Do This Don’t Do This
Inform the customer that this is normal operation of the high pressure fuel pump and injectors.
DO NOT replace the high pressure fuel pump and/or injectors.
The 3.0L and 3.6L SIDI engines use a direct injection fuel system that operates at very high fuel pressures. A direct injection fuel system produces a rapid clicking and ticking sound that can be heard from the engine compartment. The sound is more evident when outside around the vehicle or when the hood is open. The sound is more noticeable during idle and is more frequent during a cold start, but lessens once the engine is warm.
The rapid ticking noise on cold start up is the fuel pump (located on the rear of the left cylinder head) building up high fuel pressure. When the engine warm-up is completed, the high pressure fuel pump will continue to tick at a lower rate of approximately one tick per second during idle. The clicking sound is the fuel injectors pulsing on and off under higher fuel pressures. This sound is a normal characteristic of Direct Injection Fuel high pressure fuel system.
DO NOT attempt to repair or replace any parts for this kind of clicking or ticking concern. The clicking or ticking sound is not indicative of any concerns with the engine or the vehicle. You may wish to give the customer a copy of this bulletin.

True I just bought a 2013 Buick lacrosse when I test drove this car there was no Clicking or a ticking noise a day after I heard A ticking sound coming from underneath the hood l brought back to dealer they gave me a gm bulletin saying that this was normal if I heard this noise when I test drove I would have not bought this car.
This is bullshit. If the car made this noise when new–no one would buy one. How can you expect anyone to believe this???? You treat people like Morons.
