NHTSA Complaint #10204486 — 2007 TOYOTA CAMRY

I PURCHASED MY CAMRY LE 4 CYLINDER ON 1/31/07, AND I HAD NO PROBLEMS INITIALLY. HOWEVER, WHEN I USED THE CRUISE CONTROL, THE CAR DOWNSHIFTS TO THIRD GEAR ON A SLIGHT INCLINE FOR NO APPARENT REASON. THREE ATTEMPTS HAVE BEEN MADE TO DIAGNOSE/CORRECT THE PROBLEM WITH MY CAR'S CRUISE CONTROL; HOWEVER, THE SERVICE DEPARTMENT NOR TOYOTA TECHNICAL SERVICES DOES NOT KNOW HOW TO CORRECT THE PROBLEM. INFORMATION WAS SENT THE DATA TO TOYOTA FOR FURTHER ANALYSIS. WHEN THE CAR IS IN CRUISE CONTROL AND GOING DOWN THE HIGHWAY AT 60 MPH AND ENTERING AN INCLINE, THE CAR WILL SHIFT BETWEEN FOURTH (2600 RPM SURGES TO 2800 RPM) AND THIRD GEAR (3800 RPM TO 4000 RPM). AT 70 MPH AND THE CAR WAS IN CRUISE CONTROL AND GOING DOWN THE INTERSTATE HIGHWAY ON FLAT SURFACE, ENTERING AN INCLINE, THE CAR SKIPPED FOURTH AND DOWN SHIFTED TO THIRD GEAR. THE TACK REGISTERED 5000 RPM AND THEN SETTLED BACK TO 4500 RPM. IT APPEARS THAT THE CRUISE CONTROL IS OVERCORRECTION WHEN IT SHOULD DO NOTHING. THE CAR IS MORE THAN CAPABLE OF GOING UP SMALL INCLINES WITHOUT EVER DOWN SHIFTING OUT OF OVERDRIVE INTO THIRD GEAR. THE CAR PERFORMS WELL OUT OF CRUISE CONTROL. THIS PROBLEM IN TYPICAL TO ALL 2007 AND 2008 4 CYLINDER CAMRY'S. *JB
