2021 Kia Seltos Transmission Problems Include Timing Chain Kinks, Sudden Engine Failure, and Overheating

Apr 1, 2022

The 2021 Kia Seltos has had a handful of first-year transmission issues. But with just one recall, no investigations, and 62 complaints on file with the National Highway Traffic Safety Administration, it’s been a remarkably smooth rollout.

Key Points

  • The 2021 Kia Seltos debuted in 2019 in Seoul, making its way to North America for 2021, making this model year the car’s official debut in the Western market.
  • A driver on the Kia subreddit has reported a timing chain kink resulting in long-term engine damage, thanks to metal shavings mixing into the oil.
  • Many of the car’s 13 powertrain complaints follow a chain of events from engine lights, to trouble shifting, to total transmission failure, demanding a replacement.
  • Overheating transmission may be an early sign of an oil leak, thanks to improperly heat-treated piston rings.
  • While it may be too early to call, the Seltos is shaping up to be a reliable SUV, with Kias averaging under $500 in annual maintenance costs, and major issues being relatively scarce.

2021 Kia Seltos’ Timing Chain Issues Can Result in Long-term Engine Damage

In this post on the Kia subreddit, a driver reports a fluttering noise in the engine starting at just 8,800 miles. And, when accelerating, they would hear a noise that sounds like “gears grinding.”

After getting it looked at, it turned out to be a timing chain that “went bad,” creating metal shavings that went into the oil, causing a ripple effect of damages throughout the engine.

The driver reports having had a pretty rough time trying to get the car diagnosed and the engine rebuilt or replaced, but eventually, they did get a new engine paid for by Kia.

While experiences like these aren’t common, they are more likely to happen with a brand-new model. There will always be some first-year kinks to iron out, and someone’s going to be the unlucky driver who discovers them.

Consumer Complaints Registered with the National Highway Traffic Safety Administration Report Sudden Transmission Failure

The 2021 Kia Seltos has one recall and 62 complaints on file with the National Highway Traffic Safety Administration, with only 13 of the complaints over powertrain issues.

Some of these powertrain complaints are pretty dire. One driver’s check engine light turned on after hitting 17,700 miles, and, after having the car towed to the dealership, he was told it required a whole new transmission.

The same thing happened to a few other drivers, usually reporting the same chain of events: light blinks on, car has trouble shifting, and then they need to replace the transmission, usually before reaching 20,000 miles.

The rate of incidence is so low that it is unlikely to result in an investigation or a recall. Luckily, with the 2021 models still under warranty, a recall may not even be necessary.

2021 Seltos’ Transmission Overheat Complaints May Point to Issues Related to an Engine Recall

Among the 13 powertrain complaints on file, you’ll find some reports of overheating transmission. In these cases, the issue may actually be pointing to a problem in the engine, being excessive oil consumption.

The car’s sole recall is for an oil leak resulting from improperly heat-treated piston oil rings. Without enough oil, your engine and transmission are more likely to overheat and suffer long-term damages. Fire hazard is a very real possibility here, as well.

The recall was issued for nearly 150,000 units, including both the Seltos and a number of 2020 and 2021 Souls. The recall was estimated to affect roughly one in a hundred Seltos owners, with these drivers getting brand new engines at Kia’s expense.

Again, this is simply an example of what can happen when you’re first in line. No car is going to be perfect on launch day. But, that’s what recalls and warranties are for.

A Few Kinks Aside, the 2021 Kia Seltos’ Rollout Has Been Pretty Smooth

Issues with the 2021 Kia Seltos’ transmission are relatively few but can be quite severe when they do occur. The 2021 Seltos is the very first model in the North American market, so you have to expect a few first-year glitches.

But with just one recall and no investigations, the Seltos’ debut has been remarkably smooth. There simply aren’t that many issues to discover in the Kia Seltos.

However, it’s not a bad idea to buy certified pre-owned. A CPO car will have been inspected by the dealership, and you can take comfort in knowing that someone else has already tested the car for a few thousand miles.

In any event, you don’t have much to worry about with a 2021 Kia Seltos. After a year on the road, the car has fewer than 100 complaints, no investigations, and just one recall. Those are pretty good numbers for a brand-new nameplate.

