Known issues on the 2020 CX-30. For the 2020 CX-30, the record shows 3 recalls and 33 owner complaints. On certain 2020 CX-30 vehicles with all-wheel drive, the fuel tank's evaporative vent hose could be disconnected, letting fuel leak from the charcoal canister vent and possibly stalling the engine. That recall covered 12,097 vehicles, and a hose found disconnected is reconnected, with the canister and related parts replaced. Certain others were recalled for front brake caliper bolts that might have been under-tightened during assembly, which could let the calipers loosen, and for a fully opened power liftgate that could partly lower when parked facing uphill. Service brakes lead the complaints with 7; 1 complaint reported a crash. Fuel system, brake and liftgate procedures and diagnostics apply.
