Toyota Kirloskar Motor, a major player in the Indian automotive market, has taken a significant step by temporarily stopping the deliveries of its popular utility vehicles – Innova Crysta, Fortuner, and Hilux. This decision stems from the discovery of discrepancies in the horse power output certification testing of diesel engines in some models.


Investigation and Findings


  • Development and Testing: Toyota Motor Corporation had entrusted Toyota Industries Corporation (TICO) with the development of its diesel engines.
  • Irregularities Found: TICO’s special investigation uncovered irregularities in the horsepower output certification testing for three diesel engines. Notably, the performance during certification testing was measured using an Electronic Control Unit (ECU) with different software from the one used in mass production.


Global Statement by Toyota Motor Corporation


  • Acknowledgment of Discrepancies: In a global statement, Toyota Motor Corporation acknowledged the inconsistencies in the certification testing of its diesel engines.
  • Software Variation: The statement highlighted that the horsepower output was measured using different software during certification testing, diverging from the software used for mass production.


Impact on December Car Sales


  • Sales Figures: In December 2023, Toyota reported the sale of 21,372 units across its range.
  • Best-selling Model: Among the eight models sold, Innova Crysta stood out as the top-selling Multi-Purpose Vehicle (MPV).
