An isolated but severe incident of wheel separation has been reported. Estimated repair cost: $500 - $1,000.

Powertrain Control Module (PCM) Leak

A recall addresses a potential leak from the transmission control unit cover, which could lead to automatic transmission oil leaks into the control unit. Estimated repair cost: $5,000 - $6,000.

Some owners, particularly of earlier models (2020-2021), have reported higher-than-expected oil consumption, with 'add oil' alerts appearing between scheduled changes. Estimated repair cost: $150 - $300 (for oil changes).

Heat/Overheating (Track Use)

Under extreme load, such as track driving or in hot weather, the Supra may experience elevated temperatures, potentially leading to limp mode or reduced performance. Estimated repair cost: $200 - $1,000+.
