Kia Optima problems

kia logo

The Kia K5, formerly known as the Kia Optima (Korean: 기아 옵티마), is a mid-size car manufactured by Kia since 2000 and marketed globally through various nameplates. First generation cars were mostly marketed as the Optima, although the Kia Magentis name was used in Europe and Canada when sales began there in 2002. For the second-generation models, Kia used the Kia Lotze and Kia K5 name for the South Korean market, and the Magentis name globally, except in the United States, Canada, Malaysia and the Middle East, where the Optima name was retained until the 2021 model year. The K5 name is used for all markets since the introduction of the fifth generation in 2019.

First generation (MS; 2000)

From 2000–2005, Optimas were a rebadged variant of the Hyundai Sonata, differing from the Sonata only in minor exterior styling details and equipment content. It was first shown in South Korea in July 2000 and was the first product of the Kia-Hyundai platform integration plan.

In Australia, the Optima was introduced in May 2001, offered only with a 2.5 L V6 engine, and choice of manual or automatic transmission. The updated Optima was offered with a new 2.7 L engine, 4-speed automatic (the manual was dropped), and features such as full leather interior and alloy wheels were made standard. Thanks in part to better marketing, sales increased to 41,289 units in 2005, an all-time high. The Optima was sold until 2006, when it was replaced by the Magentis.

Common Kia Optima problems

The Kia Optima has been reported to have several common problems, with the worst category being engine problems.

Another common problem reported by Kia Optima owners is faulty starter issues. Many owners have reported that their engines suddenly wouldn't start at all, with no signs of what the issue is or that there was an issue in the first place. Although diagnostic tests don't show a clear cause of the engine problems, several owners were able to resolve the issue by simply replacing the battery and/or parking sensor.

The Kia Optima is also known for its faulty door latch problem, where it becomes very difficult to open the vehicle doors from both the inside and outside of the car. The cause of this issue is a faulty door latch assembly, and simply replacing the worn latch will often be all it takes to address the problem.

The main symptoms of a faulty throttle position switch (TPS) are the check engine light illuminating, combined with misfiring and power loss. According to owner reports, this issue tends to happen just after crossing the 100,000 miles milestone.

The Kia Optima’s weak alternator issue is also high on the list of reported Kia Optima problems. This issue generally comes to light when the car has been operating with high electrical loads, such as the driver running the lights, AC, etc., all at the same time – which results in insufficient battery charging capability, as well as making it difficult to start your vehicle. Some owners have reported that jump-starting their batteries or replacing the batteries helps solve the issue. However, several owners ended up experiencing the same issue over time.

In addition to these issues, there are also reports of door lock failures and transmission issues (software correctable) in various model years of the Kia Optima.

What year was bad for Kia Optima?

Kia Optima Years to Avoid: 2011

There were enough issues and pressure from consumers with widespread criticism that a class-action lawsuit was filed against Kia. Eventually, the carmaker recalled the 2011-2014 Optimas with 2.0-liter and 2.4-liter four-cylinder engines, among other cars.

Why are Kia Optimas so cheap?

The materials used are lower in quality than other manufacturers, but Kia is quite smart when it comes to production. Some of the cheaper plastics are used sparingly, so many of Kia's interiors look and feel fancy – but they still managed to save on production costs and pass the savings to the customers.

It was only recently that I discovered the recall information online, which has heightened my concern regarding the safety of my vehicle and the potential for further complications. Given these circumstances, I am requesting assistance from the NHTSA in resolving this recall issue and guidance on how to proceed with the necessary repairs while the vehicle is registered under my name in the UAE.

Latest negative Kia Optima car reviews

  1. Reese Tillman 2025-05-29

    Vehicle year: 2004

    The 2004 Optima has a known issue with the headlamp lenses, which can develop a cataract-like appearance over time. Unfortunately, I discovered this problem too late and was refused warranty coverage by the dealer. They strung me along by replacing light bulbs instead of addressing the root issue, which ended up costing me more money. I still like Kia as a brand, but I would advise others to check their vehicles for this issue before their warranty expires. Due to my poor experience with the service network, I plan to trade for a different brand next time.

  2. Alvah Ebert 2025-05-28

    Vehicle year: 2004

    I purchased this car after my previous one was totaled by a falling tree. Although it turned out to be a lemon, I managed to get the problems fixed. While the Optima's Mitsubishi motor was loud and slow, the suspension was responsive yet soft. Unfortunately, the doors have a tendency to lock themselves whenever I get out of the car, even when my hand is nowhere near the lock switch. Additionally, the left headlight was poorly replaced, with a cracked lens and broken brackets, and a carpenter screw was drilled into the rubber seal and bumper to keep it in place. I only recommend this car if you're on a tight budget and unable to find a Honda or Toyota in your area. Just be aware that you may encounter problems sooner or later.

