2007 TOYOTA CAMRY Power Trainautomatic Transmissioncontrol Module Tcmpcmtecm Problems

TL*THE CONTACT OWNS A 2007 TOYOTA CAMRY. THE CONTACT WAS DRIVING APPROXIMATELY BETWEEN 40-55 MPH ON NORMAL ROAD CONDITIONS WHEN THE ACCELERATOR PEDAL BEGAN TO STICK. THERE WAS AN APPLICATION OF EXCESSIVE FORCE TO THE BRAKE PEDAL WITH BOTH FEET. THE VEHICLE SKIDDED AND LOSS CONTROL AND SUDDENLY, THE ACCELERATOR PEDAL RELEASED. THE DRIVER WAS ABLE TO GAIN CONTROL AND RESUME TO NORMAL OPERATION. THE FAILURE OCCURRED CONSTANTLY AT LEAST THREE TIMES A WEEK. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER ON NINE SEPARATE OCCASIONS FOR THE IDENTICAL FAILURES. THERE WERE REPLACEMENTS OF THE TRANSMISSION CONTROL MODULE (TCM) AND TRANSMISSION. THE FAILURES CONTINUED WHICH THERE WERE NO RESOLUTIONS. THE FAILURE MILEAGE WAS UNAVAILABLE.

THIS VEHICLE WAS PURCHASED USED FROM HERTZ CORP. DURING THE TEST DRIVE WE NOTICED A HESITATION WHEN ATTEMPTING TO ACCELERATE AT SPEEDS BETWEEN 25 AND 45 MPH. WE ALSO DROVE ANOTHER 2007 CAMRY WITH HIGHER MILEAGE AND IT DID NOT HAVE THE HESITATION PROBLEM. WE ASKED HERTZ TO HAVE A TOYOTA DEALER CHECK OUT THE PROBLEM. THE COMPUTER WAS 'FIXED' WITH A SOFTWARE UPDATE. THE PROBLEM STILL OCCURRED SO IT WAS TAKEN TO ANOTHER DEALER. EVERYTHING WAS 'OK'. THE STATEMENT WAS MADE BY THAT TOYOTA SERVICE ADVISER THAT THE COMPUTER USES A PROGRAM TO DETERMINE THE DRIVING HABITS OF EACH DRIVER AND THE HESITATION PROBLEM WOULD 'SELF CORRECT'. YEAH RIGHT. WE PURCHASED THE LOWER MILEAGE VEHICLE, AND HAVE DRIVEN ALMOST ANOTHER 5,000 MILES, HOWEVER THE PROBLEM DID NOT 'SELF CORRECT'; IN FACT IT APPEARS TO HAVE WORSENED. THE VEHICLE WAS AGAIN TAKEN TO A THIRD TOYOTA SERVICE DEPARTMENT ON MARCH...

TRANSMISSIONS PAUSES BEFORE ENGAGING. *TR

I PURCHASED A 2007 TOYOTA CAMRY IN SEPTEMBER 2006. THE VEHICLE HAS 16,000+ MILES ON IT. THE VEHICLE HESITATES UPON ACCELERATION , AND AT TIMES LUNCHES INTO GEAR . THIS HAS CAUSED HONKNING AT US AND HARZARDOUS CONDITIONS, ESPECIALLY WHEN CHANGING LANES ON THE FREEWAY. THERE IS A LOUD INTERMITENT CLUNK WHEN TURNING CORNERS, BACKING UP, AND STOPPING. THERE IS AN APPARENT LACK OF POWER WHEN THE GEARS SHIFTS IN THE AUTOMATIC TRANSMISSION. ALSO, THERE IS VIBRATION WHEN BACKING UP WITH THE AIR CONDITIONER ON. WE HAVE HAD THE VEHICLE IN THE DEALERSHIP SEVERAL TIMES AND MOSTLY GET A SONG AND DANCE ROUTINE FROM THE DEALERSHIP. THEY SAID THAT EVERYTHING WE WERE EXPERIENCING WAS NORMAL OR DUE TO THE COMPUTER DESIGN OR EMISSION STANDARDS. THIS IS VERY DIFFICULT TO ACCEPT SINCE I HAVE BEEN DRIVING FOR 50 YEARS AND HAVE NEVER ENCOUNTERED ANYTHING LIKE THIS BEFORE. TOYOTA HAS AT THIS...

