NHTSA Complaint #11698099 — 2016 HYUNDAI TUCSON

My 2016 Hyundai Tucson has a severe engine defect that causes excessive oil consumption and poses a safety risk while driving. It constantly throws the P1326 engine issue, which is the knock sensor.The issue is not due to any misuse or neglect on my part. The vehicle consumes approximately one quart of oil per week, and I have been advised by two different Hyundai dealerships not to invest any money into repairs because the engine should be replaced under Hyundai’s extended engine warranty (15 years/150,000 miles).Despite multiple attempts to get the issue resolved over the past year, Hyundai continues to deny the engine replacement, leaving me with no resolution and forcing me to drive an unsafe vehicle.The engine burns an excessive amount of oil and needs frequent refilling to prevent damage.The vehicle has stalled and runs rough at times, creating a safety concern.Both Hyundai dealerships I’ve visited confirmed that this is a known issue and advised me not to spend money on repairs since the engine qualifies for replacement under the extended warranty.Hyundai corporate continues to deny coverage and has not repaired or replaced the engine despite the clear warranty terms.The issue has persisted for nearly a year, and the vehicle continues to deteriorate.I believe this defect poses a serious safety hazard because the engine can fail without warning while driving. The excessive oil consumption also increases the risk of engine seizure, stalling, or fire. I am currently forced to operate the vehicle in unsafe conditions due to Hyundai’s inaction. I am requesting that NHTSA investigate this ongoing engine defect and Hyundai’s repeated denial of warranty coverage for affected Tucson models. Owners should not be forced to drive unsafe vehicles or pay for repairs that should be covered under Hyundai’s extended
