Why does the all-new Tucson experience sudden jerks during acceleration?
3 Answers
The sudden jerks during acceleration in the all-new Tucson may be caused by the vehicle being in the break-in period, where both the power output and component engagement are not at their optimal levels. Below are the specific details about the Tucson: Model Positioning: As Beijing Hyundai's first SUV, the Tucson measures 4475x1850x1655 (LxWxH in mm). Powertrain: It is equipped with a 1.6T + 7DCT powertrain combination, along with features such as EPB + AUTO-HOLD, all-wheel drive (4WD), front MacPherson strut + rear multi-link suspension, and electric power steering system.
When driving the all-new Tucson, sudden jerking during acceleration is quite common, feeling like the car lurches forward uncomfortably. This issue is often related to the automatic transmission, such as insufficient hydraulic pressure in the dual-clutch system or delayed shifting causing roughness. It could also be due to an aging fuel pump leading to delayed fuel supply, or engine sensors sending incorrect signals, causing the computer control to malfunction. In daily driving, checking the transmission fluid level and air filter blockage is the first step. Ignoring it may damage transmission components in the long run, so I recommend taking it to a 4S shop for a full inspection, especially scanning for error codes to identify the root cause. Regular maintenance like oil changes can prevent such issues and ensure safe driving.
As someone frequently exposed to Hyundai vehicles, I've noticed that the jerky starts in the Tucson often stem from electronic control system issues. The engine ECU's poor coordination during acceleration or oil pressure fluctuations in the clutch module can cause jerking, feeling like gears are jumping. Spark plug carbon buildup or aging ignition coils can also disrupt smoothness, especially during cold starts. During inspections, use diagnostic tools to read OBD data and confirm sensor values like RPM are normal. Don't overlook checking for driveshaft wear, as it can exacerbate vibrations while driving. Timely repairs prevent minor issues from escalating, benefiting the vehicle's lifespan.
