What Are the Common Problems With the Buick Envision and Mercedes-Benz GLB?

Braking trouble is the Envision's worst pattern. Owners describe the car braking hard on its own with no obstacle, a "Service Brake Assist" warning followed by a sinking pedal, and steering that locks after an engine stop/start restart. Oil loss and one turbo failure also appear. The GLB's complaints center on a blank instrument cluster, rear spoilers and trim coming off, and cylinder head failures with stalling. The GLB has a crash-linked air bag area, where side air bags did not deploy in a crash. The Envision's crash-linked report sits in the power train.

Which Is Cheaper to Maintain: Buick Envision or Mercedes-Benz GLB?

The Envision averages 0.4 unscheduled shop visits a year. No shop-visit figure is available for the GLB, and the data gives no major-repair chance for either car. Owners do report GLB cylinder head failures and disputes over who pays, so one large bill is a real risk there.

Who Should Buy the Buick Envision vs the Mercedes-Benz GLB?

If you want the lower running cost and the cleaner recall history, shop the Envision. Aim for 2018, one of its strongest years, or a 2025, keeping in mind a newer year has had less time to collect complaints. Skip 2021 and 2022, its weakest years. Before buying, test the brakes and ask whether the oil level has been checked, since brake faults and oil loss are the patterns to watch. If you prefer the GLB and can absorb higher bills, target 2022 or 2023, its strongest years, and avoid 2020 and 2021, its weakest. Check the rear spoiler mounting, confirm every recall has been completed, and ask for proof of any cylinder head work. You should also make sure the air bag warning light stays off on a test drive, because owners report it returning after repairs.
