Description of the problem	I was on the interstate during torrential downpour, my car's check engine light started flashing and i couldn't accelerate above 2,000 rpm or go over 60 mph. It was very dangerous. I took the car to the dealership to be repaired. After 3 days i picked the car up, and they said they replaced the knock sensor and the car was fixed. Since then this has happened 3 more times. Car is currently in the shop. I started researching on my own, and i read that the knock sensor was an update hyundai added after the recall of the engines in these cars. This knock sensor is actually protecting my car (and me) by putting it in 'limp mode' because it senses something dangerous in the engine. I have contacted hyundai consumer affairs to inform them i am afraid to drive the car because this has happened so many times and clearly is't fixed, and i'm sure it has to do with the recalls they have and engine fires. They've done nothing. Last time i went to get the car the manager at the dealership said that many people were having issues, but hyundai doesn't allow them to actually fix the problem. They have to do work-around fixes instead of the actual repairs needed. The manger said he predicts that "there will be a class action lawsuit because of hyundai not doing anything to actually fix this engine issue". I don't know who to turn to, but i' am afraid to drive the car. I don't want to be driving down the road and the engine catch fire. I'm currently pregnant and it has been very stressful dealing with this issue. I fear the dealership will disable the knock sensor so that it stops putting the engine on limp mode and then i will have a fire. I also fear that the knock sensor may not work correctly next time and the engine may catch fire. I need the engine fixed. I hope by submitting this complaint it will help get this engine problem solved for me and consumers.

What is Recall?
A recall is when a product is removed from the market or a correction is made to the product because it is either defective or potentially harmful.
What is Failure?
Failure is the state or condition of not meeting a desirable or intended objective, and may be viewed as the opposite of success. Product failure ranges from failure to sell the product to fracture of the product, in the worst cases leading to personal injury, the province of forensic engineering.
