Cruise Control Problems of Toyota Camry Hybrid

For several months, the cruise control had only been working intermittently and my brakes seemed rough. The night before I brought my car in, all the lights on the instrument panel came on. On Aug 1, 2017, I got a diagnostic and it was the abs actuator, but I was told I also needed a brake job and an alignment so I went ahead with that $1,000 job. They could not diagnose the cruise control since it was "functioning" at the time. I had already replaced the abs system in 2013 and was told that I may apply for a reimbursement for that $3,600 job, but I am now out of the extended warranty/service campaign so I could not get reimbursed for the current abs failure replacement. After my brake job and alignment, the roughness did not seem to improve and the cruise control continued to malfunction. Foolishly, I rationalized that the brakes needed to be worn in, but soon my car started with a high pitched noise as I got in and out of the vehicle. The brakes also seemed to "slip" sometimes when initially starting the car. (foot on brake, start car, put into drive, and car would start to roll until I took my foot off the brake then reapplied it. ) I went back to Toyota hoping for a miracle and they again said you have to replace the abs, but the service campaign had not been re-extended and I was unable to afford another $3,600. So I continued to drive my faulty vehicle out of necessity. On October 12, 2017, the car began the high pitched noise and this time it didn't stop. I began driving in the parking lot slowly (20 mph) and then the brakes failed. Was able to stop by pressing very hard on the brakes. Since that day my car has been sitting at my workplace unused. Obviously, the abs system that was replaced in 2013 (still awaiting reimbursement) was replaced with another bad system. We need a recall!.

Warning buzzer, brake, check engine, no cruise control, hard brake pedal to stop. I paid to the dealer to diagnostic, and the abs actuator assembly with labor is almost us$1,700. Only something the sound of the buzzer and the lights turn off, and brake perfect. But must of the time, permanent noise and lights are on. To use the car is dangerous and noise no good for passengers. The problem start with vehicle in motion, in the city.

The contact owns a 2014 Toyota Camry Hybrid. While driving 75 mph with the cruise control activated, the vehicle stalled without warning. The vehicle was restarted, but the failure recurred shortly afterwards. The vehicle was taken to the dealer, but the technician was unable to diagnose the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 2,300. The VIN was not available.

2009 Toyota camry while on the state highway I set the cruise control to 70 mph, during the exit of the highway on my way home I stopped at a stop sign in back of others cars, switch the car on neutral while looking for some documents on my briefcase, when the light changed to green once again the transmission was switch to the drive position and without touching the accelerator pedal there was uncontrolled sudden acceleration incident of the car, and the tires start squealing, brake were depressed hard but the vehicle would not slow down, immediately was shifted to neutral once again, and turn off, because the car engine was in acceleration mode. Lucky that it did not crashed into the rear of a brand new Mercedes Benz. I had never experienced this situation before. The car had been used but the cruise control has not been set up. This car was already modified with the recall of the mat and accelerator gas pedal modification. The failure and current mileage were approximately 36,500. . Read more...

Cruise control set @ 70 mph speed limit on I-85 when a tractor-trailer truck rapidly closed the interval behind as I started up an incline. Without warning my speed quickly dropped and the truck moved dangerously close. Stepped on the accelerator to increase speed and within a second or two the cruise control further increased my speed. Do not know what the speed increase was because I was paying attention to the interval between the truck and my car and not what registered on my speedometer. After going over the hill's crest there was state patrol car in the median who clocked my speed at 80mph. Had not previously experienced speed drops and surges with the cruise control and was much more attentive to the actions of the cruise control for the remaining part of the trip. There were multiple instances where the speed would drop from six to seven miles per hour as the car started up an incline and then would rapidly accelerate, overshooting the setting by three to four miles per hour (once over five) before ultimately dropping back to the set speed. This is both a safety concern as well as uncomfortable when there is a series of rolling hills. The Toyota dealer could find no problem with the cruise control, finding no dtc fault codes and no abnormal findings after force testing the cruise system. I suspect the issue may relate to the electronic controls for the hybrid system. As the car went down hill, the gasoline engine appeared to be in "idle/coasting" state and the gps/energy display showed no energy flow to either the drive wheels or the battery from the engine. The electric motor, however, was in charging mode.

08" Camry Hybrid - when set on cruise control, the car inadvertently accelerates pass the "set" speed point when going up or down hill, by more than 20 mph before I disengaged the cruise control.

The contact owns a 2007 Toyota Camry Hybrid. The contact was driving approximately 55 mph with the activation of the cruise control. The engine revved excessively high out of control. The failure occurred twice after traveling for three hours on the highway. When the brake pedal was depressed the driver was able to gain control. The vehicle has not been repaired at the time of the complaint. The current mileage was 15,000. The failure mileage was 14,000.

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.

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.

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.
