Well here goes. My 01 SSEi has had problems from the get go; power window failings, fuel pump, trans, leaking in the trunk.

Don't have any steering problems yet, and hoping I don't.

Just recently, my cat converter is making very loud noises.

You know for the money I have spent on my car, I could have bought a new one. Love the car, but hate the cost of keeping it running.

Did you ever find out what the shaking was? I know this post is years old, but I have the exact same problem. Thanks.

I own a 1999 Bonneville SSEI supercharged. It has 252,000 miles on it and I love my car.

The air conditioner went out, it needs the part that makes the heat and air come through the vents. Heat and/or air only comes from the top window vent and side window vents.

Also, I have an oil leak coming from valve cover.

Basically that is the worst with my car. However I'm trying to get these things fixed without getting ripped off. Any suggestions? My husband is not mechanically inclined.

Had my cat cut off and a straight pipe put in its place... saved a lot of $$$.

They make an extension for the O2 sensor, thereby pulling it back a bit out of the exhaust stream, fooling the computer. They also make an O2 sensor that plugs in between the sensor and the plug, and they're around $80 or more. Mine was like $20 and goes between the sensor and the pipe. These cars, when older, spew a bit under certain situations and trigger the light. I've heard of folks replacing cat converters, thinking they were no longer doing their job and still having the light. My best friend for 40 years (and a mechanic for 30) was surprised I found the fix. Hasn't come on since, and it's over 1 year now!

We own a 2001 SSEI and were told that the vibration in the steering wheel was caused by warped rear rotors. So we had an entire brake job done on the front and rear, and all rotors were replaced. Now we are being told that it may be the ABS pump. We are investigating that now.

Hello to all, I had this same problem with my 2002 Bonneville. Checked into the struts & strut mounts, I replaced the whole assembly two weeks ago & haven't heard any popping or clanking noises. I got the parts online @ rockauto.com, spent $60 each, but it is the whole assembly with springs; the local auto parts store wanted $55 each just for the strut mounts.

Did you just have your wheels rotated? If an impact tool was used on a highest setting, it can warp your rotors. Have them use a hand torque wrench set for the correct torque.

I have probably owned close to 50 cars. My best was my 1990 Bonneville as far as dependability. It also rode very nice and was roomy. My next best was a new Acura Legend. I know this is a newer Bonneville on this review. The instrument panel alone on the higher end Bonnevilles is absolutely amazing for the era.

My SSEi is doing the same thing with the A/C. My husband charged it, but it's still blowing hot air on the driver's side. Someone said maybe the A/C power switch or the actuator (whatever it's called). How much Freon does it use? And where is the power switch at? What could be making it not work?
