Ok, Yesterday I went to have my oil changed. I have 85k on my car now. So I firgured I would also get the fuel filter replaced. Well I go out to my car after it is finshed and Boom it hit me. The service Suspension system warning light came on. So I then went to check for codes and a whole slew came up. How does changing the oil and the fuel filter do this? How the heck is this possible? Are you wondering what codes? Here they are IRC U1299, MSM B2111, RSS C1780. The U1299 doesnt even exist the AWH on-board Diagnostic page. There were also 2 more basicly the loss of comminucation with blah, blah, blah. I cleared the codes. None came back. After 2 starts the service suspension system hasnt come back. This car is the most rediculous car I have ever owned, and I'v owned 10 cars. :banghead: Does this make sense to anybody? Also when the suspension warning comes on what actually need servicing? Is there a sensor that triggers this? I have a million questions about this car, its mind blowing. Everytime I drive this car all I think about is whats gonna break next? Does anybody else feel this way. Maybe I'v been spoiled by how well my 98 Lexus GS 400 treated me. I totaled it and lost the best car I'v ever owned in my life, and now im stuck with this thing. Im depressed, and feel like I'v been taken. I can't stop thinking about all the money this thing is going to cost me in future repairs. I only put 1500 miles on it and already have $1400 in repairs. Thats almost $1 per mile. Its enough to drive someone bonkers.

Sometimes these cars put out false codes if the battery voltage to the computer and sensors is low. You might want to clean the connections at the battery plus any others you see. Check the cables for swelling under the insulation which would indicate internal corrosion. Check the battery itself.
FWIW
YMMV
