Notes: A dependable pickup option that does have a slight history of frame corrosion. Even though mud looks cool on a truck, it's best if you run this through the car wash every now and again.

In November 2011, our 2003 Toyota Tundra was taken in to shepards Toyota in rockland, me where they sprayed "corrosion treatment" onto the frame to try and address their defective frame issues on this product (this was done under warranty). This "corrosion treatment" product failed and flaked off within a year. When we took the truck back to shepards, we were told that Toyota had changed to a different product, as they had found that the original "corrosion treatment" product they were using was failing. However, they would not re-do our truck, saying that they had met the "minimum federal requirements" by doing the treatment in 2011. We have recently been told by our mechanic that the frame will likely not pass inspection next year, due to the amount of rusting on the frame. We only have 100,670 miles on this truck, and had hoped to have a useable truck for many more miles to come. I contacted Toyota several times over the past two weeks, trying to get them to help fix this issue. Toyota is telling us that because they did the "corrosion treatment" in 2011, that they "met the minimum federal requirements" to address this issue, are under no obligation to help us any further, and will not do so. If the treatment had worked, then I would have no argument. Their "fix" was not a fix - in fact, within a year, they had switched over to using a different product, as they'd discovered that this original product was failing. Think of all of us who were being responsible consumers and getting our trucks in early for treatment once word got out about the frame issues, and who were given the treatment that was doomed to fail. It is so not fair. Our case number with them is 1404301535. During the work day, I'm most easily reached by E-mail. I am not at the home phone until after 4pm most days. Sincerely, heather jackson

The 2003 Toyota Tundra access cab truck is not compatible with the latch carseat system. The top hook on the truck is larger in size than the hooks on the carseats. It is impossible to install a carseat in either the right or left position in the rear seat of the Tundra. I complained to Toyota and the did redesign the 2004 Tundra to be compatible but did not offer a solution for the problem with the 2003 Tundra. My local Toyota dealership made a modified tether for my child's carseat with a larger hook attached that would fit the Tundra hook. Toyota as a manufacture did not provide a solution however.

I am a child passenger safety technician. I assisted a client today with the installation of a graco "cargo" child restraint model # 8487bel edom 08/31/04. In trying to install the seat in the passenger side rear outboard location of a Toyota Tundra access cab truck, I found it essentially impossible to secure the tether (top strap). The vehicle manual is poorly illustrated and the path for threading the strap behind the seat is impossible with the typical 2 inch hook type tether. Please review the manual & check the vehicle. I eventually installed the seat in the center with great difficulty using the instructions for the center tether installation. These instructions are really unacceptable.
