Good Dealers (for service) in L.A. area?

Looking for a good Dealer in the L.A. area for service related items such as TSB work. I have only gone to the DCH Toyota in Simi Valley, and had them do the steering TSB, but the steering feels just as sloppy as before. Was hoping there is a better dealer out there so when I go in to get the rear leaf TSB done, they might actually do quality work.

 

About 50miles from LA, but I go to Crown Toyota in Ontario off the 10/15 fwy. They have ALWAYS gone the extra mile to help me and even replaced or fixed items not covered under warranty. They gave me a new battery after 2 years even though they proved that I ruined it, they replaced 2 tires after 12k miles, did my rear leaf tsb even though my truck didn't qualify... yeah they are great. And not just one or two but all the services writes go the extra step.

I've also heard that Toyota of Glendora is great too, closer to LA but I've never been there. Just whatever you do, do not go to the one in between those 2... Clairmont Toyota... major no no!

 

Thanks.
