I BOUGHT A 2005 SUZUKI FORENZA. I HAD NO IDEA THAT THESE CARS ARE SO HAZARDOUS. ON THE SECOND DAY AFTER MY PURCHASE, THE CAR SUDDENLY WENT INTO REVERSE ON THE HIGHWAY IN RUSH HOUR TRAFFIC. I WAS LUCKY ENOUGH TO GET IT OUT OF REVERSE AND COAST TO THE SHOULDER. I HAVE SINCE FOUND OUT THIS IS AN ONGOING DEFECT THAT, AND THAT THERE ARE MANY MORE. I ALSO FOUND OUT THAT SUZUKI HAS BEEN MADE AWARE BUT SITS BACK AND DOES NOTHING ABOUT IT. THIS CAR HAS THE POTENTIAL OF BEING DEADLY AND NEEDS TO BE REMOVED FROM THE MARKET SO THAT PEOPLE LIKE ME AREN'T FORCED TO DRIVE SOMETHING SO UNSAFE. I CAN'T AFFORD THE COSTLY REPAIRS AND I CAN'T SELL THIS CAR. I AM SCARED TO DEATH THAT IN ONE OF THE MANY STALLS SOME ONE IS GOING TO HIT ME. IT SHOULD HAVE NEVER BEEN ON THE MARKET TO START WITH. I AM CONFIDENT THAT IF SOMEONE HASN'T ALREADY BEEN KILLED BECAUSE OF THIS DEFECTIVE CAR THAT THEY WILL BE.
2005 SUZUKI FORENZA. CAR HAS 78,000 MILES. MANUAL TRANSMISSION. TRANSMISSION JERKS, SLIPS AND IS NOW IS STUCK IN THE HIGHEST GEAR. WILL BARELY PULL OUT. THE PROBLEM STARTED WITH THE SLIPPING. THIS LEAD TO THE JERKING. THEN IS STARTED TO DOWN SHIFT VIOLENTLY WITH NO NOTICE THROWING YOU FORWARD. THESE EVENTS APPEAR TO ONLY PRESENT WHEN DRIVING IN TOWN CONDITIONS. HAVE NOT EXPERIENCED ANY ISSUES ON HIGHWAY. I HAVE HAD IT TO MECHANICS TWICE WITH NO SUCCESS. THE LAST TIME THE TRANSMISSION RANGE SENSOR WAS REPLACED. AT NO TIME HAS AN ERROR CODE BEEN PRESENT THAT WOULD LEAD A TRAINED MECHANIC TO A VIABLE REPAIR. THIS SITUATION IS DANGEROUS.

GEARS STARTED SHIFTING ON THEIR OWN, AND AT TIMES DID NOT SHIFT AT ALL...THANK GOD I WAS ALREADY ARRIVING HOME WHEN IT SUDDENLY JUMPED INTO PARK, BRINGING THE CAR TO A SCREECHING HALT, AT THIS POINT I WAS ALREADY SLOWING DOWN TO GET INTO THE DRIVEWAY. THIS HAPPENED AFTER I HAD A 1HRS DRIVE ON A HIGHWAY, IT WOULD HAVE BEEN A HUGE ACCIDENT IF THIS WOULD HAVE HAPPENED WHILE ON THE ROAD. SINCE THIS HAPPENED, I DID MY RESEARCH ONLINE AND FOUND OUT THIS IS A VERY COMMON PROBLEM WITH THIS VEHICLE. THE BAD PART IS THE TRANSMISSION RANGE SENSOR. I SINCE THEN HAD THE CAR INSPECTED BY A MECHANIC AND READ THE CODES P0700 AND P0705 THAT IS FOR THAT PART. *TR

THE TRANSMISSION FEELS LIKE IT IS SLIPPING IT WILL NOT SHIFT GEARS AND WILL NOT GO ABOVE 20MPH WITHOUT THE CAR BUCKING AND KICKING LIKE IT IS FIXING TO SHUT OFF. IT ONLY DOES THIS WHEN THE CAR IS NOT HOT. CHANGED THE RANGE SENSOR AND THAT WAS THE PROBLEM. *TR

