Car stalls to a stop

Thanks Kase for the prompt reply. However, it looks like I didn’t make myself clear in the original post so here I attached a video. As I am driving I lift my foot off the gas pedal when at 150 km/h and allow the car to coast freely gear shift is still on drive. I don’t apply gas or brakes the car starts slowing down so much feels like something is dragging it back feels so heavy and I notice the engine noise in the background as the car downshifts, eventually it’ll come to complete stop and if I press the gas again it’ll just accelerate. I have driven a lot of cars and they didn’t behave like this that’s why I feel something is wrong not to mention the erratic acceleration or the not so smooth gear shifting.

Thanks Kase, it’s great that now we are on the same page. There’s a development in my case, before I go to the dealer I decided to make OBD scan for the car and I got faults in the ABS system as shown in the photos. The technician who scanned the car told me it’s something minor probably programming error. He engaged and disengaged the “diff lock” system multiple times after that I drive the car and it feels very normal but I’m still confused to why there were faults in the ABS system showing in the OBD scan and no indication or warning lights on the car dashboard and what guaranteed it won’t happen again without indications. Anyway I’ll take the car to the dealer knowing for sure that there’s or at least there was something wrong with it.

I took the car to the dealer and they did all the tests as per their books, did two test drives with different mechanics and concluded that the car is completely fine that’s nothing is wrong with it. I requested to drive a similar car they agreed and for me the other car felt completely different but their mechanics insisted that both cars felt the same. My car feels heavy feels weighed down feels like something is dragging it back preventing from unleashing it’s potential even the steering wheel feels a little bit rough especially when turning and I am not going to change my opinion even if the whole world tells me otherwise. I guess there’s not much I can do right now I’ll just wait for that random light on the dashboard to pop out and I know it will. Anyway thanks for your help Kase.

Hello Kase, I hope you are still there. I spent the last month chasing the dealer and going around to many workshops to try and pinpoint the origin of my vehicle’s problem and I think I found something. So the heaviness that I feel in the car the weaker acceleration and the noticeable stiffness in steering wheel occurs when I turn on the A/C and set it on low temperatures like 18 degrees Celsius. If I switch off the A/C or set it on higher temperatures the car will perform and feel just perfect, unfortunately I live in a place where the temperature nowadays can reach 50 degrees Celsius during the day and I don’t have the luxury of switching off the A/C or setting it to higher temperatures. So can you please tell me what’s your diagnosis here, is it the A/C compressor that’s messing up with my engine and steering? Please I need your opinion as I guess I’m so close to clarifying this issue and take it to the dealer to solve it. Thanks
