Timing chain on 2004 Acura TSX

The dealership has determined that I need a new timing chain. The car only has 75,000 miles on it. The car was taken to the dealership because the engine light was on and they put it on the computer and there wasn't anything wrong with it just the gauges.

It continued to act terrible no power, sucking up gas and poor performance. They now say it is the timing chain and it would cost $940.

Two questions:

Would there engine damage with the poor chain?
What is the normal life of a timing chain?

The TSX does not have a timing belt, but has a timing chain-like cars of the past. Most timing belts are recommended to be replaced at 60-90K miles. A timing chain should last as least twice as long.

get another opinion on your performance problem . have someone check for codes your car has a timing chain these should last the life of the car . problem is most people dont change there oil and filter enough and use good quality oil and a factory filter religiously . the chain is lubed by the engine oil so if its the chain some one forgot to change the oil and or beat the hell out of it
i have the same problem and i dont beat the car and i change the oil every 3000 miles
but these cars consume oil . Mine does about a qt every 600 miles just started doing it so if your not on top of it that can cause this problem also.
I have had my share of Acuras and the timing chain should last to 100,000 miles. At 100,000 it is good to get the car serviced, they will change the belt. Because the timing belt is in with the engine, if the belt goes so does the engine.
