I get a similar thing from mine occasionally, but not when pulling away from a standstill. It happens every now and then when putting the power down at around 2000 rpm. There's a little jump or kick, like it's momentarily lost traction - but it hasn't because no TC light comes on. |

When was the gearbox fluid changed? But I suspect, it hasn't been done. Hyundai Ioniq 5 Ultimate. The family car.

I get these sudden jerks very occasionally, over the decade (paid cash for the new car). Seems to happen a few times then goes away for 6 months or so.

Im not surprised JLR main dealer cannot help. As far as they are concerned the FL2 is obsolete. Id try an independent LR garage for advice. Also changing the ATF is a good start. JLR says its "sealed for life" but that life can be quite short if you dont change the ATF (and other parts of the drive train). Jules |

Thanks for the responses: @nodge68, ATF fluids all done. Yes I started there last year and had all that done, it was quite expensive, and took way too long but it was worth knowing that this was completed.

The transmission ECM will automatically disengage the clutch pack when stationery to save fuel. It could be that you're feeling the clutch engage again as you release the brakes. Hyundai Ioniq 5 Ultimate. The family car.

We’ve had the same and again in summer months. Haven’t had it for about a year now. LR were not able to diagnose even after showing them how to repeat it. |
