The owner of a Porsche Taycan 4S is suing after vehicle importer and seller TTS Eurocars refused to replace its battery after an accident. And it’s sort of confusing.
Jason Ling, a 44-year-old Singapore resident, is suing TTS Eurocars for over $300,000 after they refused to replace an EV battery following an accident. This amount covers the 470 days he was without his Taycan, as well as the cost to repair the battery at another mechanic. TTS Eurocars is fighting back, claiming that there was no breach of contract on its part.
Ling purchased the Porsche Taycan 4S from TTS Eurocars in March 2021 for around $450,000. The signed contract read that the car is covered under the dealer’s warranty against defects for the next five years. The following year, January 2024, Ling took the car to TTS’ workshop when he got a warning message for “electrical system fault.” The inspection found that the 12-volt battery (not the EV battery) was faulty. TTS Eurocars told Ling to get it replaced if the message appeared again.
A month later, the Taycan broke down and had to be towed to TTS Eurocars’ shop. Once again, the 12-volt battery was found faulty — and so was the EV battery. Over 70 days later, Ling had the EV battery replaced under TSS’ warranty. He paid $5,995 to replace the 12-volt battery.
The very next day, Ling’s Taycan was rear-ended while he was stopped at the exit of a parking lot.
The following month, the Porsche was sent to TTS Eurocars for a repair. Ling was supposed to pick up the car in a few weeks, but he was told on the day of pickup that the vehicle was unavailable. The EV battery had been ruled faulty, resulting in the Taycan 4S being kept at the shop for 278 days. During these days, Ling claims he contacted TTS multiple times but never got a real answer. At one point, he had even gone to the shop in person and was given a letter stating that TTS could not claim under third-party insurance. In other words, they couldn’t cover the cost of replacing or repairing the EV battery.
Ling would have to pay for it himself.
In July 2024, months after his vehicle was trapped at the shop, TTS Eurocars told Ling not to tow the vehicle, as it could affect conversations with third-party insurers. The company also asked Ling to pay for the costs of dismantling the EV battery.
The next month, Ling had a lawyer send a letter to TTS Eurocars demanding that the Taycan be fixed under its warranty. He also asked for the $5,995 for replacing the 12-volt battery to be returned. He then towed the Taycan to another workshop in March 2025, getting the repairs completed in July 2025.
The argument has largely become that the Taycan 4S did not meet the promised quality standards, citing the 12-volt battery’s failure after just a few years, a faulty EV battery, and an issue with the coolant pump. In response, TTS Eurocars stated that the Taycan was found to have “satisfactory” quality during the assessment prior to the sale. TTS also added that the battery warranty excludes damage from a collision. Third-party insurance had also rejected the idea of replacing the damaged battery.
Was the Porsche Taycan 4S’ EV battery under any kind of warranty?
Electric vehicles are often more cost-effective to own than combustion-engine vehicles because they require fewer repairs, but one of the biggest expenses is replacing their batteries. An out-of-warranty replacement for the Porsche Taycan 4S’ battery is estimated to be between $25,000 to $45,000. This is nothing to scoff at, even if you’re willing to spend millions on a vehicle (that will never see the light of day). For this reason, your EV battery’s warranty is extremely important.
Every automaker has its own EV battery protection. Porsche offers an 8-year/100,000-mile warranty on Taycan batteries, covering repairs, replacements, and faulty components. Basically, if the battery capacity drops below 70%. Physical damage, including accidents, is not covered by Porsche at all.
TTS Eurocars states that drivers have a 5-year dealer warranty. However, the warranty also excludes damage from accidents. If the warranty explicitly states this — it’s in writing and signed by the buyer — I think Ling will have a pretty tough time winning this case. Ling claims the Taycan he bought had a faulty battery to begin with, but TTS Eurocars already replaced the battery it came with. The new one was just rammed by a Mazda the following day. However, maybe Ling could get some money back for TSS keeping the vehicle at its shop for so long. It’s safe to say that it’s not a cut-and-dry situation.
The lawsuit was transferred to the High Court on January 16th, 2026, two years after it was filed as a Magistrate’s Court case. The next case conference is on April 16th, 2026.