Frequently Asked Questions

By Stephanie Stephan | Apr 1, 2022

Does the Kia Seltos Have Automatic Gearbox Problems?

Kia issued a software update for Kia Seltos with 1.4L engines and seven-speed dual-clutch automatic transmissions. In those vehicles, the dual-clutch gearbox may skip gears and overheat in heavy traffic, however, overheating can be prevented by releasing the foot from the brake.

Does the Kia Seltos Have a CVT Transmission?

Base models of the Kia Seltos that include the LX, S, and EX, are paired with 2.0L four-cylinder engine and a CVT transmission. The Nightfall Edition and SX versions of the Kia Seltos are equipped with a 1.6L turbocharged engine and seven-speed dual-clutch automatic transmission.

Transmission fried
My daughter and I were going skiing close to Barrie Ontario. Just outside of Barrie Ont. The transmission went from drive to 1st gear on its own slowing down us considerably. We were passing a transport at the time driving around 120 km when it went into first gear. We manage to work our selves into the middle lane when the trans started working again. Right away we went into the slower lane because of what happen and then it happened again. A transport in the outside lane almost rear ended us but he managed to make it into the centre lane. We could not get off the highway onto the shoulder because of road work. We drove to the nearest exit which was around 5 km. We made it to aCanadian Tire parking lot and just sat for a couple minutes not saying a word. My daughter looked over at me and said, what would of happened if that was me driving? I wouldn't of known what to do. We almost created a major car accident. We managed to find a Kia dealer and drove in first gear through town to get there. Thats also when I found out that the road side assist we have sucks. So the car is in Barrie, we live in Kitchener and Kia will not reimburse us for the rental to get home.They will not supply us with car car while we wait to have it repaired. They don't even know if theres a transmission available for it in north america so this could take a while. Kia and Hyundia are off my list of cars to purchase ever again. My daughter saved up money for a few years to buy a newer car. What a shitty experience she is having with the car and with the support from Kia.

Transmission failure
We were driving home from my granddaughters' gymnastics meet on Saturday night at 11 pm in our 2021 Seltos. I had the cruise set at 70. All of a sudden, the speedometer started jumping from 70 to 69 and back to 70. I turned off the cruise and the car ran normal for a little while. Then it sounded like it went into neutral, and we started slowing down and couldn't go over 30 mph. We pulled off the road, which thankfully wasn't busy since it was 1 am, and parked along the road. Luckily my daughter was just ahead. We called her and had her come back and pick us up. We left the vehicle since we were only 45 minutes from home. Sunday afternoon we went back and was able to drive it at 30 mph to the Findlay, Ohio Kia dealer. When I started the car the check engine light came on. This was the first warning that anything was wrong. I was contacted today and told that the transmission failed, and they are waiting for Kia to approve a replacement. The vehicle only has 50,000 miles on it. I'm keeping my fingers crossed that all is covered under warranty. We had a Sportage that had almost 200,000 miles on it and never had any problems which is why we bought another Kia. I hope it wasn't a mistake.

Transmission/Clutch Actuator Failure
I love my Seltos, and I love Kia's. I think it's mostly my fault for buying a new model car in it's first year of sale. They're bound to have issues to kink out. Just over 30,000 miles and one year of ownership, I noticed my car was revving high, or taking longer to get to speed. I ended up taking it in and they would not let me take it home. My Clutch Actuator was failing and it was having transmission issues. I was an hour and twenty min from home, the rental places were closed, and they had no courtesy vehicles for me. Kia in Grand Junction was not cooperating and I had my friends child with me and no way to get home. After Crying on the floor for 2 hours not having a way home, they agreed to pay for a taxi ride for us. 3 days later, still no courtesy vehicle, they only agreed to pay a rental $30-$40 per day for 3 days. Leaving me with no way to get to work. Trying to trade it in now, as theres no estimated repair time for my car.. Reading these reviews it sounds like its going to be a long time. So that's great. Going to try to trade for a Telluride as they told me that they could "make it look good on paper" for me. So we'll see what happens.

