“I purchased a 1999 Toyota Tacoma in 8/2000. The vehicle had a blown engine that had been replaced and had been involved in a minor accident. I bought it from a local auto-body shop for $10,500 where it had been repaired. I have made my living with this truck and have put over 200 k miles on it with no major repairs. It has been trouble-free and I had no thoughts of replacing it. In october 2008, I took the truck to a Toyota dealer to be inspected for rust, on the advice of an friend. No rust perforation was found. …”
NHTSA complaint #10442858, filed 2012-01, 204,008 miles“I had a 1999 Toyota Tacoma. This truck was a 2wd with a 2.4 litre engine extended cab. The accelerator was always high. I got a few speeding tickets because of that. Even on small roads the RPM was unusually high. The mechanics also used to comment when they would do maintenance work on that truck. I lost this truck in an accident now. But please investigate this model also. Also the EGR valve on this trucks go bad frequently. Thank you for investigating Toyota. I thought I had a fluke bad Toyota truck, but it turns out that I was not alone. Thank you for your help.”
