If the transmission of Buick Excelle is leaking oil, do not continue to use it. It is recommended to directly go to a car 4S store or repair shop for professional inspection and maintenance to prevent safety hazards during use. There are many reasons for transmission oil leakage, mainly including natural aging of seals, impact on the transmission, poor assembly process, quality issues, etc. The specific situation should be checked by professionals. Excelle is a car launched by SAIC General Motors, featuring a high-strength and lightweight body design with high-strength steel accounting for up to 65%. It is also equipped with airbags as standard: front dual airbags, front side airbags, and side head airbags. Based on the standard ESP electronic stability control system, Excelle also adds electronic safety assistance systems such as HSA hill start assist system and SLSC straight-line stability control system.

Upon noticing transmission oil leakage, I immediately advised the owner to check the source of the leak. The most common causes could be aging seals or loose oil pan bolts, leading to oil seepage. First, park the car on level ground, open the hood, and inspect under the transmission for any oil stains. If there are oil drips on the ground, measure the oil level to see if it's too low. If you can't add new oil temporarily, you might drive cautiously to a nearby repair shop, but avoid long-distance driving as low transmission oil can damage internal components. Visit a 4S shop or reliable repair facility as soon as possible for inspection. They have specialized tools for diagnosis, typically involving replacing seals or tightening bolts, which costs a few hundred yuan. Don’t neglect regular maintenance—check the transmission oil quality annually to prevent such issues.

Last time my old car had a similar issue - I heard abnormal noises from the transmission when starting, and noticed oil stains on the ground when I looked down. I immediately searched online and suspected it might be a failed oil seal or cracked pipeline. I drove straight to my trusted repair shop where the mechanic used a lift to inspect it, and ultimately spent over 300 yuan to replace new gaskets to fix it. I advise you to address it early, otherwise excessive oil leakage could cause the transmission to overheat and seize up - replacing the entire unit would cost tens of thousands. After repairs, remember to conduct regular inspections. For older cars like the Excelle, seals are prone to aging - I recommend changing the transmission fluid every two years to extend component lifespan. Driving safety comes first, don't lose big for small gains.

Transmission oil leakage is very dangerous. If I notice it, I will stop the car immediately for inspection. First, turn off the engine and check if oil has leaked onto the road surface. If the oil level is too low, do not force the vehicle to drive, as an overheated transmission may lead to loss of control. It is recommended to quickly contact a professional technician for inspection and repair, as the leakage is likely caused by issues with seals or connections. Regular maintenance is essential to avoid driving long distances with an oil leak. Safe driving is the top priority—do not delay repairs.
