“THIS OWNER'S 2008 TOYOTA TUNDRA 5.7L DASHBOARD LIGHTS LIT UP INCLUDING THE VSC, TRACTION CONTROL, CHECK ENGINE AND 4 LO. THE 4 LO LIGHT WAS FLASHING. THE TRUCK WOULD NO LONGER GO PAST 3000 RPM ON SOME OCCOSIANS.

TOYOTA ISSUED AN EXTENDED WARRANTY TO COVER VEHICLES IMPACTED BY THIS DEFECT, CODE p0418. THIS IS A SAFETY ISSUE DUE TO LOSS OF POWER ESPECIALLY IF RANDOM AND UNKNOWN TIMES WHEN PULLING INTO TRAFFIC NORMALLY WOULD ALLOW TIME TO ACCELERATE SAFETLY BUT DUE TO THE SAIS MALFUNCTIONING IT COULD ACCELERATE SLOWLY AND CAUSE A COLLISION.”

“I have multiple problems with the dash lights going on and off , have taken it to car repair when scanned and had replaced relays many times. I have read many stories of people having the same problem with toyota tundras and no one can figure it out. Toyota should have a recall for this because it is not just one or two people with this same exact problem, it is many toyota tundra owners going through the same problems that i' am experiencing.”
“My truck drove fine then all of a sudden my check engine, vsc and traction control light came on. I brought it to the shop and the code read P 2440. It is in limp mode and the shifting is sporadic.”
