Newbie here, wife getting her 2021 Kona (preferred) six months earlier than expected.

Today was the first 12 month routine maintenance on my wife's 2021 Kona EV.

Discussion items beyond the "normal" list of inspections due at this time:

Cabin air filter: the filter was pristine looking and my practice is to use a mini vacuum attachment (like a small drinking straw) and vacuum out each pleat and then re-install the unit for another year service. The R&R procedure is very easy compared to my TM3.

Brake inspection: the car sees service in severe winter conditions, therefor I remove all the brake pads and re-lubricate all the points on the pad backing plates and calipers that require brake caliper lubrication.

The rear brake caliper dis-assembly (with the e-brake module) was a non-issue as the caliper body was removed in the same manner as was employed for the front brakes; of course one has to be careful with the rear caliper body not stressing the flexible rubber brake line OR the wire loom for the e-brake module.



One "gottcha" to speak of when removing the rear brake pads from the caliper carrier:



None of the online videos (or the linked shop instructions below) mention that if one wants to temporarily remove the current rear brake pads, the "pad retainers" one way locking barb (all four brakes have these, but the fronts were not an issue) will make the job impossible unless one pulls the bottom of the pad such that the barb is "bent backwards"...just be sure to straighten the barb with needle nose pliers prior to re-lubricating and re-installing the lower pad retainer.

Strange thing happened yesterday:

I set the car up to only charge between 1900 - 0700 (to avoid peak charges) when we took delivery 15 months ago.

For the past 15 months, with no drama, the car could be connected to any (home a.c.) charger and it wouldn’t start to charge until 1900 (or if we pressed the orange button at the charge port to override the specified charge window).

Yesterday, I plugged the car in around 1230 and it immediately began to charge!

After forcing it to stop charging, I had to wade into the charge settings and noted that my 1900 - 0700 charge time specification had disappeared.

They have now been reset.

Has this happened to anyone else, where the charge time settings somehow get erased?

Thanks. Cheers.

 

Thanks. I’ll check the linked thread.

FWIW, there is no blue link account on this vehicle.

 

Based on an abundance of caution, I am going to perform some non scheduled "preventative" maintenance on my wife's Kona EV.

Her car has 8,700 km and has been in service for 15 months and three weeks.

Background:

The owners manual, when discussing the reduction gear fluid, only mentions "inspecting" at 30 month intervals, with a recommendation to remove and replace the fluid at 120,000 km.

I plan to swap out the reduction gear fluid within the next two weeks, pending acquisition of two liters of the specified 70W GL-4 reduction gear fluid and a replacement drain plug that is magnetic (Hyundai magnetic drain plug part number 00810 17121).

These following links will provide context:

I'll only post any unusual/unique observations here once the job is done; otherwise one can learn all about the details by referring to the two links above.

Many thanks to the explorers leading the way, including (but not limited to) @KiwiME and @OzKona

 

Update to the above: I plan to do this small project today.

The planned Hyundai magnetic drain plugs turned out to not be magnetic, so I will be using rare earth magnets placed on the outside of the current drain/fill plugs.

In this shot, this is the closest one of the magnets can be placed next to the remaining stack due to the repulsive force between like poles:

 

A strange thing happened yesterday when the car started to charge immediately, instead of waiting for the (set) times to charge (1900 - 0700), when my wife plugged her car into her son’s 32 amp home setup at 1530.

After a 20 minute (remote telephone session) walk through of what should have been a normal setting on her dash (for charging times, as have routinely been used for the past 18 months), we ascertained that, for whatever reason, all the times and settings to only allow charging between 1900 & 0700 were “off” and zeroed out.

Since the charging settings do not present themselves on the user interface whenever the charge port door is opened, I’m faced with telling my wife that she has to double check the timer settings prior to turning her vehicle off.

Any thoughts? Thanks.

 

Hopefully a one off event.

At least my wife now knows where those settings are and what their significance is.

 

Back in Aug 2020, right after my wife took delivery of her Kona EV, I set things up for her so that she could just get into the car and drive it without any pre-drive drama sessions.

Note: Since day one, she uses the “normal” instrument cluster (not “sport” or “eco”).

One of the items I set up for her was manual setting brake regen at level “3” (the icon is blue with the three arrow icons).

Anyhow, about three weeks ago, she complained that she had little brake regen.

I checked things out, and the car was set to manual setting brake regen level “1”.

I showed her how to use the paddle to increase the setting back to “3”.

On her next drive cycle, she complained again that the brake regen was reduced and, sure enough, the car was back into brake regen setting “1”.

Every time she goes for a drive now, she has to play with the paddle to force the brake regen level to go from”1” to “3”.

In other words, what used to be a “saved” setting (brake regen level 3) is no longer saved and every time she goes to drive her car, there is now this extra step to set the brake regen back to “3”.

I’ve been re-reading the manual numerous times, but I don’t know what we are doing wrong.

Why is the brake regen setting always defaulting back to “1” when the car is restarted? It never did this until about three weeks ago.

To confirm: she doesn’t like and/or want to use the “auto” brake regen setting (white icon until it locks onto a radar target) she prefers the manual (blue icon at all times) setting at “3”.

Thanks.

 

Cheers.

The car has not been to the dealer since sometime in early 2021, so the software hasn’t been touched.

I guess we’ll just grin and bear it until/unless we stumble upon some action that gives us back level 3 as the default.

 

Next time my wife uses the car, she will try these suggestions. Thanks.

Edit: I’ll post the results.
