Porsche EV owner, 44, sues S'pore car dealer for S$300,000 after not replacing battery following accident

A Porsche Taycan 4S owner who was rear-ended in an accident just a day after replacing his car's faulty electric vehicle (EV) battery has sued the car dealer for more than S$300,000.

According to The Straits Times (ST), Jason Ling alleged that TTS Eurocars was in breach of contract for not replacing the EV battery after the accident.

The 44-year-old claimed that the battery was under a warranty.

TTS denied the alleged breach, saying the battery issue was caused by the rear-end collision and the battery's warranty excludes coverage for damage arising from accidents.

The driver of the Mazda CX-5, which rear-ended the Porsche, has also been sued.

Sought losses of S$300,000

Ling is seeking damages of S$300,000, reported ST.

The sum includes 470 days of his car's loss of use, calculated to be S$112,000, and the cost of repairing his car at another workshop, totalling more than S$105,000.

TTS said the third-party insurers of the driver who rear-ended the Porsche rejected the replacement claim for the damaged EV battery.

TTS said the car was independently assessed, and the battery was found to have been damaged due to the accident.

TTS counterclaimed against Ling's repair costs and six-month storage costs.

Replaced battery & rear-ended a day later

On Feb 18, 2024, the car broke down, and checks at TTS' workshop found the 12-volt battery was weak or faulty and that one of the cells of the car’s EV battery was also weak.

On Apr. 29, 2024, the EV battery was replaced under the dealer's warranty, while Ling forked out S$5,995 for the 12-volt battery replacement, according to ST.

A day after the replacement, Ling's Porsche, which was stationary at the exit of a carpark was rear-ended by the Mazda.

On May 31, 2024, the car was sent to TTS for repair.

The car was originally slated to be returned on Jun. 13, 2024.

However, TTS told Ling on that day that the vehicle could not be collected.

A diagnostic test indicated that the EV battery was faulty and had degraded.

According to ST, the car was held at TTS for about 278 days.

Ling alleged that TTS did not provide substantive updates on the repairs.

TTS asked him to pay for the costs of dismantling the EV battery housing before replacement or repair works could proceed.

On Aug. 8, 2024, Ling's lawyers sent a letter to TTS demanding that they repair the car under warranty, return the prior payment for the 12-volt battery and compensate for loss of use of the vehicle, reported ST.

On Jan. 16, 2026, the lawsuit was ordered to be moved to the High Court after originally being filed as a Magistrate's Court case in 2024.

Both parties will hold their next case conference on Apr. 16, 2026.
