Warning - Pro-Pilot Assist issues

Fri Aug 03, 2018 12:49 pm

So I was in stop and go traffic and I was following a black Lincoln Navigator. When coming to a complete stop, once I got within 15 feet of the stopped Navigator, the car would accelerate like it couldn't see the Navigator any more. I stopped the first time and I tested it again and it happened a 2nd time.

So warning to everyone using the Pro-Pilot assist feature that if you're following a large, boxy vehicle, be extra careful when it's stop and go because the car might decide to accelerate

The adaptive cruise control is lousy at lower speeds. It decelerates way too quickly, then is reluctant and slow to re-accelerate. Unless, of course, you are behind a large boxy vehicle, apparently.

Also, it seems that e-Pedal gets turned off (even if it says it's on) when you have ProPilot engaged. I was using it in heavy traffic on a very steep hill in downtown Seattle, and after it brought my car to a stop it started rolling backwards! I tapped the brakes and it stopped right away, and after that e-Pedal held the car there just fine.

Wow that's very dangerous. Makes me wonder what the real world usage of ProPilot is. Makes me think that it's a gimmick versus really being able to make you less fatigued while driving.

If anything, it'd increase my heart rate just by not being able to 100% rely on it and not know if one moment it might decide to accelerate towards a black boxy vehicle.

I'm on the market for a 2018 Nissan Leaf and the unreliability of the ProPilot and the battery degradation (in sunny Southern California weather of 100F+) is really discouraging given I've test driven this car and love it...........

If you have legitimate concerns about a safety issue/defect, please file a formal complaint with Nissan corporate and NHTSA via safercar.gov. If you believe a dealer can resolve, take it there first.

For those who haven’t bought or leased yet, you can choose not to pay for feature.

I've learned to use mine as just an enhanced version of regular cruise control - at speed, on the highway or main streets only. I don't use it for stop and go driving because of the too-abrupt braking, too weak acceleration, and now because of the truck blindness issue.

I'm contemplating getting the SL just for the ProPilot... Did a brief test drive with it and found braking to be abrupt and slow acceleration as well. I guess the technology is still in its infancy... Kinda had high hopes for it :/

I have encountered one situation in which the acceleration after braking for traffic is actually too hard: when a car turns at an intersection in front of you, your car will then try to blast through the intersection while accelerating quickly. Nice programming, Nissan!

I have ACC on my Grand Cherokee from 2015 and absolutely love it. I depend on it completely in all situations.

I test drove an 18 Leaf the other day and we took it out on the interstate to play with ProPilot. The ACC part wasn't bad in that situation, but I was amazed at how bad lane keeping was. It tried to veer out of its lane twice while it said it was in control. I had to pull it back both times from the next lane over. Maybe I'd get more comfortable over time but from that brief experience I think it would make me more stressed versus not using it.

The lane keeping isn't terrible on mine, but it has the rude habit of steering just over the white line, then vibrating the wheel to "warn" me about what it just did.
