Complaints for the 2004 Toyota Prius are concentrated in headlight/taillight failures and electrical faults, together accounting for a large portion of the total. Engine and brake issues also appear frequently. The data suggests potential reliability concerns in these areas, though the low confidence level warrants caution.

Top Concerns
  • Headlight/Taillight Failures
  • Electrical Faults
  • Engine Problems
Data note: NHTSA complaints are consumer-submitted and do not confirm a manufacturing defect. The confidence level is Low, meaning the data may not be fully representative. Only one model year was analyzed, limiting the ability to identify trends across years.
