NHTSA Complaint #11706903 — 2015 SUBARU XV CROSSTREK

While driving at normal operating speed, the vehicle experienced a sudden and complete loss of engine power with no prior warning. There were no dashboard alerts, warning lights, or check engine indicators before the failure occurred. The vehicle became immediately unsafe to operate and had to be pulled over in a main highway center lane divide. After inspection by a licensed mechanic, it was determined that the engine suffered catastrophic internal failure due to oil and engine coolant mixing. This resulted in complete engine failure and rendered the vehicle inoperable. The vehicle has been properly maintained with all routine oil changes and inspections completed on schedule. There was no indication of overheating or mechanical issues prior to the failure. The condition that caused the failure was not detectable through normal maintenance. The sudden loss of power without warning created a significant safety risk to the driver and surrounding traffic. Due to the nature of the failure, the engine requires full replacement, and both 12v and hybrid batteries were also damaged and require replacement. This incident raises concern regarding a potential latent defect related to the engine or cooling system, particularly given reports of similar issues in this model year.
