UMC Failure

[Shadious]

I have the original gen1 charger from my 2014 model S (40 amp version). The car has 89k miles on it and has also been charging our model 3 for about 20k miles. Yesterday after charging our model 3 to 100 (two days in a row for road trips), the charger stopped working. I got the 2 red flashes on the front of the charger, which, according to the manual is a faulty ground. I plugged our gen 2 UMC in and the car charged just fine. It leads me to believe the UMC gave out on me. Before I throw it away and buy a new one, does anyone have any suggestions on what might be wrong with it?

Update: thanks to another forum member’s suggestion, I tried cleaning the contacts on the charger and it worked. Just used a bit of rubbing alcohol on all the metal bits (see pics) and hit the reset button on the back. Good as new!

Also, these gen 1 chargers have a history of failing. If it does and you take it in to the SC they should replace it for free, although it may be for a gen 2.

Hmm, I did not know that... but, I like the Gen one so much better, I’d be sad to lose that extra charge rate

Mine failed a year and a half ago and they still had some gen 1's so I asked for that and got it.

Awesome, I’ll keep that in mind, for sure! Pretty good of them- I assume you were out of warranty...?

I'm Salvage so am excommunicated, but didn't trouble them with that information.

I called Tesla and they sent me a gen 2 when my gen 1 failed. I wish I would have known to clean the contacts to see if that helped.

If you’ve had the UMC for more than a year. Most likely the failure will be out of pocket. You might get a goodwill here or there but good luck with that.

I thought the UMC that came with the car had the 4 year warranty. No?

 

[swegman]

UMC (and HPWC if purchased at the same time the car is ordered (at least back years ago)) is covered for 4 years under the new car warranty. An HPWC and/or UMC purchased afterward only has a 1 year warranty.

At the time these were failing en masse and there was no question.

Can't speak for now though.

My gen 1 UMC dates back to 2013. Charges my P85 at 40 Amps.
