Problems with 2008 Toyota Tundra ENGINE AND ENGINE COOLING

My 2008 tundra suddenly showed multiple dash lights when i started it. it ran rough, tried code reader on it ,again multiple codes at once. every item can't bad all at same time. the main problem was air pump failure, have a feeling it's associated with exhaust problem. truck has been ticking since about a month after i bought it brand new, i just assumed that's the way it was since it quiets after warms up. turns out manifold is cracked by the pump. of course warranty is up. after reading online seems like a lot of people are having same problem. have had it several times over the years for oil changes etc. . the dealership's know there is a problem and ignore them. i have two other toyota cars and this is the first toyota truck i've bought . toyota we'll have a bigger problem when go back to buying the chevy,ford, dodge. they were buying before they came out with full size tundra. get your act together toyota or you will lose a lot more money and respect than what the recall will cost. *tr

My truck was parked for 3 days, then when i started the engine all of the traction control lights started flashing, the check engine light remained on steady, and 4lo light flashed, truck would not travel over 30 mph and became very sluggish. this has happened three times in one week, and disconnecting battery for a few minutes cleared the problem. local dealership said the problem is a "failed actuator ecu assembly failed communication c1201". cost of repair is $2,280.41. warranty does not cover repair because this part is only covered by the 3 year/36000 mile warranty. drivetrain warranty does not cover this component. this is a safety concern because when this problem occurs while driving there is no warning and could result in a multiple vehicle accident. the only other part that causes this problem is an air pump assembly which is now required to be covered by toyota for 10 years or 150,000 miles. very discouraging to own a truck less than five years old with 55,000 miles and requires a $2300 repair. *tr

I was driving down the road and the truck started to make a loud clicking noise. i was only a few blocks from my house. i went home, the truck wouldn't start again.my 2008 toyota tundra had an "engine failure" at 62000 miles. first they said $23,000 for a new engine. then after months and many hours on the phone, they took the engine apart to find the problem. the dealer took pictures and sent them to toyota. they said a valve or valve spring fell through and tore everything up. it needed a new short block and right head ($14,000). toyota admitted 100% fault and said because the vehicle is 2000 miles out of warranty they will cover only 50% under " goodwill assistance" . so i bought the motor trend truck of the year ( brand new) and had to take out a loan for $7000 to get the engine fixed. i was out a vehicle for 4 months. *js

The engine check light came on and the engine went into limp mode, which reduces engine power making it dangerous to drive. the check engine light came on from the emissions valve set failing. when repaired by dealer they also discovered a cracked manifold. this emissions valve set failure seems to be very common on 2008 tundras and is very expensive to repair. to my surprise the manifold was cracked and that is a very expensive repair and may have contributed to the emissions valve set failure. toyota should recall their emissions valve set and redesign it so it does not fail, and is less expensive to replace, and finally they should not program the engine to go into limp mode if this failure occurs, as it can cause you to lose power while driving in various conditions that require power to get off the road safely.

Emissions valve and related pumps failed causing a significant loss in power. this happened when traveling on the highway in upstate vermont. suddenly my truck lost significant power, and would rapidly decelarate everytime i approach a positive grade in the road. several times during the trip i slowed down faster than cars behind me expected, and the brake lights did not warn them as it was due to the truck losing power, and not me braking. in addition due to the location i was at i was unable to locate a dealer for several miles. when the codes were pulled for the service engine it appeared as code p2442 (secondary air injection pump system switching calve stuck open bnks) *kb

Truck went into "limp" mode and the vsc, check engine light and the "traction" light all came on. took it to autozone to get a read out and it had a p2442 for a subaru, but was figured to be the asv (air switch valve) or the aip (air induction pump) on bank 2. considering that my truck is out of warranty with 62000 miles and all the forum and websites that i have been to that told me it would cast any where from 1000 to 5000 bucks to fix, i checked it out myself. the asv on the driver side has a metal plate that is broken and is keeping the valve opened. i have called a dealer and they told me they have no clue when the parts could be in because of the tsunami in japan. i am very upset as to this issue as i am not able to bypass the it and get my truck running correctly. toyota needs to step up and make a recall on these pumps and valves. i was told that one of the reasons for the issues is that water gets in the pimps. i cannot see how water is getting in these pumps and valves as they are enclosed. this is a design flaw and needs to be rectified. *tr

Check engine light, vsc light, and 4lo light illuminated while driving. response of engine became very sluggish - described as "limp mode". dealer diagnosed failure of air induction pump. *tr

Tl*the contact owns a 2008 toyota tundra. the contact was traveling 65 mph when the check engine light illuminated and the vehicle began to lose power. the contact could not accelerate pass 35 mph. the vehicle was taken to an authorized dealer where the codes were cleared and the air filter replaced. the failure occurred again and the dealer referenced a technical service bulletin regarding the filter. the current and failure mileages were 71,000. updated 4/4/11 *cn

2008 toyota tundra code# p2443 air injection system switching valve stuck closed bank 2. truck went into (limp mode) causing little power in heavy traffic. toyota dealer says min. $2000 fix for two pumps or a switch valve .lot of people with same problem, needs to be a recall. *ln

