Toyota GR Supra: Common Problems & Reliability Guide (South Africa)
Also covers: Supra
These are issues documented for the Toyota GR Supra in general - things to check for, not a diagnosis of any particular car. Whether a specific car has one depends on its age, mileage, service history and how it was used.

Symptoms to watch for
- B58 plastic oil pump adjusting ring (real, multi-thread-corroborated, non-recalled): the iDrive/multi-information-display oil-level check stopping partway through rather than completing normally, or an 'engine oil pressure too low'/plausibility fault code appearing despite genuinely adequate real-world oil pressure - per the SupraMKV forum's own summarised description, a car whose oil-level check completes normally has likely not yet had the ring crack.
- Tail light condensation (real, multi-thread-corroborated, non-recalled, most reported on 2020 model-year cars): visible moisture/condensation inside the tail light housing - per Toyota's own described technical position, factory-fitted vents are meant to evaporate slight buildup, and some owners report the issue clearing after the lights are run for an extended period, though others report it recurring.
- 19V850000 recall: loss of one or both headlights if the headlight control unit fails - reduces driver visibility and increases crash risk per NHTSA's own consequence text.
- 21V598000 recall: loss of braking assist specifically during engine start, from engine management software - full mechanical braking without assist remains available per the filing's own text, but stopping distance may increase.
- 23V821000 recall: sudden loss of drive power from gear seizure, if automatic transmission fluid leaks into the transmission control unit through an improperly-manufactured weld seam.
- 25V636000 recall: possible short-circuit, overheating, or in an extreme case a thermal event/fire (including while parked with the ignition off) if water reaches and corrodes the starter's electrical relay.
- 26V056000 recall: possible overheating or, in an extreme case, a thermal event/fire from internal starter wear and metallic-debris buildup after repeated start attempts.
What To Check
Unusually for this platform's Supercars-section findings, this card's single most valuable check (the iDrive oil-level check) IS genuinely test-drive/inspection-detectable in under a minute, at zero cost, with no special tooling - a real advantage over most of this platform's other engine-wear findings. Tail light condensation is likewise a real, free, static visual check. The five real recalls are NOT reliably test-drive-detectable (all require a VIN check or a specific fault condition to manifest), and the cross-referenced B58 wear-item cluster carries that card's own detectability caveats rather than new ones specific to the Supra.

This guide summarises documented, sourced findings for the Toyota GR Supra generally. It is not an assessment of any specific vehicle - mileage, service history and condition vary by example. A full AutoLytiQs™ report checks a specific listing for sale against this data plus a live South African market valuation, to tell you whether that exact vehicle is a good buy.
