If you bought a home charger for your GM electric vehicle, you might be experiencing some frustrating and potentially dangerous issues. You're not alone – and a recent class action lawsuit is shedding light on widespread problems with the GM Ultium charger that many owners are dealing with right now.

The Problem with the Ultium Level 2 Charger

In October 2025, two Florida residents filed a lawsuit against General Motors over serious defects in the Ultium PowerUP Level 2 charger. The lawsuit, Kriseman et al. v. General Motors, LLC, lays out some concerning issues that might sound all too familiar if you own one of these chargers.

Here's what's happening:

• The charger keeps tripping its own circuit breaker. Owners are finding their charger suddenly shuts off in the middle of charging, leaving them with a car that isn't ready to go in the morning.
• Overheating is a real concern. When the Ultium home charger does work, the plug can get dangerously hot – hot enough to set off your vehicle's alarm. That's not just annoying; it's a safety risk.
• GM may have known about these issues. According to the lawsuit, General Motors was aware (or should have been aware) of these defects but kept selling the chargers anyway, without warning customers or issuing a recall.

Real Owners, Real Problems

You don't have to look far to find frustrated owners sharing their experiences online. People are talking about it in forums and social media:

• One owner wrote: "My wall-mounted GM Ultium PowerUp charger is failing with the dreaded 'red light'… installed in mid-July and has been working pretty well… until now."
• Another shared: "The charger worked great for the first 2 months. Now I'm getting an orange light shortly after plugging in. Last night… it stopped charging all."

Still others describe chargers that "get hot, lots of breaker resets, sometimes stop charging entirely."

The lawsuit estimates that thousands (possibly tens of thousands) of owners in Florida alone could be affected. And this isn't just a Florida problem.

Why This Is Such a Big Deal

When you buy an electric vehicle, you're making an investment in convenience and sustainability. You expect to plug in at home and wake up to a fully charged car. When your Ultium home charger fails repeatedly, that promise falls apart.

You might find yourself:

• Scrambling to find public charging stations
• Paying for service calls or reinstallation
• Worrying about safety hazards from overheating
• Questioning whether your EV was worth the investment

These aren't minor inconveniences – they're serious disruptions to your daily life.

Which Vehicles Are Affected?

The GM Ultium charger was designed for GM's lineup of electric vehicles built on the Ultium platform. If you own one of these models, you could be dealing with charger problems:

• GMC Hummer EV (2022 and newer)
• Chevrolet Silverado EV (2024 and newer)
• Cadillac Escalade IQ (2024 and newer)
• Chevrolet Blazer EV (2024 and newer)
• Cadillac Lyriq (2023 and newer)

If you purchased a GM-branded Ultium PowerUP Level 2 charger between 2022 and 2024 and you've had charging issues, you should definitely pay attention to this lawsuit.

What the Lawsuit Means for You

The lawsuit defines the affected group as: "All persons who purchased – in Florida and either directly from GM or from a GM-authorized store/dealership – a 2022, 2023 or 2024 model year Ultium PowerUP charger."

While this specific case focuses on Florida, the GM Ultium problems are being reported by owners across the country. Class actions like this can sometimes expand, and they can lead to real solutions – whether that's refunds, replacements, repairs, or other compensation.

Steps You Should Take Right Now

Even if you're not sure whether you're part of this lawsuit, there are things you should do to protect yourself:

1. Keep a log of problems. Write down every time your charger trips, overheats, or fails to charge properly. Note the date and what happened.
2. Save all your paperwork. Hold onto your purchase receipts, installation records, warranty information, and any bills from service visits.
3. Report issues to your dealer. Contact your GM dealer and ask them to document the problems. Get copies of any work orders or replacement records. Some reports suggest GM has internal bulletins telling dealers to replace faulty units – make sure yours is on record.
4. Don't assume it's just you. With so many owners reporting similar issues, this is clearly a widespread problem, not something you did wrong.
