One or two engine mounts broke, resulting in some knocking when accelerating from a complete stop. Had them replaced recently.
The steering wheel is misaligned.
The anti-lock brakes are totally dead.
Climate control issues: AC doesn't work and the fans sometimes make annoying noises when on low speed. The noises seem to worsen in cold weather, and when braking.
Some mild, but noticeable, shaking / vibrations when driving at freeway speeds.
Some frame components are pretty rusty, probably a result of not being parked in a garage for many years.
Some minor electrical issues: passenger side door lock had an intermittent problem with refusing to lock (always works now, at least after a couple tries) and the headlights sometimes need 'motivation' to be turned off.
Overall I think this is a great vehicle. Sure, it has a reputation as a "grandpa" car (yeah, my grandpa originally owned it), but it's powerful and maybe even mean looking in the right light. It has some nice features that make it unique and enjoyable to own and drive.
The car's appearance is somewhat unique in my opinion, almost having the features of a car 10 years older but smoothed out. It looks especially nice in a darker color and it has a respectable amount of chrome. Definitely has a well designed exterior, one of those with nothing looking awkward or out of place.
The body still being mostly metal, with the exception of the fenders, it's pretty durable compared to cars with more plastic.
The interior is also very nice. The seats are a nice gray leather and are very comfortable, feeling almost like sitting on a couch.
It also is very roomy. In addition to the car being a little on the larger side, everything inside feels out-of-the-way. The dash is very set-back and there is plenty of legroom, even with being 6' 4". You'll never feel crowded in this car, even with a full load. People consistently make comments on the comfort and 'roominess' of the interior upon entering. No kidding!
The trunk is also a good size.
After 18 years, the car still runs like new. I have had a couple repairs done, mostly due to rust which is understandable because the car is always parked outside.
Its 3.8 litre V6 has no problem getting you up to speed when you need it to. It's a heavy car, but you'd never know with the way it accelerates. Never had any problems with the engine.
This car's ride is very smooth. The anti-lock brakes finally died, and the repair would be very expensive so I live without them. The Dynaride suspension is amazing. The car feels like it's floating around an inch above the ground. There is definitely a noticeable difference driving over the same bumpy roads in my LeSabre compared to riding over them in another car.
The car turns surprisingly well in general, not just for its size. I very rarely have to correct while parking anywhere because of its turning radius being sharp.
I have very few complaints for this car. Anything that has broken is expected of any car after so many years of use. Some of the components are degrading over such a long time. Things like door locks, headlight switches, climate control buttons are starting to require a little coaxing to work. The climate control is a little awkward to operate having no knobs, just buttons but everything else is easy to use.
Still, it is very reliable. The way it starts up like a brand new car makes me confident it will last for years to come.
