Fake Toyota Part Fail Warning

Here’s why something as simple as a fake Toyota gas cap can cause problems for your vehicle. Plus, find out where the common rust areas of a Toyota 4Runner are that you should keep an eye on.

When a DIY Repair Failed Because of a Faulty New Part

One of the lessons we’ve discussed in the past is that sometimes the correct repair is done, but the owner or mechanic is still left with a problem that won’t resolve itself when it should. Or is resolved, but reappears shortly afterward. In some cases, this is due to using an inferior aftermarket or counterfeit part to save money.
