FUEL TANK OVER FLOWS AT EVERY FILL UP. *TR
GAS TANK OVERFLOW ON JEEP WRANGER. *TR
I STOPPED AT A RED LIGHT BEHIND A FORD EXPEDITION. WHEN THE LIGHT TURNED GREEN, I LIGHTLY DEPRESSED THE GAS PEDAL AND THE CAR IMMEDIATELY ACCELERATED OUT OF CONTROL. THIS HAD NEVER OCCURRED BEFORE. I HIT THE CAR IN FRONT OF ME AND WAS ABLE TO AGGRESSIVELY HIT THE BRAKES TO SLOW DOWN ENOUGH TO SLOW THE CAR AND SHIFT INTO NEUTRAL. THE CAR WAS TAKEN TO A JEEP DEALERSHIP AND THEY KEPT THE CAR FOR A NUMBER OF DAYS. THEY STATED THEY COULD NOT FIND ANYTHING WRONG AND THEY BLAMED THE INCIDENT ON AN AFTER MARKET FLOOR MAT. THIS WOULD MAKE SENSE TO ME IF THE ACCELERATOR WAS JUS STUCK AT THE CURRENT SPEED, BUT THE ENGINE KEPT SPEEDING UP AND THE TIRES WERE SPINNING WHEN I WAS DEPRESSING THE BRAKES. THE CAR ACTED LIKE I HAD THE GAS PEDAL FULLY DEPRESSED. *TR
THE VEHICLE FUEL TANK OVERFLOWS WHEN FILLING. THIS IS CAUSING FUEL TO SPRAY OUT ONTO MYSELF, ONTO THE PAINTED SURFACES OF THE VEHICLE, AND SPILL ONTO THE GROUND. THIS HAS BEEN AN ONGOING ISSUE SINCE THE VEHICLE WAS PURCHASED. *TR
WHEN FILLING MY GAS TANK, I FILLED THE TANK TO THE BRIM. NOT ON PURPOSE, GAS CAME GUSHING OUT OF MY JEEP WRANGLERS GAS TANK, ALMOST A QUARTER OF A GALLON. NOT LIFE THREATENING, BUT COST ME ABOUT 2 DOLLARS IN GAS.
SERVICE ENGINE LIGHT. LEAK IN FUEL TANK.*AK
POOR GAS MILEAGE. STICKER CLAIMS 16 MPG CITY AND 19 MPG HIGHWAY AND I STRUGGLE TO GET 11 OR 12 IN THE CITY DRIVING CONSERVATIVELY AND USING QUALITY MID GRADE GASOLINE. MY LAST TANK I GOT 10.86 MPG. WITH CITY AND HIGHWAY COMBINED I STRUGGLE TO GET 13 OR 14. I FIGURE THIS WILL COST ME AROUND $1000 OVER THE COURSE OF MY 4 YEAR LEASE. I HAVE TALKED TO OTHER WRANGLER OWNERS AND THEY EXPERIENCE THE SAME POOR MILEAGE. I WILL NEVER BUY ANOTHER JEEP PRODUCT. *NLM
I'VE HAD MY 2003 WRANGLER SIERAH FOR 3 MONTHS AND HAD THE CHECK ENGINE LIGHT CAME ON TWICE. FIRST TIME WAS A PURGE VALVE SOLENOID AND THE SECOND TIME IT WAS THE CHARCOAL CANISTER AND THE WHOLE GAS TANK HAD TO BE REPLACED ALONG WITH ANOTHER SOLENOID. NEITHER OF THESE FAILURES LEFT ME STRANDED BUT SHOULD NOT HAVE OCCURRED ON A JEEP WITH LESS THAN 5000 MILES ON IT. *LA
