Cruise Control problems of the 2005 Toyota Avalon

The contact owns a 2005 Toyota Avalon. The contact stated that while driving with the cruise control set at 55 mph, the vehicle surged forward to 70 mph without warning. The failure was experienced twice. The vehicle was taken to an authorized dealer, but the vehicle was not examined to determine the cause of failure. The manufacturer was made aware of the failure. The failure mileage was 100,000 and the current mileage was 103,000. The VIN was not available.

While en route from san juan to ponce, pr, I decided to use the cruise control on my Toyota Avalon 2005. It worked very well, until I decided to use the resume speed option of the cruise control. As soon as the resume movement was activated, the car accelerated suddenly and lunged forward at an unbelievable rate of speed that scared us, and I had to depress the brake pedal to disengage the resume option. This occurred twice and then I opted for not using the cruise control at all. Recently my car was serviced at furiel Toyota dealer here in ponce, where the recall requirements for the accelerator and oil hose were completed.

The contact owns a 2005 Toyota Avalon. The contact was driving up an incline, approximately 25 mph. The vehicle began to accelerate beyond the cruise control set speed. The driver applied pressure to the brakes to disengage the cruise control. The authorized dealer was notified of the malfunction. The vehicle has not been repaired at this time. The failure mileage was 59,000.

I had multiple incidences of my car surging in my Toyota Avalon. I would put my foot on the brake but the car wouldn't stop but would surge forward. At first this didn't scare me and I got a little used to it actually so that I thought I could handle it. But it kept getting worse. I drove on the highway between iowa city and cedar rapids a lot. I would always use cruise control. I would say it happened to me 10-15 times on the highway between cedar rapids and iowa city. I remember coming very close to rear ending someone when I had to slow down to exit but the car wouldn't slow down.

With cruise control (cc) on, between about 30 & 70 mph, on inclines that cause a speed decrease of 3+ mph, car downshifts more than the normal 1 gear, & surges ahead quite violently, with large rpm increases, to 3+ mph above that set, then slowly settles to the set speed. With the cruise control set at 70 mph on a level interstate, I slowed to 60 mph & set the "resume" function; it downshifted once, accelerating normally, until, @ 64 mph, downshifted again, more than one more gear & surged violently ahead, up about 3000 rpm & to 72-73 mph before returning to 5th gear, & slowing to 70 mph. The rapid increases are startling to all occupants, and could cause a loss of control, and the often rapid braking to maintain control, a real challenge for the tailgater behind on a cell phone! downhill, with cruise control on, it usually, but not always, speeds up excessively; more than with cruise control off. It usually acts normal on flat roads, and, except as stated, on high speed highways with gradual inclines. With cruise control off, none of these abnormal things happen. When the dealers shop foreman had me test drive a 2006 with him as passenger. And both cars did it he decided it was "normal". But even if all 05/06 Avalons do, it's not "normal". While I do know that downshifting gently in the right circumstances is normal, as a highly experienced commercial driver & aircraft pilot/mechanic, & avid cc user, I have never had a vehicle act like this. When I phoned corporate Toyota, they opened case #2005 0921 1138; had the "area rep. " investigate (he/she never contacted me, or drove my car); told me that since the "area rep" considers it "normal" my only recourse with them is to enter "arbitration". We like this car very much, & would like to keep it if this can be rectified. Surely it's a software glitch or something along that line. Please help solve this obvious design flaw, before a tragedy forces it. Thank you.

The contact owns a 2005 Toyota Avalon. The contact stated that when the cruise control activated it surged automatically and then level ed off two gears. The failure gave the impression that the vehicle lost control. While driving in light rain at 50 mph the cruise control caused the vehicle's front wheels to spin. Toyota stated that the failure was caused by a programming failure that needed to be repaired. The current mileage is 242,000 , and failure mileage was 3,000.

No accidents so far. Problem sonar cruise controlled cars. I have anew Toyota Avalon limited. I have the sonar cruise contol which works very well. Ptroblem when my car slows down suddenly becauseof the car in front, there is no warning for the car behind me. . Toyota was notified of this [problem and told me not to use the sonar in heavy travelled roads. That is no souution. There should be a fix to make the brake lights go on when the car is slowed down by the sonar. Toyota says that they do not go on. That is the problem no waarning to the driver in the rear of my car. Can anything be done to correct that problem? please let mer know. Shapm@bellsouth. Net. See also voq 10119009.

2002 Toyota Avalon has a potential problem with the sonar controlled cruise control equipment. When and if that car in front for some reason or other, will slow down quickly. The driver behind my vehicle has no idea as to what is happening as the brake lights do not show that I am slowing down, especially if consumer are traveling at high speeds. See also voq 10116392.
