This is a brand new vehicle we call it here in the Middle East Nissan Patrol. If I am driving on a straight flat road and lift my foot off the gas the car will slow down drastically to a stand still even though the gear is always on “Drive”. I have also noticed some delayed speeding up when pressing the gas similar to a gear slippage but not sure. I want to know if this is normal behavior before I escalate the issue to the dealer. Thanks

This is in no way normal. This sounds like a possible torque converter issue or even an engine issue that is related to the intake system.

Here is a guide that talks about stalling while driving:

https://www.2carpros.com/articles/engine-stalls

However, no matter what I would consult a dealer quickly because if more damage is done from you not going to a dealer they may find you responsible. Basically saying that you continued to drive the vehicle even though you knew there was an issue.

Please let us know what questions you have and what the dealer says. Thanks

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.

That absolutely helps and I am going to totally reverse my opinion and say that this is normal. More modern vehicles have a bit more engine braking so depending on what you are comparing it to then it will feel like it is dragging.

However, the fact that it took close to a half mile to slow down to a near stop before you accelerated again then that is definitely normal.

If you are still concerned about it, you could just stop by the dealer and ask that you can drive another vehicle just like yours because you want to just be sure that one feels the same.

Thanks for the video. That really put us on the same page.

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.

More than likely they disconnected something when they were inspecting it for the delivery to you when you bought it. Most of them look like they are no longer active or current so that means the issue is not current. This is why the lights would not be on. Those codes can stay in there for months as they are informational for the mechanic to look at when you bring it in. In other words, they want to keep the codes in there so that if the issue is not happening by the time you get to the dealer, the mechanic can still try and figure it out based on the codes that are in there.

However, I agree with you that this needs to go to the dealer and have them check it out. Please keep us updated with what they find.

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.

The only other option, which I would recommend is consulting another dealer for a second opinion. If the second dealer finds something wrong then that is great. If not then I would call the OEM and at least voice the complaint. They may not do anything but at least it is recorded.

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

Short answer is yes. It can cause this as it slows the belt down which slows the power steering pump and this will decrease the power assist.

However we need to get a new post started for this issue as it doesn't match the header on this post and others will not find it if they have something similar.

Thanks for coming back and once we get the new question posted, we will get on helping confirm this. Thanks
