I'm seeing extremely irregular updates for the charge history for my 2024 Prime in the app. It was updating daily for the first month or so, but since about mid-December it will go upwards of a week without reporting anything, then backfill data incompletely. This morning my history shows the most-recent charge (morning of January 29th) then skips back eight days to January 21st. To be clear, I am having no difficulty charging the car, I'm only having trouble seeing the data via Connected Services. I'm still on the initial Connected Services term from the dealer, but if this is the quality of data it's going to give me, it is not worth the $. The data must be available in the car somewhere, but I haven't been able to figure out where. Any clues? If I can read the data directly from the car I will allow the Connected Services to expire when the term runs out.
I'm also interested in response from this forum about the many flaws of the Toyota app, more specifically the plug in vehicle aspect of the app. 1). Current state of charge is inaccurate. 2). Energy delivered shown in the charge history is inaccurate. 3). No info of charge rate through the app and in the vehicle. 4). Find a charger feature of the app is useless. Thankfully plugshare phone app is a great alternative when public charger is needed. 5). There is no find a charger option via the vehicles infotainment system. I did emaile Toyota about some of these issues around 5 days ago and no response. I would guess the above points are design issues and not actual software bugs, but regardless, simple features should be available for our vehicles which is already available for Toyota designer to see in the background.
I'm a software engineer by profession, and when it comes to "actual bugs" there are definitely a range of types. My company has a case we consider very bad, which is the "silent wrong answer", i.e. rather than presenting an error state, the software tells the customer something which is wrong. An example would be doing a units conversion (e.g. miles into km) and presenting an answer like "1 mile is 0.62 kilometers" without any error messaging. "Energy delivered shown in the charge history is inaccurate" is a silent wrong answer; that's a bug which requires a fix in my opinion. It's better to show no data at all than provide a silent wrong answer. (I do not have the tooling to verify this, myself.) My guess is that this isn't a bug with the app but a bug with the services collecting data from the car. Either way it calls for a fix. "Current state of charge is inaccurate" is what we would call a data issue; the app is showing what it knows from its online data sources, but those sources have inaccurate (or, at best, incomplete) data. I'm OK with best-effort data if I know it's just a best effort. But presenting inaccurate or incomplete data as though it's complete and correct is maddening.
Have you contacted your local dealer regarding your concern of charge history? I ask since Toyota Brand Engagement Center answered back to me and suggested I contact my local dealer. I will call my dealer this week to follow the process they are suggesting, but I have zero confidence dealer will help since they are not app developers.
After chatting with Toyota Brand Engagement team and my local dealer, I will be taking my vehicle in for service as suggested by my local dealer. I will report findings end of the week. I think it's an app issue, but let's see what happens.
I came to the same conclusion on my Gen4. Seems they haven't made any progress in fixing these bugs. If that information is really that important to you, some in-home chargers will report over Bluetooth and/or WiFi. Hope this helps....
