RE: Under warranty &NO OIL in engine!! What to expect?
As an ex-wrench, I can tell you if the engine seized due to a lack of oil, it may be a complete write off. Being expensive to replace under warrantee, the technicians will determine the cause of failure. That is, as long as the owner has the car towed to a dealership as is. I believe the oil either leaked or burned. Leaks are obvious and if 8 quarts of oil is burned over a short period of time, the catalytic converters will show it (toast). I find it highly unlikely that someone forgot to put any oil in the car after an oil change. The engine would have spun a bearing long before the first hundred miles. IÃ¢â‚¬â„¢m unclear why a dealer would use conventional motor oil rather than synthetic. ItÃ¢â‚¬â„¢s also a mystery why the oil pressure sensor failed. I would strongly advise that no one add any oil before the car is dropped off. Any factory mechanic can tell when an engine dies due to a lack of oil (spun bearings are hard to miss). They can also tell if an oil pump still works. A working oil pump with a functioning pickup tube, with an oil filter thatÃ¢â‚¬â„¢s not clogged, combined with every bearing in the block showing signs of running dry, and oil in the sump, usually points to fraud. If they donÃ¢â‚¬â„¢t find oil in the sump, they may look into whether the pressure sensor failed. If they find oil they may be more interested in why someone tried to cover up what really happened.
The good news is, in about a week your friend will have a new factory engine.
