A Texas dealership has made headlines by offering a 20-year, 500,000-mile warranty on a used diesel Chevrolet truck. Josh Letsis, president of Always Auto in Wichita Falls, Texas, showed off the offer in a viral TikTok clip. In the video, he walks a potential buyer through the details of the warranty on a diesel truck that already has 150,000 miles on it.
Letsis described the coverage: “It’s 240 months, 500,000-mile warranty that, as you can imagine, will pay for itself. Kinda pricey, obviously.” The warranty costs $5,500 upfront and comes with a $100 deductible per repair visit, not per individual item. So if multiple issues are fixed in one visit, the buyer only pays $100 that time.
The warranty broadly covers the drivetrain and other major mechanical components, but does not include wear-and-tear items like belts and hoses. Buyers can also purchase add-ons to extend coverage to electrical systems. When Letsis mentioned a shorter, lower-mileage alternative, the buyer quickly dismissed it, saying, “Oh, only 36,000 miles.”
Long-term warranty deals like this one always come with strict maintenance conditions that can void coverage
The buyer on the call shared that he had already seen the value of extended coverage firsthand. He said, “I’ve had half of my engine rebuilt,” and estimated he had “at least $20,000 worth of work done on my vehicle” under a previous plan. For buyers like him, a comprehensive long-term warranty is a practical financial decision, not just a sales pitch.
Diesel truck repairs can be costly, as one Ram truck owner discovered when she was hit with a $4,000 dealership repair quote after a fueling mistake. The real talking point, however, has been the fine print. Viewers were quick to point out that extended warranties like this one often come with strict maintenance requirements.
One commenter stated, “The catch is if you do not let the dealership do the maintenance work it will void the warranty.” Others noted that similar “forever warranties” in their areas require specific rules around oil changes and inspections, and that missing a service window can void the coverage instantly.
Letsis maintained that the video was a real, unscripted customer conversation and not staged for social media. He also said that buyers interested in this type of long-term coverage tend to already understand what they are getting into. In his experience, these buyers are thinking, “I’m just gonna drive it forever and ever and ever,” and they already know that diesel trucks are expensive to maintain and repair.
On the topic of maintenance requirements, Letsis did not see them as unreasonable. He stressed, “If you do the things you’re supposed to do… you’ll have no issue with coverage.” He believes most warranty claim problems happen when routine service has been neglected over time, not simply because of one missed appointment.
Pricing is the number one consideration for many car buyers. A Texan writer recently revealed on social media how one simple sentence can help you lower the price of a car. For anyone considering an extended warranty on a used vehicle, understanding the maintenance terms is essential.
Common requirements include following the manufacturer’s recommended service schedule, using ASE-certified mechanics or authorized repair shops, and keeping detailed records of all maintenance and repairs done, according to Endurance.
Failing to meet any of these conditions can void the warranty entirely, leaving the owner responsible for all repair costs. A 500,000-mile warranty sounds impressive, but reading and understanding the fine print is what determines whether it actually pays off.
