general problems of the 2007 Toyota Sequoia

Vsc, traction control and check engine lights randomly come on and vehicle suddenly loses acceleration and runs rough. I tried putting on new gas cap to no avail. I was almost rear ended going up a hill when the lights suddenly came on and I lost power. It has happened at highway speeds as well leaving me unable to safely accelerate . Mechanic reports this is an ongoing problem with Toyotas and costly to fix. Stated that Toyota fixed the problem in 2008 models but not in 2007.

Accelerator stuck when parking (<5 mph) causing vehicle to strike a curb and 1 ft retainer wall resulting in going airborne up a 3' bank, over a 6' sidewalk and 8' grass area to strike an office building. Location was kia drive lagrange, GA. My wife was driving and injured her right forearm. No broken bone, just bumped and remains sore. Vehicle was mfg in August 07. We took delivery in sept after placing an order. I saw recall on 08 thru 12 but not 07. Wondering if late 07 had a 08 accelerator installed? photo files were resized to smalller images for sending.
