2008 Nissan Maxima Lighting Problems

IT STARTED WITH WHAT THE TECHNICIANS MENTIONED AS A "MISFIRE," AND I KEPT SMELLING SOMETHING BURNING THROUGH THE AIR VENTS INSIDE THE CAR. AFTER SPENDING $1200.00 FOR A COMPLETE TUNE-UP WITH NISSAN PARTS, FIXING A MOTOR MOUNT, AND A CHEAP HOSE THAT CRUMBLED AS THEY WERE REPAIRING THE CAR IN FEBRUARY 2014 I HAD TO SPEND ANOTHER $500.00 IN NOVEMBER TO REPLACE THE SAME NISSAN SPARK PLUGS THAT BURNED OUT AFTER NO WHERE NEAR THEIR USAGE DATE AND REPLACE BACK COILS. I TOOK THE CAR TO NISSAN TO LOOK AT THE SERVICE ENGINE LIGHT AND ASK WHY ONE HEADLIGHT IS FOGGY AND THE OTHER ONE IS NOT IN WHICH THEY HAD NO ANSWER SO I HAD TO PAY $75.00 FOR THEM TO CLEAN THE FOGGY LIGHT AND NOW IT'S FOGGY AGAIN SO THEY SAY $1200 FOR A NEW ONE WHICH IS RIDICULOUS TO ME. THE PAINT IS FADING AND THE CHROME IS COMPLETELY GONE ON THE ROOF AND THIS IS 2008 MODEL WHICH MAKES NO SENSE TO ME. AFTER SPENDING THIS IN 2014, IN FEBRUARY 2015 I HAD TO PAY NISSAN $2000.00 TO REPLACE THE CATALYST CONVERTER, FIX AN OIL LEAK, TPM SENSOR FOR THE SECOND TIME, AND FOR A BRAKE FLUSH AND REAR BRAKES. I TOOK THE CAR IN TO NISSAN TODAY AND TIRE PRESSURE LIGHT IS ON SPENT TWO HOURS THEM FOR THEM TO TELL ME IT WAS A SMALL LEAK IN THE TIRE THAT THEY PATCHED AND SOMETHING KEEPING THE RIM FROM SEALING AROUND THE TIRE COMPLETELY. TODAY I GET HOME AND THE DRIVER SEAT WOULD NOT MOVE BACKWARDS OR FORWARD AFTER MY WIFE LEAVE TO GO TO WORK THE SEAT STARTS TO WORK AS I AM ON THE HIGHWAY DRIVING IN HEAVY TRAFFIC AND IT MOVES FORWARD ALL THE WAY TO THE STEERING WHEEL CAUSING ME TO PRESS DOWN FURTHER ON THE GAS WHICH WAS VERY DANGEROUS AND I WAS ABLE TO STRUGGLE TO PULL OVER IN SIDE MEDIAN IN ORDER TO MANEUVER OUT OF THE SEAT AND CUT THE CAR OFF. AFTER STANDING ON SIDE THE HIGHWAY, PRESSING THE SEAT DEVICE IT FINALLY MOVED BACK ENOUGH FOR ME TO CONTINUE DRIVING TO WORK. *TR