THE SENSOR GETS DAMAGED, ENABLING THE CAR TO ACTIVATE REVERSE AND ACCELERATES WHEN PLACED ON DRIVE MAKING HARD PUMPING MOTOR NOISE. *JB
CAR ACCELERATES VERY SLOWLY. IT WILL STALL OUT IF THE GAS PEDAL IS FLOORED. THE CHECK ENGINE LIGHT WILL BLINK UNTIL THE CAR IS TURNED OFF. THE CHECK ENGINE LIGHT WILL STAY ON FOR SOMETIMES A FEW DAYS AT A TIME AND THEN TURN OFF. OTHERS HAVE COMPLAINED ABOUT THE TRANSMISSION RANGE SENSOR GOING UP MANY TIMES. *TR
MY CAR HAS BEEN PROPERLY MAINTAINED AND HAS A LITTLE OVER 65,000 MILES AND THE TRANSMISSIONS RANGE SENSOR CIRCUIT HAS STARTED MALFUNCTIONING. *TR
TL* THE CONTACT OWNS A 2005 SUZUKI FORENZA. THE CONTACT STATED THAT THERE WAS A LOUD KNOCKING NOISE COMING FROM THE TRANSMISSION. IN ADDITION, THE VEHICLE WOULD DECELERATE INDEPENDENTLY WHEN DRIVING AT 50 MPH AND ABOVE. THE VEHICLE WAS TOWED TO THE DEALER WHERE THE CONTACT WAS AWAITING DIAGNOSIS. THE CONTACT STATED THAT THE TRANSMISSION WAS REPLACED AT THE START OF THE YEAR. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS APPROXIMATELY 68,000. THE VIN WAS UNAVAILABLE. UPDATED 01/18/12*LJ THE CONSUMER STATED IN JANUARY 2011, THE TRANSMISSION COMPLETELY FAILED RESULTING IN HAVING TO REPLACE IT WITH A BRAND NEW ONE. IN JUNE 2011, THE VEHICLE JERKED EXTREMELY HARD WHILE DRIVING AND THEN WOULDN'T ACCELERATED. THE VEHICLE WAS TOWED TO THE DEALER AND THEY REPLACED THE TRANSMISSION RANGE SENSOR.

2005 SUZUKI FORENZA- TRANSMISSION SEEMS TO GET STUCK IN A HIGH GEAR- I DISCONNECT THE BATTERY AND THE SYSTEMS SEEMS TO RE-SET. THIS HAS HAPPENED 3 OR 4 TIMES. *TR
ABOUT 2.5 MONTHS AFTER I PURCHASED MY CAR, I HAD TO PUT A BRAND NEW TRANSMISSION IN IT DUE TO THE SHIFT SENSOR WENT BAD. NOW JUST AFTER THE WARRANTY RAN OUT IT IS BAD AGAIN. THIS TIME I AM GOING TO DRIVE THE CAR TILL IT DIES AND THEN SCRAP IT. I DON'T HAVE THE MONEY TO FIX IT. SUZUKI NEEDS TO FIGURE OUT WHAT IS WRONG WITH THEIR CARS, AND FIX IT. *TR
I BROUGHT THIS VEHICLE USED AND IT NOW HAS 37,500 MILES. I BARELY DRIVE IT AND KEEP IT GARAGED AND REGULARLY MAINTAINED. AFTER THE BUMPER TO BUMPER WARRANTY EXPIRED AND WHEN IT PAST THE 36,000 MILES (WARRANTY EXPIRED BEFORE MILEAGE REACHED) I STARTED TO EXPERIENCE HARD DOWNSHIFT AND HESITATING SHIFTS UPWARD (REACHES OR GOES ABOVE 3000 RPMS BEFORE IT SHIFTS). THESE HARD SHIFTS ARE MOSTLY BETWEEN 30-20 MPH AND ALSO OCCUR BETWEEN 5-20 MPH BUT SOMEWHAT SOFTER BUT STILL EASILY NOTABLE. THE POWERTRAIN WARRANTY IS FOR 100,000MILES/7YRS SO I TOOK IT THE DEALER AND