NHTSA Complaints · Active Recalls · California Lemon Law Data
The NHTSA tracks consumer complaints, manufacturer recalls, and safety investigations for every vehicle sold in the United States. These publicly available records are a critical resource for California lemon law cases because they establish patterns of recurring defects.
As of June 2026, the NHTSA has logged 185 complaints against the 2021 Kia Soul. Each complaint is filed by a vehicle owner or lessee through the NHTSA’s Vehicle Safety Hotline or online portal at SaferCar.gov. You can review all 2021 Kia Soul complaints directly on the NHTSA complaint database.
The 2021 Kia Soul has generated 185 NHTSA complaints and has 2 active recalls. If your 2021 Kia Soul has experienced a defect that the dealer has been unable to repair after multiple visits, you may qualify for a full repurchase or replacement under California lemon law. Kia pays all attorney fees when we prevail. You pay nothing.
Engine and cooling problems are among the most serious defects under California’s Song-Beverly Act. Owners of the 2021 Kia Soul have reported issues including stalling, overheating, loss of power, rough idling, excessive oil consumption, and check engine lights that return after dealer repairs. With 78 NHTSA complaints on record, this defect pattern is well-documented. Owner reports include: “My 2021 Kia Soul is exhibiting a severe safety defect documented in Recall SC336: frequent, unpredictable stalling in traffic (“Loss of Motive Power”) and audible engine knocking. These symptoms create a high risk of a rear-end collision or being stranded in a dangerous traffic situation. The vehicle is currently at Kia of Streetsboro. Despite being provided with evidence of these active mechanical failures, the dealership is attempting to “remedy” the safety recall based solely on a “Pass” result from the Piston Ring Noise Sensing System (PNSS) software diagnostic. As the TSB SC336 notes that the root cause is physical damage to cylinder walls caused by defective piston oil rings, a software diagnostic “Pass” is not a physical repair and does not address the existing mechanical stalling. I have not received any status updates or communication from the dealership service department since Friday. The dealership is refusing to perform a borescope inspection or open a Kia Techline case to investigate the stalling, effectively denying a proper safety remedy. I am reporting this as a failure of the manufacturer and dealership to provide a safe and effective remedy for a known life-safety defect. The car remains unsafe to drive.” (NHTSA Complaint #11724841)
Engine and cooling problems are among the most serious defects under California’s Song-Beverly Act.

With 30 NHTSA complaints on record, this defect pattern is well-documented. Owner reports include: “The contact owns a 2021 Kia Soul. The contact stated that while driving at various speeds, the engine was consuming an excessive amount of engine oil. While depressing the accelerator pedal, there was an abnormal sound coming from the engine. The vehicle was not taken to the dealer or an independent mechanic to be diagnosed. The contact was topping off the engine oil bi-weekly. The contact related the failure to NHTSA Campaign Number: 25V099000 (ENGINE AND ENGINE COOLING) for which the VIN was included. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 150,000.” (NHTSA Complaint #11714541)
The 2021 Kia Soul has generated 10 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: “Paint is peeling on the roof of my 2021 Kia Soul – for no reason. I have read that other KIA owners have this problem and Kia is not taking responsibility for this.” (NHTSA Complaint #11696108)
Powertrain and transmission defects directly impair the vehicle’s core function and are generally considered substantial defects under California lemon law. Owners of the 2021 Kia Soul have reported harsh shifting, shuddering, slipping, and transmission warning lights. 7 NHTSA complaints have been submitted for this defect category. Owner reports include: “In April 2023 I purchased a 2021 Kia Soul. I had no issues at all with my Used Kia Soul. In Nov 2023 I was in an accident. I hit a deer and that did cause damage. My insurance company fixed it. I got my car back in Dec [XX], 2023 with approximately 96,000 miles on it. A few days later on my way to work. I entered the highway the car was running fine at 70mph then all of a sudden it lost power.. No power in the middle of the busy Atlanta Highway!! I was able to coast onto the shoulder. At that point I turned the car off. Turn the car back on to see if I was able to get it into Drive. Unfortunately that didn’t work my car didn’t move at all. I had to call the tow company get it towed back down to the collision shop. Only for the collision shop to send it to a Kia dealership. My car had been at the dealership for a few weeks. Today is February 8. I got the notice from my insurance company that the Kia dealership said I had metal shavings inside of my transmission and fluid. How does that happen? Then I decided to do some research and I noticed that this transmission is a problem. Not only a problem for people that are struggling with bills and finance charges but a problem with the manufacturing of this product. I’m not sure why there isn’t a recall on this transmission, if I was unable to get off of the highway I would have been hit. What is being done about this problem? To add injury to insult my 100,000 mile warranty isn’t any good because I’m the second owner of the car. I don’t understand how this isn’t a safety recall issue.

Brake defects affecting safety may qualify for California’s two-repair threshold under Cal. Civ. Code § 1793.22, which applies to defects likely to cause death or serious bodily injury. The 2021 Kia Soul has generated 3 NHTSA complaints related to braking, including ABS failures, grinding, reduced stopping power, and warning lights. Owner reports include: “I am filing this complaint to report a serious safety failure involving the service braking system and the failure of Forward Collision‑Avoidance Assist (FCA) and Automatic Emergency Braking (AEB) on my 2021 Kia Soul. During an imminent collision event, the vehicle failed to brake as expected, and FCA/AEB did not activate, despite conditions that should have triggered emergency braking. This created an extremely dangerous situation and placed me and other motorists at risk of serious injury or death. The vehicle is currently subject to an active recall and has now been inoperable at the dealership for approximately one month under the lemon law process. The failure involved federally regulated safety systems, not supplemental or convenience features. I reported this incident to Kia America Customer Care, but the manufacturer has declined to conduct a manufacturer‑level safety investigation unless I personally pay for removal and shipment of the ACU/Event Data Recorder (EDR). Kia America has also declined to provide any transportation assistance while the vehicle remains unsafe and inoperable and has referred the matter back to the dealership and my insurance instead. Kia America has stated in writing that they rely solely on dealerships for diagnosis and repair and that they will not investigate further unless I incur additional costs. This refusal to independently investigate a braking system failure raises serious safety concerns, particularly given the potential risk to other drivers if this defect is not addressed. Due to the prolonged loss of use of the vehicle, I am experiencing significant financial hardship and risk to my employment, as I can no longer afford a rental vehicle. I am submitting this complaint so that NHTSA is aware of a potential defect involving brake system failure and non‑functioning collision‑avoidance systems on this model.” (NHTSA Complaint #11724786)

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 Soul:
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 2021 Kia Soul 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.
