Owner reports include: “Both horns went bad on my vehicle that is less than 2 years old. Dealership said ours is the 5th vehicle they have seen this week with the same issue. They have been unable to determine a cause.” (NHTSA Complaint #11693759)
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 2024 Kia Carnival include infotainment malfunctions, battery drain, warning lights, power window failures, and intermittent starting problems. 7 NHTSA complaints have been filed for this category. Owner reports include: “Horns (high and low) have been replaced 5 times under a warranty. This is a serious safety hazard. Vehicle: Kia Carnival (Model Years 2022–2024) Issue: Repeated horn failure / electrical malfunction Owners of 2022–2024 Kia Carnival vehicles are experiencing repeated horn failures that present a safety concern. Reported symptoms include complete loss of horn function, intermittent operation, delayed response, and in some cases random horn or alarm activation without driver input. When the failure occurs, both the high-pitch and low-pitch horns are often found to be inoperative. Many owners report that dealerships replace both horns, sometimes multiple times, with some vehicles requiring second or third replacements. Kia has acknowledged this issue through a Technical Service Bulletin (ELE-263), which instructs dealers to replace both horns when one fails; however, the bulletin does not identify a permanent root cause or corrective design change. As a result, the issue frequently recurs after replacement. A non-functional or intermittent horn significantly reduces the driver’s ability to warn other road users and avoid collisions, creating a clear safety risk. Given the recurring nature of the failure across multiple model years, this appears to be a systemic defect rather than isolated component wear.” (NHTSA Complaint #11714079)
The 2024 Kia Carnival has generated 5 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: “On 11/12, my 2024 Kia Carnival was parked as my children were getting settled in the vehicle. My son lifted the second-row passenger seat on the passenger side using the handle provided to access the third row. As he did so, the seatback suddenly collapsed forward with unexpected speed and force and locked in the forward position. Nothing broke, and the mechanism did not appear to jam. The seat moved along its normal path, but it did so so aggressively that it crushed my [XXX] daughter’s left leg while she was strapped into her car seat directly next to it. She was asleep, the car was not moving, and the seat feature was being used in a normal way to access the third row. The force of the collapsing seat fractured her left tibia, confirmed by X-ray. She is currently in a medical boot and under a doctor’s care. This vehicle has no accident history and no modifications. We have multiple witnesses (myself and our children), photos of the injury, and a video that shows how fast and forcefully the seat folds. This presents a serious safety risk in a family vehicle where children commonly sit behind folding second-row seats. A seat access mechanism should not be capable of moving with enough force to break a toddler’s bone in a parked vehicle. I am requesting that NHTSA investigate this seat design and its operation in the 2024 Kia Carnival.

The contact stated that the dealer had failed to perform the recall repair correctly because the failure persisted. The manufacturer was notified of the failure, and a case was filed; however, no assistance was provided. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The failure mileage was approximately 25,000.” (NHTSA Complaint #11689092)

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 2024 Kia Carnival:
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.
If your 2024 Kia Carnival qualifies as a lemon under California law, Kia may be legally required to:
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.
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.
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.
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.
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.
