“The clutch on my 2003 Toyota Tacoma became jammed while trying to shift in the middle of an intersection. The bushing where the clutch pivots dislodged and jammed the clutch so it was unable to be depressed. A car was coming straight into the side of my vehicle when I stomped on the clutch as hard as I could, breaking the bushing and letting the clutch depress. If I had not acted quickly it could have been a fatal accident. This was on a highway intersection. …”

“Vehicle loses power unexpectedly and is inconsistent. Has happened before to me and many, many times by others with the same vehicle. A poorly designed/engineered accelerator pedal position sensor appears to be the issue. Toyota has been notified by me multiple times but refuses to acknowledge this serious flaw in their vehicle. Most recently, I was nearly rear ended when on the freeway, the vehicle suddenly lost power. Fortunately the driver behind me was conscious and was able to make an emergency maneuver to the other lane. Someone will die from these problems! …”

“On june 11,2010 I was changing the anti freeze in my 2003 Toyota Tacoma.the vehicle was in park and running to warm engine to open thermostat to get more coolant from the lower block . Well I decide to boost the engine speed by manually moving the throttle .to my surprise my truck lurched back before coming to a stop I check the shifter it was still in park .but a further exam the vehicle stuck in reverse and will not go into any forward gear. I m' going to check to see if the linkage needs adjustment everybody I talk with said it was not suppose to move unless the brake was applied first.”

“Truck always pulled to the left since new, took it in to Toyota dealer 4 times, they said nothing is wrong with it. At 21,000 miles I heard a bad noise coming from the differential, I pulled over and removed the fill plug only to find no oil in it.so I put in 4 oz. Short of a quart of 80w90 gear oil. (pulled to left because a wheel bearing wasn't getting and lubrication). Returned to dealer, they said we can't find a leak, 50 miles later I pulled the fill plug and found the oil to be black as can be with metal in it. Dealers answer is to come back when it breaks. …”

“After approx. Putting 5,000 miles on my Tacoma 2003 double cab, I started noticing when normally bringing the vehicle to a complete stop, there is a cluncking sound from the rear end. The harder you stop the vehicle the worse it gets. It's like getting slightly rearended by another vehicle. If it doesn't make this cluncking feeling and sound as you come to a stop, it will do it once you let off of the brake pedal to idle/roll forward to advance at a traffic light, stop sign, etc. This appears to be getting worse as I continue to drive the vehicle which now has 24,000 miles on it. …”
