2006 Toyota Tundra Access Cab SR5 4dr Access Cab SB (4.7L 8cyl 5A)
06 Tundra lacks refinement
 The SR5 has a particularly poor interior both materials quality and comfort level.  The steering wheel is about 1 to 1 and a half inches offset from the center of the seat mostly an annoyance.  The CD player was unable to play the disk that I routinely used in my other, old vehicles.The accelerator pedal is way too touch, a hallmark of this age of Toyota, it takes concentration to leave a light smoothly.  Between the touchy accelerator and the light rear end it was hard to deal with any slick pavement and it tended to wander on dirt roads.  The seat belt retraction lacked a decent return spring, the previous owner was not careful and as a result the belt tang had gouged the door sill multiple times from being caught when the door was closed.    The engine is powerful but has a groaning sound, not pleasing at all, more like it is straining.  At 10 years old and 40k miles the dealer informed me that it needed a timing belt every 8 years or 100,000 miles and while they are in there they like to replace the water pump since the Japanese engineers put the water pump behind the timing belt.  That was a $1200 job.  The water pump was leaking at 40,000 miles.  My Dakota water pump lasted 120,000 miles and 14 years.  When people brag about getting high mileage from these Tundras of this era be aware that according to Toyota you have about $1200 in maintenance for every 100,000 miles.  I inherited this vehicle and traded it in within 2 years for GMC pickup.
