2021 Buick Envision Problems and Recalls

Source: NHTSA vehicle records, recall and complaint snapshot 2026-10-18. Manufacturer communications retain their separately dated source snapshot. Counts are submitted records, not failure probabilities. One vehicle can appear in several campaigns.

Complaint model names counted: ENVISION. Recall model names counted: ENVISION. Complaint records are deduplicated by ODI number; vehicle recalls are counted by distinct campaign number for this year.

Model-year records

What the 2021 record can and cannot say

The 2021 record contains 23 submitted complaints. The median across this model's matched years is 19 reports. Neither number accounts for vehicle sales or time on the road. Source names: ENVISION. NHTSA source snapshot: 2026-10-18.

Fuel/Propulsion System is the most common displayed component tag, with 6 reports (26.1% of this year's submitted complaints). One complaint can name several components. The share describes reports, not the probability of a failure.

Engine replacement or major internal repair has the highest arithmetic midpoint for parts in the applicable planning estimates, at $8,000 before labor. A paid plan can help only if the component and cause qualify; check existing manufacturer coverage first.

Confirm who pays before authorizing work

A recall remedy follows the campaign and VIN eligibility. A service bulletin provides diagnosis or repair instructions; it does not by itself promise payment. Manufacturer warranty extensions and support programs have their own conditions.

Keep a current problem separate from future coverage

These files do not supply a shop quote. Ask for a diagnosis and written estimate, then check recall remedies or existing coverage. A new vehicle service contract generally excludes pre-existing conditions.

Prepare a useful description for the mechanic →

Each file retains its original source review date. Historical remedy wording can change; check the current manufacturer notice and NHTSA VIN lookup for your vehicle. The separately dated NHTSA counts elsewhere on this page use a different dataset and scope.
