Hi, so like the title states. i was driving on the freeway yesterday and about 30 min every warning light and notification popped up. I know hybrids do weird things like that when the 12v battery gets low but I've never had it happen while driving. regardless, I replaced the battery but it happened again. only odd thing is that during the 1 hr drive back all the warnings and lights turned off for about 10 min then back on 2-3 min later. it did this twice and is currently on.
anyone ever have this happen? i checked a couple of the codes and it mentioned an error with the RF speed sensor being dirty. I removed it and all looks good.
anyone else ever have an issue like this?

I would get the battery checked out first. KISS.

have the NEW battery checked out?

Those symptoms are the classic symptoms of intermittent electrical connections IMHO. The going off then coming back on especially. So I would start at each of the battery’s terminals, checking they are indeed connected tightly, that the cables coming from the battery are not broken, that they are securely connected to the other ends. You’ll possibly have to meticulously check all through the harnesses. Common grounds are a good place to check as well. Then also look carefully for mice damage throughout the wiring harness…any signs of a rodent infestation?

no rodent damage at all, all connections look like new and don't look like they've ever been touched. car has 67k on it. it does seem like a wiring issue because of how intermittent it is but looking around i couldn't find anything. i'll get my hands on a newer version on TIS and see if their are any codes. mine is a little older version.

The sensors that throw those codes: what wiring connections, if any, do they share? I don’t have the wiring diagram for the RX but if you were willing to pay for, I think Alldata has them.

Also, what voltage are you reading with the new battery?

I don't know what the new voltage is but with the old battery the freeze frame shows it was at 13.8.

I overlooked that. In that case, I would look at the condition of the ground connections.

i see that you can get the service for 1 month but do you know if its available anywhere for purchase? i like having one for all of my vehicles.

Mostly are subscription based. You can also check out Prodemand (Mitchel on Demand).

I see you have access to tech stream. Go into vsc/trac live data and drive around. Watch the wheel speed. You can also pull up the exact code.

I had a similar issue to you in January. My car intermittently lit up like a Christmas tree. I wasted my money replacing the battery first and ignored the error code. It was a wheel speed sensor. It looked fine and worked fine on the highway. It triggered at low speeds though as it would drop out signal. I bought an off brand sensor from Amazon to try. I figured it was only $30 and it worked.

you can see it was my right rear wheel speed sensor in the freeze frame data below.

I could see nothing wrong with the wire. I’m in the rust belt so I did clean up the mounting location and scraped rust off the hub. It’s held in with one bolt.

The speed sensor set off the other codes (ignore the tpms codes- I was running winter wheels).

That is the beauty of data logging these days, especially with intermittent electrical faults.