  3. Jed Beahan 2025-05-23

    Vehicle year: 2008

    I had a bad experience with my Kia. The motor locked up with only 46,688 miles and although they pieced together a new engine, it only ran for 10,000 miles before the oil light started coming on at idle. The car was out of service for 47 days the first time and it has been 3 weeks since the last repair attempt on 1/11/12. As a result, I decided to let the dealer buy the car back and purchased a Toyota Camry instead.

    Hi there! I hope you're doing well. I just wanted to share my experience with my car. I bought it back in 2008 from a private party and it had 120,000 miles on it. Since then, I've put about 60,000 miles on it in 2 and a half years. I've had to replace a few parts, like the power steering pressure hose (upper) and power steering return hose (lower), as well as the starter. But overall, the car has been really solid and reliable, even with over 180,000 miles on it now. The engine still runs smoothly and the AC still blows cold air. The only issue I've noticed is that the transmission shifts a bit erratically and seems to slip a little between gears. But if you're a backyard mechanic like me and work on your own KIA, you can easily access repair manuals online at kiatechinfo_dot_com by entering your car's VIN. Hope this helps!

    I purchased this car brand new with only 7 miles on the odometer. Despite experiencing issues with four different automatic transmissions, I have been able to successfully resolve the matter with Kia by asserting my legal rights. While I have had to replace the head gasket twice and address oil and transmission fluid leaks, I remain confident in the car's overall performance and safety.

    I'm currently leasing an LX, and the deal was too good to pass up. A friend of mine has an Optima from 2011, and he loves it. However, he did have some complaints about the engine and performance, which have been upgraded in the 2015 model. Unfortunately, the passenger front seat is positioned very low and cannot be adjusted upwards, causing some visibility issues for shorter individuals. This seems to be a common complaint for this and other Hyundai and Kia models. Luckily, I was able to find a set of risers online that bolt onto the original set points and raise the seat almost 2 inches. The installation was easy and corrected the problem. The interior is well-appointed and the quality is impressive for the price point. The car looks, feels, and drives like a more expensive model. I have previously owned a BMW and currently own a Honda Accord, and I can confidently say that this car easily competes with both of them at a lower purchase price. Edmunds has done a good review of all the features, and I opted for the Convenience Plus Package upgrade, which includes a rearview camera, acoustically upgraded windows for noise reduction, and a few other goodies. It is definitely worth it, as without the rearview camera, backing up can be difficult due to the high rear end and sharply raked rear window. I have driven this car in monsoon-like rain at night, and the handling, traction control, and fog lamps all served to give me a sense of control and safety. I bought the Sparkling Silver with light grey interior, and it looks sharp at the price point.

    Great car! I just got back from a trip to the coast and it handled the road and curves amazingly. It even averaged 29 miles per gallon, which is not bad at all considering all the hills and such. I really enjoy the ride and how quiet it is. I think Kia is going to give Honda and Toyota a run for their money. Keep up the good work!

    I have a 14 Optima SXL and I love it! If you're looking for a car around $40,000, definitely take a look at Kia. It drives beautifully and the turbo is a must! Also, the fuel economy is great.

    The battery was replaced at 32,000 miles. Additionally, two LED road lamps were installed behind the grill to improve visibility in dead zones on either side of the front projection beams. These lamps are adjustable in 7 different ways for various weather conditions. The 2.4 engine runs perfectly. However, there seems to be an engineering flaw in one of the front headlight housings that allows moisture behind the clear plastic cover. It has been replaced once about 2 years ago, and I plan on having it replaced again just prior to my bumper to bumper 5 year/50000 mile warranty going out. This car is our go-to road car, with 28,000 miles in about 4 years. We recently switched to Mobil 1 5w30 to ensure that our warranty on the drive train will be honored without question, especially since we don't drive this vehicle much. In town mileage is not great, but on the road it is much better, even at higher speeds. This car likes to go, period. It is still comfortable and spacious inside or in the trunk, with no squeaks or leaks. Overall, this car is highly reliable and enjoyable to drive.

    I recently traded in my 03 Rio and a friend exclaimed, 'You went from a KIA to an Infinity??' But no, this is still a KIA! I must say, this car has exceeded my expectations. It has the power of a six-cylinder with the efficiency of a four-cylinder, making it a beast on the road whether I'm trying to pass or just having fun. I opted for the SX turbo with the luxury package and the corners are incredible. The ride is much smoother than I expected, contrary to other comments (were they driving through feathers before?). I still can't believe the power behind it (274HP?!). The interior is incredibly elegant with attention to the driver, and the panoramic roof is just wow. Bumper to bumper, this car will make you feel much richer than you actually are.
