Why does the All-new Tucson experience sudden jerks during acceleration?
2 Answers
All-new Tucson's acceleration jerkiness occurs because the vehicle is in the break-in period, where both power output and component engagement are not at optimal levels. Below are specific details about the Tucson: 1. Vehicle Positioning: As Beijing Hyundai's first SUV, the Tucson measures 4475x1850x1655 (LxWxH in mm). 2. Powertrain: 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.
I've been driving for over ten years and encountered sudden jerking issues when starting the Hyundai Tucson. This is usually related to the dual-clutch transmission. When the car is new, the clutch plates may not be properly worn in, and unstable oil pressure can cause uneven power delivery. From my experience, this happens more often during frequent low-speed starts and stops, such as when suddenly accelerating in heavy traffic. It could also be due to unoptimized transmission control modules or clogged oil passages affecting fuel supply. I recommend starting with basic checks, like changing the transmission oil or filter. If the problem persists, take it to a dealership to scan for fault codes. Modern cars have complex electronic systems, and small issues can escalate. Jerking not only affects comfort but can also damage transmission components over time. Addressing it early can save on repair costs.
