Your fuel tank should not rust prematurely

Your fuel tank should not rust prematurely

Q. I have a 2004 Hyundai Santa Fe with 78,000 miles on it. I just had to replace the fuel tank on it, due to it rusting out! I was quite surprised considering it is garage kept. I didn't have an extended warranty. I contacted Hyundai directly to see if they would at least pay for the parts, to no avail. Is this a common occurrence and do I have any ground to stand on with Hyundai. Thanks for your help. A. I have not seen a rusted fuel tank issue on the Santa Fe in either of our shops, but I did see two complaints online about it for two different 2003 models. Are there lots more of these issues where people are not complaining? I don't know. Fuel tanks will rust out from time to time but I agree, it should not happen with a garage kept car that is less than 10 years old. Did you contact a dealer or did you contact the zone office? If there is a common problem and enough owners inform them of this problem, eventually they will have to address it. I know I haven't been mu ... read more

Make sure to do the online research

Make sure to do the online research

We had a 2005 Chevrolet Cobalt towed in the other day because it would not start and, in fact, had to be jump started several times leading up to that point. We charged the battery but quickly determined the battery was bad and needed to be replaced. After replacing the battery the car started and ran fine but on a test drive we noted the check engine light was on and the car was stuck in second gear, basically a "limp in mode." A conversation with the customer indicated no previous problems like this had occurred. A computer diagnostic pointed to a communication problem with the transmission control module, and possibly a bad module. Since there had been no previous problems with this car, it seemed something just wasn't adding up. We started an online investigation into possible known problems with this system and discovered a fair amount of hits where the transmission control module needed to be replaced after charging the battery or multiple jump starts. Now we wer ... read more

Proper technique is key to change transmission fluid

Proper technique is key to change transmission fluid

Q. I have a question regarding transmission fluid changes. I own two Honda Civics and do not know whether to follow the dash reminder notices or do more regular maintenance. So, for this example, would it be advisable to change the transmission fluid every 45,000 miles or wait for the auto to give me the reminder message, which might pop up at perhaps 60,000 miles? My second question is more direct. Is there a specific test to determine to what degree one's transmission fluid is fouled? I ask this because although I had my transmission changed on Oct. 12, 2012, with 40,000 miles on the car, I was recommended to change it now with 60,000 miles on it -- only 19 months later. The fluid no doubt looks discolored, but without knowing my prior history, maybe that makes it a guessing game for a new mechanic. This has me leaning toward relying on the car's sensor system as to when to make the change. I sure do not think 20,000 miles driven would be enough to warrant a change unless ... read more

Did you know most vehicles have two air filters?

Did you know most vehicles have two air filters?

Q. The dealer I always take my car to send me an email saying On Star had emailed them about a problem I'm having with my car. The problem is with the engine air filter. The check engine light never came on. What is the engine air filter? Is that the regular air filter that you change every six months? A. On Star monitors will vary a little from vehicle to vehicle. It can alert you to what system failed when a SES (service engine soon) light goes on. However, since your light did not go on, I am not sure what the onboard computer is seeing. If an air filter is bad enough to impede the air flow, you might have some drivability issues and perhaps a SES light on. The engine air filter keeps dust and debris from being ingested into the engine, keeping wear to a minimum. There is also a very sensitive sensor known as the Mass Air Flow Sensor that is protected by the air filter. Regardless, it would be a great idea to have the air filter physically inspected. A dirty air filter could a ... read more
