On my 2024 Macan GTS is there any way to turn adaptive cruise control off and have just normal cruise control ? I have almost been rear ended three times because of this stupid option

 

No.

 

The most simple answer is no. However if i recall correctly there is a toggle on the computer system that can only be accessed via PIWIS to disable adaptive cruise control

 

Let's go to your settings that you were using when you developed the rear ending problems. What were they? For instance, did you have the maximum speed set at something really high and this was a low speed zone? Tell us more. I am in love with my adjustable program, but I play it like a finely tuned instrument. Maybe when we can see what you are doing, we can make some adjustment recommendations for when it is in use.

 

First, I never speed in over 65 years of driving nor do I tailgate. If I wanna go fast, I go to the track. I have set the sensitivity of the adaptive, cruise control at its minimum. and it has activated the brakes at various speeds. He will also activate sometimes on a 2 Lane Rd. with oncoming traffic if it happens to be in a bend in the road. bottom line in my mind it’s a worthless nanny, but we have so many computer generated “aides to save you from lack of attention to driving” on modern cars. It’s ridiculous

 

are you using lane change assist in combination with the adaptive cruise?

turn the LCA off.
I’ve done that and have had zero issues in every aspect of using the adaptive cruise.

 

I’ll try it . Honestly the most fun car to drive , and I’m a young 82, in my restored and modified 911 SC the only computer assistance is the person in the drivers seat . That does not say I don’t enjoy the Macan GTS or the diesel Cayenne but they are to get me there . The SC is to enjoy getting there

 

Any possibility that people tend to tailgate? And that it has nothing to do with the Macan?

In other words there is nothing you can do about it.

 

Are you saying that you have the following distance set to the minimum following distance setting? If that is the case, the minimum following distance setting can cause the automatic braking to be fairly hard resulting in following drivers to also have to brake hard.

I don't have a Macan but I've had a number of Macan loaners when my 2022 Cayenne has been in for service and repairs. I don't remember the adaptive cruise control on the Macans working any differently than on my Cayenne.

On my Cayenne, I normally use the second longest following distance except when I'm in heavy highway traffic when I select the longest (i.e. most sensitive) of the five following distance. This is especially important in traffic that repeatedly and erratically speeds up and slows way down including to a full stop. Selecting a long following distance causes the automatic braking to be gradual and gives following drivers time to also slow down gradually..

It's been the same on all the other vehicles with adaptive cruise control that we've owned. All the non-Porsche vehicles we've owned have had only three following distance choices and I've always selected the longest of the three for safety to keep from being rear ended or just pissing off other drivers.

An exception is when approaching a vehicle from behind that I expect to pass such as on a 2-lane road or a 4-lane divided highway. In those cases, I continually adjust the following distance as I approach and pass. Of course on a 2-lane road, I'll likely punch the gas pedal to pass quickly.

I've had automatic braking happen on the Cayenne when encountering oncoming vehicles very rarely - maybe a couple of times in 21,000 miles / 2 years. I had this happen much more often in non-Porsche vehicles. I always keep both hands on the steering wheel ready to cancel the cruise control if it misbehaves. I'm also poised to click on the 4-way flashers if it looks like a following vehicle is closing in on me too quickly and might hit me. Activating the emergency flashers when/after coming to a stop has saved me from being rear ended a number of times.

Adaptive cruise control is only a driver assistance feature - it's not automated driving. One still has to pay as much attention as when not using it.

 

Is the radar sensor in the front clean? I'm surprised to hear about the OP's experience. I have used Adaptive Cruise + LCA quite a bit on longer highway drives and have never had an issue like this. It honestly works quite well. The LCA is way more mild than most vehicles (it will not actually keep you centered in the lane like some will), but the adaptive cruise in stop and go works great and has never made me feel like I was going to hit something. 2020 Turbo here. I would consider taking it in and having the dealer have a look at it. Sounds like a malfunction of one or more of the sensors honestly.

 

Did you mean "LKA" instead of "LCA"? LCA is what some other car makers call blind spot monitoring and only warns of vehicles in your blind spot. "LKA" is Lane Keep Assist and is what pulls (jerks?) you back into your lane if you contact lane divider lines. Porsche calls the feature that keeps you centered in the lane "Active Lane Keep Assist" or ALK. ALK is not available on the Macan but comes with the optional InnoDrive on the 911, Taycan and Cayenne.

 

I told my sales guy LKA still in development and doesn't work well. Did not want to be a beta tester.

I set the adaptive to closest following and only once had it slam on the brakes.
Never been rear ended.
