I've seen a few people say the injectors on the '03s are not covered over 100,000 and it sounds like they are just as bad as the '01-02's. Why wouldn't they cover the 03's to 200,000? Are the '04 injectors good? I'm looking at getting either an '01-02 Chevy or '03-04 GMC cus those are the front end styles I like best. ;)

03 injectors are covered

I'll back that statement up cuz my injectors just went and they said good till 200k

i took this info from a bulletin on injectors for an 03:

Warranty Information (http://service.gm.com/servlets/BlobShtml?ShtmlFile=1715916&psdid=297&evc=sm#ss5-1715916)

Important: This labor operation listed below is covered by emissions and is not subject to the $100.00 deductible. Dealer’s will need to use the following information when submitting claims on vehicles still covered under that warranty:
2001-2002 Model Year vehicles may be covered by Special Policy Number 04039. Please refer to Special Policy Number 04039 before submitting any warranty claims

nowhere on there does it say the 03 and 04's are covered other then the emissions which is 100k. If a dealership replaces your injectors after the 100k and they do it under warranty gm will come back and make the dealership pay. So if you find a dealer that gives you 200k warranty then do that.


This is taken fom the special policy for an 02 injector failure:

Thanks, that's exactly what I needed to know about the '03s.


So are the '04 injectors good???


-

i have my first 04 in the shop with possibly bad injectors. I rarely see the 03's and this is the first 04. According to gm the 03 and 04 got an updated injector and thats why the special policy is not for them. 01 and 02 got the first design and thats why they got the 200k warranty, but only for high fuel return rates. (leaking)

My 03 has 76k and I haven't had any issues with the motor.

My 03 has 76k and I haven't had any issues with the motor.

a lot of it has to do with maintenance and fuel quality. As long as you are good with swapping the fuel filter and getting great fuel then you won't have any problems....

Too bad you can't tell what gas station has better quality stuff. It'd be nice if you could tell the quality of it somehow. Some people on here change filters a ton and have a secondary filter and they still have problems.

I have an 03 and the injectors were changed by the dealer just before I bought the truck from the PO. I have read where the service manager has made the call to replace, based on the previous year problems, but don't think that would fly to many times.

I have an 03 with 128,000 miles on it. It started puffing blue/white smoke every once in a while. I took it to the dealer today and he said 6 of the 8 injectors were clogged. He said it would be about $4700 to repair. I told him there is a slew of people on forums like this that are having the same problems with the 03's. He called GM and they said they would cover half the cost even though the 03's don't qualify for the special policy replacement. They are also replacing the fuel filter at no charge. He also said if I chose to pay the full price they would call GM and try to get back the entire amount. I decided to pay the "half price", because the other option was a gamble.

Alright I don't know if the GM dealer up here in AK is full of you know what but they are telling me that the 01-03 injectors are only covered till 120,000 or 11 years. Also about the tranny (in a different post) was 3yr 36,000. This info was of yesterday when I called them.

I don't think it'd be any different in Alaska. It's supposed to be '01-'02 7 year/200,000 miles (whichever comes first). '03s and up are only 'till 100,000. Tranny is only covered under the 3 year/36,000.

WickedLB7 - your dealer is confused with the 6.5 diesel injection pump warranty that GM extended. The 6.5TD engines have injector pump problems and GM extended the warranty to 120k/11 years.

Does GM even TEST their diesel products before they make them? I am beginning to wonder. I've been a big Chevy fan because the chassis are nicer and last longer than Fords, but they have yet to produce a diesel without some widespread reliability problems.

Their last two major designs have had some pretty large design flaws - the 6.5s had ridiculously insufficient cooling until 1997 and have had injection pump problems since they went electronic in 1994. The D-max has been plagued with injectors since day 1. How do these problems not show up in the development process?

Too bad you can't tell what gas station has better quality stuff. It'd be nice if you could tell the quality of it somehow. Some people on here change filters a ton and have a secondary filter and they still have problems.
Your best bet is to buy diesel at the big truck stops that are always cycling through fuel. I fill up at a Flying J or Mr. Fuel

My 03' is having issues and I believe its injectors and I have 110,000 miles. They told me it was covered till 120,000 miles and after that its not for certain. Vin code 1 on my truck.

Thanks, I'll keep that in mind.):h

whats so funny

:exactly: I agree! I have 70K on my '03 and no injector issues here. Maintenance is the key!!!!!

Sorry...nothing. Just nodding and smiling. Thanks for the input. ;)

Knock on wood.

Maintenance is the key to longevety with everything! my truck has never seen 5k without a fuel filter change, and has never seen over 3k without oil and filter change. 102.000k on truck with no issues.I use synthetic oil also in hope's of a 300.000k mile engine. Keep up the maintenance men!

Wow, you have driven 102,000k ? I am confused. That would be 102,000 kilometers? It is certainly not 102,000 thousand miles. That would be 102 million miles! Or did you mean 102,000 miles?):h

Seriously, when it comes to these injector problems being reported, knock on wood, I have about 67,000 miles mostly highway and interstate, no performance enhancement chips, and I have a Nicktane 2 micron pre-filter kit that went on the truck at about 15,000 miles, and I change that filter, along with the under hood factory filter, annually. Oil change interval is when the DIC says 35% life remaining. Almost all my fuel purchases are from the same high volume station.

I often wonder about the correlation of fuel injector problems and aftermarket performance enhancement chips that modify the operation of the injectors.

I have 60,000+ on mine running edge set at level 3 with no problems so far. 98% of the time it set without moving from stage 3.

sorry i forgot total milage on my truck is 93,450...maybe they are using it to soon and are not waiting for the engine break in period.

