If you just drive it with the lights off you won't have a problem. You don't have to get it to do a tpms relearn.

I purchased my LED side markers from SOUTHERN CAR PARTS installed them back in April. No problems...no codes. Just returned from a 3000 mile road trip again zero problems.

Default Not sure I'll try again..

I like the look of these side makers, especially the added brightness, but I'm apprehensive on trying again not to mention that my wallet still hurts. I had a bad experience on my 2016 Camaro SS. I went thru three different sets in two years. Same M.O., within three months, LED elements start to fail, one by one. By the sixth month, at least one sidemarker from the set was totally burnt out. Three times this happen. Three times I replaced the entire set. Twice with Oracle products, I don't recall what brand for the third one. I was considering trying again on the C7 GS, but now that I see other forum users getting wierd error codes, I think I will pass. Not worth the aggravation.

I was an early adopter and put the ferrite chokes on mine which seemed to solve the problem for me, until 2 nights ago when I drove the car on the highway at night for several hours. The warning lamp came on as I was nearing home. Didn't seem to affect anything and if for some reason it does reduce performance I don't see that as a huge issue while driving at night anyway. I may yet replace mine with the Oracle brand but it will be over the quickly approaching Iowa Winter while the car is in storage.
I still prefer the looks of the JWM lamps with the thinner black edge than the Oracles. Those look closer to the appearance of the Z06 taillights but will wait for a bit to decide as I have home damage from the recent wind storm in Iowa that needs to be dealt with first.

Is there some sort of mod trickery folks are doing to get their Oracles to sit flush?
My fronts fit perfectly, but its the rears that wont fit. Back of the rear marker lights so thick it wont even snap in at all.

Well nuts. Went on a 200 mile drive last night and the TPMS threw a code from the passenger front tire. Now I shall have to do some research for the fix.

I put a set on my 2016 yesterday. They are IJDMtoy brand. Today I made a 50 mile trip and around dusk my driving lights came on and shortly after I noticed the tpms warning light come on. Having read about it here I was aware. Drove for several miles and about a half hour the idiot light shut off and the tpms for the front right tire started working again. I imagine I will have this happen again so...... does the ferrite core fix actually fix the problem?

Ammo - As an update to my earlier post, at least in my case, the chokes I installed did not solve the problem. Approximately 15-20 miles after my lights come on, I get a TPS error on the dash and when checking, it is always the RF sensor that is being interfered with. So far I have not attempted to see if any thing else will cure the problem. As has been reported in this thread, it appears that some owners do not experience any problems, others do.

The ferrite beads and/or faraday tape have NOT been confirmed fixes as far as I know. Some have attempted to use one or both. But no sure fire fix yet.

I also did both and went a step further and soldered a 10pf capacitor to the left rear side marker, no luck!

Geeeze, sounds like were just not going to get a fix for this. Unless we put the more expensive markers on like Elmer and a handful of other members did.

The TPMS in my 2016 operates on a 433 MHZ Frequency. Anyone know how to figure out what the frequency is being put out by the LED lights? Knowing these two things might give us an idea on how to block the LED frequency if that is what is causing our problem. Anyone?

@Ammo
et al
I am one of the folks that had luck with the ferrite chokes, until, the end of this cruising season at which time my 19 Z began to lose the right front wheel pressure display like many others. Do not know what has changed since earlier in the year, only that the issue appeared after most of a summer without seeing this happen. Like others if I drive for a while after the display disappears it comes back on again. Strange!
My car is in storage until roads are clear in the Spring due to living in snow country.
I had replaced the license plate lamps with LED bulbs which are located close to the TPMS receiver so will remove those and put conventional bulbs back in to see if that may help. With every other bulb being LED except for those and the trunk lamps this may be something to consider but possibly not if others haven't changed those lamps. The license plate lamps come on when the side markers are lit so...maybe. Perhaps this was encountered by GM during development and that is why they are incandescent bulbs.
Regarding the 433MHz frequency interference, it could be attenuated coming from the side markers by putting a 10 pico farad capacitor in series with a 36 ohm resistor and connecting them across the leads going to each of the side marker lamps. That was my original thought regarding dealing with this issue last Spring but when I had (temporary) success with the ferrite chokes at the time I dropped it.
