A sharp rise in thefts targeting GM trucks, particularly popular models like the Chevrolet Silverado and GMC Sierra, has been linked to a major vulnerability in their key-fob systems. A new class-action lawsuit reveals how car thieves exploit weak points in GM’s keyless entry technology to quickly steal vehicles without setting off alarms or showing signs of forced entry. And even the newest models are not immune. With GM only recalling trucks for unrelated engine issues and no official fix for this theft risk, truck owners are left to take matters into their own hands.

Combined with rising vehicle values and limited inventory, these vulnerabilities have made GM trucks irresistible targets. Anti-theft precautions, awareness, and extended warranty coverage can all help safeguard your investment.

Why Are GM Trucks Being Stolen So Often?

Car theft has surged in many major U.S. cities, but General Motors trucks (particularly the Chevy Silverado) have become prime targets. A major contributing factor is a vulnerability in their key fobs and keyless entry systems, which allow thieves to easily unlock and start the vehicle. A recently filed class-action lawsuit alleges that GM knowingly failed to implement adequate anti-theft protections in its keyless ignition technology, making it simple for thieves to exploit these weaknesses.

Unlike traditional thefts that involve broken windows or hot-wiring, these modern thefts often leave no sign of forced entry. Criminals use readily available relay devices or key-fob cloning tools to replicate a truck owner’s digital key signal. Once inside, they may use a cheap OBD-II hacking device to reprogram the vehicle with a new key, allowing them to drive away in under a minute.

These thefts are becoming alarmingly frequent in cities like Houston, where Silverado and Sierra models are especially vulnerable. Law enforcement agencies are urging truck owners to take added precautions, as the number of reported GM truck thefts continues to climb.

What Models Are Most at Risk?

The lawsuit currently targets a wide range of GM trucks and SUVs, many of which were sold from 2010 through 2025. Here are the models believed to be most susceptible:

• Chevrolet Silverado 1500, 2500, 3500 (all trims and packages)
• Chevrolet Tahoe and Suburban
• GMC Sierra and Sierra HD
• GMC Yukon and Yukon XL
• Cadillac Escalade and Escalade ESV

Despite improvements in infotainment and powertrain systems in newer models, GM has not yet issued a recall or security upgrade addressing the theft risk associated with the key-fob systems. That means even a brand-new 2025 Silverado parked in your driveway could be just as vulnerable as a 2015 model.

Reports indicate that higher-trim models, which often include push-button start and proximity keys, are even more at risk due to their fully keyless systems. Thieves specifically target trucks equipped with the most modern tech—ironically, the very features owners believe make their vehicles more secure.

How Car Thieves Exploit Key-Fob Vulnerabilities

Signal Relay Attacks

One of the most common methods used to steal GM trucks involves a technique known as a relay attack. Criminals use two devices: one captures the signal from a key fob inside a home, and another transmits that signal to the car. This tricks the vehicle into thinking the key is nearby, allowing it to be unlocked and started without the owner’s knowledge.

Key Cloning and OBD-II Reprogramming

Another method involves cloning the digital signal from a key fob and using an OBD-II port tool to program a new key. These tools, once used by locksmiths, are now easily accessible to criminals online for under $200.

No Forced Entry

Because these techniques don’t require breaking windows or forcing locks, the thefts often go unnoticed until it’s too late. In many cases, even insurance companies are skeptical, suspecting fraud due to the lack of evidence.

Lawsuit Implications

The class-action lawsuit claims that GM could have implemented stronger encryption or rolling code technology, which would render many of these attacks ineffective. Instead, plaintiffs argue that cost-cutting measures left many popular GM trucks, including high-end Silverado trims, dangerously exposed.

The lawsuit could result in damages or pressure GM into issuing software patches or recalls—though as of now, no official fix has been announced.

9 Tips to Prevent a Stolen Vehicle

You can take proactive steps to safeguard your vehicle. Here are some practical vehicle theft-prevention tips:

1. Use a Faraday Pouch or Box: These accessories block wireless signals, preventing thieves from capturing your key fob’s signal.
2. Invest in Physical Deterrents: Steering wheel locks, wheel boots, and brake locks can deter quick getaways.
3. Install Aftermarket Alarms and Trackers: Enhanced security systems that provide GPS tracking or smartphone alerts add another layer of defense.
4. Park Smart: If possible, park in well-lit, secure garages. Avoid street parking or dimly lit areas.
5. Disable Passive Entry: In your vehicle’s settings, turn off passive entry so that the key must be physically used to unlock the vehicle.
6. Routine Key Management: Never leave your key fob near windows or entryways where its signal can be picked up.
7. Software Updates: Stay up to date with GM communications. If a fix or patch becomes available, install it immediately.
8. Window Etching and VIN Tagging: Marking your truck’s windows and components with its VIN can deter resale and make the vehicle easier to trace.
9. Surveillance Cameras: Install cameras near your driveway or garage to increase the risk for would-be thieves.

Even though the risk is higher with GM trucks, simple daily habits can significantly lower your chance of becoming a victim of theft.

Can an Extended Warranty Help After a Theft Attempt?

Many truck owners face thousands of dollars in damage from theft-related incidents:

• Damaged wiring harnesses from OBD-II access
• Broken electronic modules
• Key-fob system reprogramming
• Failed alarm systems

While an extended car warranty or vehicle service contract doesn’t cover components that fail due to damage, it can offer valuable support after a theft attempt. Endurance offers vehicle service contracts, commonly known as extended warranties, that protect your vehicle for the long haul.

This includes useful perks and services such as:

• 24/7 roadside assistance if your truck is disabled
• Reimbursement for towing and rental cars
• Access to a nationwide network of certified auto shops

In short, an extended auto protection plan won’t stop a thief, but it can go some way to soften the financial blow of recovering from one.

The Bigger Picture: GM Recalls and Reputation Concerns

This isn’t GM’s only headache. There have been recent large-scale recalls affecting over 600,000 GM trucks and SUVs due to engine problems. While unrelated to the theft issue, it shows a broader pattern of concern regarding vehicle safety and reliability.

Consumers are becoming more cautious about GM ownership, especially when expensive trucks like the Silverado High Country or Denali Ultimate are compromised by various problems. Trust in the brand is eroding, made worse by GM’s silence on offering a recall or patch for the key-fob vulnerabilities.

And with companies like Honda stepping away from partnerships with GM on electric SUVs, many are questioning whether GM is equipped to handle modern vehicle security challenges.

Add in tariffs, supply chain issues, and now digital security flaws, and it’s clear GM is navigating more than just traditional mechanical recalls. Vehicle owners are advised to stay informed and proactive. Not just with theft risks, but with general reliability and protection.

The Protection You Need for Peace of Mind

The rise in GM truck thefts isn’t just a blip. It’s a trend fueled by exploitable weaknesses in keyless entry systems, increasingly tech-savvy car thieves, and a lack of proactive response from manufacturers. As Silverado and Sierra models continue to top “most-stolen” lists, owners must stay informed and prepared.

Protecting your truck starts with awareness, continues with action, and is backed by solid support, such as from an extended auto warranty. If your vehicle becomes a target, make sure you’re not dealing with the aftermath alone.
