Problem overview

Some Toyota Tundra owners report experiencing fuel economy issues, including MPG significantly lower than the manufacturer's claims, particularly noted in the 2019 model, which has been criticized for having the worst fuel economy in its class. These owners often find that factors such as low tire pressure contribute to decreased fuel efficiency due to increased rolling resistance. Additionally, fuel injector problems can lead to symptoms like rough idle, misfires, and illuminated check engine lights, further impacting fuel economy. Furthermore, alignment problems are reported to affect fuel efficiency, with proper wheel alignment being crucial for optimal performance. Owners are advised to monitor tread wear records and consider improved alignment specifications from Toyota to address these issues effectively. Regular maintenance and attention to these concerns can help enhance the Toyota Tundra's fuel efficiency and overall performance.
