Owners report a 'Service Brake Assist' message appearing while driving, immediately followed by a brake pedal that is either rock-hard and requires extreme force, or that goes unresponsive and then sinks to the floor when pumped. Two NHTSA complaints on the 2019 describe this at… Repairs typically run $300-$950. Severity: high.
Gen1 Envisions have a cluster of NHTSA complaints describing a front flexible brake hose splitting or rupturing, dumping fluid and producing an instant loss of braking with the pedal falling to the floor.

Second-generation Envisions have a repeating NHTSA pattern of the fuel pump control module failing, producing an engine that dies without warning while driving and a crank-no-start afterward, or that only fires on 7-8 of every 10 attempts. Owners report no warning lights and no s… Repairs typically run $500-$1,400. Severity: high.
2025-2026 Envisions with the 2.0L turbo LSY four-cylinder develop an audible ticking noise from the top of the engine.
