Motor supports (sorento crdi-2.0-4x2,2011)

Good
with less than 65,000 km and 6 and a half years of operation, for 2-3 years it usually gives noise (2-3 different noises) and blows sudden thrusts when raging and disengagement (in the second and third is when they are very evident) that have been increasing in amplitude, which causes the engine to fit too much in my opinion. Mention that I have always given normal use, exclusively good condition, never in the field, always with little load and soft driving (I do not like to force the engine). I would appreciate opinions regarding the state of these tacos and recommendations. These are usually considered as "consumable"? ... or rather as specified useful life components? If someone would have info/data regarding the minimum operation period prior to the replacement (with normal use) of these components, as much as any useful info in this regard. Thank you so much!.
