Toyota Motor posted on Wednesday its first quarterly profit drop in two years as its weaker sales and production issues in two crucial markets - Japan and the U.S. - stalled the Japanese automaker's recent record run. The world's top-selling automaker had been on a record profit run until earlier this year, with its heavy focus on hybrid models helping it benefit from growing consumer interest in more affordable vehicles compared to the costlier battery-powered electric vehicles amid soaring inflation. But quality issues at its truck and bus unit Hino Motors, heavy competition from Chinese brands in the world's biggest auto market, and a now-resolved production suspension of two models in the U.S. have started slowing its sales momentum in recent months. Toyota pledged to reduce incentives and improve production in the second half of its fiscal year to end-March 2025, as it moves ahead with a review of certification and quality related issues.
