dude i tried disconnecting the negative ...didn't work for me . took it in to the dealer + free wash! probably an hour wait. It was covered by factory warranty . it was 36dollar on the hand receipt but it should be free. if don't want to wait to long opt out of the wash should be out 15-30min.

 

I disconnected the negative end of the battery for about 7 mins. Reconnected and started my ES300h 2016. The system rebooted after the update and everything was back to normal. Turned off the car and restarted, no issues. Works as normal.

 

I disconnected the -neg terminal from the battery for about 6 minutes and everything is back to normal. I'm correcting my self. I didn't loose any info.

 

Did the fix on my GX & my next door neighbor's GX (saving her a scheduled trip to the dealer tomorrow). It wiped out all memory settings for everything except radio presets.

One thing It also did was it forgot my location for the navigation. For me, it thinks I am 2 miles away. For my neighbor, it thinks she is in Florida (we live in Atlanta)! I used the calibration tool to move it, but I did not do this on hers. Will the navigation eventually figure itself out and reset to her actual location after driving it around for a while, or do I need to go into the calibration settings and adjust hers too?

 

I disconnected the "-" terminal on the battery for about 10 minutes then put it back on. Everything goes back to normal. Thanks guys!!

 

diconnected the batter, left it like this for a good 1 hour.
reconnected, everything works fine

 

Stopped by the dealer today for our 2015 GX460. Was in and out in about 30 minutes, there were about 10 other people sitting in same area discussing this issue. One lady had a RC350 that she bought 6 days ago experiencing this issue lol.

They reset the system and now the car is functioning like normal.

 

Is it us (wife and I)... does the Navigation/GPS looks different?
Sucks!! We liked the big view on the screen. Not an option anymore

 

Thats at 300ft




And the max 150ft

 

I never experienced the NAV failure in my 2015 GX as I had not been driving the car. On Thursday, after reading the posts about the problem, I took the car out for a drive. Immediately after start up, the info screen told me I had to download an update for the NAV unit, which I did, it took less than 30 seconds. Then, another 20 seconds for Installation, and then all was good to go and worked perfectly as always. All other presets were and are fine. It seems Lexus figured this out pretty quickly, kudos to them.

 

Email letter I got from Lexus yesterday. Has links to FAQs, not much. I might have got it from either getting it fixed by the dealer or the Lexus Drivers website were I have an account.

Dear Mr. Zorn:

You may or may not have recently experienced difficulties related to the navigation display in your Lexus. We apologize for any inconvenience.

Errant data broadcast by our traffic and weather data service provider was not handled as expected by the microcomputer in the vehicle navigation head unit (center display) of 2014-16 Model Year Lexus vehicles.

In some situations, this issue can cause the head unit to restart repeatedly, affecting operation of the navigation system, audio and climate control features, and the hands-free mobile phone functions. The data suspected to be the source of the error was corrected Tuesday, June 7, at 11:00 pm PST.

The correction is a forced reset and clearing of the errant data from the system.

Lexus owners experiencing these issues should visit their dealer for a complimentary system reset and a confirmation of the system. Until then, owners of affected vehicles should exercise additional caution when driving. We regret any inconvenience you may have experienced.

If you have further questions, please visit our FAQ site at http://lexus.us/1Xb4cMz or contact our Lexus Customer Satisfaction Department at 1-800-255-3987, Monday through Friday, 5:00 a.m. to 6:00 p.m., or Saturday, 7:00 a.m. to 4:00 p.m., Pacific Time.

Lexus Customer Satisfaction
