OK, I will first like to say I am considering purchasing another 2001 Mazda Millenia. I owned my first Millenia in 2002, and after the warranty expired, I traded the car because I did not want to pay for maintenance.

Now 2 years later, after going through four cars, I am again considering purchasing another one.

For what it is worth, I think everyone should stay away from the Mazda dealers, because I think they are a rip-off.

The car is beautiful and the ride is beautiful. For what it is worth, I haven't had another car that I liked as much as the Millenia. If I purchase the vehicle (after having a emissions test LOL) I plan on buying aftermarket O2 sensors if I incur problems with them.

Also, I found after market catalytic converters for $200 for both at http://www.autopartswarehouse.com/. I have a mechanic that works on my 2000 Tahoe, and plan on calling him before I purchase the vehicle to get rough estimate to do the work (just in case). I will post any additional info that I find that might be helpful that I come across.

I am one that has been on both ends, and think if the car is that bad, why are they so hard to find? Any thoughts?

In the post dated "13th Dec 2007, 11:18," I noticed that you were able to have your ECU programmed by Jet Performance and this "woke up" your engine. Just how much waking up did your engine get? What exactly was done? Was a chip added? Pardon my ignorance, but is this an actual place to have work done on the Millenia? I am in the NYC area.

I have had my Mazda MPV since 2003. I purchased it brand new. I started having problems at about 80,000 miles. I have replaced all 4 O2 sensors, a couple more than once, the ignition coil, left front CV joint, and a leak in the oil pan.

My cousin is a mechanic and told me that Mazda is notorious for the O2 sensors burning out, especially if it rains a lot. He said water gets in where the windshield meets the hood and burns them out eventually.

It is almost paid for so I will keep it for a while, but will never buy another Mazda!

How's it going my fellow Millenia family? Good, I hope. As for for me, I'm very happy. I'm a 19 year old kid in south Florida, and I recently got my hands on a 2001 Millenia S. The car is decent, though I have experienced rough shifting and bad o2 sensors.

When I noticed that my Millenia was shifting strangely, I automatically went to the local AAMCO transmission shop. When they told me that it wasn't my transmission... I was pretty relieved. They told me that it could be bad spark plugs, so I went to the dealer and had them changed. Since then my milly has been performing like new! If any of you have also had this problem, you should try going to a transmission shop and see what the problem is, and if they can possibly help you out with an opinion.

As for my o2 sensors, can anyone tell me if the two front upper sensors hard to get to? The dealer wants to charge me $225 for each sensor. Think that includes labor, I think. I certainly hope so. Also: how long should it take to change them?

Besides the two aforementioned problems with my milly, it is a dream. I'd been wanting this car since 2001, and now I have it! I also hear a lot of people complaining about the high maintenance of the car? What do you expect? It's an entry luxury car. But I don't care: I still love my baby! As for the o2 sensors, can anybody please let me know? Email me at babyboy754@tmail.com. Thanks!

I just bought an 02 Millenia. I guess I will see what happens?

I have a 2000 Millenia S that ran fine until about 60k, and then started having the typical check engine problems. Over next 2 years replaced 3 coil packs at dealer for 300-500 each, depending on location (bank), vacuum T's broken, but took forever for them to figure out, corroded 17"chrome wheels (on inside where tire bead meet rims) an admitted defect by dealer, but out of warranty.

Ruined two tires because the wheels would not hold pressure due to corrosion.

Now at 92k both axle boots torn which resulted in worn axles and replacement.

Check engine light back on - dealer says needs 2 O2 sensors and both cat converters. Took it to a reputable foreign car repair shop -- no reading on O2 sensors, maybe needs one cat.

In summary, am fixing axles (not at dealer) to make it safe to drive and them getting rid of it. Anyone reading these posts by all the folks having similar costly repairs with this car, should have their head examined if they find themselves considering buying a used Millenia!

I am thinking of buying a millenia 2001 model, sedan. Mileage is 240,000 kms or about 110,000 miles. Pictures of the car look good and interior is wood grain, automatic... any advice or thoughts? Should I or shouldn't I? RJ.

I purchased a 2002 Mazda Millenia in October of 2007. Immediately, the check engine went on which is a common problem in the car. On really cold days, the TCS OFF light will come on and stay on until the car warms up. It's fairly decent on gas for my 15 minute commute to work each morning. The only major issue I've encountered has been the Harmonic Balancer coming apart and needing to be repaired. Other than that, I love the car but I don't expect to keep it for too much longer.

I have a 2001 Mazda Millennium, and around 49000 miles the knock sensor went out.

At ~80000 miles 1 or 2 O2 sensors when out.

At 92000 miles, light came on and it was both cat's. at 105000. I still have to replace the cats, but now the knock sensor is out as well.

I have gotten the local dealer down to $2200 to match a local repair shop. Yeag, to MATCH their price. jeez, I will have spent over $4000 when this is all said and done.

Does anyone know if there a service manual available for this car? I can't seem to find one.

I believe there are Chilton manuals for Millenias. You can also find lots of info on the cars at Mazdaworld.org, where there is a pretty good sized group of Milly lovers, who have had every issue known to man on this vehicle.

I own a 2001 Millenia; the jerking and bucking will stop if you replace the air duct. It's a $90 part, so ask your mechanic. The engine light and all this replacing of O2, cats, etc. didn't do a thing until this air duct was replaced.

I have a 1999 Millenia with 146,000 miles on it. I started it up this morning and it seemed to be running rough. As I drove about a mile to my daughter's school, white smoke started pouring out the exhaust pipe. The temperature gauge pegged to hot, so I pulled over and turned it off. I'm thinking head gasket; at least there is no water in the oil, which makes me think head gasket. Anyway, with 146,000, am I asking for more trouble if I just have the head gasket fixed?
