2021 Kia K5

Electrical System

Electrical system failures are notoriously difficult to diagnose and repair, which often results in multiple unsuccessful repair attempts — a key element of a lemon law claim. Reported issues for the 2021 Kia K5 include infotainment malfunctions, battery drain, warning lights, power window failures, and intermittent starting problems. 17 NHTSA complaints have been filed for this category. Owner reports include: “Blower motor stops working for a bit with no ac or heat” (NHTSA Complaint #11712308)

Fuel System

Fuel and propulsion system defects can cause stalling, fuel leaks, or power loss — all substantial impairments of use and safety. The 2021 Kia K5 has generated 14 NHTSA complaints for this defect category. Owner reports include: “The fuel tank malfunctioned while driving. It appeared on my odometer that I had zero gas, once I pulled into a gas station to fill up, I could see the gas pouring out of the tank while the pump was unable to pump any gas due to the pressure coming out of the tank. Bev Smith Kia of Fort Pierce has the vehicle if you would like to inspect it. I also have photos of the melted tank from the dealership. NHTSA Recall Number: 25V-794 The fuel tank expansion/melting risk, fuel leak, or fire risk, put the driver, passenger, and nearby citizens at risk if the car caught fire. Also, the seats have been known to eject with this particular recall. Yes the vehicle was inspected by Bev Smith Kia per my insistence, and instead of fixing it and returning the vehicle, Kia Corporate forced the hand of Bev Smith Kia to confiscate the vehicle due to it being a deadly recall. SC288 Alpha Campaign Failed is what the dealership told me to tell corporate. There were no warning lights when the odometer appeared to have zero miles, it simply went to zero and the backseat became very hot to the passenger. There was no ability to fill the gas tank as the pressure of gas was pouring gas out from the fuel tank and the pump would not add additional gas. This appeared in May of 2025. We took it to the dealership and they said there was nothing wrong with the car. The next time is happened was Sunday [XXX]. The car was taken to Bev Smith Kia dealership that Monday November 24th where it was confiscated by the dealership for the deadly recall that they claimed could never be fixed and Kia would do a buy back. There were no other issues with the vehicle prior to the incident in May of 2025. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)” (NHTSA Complaint #11720975)

Other Systems

The 2021 Kia K5 has generated 14 NHTSA complaints for this defect category. If your vehicle has experienced recurring issues in this area that the dealer has been unable to repair after multiple attempts, you may have a qualifying lemon law claim under California’s Song-Beverly Consumer Warranty Act. Owner reports include: “I am submitting this complaint regarding ongoing and unresolved safety issues with my Kia K5, which I believe are directly related to a known recall involving the ECM (engine control module) and/or fuel system. My vehicle continues to jerk and misfire during acceleration, and it has even stalled at idle on multiple occasions — creating a serious safety concern for myself and others on the road. I have already completed the recommended repairs, including new ignition coils and spark plugs, yet the problem persists. Despite these symptoms aligning with known recall-related issues, Kia of Orange Park (Florida) has refused to fully diagnose or investigate the matter, citing that the recall does not apply in my case. However, the symptoms match those outlined in other ECM/fuel system-related recalls, and this is not the first time this dealership has failed to properly address mechanical concerns. Previously, I had to escalate an A/C issue to Kia Corporate, which only resulted in a resolution after a recall was issued right before my vehicle was set to be returned with the same issue. That situation makes me extremely concerned that my current safety concerns are again being ignored and will only be addressed after a broader recall is issued. I am requesting that the NHTSA investigate this matter, as I am worried this defect may affect other vehicles and poses a safety risk that Kia and its dealerships are not taking seriously. Thank you for your attention and action.” (NHTSA Complaint #11676487)

Powertrain

California Lemon Law — Song-Beverly Act

California’s Song-Beverly Consumer Warranty Act (Cal. Civ. Code §§ 1790–1795.8) is one of the strongest lemon laws in the United States. It protects buyers and lessees of new and certified pre-owned vehicles that develop substantial defects the manufacturer cannot repair after a reasonable number of attempts.

Under Cal. Civ. Code § 1793.22, a lemon law presumption is triggered when any of the following apply to your 2021 Kia K5:

• 4+ repair attempts for the same non-safety defect without resolution
• 2+ repair attempts for a defect likely to cause death or serious bodily injury
• 30+ calendar days out of service for warranty repairs (cumulative, not consecutive)

Once the presumption is triggered, the burden shifts to Kia to prove the vehicle is not a lemon. Under Cal. Civ. Code § 1794(d), Kia must pay your attorney’s fees if you prevail — meaning qualified representation costs you nothing out of pocket.

What You Can Recover

If your 2021 Kia K5 qualifies as a lemon under California law, Kia may be legally required to:

• Repurchase your vehicle — Full refund of your down payment, all monthly payments, registration fees, and incidental costs (towing, rentals), minus a mileage offset for miles driven before the first repair attempt
• Replace your vehicle — Provide a new, comparable vehicle at no cost to you
• Pay your attorney’s fees — Under § 1794(d), Kia pays all legal fees if you prevail
• Civil penalty up to 2x damages — If Kia willfully violated the Act, courts may award double the actual damages

Steps to Protect Your 2021 Kia K5 Claim

Step 1: Document every repair visit. Keep all repair orders, work orders, and dealer invoices. Each visit counts as a repair attempt, even if the dealer says nothing is wrong.

Step 2: Keep returning for repairs. You must give Kia a reasonable opportunity to fix the defect. Visit different authorized Kia dealers if needed and ask for written documentation of each visit.

Step 3: Contact a California lemon law attorney. Once you believe the threshold has been met — 4 attempts for non-safety defects, 2 for safety defects, or 30 days out of service — contact an attorney for a free case evaluation. Under § 1794(d), Kia pays your fees if you win.

Step 4: Send a demand letter. Your attorney will send Kia a formal demand letter. Most California lemon law cases resolve through negotiation without going to trial.

2021 Kia K5 Lemon Law Questions

How many repair attempts qualify my 2021 Kia K5 as a lemon?

Under Cal. Civ. Code § 1793.22, four or more repair attempts for the same non-safety defect, or two attempts for a safety-related defect, triggers the lemon law presumption. Additionally, 30 or more cumulative days out of service qualifies regardless of the number of repair attempts.

Does Kia pay my attorney fees?

Yes. Under Cal. Civ. Code § 1794(d), Kia is required to pay your reasonable attorney’s fees and court costs if you prevail in a lemon law claim. This means qualified lemon law representation is free to you if your case succeeds.

Can I file a lemon law claim without an active recall?

Yes. A recall is not required to file a lemon law claim. The Song-Beverly Act covers any substantial defect that impairs the use, value, or safety of the vehicle that the manufacturer cannot repair after a reasonable number of attempts. NHTSA complaints support the claim by establishing a pattern, but are not a prerequisite.

What is the time limit to file a lemon law claim for my 2021 Kia K5?

California lemon law claims are generally subject to a four-year statute of limitations from the date you discovered or should have discovered the defect. However, you must still be within the manufacturer’s original warranty period when the defect first appears. Contact an attorney promptly to preserve your rights.
