Porsche Faces Class-Action Lawsuit Over EV Charger Speed Issues

Porsche EV owners claim the company slowed chargers, making charging times painfully long. The luxury automaker is now dealing with a class-action lawsuit over its Porsche Mobile Charger Plus (PMC+) and Porsche Mobile Charger Connect (PMCC) devices, which allegedly take twice as long to charge vehicles as advertised.

Plaintiffs argue that Porsche, after discovering overheating issues with the PMC+ and PMCC in 2023, deliberately restricted their output from 40 amps to 20 amps, doubling the time needed to fully charge Taycan and E-Hybrid models. Charging that once took around 9.5–10.5 hours now reportedly stretches to 20 hours, leaving owners frustrated. Lead plaintiffs Paul Herdtner (Taycan 4S) and John Holby (Taycan Turbo) are demanding chargers that function as marketed or full reimbursement for the cost of the devices.

Why This Lawsuit Matters

The complaint states that Porsche advertised the chargers as fast, reliable, and efficient, giving customers confidence to invest in premium EVs. Slower charging undermines the vehicles’ usability, particularly for daily commutes and long-distance travel. Plaintiffs claim Porsche has failed to restore full charger functionality, which they argue diminishes the value of their expensive electric vehicles.

Legal Demands and Potential Outcomes

Filed on September 26, 2025, in the U.S. District Court for the Northern District of Georgia, the lawsuit — Herdtner, et al., v. Porsche Cars North America, Inc. — seeks full refunds, charger functionality, and punitive damages. A jury trial has been requested, highlighting the seriousness of the claims and the potential for substantial repercussions for Porsche if the plaintiffs succeed.

Impact on Porsche and the EV Market

This lawsuit comes at a time when electric vehicle reliability and charging infrastructure are under intense scrutiny. For a luxury brand like Porsche, public disputes over hardware performance can affect reputation and buyer confidence. Tesla, Lucid, and other EV makers are watching closely, as outcomes could shape customer expectations for charger performance and transparency across the industry.

The Road Ahead

Porsche will need to respond decisively, either by restoring charger speeds or facing possible financial and reputational consequences. For owners of Taycan and E-Hybrid models, the case highlights the importance of verifying manufacturer claims and ensuring promised EV performance is delivered. The broader EV market is likely to see increased scrutiny as this lawsuit unfolds, emphasizing how critical charging technology is to the electric car experience.
