Toyota huge battery degradation – Taboo topic

By Strom Trooper

Toyota Auris Hybrid – A Case of Battery Degradation at 246,000 km Battery degradation is expected in high-mileage hybrid vehicles, but this case stands out—not in a Tesla or even a Nissan Leaf, but in a Toyota Auris Hybrid. At 246,000 km, this battery exhibited 82% degradation, with more than half of the battery system…

BMW Hybrid repeated battery failure

By Strom Trooper

Again, the “worst of both worlds” applies to the 2018 BMW G30 eDrive Hybrid, whose complete battery pack is so worn out that repair isn’t feasible without replacing all modules. This vehicle has only covered 150,000 km and first error popped up at 104,000 km that battery is in defect immediately after warranty end, yet…

Nissan e-Power – Expensive placebo

By Strom Trooper

This vehicle serves as yet another example of why some hybrid systems struggle to offer a sustainable long-term solution. After monitoring internal reports and Nissan owner groups, we have observed that the so-called “self-charging hybrid” frequently experiences failures. One particular case involved an electric generator motor failure at just 10,000 km—and this is not an…

Which battery is the best!?

By Strom Trooper

A question even the industry cannot definitively answer, and the answer lies at the end of its life cycle. Without sampling failures, creating solutions for a large number of battery systems, and reaching the final destination, i.e., recycling, it is very difficult to determine which is the best. However, we have summarized the answer into…

Porsche Panamera Plug-In Hybrid 970 – 9kWh for 17000€

By Strom Trooper

During the initial detailed diagnosis of the malfunction, it appeared to be just one problem, but eventually, it was discovered that there were two additional problems with the rest of the vehicle. Purchasing a used hybrid is a very risky move, both for buyers and sellers, as sellers have been recently hanging up in tears,…

E Class W205 Hybrid – Unsustainable defects

By Strom Trooper

Unsustainable defects that once again proves hybrids are the worst of both worlds. A small 6kWh battery with single cell amperages during use drastically higher than on EVs, such that even a good choice of thermal cooling (water cooling in this case) doesn’t help in the long run if the system is underdesigned. Owner reviews…
