Hello everyone, Merry Christmas!My 2017 lexus is200t has a strange problem after tonight. System errors occurred:
-pre-collision system malfunction
-blind spot monitor system malfunction
- antilock brake system malfunction
- lane departure alert malfunction

I restarted the engine, errors are gone. After about an hour of driving, they reappeared and did not go out. Has anyone had anything similar? Or know what could be the reason?Thank you for any help.

Answer

Get it scanned, these errors will pop out with about any error codes and are mostly unrelated.

a bad alternator sending off all your lights perhaps?

There's no way of telling just by the dash lights as to what's causing them. If I had to venture a tiny guess, there's something specific in the ABS module that's turning on all the other lights, as the car doesn't think it can control itself so it turns off driver assistance systems, but I could be wrong.

Guys, a simple O2 sensor going bad will trigger all those warnings. All those things go off pretty much automatically when there's a check engine.

Get it scanned, you will know for sure, the internet cannot scan it for you!
