Sorry for the new noise issues. But for other people, let this be a warning when you decide to let people you don't know work on your car. T10 tech or otherwise. Stealerships are structured to make more money the faster they work, which means they can never ever treat your car the same way they would treat their own. Each car repair has a set number of hours assigned for that job completion. Beat that number, make money. Take longer and lose money. This means they are incentivized to cram as many hours worth of work into as few hours of actual labor as possible to maximize revenue. Warranty repairs also need to be in and out asap. However, they do loose time and money if they have a 'comeback'. Which is why he's fucking with you now. They don't want it back cuz he'd be working for free.

This all assumes the tech in question was actually properly trained in the first place and gives a shit.

Ultimately, no one will care about your car as much as you do.

Worse come to worse, write a letter to Toyota Motor USA about your dealer. Or threaten to first.
