Taycan Charging Error

My beloved Taycan encountered its first major trouble.

One evening, I came home in the Taycan and plugged in the usual 200V home charger cable as always. However, the next morning when I got in the Taycan, I noticed the charge hadn’t increased at all.

“Huh? Maybe the charging cable wasn’t properly connected?” I thought, but I still drove the Taycan to work as usual that day. When I returned home in the evening, I carefully plugged in the charger again, but the charger showed an error message.

And the Taycan’s charging display also showed an error.

After getting home, I told my husband, who immediately checked both the Taycan and the charger. But no matter how many times we tried, we couldn’t tell if it was “a charger malfunction or a problem with the Taycan itself.” (The charger is Porsche genuine, but it’s an older model I bought on Yahoo Auctions originally for a 970 Panamera Hybrid.)

Still, it felt unsettling to go to bed without knowing the cause, so late that night I decided to drive to a coin parking lot with a public charger.

If the Taycan shows an error, it means the Taycan is faulty; if it charges normally, the charger is faulty.

However, surprisingly, there weren’t many public chargers open late nearby, so I drove about 20 minutes to a coin parking lot with a public charger, parked, and plugged in the cable.

If it charged fine here, it meant the home charger was faulty. If the Taycan showed a charging error again, it meant the Taycan itself was the problem.

Nervously checking the Taycan’s charging status… the error appeared again.

Ah… so it really was a problem on the Taycan’s side…

Having confirmed this, I paid the coin parking fee for just 2-3 minutes (laughs) and went home that day.

Taycan Parts Replacement

The next morning, I contacted the Porsche Center and arranged to have the Taycan inspected that same day.

Fortunately, the battery still had about 50% charge left, so I was able to drive the Taycan to the Porsche Center under its own power.

Upon arrival, the staff said, “It might be fixed by a reset,” and I thought it was probably a minor error that would be resolved that easily. But about 30 minutes later, they informed me, “The reset didn’t fix it, and it will take more time to identify the cause.”

Since I had my laptop with me, I worked while waiting, and after an hour…

The service staff told me, “There is an error in the Taycan’s internal computer, and the entire part needs to be replaced.”

Wow!!!

The Taycan’s 800V system voltage requires precise electronic control over voltage, temperature, and many other factors to prevent malfunctions and runaway. To a layperson, EVs might seem simple in structure, but in reality, they are extremely complex systems, they explained.

The exact cause couldn’t be identified, but some error occurred that caused the computer itself to fail to start.

I asked, “Could it have been caused by how I was charging it…?” but they said, “We don’t think that’s the case,” which was a relief (laughs).

However, this part has to be ordered from Germany (a common Porsche story), and it will take about two weeks to arrive, plus about a week for the replacement work—a total repair period of about three weeks.

Since I had to pick up my child from kindergarten that day, I borrowed a loaner car and went home. Just yesterday, I finally received news from the Porsche Center that the parts order was confirmed.

The repair period is expected to be longer than initially thought: about three weeks until the parts arrive, and nearly a month including the work.

That’s quite a long stay in the shop… but well, it can’t be helped.

Also, since this was within the warranty period, the parts replacement was covered free of charge. Additionally, several recall repairs will be done at the same time.

Warranty Is Important.

This experience made me realize once again how important warranty coverage is. When you make such a big purchase, the peace of mind that you’ll be properly protected if something happens is priceless.

I hadn’t heard many stories of major Taycan troubles around me, but it turns out unexpected incidents like this do happen sometimes. Since these cars pack the latest technology, their structure naturally becomes complex, and errors are bound to occur.

Well, I’ll take it easy and think, “These things happen sometimes,” and continue to patiently enjoy my time with my beloved car.
