The Acura brand was a mere shadow of its former self by the mid-2000s. The Integra was discontinued and the cars became decidedly more boring. The TL was based on the Honda Accord and the car was not without faults (via Readers Digest).
The Acura TL was not a bad car when it came to the refinement factor. But the reliability was not the best and a lot of the tech was untested. The performance of the TL didn’t fall in line with the image of the Acura brand. There were much better cars to choose from during this era than the TL.
