Incomplete Charging

[LucidAT-KC]

I have a Lucid Air Touring. Delivery date 4/2/2023. I have a 220 hook up in the garage. When I get home I plug the car in every night. I have the charge limit set at 80%. In the past, the next morning the car would always be charged to 80%. However, for the past several weeks, the next morning the charging has stopped well short of 80%. Often it has charged for only an hour or two and then stopped. Any idea why this is happening?

Here it has stopped charging at 195 miles for no reason. Well short of 80%

What’s the setup?
If the charging is done via a plug-receptacle set up, it could be a bad receptacle (substandard). Could be a loose connection.

Do you find the charger blinking red if you happens to catch it after it stopped charging? That error code (number of blinks) indicates the specific fault. As @EVCar mentioned, it most likely due to a low quality NEMA outlet and it is a fire hazard. Do you know if this a homedepot or Lowe’s NEMA? If so, try changing it to a Hubble or Bryant. A friend my mine in Texas had this same issue and changing the NEMA to Bryant fixed it for good.

I have a 220 that was installed in my garage initially for a Tesla I owned prior to getting my Lucid. It was put in by a Tesla certified electrician.

NEMA, Hubble, Bryant. I have no idea what you are talking about.

NEMA, Hubble, Bryant. I have no idea what you are talking about.

The outlet where the charger is plugged in. That is a NEMA 14-50 outlet.

Here is one that my fiend used to fix the issue. It is pretty easy for an electrician to switch out, if you don’t want to DIY.

Which receptacle would you recommend:

Either one is fine. Both are heavy-duty and are rated for charging EVs.

They talk about tightening all the connections with a torque wrench (which I do not have). How important is it to use a torque wrench?

It's very important to make sure that everything is tightened to manufacturers specifications. There is an enormous amount of current passing through there.

You can buy a torque wrench on Amazon for $35-50. They're commonly used by gunsmithing hobbyists. Torque the receptacle connections to spec, then form the wires so that you can shove the receptacle into the junction box. Then torque the connections again.

Please torque them to spec. That is extremely important. If you would rather hire an electrician, that is also fine.
