I was driving down the road and the truck started to make a loud clicking noise. I was only a few blocks from my house. I went home, the truck wouldn't start again. My 2008 Toyota Tundra had an "engine failure" at 62000 miles. First they said $23,000 for a new engine. Then after months and many hours on the phone, they took the engine apart to find the problem. The dealer took pictures and sent them to Toyota. They said a valve or valve spring fell through and tore everything up. It needed a new short block and right head ($14,000). Toyota admitted 100% fault and said because the vehicle is 2000 miles out of warranty they will cover only 50% under " goodwill assistance" . So I bought the motor trend truck of the year ( brand new) and had to take out a loan for $7000 to get the engine fixed. I was out a vehicle for 4 months.
