Had a crazy busy week so haven’t had the time. Going to at least get an email sent this weekend to start the process. 
You should definitely pursue with them. I received a replacement and I am up an running. Your trainer needs to be replaced.
Go online via the chat. Devon was very helpful. I purchased mine in Sept 2020 as well
Yup, I have a ticket opened and have since provided all the required info, including the original receipt showing it was purchased 9/23/2020. Eileen, in your case, did they email you a postage paid shipping label for you to send your defective unit back first? Just trying to get an idea as to when I’ll be back up and running. Last successful day on the Kickr was 11/29/23! 
Thank you
Yes once I sent info they sent me the label, I got to FedEx that day and sent back my old one. Once they confirmed the old one was with FedEx, they ordered the new one. All in it was 5-7 days, not bad.
I will! Thank you. So glad I found this thread, gives me hope I won’t have to replace it out of pocket 
Same story as many of you: last run the 10th of December, then off to winter break. Starting up this morning, connects just fine (after restarting my macbook), but Zwift doesn’t read any output of the trainer (cadence and power).
Open the Wahoo fitness app to see if the problem was on Zwift, but it too doesn’t pick up anything, although connecting just fine.
I have a fairly new Wahoo Kickr, purchased Aug 2023.
Add me to the list of frustrating Wahoo customers. Tried everything, even installing/closing every Garmin unit in the shed. Got the Wahoo Kickr 5 (purchased in Jan 2021) back to life this morning with data (power and cadence) sent through. Just to see it dead again this afternoon. Submitted a ticket with Wahoo CS.
I am so glad I found this thread
Trainer : Wahoo Kickr v5 (2020)
Purchased: 21 Dec 2020
Distance : 8539km
I thought I was going mad. Yesterday I had exactly the issues discussed, but after 40min and a missed start on Zwift I seemed to get it working.
But today all attempts have failed to get this working.
But having seen that some people are successful getting replacements shipped from wahoo I am hopeful of a Wahoo fix to this situation.
Yes, I have a Wahoo KICKR direct connect device.
I have the same issue being discussed in the thread and the Direct Connect makes no difference to the issue.
wahoo support told me it wouldn’t make a difference and the unit needed to be replacement.
I can confirm it made no difference.
@eileen_crowley have you success fully received a replacement from Wahoo?
I am based in the UK so wondering if Wahoo support/replacement process is different
I submitted support request over the weekend
Hi Andrew yes I did receive replacement. I live in US, not sure about international. Did you buy directly from wahoo? If so they should support(just my opinion)
could be different for the UK
Looks like they are going to replace mine too. 
. Just received my shipping label for the old one. Thanks for all your help!
Sadly i’ve got a 2nd hand one (v4 2018), i’ve had it for 4 years with no issues, and i haven’t been able to find a fix. Anyone with some luck regarding 2nd hand??
Guess i’m going to have to start riding outside… (or buy a new trainer)
FYI: No power/speed seems to be an ESD issue, which i found in DC Rainmaker’s post “Wahoo CEO Details Fixes for Issues Surrounding KICKR 2018 & KICKR CORE” back in 2019!!
I am on the same boat here. I was planning on a workout tonight and came to realize that the training was connecting but not showing any power. I did some test, then turn to the PC to see if anyone out there had similar issue. It looks like there is a lot of us with the same problem.
@James_Donald_SISU_Ra Interesting. Good Find.
ESD is certainly an issue with electronics, and I can understand that and it could be a user created issue, IF they were dismantling the device and accessing the PCB that controls it.
I read most of the article and watched the YouTube interview with the Wahoo CEO, and with the Wahoo explanation of the root cause. I see this as a design problem, they see it as an issue with the product, and really it is an issue Wahoo should resolve, by providing repairs/replacements
Now that was the 2018 model, I have a 2020. They should have fixed this problem, but the CEO did hint that it is a problem that is difficult to fix
Add me to the list, my one is just a year old (V5)… I have DirCon and that, BLE or ANT+ makes no odds… here we go then with Wahoo (again…had a SNAP that was a wrong un from the get go). I picked up a Jet Black Volt (aka HUB) for £209 from Sports Direct in June, to keep it as a “backup” in case the KICKR died on me in the depths of the Scottish winter when needed most… missus said I was daft… I updated all the firmware on the JB recently, looks like I’m going to be actually needing it now ffs… Think I’m done with Wahoo now (as a disgruntled RGT orphan lol)
In my case, rather than send my unit back, Wahoo Customer Service asked me to cut the power cord as close to where it meets the body of the Kickr and take a picture of the cut power cord with the SN in the same pic. Certified Refurbished unit incoming, with Monday ETA. Amen
