No matter how well they're made, cars in Houston will have design or manufacturing problems. And when the government thinks a problem is really serious for people, they require the manufacturer to issue a recall notice and fix the car free of charge. The manufacturer then tries to contact everyone who owns that type of car to get the recall work done.
These recalls always affect safety, so take them seriously. It's easy to see if a vehicle's being recalled. The government has links on its website - http://www.recalls.gov/nhtsa.html. There are many websites with free recall information and searches. There's CarFax, AutoByTel and the DMV.
Recalls are serious, but not all that common. But sometimes there are less significant issues, and for these, manufacturers issue a Technical Service Bulletin, or TSB, that tells service centers like Kacal's how to repair a frequent or difficult problem. So when vehicle recalls occur, get the work done, and keep you and yours safe.
