2003 GMC Envoy SLT 4.2 from North America


This is a nice auto with a lot of workmanship issues


The fuel tank has a crack where the filler neck meets the tank. After speaking with the dealership I decided to call GM. I explained my issue with spending $1400 to replace the tank was the fact that the service manager told me that he has seen several of these issues. They are due to the fact that the EPA regulations the fuel tank cannot release pressure and that causes failures to the tank and other parts of the fuel system. This is not an issue that should be considered normal wear and tear. This is a serious issue that if not corrected could kill a lot of people. Undetected, the tank can leak fuel as well as fumes that are highly combustible. The only thing they offered me was a better discount on a new or used car. Long time GM buyer, never again.

I agree 100% / GM is not the car manufacturer they used to be, and they don't stand behind the product anymore.

I will never buy another vehicle from GM again.

No start, Gauges going haywire. Battery is new.

Does anyone have a solution to this problem? There are several people out there with the same symptoms.

2003 GMC Envoy SLT 4.2 straight 6 from North America


Hands down, the best vehicle I've ever owned


Check engine light came on, and the engine idled high after driving for 10 hours straight. Fixed with a computer firmware update at around 30,000 miles.

Stabilizer links on both front and back were replaced early on (around 40,000 miles). They haven't needed attention since.

Axle seal started leaking around 120,000 miles. Relatively easy fix.

General Comments:

As hard as it might be to believe for an American car, this GMC Envoy has been the most reliable vehicle I have ever owned. I have put 120,000 miles on it since I purchased it used three years ago, and have had only a few very minor problems. This stands in stark contrast to the 2001 Subaru Forester I owned previously, which had many EXPENSIVE things go wrong with it.

On this Envoy, the A/C is still ice cold, the electronic 4wd system works perfectly, the very comfortable leather seats have shown no wear, the engine starts and runs absolutely flawlessly every time, and the transmission shifts smooth and strong, even when pulling a stock trailer with four horses totaling around 6000 pounds.

Even the gas mileage isn't so bad... I'm averaging about 19 mpg. Granted, it's not as good as, say, a Mazda Protege, but then again, a Protege can't tow horses.

One extra thing worth noting... in all the time I've been driving this vehicle, I've not needed to replace my brake pads. Most of my driving is highway driving, but even so... 137k miles on the original pads and still going is amazing.

I cannot sing enough praise about the GMC Envoy. Well done, GM, for delivering such an exceptional product.

I'm wondering how long to go on my original spark plugs. I'm hesitant to change them because of horror stories about ruining the threads in the aluminum head. I have over 130,000 miles on the original plugs and it still runs like new. No drop in performance or fuel mileage, and it runs as smooth as new.

Wow. Cmmpared to us it seems you've had a lot of problems with your Envoy. Ours is now 14 years old with well over 150,000 miles. The one and only issue it has ever had was a water pump replacement at about 120,000 miles. That cost me a whopping $49. Ours has never had a tune-up, alignment, shocks or brake pads replaced. I bought new brake pads for it in 2011, but have never installed them because the originals still have less than 25 percent wear on them. The car still runs, drives and looks like brand new. Without a doubt the best vehicle we have ever owned. Since we hate car-based front drive SUVs, we plan to keep this vehicle for many more years.
