Own an Aston Martin DBX? Don't Trust Your Tire Pressure Monitor After Recall

When a “Set-and-Forget” Feature Isn’t Quite That

Tire pressure monitoring systems (TPMS) are one of those background features you only notice when something goes wrong. They quietly keep tabs on your tires, ready to warn you before things get dicey. For anyone who racks up miles or just wants one less thing to worry about, they’re a real treat.

Of course, not every system gets it right. Some throw up warnings that never seem to clear, others get jumpy over small changes. Still, TPMS usually does its job and earns its spot on the dashboard.

That said, the Aston Martin DBX is the latest vehicle to have glitchy TPMS, and it's now been included in a recall. According to the recall report published by the National Highway Traffic Safety Administration (NHTSA), owners should not trust the system for now due to a problem with how it handles certain pressure drops.

So, What Went Wrong?

The problem comes down to a software coding error in the TPMS. In some Aston Martin DBX models, the system might not catch or warn you when tire pressure quietly dips below the safe limit.

It started when Aston Martin updated the DBX’s electronics during production. The new setup needed fresh coding and a reset, but not every vehicle got the update. That means some TPMS modules aren’t calibrated properly. In practice, the system will still catch a sudden flat, but it might miss a slow leak that creeps up over days or weeks.

That’s where things get risky. If a tire quietly loses air, you might not spot it until it starts to affect how the DBX handles or brakes. No crashes have been linked to this yet, but missing that warning could set you up for trouble.

The fix is simple: Aston Martin will update the TPMS software so it catches underinflation like it should. The update takes about 12 minutes and won’t cost owners anything.

What Owners Should Do

The recall affects a wide range of DBX models, including 2025 and 2026 vehicles built from May 2024 to February 2026, plus 2026 DBX S units made between September 2025 and February 2026. More than 1,000 DBXs in the US need the update, and more in other countries will receive the same fix.

You don’t have to park your DBX, but it’s smart to check your tire pressures by hand until the update is done. Dealers started getting the word out in March 2026, and owners will get official notices between April and June.

The next move is easy. Just book a visit to your Aston Martin dealer and get the software update. It’s a quick job that brings your TPMS back up to spec. Until then, it’s worth going old-school and checking your tires yourself.
