Known issues on the 2020 Acadia. The federal record for this year runs to six recalls. Two concern over cured tires that can break in the sidewall or shed a tread belt. A fuel pump jet nozzle left with a manufacturing burr can block and starve the engine into a stall; a roof-rail air bag inflator diffuser that was not properly crimped can separate as the bag fires; a start-stop accumulator endcap missing bolts can leak transmission oil and cost propulsion; and improperly crimped rearview camera cable connectors can leave the driver without a rear view. Complaints total 99, led by the electrical system at 21, the power train at 19 and steering at 18.
