2003 GMC Envoy XL SLT from North America - Comments

14th Mar 2008, 14:21

I just took our 2003 GMC Envoy XL to my mechanic due to a strong gas odor! Yes, the tank is cracked. I called the local GMC dealership and gave them the VIN for the vehicle. They informed me that there is a corrective piece that is covered under warranty for some of these Envoys. It is based on the VIN number. Try calling the dealership and see if this helps! Also, we just replaced a cracked exhaust manifold! Envoy has 140,000 miles now! It goes to the dealership Monday so we will see if this gets resolved without spending $1200.

I have a 2003 Envoy XL with a V8.

My check engine light and low engine power lights go on and off every few days. I've had it in and out of the dealership, and they cannot identify the problem. The last trip they said there were multiple codes coming up on the computer, and they think that one problem can cause another and so forth until you have multiple issues that they cannot resolve, because they cannot find the originating source.

I was told that there was a carbon build-up in the butterfly valve of the throttle body. I had that cleaned out and the problem stopped for a few days. When the low engine power light comes on, I cannot go more than 10 mph and that is on a flat road. It cannot pull a hill with the light on.

This week the overhead console started leaking water during a mild rain. My driver seat is in a new position ever few days.

My mirrors move around. I have set and reset my seat and mirror positions with the driver information center as well, and reprogramming the option 1 on the driver door. I put my driver 1 key and keyfob in to start the car today and it promptly came up "Driver 2". I have no idea what to do and the GMC dealership is of no help.

I also was told on a recent visit that my rack and pinion seals were leaking, so I purchased an aftermarket kit to install.

Every time I take the vehicle in there is another problem to add to the list. Why do these vehicles have so many problems? Has anyone else found a solution for this?

I love the vehicle for the options and the smooth ride and power, but sometimes it just doesn't seem worth it!

My 2003 envoy has had the following problems since purchasing it used in 2006:

58,000 miles: O2 sensor went bad. Fixed it myself for $70.

92,000 miles: Cam shaft adjustment arm broke. Part not too expensive, but labor will kill you. $875.00

111,000 miles: Fan clutch stuck. Can be driven, but is loud and hurts gas mileage considerably. Expansive part: $350 plus labor (being done this week).

I'm selling this vehicle soon, and start buying old, simple trucks!!

I have a 2003 Envoy.

Looking for insight on the following:

1. When I turn the ignition to power on there is a clicking coming from inside the dash that lasts for about 20 -30 seconds and stops. No impact on performance. Thoughts?

2. My AC is erratic where the cool air comes out sporadically. Like this for a couple of years Thoughts?

I have a 2003 GMC Envoy XL V6 4x4.. I wish I would have read these comments before I bought it.

In the past year I have had to replace the fuel tank (got money back a few months ago thanks to GM FINALLY issuing a recall), the rear air controls no longer work in the back, left passenger power window motor went out, power steering hose went out, power steering pump went out, cam sensor, catalytic convertor, the fan clutch is now going out, and my low beams/daytime running lights no longer work.

This vehicle is great aside from the mechanical money pit it has become. I am afraid to keep it. From the list of problems I have read there are still a few that I have not come across which means (knowing my truck) I will. The dealer wants to charge 800.00 to fix the fan clutch. Luckily, I know someone at a parts store and a mechanic to put it in. It will end up costing approx 250.00. I am not sure what the cost will be to fix the headlights, since I am not sure what's wrong. If anyone has had problems with low beams, please post a comment.

I have already added a comment but I forgot that My heater and AC wants to come on when it wants to come on!!! We have to buy a new switch for that!

My 2003 GMC Envoy has remained nearly service free for five years. One problem I had was sudden acceleration causing me to hit an abutment. This happened one time and the dealer could find nothing wrong. My recent experience was with the service engine soon light. Does anyone know how to reset the light?

This is in referral to the engine light. If you have a Auto Zone near you, have them plug it in for errors then ask them if you can reset it. They will not push the button to reset it; you will have to do that. But I will tell you that your gas cap may not be on tight; if you tighten it, then drive it for a little bit, it will go off. And it came on for me yesterday and my fan clutch is faulty. GOOD LUCK.

For anyone with the gas tank problem. GMC will repair or replace the gas tank at no charge if your GMC falls within 10 years or 150,000 miles. While I have not yet had this problem, I did receive a letter from GM stating this. This is not a recall letter, so do not confuse this. This is a letter (dated June 2007) that if this problem exists, GMC will fix the problem. If you dealer has charged you for this, it is wrong. You should call GMC at 1-866-996-9463.

I have a 03 GMC ENVOY with the same problems listed by others. Bad Ignition switch caused all of the gauges to go hay wire and would not start. Bad Clutch Fan, had to replace, Service Engine Light Soon- Had Fuel Tank replaced. Temperature Sensor replaced. My Cat. Converter is bad and smells when running. Blower Motor Module (Blower Motor Resistor) had to be replaced to fix HVAC system. These are common problems with all ENVOYS. Defective/cheap OEM parts.

Does anyone know the difference between a blower motor resistor and blower motor module? We own a 2003 GMC Envoy and purchased the resistor. When I removed what I thought to be the resistor, I found there to be a different part. I know replacement parts may look different. The new part mounts right to the same spot and is shaped just like the old part. The difference is the female portion of the connector coming from the control. The original part has a 3 wire clip and the new part has a 7 or 8 wire clip. The wires with a two wire clip match perfectly to the blower itself. Any suggestions? Thanks.
