The Toyota Crown Signia launched in September 2024 as a 2025 model, so taking into account the annual miles covered by the average American motorist, the earliest Crown Signias should’ve covered around 15,000 miles by now. But one Crown Signia driver has already hit over 150,000 miles—roughly 10 times more than the average—in his 2025 Crown Signia. The owner, Justin Thornell, posted the feat on the Toyota Crown Signia Facebook group, while also explaining the maintenance he has done and his goal to hit a million miles in the SUV.
Possibly The Highest-Mileage Crown Signia

Thornell shared a picture of his odometer on January 23, 2026 (no pictures of the car’s exterior were shared), confirming that he had covered exactly 150,026 miles at that point. Assuming he had his Crown Signia delivered in October 2024, just after the SUV launched, that works out to an average of 9,375 miles per month. Thornell is a medical courier for a lab, so he spends plenty of time on the road. He says that 99% of his driving is on the highway, where the hybrid Crown Signia gets up to 37 mpg. In the city, the midsize crossover manages 39 mpg, so it’s efficient no matter what kind of driving you do.
One of Thornell’s few complaints about the Toyota is its gas tank size of just 14.5 gallons—Thornell claims he burns through up to 17 gallons of gas per day at times. His only other issue is having to rely on a tire repair kit instead of a spare wheel. Thornell had all the fluids changed at 100,000 miles, and the vehicle just had its 15th oil change, which aligns with the recommended oil change intervals.
“I love this vehicle and since I have a lifetime powertrain warranty, I’m gonna drive it until the wheels fall off,” said Thornell on Facebook. “I should hit 1,000,000 miles in 7.5-ish years!”
A lifetime powertrain warranty isn’t standard, but some dealers may offer this as an incentive, and it works out perfectly for a customer like Thornell who covers an incredibly high number of miles per year.
Modern Toyotas Are Still Built To Last

Thornell’s story is a reminder of how reliable many new Toyotas still are, despite all the new technologies. To be fair, there’s no reason the Crown Signia’s 2.5-liter four-cylinder engine should have had any major issues at 150,000 miles, given that it has had the oil changed on time and because it’s been used mainly for highway driving.
Other Toyotas still support the manufacturer’s enduring reliability reputation. A 2025 study by iSeeCars showed the Toyota Sequoia to be the vehicle that has the highest chance of lasting for 250,000 miles and beyond, and the owner of a 2024 Toyota Land Cruiser has already covered 110,000 miles with no major issues.

That being said, Toyota has run into some issues with certain engines lately. The twin-turbo V6 is the culprit, with machining debris left in the engine resulting in engine knocking, a loss of power, and complete failure in some cases. This recall affected the Tundra, Lexus LX, and Lexus GX.
The V6 appears to be an outlier, though. Most Toyotas are still top choices if you’ll be spending loads of time behind the wheel, and the brand’s extensive hybrid lineup helps to keep running costs down, too. Here’s hoping we’re still around to report on Mr. Thornell’s million-mile Crown Signia sometime in 2033.
