Serpentine Belt replaced at 20,000mi.
Water Pump replace at 20,000mi.
Electric window motors replaced twice within 2 years.
Factory tires didn't make 20,000 miles.
Rear window was poor fit, lots of sealant used.
Trunk leaks in heavy rain.
Fuel cap release failed.
Despite all the above mentioned problems this is probably the most comfortable performance, luxury car I have owned.
Good high speed handling qualities, over-steers a bit which takes getting used to.
Great acceleration both from a stop and passing. Super charger a must on the 3.8 six cylinder.
Super gas mileage, 29-31 on highway with a very generous fuel tank.
Very quite at all speeds.
There are some warts.
The doors are very heavy, especially on a slope.
Rear seat access is difficult, but once seated very comfortable.
Slope of the roof invites water into the doors when opened in the rain. Results in the window motors failing.
Seat belt recall not well publicized.
Everything is expensive to fix.
Leather seats are not good quality (read thin), Buick makes fine leather interiors why not in the Riviera?
I agree with this person on all items except the "1994" Buick Riviera was never produced.

Ha-ha, lol. You beat me by 2 years! There is no 94 Riv! Maybe he has the only one!
