This is the second time that this has been happening. Noticed that it only happens when I use tiptronic (manual). First time I was driving hard then floored brake become light turned yellow. Few minutes later, a rotten, sulfur, egg smell came out of no where and my sister thought I passed gas (when I did not).
Second time that happened was when I dropped off my friend late at night, went on manual but this time I drove casually & normally and didn't go crazy. As soon as my friend got off, there's more of a burnt smell then with a hint of a rotten egg that took place in my car.
My car is 2009 and has only 83k miles in it. Read to a similar scenario online and seems like my catalytic converter needs to be replaced.
I worried that my car is internally bad, should I bring it back to Toyota (where I purchased vehicle pre-owned) for a diagnostic?
I'd appreciate any advises!
