Tesla Model Y 7 Seat
Problems & Worst Years

Phantom braking is the throughline connecting both model years on record for the Model Y 7-Seat, and it shows up at a scale that dwarfs almost every other complaint category in this dataset. In 2021, 357 of the year's 641 total occurrences — well over half — describe phantom braking during adaptive cruise control specifically, all rated safety-severity. Unexpected deceleration without any obstacle present added another 105 reports, unqualified phantom braking brought in 81 more, and even the fourth- and fifth-place entries, power steering assist failure (28) and outright service brake failure (22), are both rated safety-severity.

2022 tells almost the identical story under slightly different labels: 647 total occurrences, with 186 reports describing random sudden braking during Autopilot mode, 168 more for phantom braking during adaptive cruise control, 114 for generally unreliable adaptive cruise control operation, and 83 for uncommanded slowdowns while using adaptive cruise control. A smaller cluster of 38 reports covers visibility issues. Every single one of 2022's top five entries carries a safety-severity rating, and six of that year's sixteen distinct problem categories overall are rated at that top tier.

The consistency across two consecutive years — both with complaint volumes above 600 and both dominated by unexpected braking events tied to adaptive cruise control or Autopilot — suggests this isn't a one-time software hiccup but a recurring behavior owners have flagged repeatedly across model years. No recall campaigns are attached to either year in the data reviewed, meaning none of this has resulted in a documented manufacturer safety action on record here.

Given how heavily these complaints center on driver-assist behavior rather than a mechanical part, the most useful pre-purchase step is an extended test drive with adaptive cruise control engaged in real traffic, since a brief lot walk-around on its own won't reveal the pattern. As always, these figures represent what owners chose to report to NHTSA, not a measured failure rate, and a thorough test drive plus service history review will tell you more than the model year by itself.
