Aston Martin DBX (and DBX707) buying guide

The original DBX has 542bhp and does 0-62mph in 4.5 seconds, with a top speed of 181mph. The DBX707 arrived in spring 2022 with 697bhp (707PS). It gets quicker-spooling ball-bearing turbos, an ECU remap and a new exhaust, and it reaches 62mph in 3.3 seconds. It also drops the torque-converter gearbox for a nine-speed wet-clutch unit and has carbon-ceramic brakes as standard. PistonHeads calls the 707 justifiably the more popular car, at seven in every ten DBXs sold. Each has its own market page: the DBX 707 and the standard DBX.

Aston made small quality and running-gear improvements soon after launch, so a slightly newer car is the better choice. 2022 model year cars apparently bring suspension and reliability revisions, according to Auto Thoughts, along with a mild unofficial facelift: matt plastic steering wheel controls and no leather flaps beside the centre console. Aston steering wheels wear poorly, and the Comfort wheel is much better but rare on early cars.

The proper facelift came in April 2024. From then the 707 was the only powertrain, and the cabin was refreshed around a completely new infotainment system. Pre-facelift infotainment is disappointing, and the later one is much better. The 717bhp DBX S followed in April 2025, with a carbon-fibre roof, a unique grille and exclusive trim options.

Spec counts for more than year, say Luxury Products World and Auto Thoughts: unusual colour combinations and carbon fibre packs are the ones buyers favor. If you are weighing a pricier spec against a plainer one, the DBX price guide shows what each model year is listed at, and how much an Aston Martin costs gives wider context.

Most of the trouble sits in the electrics, the suspension and a handful of recall items.

Weak battery and electrics

A DBX that is not driven weekly can drain its battery, which then upsets the windows, locking and mirrors. A battery conditioner helps, according to PistonHeads, Auto Express and CarChecker.

Fusebox cable recall

Recall 24V-255 covers 2,902 DBXs built May 2020 to September 2023, where the battery fusebox cable nuts can loosen. The result can be stalling, a no-start, or loss of headlights and power steering. The fix is a flat nut and washers torqued to 12Nm instead of 9Nm, free at a dealer.

Engine warning lights

Some cars had repeated warning lights, sometimes with stalling or misfiring. PistonHeads names low fuel pressure, spark plugs or coils, and faulty sensors as the causes.

Oil cooler hoses

A recall covers DBX707s built September 2022 to July 2024, where the oil cooler hoses could split and starve the engine of oil. Confirm it was done.

Air suspension

Bellows can lose pressure and leave the car sitting unevenly after a night, and worn mounts can knock. Rear suspension also has an April 2026 recall for a torque reaction link pin that can slip and crack the lower arm.

Gearbox and steering

Some torque-converter gearbox issues have been reported, and a software update dealt with harsh or hesitant shifts. Steering wheel wobble hit some 2021 cars, and steering column assemblies were replaced under a technical service bulletin.

Front driveline fasteners

A 2021 recall covers loose front propshaft and differential fasteners that can cost you front-wheel drive or stall the engine.

Trim and small faults

Owners' forums report headlight condensation, air-con failure, mirrors that will not fold and premature leather wear on the driver's seat. Auto Thoughts mentions accidental boot opening, which dealers can apparently recode.

Auto Express says a DBX needs a service each year or every 10,000 miles, whichever comes first, with the first three included at no charge. Its UK figures put the fourth service at £2,160 for the DBX and £2,375 for the DBX707. After that the DBX runs £2,400, £1,680 and £660 for services five to seven, while the 707 runs £760, £3,580 and £560. Note how uneven those bills are: the 707's sixth service is the largest on either list.

Auto Express gives official fuel economy as just under 20mpg and puts every DBX in insurance group 50. For the air suspension, CarChecker quotes €1,500 to €2,500 per corner for new struts at a dealer, with a failed compressor adding €800 to €1,200. Those are European figures, not UK or US ones, so treat them as a rough guide to the scale of the bill if a strut goes on a US car.

Find a DBX707, ideally a post-April 2024 facelift car with the better infotainment. If an earlier car is the choice, take a slightly newer one and pick the spec carefully, since colors and carbon packs are what buyers favor. PistonHeads says early teething troubles should have been cured by service bulletins or recalls, which is why paperwork matters here.

Insist on proof that the fusebox and rear torque link work was done, and on a battery that holds above 12.4V. A DBX with every recall completed is reasonably dependable, according to CarChecker and UsedCarStats. One that sits lopsided after a night on its air suspension is the one to walk away from.
