2020 Kia Niro Lemon Law Case Study — Florida
A 2020 Kia Niro That Spent 110 Days at the Dealer — Same Inverter Cooling Failure, Five Different Visits, Five Different Attempted Fixes
Our client owned a 2020 Kia Niro — Kia's electric crossover utility vehicle — that developed a recurring inverter cooling system failure. The vehicle displayed a "Refill Inverter Coolant" warning on the dashboard repeatedly, and despite five separate repair visits spanning more than a year, Kia's technicians were unable to permanently resolve the underlying defect.
Each visit brought a new attempted fix: first the evaporator core and on-board charger assembly were addressed; then the engine long block and radiator were replaced entirely; then a coolant flush; then a coolant pipe clearing and Kia Connect modem recall. By the fifth visit — 39 consecutive days at the shop — technicians were replacing the traction motor, on-board charger, electric high-voltage pump, electric water pump, and A/C chiller due to corrosion throughout the cooling system. The same warning that appeared at the very first visit had persisted through every major component replacement the dealership could attempt.
The vehicle accumulated 110 cumulative days out of service — more than 7 times Florida's 15-day statutory threshold and more than 7 times the number of repair attempts for the same recurring defect needed to trigger warranty protections. Easy Lemon built the case around the persistent EV drivetrain defect and the overwhelming documented repair history. The result: a $4,000 Cash and Keep settlement — our client kept the repaired vehicle and received $4,000 in compensation. No attorney fees paid.
What Went Wrong
- Recurring "Refill Inverter Coolant" warning: The dashboard warning indicating inverter coolant system failure appeared at every single repair visit — five times in total. The inverter cooling system is a critical component in the Kia Niro's electric drivetrain, responsible for regulating temperature in the high-voltage battery inverter and related components. A failure here directly affects the vehicle's ability to operate safely and reliably
- Evaporator core failure and OBC work (Visit 1): The first visit — 36 consecutive days — found a leaking evaporator core, which was replaced, along with work on the on-board charger (OBC) assembly. Despite the length of this repair, the cooling system warning returned
- Engine long block and radiator replacement (Visit 2): The second visit — 26 days — escalated to a more serious diagnosis: debris found in the radiator, requiring replacement of both the engine long block and the radiator. A TAC (Technical Assistance Center) case was opened, indicating the dealership escalated the recurring failure to Kia's engineering team. The warning returned again
- Coolant flush, pipe clearing, and modem recall (Visits 3 and 4): Visits 3 and 4 brought progressively less invasive repairs — a coolant flush at visit 3 (issue could not be duplicated), and at visit 4 a restriction found in the low-conductivity coolant pipe, which was cleared and refilled. A Kia Connect modem recall was also performed at this visit
- Traction motor, OBC, pumps, and A/C chiller replaced — corrosion found throughout (Visit 5): At the fifth and final visit — 39 more consecutive days — technicians discovered systemic corrosion throughout the cooling system. The response was comprehensive: the traction motor, on-board charger, electric high-voltage pump, electric water pump, and A/C chiller were all replaced in a single service event. This was Kia's most extensive repair attempt, replacing the majority of the EV drivetrain cooling circuit
Five Visits, 110 Days — The Same Inverter Cooling Warning That Wouldn't Quit
Visit 1 — June 10–July 15, 2024 (36 Days): A/C Not Cooling, Inverter Coolant Warning — Evaporator Core and OBC Replaced
Our client first brought the Niro in for service in June 2024. The vehicle presented with two complaints: the A/C system was not cooling properly, and a "Refill Inverter Coolant" warning had appeared on the dashboard. The vehicle history report confirmed the vehicle was in service for 36 consecutive days. Technicians found a leaking evaporator core, which was replaced, and also performed work on the on-board charger (OBC) assembly. Despite these component replacements, the inverter coolant warning would return.
Visit 2 — July 12–August 6, 2024 (26 Days): Inverter Coolant Warning Returns — Debris in Radiator, Engine Long Block and Radiator Replaced
Shortly after the first repair, the "Refill Inverter Coolant" warning reappeared on the dashboard. The vehicle returned to service in mid-July 2024. This time, a TAC (Technical Assistance Center) case was opened — meaning Kia's engineering team was formally engaged to assist the dealership in diagnosing the recurring fault. Technicians found debris in the radiator and proceeded with an extensive repair: both the engine long block and the radiator were replaced. The vehicle was out of service for 26 additional days. The cumulative total stood at 62+ days after only two visits — already more than four times Florida's 15-day threshold.
Visit 3 — December 27, 2024–January 2, 2025 (~7 Days): Inverter Coolant Warning Again — Could Not Duplicate, No Repairs Performed
In late December 2024, the inverter coolant warning reappeared for a third time. The vehicle was brought in on December 27 and not returned until January 2, 2025 — an additional 7 days out of service. On this visit, technicians were unable to duplicate the warning and found the coolant fluid level to be full. No repairs were performed. While the vehicle was returned, the underlying cooling system issue remained unresolved — as evidenced by its return just months later.
Visit 4 — May 1–2, 2025 (2 Days): Inverter Coolant Warning Returns Again — Coolant Pipe Restriction Found, Kia Connect Recall Performed
By May 2025, the "Refill Inverter Coolant" warning had appeared for the fourth time. Technicians diagnosed a restriction in the low-conductivity coolant pipe, which was causing poor coolant flow through the EV drivetrain circuit. The coolant was drained and flushed, the pipe restriction was cleared, and the reservoir was refilled. An air bleed procedure was completed using the KDS diagnostic tool. The Kia Connect modem recall was also performed at this visit. The vehicle was returned in 2 days — but the cooling system's fundamental problem had not been cured.
