Battery Coolant Pump Issue - Take Two

[knewman]

Back in April my local service center called to tell me they'd received a pre-emptive failure alert for the battery cooling system in my Air. They replaced the coolant pump and had it back to me very quickly.

Fast forward to yesterday and I get the exact same call. The car is in for service now.

I know several others here have had the same pre-emptive pump failure notice, but has anyone else had it happen twice?

A few weeks ago, my Air was in service for weak AC performance. In addition to that issue, I reported that I occasionally heard a gurgling sound from underneath the vehicle. The diagnostic notes stated :

Technician found stored alerts for front and rear coolant pumps. Technician then began performing TSB-M0225-001-02 Coolant Pumps.
Identify and replace the affected MeWP100 coolant pumps. Perform post-repair verification to ensure proper system functionality.
Technician replaced power train pumps and performed coolant purge and thermal bring ups. Vehicle was test driven after to insure proper functions and no alerts or warnings are displayed. Vehicle working as designed.

From the invoice, there appears to be two pumps in the vehicle, one in the front and one in the rear. These are the part numbers of the pumps that were replaced were P11-M10105-00 and P11-M10106-00

Oh interesting, I'll have to compare the part numbers once I get the car back. Thanks for the info.

Lucid turned my car around in one day, my local service center rocks!

To follow up on this for anyone who is curious, the pump failure in April was for the battery coolant pump "BT" with part number P11-M10107-00. The pump failure detected most recently was a different pump "RDU" part number P11-M0105-00.

My service advisor explained that there are four total coolant pumps in the vehicle that have the same internal components - RDU, FDU, BT, and Cabin. In my case, all four pumps were replaced today as the current service bulletin advises any of these MeWP 100-type coolant pumps manufactured prior to a specific date should be replaced when an alert is triggered for any of them. My SA didn't say what that specific date was, but my invoice shows that the pumps they replaced were all manufactured between July-August of last year. The replacement pumps all had manufacturing dates in May of this year.

Waoh; I commend Lucid for this. Great Service and it's Proactive, Not reactive. Love to see this.

This issue happened with my car last Friday. I had picked up my car from service on 8/18 for minor vibration and seat leather issues.

Went on a roadtrip from Washington to Oregon and on 8/22, 30 mins after a DC charging session at EA, I started noticing loss of power when pressing the accelerator along with bumpy sensations. Started receiving the turtle icon with power limited message on the screen shortly. Few mins later, the car stopped accelerating at all. Had to pull over to the side and call customer service. They made me reboot the system and after that I briefly saw the Low Coolant...

Ugh that's terrible. Feels like these things always happen far from home too. Hope they get you turned around quickly.
