problems they are having with their truck. people don't come here to post "hey my truck ran perfect today, no problems at all. this makes the problems appear bigger and more widespread than they really are

You better get back that toy my truck is a real POS too. In less than 10K I've have to change the oils/filters, and rotate the tires. And it’s unsafe to drive if the streets are wet at 35 I can go WOT and it just starts doing donuts. And it really sucks that I get better mileage then my friends new Tundra.

Well, 14,000 and I have only had one issue. Squeaky belt at 1300 miles and after the dealer replaced it, it was fine. Awesome truck, great Mpg and the power is awesome.

buy the duramax/allison, youll be glad you did,best of luck to you.:)

It's true; besides this squeeky belt thing and the glow plug recall this thing is sweet. I've ran the s@#% out of mine for 15,000 miles and love it

Well mine will be 7 months old the 26th of Oct. 49,287 miles , Hard miles 95% towing at above 20,000 Lbs, No problems , I mean not even a plastic part loose , I had one morning when the brakes and steering failed to wake up ,lasted about 5 seconds and never happened again. The truck has pulled 26,000 up a 6% grade at 110* cruise and AC on , passes every truck on the road and has been the best vehicle I have ever had.

tick tick tick....

"The Heart Beat of America!"

12K and no problems.

:exactly: 896 miles and mine just started sounding like a Singer Sewing machine also. I now it is heat expansion sounds from the block, so I am not worried. Well I love the truck and of course my real Singer (in the closet). Both Fine pieces of machinery...

Yeah, now that's what I need to hear! Not that I discount anyone with less mileage but it seems most of the issues tend to happen after the 36K is up...

Same issue on mine... 3,500 miles...

Love the truck!

Hi, Dieseldavesr. I have 10,500 on my truck and not even a tiny issue since I got it back from glow plug surgery at about 3,500. Hope all is well...Carmine

Just turned 10065 this morning. Plug recall and humming noise @55-65mph only probs haven't towed anything heavy yet just a couple old tractors :(..g

I am on my third D/A, '02 lb7, '05lly, '07 lbz. ZERO problems. These are great trucks. But one and don't look back.....................excxept when you just smoked a furd or dodge ):h .

160,000 miles since 12/26/05:ro) . No major problems:D .

my brother has an 06 crewcab sb lbz in shop twice once for rattle in front pass door and armrest and exhaust tick second for egr valve truck has 14000 miles on it also needs new rear tires. too many burn outs

13500 miles no problems, good mileage, tows great, no overheating. I think Howard had something to do with the good build.... built April 14, 2006 Keys in my hand May 1.

I have an 06 lbz with 15,000 miles on it. The motor ended up blowing up because of a loss of oil pressure. It is still in the shop as we speak. Do you guy's have any advice for me, since it has already happened to two other people on this page.

both of the people in this thread had blown engines because of glow plug problems thus causing them to break off and drop into the cylinder. Your issue is different. What do you want us to say? Not every engine is made perfect, as of course they are made by man. There will always be a few in the bunch that have a faulty part that will lead to a failure. Let GM replace your engine.

:exactly: THE BEAUTY OF A NEW TRUCK UNDER WARRANTY....LET UM FIX IT..AND BE SURE TO FIND OUT WHAT CAUSED THE FAILURE...

Duramax/GM track record speaks for itself. This doesn't mean that things won't crop up, Jap vehicles have their issues too, don't fool yourselves.

My roommates dad worked for GM building cars on the assembly line. He said you would be amazed how many things get missed. But they usually get caught before the trucks get to us. He drives a Ford. He said at least he did not know or see how it was built. I have 8000 on my Dmax and it is the most fun thing I have ever owned. I am about to have to replace the rear tires already. That is my only complaint. Oh and the ticking.

At work we just replaced an '02 dmax with 300,000 miles. Engine still strong and all original drivetrain. Only thing done over those miles was the injector replacement(warranty) and a wiring harness for the allison. Great truck and great reliability. Truck could probably run for another 200k miles. That more than anything sold me on my new truck purchase. My new truck has only 2k trouble free miles so far but I love the power and driveability. The trucks are reliable and powerful and I would highly recommend. A previous poster said everyone has there problems and that is true but I feel that the dmax/ally combo is the most reliable/powerful setup going in this class of trucks at this time. I would not hesitate to purchase again and that's coming from a longtime Ford owner prior to the dmax.

10,000 miles and no problems whatsoever. I love this truck, it tows great, runs great, feels great and looks great.

I hated my 03 so much I got a 06 LBZ. I couldn't trade in my 03 because the old lady wouldn't let me... Could you imagine she wanted to drive it.

I just don't understand. BTW, the 03 has over 60k miles, no problems and the 06 has over 8k now with no problems

Ken

7000 trouble free miles on mine.
What an incredible truck!

16k miles in 5 months. No problems. Last trip 3300 miles in 10 days. Hwy @ 75-80mph. 3 days in D.C. traffic. 2 days in Baltimore traffic. N.J. near Philly 2 days. The rest hwy at usually 10mph over interstate speed limits. DIC was reading 17.7 when I pulled back into Merritt Island. This truck is a dream to drive on long trips. XM blasting. 2k rpm @80mph. Morons on the road? I just punch it doing 80 and seconds later I am blasting 90 to 95, get some distance and drop back to 80. Had a chance to use the heated seats! Somebody pinch me I must be dreamin'.

