Porsche class action lawsuit overview:

Who: Two plaintiffs filed a class action lawsuit against Porsche Cars North America (PCNA).
Why: They claim Porsche’s electric and plug-in hybrid vehicles take twice as long to charge as advertised.
Where: The Porsche class action lawsuit was filed in Georgia federal court.

A new class action lawsuit claims Porsche Cars North America falsely advertises that its electric and plug-in hybrid vehicles take less time to charge than they actually do.

Plaintiffs Paul Herdtner and John Holby claim Porsche distributes devices for sale and lease that charge the vehicles’ batteries; however, the devices often fail to do so at the advertised speed.

Herdtner and Holby argue a software update Porsche released to counteract the devices’ dangerous overheating only compounded the issue by limiting the devices’ charging rate to half of what was advertised.

“As a result, consumers who purchased or leased the charging devices have paid for functionality that PCNA advertises but that the devices cannot safely provide,” the Porsche class action lawsuit alleges.

Herdtner and Holby want to represent a nationwide class of consumers who purchased or leased a Porsche vehicle and paid for a Porsche Mobile Charger Plus (PMC+) or a Porsche Mobile Charger Connect (PMCC) in the United States.

Porsche knew software update would not solve issue, class action alleges

Herdtner and Holby argue Porsche knew its software update would not solve the issue but has not provided its customers with a “true remedy” for the problem.

“Plaintiffs relied on PCNA’s statements about the ease, convenience and speed of charging their Porsche electric and plug-in hybrid vehicles at their homes when purchasing their PMCCs (and the cars themselves),” the Porsche class action lawsuit states.

“PCNA has made no effort to return the PMC+ and PMCC devices to their full, advertised functionality,” the class action lawsuit added.

Herdtner and Holby claim Porsche is guilty of unjust enrichment, fraudulent concealment, breach of implied warranty and money had and received and of violating the Washington Consumer Protection Act and Illinois Consumer Fraud and Deceptive Business Practices Act.

The plaintiffs demand a jury trial and request declaratory and injunctive relief and an award of actual and punitive damages for themselves and all class members.

In 2024, Porsche was also sued for allegedly failing to disclose a battery defect in its 2020-2024 Taycan electric vehicles.
