2003 GMC Yukon Owner Comments

problem #4

Gas gauge does not correctly reflect what is in the tank, have run out of gas or come close quite a few times due to incorrect readings, it will show 1/2 full and drop rapidly within minutes to empty. I've taken it in they said it was the gauge cluster in the dash so they replaced it, it happened again, took it back in and of course at that time it was out of warranty they said they have not heard of any problems at the dealership in regards to this problem and that they assume the sending unit is bad and would replace it if I paid for it, why this wasn't done the 1st time under warranty is beyond me, but I've noticed on the news that other vehicles are having similar problems and searching the web I see I'm not alone. They need to step up and fix the problem.

Fuel gauge on 2003 Yukon will show empty then full randomly and after fuel is added randomly (Yukon is on level ground). Gauge also sticks. January 3, 2008, I took the Yukon to the dealer. They could not duplicate. It has happened again December 2, 2008.

Driving 60 mph on a 20 mile bridge, the engine failed (engine light and traction control light were on. No power steering or power brakes. Nothing appeared to be overheated. 2 hrs later it started, 5 minutes later it killed again. Towed to nearest dealership. They road tested it and car failed again. Found 1 broken wire inside wire insulation. Repaired. Picked up car and it failed 1 mile later, took it back to dealership on "reduced engine power". they found 2 more broken wires. Replaced harness. One week later it happened again. After brief wait it started and ran for another day until I could get it to the dealership purchased from. They could not find anything wrong. Two weeks later it failed again. Tow truck took it to another dearlership. They changed another part relative to the fuel system and said it "may" be fixed. I refuse to pick it up or drive it again; it's dangerous and undependable. Have asked GM for another car and I am waiting for their response.
