“About 2 weeks ago my truck was hesitating and my check engine/off trac light was on. The car would not go above 40mph on city streets or highway. I went to a Toyota dealer in puerto rico, they said the codes were p0052, p0456, p2140, p2442 secondary air injection system is bad and would cost $2,458.08 for repairs. I don't know if it is covered by any warranty. It is a 2012 Toyota Tacoma pre-runner.”
NHTSA complaint #11235367, filed 2019-07, 77,500 miles“Secondary air injection system truck would not accelerate and lost power. I've noticed it has done this since new. I now have 37,000 miles on it and have received messages check engine light and trac off messages. This is very dangerous as you have no engine power when entering into traffic. The truck will not go over 35 miles an hour and takes for ever to gain speed.”
NHTSA complaint #10940024, filed 2017-01, 37,000 miles“I took my 2012 Tacoma into service today with a trac off and check engine light on. I was told that the secondary air injection switching valve needed replaced at the tune of $1300. I see that many others have had this issue and with 37k miles, I find it unreal that this isn't covered under the powertrain warranty.”
NHTSA complaint #10881334, filed 2016-06, 37,000 miles“I'm a owner of Tacoma pre-runner 2012. I recently took my car to scan since I had the check engine light on.
