NHTSA Complaint #11703866 — 2017 HYUNDAI TUCSON

I’m submitting this complaint to report what appears to be a serious safety-related engine issue in my 2017 Hyundai Tucson Sport 2WD with the 1.6L DI Turbo engine [T-GDI GAMMA]. I’m aware of NHTSA Recall 21V-727, which covers 2017 Hyundai Tucson models with the 2.0L engine for premature engine bearing wear. The symptoms covered by that recall are nearly identical to the symptoms my vehicle is now showing. My VIN shows no open recalls or service campaigns on Hyundai’s website, but the problems I’m experiencing match those found in many other consumer reports for this same year, make, and model. My vehicle has only 80,000 miles and has had regular maintenance. Examples include loud knocking from the engine that rises and falls with RPM, and metal shavings in the oil. One complaint that reflects the same pattern can be found in NHTSA ID 11680114, which describes engine knocking and metal debris with no warning lights or alerts. My vehicle has also shown no warning indicators. These issues pose a safety risk because they can lead to sudden engine failure while driving. Based on the volume of similar complaints and the overlap with the existing recall, I’m concerned that the defect may affect more than the engines currently covered under 21V-727. I’m requesting that NHTSA review this matter and determine whether Hyundai should extend or expand the recall to include vehicles equipped with the 2017 Hyundai Tucson Sport 2WD 1.6L DI Turbo DOHC 4cyl. Please investigate this issue and hold Hyundai accountable if these defects extend beyond the vehicles already listed.
