Problems with 2007 Toyota Camry Hybrid VEHICLE SPEED CONTROL

Cruise control does not work correctly on rolling hills which is likely going to cause collisions. the cruise control will allow the speed to decrease by as much as 5 mph while descending down the a hill, then as it begins to climb it quickly accelerates way over the target speed. this causes a whiplash effect to all passengers and may cause the driver to lose control and collide with vehicles. *tr

The posted date and miles of first incident is just a approximate figure but the dealership should have recorded the exact date and miles. a noise from under my hood was getting louder so i took it to the dealer and was told the noise was normal. a year or two later after taking it to different dealers for same issue my check vsc light came on while driving and my brakes failed. after the second failure during the week i took it to another toyota dealer and they said it was normal and safe. it was not. to date i haven't had the vsc error message occur but my brakes when reversing from park or when starting from a hill will initially lose braking power and roll a few inches before the brakes start working. is this really normal or safe? i don't want to believe what the dealership tells me anymore. please help. *tr

While parking, my vehicle suddenly accelerated while turning into a parking spot. i did not inadvertently press the accelerator, and the accelerator was not entangled in the floor mat. the vehicle rapidly accelerated over the curb, through an adjoining grassy area, and stopped after hitting a cement wall. later, the car was inspected by the toyota dealer where i purchased the vehicle. the dealer indicated there were no problems with the accelerator or other equipment that would have caused this sudden acceleration. *tr

My toyota camry hybrid 2007 model had the uncontrollable acceleration problem on multiple instances making it hard to control and once in a potentially life threatening situation. i called the closest dealership and took it for examination, they asked me to reproduce the problem on the spot, but i was not able to at that instant. the dealership then later said it was likely due to floor mats and i had the floor mats secured (even thought that did not appear to be the cause.) based on recent reports i am concerned that it is likely due to a different mechanical problem acknowledged by toyota. however i have not seen any recall or repair notifications for my car yet and i am concerned about the safety of my car. *tr

This complaint is about a 2007 toyota camry hybrid. i had many unusual occurrences when i first purchased my vehicle. none of them could be resolved because the toyota diagnostics said they did not occur. i assure you they did. the recent events surrounding toyota vehicles and at least what has been reported in the press regarding the inability to duplicate or see that the problem occurred is exactly what has happened in toyota vehicles. the dealer and manufacturer therefore conclude it is operator error. so when a malfunction occurs-probably caused by software-it is compounded by an additional software issue that will not allow anyone to figure out what happened. i am so disappointed in my vehicle as a result and even more disappointed in the people i turned over $32,000 to since everything was blamed on operator error. i assure you there was no operator error as is probably the case now with recently publicized events. i am convinced the diagnostic software or the interface between toyota's software and the diagnostic software should be checked out. *tr

I am having the same problem as mentioned in consumer complaint: odi case number: 10188438 (component: vehicle speed control:cruise control). whenever i start up a steep or slightly steep hill with the cruise control on, the car doesn't start to accelerate soon enough. then, it appears to accelerate all at once. i have started accelerating the car myself, rather than allowing the cruise control to accelerate, on hills. as stated in the previous complaint, the cruise control works fine on fairly level ground.

Cruise control varies speed by 7 mph hour when engaged during non flat terrain causing a safety issue with cars following. when on flat terrain the cruise control maintains its target speed within +- 1 mph with no problems. the safety issues occurs when the vehicle encounters rolling hills, the cruise control will allow the speed to decrease by as much as 5 mph while descending down the hill, then as it begins to climb will aggressively accelerate to 2 mph over the target speed. when the road flattens out again it will maintain the original target speed. at highway speeds, 70 mph, this causes safety issues especially when traffic conditions are moderate to heavy in that traffic follow will not have any indication that the speed is slow by 5 mph. this in turn will cause a hazardous situation where a collision could occur. this has been reported to the local toyota dealer and toyota support responded that all is working within parameters and no adjusts are planned. case # 200701250758 has been opened with toyota customer relations with no promise of action. *nm

I have a 2007 camry hybrid and have the same skid/lurch problem as the prius. my car is not being recalled and phone calls to the dealer, toyota as well as emails have not been recognized. this issue is not limited to recent products. please let me know how i can resolve this problem. *tr

The car's cruise control behavior on level ground is fine, but on rolling hills it's totally egregious, and indicates to me that this feedback control system may be close to instability and therefore potentially dangerous. i think that the control algorithm used is dreadfully sub-optimal, and has such long internal control-loop processing delays that its reactions to changing road conditions are alarming. what i find is the following behavior. the car substantially overshoots (by 10 mph or more) the set speed on the downhill portion of each hill, but then waits so long before reacting to the beginning of the next uphill portion, that it then undershoots the set speed by such a large amount (5 mph or more) that it has to "floor" the accelerator in order to catch up. still on the uphill portion, it then proceeds to overshoot the set speed again, before finally settling down to the desired speed. this cycle of events repeats over and over again as one negotiates rolling hills with the cruise control "on." why is the internal loop delay so long? why is the cruise control system not properly designed? (i happen to have expertise in control systems.) this control system really needs to be re-designed as a matter of priority! the cruise control's behavior could then be fixed by a simple firmware update. *jb

Tl*the contact owns a 2007 toyota camry hybrid. while approaching a stop sign, the vehicle accelerated into an intersection; however, after repeated brake application, she was able to stop the vehicle. the manufacturer was notified and she was advised to remove the floor-mats. the failure recurred after the mats were removed. the vehicle was taken to the dealer for inspection and the technicians were unable to identify the cause of the failure. the failure mileage was 497 and the current mileage was 38,000.
