problem #9

  • 76,000 miles


The door locks failed to operate. I was trapped inside and could not open the doors. The key was also prevented from unlocking the doors. After considerable effort I was able to unlock a rear door and exit there. Later I could neither lock or unlock any of the doors. The car was parked. It did not matter if the engine was running or not or if the "key bob" or door lock switch or manually pulling/pushing the lock lever; nothing would alter the locked status. Grateful there was not an emergency such as a fire.

I was driving along and wanted to put my rear passenger window down slightly to let air circulate. I noticed that it did not move when I hit the control from the front seat. Later after I stopped, I went around and opened the door and tried the switch on the door. The window would not open. I contacted Scion by email and they took down the information and assigned me case #150808054 and told me to contact them by phone. I did and spoke with lauren who was very gracious and took info from me but had no resolution for the problem and told me the dealership would have to give me a price on repairing it. The dealership contacted me and said it would be between $300 and $500 depending on what was wrong to fix it. The gentlemen told me there was nothing more to be done if Scion didn't offer to repair it for me. I am a senior citizen and cannot afford this type of cost to repair a window. Therefore I am driving with it unable to open. Now as far as I am concerned this is a major safety issue. If someone is in the backseat and for any reason would need to get that window down and couldn't it could be very serious. A window should work as long as the car is on the road and there is nothing to override the electrical system to open the window. This looks like a major safety issue to me. I went online and found that there are a lot of people having this issue with this particular car. Scion seems totally unconcerned and offered no help. What can be done if anything? you are my last hope for resolving this...it makes me extremely nervous to know that window cannot be opened for whatever reason it might need to be. I will appreciate any help you can give me on this. Thank you.

My 2008 Scion Xb lost power steering as I was driving it. Fortunately, I was able to pull the vehicle over without any creating an accident. After having the vehicle repaired, I was informed that the electronic steering control unit failed without any notice. This is a very serious safety issue that needs attention before someone gets killed!

  • Automatic transmission
  • 400 miles
The contact owns a 2006 Toyota Scion Xb. While driving approximately 20 to 50 mph, the headlights dimmed and visibility was reduced. The lights would illuminate again moments later. While driving 30 mph uphill, the vehicle accelerated to 60 mph. The brakes were applied, but would not function unless they were engaged at a rapid pace. Occasionally the engine shuts off, the front end shakes while driving 20-50 mph, and the cruise control switch failed to engage. The vehicle continued to burn an excessive amount of fuel after the oil was changed and the check engine light illuminated. The radio failed and the dealer stated that they would replace it when the parts arrive. The mechanic stated that the back of the bumper was split, which caused it to fall off of the vehicle. The dealer also offered her $14,000 for the vehicle only if she paid them $5,000. The dealer was unable to duplicate the failure; however, they stated that the failures were electrical. The failure mileage was 400 and current mileage was 12,000. Updated 02-14-08.
