I'm the owner 3 of them: KIA Carnival 2000, KIA Carnival II 2002, and Naza Ria Se 2006. All of them I've driven over 150,000 km.

The most important thing is the engine cooling system, I've been modified them by joining the air conditioner condenser fan with the radiator fan, so they are running/working together, even if the air conditioning is off, as follows as the standard top heat timing (with professional wiring).

So that immediately made the engine cooler, and made the air conditioning more cool and faster air conditioning compressor cut off, (for a vehicle with heater, I've also removed the heater system and added the air conditioner thermostat for adjust temperature level, and made a faster air conditioner compressor cut off). That caused engine to not work so hard to avoid over heating problems, and also better oil consumption.

Hi to all RIA Owners.

Reference to the comment dated 27th Sep 2008 08:36.

Rather having the engine overhaul and without guarantee that it might not recur, heard also Nissan Cefiro 2.0 engine had been used as replacement.

Have a check you guys, it could be a positive move.

I need a contact on where to do the engine overhaul with the cheapest cost. Someone quoted me around RM6-7k. I'm broke, but still need to repair my Naza Ria

I am one of Ria-Family Club members, residing in N9. We N9 members prefer to send our Rias to one trustworthy workshop in Seremban 2 area. Even members from Johor & KL also sent their Rias here. I think you can appreciate the reasonable price that the workshop can offer. Unfortunately only one Ria can be majorly serviced within a day which is on Saturday (like changing of timing belt that only costs 1/2 the price than what SC charges). Overhauled? I think it might take a week or so...

Hi, I have a 2004 Ria and it has clocked about 70000km. Recently I was told by an ex Naza mechanic that a solution to the "teh tarik" problem has been found. He said something like placing "oil ring" or something. However, it will cost about 3k if all parts are reusable. Have any of you heard this one?

I bought my Naza Ria in 2005, and my Naza Ria also has the same problem. My car overheated last year, and it cost me RM5,000 to repair it. I thought the problem is solved and over. Nevertheless, it only last for about a year.

Last month, it happened again. The engine occasionally overheated due to low level of water/coolant in the radiator. I need to replenish the water/coolant every 2 or 3 days.

When I sent it to NAZA SC, they said that the water is entered into engine and the engine require overhaul due to leaking. NAZA SC estimate the repair cost is about RM13,000 and the cheapest way to overcome the problem is to modify the piston, it costs RM8,000, but no guarantee that the problem solve permanently.

I wonder why NAZA/KIA never stand up and admit the engineering problem in this car. Many Naza Ria owners faced the same problem, but NAZA/KIA never bother. I feel cheated by NAZA/KIA.

This is my last NAZA/KIA car and I would never buy NAZA/KIA brand in the future, and I would never recommend it to others even though the car is very comfortable.

Lastly, is there any option for us to bring up the matter because I feel that NAZA/KIA should be responsible for engineering failure? I would accept the cost of maintain the car if it due to wear and tear, but this is an engineering problem.

I was thinking to get the Naza Ria RS, which is currently on promotion by Naza at RM63k OTR.

But after reading this site, I found a lot of Naza owners having engine overheating problems, and it will cost a BOMB to repair it and made me step back.

Hope that Naza can fix this engine overheating problem ASAP.

I was about to buy the RIA at the offer price at RM63250. But than I asked the manager (a friend of mine) he say they are clearing stock for RIA and will bring in new models at next year. So I did not buy. But now I see so many problem in the car, I've lost my trust in NAZA. Will try look for Serina.

The lucky guy who ask...

We are the proud owner of reg. no. Naza, bought in 2005. In 2007 (my rough reminisce) we encountered overheating and sent it to Naza Selayang for engine replacement since it was under warranty.

But recently at around 72,000 km clocking, our Naza Ria with that new engine, we faced the similar problem which "nightmarish" to us back then, "overheating". We send it to a nearby workshop and were told that its radiator needed to be serviced and we ended up replacing the thermostat at a reasonable cost with labor.

But yesterday (15/08/09) I found the reserved water tank's water seriously diminishing to below LOW LEVEL, even though I made the effort to top it up several times after the first faulty temperature discovery and parts-changed and servicing on 30th July 2009.

To make it worst the mechanic opened the engine oil cap in front of my naked eyes and I saw the cap started to accumulate a "milky" sediments. "Astagharafirullah!" I jolted surprisingly. And the mechanic remarked "it's a sign of an engine problem".

We are all in the state of trauma since browsing the net on all matters and comments with regards to Naza Ria. I told my wife to stop driving her lovely Naza (which is leather, spacious - comfort, luxurious elements of MPV, kind of partly-6-children's pride") temporarily for her daily teaching vocation until we resolve the unwelcome alien before it becomes monster.

To Naza, is the policy of replacement remained considering the replacement record at your system apparently showed ours was a newly-changed engine and please advice us what shall we do to this seemed to be a "major setback" to our lovely machine?. Can we trade-in for another new Naza Ria (since we are the supporter of National-made, national-type industry) with your nearest showroom without much hassle and obligations.

Thank you.

I'm planning to buy a secondhand Naza Ria SE 2005 with 25000 mileage and very good condition... no scratch at all... hardly driven by the owner.. full accessories... he offer me RM78000 Sabah plate.. but after reading all the comments... it seems I have second thoughts of buying it... please advise my fellow friends.

Don't buy a NAZA Ria. It is not built to last! You think it's cheap now? It will burn a big hole in every owner's pocket.

I bought Naza Ria in 2004, and now the mileage is 90K, I encountered an abnormal sound before my car temp gauge showing high more than half, then I stopped the car too cool down, I checked the reservoir coolant water is full by hot water. My mechanic topped-up the water to the radiator. My car now is OK and the temperature gauge is back to the normal. Recently I encountered that my reservoir coolant level always decreases to the low level, even though I always top-up water every 3-4 day. Is it normal, or that is sign that the engine is having problems?
