MY CAR SUFFERED FROM THE SMELL OF ROTTEN EGGS FROM THE EXHAUST SYSTEM WHENEVER STOPPING THE VEHICLE. THE DEALER REPLACED THE OXYGEN SENSOR 1ST. A "CRACKED" VACUUM HOSE 2ND. ALL 6 FUEL INJECTORS & SPARK PLUGS 3RD TRY. THEY THEN BLAMED IT ON THE OXYGENATED FUELS WE HAVE IN CALIFORNIA. IT STILL STINKS LIKE CRAZY WHEN COMING TO A STOP OR PARKING AFTER DRIVING IT. IT MADE MY WIFE SICK ON A NUMBER OF OCCASIONS, BUT THEY STATED THAT THERE WAS NOTHING ELSE THEY COULD DO TO CORRECT THE PROBLEM. MY AIR CONDITIONER HAD LEAKED IT'S FREON OUT 3 TIMES BEFORE I DEMANDED (AND PAID FOR) A LEAK TEST THAT REVEALED MULTIPLE LEAKS. ALTHOUGH WARRANTY EXPIRED I DEMANDED REPAIRS DUE TO THE HISTORY OF PROBLEMS. THEY REPLACED EXPANSION VALVE, RECEIVER DRYER, GASKETS & O-RINGS. THE COMPRESSOR FAILED IN LESS THAN 2 WEEKS. I HAD TO GO TO BATTLE WITH THEM AGAIN TO GET THAT PROBLEM CORRECTED. I IMAGINE THEY REALIZED THE DOCUMENTED HISTORY BY NOW, SO THEY REPLACED THE COMPRESSOR AT NO CHARGE. *AK
