  • 50,000 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. In addition whether the window rolls itself down or not the vehicles alarm will sometimes sound when there is nobody near the vehicle and after having it checked out by a local Toyota dealer who had no idea what is causing it nor how to fix it and sent me away with problem unresolved I have to open the hood every time I park and manually unhook the negative lead to the battery which further exposes me to potential injury either from battery malfunction or engine malfunction due to the constant disabling and reenabling of power to the entire vehicle and to my person due to being struck by another vehicle by standing on front of my truck with my view of my surroundings blocked by the raised hood and other drivers view of me in that unexpected location as I am in large part blocked from view by the raised hood. This has been witnessed by my mechanic and his employees as well as family members

Secondary injection pump trigger a limp mode which is extremely dangerous on the highway. Toyota has extended the warranty on all vehicle except the 2005, 2006, 2007 which have the exact same air pumps installed. This repair is costing Toyota owners in excess of $3,000 with vehicles having having less the 100K miles. This is obviously an emission issue that Toyota should address, the U.S. has made VW responsible for there shortcomings I think Toyota should be held accountable.

The connector on the cable from the ECU to the transmission failed due to corrosion. This causes the truck to accelerate from a standing stop in a manner where the transmission slams in and out of gear. Thankfully this didn't occur when pulling out on a busy street. The situation is dangerous. The truck already had a frame recall due to corrosion. This issue is similar and represents a design flaw with dangerous consequences.

Toyota has extended its warranty for the air injection pump and air switching valves on 2007-2010 Tundra. The extension is for 10 years or 150,000 miles from first use. I have a 2005 Tundra that has a failing air injection system. I am within 10 years of first use. The truck has the same air injection system as the Tundra within the warranty extension, but Toyota refuses to honor the warranty extension on my truck. This is a $4000 fix and the truck is unsafe to drive in the current state.

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? this is clearly a faulty part put into the 2005 Toyota Tundra and Toyota should be required to pay for it's replacement.

The contact owns a 2005 Toyota Tundra. The contact indicated that burning wires fumes emitted from the front of the vehicle. The contact stated that the failure had occurred before and the heat from the fire prevented him from lifting the hood latch. After inspecting the vehicle, the contact noticed the fire was burning on the floor of the front drivers side. The vehicle was destroyed. The contact did not sustain any injuries and was able to exit the vehicle. The vehicle was to be further inspected and diagnosed by the manufacturer. The manufacturer was notified of the failure. The approximate failure mileage was 100,000.

My truck has 2 parts that have gone bad, the air injection pumps and air switching valves. Toyota issued a warranty policy bulletin regarding these parts on Tundra models 2007-2010 and 2008-2010 sequoia models. My 2005 Tundra was not included in this customer support program. However, my truck has the same part that is on the 2007-2010 Tundra and has malfunctioned. This is an issue that Toyota has been aware of and that was the reason for the warranty enhancement for these parts on the 2007-2010 Tundra. Toyota has refused to include the 2005 models in the same customer support program to replace these defective parts, they have said they would pay only half of the costs to replace them. If its the same part as the 2007-2010 that Toyota knows were defective, then why not include all model Tundra and sequoias that have these parts? the warranty enhancement was extended to 10 years/150,000 miles. My 2005 has approximately 121,000 miles and was checked by my local dealership whom reported the problem to me and stated what the defective parts were and they also gave me the information regarding the customer support program(ztq). Please give feedback to whatever you may find out. Thank you, [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Unintended acceleration occurred when proceeding through and intersection at about 4:50 pm 01/04/2011. Brakes were applied but the power of the Toyota tunda SR5 V8 engine had enough power to accelerate unintended to approximately 50 mph even tho the brakes were applied as had hard as it could be applied. The truck centered an oak tree in the blvd approximately 150-200 ft from the intersection. The truck was totaled by my insurance company. Only the driver was in the truck and no other vehicles at the time of the incident. The driver suffered a broken left arm at the elbow which required surgery.

The engine shut off while I was driving on the road and making a left turn. I realized the engine shut off when I pressed down on the accelerator and nothing happened. The radio was still on the headlight and horn worked. I switched the battery out with a new one. The engine would still not start. I would turn the key and only the radio would turn on. No noise or response from the engine could be heard with old and new battery. Vehicle was towed to Toyota dealer, they replaced what they said was a blown out ignition fuse. As I drove out of the parking lot from the Toyota dealer the engine shut off again exactly how it had occurred before. I was less than one block from the dealer when this happened. It is currently at the Toyota dealer.

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.

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.

The contact owns a 2005 Toyota Tundra. The contact stated while driving at 25 mph the ABS light would flash on the dash board indicating that the brakes need to be serviced. The contact took the vehicle to a local mechanic to have the brakes serviced and the local mechanic could not find a issue with the brakes. Also the contact stated that the air flow button that controls the air inside the vehicle is malfunctioning. The contact feels this vehicle has a serious electrical issue and needs to looked at by the manufacturer. The failure mileage 6,000.

Tundra 8-cyl

  • 82,450 miles
My Toyota Tundra 2005, V8, 4.7L, 4X4(83,000 miles) lost its transmission power while driving on the highway and the check engine light came on. The transmission power came on and off all the way home. Lunging each time it dropped off and came on. I brought it to the dealer who told me I needed a new transmission at a cost of $4000. It was displaying P0986 code. The next day brought it to a transmission shop. They found that the wire connector (15 pin) that goes from the transmission to the ECM was corroded and the pins were broken and not making contact. Its design is clearly defective. It is not protected and is located in a place where it is exposed to all the salt and water resulting in the pins being corroded. Information communicated from the computer to the transmission and back is interrupted or inaccurate. I found this information on a website at the same time the independent transmission shop discovered what the problem was. The following site describes the problem very clearly with pictures and descriptions: www.techno-fandom.org/~hobbit/cars/tundtran/ I contacted Toyota. They gave me a run around with only frustration and stress. I see this problem occurring with all these trucks in any part of the country where it is wet. I feel Toyota should pay for the fix and not me. It is a major problem and causes unexpected power lose or transmission failure when driving. Please let me know asap if you want the old part after the new one is installed. It should happen in a few days.
