| Engine And Engine Cooling problems |
The engine in my Honda Civic si failed prematurely at 28,677 miles while the vehicle was still within Honda’s 5-year/60,000-mile powertrain warranty. Honda and the dealership denied warranty coverage based on a recorded engine overspeed event of 6,900 rpm that occurred earlier at 19,259 miles. The engine’s rev limiter is 6,600 rpm, meaning the recorded event exceeded the limiter by only 300 rpm. After this recorded event, the vehicle continued to operate normally for approximately 9,400 additional miles with no warning lights, drivability issues, or indication of engine damage. The engine failure occurred suddenly at low mileage without prior symptoms. Honda has not provided clear technical evidence demonstrating how a minor overspeed event of this magnitude, occurring thousands of miles earlier, directly caused the engine failure. This raises concerns about premature engine failure, possible engine defects, and the reliability and durability of the Honda Civic si 1. 5t engine. It also raises concerns about manufacturers denying warranty coverage for failures without clear causal evidence. This failure resulted in loss of vehicle function and significant financial burden. The vehicle has been properly maintained and was operated under normal driving conditions. I am submitting this complaint because premature engine failure at such low mileage may indicate a defect affecting engine durability, safety, and reliability.
The contact owns a 2024 Honda Civic. The contact stated that while driving approximately 15 mph and slowing for a traffic light, the brake pedal was depressed, and the vehicle started shaking violently and then stalled. The contact stated that the check battery warning light was illuminated. The failure was intermittent but became a recurring failure. The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 26,000.
