2006 Toyota Tundra Owner Comments

Tundra 8-cyl

  • Automatic transmission
  • 20,000 miles


The contact owns a 2006 Toyota Tundra. The contact was driving 30 mph and there was an abnormal increase in engine rpms causing the transmission not to shift correctly. She depressed the brakes and the tachometer increased to 2 and would not decline. In addition, when she attempted to shift into reverse and released the brakes, the rear tires began to spin and she crashed rear-end into a boulder. The rear bumper was damaged and there were no injuries. The dealer stated they were advised by the manufacturer not to diagnose the vehicle. The vehicle was neither diagnosed nor repaired. The contact stated that the vehicle has had three transmissions since purchase. The failure mileage was 20,000 and the current mileage was 53,000. Updated 11/9/10 the consumer stated the transmission had to be replaced three times. She also stated there were times when the vehicle would just take off at a high speed when the accelerator pedal was tapped lightly. When the vehicle was started, the engine would race extremely high. The high idle would also effect the way the vehicle shifted into gear. Updated 11/12/10 the drivers side has a grommet and the floor board has a grommet, but there is no hook to hold the floor mat in place. Also, the transmission has been replaced three times. Updated 11/1/610

Tundra 4WD

  • Automatic transmission
  • 36,000 miles
Toyota Tundra 2006 double cab 4WD automatic transmission. I was 4 wheeling and stopped behind a polaris, by approximately 5 feet. I was in drive and 4WD and brakes applied. I stopped because the polaris had stopped. All of a sudden with the brakes applied my Tundra lunged forward at a very high RPM crashing into the polaris. At that point I put the transmission into park and shut the engine off. Had I not responded with the action I took I would have shoved the polaris with 2 people into a very deep wash. Needless to say there is a great deal of damage done to my Toyota. The Toyota has major damage to the front end. Had I not taken the action that I did, we all would have ended up in the deep wash with major injuries. When I arrived home I immediately called tim's Toyota in prescott Arizona where the vehicle was purchased. The 2 people that could help me with the situation were not available so a call to them tomorrow will be in order. I have not contacted my insurance as yet as I feel that Toyota is the responsible party for the accident. I had written to you quite a long time ago regarding the cruise control surging to 5000 RPM's when approaching even a minor incline. So I don't use it anymore. I am afraid to drive my truck into my garage for fear that the truck will lunge forward, only this time it will crash into my HVAC and water heater, both are on propane.

Tundra 4WD 8-cyl

  • Automatic transmission
  • 3,500 miles
I was driving North out of phoenix Arizona on I-17 just past black canyon city, with my cruise control set at 75 mph. There is a very long hill going North to sunset point. Prior to approaching the hill I canceled the cruise so that the transmission wouldn't hunt gears. I drove up the hill at 65 to 75 mph (no cruise). When I made the top of the hill at sunset point and leveled out, I accelerated the vehicle to 75 mph and hit resume. The engine raced to 5200 RPM. I redline at 5700 RPM. The transmission did not follow suite. It was as if I was in neutral revving the engine. I immediately canceled the cruise and drove a mile or so without cruise, then decided to try it again. Everything worked normal. I have been in contact with my dealers service dept. And they are baffled. They have not looked at it as yet due to their schedule. As soon as they can get me in they will. They did say that there should have been a check engine light, but there was not. They are hoping that the onboard computer recorded it. Not only is this a major safety hazard, but it could have caused my engine to blow up. I'm not sure what reaction my wife would have had. She drives all the vehicles we have and they both have cruise, yet she is not that familiar wit RPM's and redlines and the issue that follow. When I have allowed the cruise to pull me up an incline it usually drops 1 or two gears and the RPM's are around 3000 to 3200. This I consider normal. I had a 1999 Toyota Tacoma with a six cylinder engine and cruise, so I am very familiar with the system. I purchased the vehicle from tim's Toyota in prescott, I also brought to their attention a noise that I heard in the right front suspension and they are going to take care of it under a new recall that has not even been sent to customers, nor was the service dept aware of it.

Tundra 8-cyl

  • Automatic transmission
  • 10,000 miles
This filing is in reference to my 2006 Toyota Tundra SR5 V8 4.7 ltr 10,000 miles. For the past few weeks of driving the above referenced vehicle I started to notice a knocking metal sound under the center console when accelerating and braking... I took no immediate action as I found it to be a very light sound. After a few more days of driving the knock became more noticeable I was more alarmed, when I got home I got under my truck with a flashlight and started to take a look around, after careful inspection I found that 3 of 4 12mm hex bolts on the automatic transmission mount/ crossmember were missing further more the case was that the rear transmission mount located near the driveshaft were loose enough that could be moved with minimal strength with my hand I was able to recover 1 bolt that fell into the crossmember along with a plastic retainer. I quickly tightened the loose bolts and realigned the mount took the truck out for a quick test drive and the sound stopped totally, the next morning I contacted my local Toyota dealer and purchased 2 new hex bolts that came out to $ 3.40. After this U can say that all is now well, I believe this should be looked into as there maybe other similar units out there with the same issue, this could cause major damage to the vehicle and also possible inflict an accident.
