Jan 21, 2021

Remember when owning a Kia meant owning a throwaway car? Not anymore, as they’ve reimagined themselves over the last decade into one of the most desirable brands around. However, even the sought after models have issues.

Does the 2015 Kia Optima engine have a recall?  

Nope, but it does have two other recalls, including some related to the engine. There are also a number of manufacturer communications and consumer complaints related to this vehicle.   

The recalls include:  

  • Hydraulic electronic control unit may short 
  • High pressure fuel pipe may leak

In this article, we’ll cover these recalls in full and provide insight into the related manufacturer communications. These are notices sent to owners and dealerships about maintenance, procedures, or other details that may impact the engine of the vehicle.

We will also note some of the consumer complaints related to this vehicle. Stay up to date on the 2015 Kia Optima engine recalls by using Vehicle History.

Hydraulic Electronic Control Unit May Short

NHTSA Recall ID: 20V519000

In August of 2020, Kia issued a recall notice to owners about the service brakes and hydraulic system. In affected vehicles, the brake fluid may leak into the vehicle’s Hydraulic Electronic Control Unit (HECU). This can lead to an electrical short of the vehicle.

If an electrical short occurs, that can cause the engine to fail and increases the risk of an accident. A secondary issue relates to an increased risk of engine compartment fire. In both cases, those in the car can be hurt.

Kia alerted dealerships to inspect the HECU. They looked for any noticeable brake fluid leaks on the vehicle. If found, they replaced the HECU. These repairs began in October of 2020.

High Pressure Fuel Pipe May Leak

NHTSA Recall ID: 18V907000

This recall was issued in December of 2018. It relates to vehicles that have had an engine replacement. This may have been done outright through a repair, warranty, or due to the Knock Sensor Detection System Product Improvement Campaign.

In these vehicles, a high-pressure fuel pipe that connects directly to the fuel pump may have some damage to it from the engine replacement process. In some cases, there is a misalignment of these components. In others, there is improper torqueing. This can lead to a fuel leak.

Should a fuel leak occur, it may occur near the ignition source. This may increase the risk of fire and injury to those in the car.

Kia notified owners of this problem. They then had dealerships inspect the fuel pipe. If there was any evidence of damage or misalignment, they then had the fuel pump replaced. These repairs began in January of 2019.

Manufacturer Communications

Kia released a large program called the Knock Sensor Detection System Product Improvement Campaign. The goal of this campaign was to respond to claims related to engine failures. A total of 4 million vehicles, including those from Hyundai, were affected by this claim, including the 2015 Kia Optima.

The campaign required dealerships to update the software of the vehicle’s engine so it can detect engine failure sooner. The system is designed to sense vibrations occurring in the engine that are an indication of excessive bearing wear.

Should the engine suffer this type of noise, the software should put the vehicle into a safe operation mode. This mode reduces the vehicle’s acceleration and speed limits to get the driver home or to the dealership for repairs. The goal is to reduce the risk of a more severe engine failure.

This program is not an official recall. It did require updates from the dealership. However, Kia did not address the underlying potential problem related to the engine that would create this type of noise.

Consumer Complaints

It is also important to note the numerous customer complaints related to the 2015 Kia Optima engine. Some of these may be related to the previously mentioned problems. Others have not been addressed by Kia.

One such complaint relates to the engine seizing up without warning. Owners noted they were driving the vehicle, and it suddenly stopped working. This leads to the need for a new engine. Some drivers reported this occurs at high speeds on the highway while others were operating in residential areas.

Some drivers reported not just a knocking or jolting of the car but also jerking and shaking. It can make loud, unexplained noises as well. Most often, drivers are unable to drive these vehicles home. This type of power loss is a common statement in the numerous customer complaints drivers have noted related to the engine.

At this time, there are 321 complaints for the 2015 Kia Optima. Of those, 197 relate to the engine in some way.

How Do You Handle an Open Recall on the 2015 Kia Optima?

Wondering if there will be a new engine recall on the 2015 Kia Optima? You can find out about recent recall updates by visiting the National Highway Traffic Safety Administration (NHTSA) website.

Owners can enter the VIN of the vehicle to pull up a list of all applicable recalls for it. If there are any recalls not completed, the system will display this information as well.

Drivers, or those planning to purchase a pre-owned 2015 Kia Optima can enter just the make, model, and year into the system as well if they do not have the VIN. They can then see all related recalls listed.

In most situations, owners will need to call Kia’s customer service number at 1-800-333-4542 to inquire about the recalls. This will allow for the repairs and service appointments to be scheduled at the right local dealership.

