2010 Lexus Navigation goes into freeze-up

When you get on a freeway with mulitple exits, it is supposed to calculate the time to the next exit. It goes into some sort of overload condition and anything that has to do with the computer that operates the navigation and almost everything else on the car goes into a mode where it will only respond after a minimum of 30 seconds up to a minute.

The foreman at the dealership called Lexus last week but no answer yet.

The #1 most reliable car sold in America is slipping fast.

    First off, understand, car manufacturers don't make their NAV systems, this one is supplied by DENSO Corp. Nav includes GPS tracking and an info disc and an onboard computer so it's not always a simple fix... and this is the latest generation of NAV with a ton of new features. I work in the industry TOYOTA/ LEXUS side and sometimes we end up with a seldom occuring problem, in your case on a fresh system but I'll gladly dig up info for you.... If you can clarify with a more specific description on the 30 second to 1 minute overload scenario, I will try to replicate and give you feedback via a master tech who is a good friend. Not sure if you mean the screen blanks out, or the recalculation doesn't update fast enough, etc... You can also try posting specifics on the LEXUS owners club forum... clublexus.... It is Very informative Don't let this sour you on the ownership of a fine vehicle. Remember you got from A to B before you had NAV. You will get this solved and LEXUS will prove your decision a wise one....

    sounds like the nav is not set up correctly. is the "avoid toll roads" preference selected in the set up catagory?

Please keep pushing lexus on this issue. the lexus engineers will figure it out and that will help the rest of us down the road. if your dealership does not go out of its way to help you with this then you need to complain directly to lexus customer relations.

Ive replaced my fuelcap, 2 times I had my engine light come on and each time the computer said it was the gas cap, after the 3rd time it went off I relized I have drove it and no problem until I exited of...


The light actually says the gas tank purge system is leaking, not that the cap is really bad. It could be the charcoal canister, vacuum hoses to it, the purge valve leaking, etc. Check out the whole gas tank venting system, not just the cap. That is just shorthand for the whole system.

My 2010 Lexus RX350 Navigation System is responding VERY SLOW!


If Lexus can't fix this there is nothing anyone here can do for it. Anything that can be done needs the proper scanning and reprogramming equipment only Lexus has. Being that the car is new when enough people complain about this they will come up with a fix, Their may be a recall on it in the future. But for now your going to have to live with it or trade the car in. I know you did'nt want to hear this but but if some yahoo directs you wrong it will cost you hundreds just to get the programming back to the way it is today. Some navigation systems if you disconnect the battery you will have to go to the dealer to get them to reprogram it. Use lots of caution when guessing. New cars are not made for the average back yard mechanic to touch.
