2024 Carnival sounds like a tornado siren

Hey. So, I actually know what’s wrong but wanted to share with the community in case any other Carnival owners ran/run into it.

Our 2024 Carnival LX has ~21k miles and the tires are getting pretty worn, down to about 4/32nds already. I attribute the premature wear to my wife’s heavy right foot since she drives like a bat out of hell and brakes hard. We’ll see what happens when we put some new shoes on next spring.

Anyway, we were coming back from a short (100mi) road trip and I noticed the van was HOWLING at like 55mph. It was very speed dependent, down to about 30mph and louder at higher speeds.

My initial suspicion was a wheel bearing since it was independent of the transmission speed and clearly tied to one of the rotating assemblies. However, after carefully listening for a while, I noticed the sound disappeared entirely over recently repaired patches of road with deep grooves.

So all that said, I’m 99.5% sure that the tires have reached a very specific point of wear that it chops the air against the road nearly the same as a traditional tornado siren. The sound then disappears entirely on sections of road with parallel groves because the tires can’t compress the air against the road.

2019 KIA Optima Lx, help im stuck

Hello everyone, sorry if this isn't the correct place to post this. I have a 2019 KIA Optima Lx with 119000 miles. Last Saturday when my wife and I were in the dairy Queen drive through, out car just died, no codes or anything, we were able start it back up but it would only run 10-15 seconds then die again. After a few times of this we were able to get it to a spot to have it towed to our house. We borrowed a scanner from AutoZone the next day and scanned it, no codes no lights on the dash. If we let it sit overnight it will start up and run but only about ten minutes idling and it will shut down, again no codes. So we asked around several people we know and they said crank and or camshaft position sensor, they don't always throw a code and are cheaper than a fuel pump. Those are now both replaced and still same issue. I swapped the starter and fuel pump relays and again still the same issue. So I'm just wondering if anyone here has any ideas before I go the fuel pump route. Any help is greatly appreciated, love this car otherwise.

Edit to add that restarting it cranked a bit before starting then dying and after it dies when you turn the key to the on position, you cannot hear the fuel pump prime. It feels obvious but I want to make sure there isn't something electrical that I need to check before replacing the pump

Auto-dimming mirror leaves 1/4 inch perimeter not dimmed

First of all, I was surprised and disappointed when I picked up my 2026 Sportage PHEV X-Line Prestige (top available trim) to find that it didn't have an auto-dimming mirror. In 2026?! Crazy.

I actually wanted the Homelink function more than the auto-dimming, so I ordered the part from CheapKiaParts.com and installed it today.

Part Number Part Name Price Quantity Total
DWF62-AU002 Auto-Dimming Mirror W/Homelink $263.78 1 $263.78

The auto-dimming function works correctly, but only dims the center/bulk of the interior of the mirror. It leaves about a quarter inch of UNdimmed mirror around the entire perimeter of the mirror glass surface.

Can someone who has the auto-dimming mirror please confirm that theirs works the same way? And does it bother you when driving at night to get headlight glare from the perimeter?

At least I can now open my garage door and fence gate with the mirror Homelink buttons rather than needing to carry around those FOBs.

[Warning to all Kia owners] Kia removed rear seatbelt pretensioners for Taiwan market. 5★ car became 2★ death trap. Is your country next?

  1. The Core Fact: KIA Lied in Advertising

KIA and their dealers marketed the Sportage in Taiwan using Euro NCAP 5-star results. The ads, the showroom posters, the sales pitch were all "5-star safety."

Taiwan NCAP tested the actual car sold in Taiwan in 2026. Result: 2 stars. The rear passenger neck injury score was 0.00 out of 8.00.

The reason: KIA Taiwan removed the rear seatbelt pretensioners and load limiters. These are standard on the 5-star Euro version. They cost-cut them out for our market.

  1. Why This Should Terrify You, Even If You Don't Live in Taiwan

If you own a Sportage in the US, EU, or Australia: Check your rear seat specs. KIA has proven they will remove critical safety hardware for different markets. You might have the same cost-cut version and not know it.

If you were considering buying a KIA: This is the company’s ethics. They will advertise global 5-star results while delivering a different, cheaper, less safe car to you. If they lie about safety, what else will they lie about?

If you think "this is just Taiwan": This is how it starts. Automakers test which markets will tolerate cost-cutting on safety. If Taiwan accepts it, your country is next.

