Question about 2003 GMC Envoy
I Purchased this vehicle used with only 50,000 miles and felt secure that I had made a good purchase ( being that I only paid 14k) but now I,m not so sure! The first year, we made quite a few trips back and forth to our vacation home in Lake Havasu, but from my driveway here in LA to the driveway in Havasu is only 296 miles 1 way. After racking up 15,000 miles that first year, on one of the trips to the lake upon arriving the engine started making a loud noise as if the clutch fan was going to fall off. Well good thing I have a habit of always taking my tools with me on a trip because upon my inspection I found that the water pump was what needed to be replaced. So after waiting 3 days for the closest dealer (who was across the lake in Arizona ) to order the pump, I was able to replace it myself and we made it back home. Well that was at 66,550 miles, now I just barely hit 72,000 miles and last month on another trip down there I was cruising sown the I-40 with the cruise control set at 80 and all of a sudden while climbing a modest uphill part of the road (which its handled 100s of times before) The engine power just started to drop all the way down to about 25mph so I pulled off the side of the road with my family all scared inside the vehicle (cause I usually prefer making this trip at night) and me trying to figure what my next move would be because I had passed a sign about 20 miles back that said there was no services for the next 58 miles being that it was pitch-black that night and no service station for miles. I tried starting the truck again, it started right up! I checked my gages, they were all normal, and I heard no strange sounds so figured I'd try to make it to the next exit which was a rest area that was always filled with truckers when I pulled back on to the highway, it seemed as if nothing had happened it drove fine, I kept at 55 just incase but it was driving so beautiful that I began to wonder if I should skip my decision to exit at the next stop and continue to the service station where the lighting would be more preferable for me and my family (who were all wide awake now!) but just as I was coming up to that rest stop exit which was at the high point of this hill it started acting up again, like if my transmission was slipping or something. So I made that exit ended up calling AAA and had them tow us all the way back home in LA. I've had the transmission checked out and serviced since it was in there but that wasn't the problem, I've had the speed sensor checked out and that was ok, so its been parked now sitting in the driveway useless while I still have to make the payment and insurance costs. A friend of mine told me that itcould be a problem with the catylitic converter and that I should take it to a GMC dealer Service Center because the factory warranties that part for 100,000 miles or 5 yrs. My problem is that being in LA I don't really trust any dealers service center (You go for your normal oil change to keep your warranty on a NEW car, and they come back to you with a ridiculous estimate of things that must be attended to, but aren't covered under warranty, and if you chose not to at the time you'll be voiding your warranty for any problems later on! COME ON WHAT GOOD IS A WARRANTY) I was wondering if anyone else has had this type of problem with thier Envoy? Any suggestions would be grestly appreciated, Thanks!
Does your Envoy do this just when the cruise is on, or all the time?