K1xv; Sorry if i was not clear about my milege, it has 102 thousand miles on it.

Well, my 2003 has 106,000 miles and is at the dealer right now with two bad injectors. THe dealer, here in MN won't even talk about warrantying them. 'Pulled up the original warranty on the truck and showed me engine warranty to 100K. $3500 to replace the two bad ones or $6000 to replace all 8. I made a call to GM and they said, no 200,000 mile warranty on the 2003 's, only the '01 and '02, but offered to call the dealer to "provide some financial assistance." I'm waiting to hear back on what exactly that means.

My 2003 had the injectors replaced at 47,000 miles!! I will never pay $6000 to get the injectors replaced, you can get an engine for that much. lison what dealer did you take your truck to? Keep us posted

I had it at Iten Chev. in Brooklyn Center because I had read on this site they have great diesel mechanics. I had bought the truck from Gateway Chev. in Fargo, N.D. used with 80K a year ago. The guy from Chev. customer service called Iten and asked them if they would discount and the dealer told Chev. they would give 10% off on parts, but why should the dealership pay for a persistent problem that Chev. should be responsible for. I picked it back up this afternoon for $119 and still two bad injectors, #5 and 8. I did get the fuel filter replaced from the recall tho. The one with 10 micron filtration so as not to damage the injectors! I had already put on a Nictane as soon as I bought it. The Chev. rep is supposed to call me back tomorrow. We'll see what he has to say. Right now, I'm hoping for an offer to split the cost.

I hope someone at GM reads this.........though I haven't Had anything major problems with my truck......under a 1000.00 in repairs.......but from what I see here... the worst is still to come......how can GM expect its customers to trust them.....we spent our hard earned money...thinking we will have a few years of problem free driving.......put this in not the case......Im sorry but I spent alot of money.......and all I think I got..... was a lemon

I purchased my '03 in April '03 new. It's now in for injectors (2 bad, all 8 getting replaced). I'm guessing that I got some of the bad '01/'02 injectors. If I had to pay $6k to get them fixed, I'd scrap the truck--that's more than the engine cost in the first place!

Yeah well what happens when the injectors go in the next motor? If someone actually pays out of the pocket to have them replaced I've heard that they are LIFETIME garaunteed.....a little easier to put out the g's if you have it but still sucks bad. Bosh should be held responsible just as much as GM. Bosh needs to figure their crap out...otherwise GM should look for other suppliers of injectors.

I know I asked before why you never hear of injectors going bad in gas motors...the answer was that they have a lot more pressure going through them......Ok makes sense, but why don't semi-trucks or heavy equipment have these problems?

Most heavy equipment engines aren't required to be as eco-friendly as passenger vehicles. They can use mechanical injectors, or injectors that aren't as precise at fuel metering, thus they last longer. They do fail, just not as chronic as these. Also, engines like caterpillar, cummins, massey ferguson, john deere, etc... have been making some of the same engines for 50 years. Their kinks were worked out a looooooong time ago. Let's not forget the 6.6 liter duramax is only 5 or 6 years old. And even now, we aren't hearing of many injector issues past the 2004 models.

Well, just had all 8 injectors replaced in my 03 with 106,000 miles and paid $4000 out of pocket. I've made four calls to Chev. customer service. They promised to call me back the nex day after the first call and never have. The first dealer I went to quoted $6K for the job, the second $4K, so I took it.
When I asked about the warranty on the new ones, I was told that until Jan 1, 06 they were lifetime. In Jan. Chev changed it to 12,000 miles or one year on all replaced injectors! Unbelievable. Has anyone else heard this?

I had my injectors replaced on my 03 with 128,000 miles. My warranty is 1 year or 12000 miles as well. They wanted to charge me $4700 but I told the dealer that a bunch of people on forums like this were having problems with the 03's so they called GM and they said they would pay for half the cost. My total bill was less than half because of cheaper labor rates for warranty work. It was $2,083 including tax and an a oil change. They said I could have paid the $4700 and then tried to get the entire amount back from GM but that was a gamble. So I took the half. Sounds like it was a good decision.

Sounds like I'm gonna stick to an '01-'02 Chevy then. At least I still have a few years of warranty that way. I'd hit the 7 year mark before the 200,000.

My 03 with 10800 has bad injectors now also. Ive been to 2 dealers. waranty wont cover the $5000 replacement cost. ($#@!&!!!!) ouch!!! $3000 is the cost of the injectors them selves. :confused: Censored Gripes, Bosh has a monopoly here. cheapest remans I have found are $250 each. Ironicly the part #'s for injectors for 01-03 are the same. What is up with that!! My company runs a dodge cummings and 2 ford power strokes. all well over 100000 and no problems. Tired of making excuses for GM.
P.S all trucks have fuled from the same station. fuel filter changed every 5000 religiously.

:exactly: I agree! I have 70K on my '03 and no injector issues here. Maintenance is the key!!!!!

Maintenance, Shmaintenance:rant: . I always used a fuel additive (stanadyne) and have pre-oem fuel filtration--both fuel filters changed out at regular intervals. Oil also changed every10k or sooner. lost my injectors @48k. Within the last 8 weeks I've had FPR, injectors, fuel filter housing all replaced, a coolent leak fixed, and now of all things, the electronic rearview mirror is shorting out (goes dark in the middle of the day, then flashes back to clear!). At this point I'd be happy if the truck lasted just 5 years past the payments!

I have an 03 and was told that if the 8th digit of the VIN was a 1, then it had the same engine/injectors as the 01 and 02 models. Mid year they supposedly started using newer style injectors.

We have a 2004 at work and the vin check noted the injectors had been replaced under warranty so there is another 04 failure
