I took it completely apart and ran a brush through the entire vent system to make sure it was cleaned. I resealed the joints where connections are made with the proper tape material. I will try to describe the vent system. From the outside of the house, the vent comes into the house and connect to a 90 degree elbow. Then there is about a 13 foot straight vent. That connects to another 90 degree elbow and goes on for another 6 feet before connecting to another 90 degree elbow. A straight drop of about 6 feet to the floor, connected to another 90 degree elbow and finally the flexible vent connecting to the back of the dryer. I believe, as per the manufacturer manual, it says to use no more than four 90 degree elbows. I also note that my previous 15 year old dryer, never had this problem. The only other idea I can think of is to replace the flexible vent that connects to the back of the dryer to the vent system, with something else. What, I don't know.

M1502.6 Duct length.
The maximum length of a clothes dryer exhaust duct shall not exceed 25 feet (7,620 mm) from the dryer location to the wall or roof termination. The maximum length of the duct shall be reduced 2.5 feet (762 mm) for each 45-degree (0.8 rad) bend, and 5 feet (1,524 mm) for each 90-degree (1.6 rad) bend. The maximum length of the exhaust duct does not include the transition duct.

With 4 90 degree elbows no wonder the air isn't moving
I do agree that the older units has stronger fans and likely why your older unit worked ok

Any other thoughts or suggestions? Someone was telling me that I could buy an insert for the duct that acts like an additional fan. Would this help or is it a novelty item? Any other suggestions on this one anyone? My only pain point is that the dryer worked fine for about a year. So if the vent system was not proper, and it's not, my assumption is it wouldn't work from the start.

A number of factors in play
The vent fan on your dryer may have lint and dust build up on the blades causing them not to move sufficient air. Couple that with the length of vent pipe and I would suggest an exhaust booster. It need to be placed 15 to 20 away from the dryer, up in the attack. Search the web for Fantech 110. This unit will be sufficient as it moves 167 cubic feet of air per minute. And yes its not a gimmick, most new construction here installs them. That was the building code i had quoted previously.

Any advice or information on how to check/clean that vent fan on the dryer? You mentioned the fan goes up in the attack. The dryer is in the basement.

Oh my bad
We don't have basements here in floirda.
The vent booster should be placed inline about 15 feet away from the dryer which in our application would be in the attic.
For you that may be just before the elbow between the 6 foot run and the 13 foot run.
