Example complaints

“Toyota has developed what is becoming an infamous oil leak on their 5.7 v8 engines that is coming from the camshaft tower (camshaft housing sub assembly). Apparently in production they use a silicone where this attaches to the head and in many cases they did not get enough silicone. Research has shown me that many, many of these have this issue and that when the vehicle is fairly new that Toyota will stand behind it in limited cases. My vehicle has 150,000 miles on it so they will not do anything to stand behind it and claimed to not be aware of the problem. …”

Since the update, my vehicle makes a loud noise when turning the engine off and then a thump sound. Was told that the noise is coming from the air injection pumps that were affected from the doe update. Toyota will not give me any documentation on the recall for my vehicle that affects the emission control ejector to fail and the vehicle going into fail safe mode. Toyota representatives are telling me that the noise is normal and is suppose to be there. …”
