Today's most powerful V8-engined Aston Martin has been hit with a safety recall. As it happens, certain models produced for 2023 and 2024 feature oil cooler hoses that may burst due to a manufacturing issue. As per documents filed by the Gaydon-based automaker with the federal watchdog, the supplier changed the oil cooler hose winding process, resulting in a compromised wall.
A thinner than normal wall could potentially lead to a sudden burst while driving, resulting in a loss of oil pressure and – naturally – of engine oil. Bear in mind that losing oil could result in the engine seizing, which increases the risk of a crash, whereas oil coming into contact with a hot component increases the risk of an engine compartment fire.
Thankfully for Aston Martin's legal team and the subject owners, there are no reports of crashes or fires caused by this defect. Affected vehicles were produced between October 11, 2022, and June 30, 2023, at the home of the DBX, namely the Aston Martin Lagonda St Athan facility in South Wales.
India-based Imperial Auto Industries produced the iffy hoses, which bear two part numbers (PY83-6B747-CB and PY83-6B748-CB). The British automaker became aware of this condition in June 2023 after a brand-new DBX707 suddenly lost oil pressure during a test. The system has a nominal operating pressure of 7.5 bar, whereas the rolling road test increases operation pressures to 15 bar.
One month after the aforementioned rolling road test, Aston Martin became aware of a field report alleging an oil cooler hose that had failed. Uprated pressure-tested oil cooler hoses were introduced in DBX707 production in June 2023. According to Aston Martin, they can handle 25 bar of pressure.

Dealers have already been instructed to replace subject hoses, while owners will be informed via first-class mail beginning April 22, 2024. Owners can easily determine whether their SUVs have been recalled or not by running the 17-character VIN on the automaker's and the NHTSA's websites.
Although the United States doesn't use the metric system, Aston Martin The Americas lists the DBX707 with 707 metric ponies. In old money, that would be 697 horsepower. Peak torque is rated at 900 Nm or 663 pound-feet, enabling a 0-60 time of 3.1 seconds and a 50-75 pull of 1.9 seconds.
Top speed? That would be 193 miles per hour or 310 kilometers per hour, making the DBX707 one of the fastest SUVs in the world. Ferrari, however, advertises the V12-engined Purosangue with a top speed of 193-plus miles per hour. Whoever may have the upper hand in this regard, it does not really matter because both the DBX707 and Purosangue are designed to impress in the twisties.
The DBX707 and DBX will get better for 2025, for Aston Martin prepares a substantial overhaul. In addition to more structural stiffness and a revised suspension setup, prospective customers should also look forward to touchscreen infotainment with cordless Android Auto and Apple CarPlay.
After a 1:43 scale model of a Ferrari 250 GTO sparked Mircea's interest for cars when he was a kid, an early internship at Top Gear sealed his career path. He's most interested in muscle cars and American trucks, but he takes a passing interest in quirky kei cars as well. Full profile
