Tesla Model 3 (2020), I had to replace the battery. 16,210 euros, equivalent to 71,150 zł. Luckily, it was under warranty.
Our reader, Mr. Grzegorz, owns a Tesla Model 3 Standard Range Plus, which is the version that—after several upgrades—is now called the Model 3 RWD. The car is already six years old, and one day it stopped charging. Fortunately, the manufacturer agreed to resolve the issue under warranty, though it took some time. The battery tailored to this specific vehicle wasn’t available until more than two months after the malfunction. The total cost of the replacement was 16,210 euros.

Malfunction
Repair
My car is a TM3 SR+ (2020); I got it brand new, picking it up in person at a dealership near Berlin (Germany). According to the specifications, it should have a range of 409 kilometers, but after 100 kilometers driven, the odometer showed 375 kilometers. I believe this is due to the wheel configuration. The rate of battery degradation greatly disappointed me — after six years and 130,000 kilometers driven, the fully charged car still only showed 327 kilometers (87% of the original value, 80% of the specified range).

Failure
On August 22, Tesla displayed the BMS error A079, which prevented the car from charging even to 50 percent battery level (illustration below). The vehicle stopped charging. I reported the issue through the Tesla app. The service team performed a remote diagnosis and identified a fault with the battery pack. Since the car was 200 kilometers away from the nearest service center, a tow truck was sent to retrieve it. I was immediately informed that the battery was unavailable and that I would have to wait for it. Fortunately, I was given a replacement Tesla Model Y Performance with free charging.
Repair
The error was classified as a defect that would be repaired under warranty, as 8 years had not yet passed since purchase and I hadn’t driven 160,000 kilometers. The notification about the battery delivery came on Tuesday, October 27, about two months later. I read online that Tesla often installs refurbished batteries, so I was a bit worried about the quality of the battery pack that would arrive. To my surprise!, a brand new battery was installed for me. It was a newer version, so the wiring and charging port were also replaced.

Right now, my Model 3, fully charged at 100%, shows a range of 385 kilometers, which is more than when it was new — though it’s a small increase of just +2.7 percent. I’m not sure about fast charging since I rarely use Superchargers. I basically only recharge at home.
The whole process cost me nothing, but I received an invoice detailing the work done. If I had to replace the battery myself, it would cost me 13,622 euros net plus VAT, totaling 16,210 euros. At today’s exchange rate, that’s 71,150 Polish zlotys. It wouldn’t be cheap at all… Fortunately, not only did I get a new battery for free as part of the warranty, but I wasn’t restricted either because I had a replacement car.
