I have my GSX since now 3 months. I also have had my check engine light ON... Cruise control and door ajar light problems... Everything have been fixed and it runs like a new now. Nice car for a first car. Good performances and good on gas. Looks nice and comfortable.
I've had my 2004 KIA Spectra for about 2 months. The day I took it home the check engine light came on. The dealership said it was most likely a "temporary condition" that caused it, and they reset the light.
I've got 1,867 miles on the car and the brake pedal is starting to go all the way to the floor. Dealership says it's most likely a faulty master cylinder, but they are too busy repairing other KIAs, so I can't take it in until tomorrow.
I hope this isn't the start of more and more problems to come.
I purchased a 2004 Kia Spectra about a month ago. Within the first two weeks the Check Engine light came on, the right window had a warped channel run, and water leaked in the driver window. The windows were fixed (driver side still rolls up too tight). They told me the Check Engine light was from not clicking the gas cap three times (3 times only). They reset it and, again two weeks later, the check engine light is on. This is my first brand new vehicle and I hope this doesn't turn out to be a lemon.
I also have a 2002 spectra with major check engine light problems. The car has been in the shop 8 times in the last 6 weeks because of this. Each time the light has come back on it has been a different problem. Never once has it been the gas cap as reported above. The car's computer has been replaced two times so far in three years.
We have a 2003 Spectra with 38.000 miles, our trouble is trim falling off, and we have a rattle when going over bumps. I have been a mechanic for 18 years now, and cannot figure out were this rattle is coming from! And from reading other comments on this page, I have already had check engine on 3-4 times a year! Yup GAS CAP!! Got a new one from an auto parts store, and the problem was solved!
