The 2023 Supra shares BMW B58 (3.0L) and B48 (2.0L) powertrains with known strengths and specific weak points. Most catastrophic issues trace to the B58's connecting rod bearing failures and transmission cooling inadequacies under spirited driving.
B58 Connecting Rod Bearing Failure (3.0L models)
Occasional · high severity
Typical onset: 40,000-80,000 mi
Symptoms: Metallic knocking at idle that worsens with RPM, Metal shavings in oil during changes, Sudden catastrophic engine failure with no warning, Low oil pressure warning at operating temperature
Fix: Complete engine teardown required. Rod bearings are undersized from factory on some builds. If caught early with oil analysis, bearing replacement runs 18-24 labor hours. If spun bearing damages crank, you're looking at short block replacement at 30-40 hours. Many shops won't warranty bearing jobs alone due to crank journal wear.
Estimated cost: $8,000-18,000
ZF 8HP Transmission Oil Cooler Inadequacy
Common · medium severity
Symptoms: Harsh or delayed shifts after track use or spirited driving, Transmission entering limp mode on hot days during aggressive driving, Burnt transmission fluid smell, Fluid temps exceeding 240°F on OBD scanner
Fix: Factory trans cooler is undersized for performance use. Aftermarket auxiliary cooler installation is preventive fix, 3-4 hours. If already cooked the clutches, you're into full ZF rebuild territory at 16-20 hours plus $3,500-4,500 in parts. Fluid and filter service every 30k mi helps but doesn't solve root cause.
Fuel System HPFP Failure (High Pressure Fuel Pump)
Occasional · high severity
Typical onset: 30,000-70,000 mi
Symptoms: Long crank before starting, especially when hot, Misfires under high load or boost, P0087 code (fuel rail pressure too low), Sudden loss of power above 4,000 RPM
Fix: BMW-sourced HPFP on B58 has known cam follower wear issues. Pump replacement is 4-6 hours (intake manifold removal required). Critical: if pump grenades internally, metal debris contaminates entire fuel system requiring injector replacement and rail cleaning, pushing job to 12-15 hours total.
Estimated cost: $1,800-2,800 (pump only) / $4,500-6,500 (full system contamination)
Transmission Mount Failure
Common · low severity
Typical onset: 25,000-50,000 mi
Symptoms: Clunking when shifting from Park to Drive or Reverse, Excessive driveline lash during throttle tip-in, Vibration through chassis at idle, Visible separation or tearing of rubber mount
Fix: Hydraulic transmission mount tears prematurely, especially with aggressive launches. Replacement is straightforward at 1.5-2.5 hours but requires transmission support. Upgraded polyurethane mounts available but increase NVH. OEM replacement typically fails again by 60k mi.
Estimated cost: $400-700
Starter Motor Intermittent Failure (Recall-Related)
Occasional · medium severity
Symptoms: Click but no crank condition, usually when engine is heat-soaked, Intermittent no-start that resolves after cooling, Works fine for weeks then fails randomly, Jump-starting doesn't help
Fix: BMW starter design has internal heat-related failure. Toyota issued recall for some VINs but not all affected units caught. Replacement is 2-3 hours due to awkward location under intake. Check if your VIN qualifies for free recall service first (campaign 23TA16). If out of recall, you're paying.
Estimated cost: $800-1,400 (if not covered by recall)
Head Gasket Weeping (B58, pre-2023 carryover issue)
Rare · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: Coolant weeping from head/block junction, driver's side, Slow coolant loss with no visible external leaks, White residue around head gasket area, Slight misfire on cold start if coolant enters cylinder
Fix: Early B58 engines had head gasket sealing issues that BMW addressed with revised gasket design. If you have weeping, heads must come off. Job runs 14-18 hours, includes head resurfacing. Machine work adds $400-600. While apart, many shops recommend walnut blasting intake valves (these are direct injection) and inspecting valve stem seals.
Estimated cost: $4,500-6,800
Owner tips
Oil analysis every 5,000 mi is non-negotiable for early bearing failure detection on B58 engines—Blackstone Labs or equivalent
Change ZF transmission fluid every 30,000 mi despite Toyota 'lifetime' claim; use ZF Lifeguard 8 spec fluid only
Install auxiliary transmission cooler before any track or canyon use; factory cooler can't handle sustained performance
Avoid tuning until after bearing inspection—many failures appear after ECU flash increases cylinder pressure
Use Top Tier fuel exclusively; HPFP is sensitive to detergent levels and direct injection systems carbon up quickly
Strong performance platform if maintained obsessively, but B58 bearing lottery and transmission cooling issues make CPO warranty essential for used purchase—walk away from modified examples or track cars without full service records.

BMW of North America, LLC (BMW) is recalling certain 2023 Toyota GR Supra, 3 Series Sedan (330i xDrive, M340i xDrive, M3), 5 Series Sedan (530i, 530i xDrive, M5), 4 Series Gran Coupe (430i, 430i xDrive), 4 Series Coupe (430i, 430i xDrive, M440i xDrive), 4 Series Convertible (430i, 430i xDrive, M440i xDrive), 8 Series Coupe (840i, M850i xDrive, M8), 8 Series Convertible (840i, M850i xDrive, M8), 8 Series Gran Coupe (850i xDrive, M8), X3 SAV (X3 xDrive30i, X3M), X4 SAV (X4 xDrive30i), X5 SAV (X5 xDrive40i, X5 M50i, X5M), X6 SAV (X6 xDrive40i, X6 M50i, X6M), and Z4 sDrive30i, Z4 M40i vehicles. The weld seam of the integrated transmission control unit's cover may not have been manufactured properly, which could allow automatic transmission oil to leak into the transmission control unit.
Consequence: Transmission oil that leaks into the control unit can lead to a seizure of the transmission gears, causing a sudden loss of drive power and increasing the risk of a crash.
Remedy: Dealers will replace the transmission mechatronics module and the automatic transmission fluid, as necessary, free of charge. Owner notification letters were mailed January 26, 2024. Owners may contact BMW customer service at 1-800-525-7417.
