my IS250 has ran great since I purchased it almost 5 years ago. I was driving it the other day and it suddenly just shut down. I had to have it towed to the dealership. They told me I had to replace the engine because it locked up. Is that common? Shouldn't have have gotten a warning there was an issue. I take my car to the dealership for all oil changes and nothing on my report showed any issues. I am very timely with my routine maintenance. Help.

 

sounds like there's more to the story. engines don't just lock up for no reason.

 

Could you restart it after it shut down? Did you have any check engine lights? Flooding in your area?

 

Definitely not common, I would go so far as to say it is quite uncommon.
