I have a 2003 Chevrolet 2500 HD pickup with the 6.6 Duramax diesel engine. At 35, 000 mi the fuel injectors went bad and they were replaced under warrenty. The injectors carry a 7yr 200, 000 mi warrenty. At 81, 000 and 6 yrs, only 46, 000 from the first replacement, the injectors went bad again. I took the vehicle to a dealer and they charged me $190 to inspect and tell me what was wrong. They stated my injectors were bad but not covered under the warrenty??? They stated that cleaning the injectors needed to be done. I paid the $300 to clean the injectors, but the injectors were still bad. The dealer stated that GM would not replace the injectors under warrenty because they were not bad, but the truck still wasn't running correct. I ask if my injectors were bad and they stated yes but not under warrenty?? They said it would cost $5000 to fix, I said NO! I came home and called GM customer care, issues with warrenty, and told them my story. They in there wisdom called the dealer to find out the story and only took there side. They told me that they would not cover my bad injectors because the dealer said so, no second opinion or anything, just no. I still don't understand why they won't replace my injectors but are giving fair warning to everyone else out there that this has to do with $$ and if you are thinking about a new vehicle it would be wise to get away from any GM product as they are sure to go under with the way they treat there customers. I for one am switching to Ford and will never purchase a GM product again.

2003 2500 Duramax Crewcab 4x4 91, 000 miles, and white/gray smoke from exhaust at idle. Dealer told me 5 injectors sticking, and $3000.00 to replace these five, as they are not covered under the extended injector warranty.

Time for a new P/U, and it WILL NOT ever be another GM Product. You see, I also have a 1996 Dodge 2500 ex-cab, 4x4 Diesel, 209, 000 miles and still going strong, despite driving it like I stole it.

Why would anyone buy a GM Duramax if they won't sytand behind their product?

20o5 duramax diesel lly w/(78900) miles injector issues with moisture contamination ???????.

The problem I'm having is the warranty (GM) will not cover injectors due to moisture for a prolonged time that has rusted the hard lines going to the injectors. A Question I had given to the gm costumer assistance people is why do the install an item that would be potential to rusting and no real explanation to that was given but that I have moisture or have had moisture.
I have talked to a diesel fuel quality assurance person for shell oil and was told the caricaturists of diesel would have moisture in it and is inevitable. That is why they put water separators in diesel run products and diesel is a low refined product and still meets quality standards.

R&R of fuel tank steam clean tank replace all hard lines with new, fuel rail's injectors (NEW) will not install re manufactured.

This repair through the dealer is costing me $6700.00
This is to get even for the recall for the earlier models the(GM) had accrued.

The injectors on my 2003 HD failed at 60, 000, they were replaced under warranty. At 96, 000 they have failed again. This time the dealer says I am liable. Apparently the 100, 000 mile power train warranty doesn't cover second time repairs which are only warranted for 12, 000 miles or 12 months.
Has anyone started a group law suit?

2003 Chev Duramax, injectors replaced by Chevrolet at 70, 000 miles, 4 years later (140, 00 miles) they went bad again, seems they are only good for 70, 000 miles. Even though I was told the first replacement set was warrantied for 100, 000 miles it was only for 3 years, $4, 000.00 out of my pocket repaired the problem, they did discount the repair by 20%. This, combined with a new transfer case, $2, 000.00, (pump rub if you are not familure with the problem) has convinced me to not buy another GM truck.

Just to let you all know and thank you. We are looking for a truck. After reading this site and a few others, the Chevy is out. We can deal with any make having "lemons" or a few with certain problems, but we can't deal with a manufacturer who doesn't stand behind their product. Thanks to all of you for the warning.

Chevrolet - Misrepresentation
Saint Louis
United States

I bought a new 2010 Suburban Diamond edition and the marketers called the wheels Chrome so when i went to weber chevrolet the sticker said chrome clad the dealer said they were the same thing just it was an aluminium base clad with chrome then after purchasing the vehicle the wheel started to bubble which was replaced by warranty. Since the wheel was not metal i thought i sould take it back to weber but then sales department said they thought it was really crome clad not plastic clad the part department then looked at the wheel and thought the same thing then tapped the wheel and could tell it was plastic he called some of the other local chevy dealers and same thing no one knew that chrome clad was really plastic clad. I then contacted GM and the idiot on the phone said " Leroy Did you look at the wheel from under the truck?" i then responded" no why would I look at the window sticker and then l0ok at the wheel from under a new truck" now GM will not do anything and i understand why people say these things

Chevrolet - The dealer that sold us our 2001 Chevrolet 3500 truck tried to charge us for problems that didn't exist
2001 Chevrolet 3500
United States

We took our truck in for a few things, including: Battery check, driver's window not going down, license plate light out, check brakes and center console does not open.

The dealer we purchased the truck from did a diagnostic test to check battery {which is not what we wanted}, fixed the window, which was under warranty, somehow we ended up with two bulbs out, checked the brakes and told us that the inner pads needed to be changed and the rotors turned, and the center console was not covered under warranty.

