2021 Tesla Model 3 Complaints

  • Visibility/wiper, forward Collision Avoidance 08/21/2026

    Tesla replaced the windshield on my 2021 Model 3 at the Tesla Service Center in Schaumburg, IL. Days after the installation, following a light rain, a film appeared on the exterior surface of the glass. In the presence of moisture the film hazes over and substantially obscures forward visibility from the driver's seat. The first occurrence was on 8/22/2026 while leaving a venue in heavy pedestrian traffic. Forward visibility was significantly degraded. During that drive the vehicle's driver-assist system issued a take-control prompt and returned control to the driver. The system did not display a reason for the prompt, so I cannot attribute it; I am reporting that it occurred while visibility through the windshield was degraded. The condition is not removable by normal means. Windshield wipers and washer fluid do not clear it. The defroster/defogger does not clear it, which rules out interior condensation. It required manual scrubbing to reduce, and it has recurred repeatedly since....

  • Suspension 06/01/2026

    My 2021 Tesla Model 3 with approximately 70,000 miles developed front suspension problems. It began with squeaking, creaking and groaning, similar to a rusty playground swing, especially while turning or when the suspension moved. The noise was worse in hot weather and progressively became extremely loud and constant during normal driving. I also began hearing intermittent knocking/"bonking" or clunking. I could even hear the suspension when the vehicle compressed as I sat in the driver's seat. There were no warning lights or messages. Tesla inspected the vehicle and diagnosed both front lower lateral links and both front lower compliance links as needing replacement, along with an alignment. Tesla estimated approximately $1,960. CPR EV Repair replaced the diagnosed lower suspension components. After removal, the bushings showed significant visible deterioration, including cracked, torn and separated rubber around the inner sleeves. CPR EV also advised that the front upper control ar...

  • Lane Departure 08/03/2026

    I was driving down Interstate 635 Lane Departure Assist on my 2021 Model 3 pulls me into the lane it senses im departing into when system is set to "assist" (if vehicle sense im straying into the left lane as an example, it will pull me further towards the left lane markings and requires an abnormal amount of effort into recentering the vehicle within the lane I am in). Vehicle has since been driven in "warning" setting since this event with no further issues.

  • Suspension 04/17/2026

    my 2021 tesla model 3 required replacement of both front upper control arms due to premature wear. the vehicle developed suspension noise, and an inspection determined both upper control arm assemblies with ball joints needed replacement. the repair cost was $1,845, including a wheel alignment. i am aware of numerous similar owner reports involving premature front suspension component failures in tesla model 3 vehicles and am submitting this complaint because i believe this may represent a broader safety-related issue.

  • Forward Collision Avoidance 07/23/2026

    The adaptive cruise control on Tesla vehicles is dangerous. The model in question is a 2021 Model 3 but its an issue with many model years. The cruise control tends to get confused and applies the brakes during normal driving leading to very unsafe conditions for the Tesla and anybody behind it. The issue can happen in any environment and from 1-2 times per drive. There are no warnings or indications that the car is about to apply the brakes. The car has not been inspected by a service center but is in good working condition.
