The 3.2-liter V6 engine Alfa Romeo 939A000 was produced at GM factories from 2005 to 2010 and was installed on such popular models of the Italian concern as the Brera and the similar Spider. The motor is based on the GM LU1 block, but it has its own cylinder heads, plus Twin Phaser phase regulators.
The JTS-engine series: 937A1000, 939A5000, 939A000.

Disadvantages of the Alfa Romeo 939A000 engine
- The most well-known problem with this engine is the not-so-durable timing chain.
- The resource greatly depends on the oil change interval and sometimes chains are changed at 50,000 km.
- Like all units with direct injection, this one suffers from carbon deposits on the intake valves.
- Keep the radiators clean, as overheating immediately breaks through the cylinder head gaskets.
- Also, engines of the first years of production suffered from rapid destruction of the catalyst.