A dealer representative called to let me know how much the bulbs and the brakes were going to be and I chose not to have the brakes done there.

We took our truck to our hometown mechanic and he told us there was absolutely nothing wrong with our brakes.

So, although we did not have to have the brakes done, we feel that we paid the Chevrolet dealer $90.00 to change two bulbs.

I forgot to mention that we bought our truck from this dealer five months ago.

They were also going to check the ABS system and charge us for cleaning the sensors. I was only quoted a price for the ABS cleaning, the brake job and two bulbs.

I've got an 04 and thus far have had no problem until at 151, 000 miles I am getting a cylinder 4 misfire. I'm trying to up the additives and see if it'll go back to normal. Was thinking of having dealer do an ijector cleaning. Any thoughts?

Chevrolet - Bad Product
Chevrolet India

I purchased a Chevrolet Beat 1.2 LT on July 15, 2011. Upon usage of the car I
realized that the same had inherent problems from day one:


There a prominent banging noise coming out from the rear of the car.
The Mileage of the car is very poor 8 kms (approx.) per liter of petrol.


The Senior Sales Manager at the Dealership confirmed that the mileage at 8 km
per litre initially is alright and same will improve to around 12 later. The mileage
of 18 km mentioned in the brochure is never achieved and is only as per test
conditions of ARAI. One of their sales representative mentioned that the resale
value of the car would be Rs. 3.50 Lac, a loss of more than 1.50 Lac in one month
and 700 km!! The dealers kept the car for a long time confirming my opinion that
the car came with inherent defects and my requests of refund have fallen on deaf

Chevrolet - Lemon/ Poorly built vehicle/motor/parts
General Motors
United States

I purchased a 2005 Chevy Equinox in May 2006 with just under 26k miles on it. It was the only used Equinox on the lot that did not come "certified" I should have know right then something was wrong. I also should have wondered why the vehicle was almost five grand less than all other comparable vehicles. I assumed I was just in the right place at the right time and signed on the dotted line. That was my first mistake. The problems began immediately, with the suspension, the sounds, the cooling system, the list goes on and on. The real problem has been the engine. In 2008 with less than 50k miles on it the head gasket blew. GM refused to do anything, because of course my warranty was over and it was not a certified used car with the extended warranty they were not liable. So I paid over two grand and had it repaired. A year later with 80ish thousand miles head gasket blew again, I called GM again, of course to be told there is nothing they can or will do, paid another two grand and had the vehicle repaired again. Yesterday 1/4/2012 while driving down the highway with my three daughters in the car, my car started smoking out the tailpipe so bad I couldn't see anything behind me, my car eventually died in the middle of the highway. I have since learned my head gasket has again blown. I of course called GM, to speak to a foreign person in another country and be told, GM has no recourse and there is no recall involving my VIN. I have read and read and read about the consumer complaints on this vehicle, it is clear I purchased a lemon, quite honestly after everything I have read I'm not sure if the problem is the motor, the coolant, the gaskets or what, but I am sure that this vehicle was manufactured by General Motors Corporation and they refuse to stand behind their product. I have spent over ten thousand dollars on repairing this vehicle and read about hundreds of other people in the same situation with the same vehicle. It is not fair that GM takes no responsibility for the faulty equipment/motor/gaskets what ever it is in this model of vehicle. I have been a loyal GM customer, as family has as well, and I will never purchase another GM product again.

I have a 2007 Chevy 3500 4x4 4dr with a Bradford Built flatbed, use it for hauling a horse trailer and at 30, 000 miles had alot of problems with the "Reduced Power" light coming on (reduced power means 25 mph regardless of where you are) after 6 trips to the dealership no recall was done and according to GM Service Techs an after market air intake would fix the problem...it did but had to pay for it out of my pocket!!!
At 84, 000 miles I started to blow black smoke on acceleration and going up hills, truck has been in the shop 3 times in the past 5 weeks... first time they reprogrammed computer and added updates, 2nd time they changed turbo sensor, this third time they changed EGR valve, still same problem. I went from 12mpg to 6 mpg, truck is going back to the shop for the 4th and last time for new injectors (covered under warranty as I verified with GM Powertrain Warranty this morning) if not fixed this time I will get the Lawyers involved. I understand that things break but I also understand that it is GM responsibility to fix it and fix it correctly. I have been a die hard Chevy guy for 20 years (this is my 4th Chevy truck in the past 20 years) I can also promise you it will be my LAST one.

reading all of these horror chevy stories, has pissed me off, I have a 06 2500 diesel. if I knew back in 07 when I started to replace my fuel filters, I would have researched this issue. GM never said anything about a possible fuel injector problem to me. this last year my truck has 60, 000 miles and my fuel injector valve is failing., It seems so weird you can only get the part from GM for around 1, 000 and 13 hrs of labor to replace a part that only comes from GM. so they want $3, 000 from me to fix my truck, who in their right mind thought GM was looking to rape me and my family out of this much cash to fix a problem they should have fixed or gave us a heads up about the problem! GM sucks, i'll never buy a GM product or recommend a gm truck to anyone! T Munz in Las vegas!!!
