Electronic Dashboard going haywire in 2006 Lexus GX 470
I've recently had this problem where the electronics on my dashboard start
going haywire on my 2006 Lexus GX 470. I recently replaced the battery,
and took this in to a mechanic who thought it was the speed sensor gone
bad. Unfortunately $390 later it didn't fix the issue. He thought it might be
the alternator? Any thoughts before I have to spend another $300 to get new
alternator?
