Hyundai Atoz Common Problems and Solutions
Car jerking/cutting out
If you are having problems with the car jerking forward and/or the engine cutting out, the usual cause is a faulty MAP sensor.
Fitting a replacement MAP sensor should resolve the issue.
The ignition coils are known to fail on the Atoz. If you are having problems with the engine misfiring and/or the engine management warning light has appeared on the dashboard, this would be the most likely cause.
You will need to replace the ignition coils to fix this problem. It is recommended that you change them all at once for optimum performance. Have a look at the video below for an idea how to change a coil:
Cylinder head gasket failure
If you are noticing that the car is overheating, it could be caused by a blown cylinder head gasket. Ways of checking if it is the cylinder head gasket that has blown are: a white creamy substance when you open the oil filler cap and/or a mixture of oil and water in the water reservoir. If the car is overheating and you catch it early enough, it could just mean replacing the water pump. This issue is mentioned above.
Replacing the cylinder head gasket can be a big job, but this is what needs done to sort this issue.
Water pump failure
The water pump on the Atoz is prone to failure. This issue leads to overheating and if it is not seen to quickly enough, it can lead to cylinder head gasket failure. We have listed this cylinder head gasket failure below.
You will need to fit a replacement water pump to fix this problem. We can help you find a replacement water pump at a very low price.
