2018 Kia Soul Problems & Complaints

Common problems: Drivers of the 2018 Kia Soul have reported various issues, particularly with the vehicle’s engine, powertrain, and electrical systems.

The 2018 Kia Soul has been the subject of three recalls by the National Highway Traffic Safety Administration (NHTSA).

These recalls address a potential problem with the Air Bag Control Unit (ACU) cover. The cover might come into contact with a memory chip on the printed circuit board, potentially damaging the electrical circuit.

The other two recalls only affect the 2018 EV and involve a fire risk for the high-voltage battery pack and unintended movement when the vehicle is in park.

Read on to learn more about the safety concerns related to the 2018 Kia Soul.

Common 2018 Kia Soul Problems

• Engine: Excessive oil consumption, knocking noise, stalling, engine failure, sputtering
• Powertrain: Loss of power, transmission stalling, hesitation, acceleration issues, rough idle, unintended movement in park
• Electrical System: Starter issues, warning lights, cruise control problems, dead battery

2018 Kia Soul Engine Problems

The 2018 Kia Soul may be vulnerable to engine-related issues. Numerous drivers have reported excessive oil consumption, where vehicles consume oil at an unusually high rate. If left unchecked, this issue can lead to more severe engine damage over time.

In some cases, Kia drivers have experienced complete engine failure, a serious problem that often necessitates costly repairs or even a full engine replacement.

This failure can be particularly devastating and has been linked to catastrophic engine damage, which usually requires an entire engine replacement.

If you own a 2018 Kia Soul and are encountering any of these issues, you should have your vehicle inspected by a professional mechanic.

Addressing these problems early can help prevent further damage and ensure your vehicle’s safety and reliability.

2018 Kia Soul Powertrain Problems

The 2018 Kia Soul has been associated with several powertrain issues, as reported by owners. One of the most common problems involves difficulties with shifting gears properly, and in some cases, complete transmission failure.

Engine and transmission stalling have also been reported, where the engine or transmission fails to maintain power or stalls entirely.

This issue is often related to underlying transmission problems and can be particularly dangerous if it happens while the vehicle is in motion.

2018 Kia Soul Electrical System Problems

The 2018 Kia Soul has been associated with several reported electrical system problems, including starting problems, where the vehicle often fails to start on the first attempt.

Many drivers have found themselves needing to try multiple times or resort to a jump start to get their car running.

Owners have also reported various warning lights turning on without any apparent reason. This can be confusing and alarming, as it’s unclear whether the warning lights indicate a genuine issue or if they are simply malfunctioning.

The 2018 Kia Soul appears to have issues in its cruise control system as well, where it can surge unexpectedly, causing the vehicle to accelerate without input from the driver.

The 2018 Kia Soul has also been subject to a recall for electrical issues affecting EV models. Vehicles equipped with an E400 battery may experience an electrical short-circuit while driving, potentially leading to significant safety hazards.

Kia issued owner notification letters on August 18, 2023, offering to replace the affected batteries free of charge. The NHTSA’s campaign number for this recall is 23V-218.

In addition to the previously mentioned issues, the 2018 Kia Soul EV models have been included in NHTSA recall 23V-724 due to a defect in the parking mechanism.

This defect can cause unintended vehicle movement when the gear shift lever is in the “Park” position and the parking brake is not applied while the vehicle is powered on.

This issue increases the risk of a crash. Kia has addressed this by updating the electronic control unit as part of a recall fix.

Battery problems are another electrical issue reported frequently in the 2018 Kia Soul. As the battery ages, it may lose its ability to hold a charge, making it difficult to start the car or preventing it from starting altogether. This issue can be exacerbated by extreme temperatures or underlying electrical system defects.

Kia Soul Complaints

NHTSA Complaint

“My vehicle randomly started making a knocking noise. We took it to our local mechanic who stated he has seen a lot of these come from the Kia line lately. the knocking noise comes from the rods. He said the cost to get this repaired would be $4,000-$5,000, since the bottom portion of the engine would need to be replaced. This car is not driveable.”“My vehicle randomly started making a knocking noise.

NHTSA Complaint

“My Goddaughter has had random starting problems with the 2018 Kia Soul plus, that I bought her. If you turn the key you hear a click but it won’t start until you try several times. She has had to get a jump on occasions. We bought a new battery, thinking that was the problem, but that didn’t solve the issue. Taken car to the dealership several times, but they say that they can’t find a problem. She get nervous everytime she goes somewhere and cut the car off, thinking she’s gonna get stranded.”

Cars.com Complaint

“Broke down less than 1 year after purchasing it (was NEW when purchased). Search “Kia Stutters/Sputters” or “Kia Engine Hesitation” or “Kia Idles Hard” or “Acceleration Issues” or “Kia Threatens to Stall”. You will literally see hundreds of issues – don’t make the same mistake I did. Worst experience ever – huge time/money waste and mental/emotional drain (especially when you think you’re going to get into an accident every time it stutters).”

Advocating Your Rights Under the Lemon Law

If you’re dealing with persistent problems with your 2018 Kia Soul, you may have options for resolution under the lemon law.

This law is designed to protect consumers who purchase or lease vehicles that fail to meet expected quality and performance standards while still under warranty.

If your Kia Soul has been repeatedly repaired for the same issue, and that problem significantly affects the vehicle’s safety, use, or value, you could be entitled to legal remedies.

These remedies vary depending on the specific lemon law in your state but generally include options such as a refund, a replacement vehicle, or monetary compensation.

It’s important to note that if you receive a refund, the manufacturer might deduct a fee for the time you were able to use the vehicle without issues.

Similarly, if you opt for a replacement vehicle, you may be responsible for covering any difference in price.

In most lemon law cases, the vehicle manufacturer is required to pay your legal fees and costs if your claim is successful.

This provision allows you to seek a solution without worrying about the expense of legal representation, making it a practical and financially sound decision to address the ongoing issues with your 2018 Kia Soul.
