2023 Tesla Model 3 Reliability Report

Cars lose drive power at freeway speed, sometimes within their first 450 miles, and either stop in traffic or show a power-down warning. Other reports cover unintended acceleration while parking or slowing, a steering wheel that seized, a front trunk that pops open on shifting into Drive, turn signals that fail to engage, and safety systems going offline after a reset. Of 36 complaints, 8 involve a crash and 4 involve injuries. Several complaints point out that the rear doors have no mechanical release if power fails. Some report real range far below the displayed estimate.

Rear doors that cannot be opened from inside without power are the most common concern here, and one report describes the car staying locked after a crash. Unintended acceleration while parking accounts for several of the 6 crash-related reports among 36 complaints, and 4 involve injuries. Other reports include a rear drive unit inverter failure at about 3,000 miles that left a car stranded, sudden battery range drops, windshields cracking in freezing weather with no impact, and locks, mirrors and trunks operating on their own.

Two opposite failures show up. In the crash reports, the brakes or automatic emergency braking fail to stop the car even when the driver presses hard, leading to rear-end and off-ramp crashes. One happened at about 11,000 miles. Much more often, the car brakes hard for no reason on cruise control or Autopilot, sometimes many times in one trip. Of 22 complaints, 5 involve a crash and 1 an injury. Smaller patterns include an intermittent Auto Hold fault, regenerative braking cutting out on steep descents, and warnings that disable ABS, traction control and emergency braking together.

Failure to deploy in serious crashes dominates these reports, including totaled cars and one case where the screen claimed a deployment that never happened. Of 13 complaints, 9 involve a crash and 8 involve injuries, the highest share of any category. Several of those crashes followed unintended acceleration or brakes that did not respond. The other reports cover front passenger occupant classification faults that service visits and software updates did not clear, plus one report of the passenger bag staying on with a toddler in the seat.

Front suspension parts fail or come loose early. Reports include upper control arms replaced at 24,000 miles, damaged lower lateral links, a fractured compliance arm bolt, and a front arm that fell out after collision repair, which raises loss-of-control risk. The ride is described as harsh and jarring on wavy roads, with vibration from 40 to 80 mph, rattles, and alignment that will not stay set. Service often finds nothing or disputes warranty coverage. Of 11 complaints, 1 involves a crash. One report notes the car has no spare tire or jack.

Bumper covers fall off after driving through heavy rain or puddles, and Tesla has declined warranty coverage by blaming water. That is the clearest pattern. Other reports include an underbody shield coming loose in rain and knocking out collision warnings, trunk struts failing so the trunk slams shut or will not latch, a rear side window shattering at highway speed, and a door swinging back onto a driver's head. A sharp lower door edge cut one passenger's leg. Of 9 complaints, 1 involves a crash and 3 involve injuries.

Seat mounting bolts are loose or missing, both on new deliveries and after a seat replacement, so the seat rail can lift or the seat can tip forward. That is the main pattern. Other reports describe a driver's seat that adjusts itself while driving, a seat that collapsed backward in a rear-end crash and injured the driver, and plastic trim under the seat that snags clothing and trips people. Of 7 complaints, 1 involves a crash and 2 involve injuries.
