Solterra vs Model 3

The pre-facelift Subaru Solterra (2023-2025) suffers from severe thermal throttling in its battery management system, causing DC fast charging speed to drop dramatically and often requiring up to an hour to reach 80% charge. Additionally, the system limits drivers to a maximum of three DC fast charging sessions per day to protect the battery, which significantly reduces practicality for long-distance travel. The 2026 model year refresh addressed this with an improved charging curve and a battery pre-conditioning feature, but no permanent retrofit for earlier models is documented.

The rear-view camera on Model 3 vehicles from the 2019-2020 model years can fail because repeated opening and closing of the trunk damages the coaxial cable feeding the camera, potentially causing a black screen or complete failure. This increases the risk of backing collisions. The issue was addressed in a December 2021 recall that covered 2017-2020 Model 3 vehicles, with a free remedy; out-of-warranty harness repair is estimated to cost a few hundred dollars but no independent cost estimate is available.

Certain 2021-2022 Model 3 vehicles with Autopilot, and some 2020 models, may experience phantom braking where the car slams on its brakes at highway speed with no visible obstacle, which can cause rear-end collisions and erode driver confidence. This was investigated by NHTSA in February 2022 after numerous complaints. Tesla addressed it with free over-the-air software updates, so no owner-paid repair is typically needed.

Front upper control arm ball-joint wear can cause creaking or clunking sounds over bumps and while steering on Model 3 vehicles from 2019-2023, especially earlier builds. This can lead to uneven tire wear and, in severe cases, loss of suspension integrity. Out-of-warranty replacement typically costs between $400 and $900 per side including parts and labor.

Tesla Model 3 vehicles from 2019-2023 can experience premature failure of the 12V auxiliary battery, often within 2-4 years, leading to warnings like '12V battery needs service' and potentially leaving the vehicle inoperable. The battery may fail while parked, causing a sudden inability to unlock or start the car. Replacement at a service center typically costs between $250 and $450 including parts and labor.

In December 2023, Tesla recalled over 2 million US vehicles including the Model 3 from 2019-2023 because NHTSA found that Autopilot's controls may not sufficiently prevent driver misuse, increasing crash risk. The remedy was a free over-the-air software update to add more prominent alerts and checks. No owner out-of-pocket cost is associated with this recall.
