Given the lower-quality steels used in the 004B, these engines typically only had a service life of some 10–25 hours, perhaps twice this in the hands of a skilled pilot. Another shortcoming of the engine, common to all early turbojets, was its sluggish throttle response. Worse, it was fairly easy to inject too much fuel into the engine by throttling up too quickly, allowing heat to build up before the cooling air could remove it. This led to softening of the turbine blades, and was a major cause for engine failures. Nevertheless, it made jet power for combat aircraft a reality for the first time.
See above from Wikipedia Ajid, and the answer to your question was that the 262 engine was a fragile beast. This was because production was late in the war and materials were scarce. If the jet engine had been developed earlier the war would have lasted longer (not by much I'd say as the Russians numbered in the millions and boots on the ground counted for more in 1945, or so I think). Earlier development would have seen more reliable jet engines, but I have no doubt a 262 would have crashed over England and would have been reversed engineered very quickly. The appearance of jets focused the allies on our own technology and this would have happened sooner is all. An interesting what if all the same, but the early jet was no war winning weapon.
