2010 Toyota Tundra Double Cab Tundra Grade 4dr Double Cab SB (4.6L 8cyl 6A)
Cam sensor
 Before purchasing my 2010 Tunda 4.6, I did read some reviews about the engine light coming on shortly after purchasing from other reviewers. I purchased the truck based on Toyota quality based on past purchases. Well after 6 days and 370 miles, I said to myself no engine light should be good. Well day 7 engine light on brought to dealer and told them about previous reviews. Said engine oil was the problem. Waited 15 minutes and was given a loaner to use until the cam sensor (most likely) will be replaced.This is an assumption being that it's Friday and they will not be able to completely check the problem until Monday. Very disappointed in Toyota due to years of quality work.
