“The front frame and many components of my 2001 Kia Optima have completely rusted out. It currently has 50,000 miles on it and has had many problems since I purchased it. Check engine light is pretty much on every day. I was told it was something to do with the gas cap, although that never really came up as the reason, there was more than that- resulting in multiple repairs. The o2 sensor has gone twice, the brakes have corroded so badly my repairman had to hit them off to remove them. I had to replace all of the brake lines since they all rusted out. …”
NHTSA complaint #10357905, filed 2010-09, 50,000 miles“I purchased my brand new car on august 31,2001. I started having electrical problems 9 months after I bought it. I now have a list of problems from electrical to check engine light, fuel sensors, 2 new batteries etc. I have a long long list of repairs that nobody can seem to fix. I am told the problem has been fixed and then my check engine light comes back on and I am told there are additional problems. Meanwhile, I have been stranded on the highway due to these problems, I have had to be towed out of my own driveway to due the electrical problems. …”
NHTSA complaint #10082360, filed 2004-07, 8,264 miles“Driving and car just died with no warning. Engine is seized. Getting a hard time from dealership because we do our own maintenance. Rep approved taking the engine apart to see what problem is. Dealer put 3 gallons of antifreeze in and it went right out the tailpipe. Oil changed and antifreeze checked a week before incident. Want me to pay $7 a day rental and put me in a rio or spectra. I have an Optima not a little matchbox car. I should get a free loaner because top tech is out and it may take longer than usual to do repairs, if repairs are approved.”
