KIA OPITMA 2016 US SPECS HARD JERK WHEN BRAKING

[muhammadaasif4]

I have a kia optima 2016 US Specs. Sometimes when I start the car overnight for going to work or after work going to home it gives hard jerk before coming to complete stop (it happens rarely inly). This problem is immediately solved if I switch off my car for few minutes and then restart it or even if I keep driving it and I feel when it gets warm or runs few kilometers on road without a need to apply brake. This problems occur only sometimes and I don't get any error on dashboard warning lights when this problem appears. I am looking for the root cause analysis or some good mechanic who handles KIA in Abudhabi and doesnt rips off the property for diagnosis and repairs.
Thanks

Have you taken it to a dealer that can diagnose with a laptop? It sounds to me like a transmission issue, like it's jumping out of gear. When was the last time your transmission oil was replaced ?
