Drive System Fault Megathread

[hydbob]

Just out of curiosity, how to force the car to go deep sleep? Does exiting and locking it from key fob is sufficient to put in deep sleep or is there a time component too for which we need to wait for certain time period for deep sleep?

I was told 30 minutes previously.

For what it’s worth, you can see the status at all times with Home Assistant. You can watch it switch from Wink to Sleep so that you know when it is asleep.

Customer Care advised me that the car needs to be unoccupied (heavy items removed from seats if there are any), hazard lights off, locked, and bluetooth on your phone turned off (disables the mobile key during the power cycle). Once locked, stay at least 25 feet away from the car so it doesn't sense any keys and wait 10 minutes. We only ended up waiting 8 minutes and the car was able to power cycle and clear the faults.

Update on the automatic vehicle hold, brake system, and drive system fault that immobilzed the car for future reference for y'all if you ever run into the same issue:

The front and rear drive unit coolant pumps had internal faults and overheated. It did not appear that it was an original factory installation issue as nothing looked out of place and all wiring was done correctly with no leaks. Might have just been a faulty part. They replaced both and tested with no issues. Car's on a tow truck on the way back to me now and hope that's the last of it.

good info. I just got a call from Lucid service that my car was reporting a rear drive (RDU) coolant pump issue (failure to ramp up). they are going to come with a flatbed to pick it up (offered me a rental, they are out of loaners). Didn't get any notices in the car, but she said it hadn't failed just yet. How long did it take them to fix yours? Weird thing to me was they they need to do some diagnosis and told me it would be over a week to repair. can't tell whether they are short on resources or the problem is so complex that it takes that long to diagnose (and then order parts, etc.??).

They had the car for almost 2 weeks. The first week and a half it was mostly sitting while they were diagnosing and it took them about 2 days to replace the pumps and verify all was functioning properly. This was at the Irvine service location. Hope you get yours back sooner since they've already honed in on the pumps as the faulty part.

Thanks, great info. I was hoping it wasn't seals as that sounds more complex to fix. They said they'd send me updates each afternoon, I'll probably ask them given your info in hopes of getting it back sooner. Thanks for the info.

I took delivery of my Lucid Air Touring on December 16th. Aside from a squeaky steering wheel and the rear ventilation knob coming off (both of which were taken care of by the mobile tech), I hadn’t experienced any major issues — until a couple of weeks ago. That’s when I got a red warning message saying: “Drive system fault – contact customer service.” Lucid ended up towing the car on a flatbed to the Costa Mesa service center for further inspection.

It’s been about two weeks now, and I just received this update from my service advisor:

"At the moment, we are waiting for our engineering team to confirm whether the vehicle control unit will need to be replaced. We are proactively placing an order for the part in case they decide to move forward with the replacement."

My message was in amber instead of red, and it said “Drive System Warning, Contact Contact Custmore Care.” I drove back the half mile back to my house after the warning appeared, and my car ended up getting transported on a flatbed back to Lucid Service in Costa Mesa. Less than a fortnight later I got a brand new main battery out of it.

your service is probably completed, but fwiw i had this exact scenario. I got the call on Thurs, they hooked me up with a rental and said they'll come get it when they have the part in. They picked my car up on Tues around 7a and had it back to me the same day by 4p.

I had a Drive System Warning pop up on my GT a few weeks back. Car seems to run completely normal. BTW, this is not the Drive System Fault warning light that I have seen discussed on this thread.

I called Lucid and they asked me to take it in ASAP. The car has been at the Costa Mesa service center for about 2 weeks. No one knows whats going on yet. They said they were discussing with the engineers back at HQ.

Anyone else have an idea of what's going on or have had similar issues?

Lucky u were able to drive it. I’m stuck right now waiting for a tow truck. Won’t shift won’t drive. Just stuck in the middle of the road. Can’t even get it to neutral. Went through all the resets with CS too. Got this car in December 24.

sorry for your troubles
Any idea how many of these are I drivable?
Is this model year 2015 only?
