Symptoms to watch for
- Sudden, dramatic loss of engine power
- Check engine light, often accompanied by a misfire code
- Excessive white or blue-grey smoke from the exhaust (oil/combustion gas blow-by)
- Knocking or rattling noise from the engine, in some cases preceding a full failure
- Sudden engine stall - a genuine, safety-relevant symptom given the loss of power steering/braking assist this can cause, as named directly in the underlying lawsuit
Rough Repair Cost
Independent workshops typically charge R65 000-R190 000 for this, depending on exactly what's needed. The full independent-vs-dealer breakdown is in a full AutoLytiQs report.
What To Check
Not reliably detectable on a normal test drive before failure - a healthy-sounding engine can fail suddenly and without prior warning, per multiple real documented cases. A compression/leak-down test and a review of tuning/modification history are the only genuinely reliable pre-purchase risk indicators available; a clean test drive alone provides limited protection against this specific failure mode.
