Vehicle randomly thinks that I’m about to be in a collision when nothing is in front of me. This causes the vehicle to just stop and almost causes me to have an accident.

I was notified of APB6 recall and received a mailing suggesting I don't use the charger and that I should buy an aftermarket charger and would be reimbursed. It has been over 3 months and I have contacted Porsche multiple times and they have created trouble tickets that have just expired. I have yet to be reimbursed.

It was stop and go traffic. I was distracted and the car failed to auto stop and I hit the car in front of me. The alert did come on after the collision. I would assume the automatic braking failed or the collision would not have occurred. It was a low speed impact so not a major safety risk but even a minor collision can have a significant injury in susceptible subjects? The problem has not been reproduced to my knowledge. The component has not been inspected. The car has been evaluated by a body shop for damages and the damages are significant. The warning light came on in an inadequate time to prevent the collision. There were no other warning lamps

I discharged the battery to 7% then recharged to 100% using my home charger. When I got into the car, I had an error message stating: 'electrical system error park vehicle in a safe place'. The message disappeared later that day and I was able to drive the car to the dealer.

On three separate occasions over the past year, my car's emergency collision avoidance system was triggered, (an alarm sounded, a red symbol was on my dash, and the brakes locked), erroneously. No accident occurred, but in the second case below, it caused the car behind me to lock up their brakes and just avoid hitting me...thankfully they were very alert. The first two occasions happened two months apart, but at the same time of day and at the same location. On both occasions, I had driven down a street at approximately 7:30 in the morning. I slowed to make a left turn and then came to a complete stop because traffic was coming in the opposite direction. There was also a car facing me in the alternate lane of the road that I was turning into. Once all oncoming traffic had passed, I pressed the accelerator to make a left turn and turned and moved forward just a few feet when the emergency collision avoidance system was triggered and the car's brakes locked. Within a few moments, the system released and I was able to drive on. Both situations were identical in location and the traffic situation was as I just noted in both cases. The most recent occasion that the system was triggered happened this week. I was in a right turn lane with a car in front of me and one or several cars behind me. I had come to a stop behind the car in front of me who was waiting to make a right turn onto the road. Our turn signal was red. Once the turn signal turned green, the car in front of me moved forward and made the right turn. I accelerated and went about 25 feet and was about to join the road when the collision avoidance system activated, (an alarm sounded, a red symbol was on my dash, and the brakes locked). The car behind me skidded to a stop, luckily without hitting me, and then my car's system released and allowed me to drive on. This must be happening to other users. If so, Porsche should be made aware and they should fix this.

There is obviously a design flaw in the fan cooling system for the main high voltage 93.4 kw battery. The cooling vents allow small gravel to enter the intake ports powered by fans to cool the battery. (this is a major issue for areas of the country where gravel is used for winter road maintenance. This issues arises every snow season) Gravel gets into the ports and can possibly jamb the fan propeller blades thus not being able to cool the battery properly. I have a work order at the dealership to clean out the cooling ducts. when the gravel enters these ducts they make a grinding sound when the fans engage. The dealership reported this to the manufacturer, and the response from the manufacturer was it is not their issue. The service dealership said additional screening over the intake ports can not be done because information from the manufacturer states this would impede the necessary airflow to cool the batteries. To further bring attention to this design issue, the high voltage 93.4 kw battery failed, July 19, 2023 at 17,551 miles.

Porsche Taycan has been plagued with recurrent electrical issues despite 2 factory recall messages and reported fixes. The car screen and gauges all blacked out while driving despite reportedly fixing this electrical problem. Further a serious brake issue occurred (pedal going all the way down making harsh sound) within 2 years. If that’s not enough the car had an “serious electrical system” error message with yellow battery “requires service” and been in the shop for 4months and they apparently cannot fix it. These are all major safety issues for a brand new car within the first 2 years of purchase.

