Why was the Haima S7 discontinued?
1 Answers
Haima S7 was discontinued due to severe engine malfunctions. In terms of safety, the Haima S7 was equipped with dual airbags, ABS+EBD+BOS electronic assistance systems. For child safety, it also featured ISOFIX child seat anchors and child locks. The comfort and convenience features were not particularly abundant but sufficient for daily driving needs. The reasons for engine surging are as follows: 1. High engine idle speed. 2. Improper adjustment of the throttle cable or throttle position sensor, resulting in excessively high main oil circuit pressure. 3. Delayed upshifting. 4. Cracked or detached vacuum hose of the vacuum throttle valve. 5. Malfunction of the main oil circuit pressure regulator, causing excessively high main oil circuit pressure. 6. Stuck damper piston, failing to provide damping. 7. Missing one-way valve steel ball, causing rapid engagement of shift actuators (clutch or brake). 8. Slipping of shift actuators. 9. Malfunctioning oil pressure solenoid valve. 10. Faulty ECU.
