Brought my 1999 LX470 into the dealership for what I thought would be minor to moderate repairs. I had moderate shake in the engine when stopped, some overheating issues when climbing high elevation, and clunky steering. The bill ended up being $9000 for a multitude of issues. I brought it in for inspection at another dealership 3 months ago for a coolant flush inspection among other minor wellness check, and they sent me off with no large issues. I know 301,000 miles is a lot, but 'm very confused how all these issues could appear now. I have been driving it in rougher areas, but nothing too ridiculous. The dealer is preparing to make an offer for it, because I can't afford the bill even if it was half the price. I'm linking the bill as well. Are any of these issues something I could ignore? Should I take it somewhere else for a second opinion?
