I took the vehicle to my dealership because I have four warning lights illuminated, they were brake, traction control, ABS, vsc. The dealer diagnosed the problem to be the right rear and left rear ABS sensors and cables with a replacement cost os $1357.04 plus diagnostic fee of $59.66. I asked why the sensors were defective and needed replacement, they told me it was due to corrosion from road salt. This seems like a manufacturing issue!! I've seen a Scion service bulletin (s-sb-0040-09 dated July 6, 2009) that addresses this issue. I have asked the dealer and Scion if they could help me out in any way and they're answer was no. I realize my car is our of warranty but why should an owner of a vehicle have to spend $1400 to replace components that the manufacture has since corrected the design due to this problem?

The contact owns a 2009 Toyota Scion Xb. The contact stated that while driving 65 mph, she began to decelerate and approximately seven hundred feet later, the vehicle accelerated independently. The vehicle was taken to a dealer for diagnosis where the contact was told that she must have accidentally engaged the cruise control. The failure recurred and the vehicle was returned to the dealer where it was found that the battery had been disconnected. The failure recurred but the dealer stated they could not find a cause for the failure. The vehicle also experienced brake failure. The vehicle had not been repaired. The VIN was unavailable. The failure mileage was 8,000 and the current mileage was 39,000.

The issue I am having with my vehicle is the traction control. There is no way to disable it permanently. I have contacted the manufacturer several times to resolve this issue but they were unable to help. The intersection exiting my neighborhood is often busy and occasionally there is loose sand and gravel at the exit. At times, to cross the intersection safely, I will need to step on the accelerator a little more than usual. If my tires so happen to be sitting on a patch of loose sand or gravel, the traction control will activate when I accelerate. This cuts the power from my engine and instead of briskly crossing the intersection, my car, at a snails pace, crosses the intersection. The more time my vehicle spends in the intersection, the greater chance of an accident. The power is cut for too long in my opinion and I feel that my vehicle would be much safer without it. A little spin of the my tires would occur when I'm on the loose sand and gravel but once on normal pavement, it would be business as usual. With the traction control activated, there is a delay and once on normal pavement, it still has reduced power. The car does allow the driver to turn off the traction control at a stop but it reactivates after reaching a certain speed. I do not always know when I happen to stop on a patch of loose sand and gravel and I won't always remember to turn off the traction control at every stop.

While at a drive thru and foot firmly on the brake my 2009 Scion Xb surged by releasing the pressure on the brake, I quickly removed my foot and reapplied pressure and it did it again at a stop light same occurrence. Vehicle at both these times was not in motion. I took it to the dealership to ask if problems had been reported as both these instances happened within minutes of each other and they stated to leave the vehicle and they would check it out. However, I told them I needed a car they said service was closed and was unable to provide me with a car in order for me and my family to get home and for work the next day. The dealership was open it was 7:15pm at night but I could not get a loaner car in order for them to properly check my brakes and acceleration issues. I asked them to write down that I had approached them on the subject and they said they would. The next morning while going to work the vehicle was in motion going down a hillside when I applied brake the vehicle slowed as it should but again there was a surge in power and it accelerated and I had to remove my foot quickly from the brake and reapply to bring the vehicle back under control. We are again contacting the dealership today for another proper inspection.

I purchased a Scion 2009 Xb for my mom. A few months ago, she complained it accelerated unexpectedly in her driveway. I assumed operator error. She was killed in it two weeks ago when it left the roadway at an extremely high speed and witnesses said it accelerated out of control. She traveled 750 feet after she left the roadway and was severely injured when it hit a very deep drainage ditch. She died the next day. There was no evidence of braking at all but she missed several people and several large trees. Updated 05/19/10 updated 06/17/10 updated 9/27/11

I was driving in a 35 mph zone, I set my cruise control. When I tapped the cruise control up 1 mph my car accelerated to almost 57 mph. I had to hit the brake to get the cruise control shut off. This happened again about 5 months later, I was on the highway, my car accelerated from 65 mph to 80 mph, I again hit the brakes to shut off the cruise control. This resulted in a speeding ticket, since the officer had no interest in my vehicle trouble.

The (Toyota) Scion Xb has the same accelerator problem, I put in a floor mat on top of the issued floor mat and it has gotten stuck 2 or 3 times on the accelerator, luckily I was able to depress the brake strong enough to get into park and stop the vehicle, the worse case I drove over the island in my parking lot. I have since removed the extra floor mat and have not had a problem with this issue since. I know it's late notice but I just found out about this site.
