2013 Cadillac ATS: Hypersensitive Driver Assist

June 7, 2013

2013 Cadillac ATS

Well, you never can be too careful, I guess. While reversing our long-term 2013 Cadillac ATS into a parking space on the street, the car abruptly dropped anchor, grinding to an immediate halt. A loud alert sounded, and the car wouldn't move.

I was momentarily bewildered. What the hell had just happened? I had been alternately using my mirrors, the backup camera and looking over my shoulder while performing this routine parking maneuver. All was normal. Now, I was sitting there in an immobile car with a shrill noise in my ears and a heart rate that had just doubled. In addition to scaring the bejeezus out of me, I found that the ATS had also set its parking brake. All while still in Reverse!

I threw it in Park, went around back and found this single blade of tall grass in the general vicinity of the Cad's proximity sensor. This nefarious obstacle had triggered the Rear Automatic Braking facet of the car's Driver Assist package, natch.

    In Soviet Russia, car drives you...

  • did it allow you to move without an alarm once the grass was moved?

    Your experience with this Caddy has bee very insightful. I have learned that I will NEVER purchase a car with this level of intrusive nannying unless it actually does ALL the driving (and parking) for me.

    Imagine what will happen when driverless cars become widespread and a blade of grass caused the car to come to a screeching halt in the middle of a busy freeway.

    wow. Technology fail. Talk about a dangerous situation where the car has immoblized itself but you may find yourself in a situation where you need to move immediately.

    Sounds like the driver assist package creates a serious safety hazard. If you were on a busy street or parked on the side of the road, Cadillac can't seriously believe taking away the ability to operate the car is a good thing. Imagine having to make a three-point-turn on some back road or pulling out of your driveway. How wonderful would that be trying to get out of the way of someone barreling down the road towards you while the systems are screaming at you and the parking break has set itself.

    In HAL 9000 tones, "You don't want to park there, Dave".

  • I don't think it was a blade of grass that caused it to stop you. I don't think GM's sensors are that precise or sensitive. However you are very close to the curb and if the steering wheel is turned the computer could then calculate that the angle and direction you are backing will cause you to hit the curb. The ATS is not going to have you damaging it's shoes.
