Overview

2021 Tesla Model 3

The 2021 Tesla Model 3 offers a compelling blend of performance and technology, but used car shoppers should be aware of its documented reliability concerns. While it boasts a perfect 5-star NHTSA safety rating across the board, a high number of complaints and recalls, particularly surrounding its ADAS features, warrants careful consideration. The prevalence of 'phantom braking' events, where the car brakes unexpectedly, is a significant drawback that impacts drivability and safety.

Critical Failure Risk

Sudden, unexpected braking events often triggered by perceived obstacles or road conditions that are not actually hazards. This is a significant safety concern and can render ADAS features unusable.

Early detection can help you avoid a $0-$1,500 repair.
