Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Tundra had electrical fault in transmission due to wiring harness corrosion. Tundra will drop our of gear while driving and reengage violently. Toyota has refused any assistance and I am unable to repair due to national backlog on necessary parts. My Tundra was part of the rust recall a couple years ago which was never properly rectified and I believe this is a continuation of that problem. Transmission issue seems to occur mostly at speeds up to 45 MPH.”
NHTSA complaint #11172581, filed 2019-01, 135,000 miles“My 2005 Toyota Tundra suddenly lost power on the highway and started to buck. I was able to pull over but had to have the truck towed. The problem was a corroded 15 pin connector plugged into the driver side of the trans. I found that many other people are having this problem at around 80k miles. There is a nation wide back order on the part to fix part of this problem.”
NHTSA complaint #10323024, filed 2010-03, 81,000 miles“Since my vehicle hit about 50000 (the date below is an estimate) and it is at 79900 now when I park and turn off the ignition and remove the keys and roll up the windows and lock the vehicle and leave it a vast majority of the time the power drivers window rolls itself down at some point between two minutes and many hours later allowing for anyone to tamper with any of the trucks interior safety devices and leading to possible theft of the vehicle, its parts and contents. …”
NHTSA complaint #10838168, filed 2016-02, 50,000 miles“Sitting in traffic, the engine revved up by itself on my 2005 Toyota Tundra sr5 v8. Problem was abated by turning engine off and restarting. This problem resulted in a mil error that side b of the engine was running lean. After completing an analysis of the problem, the findings are that the oxygen sensors are not responding to specification. It is my firm belief that the firmware on the ECM does not self check for runaway conditions.”
NHTSA complaint #10318156, filed 2010-03, 92,500 miles“I had a check engine light that came on which, after checked by a computer, was determined to be part number 1445 (p1445). I researched it out and discovered that this is a common problem with the Toyota Tundra 2005 models, yet Toyota would not cover the cost nor did they care unless I was willing to pay for it. P1445 is for the secondary air injection system valve #2 stuck closed. Is there any way I can be reimbursed by Toyota for having to pay for the replacement of a part that many have had the same problem with? …”
