2021 Porsche Taycan driver assistance problems

Filed Sep 17, 2026 · Driver assistance · TX

I was making a left hand turn into a shopping center today around 4:55pm and the collision indicator flashed on and jerked my car to a stop in the middle of the road. There were no cars in my immediate area so it should not have been triggered. It was incredibly dangerous as it left me in the middle of the road, mid-turn. I am unaware if this has been checked by my dealership but we have had other issues that they have claimed to check to no avail.

The car experiences issue, after issue, including but not limited to collision alert warning not functioning, lane change assist failure, and the alarm sounding (disturbing the peace). As Porsche fixes the issues one by one, other matters emerge. The latest is the antania, and communications.

Driving at night at ~72 mph on a 65 mph divided highway with no traffic nearby the Collision Warning message appeared on the dash and the car noticeably slowed perhaps 5-10 mph. Then the msg cleared itself and the trip was completed otherwise uneventfully.

The Taycan offers what Porsche calls Porsche Innodrive (PID). PID once activated, the car uses navigation information and road signs to automatically adjust the vehicle's speed to the speed limit of the road. In some instances, the system speed freezes at, e.g., 50 mph and no longer adjusts to the speed limit of the road. When this happens, the vehicle will accelerate to the speed it froze at. I have experienced this multiple times. See attached image. The car indicates that it would accelerate to 50 mph in a 25 mph zone. This has happened multiple times, with speeds frozen at 65 mph.

The Park Assist system frequently throws a warning that the system is malfunctioning & requires service. During this time the system does not in fact work. However, the system will work again after the car has been turned off for a while, so it seems like the error message is wrong and it’s more of a software problem then a hardware problem that requires service.

Rearview camera picture quality is poor, even in ideal weather conditions.

On August 28, 2021, I was on I-75 in light traffic going about 70 MPH when a red alert on my screen appeared that said, “COLLISION WARNING.” It remained illuminated for about 3 seconds, then disappeared. It startled me because I didn’t know what evasive action to take. There were no vehicles even close to me. I also continue to receive "Driver Attention Required" warnings from time to time. My dealer told me that can happen if I don't have both hands on the wheel. In all instances, I had both hands tightly on the wheel. I sent an email to my dealer's manager with a request that he document this with Porsche corporate and that I receive a written response that includes the number of owners reporting a similar event to Porsche, Porsche's attempts to ascertain a cause, Porsche’s determination of the probable cause and Porche’s proposed remedy. He replied, "I’ve escalated your concerns to PCNA." They asked me to take my 2021 Taycan RWD in for them to download the event log for analysis. I did that. Hearing nothing back three weeks later, I followed up with another email to my dealer. I promptly received a phone call from the service manager saying that he was told by PCNA "that they reviewed the log, they have never seen or heard of the problem and that they don't know what may have caused it."

The rear camera required by the DOT presents a distorted image making objects appear farther away than they actually are. The problem is a commonly discussed topic as an issue with the camera software on multiple Taycan Forums. See: https://www.taycanforum.com/forum/threads/backup-camera-quality-to-improve.6423/page-3#post-91894 The safety of persons standing to close to the vehicle may be impacted as the driver would think they are father away from the vehicle. Damage to property can occur by relying on the image and hitting an object that appears farther away than it is. I backed up into a garage pillar support which presented being farther away from the vehicle than it was causing US$2,500 to repair. The vehicle has not been inspected, this is a widely complained about issue among Taycan owners See the Taycan Forum https://www.taycanforum.com/forum/threads/backup-camera-quality-to-improve.6423/page-3#post-91894

I am getting a warning and sometimes unwanted braking. the warning is that driver must assume control but this happens when I have all the driver's assist features turned off. on a recent 1500 mile road trip this fault happened at least 10 times at highway speeds.

I continuously get 2 messages when I start the car: "Rear Cross Traffic Alert Not Available" and "ParkAssist not available". The biggest problem is that when this happens, the rear camera does not work while in reverse. This has caused several near accidents for me. I took it back to the dealer twice, and they could not find out what the issue is, although they did experience it. I also have photographs of the messages.
