For the first several years, the "low tire pressure" light came on whenever I would make a long, sweeping turn to the left. I would have to reset this switch. This has been fixed during a warranty visit to the dealership.
The dashboard rattled for the first 1 1/2 years of ownership. I had the dealership service department look at it several times. The 4th trip to the dealership fixed this problem. I have now had the car 5 years and no rattles anywhere on the car.
Very quick car with the supercharged engine.
It is comfortable for me at 6'4" tall.
The leather is comfortable, but frankly, of fairly cheap quality.
Save for the early dashboard rattling, this car is still as tight after 5 years as the day I bought it.
I was surprised at how low the gas mileage is (about 14 city and 26 highway). I had a Riviera with the same supercharged 3.8L just prior to this car and it got significantly higher mileage (16 city and 30+ highway).
I have recently bought a 1999 Buick Regal and the same thing with the "Low Tire Light". I think one of these days in the upcoming years there will be a recall for this exact reason.
I am not complaining because the car rides great and I have gone to two separate mechanic shops to put my car on the machine and they both stated there is nothing wrong with the car.
I purchased this car about 5 months ago... I'm thrilled! This is a very fast, well handling car. The low tire light does come on if snow or mud gets in the tires, but that's the only fault I have found. Very quick, I'm on the fire department, and I have stepped on it quite a few times, and it has always pleased me every time it throws me back in the seat. Did I mention they're heated? :)
I've had a 99 Regal LS since new and overall am very pleased with it. The low tire lite warning comes on after every tire rotation, which makes sense because the system monitors tire speed at each wheel and it is thrown off by the tire rotation. I have had problems with the window regulators. The first one was fixed under warranty and I never gave it a second thought. A couple weeks ago the second occurrence cost me over $500 at the dealer (warranty expired). Just yesterday my third one went and I am furious. So I went on line and found other forums where many, many people are reporting this as a major problem in their Le Sabre's, Regals, and Century's. So instead of paying outrageous sums at the dealer, I found them for under $100 online and I'll replace them myself.
I agree with the above mentioned problems - the only things I've ever had to fix on ANY of my Buick Regal's was the window regulators, (ahem) cup holders because they are SO rinky, and heated seat problem, diagnosed, located and soldered by your truly.
My 99 Regal that I am still driving gets terrible gas mileage (19-21 mpg) and the low tire light is on so often that I ignore it completely. I have the same issue with the "Service Engine Soon" lamp. No doubt, there is something that needs attention under there, but the last time it was hooked up to a computer (not at a dealership), it was a general error code of undetermined origin of something to that effect.
The STRANGEST other problem I am currently having is that the A/C blows out freezing cold air on the passenger side and hot air on the driver side. It has dual climate control, so I've turned it on and then off again thinking maybe something had gone haywire there, but Nada. I get the same lame-o explanations at the service shop "Maybe it's your freon", etc. I am truly stumped.
I love the ride, suspension and handling that this car provides and the get-up-and-go for a 4 door (important for cool moms like me) ha. But, I do long for the days when cars were much easier to understand & diagnose & fix without a mechanical engineering degree and physics doctorate. I much prefer to take things apart and learn as I go then to spend hours and weeks just trying to LOCATE the cause of the problem (s). Overall, though, I still love the car. Hate the cup holder. Love the car.
Rach.
Can you elaborate on where you needed to solder the heated seat? My driver's side will no longer heat up. I tested the connector, both orange are 13V, the black is ground, the black with white stripe is ground and the light blue and pink are 8 and 12 depending on the switch setting.
To the user with the aircon issues...
You may find the dual controls work by actuators that move flaps around inside the dash thus piping the warm/cold air to where it is needed.
Clearly, if one side is cold then the aircon is palpably working - its just not getting to the right place so it must be a ducting issue.
It is possible one of these actuators has gone out or a connector has come adrift. No idea how to fix that but I'm 99% sure work to the aircon system would be a waste of time.
