Toyota extended the warranty coverage for repairs related to illumination of the check engine light (malfunction indicator light) due to moisture/water in the air injection pumps and/or air switching valves for select sequoia trucks. It should be required to extend it to all sequoia trucks as it clearly recognizes this pump and valve assembly is defective in this model. The coverage extends for the lesser of 10 years or 150,000 miles but instead should be for the greater of the two. This repair costs $4000 and typically occurs when the truck value is near $7000. My truck is experiencing this problem and will not accelerate above 50 MPH which can be dangerous.

I have a 2005 toyota sequioa that my vsc track and vsc off lights and check engine lighs came on. It was on for 2 days and then went off. Then 6 mos later they came on again. The dealership codes are not showing correctly. There hare numerous complaints from others for years 2003- 2005 people are having this issue, some people got a easy fix with replacing gas cap and others paid to replace a air pump, gasket, several valves and wasted money. This should be a recall and toyota should pay for the repairs. I cant afford this repair, what can toyota do for me. Anything.

Vsc vsc traction control lights comes on as well as the check engine light. The vehicle accelerates poorly. This makes for a very dangerous situation because the vehicle can slow dramatically at highway speeds. Lights go off for a little while when the battery is disconnected but all lights and acceleration problems return shortly. Owners have spent thousands of dollars replacing parts without a long term fix. Spouse will no longer drive the vehicle because of this dangerous problem. Totoya needs to fix this widespread problem.

I experienced a problem with engine warning and vsc trac off lights going on. The check engine light also came on. My family and I were on a trip and our sequoia all of a sudden lost power. It slowed down dramatically even though the engine was fine. It was a very dangerous situation because we were on an interstate where the speed is 70 MPH. I also experienced all the brakes making a massive grinding noise while going slow into a restaurant. (the brakes have less than 3000 miles on them.) the parking brake light also comes on periodically.

I have vsc trac, vsc off, and check engine. If you give it a lot of fuel, it just sounds like it wants to go, but it doesn't translate into power in the rear end. I use my code reader and it showed codes p1441 and p1444. Says I may have: a) faulty vacuum switching valve (vsv) for air injection control circuit, b)faulty air switching valve number 2, or c)faulty vsv for air injection system. This is the second time this happened to my sequoia, and this seems to be a recurring issues for toyota sequoia owners and in fact it is a recurring issues for other models as well. This cost me approximately $2200 last time and now 2 years later it is back for another $2200 to repair. It's all the over the internet about this vsc trac, vsc off, and check engine, it needs to be recalled!

Vsc vsc traction control lights came on as well as the check engine light. The vehicle was accelerating poorly. The dealer replaced the air injection control drivers and then all of the warning lights were off. The following day all of the warning lights were back on again and the vehicle was accelerating poorly again. I returned the vehicle to the dealer and I was told that another repair was needed now. The air pump set needs to be replaced for $1,700.00. Thousands of sequoia owners have reported this problem but toyota has not issued a recall.

A couple of days ago, when I was driving on the highway, my sequoia suddenly stopped accelerating. Trac light and vsc light and check engine light came on. My speed would not go above 40mph and would not even brake. I was in the left lane and the cars behind me were going pretty fast and almost hit me. I am lucky there was no car in the right lane, so I pulled to that lane just in time. It was a scary moment for me because my kids were with me also. I always thought of toyota of having safety in their cars, but when I came home to research what might be happening to the car, I found out many people are having the same exact problem and thus it is a manufacturers problem. I am suprised toyota is not doing anything about this. Do they not care of the safety of the consumers? The milage on my sequoia is only 39,000 and I do not drive it too often, and also have maintained it very well. We spend so much money on this car and this vehicle really was not worth it if it came with so many factory defaults. Please follow-up on this issue to have it resolved.
