20090520ENGINE AND ENGINE COOLING
MY 1998 CHEVY LUMINA LS IS NOT ON THE RECALL L LIST FOR ENGINE FIRE RISK EVEN THOUGH TWO LOCAL CHEVY DEALERS HAVE TOLD ME MY AUTO HAS THAT SAFETY RISK. THE AUTO HAS THE SAME PROBLEMS THAT NEED FIXING BUT I WOULD HAVE TO PAY ABOUT $400 TO HAVE IT FIXED. THEY CHECKED TO SEE IF MY AUTO WAS INCLUDED IN THE RECALL BUT IT IS NOT. WHY NOT? FUEL AND OIL ARE LEAKING. ABOUT TO PUT ON 30,000 MILES ON THE CAR. TRIED TO SELL ME A NEW CAR BUT CANNOT USE THE NEW CARS WITH SHIFT BETWEEN SEATS DUE TO HAND AND SHOULDER PROBLEMS. *TR
