Acura Recalls 14,648 ZDX EVs Over Brake Pressure Loss

American Honda Motor Co. is recalling 14,648 units of the 2024 Acura ZDX, every one of them an all-wheel-drive model, over a software error that can dump brake pressure without the driver asking for it, according to the National Highway Traffic Safety Administration filing reported on November 14, 2026. The campaign number is 26V735000, and Acura's internal number is CQC.

The defect lives in the electronic brake control module. Faulty software may trigger the anti-lock braking system without warning and bleed off brake pressure, which means the car can let go of the brakes in the middle of a stop. NHTSA's paperwork states the consequence plainly: a loss of brake pressure may reduce braking ability, extending the distance needed to stop and increasing the risk of a crash.

The remedy is a software update to the same module, delivered either over the air or at a dealer, free of charge. The over-the-air route spares owners a service appointment, and for a brake recall that's the one convenience that matters: the fix can reach the car before the owner's letter does. Owners with questions can reach Acura customer service at 1-800-382-2238.

Acura expects to mail owner notification letters starting December 14, 2026. That date is the paperwork milestone, not the repair deadline. Owners of a 2024 ZDX with all-wheel drive — which is the entire recalled population — don't need to wait for the letter to act; the campaign number and the customer service line are enough to check a specific vehicle.

This is the second pass at the same problem. Campaign 26V735000 expands the previous recall, 24V614, which means Acura is widening the net on a brake-pressure defect it already addressed once. Expansions happen when the original remedy or the original population turns out to be incomplete, and a brake recall that needs a second attempt does the nameplate no favors.

The ZDX is Acura's electric flagship crossover, and brake software is now its recurring problem rather than a one-off. Two campaigns on the same system, two years apart, is the pattern owners will remember when the letters arrive in December. The fix being free and deliverable over the air softens the errand. It doesn't soften the underlying fact, which is that the software deciding how hard the car brakes needed correcting twice.

The ledger for owners is short. The car is a 2024 ZDX, all-wheel drive, and it's in the recall. The fault is software, the fix is software, and it costs nothing. What's missing from the filing coverage is any count of incidents tied to this expansion, so the story stands on the defect and the remedy — both documented — and not on a crash tally that hasn't been published.