  1. This Isn't About "Lemon Cars"

Forget the Lemon Law. That’s for cars that break down and can't be fixed. This car isn’t broken. It was delivered exactly as KIA intended: missing safety parts.

This is about "Major Defect" under Civil Code 354 and "False Advertising" under Consumer Protection Act 22. You were sold a 5-star car. You received a 2-star car. The law says you can void the contract and get a full refund, plus punitive damages up to 3x.

  1. What KIA Must Do Now

Stop using Euro NCAP 5-star ads immediately. That’s false advertising, period.

Offer a full buyback for all 2022-2024 Sportage owners in Taiwan. We paid for 5-star safety. We got 2-star.

Retrofit rear pretensioners and load limiters for free, or be banned from claiming any NCAP rating in marketing.

Bottom Line

You can criticize my formatting. I don't care. You already admitted you don't disagree with the premise.

The premise is: KIA advertised 5-star safety and delivered a 2-star car by removing rear pretensioners.

That is the only thing that matters. Everything else is noise.

So the question for KIA and anyone defending them is simple: 5-star ads, 2-star car. True or false?

update:

The difference between Ar4m and Aer4mp is important.

Based on Taiwanese automotive media reports, Aer4mp indicates a three-point seatbelt equipped with a pretensioner, while Ar4m indicates a three-point seatbelt without a pretensioner. The key letter is “p,” which stands for Pretensioner.

A pretensioner is not a cosmetic feature. It is a crash-safety device that tightens the belt against the occupant’s body during certain collisions, helping reduce slack and better control occupant movement. Kia’s own manual describes the retractor pretensioner as a system designed to make the shoulder belt fit tightly against the occupant’s upper body in certain crashes.

So the issue is simple:

Aer4mp = rear seatbelt with pretensioner
Ar4m = rear seatbelt without pretensioner

If the Taiwan-spec Sportage rear seatbelt is marked Ar4m, while other market versions or 5-star NCAP-related versions use Aer4mp, then this is a real safety-equipment difference, not just a wording issue.

Kia Sportage tire replacement

I have an AWD Kia Sportage and recently got a puncture on the shoulder area of one tire.
I went to a tire shop and they said the tire can’t be repaired because the puncture is on the shoulder. They also said because it’s AWD, I need to replace all 4 tires, not just the damaged one.
The remaining tread depth on my tires is about 7/32”.
Is replacing all 4 tires really necessary in this situation, or could I replace just the damaged tire, or replace two tires

I got T Boned…

My wife for t boned in my 22 Sorrento yesterday. Thank god the entire accident was caught on video from three angles by a Tesla driver behind her but I’m starting to get worried we could be looking at a possible total loss…

The back passenger wheel is angled inward under the fender. Probably about 30 degrees. She was so shaken up she didn’t get great view of what the suspension/axel looked like underneath but curious if anyone has any insight. We JUST bought my car, i literally made the second payment three days before the accident 😭 Obviously we’re in the midst of insurance and all the legal things but thankfully we know for certain we won’t be faulted since the other driver just plowed through a red light while my wife had a green arrow to turn. There’s minimal damage to the bumper and back door as far as I could tell.

Thinking of buying a Kia

Recently had to turn in my recalled lemon of a jeep grand Cherokee 4byE. Now I’m in a bind to get another car quickly. I’m looking for either a hybrid or all electric Kia as they are affordable. Other options are the Toyota RAV4. There’s so much chatter online where most are negative reviews. Is going to Kia’s a bad move?

Should I buy?

I’m a recent college grad and my current car (2001 jeep) just gave up the ghost this week. I’ve been looking at new cars over the weekend, and came across a Certified Pre-Owned 2023 Kia Sorento. I don’t have a big budget bc I just started my job, this car falls within a good price range w/ minimal mileage (about 35,000). BE HONEST… is this a good car? Please tell me all the pros and cons if you or someone you know owns this model/year.

Flat tire in 3 days

I bought a 2026 hybrid sportage sx prestige just 5 days ago. It had only been 3 days since driving it just from
Work to home and I had a flat tire for the first time in my life. I have never had a flat tire on my previous car and I drove it around for 3 years with zero issues. Is this just a coincidence? Finding it very hard to digest the fact that it’s just luck and not an issue on the tires of the Kia.
Anyone else having any problems with their new sportage? I got it replaced and since then my app has been giving me warnings of tire pressure too.

