PORSCHE Complaints

Received a recall notice from Porsche yesterday regarding a potential wiring problem with the climate control coolant pump that, under certain humid conditions, could result in an electrical short and engine fire. In the notice, they recommend “out of an abundance of caution” to “park the vehicle outside and away from other vehicles or structures”. Sounds serious. Called my Porsche dealer in Atlanta to schedule an appointment ASAP to get the problem repaired. The repair parts are unavailable and they don’t know when they will be shipped. Was told that it could be a month or more before they know. My complaint is not the defect (which Porsche identified); but, the manner in which this is being handled. Parts for a defect that sounds this serious should be available before sending ominous-sounding recall notices to customers.

The contact owns a 2020 Porsche Panamera. The contact stated that while driving approximately 35 MPH, the vehicle started losing motive power, jerked, and the vehicle would not properly accelerate. The vehicle was later taken to the local dealer who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 50,000.

The PCM infotainment unit continuously reboot itself. It drains the battery very fast.

After 9 days the car showing 12V battery low, it completely was completely dead on March 01, 2023 despite my all efforts to drive around (more than 400 miles) and charging. Reported the issue to Porsche helpline and they arranged the vehicle pickup from my home same day and the car was serviced at Paul Miller Porsche dealership in Parsippany, NJ. They charged the 12V battery, updated the software and returned after 3 days. The big battery had around 35% charge when it happened. Luckily it happened at home but I’m nervous about taking it out and get stranded somewhere.

No heater for cabin or front windshield defroster, available for inspection. Ice build up in inside limiting visibility Taking care in but need to wait 4 weeks for appointment. Has not been inspected yet. No warnings just cold air blowing.

A terrible drain design that has plugged drains emptying rain water into the car. The water from rear drain will fill into then Battery & Sub woofer compartment under under the spare. The drains are not easy to access for cleaning either. you have to be pulling off wheel liners and yanking/cleaning the plugs just so my car doesn’t flood itself. Porsche should modify the plugs so water does not flood into the car. This water damaged caused over $6,500 worth of damage. The main factor is the Airbag Sensors were faulted by the water damage. Might have effects the Airbag function if I was in an accident. That is what scares me

Foam insulation blows out of windshield defroster vents. It is much worse when heat and fan are turned on. The windshield does not properly defrost and passengers are deluged with particulates and large chunks of black foam. This is a hazard to both breathing and visibility. Porsche is aware of the problem. Dealer says owners view as too expensive to fix. A recent Porsche Club of America newsletter article discusses the problem as a hazard and a paid advertisement pushes an alternative repair.

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.

The brakes fail in wet conditions. Porsche Taycan has 2 brake systems- light braking is regenerative braking (converting mechanical energy into electricity) and for heavier braking the mechanical disc brakes take over IN THIS FAILURE SITUATION in wet conditions pressing the brake pedal does VERY LITTLE to slow the car. DURING THESE FAILURE SITUATIONS, there is 0 regenerative braking occurring. Normally if there is 0 regen braking mechanical brakes engage at 1% brake pedal press so the entirety of the brake pedal engages the mechanical brakes. DURING THIS FAILURE SITUATION, the mechanical braking system does not engage early so it does not begin to engage until near the end of the brake pedal travel. DURING THIS FAILURE EVENT, THE MECHANICAL BRAKES ARE ONLY AT MINIMAL STOPPING POWER (+/- 20%). It has been compared to the first stop after getting a car washed– one must ‘jam on’ their brakes in order to get their car to stop, after which it tends to stop well. Cars come from the car wash at 1-3 mph, so 10-20% braking power does not put the user in jeopardy. IN THESE FAILURE SITUATIONS THE PORSCHE TAYCAN only has 10-20% stopping power WHILE TRAVELLING ‘AT SPEED’ ON NORMAL ROADWAYS The first time this happened I was approaching a stop light in traffic. If the turn lane weren’t empty I WOULD HAVE CRASHED into the cars ahead of me; I jerked the car into the turn lane & eventually came to a stop, with the brake pedal pressed in at 100% for the entire time. It happens at speeds from 3-50 mph It HAS been reproduced with myself in the car by Porsche service, and by other people in their cars, it was reproduced on my car AND ALL OTHER TAYCANS ON THE LOT at the dealer – each car did it The dealer has done ‘everything in their power’ but it is still happening. I was told Porsche NA was investigating on their wet track at their Atlanta HQ, but that the cars ‘tested as designed’ No warning messages or errors –the regen braking gauge always shows 0% while this happens

Porsche and VW has a drainage issues with certain model vehicles. The drainage plug is set in the trunk near the battery, main system cpu and amplifier. Water gets drain into the lower compartment of the trunk and causes electrical issues with the vehicle. It's been a design flaw from porsche since before the Cayenne was created. To repair the damage it cost upwards of $3,000 per damage battery, electrical components, amplifier are all billed separate. Porsche warranty refuses to honor the design flaws in correct the issues. Owners are not made aware of the issue until it becomes an issue then porsche wants no part to do with it. The drainage location can cause an electrical fire and engine malfunction while driving.
