Hi,

My wife's 2023 F-Pace will exhibit the fast blinking turn signal about once a day. It is not regular and I cannot reproduce it happening. But if it happens when I'm signalling a turn, it usually will go away by the next time it happens.

It usually happens when I signal right. I've checked the turn lights on the outside of the car when this occurs -- it appears that the rear lights are not turning on when this happens. For example, when I'm signalling right and it fast blinks, both the rear right turn light on the truck and the rear right turn light on the fender do not work. When the problem goes away, both lights work.

I've brought it to the dealer and not surprisingly they cannot reproduce it and it's not throwing codes. I'm guessing this is an electrical connection issue.

This has happened since day 1. We bought the car new, but it had been sitting at the dealer lot for about a year.

Any thoughts?

 

I'm trying to figure out how to edit my post but can't find that option.

I meant to say "But if it happens when I'm signalling a turn, it usually will go away by the next time I signal a turn."

 

It's still under warranty assuming the odo is below 60K miles. When the problem occurs, take a video and show it to the dealer. Good luck

 

Yes, it's still under warranty. Thanks for the suggestion; was hoping there might be an at home fix.

 

My gut feeling is a loose connection or the right front headlight or right back lens assembly might be failing and needs replacing. Whatever the findings parts and labor will free of charge. It will take less than a day depending how good their electric technicians are.

 

I had this issue on my XE, it turned out to be the back turn signal bulb, once replaced it was all good.

 

A fast acting blinker usuall meens that a bulb is not working properly . Check bulbs & wiring

 

Most likely a ground connector

 

I had this issue on my 2023 F Pace too. As you say, the fast indicator click tells you that it's happening and in my case the entire rear cluster (both pieces) was out when that happened. No tail light, no brake light, no indicator. Nothing.

It's a serious safety issue - imagine driving at night on a highway, indicate and move and the person behind doesn't know you're moving and may not have even seen you properly

Hopefully yours is an easy fix. Apparently they have seen a few of these on Jag and LR due to a bent / loose pin on the wiring harness. Have them escalate to tech support.

Mine was never traceable. It must have gone in 10 times and replaced the light clusters at the back, the wiring harness, the body control module and I don't know what else. Eventually Jaguar took it back as I was not comfortable driving a brand new car with such an issue

 

I had this issue with my 23 F Pace SVR 88 edition. Dropped it off at the dealer, they were able to reproduce it and, after contact with Jagaur engineering, they replaced both rear tail light assemblies. Seems to be a somewhat common problem as I have heard of serveral instances where this has happened. It hasn't acted up since the repair. Good luck

 

Issue is, current production taillights have a defect that causes a false 'bulb out' reading which causes the fast flash and stores a code. Affects MY23+ with the LED tails it seems. The temporary fix is a CCF change to run them as DRLs until new parts are available. The fault will stop on the next cycle, so just turning the turn signal off and on usually solves it, which means most people don't bother with it too much, but yes it's an issue they are working on with the supplier for the lights.

 

What does a "false bulb out" reading mean?

The issue is less about the fast flashing. It's that the entire taillight on that side of the car is dead. So the indicator, the taillights at night and the brake lights are not functional. That's super dangerous on the highway - you indicate to change lanes to the left and not only is there no indicator but there is also no light at all on that side at the rear of the car.

 

The computer is detecting the bulb out and showing a fast flashing on the cluster to alert the driver. The issue is within the taillights, but the replacement parts are the same so the temporary corrective action is a software change to stop that. It does not happen when the taillights are on, so it will not be an issue at night. It clears on the next application, so if you get a fast flash, turn the signal off and back on, it will go back to working. Until the updated parts are out, the dealership can flash the car with an updated calibration to prevent that from happening, but it would require a visit to the shop unfortunately.

 

Ok - must be a different issue. In my case it did it intermittently irrespective of whether taillights were on or not. And it wasn't just a detection issue - the fast flash was because the taillight bulb was not lighting and the whole cluster went dead. No indicator, no brake light, no taillight. Just totally dark. It would come back on after a bit
Dealer Replaced taillight, wiring harness and BCM and various other attempts but unable to fix it. That's why I wondered if there were other cars seeing the same issue.

 

The lamps are the issue, the new ones are the same as the old ones so it doesn't fix it. The updated lamps are coming. In the interim your retailer can update the CCF to stop it.
