What owners report
My 2018 Kia Niro had the Hydraulic Clutch Actuator (HCA) replacement in 2024 due to a recall. About two years later, it failed again causing the call to completely stop working creating safety issues for me. The car was towed to the dealership but Kia refused to pay for the fix. I eventually paid for the fix and requested a reimbursement since my vehicle is directly impacted by Safety Recall Campaign SC276 (NHTSA Campaign 23V534000) due to a critical design defect causing fluid leaks and electrical fire hazards. Kia never responded after initial request for escalation on August 4th, then August 14th, then August 21st and finally a voicemail on September 1st. Under federal safety regulation
The dealership is falsely reporting to Kia Corporate and the NHTSA that Recall SC276 is 'completed' by only replacing a fuse.

They are violating federal recall safety mandates by trying to release a vehicle with an active, un-repaired recall leak.
My kia niro 2018 backup camera takes a few seconds to start up when the vehicle is put in reverse. the time it takes differs from a second to sometimes 5 seconds.

The dealer was contacted and stated that the vehicle was serviced under the recall; however, the vehicle was still inoperable, and additional diagnostic tests were needed. The vehicle was towed to an independent mechanic, and the mechanic discovered that there was no coolant inside the coolant reservoir. The contact attempted to contact the dealer but had not received a reply fro
The vehicle experienced a sudden powertrain failure while driving. A certified Kia dealership diagnostic scan confirmed active Diagnostic Trouble Code (DTC) P17ED (Engine Clutch System) and a physical hydraulic clutch fluid leak around the transmission housing area. These symptoms match the exact criteria of NHTSA Safety Recall 23V534 (Kia Campaign SC276) for the Hydraulic Clutch Actuator (HCA). The manufacturer's defective component leaked fluid, causing direct consequential failure of the internal clutch and transmission assembly. Kia is refusing to remedy this safety campaign failure at 100% zero cost to the consumer, violating federal safety recall mandates by attempting to charge 50% of
