What's wrong?
The 2017-2018 Acura Nsx uses left and right fuel tanks connected by crossover pipe couplers. Those couplers are welded connection points that let fuel move between the tanks while keeping the fuel system sealed. In normal use, the welded joints stay tight so gasoline remains inside the tank assembly during driving, parking, and refueling.
On affected Nsx vehicles, the supplier's welding process did not hold the tanks steady or align the heater correctly during production. That left sections of the coupler weld with too little melt depth and pressed-in fit. The coupler can separate from the tank, and gasoline can leak from the fuel tank assembly.
There is no warning sign before failure. A driver should not count on a dashboard light, noise, or change in performance before the coupler separates and fuel leaks.
Who's affected?
Both model years point to the same fuel tank assembly issue, so the VIN check separates included coupes from other Nsx vehicles.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific coupe is included.
What's the safety risk?
A fuel leak near an ignition source can increase the risk of a fire. If your VIN is included, schedule the recall repair promptly and avoid delaying service on the fuel system. Repair will be free at any franchised Acura dealer once available.
What should I do?
- Check your VIN to confirm your 2017-2018 Acura Nsx is included in this recall.
- Wait for Acura's repair notice before scheduling the free left and right fuel-tank replacement.
- Call Acura customer service at 1-888-234-2138 with questions, and reference recall number 18V600 when you call.
- Avoid parking near ignition sources if you smell fuel or see a fuel leak.
- Bring the recall notice to a franchised Acura dealer once the repair opens.
What happens at the repair
At the dealer, once the repair is available, an Acura technician replaces the left and right fuel tanks to address leaking crossover pipe couplers between the tanks. The final dealer repair will be free under recall 18V600, with parts and labor covered. Out-of-pocket repairs before owner notification are handled through the new vehicle warranty, not through a separate reimbursement program, because the warranty provided a free repair for this problem. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
