Engine & coolingFuel system

I have been smelling gas from my car for years but just never had the money to get it looked at. I even called about recalls concerning the fuel system that I found out about through research in 2015 but was told they had been closed so I would be charged for the repairs even if it was previously covered under recall. I no longer fill my tank with gas because there is a leak. I just got my car back from the dealership, they state that I need a new fuel tank, and fuel lever sensor and sender. Also, have oil leaks in...

I have not driven my vehicle for 2 months because my mechanic told me my valve cover gaskets were leaking on to my exhaust manifold and that it why it was smoking when we stopped. I talked to my local gm dealer and they said it is not part of the recall so they could not help, so I have three choices let it sit in my driveway, pay several hundred dollars to get it fixed or drive it till it starts on fire. It has the 3800 motor like all the other cars in the recall. I can get a letter from my mechanic if needed.

Head gasket blown on 2004 pontiac aztek rally, 3.4L engine, 39,880 miles. I bought this car used 3 months ago with 37,000 miles at southtowne hyundai in riverdale, ga - 770-471-1000. They told me the car was mechanically sound and had passed a 60-point inspection. Recently, upon driving up a 5-mile hill, about midway the car started overheating. I let it cool down, turned off the a/c, turned on the heater and drove back approx. 5 Miles to the nearest service station. The car did not indicate any more overheating....

Tech's could not find a leak. There was no more overheating until a couple of weeks later. On my way to get an oil change, it happened again. Took it to pontiac service department. They diagnosed a blown head gasket. I researched the internet, this seems to be a common failure for this particular car. Pontiac said it will fix free of charge if I pay $1,100 for maintenance service (replacing all fluids - which had been done 3,000 miles ago at the southtowne hyundai). Lucky for me, the head gasket did not blow on a highway or heavy traffic but close to the dealership. I am now waiting for repairs through pontiac. *Tr

While driving car will completely shut down, losing steering and brakes. This has happened twice in the last sixty days. The first time the dealer couldn't find anything wrong. The second time a different dealer replaced a part that they thought could be causing this problem, but apparently it isn't. The third time I stopped to get gas and the car would not start. After several attempts the car finally started up and I drove it a short distance home. The dealer is going to check it over again and hopefully find a solution to this problem, before someone is seriously injured or killed because of the malfunction. *Nm

Dt*: the contact stated while driving at no particular speed the vehicle stalled. The lights on the radio intermittently illuminated prior to the stalling. This happened five times. The vehicle was put in park then restarted and operated properly. The dealership installed a new chip in an effort to remedy the problem, but this has not repaired the problem. The dealership suggested the vehicle be pulled over and towed in, to determine the codes on the computer.
