I own a Kia Sonet iMT (Dec-2020 model) and recently started experiencing noticeable juddering while driving in 1st gear. The service centre advised me to apply more accelerator input, saying this behaviour is common in iMT vehicles. I want to understand whether this issue is genuinely common in iMT gearboxes or if it indicates an underlying problem. Since my extended warranty expires on 15 Dec 2025, I would also like to know if any specific components related to this issue should be checked or replaced under warranty. Please advise.

There can be a small amount of low-rpm shudder in first gear if you are crawling in traffic at very low speeds. But if it is constant and happens even at higher revs, then there is a problem.

There are known cases of the Kia Sonet iMT having a judder in first gear. So the dealer cannot call this normal. These juddering points to a problem with the iMT mechanism. Typically, the clutch or an actuator. It should be solved, especially since your warranty is about to expire.

Make it clear to the dealer that the issue is not because of your driving style, but it’s a genuine problem. Request a written report on your problem and ask them to flag it off with Kia. Get the complaint logged before December 15th to protect your warranty claim.

If the dealer does not cooperate, try another dealer. You can also write to [email protected], and we will then escalate the issue to the company.