TOLD HIM MY COMPLAINT. RIGHT OFF THE BACK THEY TOLD ME THAT THEY DIDN'T HAVE ENOUGH TIME TO REALLY CHECK IT OUT AND THAT ALL THEY COULD DO IS DRIVE. ALSO, HE TOLD ME THAT MY WARRANTY (BUMPER TO BUMPER) EXPIRED AND THAT IF THE GUY HAD EXPERIENCE WITH THIS TYPE OF COMPLAINT THAT HE MIGHT BE ABLE TO TELL ME WHAT IT WAS OTHERWISE I WAS GOING TO HAVE TO PAY $80+$8 TAX FOR DIAGNOSIS AND THAT IF IT IS ANYTHING ELECTRICAL WITH THE TRANSMISSION THAT IT WASN'T COVERED. OF COURSE AS I EXPECTED HE DIDN'T SEE WHAT THE PROBLEM WAS AND TOLD ME TO SCHEDULE THE $88 DIAGNOSIS. HE ALSO TOLD ME THAT SUZUKI FORENZAS ARE KNOWN FOR DOWNSHIFTING HARD BUT I TOLD HIM THAT IT WASN'T LIKE THAT BEFORE THE 36,000 MILE MARKER. I CAME BACK HOME THOUGH WITHOUT MAKING THE DIAGNOSIS APPOINTMENT AND READ MY WARRANTY DETAILS. UNDER "...WHAT IS NOT COVERED" FOR POWERTRAIN, NO WHERE DID IT SAY TRANSMISSION ELECTRONICS, INFACT IT COVERS 'TRANSMISSION CONTROL MODULE' WHICH IS AN ELECTRICAL COMPONENT OF THE TRANSMISSION, ALONG WITH MANY OTHER TRANSMISSION PARTS! I GUESS THEY OBVIOUSLY KNOW THAT THIS IS A COMMON PROBLEM SINCE HE TRIED TO CONVINCE THAT IS NORMAL AND THAT HE RIGHT OFF THE BACK TOLD ME THAT THEY DON'T COVER TRANSMISSION ELECTRONICS AND THAT THERE IS A CHARGE OF $88 FOR DIAGNOSIS. AFTER READING SOME OF THE POWERTRAIN COMPLAINTS ONLINE, IT SEEMS LIKE SUZUKI KNOWS THAT THEY HAVE A BIG PROBLEM ON THEIR HANDS AND ARE WAITING UNTIL WARRANTIES EXP. *TR
I PURCHASED A 2005 SUZUKI FORENZA. IT RAN GREAT FOR THE FIRST YEAR, AND THEN THE PROBLEMS BEGAN. MY TRANSMISSION KEPT SLIPPING AND IT WOULD FLASH D WITH A LINE THROUGH IT. THE CHECK ENGINE LIGHT IS ON AND WILL NOT TURN OFF. *TR
I WAS DRIVING MY 2005 SUZUKI FORENZA UPHILL GOING 35 MPH WHEN IT SUDDENLY STOPPED ACCELERATING AND SOUNDED AS THOUGH IT HAD SHIFTED INTO NEUTRAL. HOWEVER, THE CAR WAS STILL IN DRIVE. THE CHECK ENGINE LIGHT ALSO CAME ON. LEADING UP TO THIS INCIDENT, I EXPERIENCED ROUGH JOLTING WHEN MY CAR (WHICH IS AN AUTOMATIC) WAS DOWNSHIFTING FROM THIRD TO SECOND GEAR. I FEEL VERY UNSAFE DRIVING, BECAUSE I DON'T KNOW WHEN THE CAR WILL SUDDENLY STOP ACCELERATING. I HAVE SINCE BEEN TOLD THAT THE PROBLEM IS LIKELY THE TRANSMISSION RANGE SENSOR. *TR
KEY CANNOT BE REMOVED AFTER TURNING ENGINE OFF. RE-STARTED ENGINE AND CHANGED GEAR. COULD HEAR CLICKING BUT ONCE RETURNED TO PARK WAS STILL UNABLE TO REMOVE KEY. AFTER 3 ATTEMPTS OF CHANGING GEARS I WAS NO LONGER ABLE TO GO FROM PARK TO ANY OTHER GEAR. *TR
