Aston Martin has announced the recall of its V12 Vantage coupes, specifically those built for the 2011 and 2012 model years, which equates to 169 units. Fortunately there is no problem with the 6.0-liter V12, as the trouble apparently centers around the programming of the cars' Tire Pressure Monitoring System (TPMS), which is failing to trigger the necessary warning light when cold inflation pressure decreases by 25 percent. Instead the warning light isn't being triggered until the pressure drops by 31 percent.