18k no problems except for a dang tag lamp and ofcoarse the ticking noise. pretty sweet thing if you ask me

What they found was a little chunk of metal stuck in the oil pump. They can't figure out where it came from.GM asked the Dealer to ask me how much weight I was pulling; and to ask me if the trailer brakes were working on the trailer. They said when the engine brakes for you there is a chance where if there is a hard enough jolt it some how could of caused something to flake off inside the motor. I told them that I had an 02 d/m and put it through hell and never had opne issue with the truck. Anyway they are sending me a new motor under warranty.

Just turned 12K on my LBZ and love it. Awesome power and love the allison for pulling. ONLY complaint is I had to buy new tires last week, Rears were slick.
For you guys that are having issues from what I have read so far GM has gone beyond just fixing a problem to satisfying the customer which is great to hear. Ex Ford owner and went to 3 different dealers and got the same runaround. Does ford give dealers classes on warranty ducking???? Was fed up and bought a used Z71. Lifted it, ran 35" mud grips and abused the hell out of it. Held up so well I upgraded to the duramax for pulling a bigger camper. Now if I could just get this big *** grin off my face........

Is the ticking sound something that should be looked at? I've noticed it since I bought my truck and it never seemed like it was a problem to me(not that i'm an expert, I'm used to gas engines). Im a little over 5300 on the clock, and it was bought back in july. Changed the oil/filter not long ago and everything looked good. Dirty oil but I've read that was common with diesels.

33000 on mine since sept 2005. new maser cly at 5000 miles, new steering wheel 30000, new driveshaft assembly 28000 miles, and now instrument cluster at 33000 miles, and my cat fell off at 25000 miles.):h i got some torque converter shimmy now when towing.

Just turned over 7000 miles on my '06 LBZ. Got the dreaded engine ticking noise, which is really irritating on a new truck; turbo position sensor(CEL light came on) got replaced at 3800; driver's seat clicking noise and seeping tranny cooler line at the tranny, which it will be going in for those two items next. This is the most comfortable and powerful truck I've owned. Love it. And that's saying a lot since I have a collection of Fords. My biggest problem is I'm putting the miles on way faster than I wanted because it's such a pleasure to drive!:D

Complaints. Hate the front suspension. And there seems to be more turbo lag than I would have thought for this well of an engineered engine. I may be also be mistaking that for transmission downshift, which I don't like. Although I really like the Allison and would not have any other automatic, I have never owned a truck with an automatic and would have opted for a six speed if offered. Which I see no reason why it couldn't be.

Ricoch3T The ticking noise is well known, not a problem. do a search and there will be lots of info on it.

got a flat few days ago same problem rear tire would not crank down.

19,854 completely trouble free miles...but I will check the spare tire crank down (never used it).

Thanks, I usually do but I just joined and didn't think about the ticking until I saw someone mention it in here. Sorry for beeeeing lazy haha. ):h

Hello all,

Well, 16,500 k on mine now and really pretty satisfyed with it. Couple of minor issues. Steering wheel shaft adjustment, one blown speaker :) and a leaky cooling hose for the allison. Had some issues this summer with excessive smoke but corrected that problem by switching gas stations. Power in this thing is lots of fun, have had some thoughts of adding the attitude and Juice but not sure. Mileage is 16.5 in town a 19.5 OTR. Thats with the winter fuel though, summer fuel is much better. Averaged over 20 with heavy loads this summer. Would easily see 600 Miles per tank! Anyone should be happy with that.

LBZFAN

The most mileage that I have seen is 480 per tank. The motor has 15,000 miles.

Now Getting about 500-525 Miles with winter fuel and ULSD showing up.
Not to pick on a business, but I had to quit Fleet-farm Diesel. Truck was smoking all the time, major black smoke even at medium acceleration. Switched stations and problem was gone almost immedietly. Was almost out of fuel one day and had no choice but to fill at Fleet. The problem returned.

13,845 miles and things are great. Just added the juice w/attitude a couple of months ago for the fun factor. I've been getting anywhere from 510 to 560 miles per tank.

8,600 miles on my `06 3500 GMC crew cab dually and no problems with vehicle. Problem has been with what dealer has or not has done with it. They screwed up wiring in my trailer break controller before delivered to me, replaced wheel simulators on rears so slots did not lineup when they retourged rims, have not set oil life monitor/fuel filter monitor when each changed, put wrong service sticker on truck meant for a car with different milage etc., and last not but least the grease marks left on my weather tech floor mats when ever I get truck back from service. I always doubt my service record/bill when I get it back! Otherwise love the truck.....do like the looks of the `07 GMC HD`s.

11,000 miles on mine. It didnt start ticking till I changed the oil. At 8,000 miles I had to get the egr replaced. The dealer was great. Gave me a truck to drive. It only took one day. Also as for the Monday and Friday trucks. I work at the plant and there is absolutely no difference in the trucks. There is to many check points for anything to get to the dealer. I work on the line next to repairs and they are very picky about the trucks going out the door with not defects. Honestly we have to be that way. GM cant afford for a lot of defects with toyota building a full size truck. From what I hear toyota wants a diesel truck also (cat engine). This would put a hurting on us. Anyway I love my truck and hope to put a lot of good miles on it.

I have 14800 miles on mine every thing is troble free..... Except 2 days before thanks giving my ally trans went out without warning I took it to the delar and they are giving me a brand new allison.

On the spare tire where you slide the pipe in at the end sometimes it slides off the part inside of it where it cranks down. i reached under there pushed it back on and it worked. at first i was pissed because i had a flat the valve stem just blew out while it was sitting there. i dont know if that is the problem for some of your spare tires not going down.
