Kia Cerato Engine Problems
Kia Cerato 2015: Ticking sound when engine starts
The clicking sound could be a sign of a weak battery, which is having difficulty coping with the cold weather. Don’t pump the accelerator; that does nothing on a fuel-injected car. Have the battery tested.
Loud tappet noise after servicing
The tappets are not adjustable, and it’s not normal that they are noisy. It’s hard to know what has happened as a result of it standing for so long. Have a mechanic check the tappets.
Kia Cerato engine pinging
It should run on 91-octane fuel without pinging; the knock sensor should ensure that it doesn't occur. Running it on higher-octane fuels makes it less prone to pinging, and again the knock sensor should have it running on the edge of pinging without actually doing it. I would keep the pressure on Kia to fix the problem, and at the same time get the help of an independent mechanic.
Cerato engine miss and broken speedometer
You could clean the throttle body to fix the miss. After that you should be looking at the electronics on the engine. The speedo is a mystery, but you would have to think that it is related to the car's electronics.
Cerato shakes after starting
The problem needs to sorted out with the dealer and Kia, so go back and tell the dealer you are unhappy with the car as it is and request them to fix it. Tell them you will not accept the car as it is. Ask them to demonstrate on another Cerato that the problem is 'normal'.
Mystery problem with Cerato Si?
Like you I doubt very much that changing to higher octane fuel will have any affect on the problem as you describe it. It seems likely that it’s a problem with the idle setting and that’s where they should be looking. Follow the dealer’s advice and run two fills of 95-octane fuel through it, so you can rule that out as a solution when you take it back. The only thing you can do is to keep the pressure up on the dealer, and to register your complaint directly with Kia’s customer assistance people.
2014 Kia Cerato intermittent vibration at idle
You need to have a mechanic observe the vibration first-hand and he might be able to diagnose it for you. It's impossible to diagnose without observing it. If you're really concerned about it take it back to the dealership where you bought it and try again to have them assess it for you.
Kia Cerato excessive lifter noise
It seems that Kia has changed from hydraulic to mechanical lash adjusters, which is the reason for the noise. They told us the change was made for better reliability and service life, and lower cost of servicing.