Visit 5 — June 9–July 17, 2025 (39 Days): Corrosion Discovered Throughout Cooling System — Traction Motor, OBC, Both Pumps, and A/C Chiller All Replaced
The fifth and final repair visit arrived in June 2025 — the most comprehensive and revealing of all. The "Refill Inverter Coolant" warning had returned yet again. This time, technicians discovered something more serious: corrosion throughout the EV cooling system. The extent of the damage required replacement of five major components in a single service event: the traction motor, on-board charger, electric high-voltage pump, electric water pump, and A/C chiller. The vehicle was out of service for 39 consecutive days. When the fifth visit ended, the cumulative out-of-service total had reached 110 days — 7.3 times Florida's 15-day lemon law threshold. Easy Lemon filed its demand and secured a $4,000 Cash and Keep settlement.
Why This 2020 Kia Niro Was Entitled to Compensation Under Florida and Federal Warranty Law
This case presented an unusually strong evidentiary record: five repair visits, all addressing the same recurring defect, totaling 110 days out of service, with a TAC escalation at visit 2 confirming that Kia's own engineering team had been unable to resolve the issue.
- 110 days out of service — 7.3× Florida's threshold: Florida Statutes § 681.104 requires 15 or more cumulative out-of-service days to trigger lemon law protection for vehicles within 24 months or 24,000 miles of delivery. This Niro accumulated 110 cumulative days — a figure that dwarfs Florida's threshold. Even a single visit (Visit 1 at 36 days, Visit 2 at 26 days, or Visit 5 at 39 days) would individually exceed the entire statutory requirement
- Five repair attempts for the same recurring defect: Beyond the day count, Florida lemon law is also triggered by 3 or more repair attempts for the same defect without successful resolution. The "Refill Inverter Coolant" warning and the underlying EV cooling system failure appeared at every single visit — five times, each time prompting a different attempted repair. This is a textbook same-defect recurrence pattern
- Federal Magnuson-Moss Warranty Act: The Magnuson-Moss Warranty Act (15 U.S.C. § 2301 et seq.) provides a federal warranty protection framework that applies to any vehicle covered by the manufacturer's express written warranty. Kia's powertrain warranty on the Niro EV extends to 10 years or 100,000 miles — a coverage period that encompasses the repair visits documented in this case. Kia's failure to repair the recurring inverter cooling system defect within a reasonable number of attempts constitutes a breach of express warranty under federal law
- TAC escalation confirms systemic failure: At Visit 2, the dealership escalated the repair to Kia's Technical Assistance Center — Kia's internal engineering escalation process for repairs that dealership technicians cannot resolve on their own. This escalation is significant: it demonstrates that even Kia's own engineering resources were engaged with this recurring failure and still could not produce a permanent fix
- Corrosion finding confirms systemic defect: The discovery of systemic corrosion throughout the cooling circuit at Visit 5 — more than a year after the first repair — is consistent with a manufacturing or design defect in the Niro's EV drivetrain cooling system. Corrosion that propagates through multiple components (traction motor, OBC, pumps, chiller) is not a random failure; it reflects a systemic materials or design issue that Kia was unable to prevent through individual component replacements
How Easy Lemon Fought for Our Client
Free Case Evaluation
We reviewed the vehicle history report and available repair records, mapped the five repair visits and 110 cumulative out-of-service days, and evaluated the case against Florida's lemon law thresholds and the federal Magnuson-Moss Warranty Act. With five visits for the same recurring defect, a TAC escalation on record, and 110 days out of service, this was a strong warranty breach case.
Documentation & Case Construction
We assembled the repair record across all five visits, calculated cumulative days precisely (36 + 26 + 7 + 2 + 39 = 110 days), and documented the identical "Refill Inverter Coolant" warning present at each visit. The TAC escalation at Visit 2 was a particularly significant piece of evidence — it demonstrated that Kia's own engineers had been unable to resolve the issue. We also documented the progression from individual component failures to systemic corrosion across the entire cooling circuit.
Formal Demand to Kia America
Easy Lemon filed a formal legal demand against Kia America under the federal Magnuson-Moss Warranty Act and Florida consumer protection laws, citing the five repair attempts for the same recurring defect, 110 cumulative days out of service, TAC escalation confirming Kia's own engineering team had engaged with the unresolved failure, and the final discovery of systemic corrosion requiring replacement of nearly the entire EV drivetrain cooling circuit.
$4,000 Cash and Keep Settlement Negotiated
Easy Lemon negotiated directly with Kia America's legal team. With 110 days of documented out-of-service time, five visits for the same defect, and a vehicle that had required replacement of its traction motor, engine long block, on-board charger, both electric pumps, evaporator core, radiator, and A/C chiller — Kia agreed to a $4,000 Cash and Keep settlement. Our client kept the repaired vehicle and received $4,000 in compensation.
Settlement Finalized — $4,000 Cash and Keep
Our client received $4,000 in compensation while retaining ownership of the Niro. With the extensive drivetrain component replacements completed at Visit 5, the vehicle was in substantially better mechanical condition than it had been throughout the year of recurring failures. Attorney fees were covered under the terms of the settlement. Our client paid nothing out of pocket.
