NHTSA Complaint #11518242 — 2015 HYUNDAI ELANTRA

Engine stalled while going at-speed on major highway; high risk of crash if not restarted in time. Continuous repeating stalls. Hyundai inspected car twice; failed to fix the problem on the first attempt, refused to replace engine alleging that maintenance was negligent due to residue inside motor. Hyundai did not report any residue on the first inspection, and likely did not inspect engine thoroughly when stalling was initially reported to their mechanics. Odd noises from engine present for months prior to stalling.
