Well its an AGM battery, not a lead acid battery, battery would be fine as long as the alternator is working.

It is a lead acid battery. The sulfuric acid is absorbed in a mat.

As for my comment on the other page, here is a picture of the DCT vent. Its nearly flush at the top of the transmission:

I'll eventually find a way to fix this barely protected section.

@1fastKona, been away from the forum for a few days and bebop beat me to the reply. This is why in my opinion lithium/lipo batteries are superior. I run one in my motorcycle and not only can it withstand full discharge cycles with little ill effects, you can let it sit on a shelf for a year and it barely loses any of its innate charge. Also the overall weight savings is pretty significant for competition/track purposes.

Just got my kona back after almost a full month later. Took 3 weeks to get the new transmission. car works great so far, just hope it last. Also they gave me some Hyundai gas additive to help clean my injectors. Said add it every 3000 miles to clean the carbon buildup from the cylinders or my engine would have issues @ 30,000 miles it would need to be de carboned.

don’t believe the gas additives “magical” powers when it comes to GDI carbon cleanup..
You really don’t need any additives if you use a quality gas. The gas doesn’t hit the part of the valves that can be affected in a GDI engine.. Just drive it and avoid short runs, drive it hard every now and then to help burn off contamination..

 

[leftydog1961]

Absolutely! Use top tier fuel. Forget the additives. Waste of money. When I hit 50k I did a CRC intake valve cleaner in TBI.
not sure if it did anything or not.

10k update on my transmission replacement and still no issues. I have to remind myself that I ever had any. Continues to be a great little car. ?

Seems to be a bad batch, haven't heard any new case in few months.

All it takes is one lazy or non caring employee pumping out transmissions day after day to ruin a good track record.

Sorry to jump in here. I just bought a 2019 unlimited in a year end deal and come across these DCT threads. Any way to know by VIN sequence number if you tend to be in the bad batch area? Anyone had the replacement also fail?

 

[Mainia1]

Nope, only Hyundai corporate knows, and ZERO dealers would now. You will know in do time.

My Toyota was still strong at 300,000km with just brakes and oil and I lost it as a trade in for my Konra. Now in the Kona I am on a my new transmission at 7k in after having to lose my **** at the dealer and had the mechanic tell everyone in the waiting area that I have a bad temper and I don't know how to drive. Upon replacement at another dealer the shifting WAS much smoother and now after a few months, mostly parked (battery dies after 2 days) it has started aggressively downshifting into 3rd at speed. Since I have been back to the dealer 3 times and they cannot replicate the issue. They are saying to wait for a class action lawsuit to get a 2nd transmission replacement. The front sensor doesn't work, the trunk doesn't close properly, the front brake pad separated into two and I needed to have the pad and rotor and later control arm and balljoint replaced. My key fob stopped working and had to be replaced, and my windshield cracked leaving my driveway. This is frustrating as I bought this partly because of good reviews and quality awards. I re cently rented a VW jetta awd for a trip and the combination of ergonamics and features you find and even the wipers and lack of fogging up I am ready to move on.

 

[Mainia1]

By your join date, can I assume you have a 2018? Why the control arm and ball joint replacement.?

 

[whitenite]

the trunk doesn't close properly

Can't help with yr other issues but this one, I complained to Service technician at the Dealer's on 1st (Free) service, that I had to slam hard every time in order to close properly. Guy called me over to the rear, unlatched & lifted the hatch-lid, told his assistant to open a door, any door, and leave slightly ajar. He then proceeded to drop the lid without force. It shut tight. Verdict: New car, good seals thruout ergo, airtight. Still works today on my Nov '17 Kona (1.6T DCT).

 

[Mainia1]

MY trunk did not shut right for about 2 months when new.I adjusted the rubber adjusters and it still was flaky for a bit. After 3 months I had zero issues. It just needs some seal crush time.

I have had my 2019 Kona Ultimate AWD for 4 months and put roughly 5500 miles on it. After a tow to the dealership prompted by a terrible burning smell, whines and clunking in 3rd, 6th and 7th gear, and a loss of acceleration, the technician confirmed my suspicion today and said the transmission needs to be replaced. I was given a 1 week estimated repair time, but I am skeptical of that estimate. The vehicle didn’t throw any codes or services messages, but it was obvious there was something seriously wrong. What started as a high pitched whine in those gears escalated to almost complete failure within less than 100 miles.

Even though the replacement will be covered under warranty, I’m concerned about the longevity of the vehicle and the quality of a dual clutch transmission...even if it is new. I bought this car with the intension of having it for the next several years and being able to put +150K miles on it without serious issues. Hard to say what the future holds with it being a newer model. This form has been insightful. Does anyone have any knowledge about how the 2018 Kona models with a DCT are holding up or a higher mileage 2019?

 

[whitenite]

Sorry to hear about yr gearbox ordeal. I hv a Nov 2017 Kona Elite 1.6T DCT (AWD), 50k+ km on the clock, still running fine.
I do tend to put it in 1st when moving from stationary, in order to avoid the "clutch slip" scenario (revving with not much acceleration), and change to D once I hit 2k or so rpm.

[SassyPepper]

my 2019 Kona Ultimate was having transmission issues at around 10,000 miles - service says the whole transmission needs to be replaced and it will take three weeks!
Has anyone had the transmission replaced and is the problem fixed.

 

[Scott13]

My 2019 Kona is getting a new transmission this week for similar problems. Hope it resolves the issue like yours.
If you are not sure, I would take it in and have service check it. Mine acted up for quite a while before I got a notice from Bluelink. Stalling on start is a classic symptom when trying to start a manual transmission in 2nd gear. It always performed better in sport mode, but I think that was just compensating for the failed gear.

I feel like I have a new car and am not sure now why I didn't get it checked sooner. The car I traded for the Kona had some serious issues and that dealer's service department made me feel like an idiot for complaining about it. I know that I didn't want to go down that road again; however, Hyundai handled it wonderfully. They gave me a 2019 Tucson to drive while they got a new part from Korea. They said there was not a transmission anywhere in the US. I cannot say enough positive about the experience, in spite of the fact that I had to take a new car back for a major repair.

Thanks for sharing your experience! I left my 2019 Kona at the dealership yesterday to have work done on my transmission. I brought it in for scheduled maintenance and a nail in a tire, but when asked how I was liking it I mentioned some annoying issues in first and second gear and it snowballed from there. The service rep’s eyes got huge when he found a report of what could be going on and he said they have to completely take apart my transmission. After only a few months of ownership I noticed it felt and sounded “clunky” (for lack of a better word) when it would accelerate slowly as I took my foot off the brake, and it seemed to almost stall going from first to second gear. I’ve also experienced a few scary moments of hitting the gas only to rev my engine without acceleration. It was all very reminiscent of being a 16 year old learning to drive a stick shift before I figured out the ideal gear speeds and how to work the clutch for a smooth ride. After reading that yours wasn’t going into 5th gear I’m now wondering if mine is having a similar issue; I’ve often felt like my RPMs were running too high at highway speeds. I’ve mentioned all of the above to other people riding in my car and no one else noticed a problem so I assumed it was user error or that maybe the quality of Hyundai was decreasing. This is my 4th Hyundai and I drove my 2006 Tucson for 10 years without issue so I’m relieved to know that Hyundai will do what’s necessary to make it right. Next time I’m trusting my gut and taking it in sooner!