The car was suddenly stalled at road multiple times, showing red warning "Engine control error. Park vehicle in a safe place" . Porsche is unable to solve such major safety issue of its electric car for past two years.

I was driving 30 mph in drive mode on westheimer rd when the car suddenly emergency braked and lost all power i went from 30 to 0 in about a second. Yes the car is available for inspection on request. The car had 180 miles of battery power. The car behind me slammed their brakes on and nearly slammed into the rear of the car. The red warning light came on "Electrical System Error park vehicle in a safe place". There was absolutely no warning before this occurred. I am afraid for my life with this car i nearly got into an accident at 30 mph let alone if i was on the highway i could have easily died. This problem has been reported with thousands of porsche taycans. The car has been at the porsche dealership for a week so far where they are reporting electrical faults in the car.

On March 30, 2023 I had my winter tires and wheels changed out for my summer tires and wheels Goodyear Eagle F1 Asymmetric 3 in sizes 265/35ZR21 101Y XLand 305/30ZR21 104Y XL. At the time, I had about 25,000 miles on the car, and perhaps 15,000 miles on the summer tires. The tire inspection report from Porsche indicated that I had acceptable tread depth on all tires, and no unusual treadwear. Around the end of June I started seeing a very slow pressure decrease in my left rear tire, from about 41psi to 38 psi over a few weeks. On July 18, I experienced a severe drop in pressure to 22 psi and I filled the tire with air to 45psi and used the tire sealant to drive the car to the Porsche dealer, and arrived with 29psi. At no point during the time I had the summer tires on did I ever do anything unusual, or hit any road hazards. Porsche provided me the attached video showing severe cracking between the sidewall and tread around the entire diameter of the drivers side rear, and cracking around part of the diameter of the passenger rear. They claimed this was due to 'misalignment' of the rear tires. The alignment report (attached) shows the drivers rear was within specification, and the passenger rear was 0.2 degrees out of camber (-1.8 deg vs spec of -1.6 deg). There was still 4mm of tread on the tire, and no unusual tread wear was noted on any tires. I have replaced all 4 tires, and am very concerned that the same thing may happen, and I could have a catastrophic failure at high speed. Porsche is unwilling to do anything other than pay for the drivers tire. I don't see how I can be assured that the exact same thing won't happen in the future, since there was no testing or observation that Porsche did that indicated any kind of problem.

I was driving in the fast/lane of the freeway, and suddenly the car flashed red "Electrical System Error" "Park Vehicle in Safe Place". The car immediately started to decellerate on its own and I didn't have time to go over to the right so had to move into the left shoulder of the freeway. I was stuck in the middle of the freeway, with cars driving fast coming around a bend of the freeway behind me having to swerve out of the way. Cops finally came to give me cover from behind. Dealership still trying to figure out what the issue is.

In the center of the lane on a straight highway, vehicle will suddenly brake without warning. There are no vehicles ahead. A warning light comes on the dash and says “Driver Control Required,” yet both my hands are on the steering wheel. The feeling is that of a brake check performed by the electronic sensors of the car, and not at the driver’s command. Had there been a car following behind me, he could have hit me in the rear. Dealer is aware of the complaint but says, “system is working as designed.” Manufacturer responds by directing me back to the dealership. Yet the problem persists.

After the most recent recalls were repaired (all software) on my vehicle the brakes in the car were terrible. Soft /dead pedal feel. I almost rear ended other cars multiple times wen braking at slow speeds. Occasionally the pedal would go all the way to the floor when slowing to 3-5mph - This was consistent over multiple days after I got the car back from recall updates. Also , the first inc of brake pedal travel did not slow teh car at all.

Suddenly my vehicle showed "electrical system error", then it can't move, no matter forward or reverse, luckily it was parked in my garage, I can't image if it was on highway when your vehicle suddenly lost power. I don't remember how many times my Taycan was recalled in past 1 year, but it looks Porsche still haven't figure it out, maybe it's still a prototype.
