Known problems with the 2019 Tesla Model 3

5 of the 6 issues we track for the 2017–2023 generation are documented against the 2019 model year, and 2 carry a recall or service bulletin.

• Heat pump failure / loss of cabin heat in cold weather

  majorNHTSA 22V-050 (Tesla firmware 2021.44.30.7)

  2021+ cars use a heat pump whose expansion-valve software could let refrigerant migrate and shut the compressor down in sub-14°F weather, killing cabin heat and defrost. Tesla recalled 2021–2022 cars (26,681 vehicles) and fixed it over the air with firmware 2021.44.30.7+. Separate from the recall, hardware failures of the heat pump sensor/EXV and compressor are among the most reported cold-climate issues; covered under the 4-yr/50k basic warranty, expensive after.

  Typical cost: Free (OTA recall / warranty); ~$1,500–$3,000 for out-of-warranty heat pump hardware

• 12V lead-acid battery dies every 3–4 years (pre-Dec 2021 cars)

  moderate

  The small 85B24LS 12V battery in the frunk area runs constant loads (sentry, computers) and wears out faster than in a gas car, often around year 3–4, sometimes with little warning beyond an on-screen alert. If it dies completely, the car won't wake and the doors need the manual release procedure. Replace promptly when the warning appears; Tesla mobile service does it cheaply, or it's a 30-minute DIY. Cars built after ~December 2021 got a 16V Li-ion battery that eliminates the problem.

  Typical cost: $85–$180 (Tesla OEM battery + mobile service); ~$130–$300 aftermarket/lithium upgrade

• Front upper control arm creak / squeak

  moderate

  A creak or groan from the front end at low speed over bumps or while turning, caused by the front upper control arm ball joints (early arms were prone to water intrusion). Extremely common on 2017–2021 cars; Tesla revised the part. Fix is replacing the upper arm(s), cheap part, moderate labor, and independent shops can do it.

  Typical cost: $200–$600 per side at a shop (~$60–$100/part DIY); up to ~$1,000/side at some Tesla service centers

• Window automatic-reversal (pinch protection) recall

  minorNHTSA 22V-702 (Tesla SB-22-00-013)

  Testing showed the windows could close with more force than FMVSS 118 allows before reversing, a pinch-injury risk. Tesla recalled nearly 1.1 million vehicles including every 2017–2022 Model 3 and pushed an over-the-air calibration fix, no service visit needed. Verify the recall shows closed for your VIN on NHTSA's site.

  Typical cost: Free (OTA update)

• Touchscreen yellow border / banding (early cars)

  minor

  Early screens developed a yellow band around the display edge as the adhesive aged in heat/UV. Tesla fixed affected screens free with an in-service UV-light treatment (originally trying to charge, then relenting under warranty pressure). Largely history now, most affected cars were treated, but check used 2017–2018 cars in sunny states.

  Typical cost: Free (UV treatment under warranty); screen replacement ~$1,100+ otherwise
