The reasons why a car fails to engage gear after being exposed to sunlight are as follows: 1. Positioning component failure: It may be due to the failure of the positioning component of the shift lever's positioning ball head, causing the shift lever to rotate freely around its own axis and making it impossible to accurately control the gear. 2. Worn spherical working surface at the lower end of the shift lever: The spherical working surface at the lower end of the shift lever may be worn out, preventing the shift lever from controlling the fork or the fork head's slot, leading to failure in gear engagement and disengagement. 3. Incomplete clutch separation: The clutch may not fully separate, resulting in gear engagement failure. 4. Loose or damaged fork: The fork may be loose, severely bent, deformed, or worn, causing gear engagement failure.