WHEN STARTING VEHICLE UP FROM A COLD IT REVS UP WHEN YOU PUT IT IN GEAR IT LARCHES FWD YOU HAVE TO APPLY THE BRAKES HARD TO STOP IT THEN THE REVVING GOES DOWN I ALSO GET THE ERRATIC CRUSE CONTROL WHEN USED THE SPED GOES UP AND DOWN CONSTANTLY SHIFTING 5-3 OVERSHOOTING THE SET SPEED TOYOTA SAYS THIS IS THE WAY THE MANUFACTURE DESIGNED THE CAR TO OPERATE

I BROUGHT THE CAR TO THE SERVICE DEPARTMENT ON 05/16/07, AND THEY REPROGRAMMED THE ECM( ENGINE CONTROL MODULE). THE CAR SEEMED TO BE MUCH BETTER IN TERMS OF ERRATIC SHIFTING AND ACCELERATION. I WOULD SUGGEST TO ANYONE WITH A SIMILAR PROBLEM TO HAVE THIS PROCEDURE DONE.*AK

I PURCHASED A NEW 2007 TOYOTA CAMRY IN JUNE 2006. AFTER RETURNING THE CAR TO THE DEALERSHIP SEVERAL TIMES BECAUSE OF THE SLUGGISH ACCELERATION FROM A STOP WAS CONSISTENT AND THE PASSING GEAR DOWNSHIFT FELT DELAYED AS IF THERE WAS A COMMUNICATION LAG BETWEEN THE TCM AND ACTUAL SWITCHING OF THE SHIFT SOLENOIDS AT SPEEDS LESS THAN 50 MPH. THE CRUISE CONTROL WILL NOT SET SPEED. ON STEEPER GRADES AND ON THE INTERSTATE THE DOWN SHIFTS ARE VERY FREQUENT AND AT TIMES VERY DRAMATIC. WHEN CRESTING A STEEP HILL THE TRANSMISSION DOWN SHIFTS AT THE CREST AND TAKES 2 OR 3 SECONDS TO RELEASE THE THROTTLE, PICKING UP ANYWHERE FROM 10 TO 15 MPH AND I HAVE TO BREAK SUDDENLY IN ORDER TO SLOW THE CAR DOWN. I WAS TOLD BY TOYOTA REPRESENTATIVE THAT A TECHNICAL SERVICE BULLETIN CAME OUT IN SEPTEMBER OF 2006 FOR AN ECM CALIBRATION ENHANCEMENT TO...

THROTTLE AND TRANSMISSION HESITATION WHEN STARTING OUT FROM STOP, AND WHEN ATTEMPTING TO INCREASE SPEED, IE: HAZARD AVOIDANCE, FOLLOWED BY SPEED OVERSHOOT. CRUISE CONTROL OVER REACTED TO SLIGHT GRADE INCREASE, SUCH AS AN OVERPASS, BY DOWN SHIFTING THE TRANSMISSION 1 TO 2 GEARS AND ACCELERATING PAST SET SPEED BY 7 TO 10 MPH. CAR WILL SLOW TO SET SPEED AND REPEAT THE DOWN SHIFTING AND ACCELERATION UNTIL THE CRUISE CONTROL WAS TURNED OFF OR THE ROAD WAS LEVELED. DURING LONG UP HILL DRIVING THE CRUISE CONTROL HAS TO BE TURNED OFF COMPLETELY AS IT PRESENTED A GREAT POSSIBILITY OF CAUSING AN ACCIDENT. THE DEALER MAINTAIED S THAT THE ENGINE, TRANSMISSION, AND CRUISE CONTROL OPERATED NORMALLY. *AK

THE CAMRY 4 CYLINDER HAS A MAJOR LAG IN RESPONSE TIME ASSOCIATED WITH LOW SPEEDS. THERE IS AN OBVIOUS DELAY BETWEEN THE GAS PEDAL BEING PRESSED AND THE ENGINE RESPONDING. THE DEALER ATTRIBUTES THIS TO THE DRIVE-BY-WIRE THROTTLE SYSTEM WHICH TOYOTA HAS ALREADY RELEASED A SOFTWARE UPDATE REGARDING THE TCM MODULE. THEY SAY THIS IS NORMAL. *JB

