2005 Toyota Sequoia: multiple warning lights

Filed Aug 13, 2016 · Airbags, Driver assistance · AL

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.

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.

While driving at 35 MPH, the check engine light, vsc off light, vsc trac light, and the emergency brake light all came on at once, and the vehicle stopped accelerating, and I experienced a dramatic decrease in vehicle power. I drove the vehicle home noticing a drastic change in acceleration as the sequoia would not accelerate normally; it would accelerate at a significantly reduced rate, topping out at 35mph on the flats, 30 MPH on an incline, I was able to reach 70mph going down hill on a highway. Since that day, during start up, the engine makes a high-pitch vacuum noise, which drops off and normal engine sound returns. All dashboard lights are normal, until 10-15 seconds after start, when the vsc off/vsc trac/brake lights all illuminate, and remain on until the engine is turned off and the poor acceleration and decrease power are now the norm. This is a very dangerous safety issue should this happen to someone accelerating out of an intersection, or needing more power on a highway.

At slow speeds on clean, dry pavement and normal braking conditions all warning lights on the dash will illuminate, the skid/traction control will start beeping and the ABS will engage for no apparent reason 0 while also making a grinding noise. This has happened twice in the past month. Toyota dealer indicated the problem is the "ABS and traction control actuator."

The vehicle has a failed air injection system that causes a reduction in the engine's power output. When the initial failure began there was a loud vacuum sound upon start up and all dash warning lights came on. Over time the sound went away but engine power is still greatly reduced. This poses a very serious safety risk as the vehicle can not accelerate adequately to highway speeds or maintain speeds on an incline thus posing a risk for accidents and as a result possible injury. Toyota was notified of the issue in summer 2012 but stated they would not cover or replace any components related to this as the vehicle was out of warranty. The vehicle was taken to the dealership toyota scion concord (concord, nc) and a diagnostic test was performed showing a failed air injection system. The replacement cost are approximately $3,500 and requires a service technician to break down the motor to replace the necessary components. With the cost of the system being significant this goes beyond the scope of a basic repair. 2nd generation sequioas (2008-current) also experienced failed air injection systems and toyota replaced the system in these vehicles but did not in the 1st generation although they share a similar powertrain.

Started car and hear a loud whining noise but no lights came on. Within 2 days the whining noise was not heard when starting car but trac off, vsc light, and check engine light were all on. Took the truck to mechanic and he changed the battery and flushed the brake fluid. Lights were off for about 2 more starts of the truck and all lights were back on. Took it back to the mechanic the next day and he kept the truck for 2 days, called toyota and they told him to replace the air injection driver. This was done 12 nov 10 and by 13 nov 10 all lights are back on again and the truck is having issues picking up speed.

Brake light, vsc light, low tire pressure light, ABS light, and one other light come on when it's cold. They go off when it's above 40 or so degrees. Replaced brakes and fixed parking brake (drove with it on because I got so used to ignoring all of the lights). Lights were off for about a week. 21 degrees out today and all the lights are back on. Will call toyota and discuss why I just spent $900 and the lights are still coming on.