Hot take: the Kia souls ain't ugly. Not even a gen of them is ugly and ngl the worst is the new gen (still not ugly)

I ain't really a Kia soul enthusiast or do I love the car but can't understand the hate like it kinda looks cool sometimes. They're still mid cars but way to overhated

I’m going crazy… where is the brightness toggle?

On a k4 gt line turbo and this option is simply not here? Why? I only see brightness and default. No option to toggle auto what so ever. The constant dimming is so annoying while driving. Please tell me if there is a fix for this, moved somewhere else or if a screen reset or factory reset is nessary…

Carbon cleaning my Lambda 2 V6 almost cost me an engine

TL;DR: Did a manual carbon cleaning on my 105k-mile Kia Lambda II V6. Stripped two head bolts during reassembly due to Kia's notoriously soft aluminum blocks. Rescued it with an aftermarket thread insert kit. Installed an aftermarket oil catch can to help minimize future fouling.

**********************

At 105k miles, I took on a DIY carbon cleaning on my 2015 Kia Sedona SXL. GDI engines like the Lambda II V6 get notoriously filthy with carbon buildup on the valve stems, piston crowns, and fuel injector tips (my injector tips were pretty clean though).

Because these deposits harden to the point where spray-in products like Seafoam or CRC are entirely ineffective, I had to resort to manual scraping within extremely tight confines. It was such a miserable, tedious experience that it genuinely has me having second thoughts about ever buying another GDI vehicle. The only good news was that my 7,500-mile oil change frequency kept the bottom end completely free of oil sludge, but I'll be reducing it to every 5K miles going forward.

Unfortunately, the real nightmare started during reassembly: two of my cylinder head bolts completely stripped out.

At first, I blamed myself, but after digging into the forums, I found out these engines are plagued with incredibly soft aluminum blocks and shallow factory bolt holes. Several owners have reported head bolts backing out completely on their own over time, leading to blown head gaskets.

I talked to a Kia parts manager (who was a former service advisor), and his official diagnosis was that I needed a total engine swap. I refused to accept that. Instead, I tracked down a Huhn NS300L kit, which allowed me to carefully bore out larger holes in the block and install high-quality steel thread inserts. The fix is incredibly solid and should easily outlast the remaining life of the vehicle. If you end up dealing with this same headache, look into Kia's Warranty Extension Program (WTY039). I submitted a reimbursement claim for the thread kit and related parts about three weeks ago. Their autoresponder says it can take up to 60 days to hear back, so I'm just playing the waiting game now, but it's worth a shot if you're paying out of pocket to fix their soft block issues.

With the carbon cleared and the engine successfully reassembled, I installed an oil catch can to help minimize future fouling. However, I completely ignored the manufacturer's placement guide.

Most aftermarket instructions tell you to mount these highly conductive aluminum cans out in the open on a cold firewall or fender well. If you do this, the cold metal walls act as a passive condenser, dropping the hot blow-by gases below their dew point. However, this results in a canister that rapidly fills with a massive volume of milky, watery sludge that you have to constantly drain.

Instead, I custom-routed my lines deep into a hot dead-air pocket located right next to the engine block and the upper radiator hose. By using the engine's own radiant thermal energy to keep the aluminum canister walls very hot, water vapor from combustion is prevented from condensing. It stays in a gaseous state and passes cleanly out to be burned off as steam, so only heavy oil fractions get trapped.

I just pulled the canister for its first check at 140 miles, and the results are flawless: pure, dark, viscous oil with a heavy fuel smell, and no watery emulsion or yellow sludge at the bottom.

If I ever buy another GDI car, an oil catch can will be the first modification I install.

Interesting Fact from Salesman

Hi all - went on a test drive with a salesman who was basically a kid. We got to talking about how he goes to college part time and how he’s paying off some loans in this job. I asked how he likes this job and he said it was good but June was by far the slowest month since he started working. The dealership missed all its sales targets and the GM told the sales people they need to step it up. Two things: 1. I was shocked he told me this. I feel like he def wasn’t supposed to. And 2. Do you think we have more negotiating power than usual? I wonder what’s causing the slowdown. Is it dealership specific or all around the country? Thought I’d hear this sub’s thoughts.

RUN from KIA

Every brand has issues and every brand has failures, but not all of them blatantly deceive their customers the way Kia does; they dream up excuses to avoid diagnosing the real problem under warranty,which they know is costly,so take my advice and stay away from this brand. Sure, the design is nice, but the quality and after-sales support are the worst I’ve ever seen. See you in court.
