Not moving when Drive button is pressed

Not sure of an answer, but some more detail will help.

Is everything else normal?
No error messages, everything seems to be perfectly normal on the dashboard?
Does it move if you put it in reverse? Does the Drive button light up when you press it?
Anything going on before this/assume it used to work fine?
Did this happen while you were driving, or only once the car was turned on from off?

Parking brake engaged ? Easy to miss as the indicator is quite small on the dashboard.

On a related note - Parking brake will automatically engage if you are in "D" + "brake hold stopped" and unbuckle the driver seat belt.

It automatically turns off when you hit the pedal either in R or D, too...
 
What might be the possible causes of a Clarity not moving when the D button is depressed?
Based on some of your recent posts, I assume the vehicle you are referring to is the 2nd Clarity that you purchased at an auction (and it has a lot of rear end damage) ? If so, when a vehicle has been in a significant collision there are all kinds of things that could 'prevent it from moving'... The list is endless.

It is probably futile to try and solicit repair advise from a forum like this with such vague details and when the vehicle has significant damage.
 
Sorry for the delay. I didn't have the vehicle in my possession at the time but since it was minimal bumper damage, I guessed the issue wasn't related to the accident.
Turns out it was out of gas, no charge and a dead 12V.
After adding gas and a new 12V, everything engaged as normal. Had it on a slow charger today and its full.
Is there anyway to gauge or some kind of programmed protection so battery doesn't get discharged completely and cause potential long term damage?
Edit:
Found this thread which answers a lot.

There's probably no way you can know how long the battery in your used Clarity went without charging, so it could have suffered damage. However, when used regularly, the Clarity's Battery Management System (BMS) will prevent the battery from becoming discharged beyond what is safe for longevity. Some people never ever bother to plug in their Clarity; Honda's engineers anticipated that possibility when designing the BMS.

The wonderful @MrFixit has posted everything you need to know about checking your battery capacity here: https://github.com/clarity-phev/Battery-Capacity-Read
 
And if running the gas tank empty has caused issues (clogged injectors, fuel pump damage..anything else?), what might I check, listen for, etc.?

One caveat (especially applicable to your scenario) - it is very likely that your vehicle (since it was totally dead for a while) will experience a battery capacity 'reset'. This makes the capacity reading appear much better than it actually is. The reading will return to 'normal' but it can take many months and charge cycles to do that. It would be interesting to know what your capacity reading is since you have kind of a special case. Check out the instructions and let us know what your capacity is if you are so inclined.
 
Absolutely MrFixit! It would be interesting to follow capacity levels over time.

I purchased this for the first Clarity:
Vgate iCar Pro Bluetooth 4.0 (BLE) OBD2 Fault Code Reader OBDII Code Scanner Car Check Engine Light for iOS/Android https://a.co/d/6e597Pi

Is it comparable to the one you're instructions list which I think is the following:
WiFi ELM327 OBD2 Adapter Scanner Reader for Android iPhone iOS ELM 327 OBD2 Scanner WiFi Wireless ELM327 OEM WiFi Adapter OBD OBDii Reader ELM 327 Adapter Reader Scanner Diagnostic Tool for Cars https://a.co/d/1HUlaCh

Are you asking about the 12V battery or the traction battery?

In my experience, owning a Clarity for 4 1/2 years, during which time the 12V battery was discharged on two occasions, I learned that a healthy 12V battery will hold a charge for 4-6 weeks, but not for 6 months. We never activated Hondalink or installed a dash cam or other device that could potentially add a load to the battery. In addition to having a Lithium jump pack onboard, I’d recommend using a battery maintainer if the vehicle is not expected to be operated for more than 4-6 weeks.

My experience with Lithium batteries, 2 PHEV’s, an RV and boat with a trolling motor, is that they will hold a charge for 2 years or more. The Clarity was left with a “fully”charged battery for 6 months. The battery gauge on the dash indicated no discharge over that time period. Likewise, the lithium batteries in the RV have been left to sit for similar periods with little to no discharge occurring. I use a Victron battery monitor on the RV. Interestingly, the battery manufacturer, Lion Energy, recommends fully charging the battery, after which it can be stored for up to 2 years. Other guidance is to charge a lithium battery to 40-60% SOC prior to long term storage.

I was referring to the traction battery but good to know re. the 12V discharge time and jump pack/battery maintainer.

Possibly pointless, but just in case we are going to keep checking for any traction battery discharge (fewer bars) from the time we unplugged the charger (this am).
 
Yes, with a dead 12V battery the car will not move without a jump start or tow truck being involved. Those little details can help us help you.

I fully understand! It was all a massive surprise/headache to the car carrier driver, us and the tow truck driver. I asked the car carrier driver what the issue was and all he said was it just kept popping back to park. No mention of anything else. When I suggested a couple things he mentioned something about him having 40 years of experience. There was a bit of a language barrier. o_O
The auction listing said Runs and Drives and the auction picture showed gas and a charge but if course, no idea when the photos were taken and yes always a risk, sight unseen.
Sorry my first post was so vague.

Anyone have or know of published data showing battery degradation rates over time under normal use?
Re. the clean car extended battery warranty, if the car was sold in a state that offers the warranty, it's covered even if it isn't currently registered there when the warranty is claimed? And if it's a rebuilt title, it is also covered?

HV battery really isn't something you should worry about. The symptoms of it failing are obvious, and we haven't seen many failures of it.
