I have a loved one who has a 2018 Prius Prime Advanced. The dealership said that there was supposed to be a firmware update so that the sensors and auto-braking systems didn't go crazy while the car was in neutral in a car wash. Anyways, the person at the dealership said that in addition to the firmware update, there was an update for the map data that would cost $600. This is ridiculous. I mean, you pay $35K+ for a car and then they want you to pay $600+ for something a lot crappier than Google Maps, which is free? If the car's firmware gets updated at no cost to the owner, then why would the map data cost anything? Anyway, the person at the dealership apparently did not install the new firmware. If I bring up the firmware history on the head unit, there's nothing. If I look at the current firmware details, I see this : Software Update Model ID: 16TABDNA-AA01 SAM ID : BAAAAFOQHH Hard No.: 86100-47591 Navigation Current : R10A5530 Navigation new : - Anyways, the person at the dealership tried to take the car through a normal car wash but it auto-braked in neutral -- ie. either there was something wrong in the firmware update or no firmware update was ever installed. Has anyone else experienced these issues? Thanks, jdb2
$600 is wrong. I’ve heard as high as $200 though. Changes are minuscule between versions Recommendation is unless you live in an area under recent construction wait 3 or 4 years before updating or not at all.
I think you are talking about the "Special Service Campaign J0D" Read following thread. I don't have advanced trim, so I did not get the letter. J0D - Prius Special Service Campaign | PriusChat As far as Nav map update is concerned, just forget about it. Any phone app or stand alone GPS unit will do far better job than Toyota's (or for that matter most any car maker's) in car Nav system.
Actually I did. Once. It was in one of those car washes where you sit in the car and it pulls you through. If it was a traditional full service car wash I would not have know about the problem. My personal experience was the warning indicators and alarm sounds were disturbing. I don't know if the car ever applied the brakes which would be the big issue. I fixed my own car with Carista but it's going in Monday to get the official fix. Right now my car disables the proximity sensors whenever in neutral. I don't know what the Toyota fix does instead of this or in addition to this. I can envision the worst case scenario for this problem being the car applies the brakes and keeps them applied long enough so the car is no longer moving but the car behind it in the car wash keeps progressing and rear ends the Prius. Not a good thing for both cars. If you don't have a Carista or equivalent programmer you can make a note to always disable the proximity sensors using the MFD Settings before you go through the car wash until you have the Service Campaign applied at the dealership. I believe they are turned on again automatically after a restart of the car.
Well, I live in the greater Houston area, and the Prius nav system doesn't even display the names of minor streets in subdivisions close to where I live. When I went on a road trip the street info was better in the middle of nowhere in Texas in little burnt out hellhole towns But, we do have a lot of construction. jdb2
Thanks for the tip! I know that something like Google Maps is so much better, but the only complaint I have is that it's much easier to use on the big touchscreen display in the center console. I know that Comma.ai offers hardware and software to customize the head unit, but it costs upwards of $1K jdb2
Thanks for mentioning Carista I've heard of it before and I just looked it up and it provides the features that I'd need to fix some of the problems with the car's software, and, it costs *a lot* less than Comma.ai Well, apparently the "Toyota fix" wasn't a fix in my case. When the car's firmware had been purportedly upgraded, a person from the dealership took it through the kind of car wash that you describe and the car's warning systems went nuts. He wasn't wearing his seatbelt and said that he almost hit the windshield when the car auto-braked. The car was in neutral, so, apparently, the firmware "fix" wasn't a fix at all. Thanks for the info For now I've been using the suggestion from another member of this forums, whose name/handle I can't recall unfortunately. They said that before entering the car wash, turn the car off, then press the power button twice in rapid succession and then depress the brake pedal and hold the shift handle in the neutral position. This worked for me, but it's a real PITA because when the car reaches the end of the car wash one has to turn it off and on again while the track in the car wash is causing the vehicle to bounce because the car is in park. Also, be sure to turn off the auto-wipers and the auto-steering lane-keeping system. jdb2
I did google 'Toyota "SAM ID"' several times a while ago but I couldn't find anything that actually explained what the code meant. Maybe someone with more knowledge can chime in here? jdb2
Lane departure and steering is non functional below 32(?) mph so that won’t be an issue is a normal speed car wash.
I never had a problem with the brakes or anything when I go in the car wash. They're beginning it was hard to get it into neutral. But I put it in neutral and the car just rolls on the wheels from the auto wash.. I now go to car washes that is automatic, drive in, stop. And the automatic laser Car Wash does it thing. Doesn't hurt the tires or causing your car to gey missed aligned. And no scratchs. Posted via the PriusChat mobile app.
This is the dealer trying to put a big markup on the customer. Thanks, but no. You could likely call all the local dealers and get a much lower price. Or, just skip it. It's likely that the road in the other side of the country from you that changed a bit isn't one that you drive on.
The update in Special Service Campaign J0R is for the Clearance Warning ECU, not for the Navigation Receiver Assembly (radio head unit), so it’s not surprising that the latter wouldn’t have a record of it. As far as I know, the only way to tell if the J0R update has been done is to use a Toyota Techstream diagnostic system, or equivalent, to retrieve the version number (“Calibration ID,” in Toyota’s terms), shown in Techstream under Advanced Parking Guidance/ICS/Intuitive P/A. For the Prius Prime, the Technical Instructions for Special Service Campaign J0R document (available by subscription to techinfo.toyota.com) says the new Calibration ID is 8934F470307, which replaces 8934F470303 or 8934F470304.
They're trying to gouge you. The update should be $179. It comes on a micro-SD card and is user-installable, so no additional install charge. But really not worth it unless you're dead set against using your phone or a stand-alone GPS. My experience is Toyota's map updates are already a year (or more) out of date on the day of release.
As pointed out earlier, there are a bunch of independent computer systems on the Prime, each with its own firmware, so when one is talking about a "firmware update", one has to know which system is being discussed. The firmware version info shown on user displays is a very small subset. It used to be that all it took to work on cars was to be a competent mechanic with a standard set of wrenches and screwdrivers and such. Now one has to also be a computer tech with access to expensive computer diagnostic tools. And the Prime is at the high end of this computer sophistication.
I just got mine updated today at Frank Toyota (National City, Ca) for $140. (which is still pretty high IMHO. I am trying to find the change notices.
