Tl* the contact owns a 2005 toyota tundra. when the accelerator pedal was depressed, the vehicle failed to respond. the vehicle was taken to a dealer where it was diagnosed that the air injector pump needed to be replaced. the vehicle was not repaired. the manufacturer was not made aware of the failure. the approximate failure mileage was 150,000.
Tl* the contact owns a 2005 toyota tundra. while driving 35 mph, the emission control failed and the warning indicator illuminated. the failure occurred twice. an independent mechanic recommended that the second air injection system be replaced. the vehicle was not repaired and the manufacturer was notified. the approximate failure mileage was 120,000.
Tl* the contact owns a 2005 toyota tundra. immediately after starting the vehicle, air began leaking from the air injection system and the check engine warning indicator illuminated. the failure occurred multiple times. an independent mechanic stated that the air injection system needed to be replaced. the vehicle was not repaired and the manufacturer was not notified. the approximate failure mileage was 126,000.
Loss of acceleration power. dealer quote $3,745 to replace pump/valve/driver assemblies. told by repair shop same issue as technical bulletin addressed on 2007-2010 tundras power issues. if true, seems a recall should have been required to repair 2005 year models. *tr
2005 toyota tundra. consumer writes in regards to air induction pump design flaws *tgw the consumer stated according to the mechanic's report, the second air pump, secondary air switching valve, bank 1 and bank were replaced. they were all clogged with insulation foam and stuck to the valve seats which kept the valves open. the secondary air inlet was also replaced, due to the hose being hard because of the heat under the intake manifold, which also contributed to the engine not being able to cool properly. further research about air induction pump design flaws on toyota vehicle revealed a nationwide problem affecting tundra's up until the 2010 model.
My 2005 toyota tundra has a leaking exhaust manifold. on the way home from the hardware store my new co detector went off indicating co in the cabin. i have contacted the dealer and the manufacturer and they refuse to repair. *kb
2005 toyota tundra. s10 appropriate handling- letter to the secretary from regarding toyota problems *tgw the consumer stated the oil pan was cracked on the side, the rack and pinion assembly and fan had to be replaced. the drivers side door was loose, the spring was sticking out of the seat cover. the consumer has since sold the vehicle. *jb
Air induction pump 2005 toyota tundra pump failure. defective design. *tr
Engine light came on. after having codes read, problem was identified as the air induction pump. the issue is that when this pump goes out, it puts the engine in a "limp" mode, which causes the vehicle to not have adequate acceleration to merge with traffic. this is a safety issue as drivers do not know that the "limp" mode occurs when this happens. needless to say, the replacement part cost over $1300. i would think a part of that expense should last longer than a little over 50,000 miles.
2005 toyota tundra experience electronic failure*cw the consumer stated the mechanical or electronic failure caused an accident as well as injuries. the consumer stated all he remembered was exiting the highway in evening traffic when all of a sudden, his vehicle rammed into the vehicle in front of him. the air bags deployed prior to the collision and he had no recollection of being able to brake. he also stated the engine failed in june 2009. the consumer was informed there must have been something wrong with the seams in the radiator. apparently, it blew out the bottom, which caused the instantaneous loss of the radiator fluid. *jb
Noticed liquid on ground underneath engine after driving. opened hood to discover antifreeze/coolant dripping from overflow reservoir which was full. coolant was extremely dark brown in color. took it to toyota dealer who completed flush, replaced sensor, and faulty radiator cap (torn gasket). *tr
The truck was brand new and only had 4,500 miles on it when the check engine light came on and the truck started acting funny. toyota said they were not going to fix it and i was never given a replacement under lemon law when this happened. i had just got the truck in october 2005 and in december 2005 it started acting up. i am a trained mechanic and i know this should not happen to a new vehicle. i want toyota to refund me the money i put down on the truck, which is around 8 grand. *tr
2005 toyota tundra quad cab. front end alignment problems, extreme pulling to the left and right, consistent rattling in the front end. control issues at 5 mph, extreme shimmering over 65 mph. recommended parts by service department knuckle sub assembly, bearings, ring hole, seals. vehicle loses power, and steering control, caused accident. manufacturer refuses to honor warranty and repair vehicle. problems began at 2000 miles, taken in at 5009 miles for service and reported problem, 4 attempts at repair with no success. *nm
Dt: when the engine is started cold it idles very high. when taking foot off brake or putting vehicle in gear it accelerates quickly. no accidents reported. also, no other problems. taken to dealer to inquire about this, dealer stated that this is normal. it seemed twice as fast as a normal vehicle in idle. when the engine is hot this problem goes away. *ak *nm
Long delay between depressing "drive-by-wire" gas pedal and engine responding. my 2005 toyota tundra has an electronic gas pedal. it's unacceptable behavior may explain some of the current "surging" people are seeing in other toyotas. this is a 100% software problem (i am a electronic engineer). description: when the engine is at idle, or even worse, when you are decelerating at idle power, and you increase the throttle position of the gas pedal, there is a nearly 1-second delay before the engine responds to the throttle input. if the driver, not sensing any response to throttle, applies more and more throttle during that one second delay, when the engine electronic throttle finally does respond it will immediately go to the highest throttle setting the driver was selecting, causing a huge lurching forward action of the vehicle. for example, if the driver applied throttle in this fashion: 0sec=5% throttle; 0.25sec=10% throttle; 0.5 sec=20% throttle; 0.75sec=35% throttle; 1.0sec=50% throttle. the engine's electronic throttle will respond like this: 0sec=0% throttle; 0.25sec=0% throttle; 0.5 sec=0% throttle; 0.75sec=0% throttle; 1.0sec=50% throttle. causing the huge lurch at 1.0 second. this has been especially dangerous while changing lanes during stop-and-go traffic in the san francisco bay area. please note that if i am running at partial power/throttle, this behavior does not happen, and the gas pedal response is proper. only from idle or decelerating. i have complained numerous times to my toyota dealer, to which the service manager finally replied to me "you think the tundra is bad... you should try driving the sienna! it's worse!" so apparently the folks at toyota know about this and think it's funny. i can demonstrate this defect at any time. i have changed my driving style to protect me from the vehicle's defect. *tr
