4 Electrical System problem of the 2012 Porsche 911

Failure Date: 10/18/2023

1. Door panel issue. I have a 2012 911, and have noticed last year that the door panels have popped up on both sides, it looks like the glue has given way. It seems that this is a common issue for Porsche 911. 2. Keyless entry issue. I was not able to lock my car by pressing by the door handle's button. I was able to unlock the car. I then tried on the passenger's side and was able to lock it. It's been going on for months, and every time it occurs I will have to spend minutes to get into the car.

6 Electrical System problem of the 2022 Porsche 911

Failure Date: 04/16/2023

I have a nearly brand new 2022 Porsche 911 gts with around 3000 miles on it. Around 3am on 4/16/23, I was driving on highway and experienced serious engine failure. Put me and other drivers driving on the highway in a life threatening situation. I or anyone who is driving could be killed while my car stopped on highway and later on a local road. It gave me insomia, paranoidism, trauma etc. In details, when the engine first failed, the speed was decreasing, I stepped on gas but there is no response from the car, the speed still decelerated until I made my way to the shoulder of highway. It finally completely stopped, I failed to start engine for few time and in the mean time the car had burning smell. I waited for 5-10 mins, then tried to restart the engine, car was started but it felt very weak and was really hard to control and steer. I stepped on gas but it's not accelerating. The engine kept failing and lights went out, I can’s see the road clearly and can't really steer the car. For my own and other people's safety I had to drive the car to the exsit! the car bumped into sidewalk curb, after multiple times of restarting the car until I made to the nearest highway exist. Whenever I stopped the car, the engine would turn off, then at last, I reached to a signal light and that's when the car had completely stopped and I can’t start the engine after trying for many times. Around 3:30am I called Porsche road assistance, they said they would tow the car in 60-90 mins. After 60 mins I called the road assistance again to follow up they said can’t find towing company and asked me to call my insurance instead. At that time it's almost 5am I was very frustrated, exhausted and cold didn’t know what to do. I had to have my friend picked me up and left the car on the road. Police officer had the car towed and I sent the car to riverside dealership. Called Porsche and filed claim requested for buy back last week, no update as of now, need your help on this. Thank you!.

My air conditioner/heater fan does not come on after car has been sitting for a few days in a humid climate. This problem is documented with a temporary fix on the static. Nhsta. Gov site. Https://static. Nhtsa. Gov/odi/tsbs/2021/mc-10186302-0001. Pdf the problem is it happens to me every week or so. There is no permanent fix. This is a safety issue because without the fan motor the defroster doesn't work and the windows can fog up creating a dangerous situation.

8 Electrical System problem of the 2015 Porsche 911

Failure Date: 04/14/2020

In may 2019 I purchased a certified pre-owned 2015 Porsche carrera gts and had it for 11 months before it caught on fire while driving it. A forensic investigation revealed that the cause of the fire was the electrical board located on the inside of the cabin near the right rear tire. On the day of the incident, after driving the car less than 15 miles from my home to a nearby property I noticed the car was smoking as I pulled into the driveway. I parked the vehicle and found that there was a small fire in the engine compartment. I couldn't get to the car in time with a fire extinguisher and by the time the fire department arrived, the car was engulfed in flames. I'm now faced with a total loss for the vehicle and not to mention reluctance to ever purchase another Porsche in my life. I've dreamt about owning this Porsche carrera (gts) since I was a child and this experience has totally altered my perception. If my family had been in the car with me, this could have turned out disastrous and for that my confidence has been shattered with Porsche. I am also left searching for a car that is close to as nice as the car I had (fully spec'd and decked out carrera gts) which I've had no luck doing within the price point I can afford given the insurance pay out.

9 Electrical System problem of the 2015 Porsche 911

Failure Date: 01/19/2017

Car heating system cut out. I was driving on a highway at below freezing temperatures and the heater system died. Not having heat, the windshield fogged up immediately and cold rain started freezing on the windshield requiring me continously clear it with washer fluid until the car ran out of washer fluid and I had to stop. After doing some internet reasearch it seems like this is a problem affecting many Porsches of this type. It seems like Porsche is using a failure prone valve unit in 6-8 places in the car (depending on model type). The problem seems to be well known and my dealer knew already that its a valve problem when I mentioned it and conceded that it is an issue. Nevertheless, it looks like Porsche decided not to recall the valves, but simply replace them when they fail. This might be ok for drivers in warm weather, but in cold weather this can mean an immediate stop or risking an accident due to low visibility. In addition, the same valve is apperently used in other systems of the car and can cause failures there as well.

10 Electrical System problem of the 2003 Porsche 911

Failure Date: 01/14/2011

I was driving my car to a charity event hosted by a high school tennis team when I noticed steam coming from my engine bay. All my cars coolant leaked out into the parking lot and it created a very large puddle. My wheels were covered in coolant and it created an unsafe driving condition for the participants behind me who were follow me into the car was. As all of the coolant evacuated my car, it is a miracle that it did not happen on the freeway where it could have caused an accident. Because the cause of this was faulty coolant lines, my alternater was also shorted and need to be replaced, again, if this happend on a long trip or on the freeway I could have been stranded.
