I have a 2002 toy Sequoia. It is just getting ready to roll 200k. I had it in my local shop to get my shocks and front wheel bearings replaced. They also replaced part of the rack-pinion. I have had issues in the past with the vsc lights coming on and staying on until the car was turned off and turned back on. the dealership says they have dealt with this issue. So my new issue began when I picked my car up from the shop. When I would push the gas the car would stall and sputter. The vsc would also come on when I was turning corners or hit bumps. I took it to the dealership. They did another alignment to fix the sensor and said I would be good to go. Now whenever I drive on dry roads the vsc skid warning comes on. I loose power and have issues steering. I live in the mountains where there are no straight roads. Last night with my 5 children in the car this happened and I went off the road. I am by no means driving aggressively. Luckily I was on the bank side instead of the cliff side of the road. It was terrifying. The dealership and my local shop say that there are no codes on the computer.
