Buick Century Custom 6 Cyl 3.1L = P - O - S.

Very light to moderate driving. Already had to replace both motors for front power windows, driver side front seat motor, driver side exterior mirror motor, VCIM system, catalytic converter, thermostat 4 times, and both of the front wheel hubs within the first 5 years of purchase. Just recently had to replace the exhaust manifold, and head gasket. I will tell everyone I meet how much Buick sucks untill the day I die. All I hear are all the horror stories from all the GM mechanics about Buick now. Too bad they weren't that honest with me before they prepped it for my purchase.

Well, owned the Buick for around 3 years now. biggest piece ive ever owned. im a mechanic for another large car company, and believe me, buy Japanese. the Buick has a bad torque converter, the intake manifold gasket is shot, the ABS system never works, and when it does, it likes to talk back. inherited the car, so can't really complain about the repairs, but Jesus Christ, when is America going to build something again that runs like it should. BUY JAPANESE. trust me. i work on them all day, and ive never seen so many ridiculous problems.

I bought this car at 62,000 miles and less than a year later I had the same problem that my mechanic said he sees all the time with this car. The intake manifold gasket had leaked into the engine and the car was losing coolant. At the time i didn't have the money to have it replaced without dexcool, witch is said to cause the problem in the first place, so i loaded up on radiator stop leak, im sure its not recommended but its the only solution i can afford. haven't had any big problems since, just need to put coolant in every few thousand miles and slowly replace with the yellow mix coolant as the dexcool leaks out.

Had to have the radiator changed last fall (2007) and after that we

began to notice a antifreeze/hot smell occasionally, but not all the time. So with the cooler temp. coming due to winter, it was not noticeable and figured the newness wore off and all was good. But on Feb 23 the temperature was warm and after a short trip it was really strong. I checked the coolant level and it was down and so was the overflow tank. Took it to the repair shop and it was determined that the intake manifold gasket was shot. Thanks to GMC and their great gasket makers that should be tarred and feathered and made to pay for this kind of repair. It cost me $1250.which in all fairness included a normal 3k mile service and since at this point the top side was open so went ahead with a 100k mile service. I probably would have traded the car in on a new one before actually reaching 100k (at 73,550 now) but with this kind of money invested, I will have to keep it a few more years. Thats ok because I most likely would have gone back to Buick or GM but will now take the time to look around at what else is out there that we like and doesn't have manifold gasket breakdown. Cheers.

The heater never provided enough heat to defrost the windshield when my wife was driving to pick me up on a very cold fall morning. The windshield kept icing up, and she had to scrape the inside with an ice scraper in order to see. This was a continual losing battle, and she ended up pulling over and calling me to come get her. @ the mechanics garage, our trusty and competent mechanic said the anti freeze had leaked out and we needed a new intake manifold gasket and related replacements: thermostat & sealflushing the system, new anti-freeze, and an oil change because the antifreeze had penetrated the crankcase. The only thing my mechanic did that will need adjustment was that he replaced the anti-freeze with the junky Dexcool. After having done much research, I'm taking it back to be drained and refilled with with some good PEAK Global Lifetime anti-freeze. I'll keep the Buick for now, but my next car will be Japanese.I have now printed out my research with customer complaints from other sites on the web. I will give a copy of my findings to all my friends with GM equipment. My 1992 Lumina has 222,000 miles - no problems; my 1987 Chvey truck has 189,000 miles - none of this junk has happened; and even my 1991 4 cyl Celebrity, which is retired now because it needs tranmission seals - it has never needed so much as a head gasket. It did need a timing chain @ 189,000. GM, flush yourself down the nearest watercloset. You stink for not taking ownership of this problem.

We bought this car for our 16 year old to drive. We do not buy American cars because we figure they are not reliable however, we wanted something that had a lot of car around our daughter. In other words... a big heavy car for safety reasons. This car has been a total disaster. We bought it w/39,000 on it. Since we bought it, two windows have dropped down causing us to replace the pulleys which are extremely expensive about $400.00 apiece. The gas gauge just stopped working one day. Another extremely expensive fix. I should have known. I will (and mark my words) never, never buy another GM car again. It is a joke. No wonder they are in trouble. And the really disgusting thing about this intake manifold gasket leak is that GM knows about it and doesn't do anything to fix the problem. They stink, their company stinks, they are liars and thieves. DO NOT BUY ANYTHING FROM GM THEY ARE TERRIBLE!!! IF YOU DO YOU WILL REGRET IT.
