ENGINE REVS UP, AND CAR LURCHES, TYPICALLY WHEN: - SHIFTING INTO DRIVE OR REVERSE AND/OR MOVING AWAY FROM IDLE; - ALMOST ALWAYS WHEN THE WHEELS ARE CRANKED ALL THE WAY TO THE LEFT OR RIGHT AND THE CAR IS MOVING AWAY FROM IDLE. THE LURCHING IS SUDDEN AND "VIOLENT" ENOUGH THAT IT CAN CATCH A DRIVER UNPREPARED - MY WIFE AND I ARE USED TO IT AND ABLE TO COMPENSATE, BUT WE AREN'T LETTING OUR 17 YEAR-OLD DRIVE THE CAR FOR NOW UNLESS ONE OF US IS WITH HER. ONGOING PROBLEM SINCE CAR WAS PURCHASED NEW. THIS HAS BEEN AN OCCASIONAL PROBLEM FOR YEARS - COMPLAINT WAS EVEN MADE WHILE CAR WAS STILL UNDER ITS 3 YEAR/36,000 MILE WARRANTY (NOTHING FOUND).

DRIVING ON THE HIGHWAY ON FEBRUARY 10, 2011, STARTED TO PASS A TRUCK AND NOTICED THAT I WAS LOSING POWER - I LOOKED AT THE TACHOMETER AND NOTICED THE RPM'S INCREASING. I TOOK MY FOOT OFF THE GAS AND GOT BACK INTO THE RIGHT LANE. AS I GOT FURTHER DOWN THE INTERSTATE, I HEARD A LOUD, SCREAMING NOISE, AND I CONTINUED TO LOSE POWER. I PULLED ONTO THE SHOULDER OF THE ROAD AS SOON AS IT WAS SAFE (I WAS ON AN OVERPASS). THE CAR CONTINUED TO RUN BUT IT WOULDN'T GO INTO GEAR. I HAD THE CAR TOWED TO A TRANSMISSION SHOP WHERE THEY CHECKED AND REPLACED THE CV AXEL ASSEMBLY AND REPLACED THE TRANSMISSION FLUID. IN MARCH 2011 I NOTICED THE ENGINE SEEMED TO BE MISFIRING SO I TOOK IT TO AN AUTO REPAIR SHOP WHERE THEY SAID THE PLUGS NEEDED REPLACED AND ONE MOTOR MOUNT WAS BROKEN AND NEEDED REPLACED. I WAS LEAVING FOR VACATION SO THEY SAID IT WOULD BE OK TO DRIVE TO THE AIRPORT AND RETURN AND THEN BRING BACK FOR REPAIR. I TOOK THE CAR BACK ON TUESDAY APRIL 5, 2011. WHILE CHECKING THE CAR OUT, THEY FOUND THE PART REPLACED FOR THE CV AXEL WAS ONCE AGAIN BROKEN, WHICH THEY REPLACED. I PICKED UP THE CAR ON FRIDAY APRIL 8, 2011. I LEFT THE AUTO REPAIR SHOP, DROVE APPROX 20 MILES WHEN I NOTICED THE SAME PROBLEM STARTING. I RETURNED TO THE AUTO REPAIR SHOP AND THEY SAID THE CV AXEL PROBLEM WAS AGAIN OCCURRING - THE SPLINES WERE BROKEN. CAR WAS TAKEN TO THE TRANSMISSION SHOP WHERE IT WAS FOUND THIS TIME TO HAVE AN INTERNAL TRANSMISSION PROBLEM, SAID THE CV AXEL ASSEMBLY WOULD BE WARRANTY, BUT IT WOULD BE APPROX $4,000 TO REPLACE THE TRANSMISSION WITH A REBUILT ONE. *TR

1) NO PRIOR EVENTS LEAD TO THIS PROBLEM IT JUST HAPPENED. 2)THE INSTRUMENT PANEL OF MY 2005 MERCURY MONTEGO LOST ALL GAUGES, SPEEDOMETER, LIGHTS,TURN-SIGNALS. THEN THE CAR COMPLETELY LOST POWER. 3) THE REPAIR SHOP IS STILL TRYING TO DETERMINE THE PROBLEM. *TR

MY 2005 MERCURY MONTEGO HAS AN INSTRUMENT FAILURE IN WHICH ALL WARNING LIGHTS STAYED ON. ONE LIGHT REMAINED ON AFTER IGNITION WAS OFF. THE BACKUP LIGHTS STAYED ON WHILE IN DRIVE PRESENTING A SIGNIFICANT SAFETY HAZARD. FOR EXAMPLE, A CAR APPROACHING FROM THE REAR, UPON SEEING FAULTY BACKUP LIGHTS ON MAY SWERVE TO AVOID. THIS SITUATION WOULD BE EVEN MORE LIKELY TO HAPPEN AT NIGHT ON A TWO LANE ROAD. NHTSA PREVIOUSLY CLOSED THE ORIGINAL INVESTIGATION DUE TO 'NO SAFETY DEFECT'. THAT REASON WAS BASED ON FORD'S INACCURATE STATEMENT TO ODI THAT THE BACKUP LIGHTS WERE NOT AN ISSUE. FORD LATER ISSUED TSB 06-6-2 WITH REVISION 06-17-2 BOTH ADVISING DEALERS THAT BACKUP LIGHTS PROBLEM WAS AN ISSUE. THE DEFECT WAS FOUND TO BE A FAULT IN THE WIRING OF THE INSTRUMENT CLUSTER PER THE LATTER TSB. BASED ON THIS, IT IS LIKELY THERE ARE THOUSANDS OR MORE VEHICLES WHICH HAVE HAD THIS PROBLEM AND FOR WHICH OWNERS HAD TO PAY OVER $700 TO CORRECT DUE TO NO RECALL. PLEASE RE-OPEN. (PREVIOUSLY REPORTED BY THIS WRITER WITH LESS INFORMATION). *TR
