Here's the deal. The issue has been escalated to Jaguar Service National. Multiple parties are involved. I do not want to inject myself into the repair process and then be accused of being the problem. I will keep the forum updated on the process and the ultimate solution (hopefully.) If, after a reasonable amount of time there is no resolution by Jaguar, then the resolution becomes a buy back of an unsafe vehicle.

Maybe another thing to test here -
Bring the car to a stop with the engine running and gearbox in Drive. Press the button to shut down the engine. The engine will shut down and gear box should automatically shift into park.

Also, regarding the battery, did you dealer already check all the voltages and resistance of battery grounding?

Hope the issues will be figured out soon!

You and me both.

The car has been returned to me with a data logger installed. When it stalls while in my possession the logger will send the info to Jaguar (I believe in New Jersey) and will be analyzed. I was told other Jags are exhibiting the same behavior. It may sound odd coming from me in the midsts of this problem, but everyone at Momentum Jaguar Houston has been superb and JLR is also working to resolve this problem. Very pleased with the service thus far.

What year model do you have? (Sig block doesn’t appear on smartphone).

2020 F Type R Coupe

If other cars are exhibiting this problem, it is likely limited to the new models, as this is the first mention on this forum.

So I'll chime in. This *may* have happened to me in my 2020. I had a single instance in the first few hundred miles of owning the car where something futzed as I was nearing a stoplight and the engine cut.

I had cars behind me as well so I was moving fast to get it restarted and get out of the way. I think what happened is that I was feathering the brake pedal in just such a way to cause the eco-stop to kick in, but then somehow the system got confused as I let up on the brake pressure at the exact moment the engine shut off. I think basically it got confused on the eco restart process and didn't know what state it was in.

I was not rolling (that I remember), and was stationary for probably a half-second when this happened. In the subsequent 2500 miles I have not seen this reproduced but I am admittedly more attentive to turning off stop/start before I go anywhere.

I don't believe Eco Stop/Start is the culprit. When it dies, it is in drive, the engine is off, and the red battery icon is illuminated in the dash. Belief it is a faulty component or software related. Hopefully, the data logger will guide the engineers to the problem.

Car died a little over a week ago. Data logger registered the event and Jaguar Service National analyzed the event. The verdict is a software issue where the electrical system acts as if it is overloaded and shuts down. (I am not a technical person so please forgive the simplistic explanation provided by me.) At any rate Jaguar is working on a software fix. My understanding is that they have seen this with other 2020 Jags. I feel like a test pilot..............

Any update on this?

Jaguar National has determined it is a software issue and they have developed a software patch to resolve the issue. They are working through the regulatory hurdles for issuing a software update and it should be rolled out to the dealers in the next month or two. This is a problem that is related to the load the a/c system puts on the electrical system so it affects cars in the hottest climates during the hottest months.

Good to hear they are going to roll out the fix quickly. Thanks for the update.

that wasnt your flooded r that came in totalled then recently???? :)
