NHTSA Complaint #11703159 — 2022 TOYOTA TUNDRA

On Aug 1st I started noticing a slight shake in the vehicle on the way to work in the morning. I can best describe this shake or shutter like an imbalanced tire or a misfire. On the way home I noticed that the shutter was only present around 1,100-1,300RPMs while under gentle acceleration. About 6 miles from home I noticed the engine would bog down from time to time and shortly after I could hear a slight metallic sound. It was not until I got into town where I was set a slower road speed that I could clearly hear that the metallic sound was a rod knock. I have the hybrid model of the new Tundras, and on that last bit of stretch getting home in town the truck never threw an error or even understood that it was having an engine failure. Towards the end it would kick the engine on and off trying to flip flop between hybrid/EV mode and ICE mode. And some of those instances I think the engine was stalling out. Mine engine never seized up fully, but if it had I question whether or not the ECU would have understood this to disengage the engine from the drivetrain to propel itself only on the MG. As of today (12/5/25) my truck is still down at the shop because of this engine failure. Toyota originally covered a short block replacement under warranty. After the dealership assembled that new engine they are having nothing but one problem after another. After about a month to a month and a half of fighting the new engine Toyota's FTS got involved, were they ordered the new engine to be disassembled for investigation. They found that the new engine had completely destroyed itself, and they claim the cause was from the technician not applying assembly lube on the camshafts. After that Toyota blamed the technician at the dealership and refused to help fix my truck (which is well within the drivetrain warranty). I now have an open arbortation case with the NCDS for this.
