For those of you that had the TSB done, did the dealer put a sticker (Authorized Modification Label) under the front of the hood next to other labels? They said they did the TSB on my 2016, but no sticker was affixed to the hood.

I don’t really understand the hesitation TSB. I get flashing the ECM, but I don’t get the battery reset procedure. If you disconnect the battery (and any other power source) from the electrical system wouldn’t you lose all settings? When they did the TSB on my car, all settings were maintained. If you put an alternate source of power on the system to maintain the settings, aren’t you defeating the purpose of a battery reset?

Not only did I not get the "completed" label, but they did not do the battery reset. I am going to take it back to the dealer and tell them to do it over again and to reset the battery leaving it disconnected for at least 1/2 hour. I'll post if the problem has been corrected.

also the 2018rx......i had a 2016 and that didn't have this....it drives me crazy.....i've been to dealer numerous times and the service mgr recognized the problem we tested the car for quite some time and he said they are hopefully working on a fix......he also said they probably won't because of mileage ratings....i also run in sport mode and that helps but the car still skips.....