Transmission Issues / Poor Service
My 2021 Kia Seltos 2.0T has been waiting for 20 days on approval from Kia to fix a transmission problem. I am unable to get a loaner vehicle from the dealer as all of their loaner vehicles are "out" and waiting for other repairs to be completed before being returned (probably NOT a good sign.) The service advisor said the code it was giving was that the Steering Gear 2 failure in transmission (the car would not shift into reverse) but waiting on Kia to approve this, along with other tests as we are within 1,000 miles of end of warranty on the vehicle and the dealer wants to make sure we cover our bases. Kia will not pay for a rental vehicle until they approve the repair, so we are stuck without a loaner or rental unless we pay out of pocket and take it up with our attorney to get reimbursement.

They force you to get oil changes at the dealer!
I bought a 2021 Seltos in April 2020. I had my first oil change (not at Kia) and within a few months there was a horrible ticking noise in the engine. The dealer told me that Kia does not alert buyers to this problem but the engines do not like aftermarket oil filters and they starve the engine of oil. The next phone call to me tried to say they weren’t covering it under warranty because of the company that did the oil change using the wrong filter (lies). After reading back notes and dates of conversations I had leading up to that suddenly they changed their tune and replaced the entire engine block under warranty but it was a good 3 months from start to finish.

Transmission Issues (don't recommend to anyone)
Regret buying a 2021 KIA Seltos. Barely drove the vehicle and its transmission broke down. Also, there are multiple warning signs popping up on the dashboard and the dealer doesn't know the fix. The dealer updated the software twice but didn't fix the issue. This is what they offered me "Kia will provide you with 3 Car payments reimbursed for a total of $1,252.53 as a gesture of goodwill for any inconveniences you have experienced and consider your claim fully settled." What good is it if I can't use the car that I am paying for?

CVT transmission replaced at 3200 miles.
I bought 2 Kia Seltos, one is a Sport and the other is the Sport turbo AWD, the ST AWD is awesome no issues, the Sport on the other hand is in the shop waiting for a transmission (CVT) blown in only 5 months and 3200 miles. We have been waiting now 41 days for the CVT to come in finally it is in LA and on its way so we should get it back within the next two weeks needless to say we are very disappointed in the Sport model, good thing I'm Leasing it I will be re-selecting when the lease is up.

2700 miles to a new transmission
New baby, new car, until it broke down halfway to the beach with less than 3000 miles on it and had to be towed in an area without a signal. Really nice to wait on the side of the road for an hour with my wife and 5-month old child for a tow truck. It was super hot and super dangerous. They are putting a new transmission in now but they said it could take a month. I can't wait for this transmission to nearly get us killed. Otherwise, we really liked the car! Do not buy this car.

Never will buy a Kia AGAIN!
At 1,000 miles I needed a new radiator as I was told during production they didn't "crimp" the seal around the radiator properly. Was told no engine damage was done given that it overheated and stalled while driving. No censors had gone off prior to the engine just stopping. Then two days ago engine was seized. No warning, no censors had gone off. I am now in communication with Kia Corporate stating I don't want my car back and I will never buy another Kia ever again!

Common Tranmission Issue
After 5 months of ownership, the transmission failed. I spent hours on the phone trying to get it towed and serviced. The dealership servicing it refused to give a rental or loaner. After hours on the phone with Kia customer service, they finally gave me a rental so I could get home from the dealership. 40 days later, still no ETA on the transmission. If you want to spend time at the dealership driving a shitty rental, get the seltos. Pain and anger guaranteed

Transmission failure
Transmission went out back in February right before the big ice storm in Texas. Roadside assistance couldn't get anyone out to me until the next day. Good thing I was close to home or I would have had to sleep in my car. The transmission was replaced back in March. Not even a month after I am having to take it back which I suspect is for more transmission problems. Don't recommend buying. First and last time I am owning a KIA product.

Check engine light
Currently at 700 miles haven't had this vehicle for a month. Was parked and the check engine light came on and turned off. Turned it on and was driving and it was jerking. This is my 1st brand new vehicle not supposed to have car problems yet.

Transmission Temp High is already two weeks in after buying all new Seltos. Going up the mountain with heavy traffic. Had to stop almost five times on side of the road to let it cool down.

Transmission went out twice in less than a year with under 10,000 miles. I guess every time you need an oil service, you will need a new trans also! Stay far away from this car.
