2002 GMC Envoy XL fuel system complaints
Page 2 of 2: complaints 11 to 15 of 15, newest first, as owners wrote them.
The gmc envoy xlt experiences a total loss of power under the following conditions. When the fuel tank is at or below a quarter tank of gas the vehicle's gas pedal becomes inoperable and the forward velocity is lost to the point that if you are in traffic the vehicle will immediately began to slow down resulting in a completely hazardous and unsafe situation where the driver has no choice but to pull off the road or be rear ended. This has occurred on several occasions only under the conditions described above. Several gmc envoy xlt owners have expressed the same situation. This has been reported to gmc in 2005 but it appears that the problem is known but they aren't accepting responsibility as a manufacturer. Possible indicators may be the fuel pump assembly, fuel pressure regulator, or some other vital componet in the fuel system. I am sure gm knows.
While filling my 2002 gmc envoy, I observed gas pouring out of the top of the tank down over the rear axle and near the tailpipe. I noticed this because the gas pump did not shut off at the appropriate level. I called gmc and reported it. They were at first reluctant to give me the agency I could report this too but after speaking to a supervisor they finally told me I could report the possible defect to the federal safety agency.
Check engine light turned on. Taken vehicle to the dealer and found that there was a leak at the filler pipe and fuel tank which allowed fuel and vapors to escape. Dealer will repair for $900.00. *ak
Fuel tank has leak at joint where filler pipe and tank join allowing fuel and vapors to escape. Smelled fuel inside the garage. The dealer service manager said that the weld had failed, that it is a manufacturing defect, and that they had replaced the fuel tank for 2 other envoys for the same failure. There was no prior repair on the fuel tank or removal of the fuel tank.