I have a toyota tundra 2008, after the dealer change the a/c cabin filter start a wet rag smell inside the car( mold smell) , this problem started a year before, when you used the a/c on max or recirculate the smell is less but when you use on vent only or air from outside smells a lot, has been past already a year and the dealer dont want to do anything about it even that i have a platinum toyota care service plan. now all my family are experiementing all kind of allergies include hay fever_type symptoms, such as sneezing, runny nose, red eyes and skin rash. the dealer had change the a/c cabin filter twice but the problem still there. we think that theres mold on the a/c system. they said that probably is not condensating the water so well or is letting the outside water comes in to the a/c system which probably is a a/c design problem. *tr

Code p2440 , secondary air injection valve stuck in open position. air induction pump, *tr

2008 toyota tundra. while driving at 65 mph, i had a air induction valve fail all of a sudden which caused my vehicle to suddenly stall into limp mode. i know this part has to do with emissions but how it caused the vehicle to respond when it failed if very dangerous. i was in heavy traffic and this sudden switch to limp mode caused me to basically loose control for a few seconds in bumper to bumper traffic. it was very dangerous as the vehicle suddenly dropped to about 35 mph with no control . traffic was swerving around me and honking their horns as my vehicle suddenly dropped from 65 mph to 35 mph. i understand parts will fail periodically but the way the vehicle switches to limp mode when this particular problem occurs needs to be redeveloped and fixed or some serious accidents are going to be the result. i have found that this is a more than common occurrence with toyota tundras in the 2007 and 2008 years. thanks for you attention to this matter. *tr

Tl*the contact owns a 2008 toyota tundra. while driving approximately 70 mph the contact stated that the vehicle shifted into limp mode. he experienced a brief lost of power and the check engine light, vehicle stability control and four wheel drive low lights illuminated. the vehicle was towed to the dealer. the dealer replaced two air injection switch valves in april 2010. the failure occurred again on january 31, 2011 and the vehicle was taken to a local mechanic who cleared the code. on february 12, 2011 the failure recurred, and the vehicle was taken to a second dealer. the dealer advised him that two air injection switch valves and two air pumps needed to be replaced. the vehicle was in the dealers possession when the complaint although the contact had authorized the repair. the vin was unavailable. the failure mileage was 135,000 and the current mileage was 180,000.

2008 toyota tundra 4wd 5.7l failure began feb of 2010 truck entered "limp mode" and was taken to dealer for diagnostics. problem determined to be "bank 2 valve stuck open for secondary air injection system" on my vehicle. truck has entered in and out of limp mode consistently for up to a week at a time since issue surfaced. during limp mode vehicle cannot accelerate properly and is limited in power and speed, creating many dangerous situations especially involving highway travel. for example, vehicle often cannot accelerate over 50-55mph solely, and i have even become trapped on an interstate at 26mph pulling a trailer. toyota has failed to accept responsibility for problem and denied my claim regarding issue and defect causing the situation. *tr

The problem with my tundra concerns the engine. three times since march 2009 the check engine light has come on. each time i have taken it to the dealer and they agree there is a problem however, the problem is intermittent and they can't duplicate the problem. the problem according to the dealer is a sticking valve in the engine component. the one time i did get it to the toyota dealer in south dakota, when the problem was still occurring, i was told they didn't have the part so they couldn't fix it. when this problem occurs, the engine on occasion has hesitated and almost caused an accident. this was explained both to the dealer and the 'consumer rep.' (compliant 0911112241). i was told by the consumer rep. not to worry, if there was an accident the problem was documented. i was also told their tech rep was working on the problem and would call me back. that was seven days ago and counting. in summary, the toyota warranty appears to have very limited valve, the consumer rep. is window dressing, and your safety is optional. *tr

Engine turns off going down the road and then starts up at full throttle. all the lights are flashing on the dash including the 4 lo light. i have been dealing with this issue since the truck had 10k on it and now it has 42k on it. *tr

Tl*the contact owns 2008 toyota tundra. the contact stated that when the weather was humid, the check engine light illuminated. the contact stated that he was driving 5 mph when the check engine light came on. the check engine light would come on for a week at a time, then it would go off for a couple days, then back on 3 more times throughout the day. the owner took the vehicle to the dealership for testing. the dealer said that the computer was not showing a code so there was nothing that could be done. the failure mileage was 5,000. the current mileage was 13,5000. the consumer stated the transmission would hesitate during take off as well as during cold temperatures and the engine made a rattle sound. the radio would come on and change stations by itself. the consumer stated the accelerator pedal became stuck even before a recall was issued. the blower motor did not always work properly, the re-circulator would shut off by itself even if the button was held down for 3 seconds. updated 04/20/10

Tl*the contact owns a 2008 toyota tundra. at 26,787 miles, the contact heard a knocking sound coming from the motor. he took the vehicle to the dealer and they stated that the noise was normal, and was coming from a piston. when the motor is cold, the piston strikes against the motor cylinder wall. the manufacturer stated that all 5.7l engines had this defect and offered to extend the contact's warranty. they further stated that it would take much effort to correct the defect. the vehicle has not been repaired. the failure mileage was 25,000 and current mileage was 27,000.

Vehicle's engine failure do to very poor design and engineering by toyota on oil filter cap assembly #1562038010, toyota tundre 2007/2009 model with v8 -c- 5.7engine. the pertorated steel center tube will come off in the old oil filter and will fail by collapsing in fairly short order and total engine failure. $22,000 to 30,000 for new engine. *tr
