“A few months back I began noticing that my check engine light came on. Would take 10- 15 mins to fill up gas tank. Sensor was triggered every few seconds, suggesting gas tank was full, but it was not. Took it to the dealer and was told there was nothing wrong with the car. With in the last month I have been noticing that rear automatic locking seat belt is not staying locked. Child car seats do not stay secured. Car occasionally stalls when started, and air bag light does not illuminate to determine if air bag will deploy or not.”

“Emission control system failure. I just had my vehicle repaired for a failing vapor canister purge valve that causes the check engine light to illuminate. This valve is part of the evaporative (evap) emission control system. According to my mechanic, the faulty valve stays in the open position which also causes the charcoal from the canister to release into the fuel lines,clogging it. The symptom of this problem causes you to start having trouble filling your gas tank. The gas hose keeps shutting off at the beginning of the fill acting as if there is a vapor lock. …”

“2003 Hyundai Elantra, 138,000 miles. When driving on highway 9/18/10, suddenly began to smell (burning), white smoke from engine, then check engine light came on and temp gauge showed extremely hot - no warning before the engine overheated. Mechanic says problem was clamp in radiator that either corroded or somehow came off. Result is that the entire engine is damaged, and we have to replace it. My concerns are (1) this seemed to happen with no warning. There was no leak or symptoms of problems before the engine overheated and was irreparably damaged. …”

“On march 4, 2006 I purchased a pre-owned 2003 Hyundai Elantra with 33,855 miles from buhler & bitter dodge located on route 35 in hazlet, new jersey. At the time of purchase I was advised that all used cars are certified pre-owned vehicles and are put through a 135 point check prior to being put on the lot. The Hyundai that I purchased passed this 135 point check and still had the remainder of the factory warranty which was 5 years or 60,000 miles. The balance of this warranty would be transferred to the new owner. …”
