Tank Filler Pipe And Cap problems of the 2004 GMC Envoy

I have had an overwhelming smell of gasoline for weeks and my speedometer was only working intermittently. I took my car to an auto store and had them put it on the computer the code read small evap leak so I bought a new gas cap to attempt to resolve the issue. That didn't work so I took my car to the mechanic for it to be checked out as my check engine light came back on. On the first visit he scanned the computer and codes read po 442 & 445 ? small/large emission leak, he checked all components and could find nothing. I took my car back as the speedometer issue was getting worse and the gas smell was still present the same code came up for the emission/evap leak and still nothing for the speedometer issue. He then did a smoke test and found that there was a crack in the filler neck of the plastic gas tank that cannot be repaired and must be replaced. He replaced the speedometer sender which still did not fix the issue. After much research I have found both of these issues to be a serious problem with other Envoy owners. I would like to know why there has not been a recall on these parts and why GMC is leaving the cost of repairs up to the owners. These are manufactureâ??s defects. This is supposed to be a reputable company. I have called into GMC support and they as well as staff at a GMC dealership stated that this was the same issue as was stated in a recall but my VIN number wasn't included so no financial help was given. $1,215. 29 later I have a new gas tank and my speedometer still does not work. This is ridiculous. . . Take ownership for your product malfunctions!!! how many complaints does there need to be before a recall is issued on these vehicle issues?.

I own a 2004 GMC Envoy with approximately 85,000 "highway" miles. My check engine light came on a few months ago an I had it analyzed at a large auto repair chain. It indicated a vacuum leak. The mechanic determined that the top of the pvc gas tank where the inlet value was mounted to the tank during manufacturing was likely the source as there was fuel stains running down the tank from this location! to add some additional support to this matter, the mechanic stated that another general motors vehicle of the same type had the same, exact problem the week before. Obviously this is not my problem alone. I contacted general motors and long story short, they refused to replace the tank because it was out of warranty. The GMC mechanic indicated that if it had 60,000 miles or fewer, he would likely have replaced it for me. I attempted to explain that a fuel leak is a very dangerous problem and I was concerned about my families safety. To explode or burn in an accident, because of this problem was unacceptable. This is not a mileage factor and it is not a wear part, it was simply not properly sealed when it was being manufactured. I feel that general motors should check into this matter as it is a serious safety issue that likely affects many Envoys and trail blazers. I hope that this notice will start a full investigation and a recall. A death from this defective part is very possible. Thank you, kent mayer.
