Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While commuting to work the engine light and traction control light came on, causing my truck to slow down, very slow. It would not let me accelerate and disabled my progress to around 2000 rpms. This could have been a very serious or a dangerous situation especially if I was towing a load or in a major traffic situation. Codes - 2440 and 2442 were the causes of this scary account.”
NHTSA complaint #11021153, filed 2017-09, 105,000 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.”

The truck will not easily accelerate beyond 30mph. This is caused by error code p2442 and p2440, from a known faulty part that Toyota refuses to replace.”