DO NOT BUY THESE PIECES OF JUNK!!!
Please don't buy these Kias. Also, stay away from any of the other c**p cars with the same engines. These 2.0and 2.4's are absolute garbage. Drove mine for less than 3 months and it died, while I was on a roundabout. Totally lost power and just died! The dealer said the oil probably ran to one side of the motor, which triggered a sensor to make shut down. Then proceeded to tell me, Kia told him they won't cover a replacement. That was going to come out of my pocket. Between 6,000 and 7,000 dollars, or possibly "just a tad more." What a crock of c**p. Kia said the software updates weren't done pryor to me purchasing it used, therefore making me ineligible for an engine replacement. I asked for proof that it was never done. They couldn't provide me with the info. I ended up having to push it out of the shop alone, into the lot, and have it towed AR my expense to my home where it still sits, dead, and being paid for for the next 3 years still. Save your money! Kia does NOT care about their customers, or others on the road who may be hurt or killed by their inferior vehicles. Don't be fooled. They just do not. I wish I could give negative stars rating.

A 2015 Kia Optima Engine Seizure ... For A Brand-New Driver
Our teenaged son had just received his driver's license the previous week, and decided to go for a drive over the precarious Altamont Pass when the engine on our 2015 Kia Optima suddenly seized up and died while he was in rush-hour traffic. He was in the third lane (of five) on the uphill incline when it happened, and he managed to coast across the truck lane to safety. He was badly shaken, but made it to safety without incident, and AAA (along with his distraught parents) came to his rescue. If anything had happened to him, we would have been devastated -- he was a few weeks from his 17th birthday. Instead, we've now been battling Kia over the warranty. My money is on Kia to screw us completely.

Engine seized
A week ago my engine on my 2015 Kia Optima EX seized up while driving down the road. I contacted a Kia Dealership and it cost me 300.00 to have it towed. Once it got there they told me it had 2 recalls that I had no idea about. Without these recalls being fixed I was out of luck. How are you suppose to get a recall fixed you have no idea existed. They asked me if I wanted to have them run diagnostics on it and charge me $150.00. Obviously they know should know whats wrong with it with all the numerous complaints. I contacted Kia and I was advised I’m basically screwed. I’m stuck with a car that won’t run and will cost me almost 7,000 to fix. No thanks. Kept your worthless car.

2015 Kia Optima EX
Our Kia shut down on the freeway, no warning. The replacement campaign happened prior to us buying the vehicle, so the sensor software was never updated. We had no way of knowing because it wasn’t an actual recall that was reported as needing to be done, it was a campaign. Needless to say, Kia won’t replace the engine, and I’m out $15,000. I had purchased a 2017 Optima SXL so I would have a commuter in addition to my husbands. Now, I’m worried about that engine also. Kia won’t be getting any more of our money and we’ll be sure to let all our friends and family know how well Kia backs their vehicles. Make a smart investment and just don’t buy Kia.

2015 Kia Optima
I was driving down the road and with no warning the car turn off on me, thinking it was low on fuel and was able to start it again and went to the gasoline station put fuel in and when I tried to start it again it was dead, we replace the starter and a week down the road it did the same thing again it died, Took it to a car shop and they diagnosed a locked engine and said that kia should be able to fix it under a recall. It is at the Kia dealer righty now waiting to get fixed hopefully we don't have to pay out of pocket.

My KIA IS TRASH
My husband and I were leaving from our hotel and 1\3 of mile it died. We towed our are car to the Pensacola dealership and there it sits seven hours away from us. I have called Kia Corporate and they are giving me hell telling me I never did the recalls so I'm not eligible for the engine to be replaced. I still owe on my car and it will cost $5000 to be replace my engine. I don't have that! I'm so upset KIA is awful they should honor these cars when they dam will know the reason these engines are seizing.

2015 Kia Optima motor blown/seized
I saved for 3 years to purchase a car (2015 Optima) for my son on his 17th birthday. As a single mom, that wasn’t easy. The other day while he was driving home from his part time job, the car just died for no reason whatsoever. Had it towed to a mechanic and was told the motor blew. Now I’m out the $5,000 I worked so hard to save and no car for my son. Can’t stop crying 😭 You live and learn… never buy Kia under ANY circumstances! s**t company!

It left me on the side of the road!
I have a 2015 Kia Optimawith just a little over 85,000 miles on it, and I change my oil every 3000 miles. It just went dead on me and I was told that it had a rod knocking in the motor. I have the car at the dealeship now and I hope they will tell me something tomorrow. If Kia doesn't stand behind their car, then I am going to repost this on every social media I can find for the next year.

Fixed
My 2015 Kia Optima also had engine fa ilure but I had it towed to the dealer and they said I was the 8th car in line for an engine replacement. So they got a rental car for me for the 2 weeks it took to replace the engine. They also replaced the starter and the fuel rail. They told me I have a lifetime replacement warranty. Call the dealer
