Why does the gear shift knob of the 14th-generation Sylphy get hot?
2 Answers
This situation is normal, regardless of winter or summer, though the heat sensation tends to be less noticeable in winter. Below are the relevant explanations: 1. Reason: The gear position indicators (such as P, R, N, D) at the gear shift knob are illuminated by bulbs, which require heat dissipation. Therefore, this phenomenon occurs when the ignition is turned on; otherwise, it would be abnormal. Additionally, if the area feels excessively hot or the surrounding parts are affected, it is recommended to have the vehicle inspected at a repair shop, as it could indicate issues like an overheated catalytic converter in the chassis. 2. Powertrain: The vehicle is equipped with Nissan's HR16 star engine, which has now evolved to its third generation. Each generation of the HR16 engine features core technologies that lead the industry.
I drive a 14th-generation Sylphy and often notice that the gear shift lever gets hot. The main reason is the heat conduction from the transmission and engine, as the gear shift lever is directly connected to the transmission. Prolonged driving in congested areas causes heat to accumulate and rise. Additionally, there may be exhaust pipes or wiring harnesses near the gear shift lever. If the heat insulation material is aged or damaged, heat can more easily transfer to the lever. Overheating of the electronic gear shift module could also cause issues, such as sensor damage or wiring short circuits. This design in the Sylphy is more noticeable in summer. I feel that if the temperature is unusually high when touched immediately after parking, it's time to check the transmission fluid and heat insulation layer. During normal driving, avoiding peak-hour congestion and improving ventilation can help reduce heat buildup, but these are only temporary solutions. Ensure timely diagnosis at a repair shop.
