2020 Toyota GR Supra
The 2020 Toyota GR Supra marked the return of an iconic nameplate, developed in collaboration with BMW and sharing many components with the BMW Z4. The 2020 GR Supra was available with a single engine option: a BMW-sourced 3.0-liter turbocharged inline-six engine, producing 335 horsepower and 365 lb-ft of torque, paired exclusively with an 8-speed automatic transmission. The GR Supra was praised for its sharp handling, powerful engine, and distinctive styling. However, some common complaints include limited headroom, small trunk space, and a perceived lack of Toyota DNA due to its BMW underpinnings. Some owners have also reported certain mechanical and electrical issues.

- Estimated Cost to Fix: $100 - $500+ depending on the severity and shop rates.
Interior
- Rattling Noises
- Description/Symptoms: Rattling noises emanating from the dashboard, door panels, or rear cargo area. This can be caused by loose trim pieces or poorly secured components.
- Solution: Identify the source of the rattle and secure or replace the affected component. Some owners have had success with adding foam or felt padding to reduce vibrations.
- Estimated Cost to Fix: $50 - $300+ depending on the complexity of the repair.
Summary
The 2020 Toyota GR Supra offers impressive performance and striking looks, but it isn’t without its potential issues. Engine oil leaks and transmission harshness are notable mechanical concerns, while electrical glitches in the infotainment system can also be frustrating. Body panel alignment issues and interior rattles, while primarily cosmetic, can detract from the overall ownership experience. The severity of these issues varies, and many can be addressed with software updates or relatively minor repairs. However, more extensive repairs, such as transmission or infotainment system replacements, can be costly. Potential buyers should be aware of these common problems and consider having a pre-purchase inspection performed by a qualified mechanic.
