Other Fuel System Fuel Gauge problems of the 2011 Chevrolet Cruze

On this date we scheduled a oil change with a dealer who has performed all maintenance, recalls and repairs since the purchase of our new car. We where notified that the car was ready for pick up that morning as we arrived we paid our invoice, the consultant made us aware that the engine light came on (first time since new?) this consultant did not document this engine light to our records. Well, the engine light kept going off and on during the next 10k miles (2 oil change later, out of warranty, my falt) I had this check engine light diagnosed by our dealer and they had the codes and then futher tryed to correct the problem. They wanted $800. 00 to install a new air intake maniflod and throttle body then continue to test for more problems with no garrantee of repair. I could not afford the repair and declined the fix. The other problem surrounding this car since April 21, 2014 was that the fuel gauge would not show full after fill up and would move up and down the scale on the gauge. The ac would come on at stange times when running the heater? well any ways that was 7 hours at the dealer and made for a long day. I had to return to pick up the cover they forgot to install over the spark plugs, and complained about the leather sets being soaking wet with water and that the car has had these problems since April 2014 under warrantee, the dealer did not want to help us? I purchased this car from them and purchased the 35k oil change extended warrantee and bumper to bumper warrantee? this dealer did all ! the maintenance, recalls and repairs. I'm glad we didn't go over the 1000 foot cliff at yellowstone when the brakes decided not to work (we learned later of the brake recall) they have a excuse for every question you ask, no reports on the all point exspection on our brakes and tires, password problem they say? I'm ready to buy a truck elsewhere now, poor gm an chevy.
