Nissan GT-R: Common Problems & Reliability Guide (South Africa)
Also covers: GT-R Black Edition, GT-R Nismo, GT-R Premium, GT-R Pure Edition, GT-R Track Edition
These are issues documented for the Nissan GT-R 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
- Inability to select a gear, or a gear not engaging correctly
- Jerking, shuddering, or a harsh 'bang' feel during gear changes
- Burning smell from the transmission/rear transaxle area
- Dashboard transmission warning light, often paired with a limp-home mode restricting engine power
- Sudden loss of drive with the display showing zero or abnormally low transmission line pressure
- Whining, crunching, or humming noises from the transaxle under load
- Loss of reverse gear specifically (a real, GT-R-specific documented symptom - see diagnostic fault codes)
- A known history of launch-control use, especially on a pre-2011 car without a confirmed later TCM software update
- A cold, locked-steering grinding/popping/squealing noise on its own is NOT automatically this card's genuine fault - Nissan's own documented 'tight corner phenomenon' (see diagnosis below) produces a very similar-sounding noise under specific, benign conditions and can be mistaken for, or used by a seller to wave off, the real P17C5/reverse-loss fault documented above
Rough Repair Cost
Independent workshops typically charge R160 000-R550 000 for this, depending on exactly what's needed. The full independent-vs-dealer breakdown is in a full AutoLytiQs report.
What To Check
Early-stage wear (thinning retaining clips, a developing clutch-basket crack) produces no reliable symptom on a short, gentle test drive. A buyer should specifically request a full TCM/mechatronic diagnostic scan (not just a generic OBD-II check-engine read), ask directly whether launch control has ever been used and on which TCM software version, and treat any refusal to allow a proper diagnostic scan before purchase as a serious red flag given how expensive this failure is to repair.
Undisclosed ECU Tuning, Clutch Pack Upgrades, or Other Performance Modifications Masking True Condition and Risk
Symptoms to watch for
- Seller unable or unwilling to provide dyno sheets, tune logs, or itemised modification invoices for a car described as 'stock' or 'lightly modified'
- A dyno or advertised power figure inconsistent with the car's stated model year's known factory output (see diagnosis below for real reference figures)
- Aftermarket parts visible (turbo inlets, intercooler piping, exhaust, wastegates) inconsistent with a seller's claim the car is otherwise stock
- A GR6 transmission that has previously been serviced or rebuilt with reinforced aftermarket clutch packs (e.g. Dodson) without the seller volunteering this
- Reluctance to permit a full ECU/TCM diagnostic read, including flash-counter and stored-code history, prior to sale
Rough Repair Cost
Independent workshops typically charge R2 000-R35 000 for this, depending on exactly what's needed. The full independent-vs-dealer breakdown is in a full AutoLytiQs report.
What To Check
A currently-detuned or reverted-to-stock car will feel and drive exactly like a genuine stock car on a test drive - this is precisely the scenario this card exists to address. The only reliable check is the ECU/TCM diagnostic read (flash counter, calibration ID) described above, not seat-of-the-pants impression or even a clean current fault-code scan.
Wastegate Actuator Rattle (Pre-2011) and Thermostat Housing Coolant Weep
Symptoms to watch for
- Metallic rattle from the turbo/wastegate area, most audible at idle or light throttle, sometimes worsening on cold start
- No associated loss of boost or power in most reported cases (wastegate rattle)
- Coolant staining or a slow weep visible around the thermostat housing neck or hose connections
- Gradual, low-level coolant loss requiring more frequent top-ups without an obvious external puddle
Rough Repair Cost
Independent workshops typically charge R6 000-R158 000 for this, depending on exactly what's needed. The full independent-vs-dealer breakdown is in a full AutoLytiQs report.
What To Check
The wastegate rattle, where present, is typically audible on a short test drive at idle or light throttle and is hard for a seller to fully hide. The thermostat housing weep is less reliably detectable on a test drive alone - a slow weep may not show as an obvious puddle; a pressure test or a careful visual inspection of the housing and hoses is more reliable than relying on the test drive.
Timing Chain Guide and Tensioner Wear Producing Chain Rattle/Slap
Symptoms to watch for
- Cold-start rattle or chain slap from the front of the engine, quietening as oil pressure builds
- A metallic vibration noise most noticeable at idle before the engine fully warms
- In advanced, undocumented-but-theoretically-possible cases: camshaft correlation fault codes if chain slack becomes severe enough to affect valve timing
Rough Repair Cost
Independent workshops typically charge R25 000-R120 000 for this, depending on exactly what's needed. The full independent-vs-dealer breakdown is in a full AutoLytiQs report.
What To Check
A seller who starts the car before the buyer arrives, or who only offers a warm test drive, can hide a cold-start rattle entirely. Requires a genuine cold start, listened to from outside the car or near the engine bay - the same buyer-side check pattern documented for other timing-chain-wear engines in this library.

This guide summarises documented, sourced findings for the Nissan GT-R 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.
