Problems with 2003 GMC Envoy XL WHEELS

I had been driving and pulled into a fast food restaurant and when i got out of my vehicle i noticed the smell of gasoline being close to a gas station i thought nothing of it when getting back in my vehicle after retrieving my food i now smelled the gasoline inside my vehicle still thought nothing that maybe the fumes were just lingering until the next day when the smell was stronger so strong that my child with asthma immediately had to get out of the vehicle so being cautious as anyone i had my husband take a look he smelled the gasoline but couldn't find a leak so he took it to our local mechanic who then diagnosed the problem and removed the tank and replaced it with a used tank and whatever part was needed to fix the issue so since then i have not smelled anymore gasoline but my check engine light refuses to go off not to mention i receive a letter in the mail stating that there was some sort of recall on my exact year and make of vehicle and that i could send in a claim to get back the $500 i put into fixing the vehicle thinking it was now safe for my family so i paid to fix the problem only my new tank is used so i'm guessing i'll be having this issue again at some point which is very scary considering i drive my children in this vehicle plus i'm out the $500 still have the same issue which i cannot afford to fix again should the problem arise and i didn't keep the receipt from my mechanic thinking problem solved i put it aside it threw it away so i'm just curious is there anything i can do because knowing the tanks have issues and i've just paid $500 for another recalled tank pretty much so i'm at a point where i have no option but to take a loss on the money i paid to fix the vehicle before i knew about the recall not to mention i've had to replace the tie rods twice and it's popping again when i make turns i love this vehicle but now i'm super nervous of it

Vehicle power steering hose busted. my truck isn't idling right it sounds like my transmission is slipping. also my tire traction seems off and i repeatedly have to put air in tires. tires always makes a certain sound on the highway, i don't know if its normal or not. *tr

I had lost 3 center pieces that covers the lude bolts. i spoke the company about the above and they stated they hadn't had any one to complain. but after great effort it was resolved with me being reimbursed with the 1 i had purchased and they replaced the other 2. i had spoken with 2 of my co-workers and they had a similar complaint, but did not pursue it. now my cruise control has gone out and may vechile only have 16,000 miles on it and i haven't use d it. the way i found out it was not working was we were taking a trip and the cruise would not work. i now have to take it in for repair and i am dreading it will be a ordeal. since i have to take it in to the chevrolet place instead of the dealership i purchased it from because of the poor service.*ak
