A grinding noise began to develop in the rear end of the truck. the noise was most noticeable between 30 and 60 mph. i took the truck to a toyota dealership for diagnosis and they determined the rear wheel bearings had failed. these bearings are sealed, require no maintenance, and should be designed to last the lifetime of the truck. this is a safety concern because a bearing failure could lead to loss of vehicle control and an accident. i have found a number of similar incidents reported on internet tundra forums, which indicates this is not an isolated problem.
While driving down the road the transmission has problems shifting into 1st and 2nd gear. the transmission is a little sluggish while shifting and in some cases even jumps while shifting into 1st and 2nd gear. have had it looked at and was told have to replace the whole transmission. i have a coworker who had some problems with his transmission on his tundra, and he ended up trading it in, because it could not be fixed. i have the paperwork from getting it checked if it is needed
Please refer to tsb 0160-11. toyota recognized that inferior quality parts were used as part of their emissions system and wrote this tsb as a remedy. the problem i have is that they continued to use the faulty parts beyond the 2011 model year cut-off in this tsb. my truck is throwing the same engine and emissions codes associated with this tsb. it also forces the engine into a "low power mode" greatly reducing the ability to accelerate. lastly, it turns off traction control which affects the stability of the truck. i have filed a ticket with toyota and from what i have read on the internet, i don't expect much help. the parts to repair this run over $1,000 alone. there are many owners having the same issue with the tundra, sequoia and some other models (on the 4.6l, 4.7l and 5.7l engines). the engine codes usually appear on startup (when the emissions device are supposed to kick in), but the low power mode kicks in while moving.
I see several other complaints here with my exact problem. the secondary air injection system relay and secondary air injection system switching valve. obd ii codes p0418 and p2442. my experience is the same as other complaints in that my truck is now permanently in limp mode and cannot be driven due to these known defective parts. on pre-2012 model tundras toyota has extended the repair warranty to 10 years/150,000 miles as this is a widespread problem. for some reason they will not include later year model trucks like my 2012 4.6 liter. this is a safety issue as the truck slowed severely in traffic and will not accelerate or go up any hill. cars behind me in traffic had to swerve around me. i was stuck dead at the bottom of a hill as these chronically failing parts shut down the vehicle's power. toyota customer care has denied my attempt to seek compensation or repair of these parts that they know are defective. the fix needs to be extended to all year model and engine size tundras as these defective parts exist on models past 2011. a side note, somehow these defects are reported to be affecting the vehicle skid control as that warning light comes on when these parts fail on most of the affected tundras.

I took my wife and daughter on a couple of runs threw the mud in our 2012 toyota tundra crewmax 4x4 trd. the runs were no longer than 2-3 minutes of fun with zero problems. i did not have time to run our truck threw a car wash. i planned on getting it washed the next day after work. on my to work the following day our truck showed no signs of problems until i entered the freeway and continued to accelerate. at that point of time i could "feel" the transmission was not shifting correctly . i called avondale toyota immediately informing them there was something wrong with my transmission. they set an appointment up for friday the 7th of march. i informed toyota that i would prefer to drop the vehicle off when i finished work because i felt like driving it would only cause more issues if any. today i received a phone call from avondale toyota informing the transmission "burned up" and is not under warranty even though our vehicle is under warranty. their warranty rep based his opinion on pictures, still dirty from going threw mud, and concluded the transmission was "abused" and toyota is not responsible for "abuse." i immediately went to avondale toyota and spke with[xxx] and the mechanic who looked at the transmission. the mechanic informed me that all fluid levels were normal, temperature levels are normal and no transmission codes were tripped. zero!!! a gear broke in the transmission and telling customers the transmission "burned" up is an easier way to inform customers.it is their assumption that i got stuck in mud and "attempted to rock the vehicle by moving the shifter back and forth from drive and reverse while i was on the accelerator." i informed the avondale that was not the case. i could of simply took our vehicle to the car wash, had it cleaned and contacted toyota and told them my transmission is acting up. lying seems the way to go these days. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr
Flex fuel models sold by gulf states toyota have an issue where the engine's computer thinks there is e85 fuel (or an alcohol concentration that is much higher than actual) in the system when there is normal 10% or less gasoline actually present. this can cause rough cold starts/idle, power loss, sudden rpm/power dropout, missing, and lessened fuel economy, etc. (different symptoms for different trucks). at this time there is no final fix and no available service bulletin. the only guidance at this time is to have your dealer see what alcohol concentration your truck is running and re-flash the computer if the readout is incorrect. dealer also states to not accelerate aggressively. i have service schedule on 3/9/13 to address the problem for the third time. i purchased the vehicle new on 11/23/12. *tr
