While driving in town at about 25 MPH, the car will accelerate by itself to 30mph, even if the accelerator is released. Pushing down on the accelerator has no effect. The acceleration is brief and stops by itself. This has happened several times over the last few weeks. Cruise control not engaged. The car computer was re-flashed at the dealer year to address to address sensitive accelerator issues.

Adaptive cruise control problems by model year
What owners say
On a flat surface in cruise control traveling at 40+MPH, brakes applied, then resume is activated, and vehicle surges ahead unexpectedly. On a hill at 50 MPH, with cruise control on, the vehicle suddenly accelerates excessively causing the vehicle to veer right or left. This condition has existed since I purchased the vehicle new. After complying numerous times, the authorized toyota dealer could "detect nothing wrong with the cruise control". They did not offer to do a test drive. I have put up with this condition for a long time, but the problem is now much worse and dangerous to drive.
Has anyone ever considered the toyota vehicle speed control, vsc, system as a source of sudden acceleration? A code p1578 means brake system malfunction relating to the cruise control brake switch. If the brake switch develops an intermittent, stepping on the brake pedal will not cause the cruise to disengage. The driver will fight the cruise control with the brakes and think its a sudden acceleration. The toyota vsc system needs to be included in the protocol for their vehicle exams as well as independent forensic examiners.
Tl* the contact owns a 2006 toyota avalon. The contact was driving with the cruise control set at approximately 80 MPH when she noticed that the brakes were not responsive when applied. The vehicle did not begin to slow down until the cruise control was disengaged. The contact notified the dealer of the failure but the vehicle had not been repaired at the time of the complaint. The failure mileage was approximately 53,000. The current mileage was approximately 58,800.
I have a 2006 toyota avalon limited. On 2 occasions, while in cruise control, I attempted to uptick the stalk to increase speed one MPH. The car accelerated rapidly well over one MPH whereupon I canceled cruise control and everything became normal.
Tl*the contact owns 2006 toyota avalon. While driving 65 MPH on cruise control the vehicle continued braking on its own. The contact deactivated the cruise control because the brakes continued to engage on their own. When the cruise control was turned off, the vehicle surged forward and almost hit a another vehicle. Two weeks ago the contact surged forward while driving 30 MPH. She took the vehicle to the dealer and suggested that it was the computer in the vehicle. The dealer inspected the vehicle and stated that the computer did not have any problems. The contact stated that her steering wheel became stiff several times and the dealer stated that there was nothing wrong with her power steering. The manufacturer was not contacted. The failure mileage was 35000 and the current mileage was 42800.
Our 2006 toyota avalon (limited) was in cruise control set to highway speed, about 60 to 70 MPH. For a reduced speed zone, the car was slowed by 10 MPH using cruise control. After the reduced speed zone, cruise control setpoint was increased 10 MPH to return to the previous highway speed, and the car continued to accelerate uncontrollably to more than 80 MPH. Then, the brake was applied which took car out of cruise control. The car slowed, and cruise control was reset to highway speed. The problem did not recur on that trip in 2006, but there have been other cases of uncontrolled acceleration since the above incident.
2006 toyota avalon - during first year of ownership, vehicle engine revved strongly while applying the brake while going about 30 MPH. The car sounded like it waned to go 60 MPH or more and leached, but I was able to stop it by pressing harder on the brake.this happened on 2 or 3 occasions. At first I thought I was just not use to the vehicle and hit the brake and gas pedal together, but I had serious doubts. I now realize I was experiencing the current problem. It only happened during the first year of driving and has not happened to me since. I doubt this was due to a stuck pedal, but some electronic issue is at fault (perhaps the cruise control system).
We have a 2006 toyota avalon. When that vehicle is in cruise, and accelerates for a hill, the force is so strong that it's like the accelerator was punched for passing. That behavior has existed since the vehicle was new. Since we live in the hilly part of arkansas, we never use our cruise control on local roads. We have noted many recent reports of sticking accelerator pedals, and have wondered if the resultant crashes were actually caused by a malfunctioning cruise control system, in conjunction with the reported pedal sticking issue. If that is true, then toyota's current plans to add shims will not resolve the problem.
2006 avalon accelerates from 40 miles per hour to 100 miles per hour when in the cruise control -- I feel my life is in danger and I do not use my cruise control because of this, but I am afraid that it may come in accidentally -- please help me!
Tl*the contact owns a 2006 toyota avalon. While driving 60 MPH with the cruise control engaged, the electrical system speed control setting decreased the speed to 10 MPH. The dealer was unable to diagnose the failure. The failure mileage was 35,000.
The transmission poses safety problems because it is very uneven and unpredictable, shifting when you don't expect shifting, at lower and higher speeds and in cruise control.
