The main mechanical issues of rear-wheel drive (RWD) vehicles commonly encountered in Malaysia include insufficient traction, drivetrain failures, and handling challenges. On slippery surfaces or during rapid acceleration, the rear wheels are prone to slipping due to concentrated driving force on the rear axle, resulting in reduced traction. Extra caution with throttle control is particularly necessary during monsoon seasons. For instance, a fractured driveshaft or damaged differential gears can disrupt power delivery, necessitating regular lubrication checks and wear inspections. Additionally, seized brake calipers or clogged hydraulic lines may cause rear brake drag, manifested as restricted wheel rotation, requiring prompt component cleaning or replacement. Regarding spatial configuration, the driveshaft's chassis occupation may compromise rear passenger legroom or boot capacity, while the added system weight marginally increases fuel consumption. Though RWD vehicles demonstrate superior cornering agility, their oversteering tendency demands advanced driving skills, particularly requiring avoidance of abrupt throttle lift-off during high-speed turns. Ultimately, the RWD system appeals to driving enthusiasts but entails elevated maintenance costs and demands greater road condition adaptability.