AT 200 MILES NOTICED SLIPPAGE IN TRANSMISSION. REPORTED PROBLEM TO DEALER, BUT WAS IGNORED AND TOLD THAT THE COMPUTERIZED SYSTEM NEEDED TO GET ADJUSTED TO THE DRIVER. OVER A PERIOD OF TIME THE PROBLEM WORSENED IN SPIT OF COMPLAINTS TO THE SERVICE CENTER. ON 11/16/06 THE CAR WAS FINALLY TAKEN IN FOR REPAIRS (I WAS TOLD BY A CUSTOMER REP. THAT THERE WAS A VALVE THAT WAS DEFECTIVE AND TOYOTA WOULD REPLACE IT. THE CAR WAS EXPECTED ON 11/17/06, BUT DUE TO A PROBLEM IT WAS SET FOR DELIVERY ON 11/18/06 AT 9AM. WHEN I WENT TO PICKED UP THE CAR THE SERVICE DIRECTOR SAID THAT THEY COULD NOT FIXED THE PROBLEM, AND THE TRANSMISSION WOULD HAVE TO BE REPLACED. I WAS SHOCKED AND DISAPPOINTED AT THIS NEW DEVELOPMENT. TOYOTA ARROGANCE AND THE DEALERSHIPS INCOMPETENCE AND IMPOLITE RESPONSE TO MY INITIAL CONCERNS IS INEXCUSABLE. THE MATTER AT THIS TIME IS...

THIS COMPLAINT IS RE: A NEW 2007 TOYOTA CAMRY LE 4 CYLINDER WITH AUTOMATIC TRANSMISSION. THIS CAR WILL HESITATE FOR A LONG PERIOD OF TIME BEFORE ACCELERATING FROM VIRTUALLY ANY SPEED (BEHAVIOR NOT SEEN WHEN ACCELERATING FROM DEAD STOP), REGARDLESS OF HOW HARD THE DRIVER PRESSES THE GAS PEDAL. PROBLEM OCCURS WHEN MOVING AT VIRTUALLY ANY SPEED AND THEN QUICKLY PRESSING AND HOLDING THE GAS PEDAL DOWN SO AS TO ACCELERATE QUICKLY. THIS BEHAVIOR IS NOT LIKE ANY OTHER CAR I HAVE EVER DRIVEN, INCLUDING A RENTAL 2005 4 CYLINDER CAMRY THAT I DROVE FOR A WEEK IN THE COLORADO MOUNTAINS LAST SUMMER (2005). SAFETY ISSUE IS THAT CAR IS UNPREDICTABLE IN SITUATIONS WHERE ONE MUST MOVE THE CAR TO AVOID TRAFFIC. EXAMPLE: ROLLING FORWARD INTO A LEFT TURN AT A GREEN LIGHT INTERSECTION, PRESS GAS TO CLEAR THE INTERSECTION BEFORE ONCOMING TRAFFIC GETS TOO CLOSE, THE CAR DID NOT...

THROTTLE RESPONSE DELAY IN 2007 TOYOTA CAMRY (4 CYL. AUTO) CAMRY - BOUGHT NEW 4/06 FROM TOYOTA OF NASHUA (NH). DEFECT IS A DELAY OF 1 1/2 SECONDS IN THROTTLE RESPONSE. DELAY WAS MOST NOTICEABLE AT NORMAL URBAN TRAFFIC SPEEDS OF 35 TO 45 MPH. A LIGHT INCREASE IN THROTTLE AT CONSTANT HIGHWAY SPEEDS IN THE 35 TO 45 MPH RANGE RESULTED IN THE ENGINE 1) USUALLY NOT REMAINING IN HIGH GEAR 2) HAVING NO RESPONSE FOR 1 1/2 SECONDS, AND 3) THEN ROUGHLY DOWN-SHIFTING, AS IF THE DRIVER HAD CALLED FOR STRONG ACCELERATION. THE CAR'S SPEED "SAGGED", AND THEN THE CAR'S ENGINE OVERSPED. THE DRIVER THEN HAD TO DECREASE THROTTLE TO PREVENT OVERSPEED IN TRAFFIC. PULLING OUT INTO TRAFFIC BECOMES UNPREDICTABLE AND DANGEROUS. DELAY AND/OR OVER-RESPONSE IN THE THROTTLE CONTROL'S ACTION MAY CREATE SKIDS ON WET AND ICY ROADS. LESS EXPERIENCED DRIVERS MAY BECOME UN-NERVED BY THIS KIND OF...
