Purchased TF Optima MY14 2.4l second hand in May 2016 with 42500km. Had a great run no problems until a slight tick developed and escalated to a big rattle/knock. Mechanic called it as big end failure at 130700km. Needs a rebuild or secondhand engine $6000. This is not good enough for a modern vehicle.
It is the third the mechanic has had with this 2.4l motor in the last few weeks. Appears to be a problem with this motor. If it was 6 months younger it would have still been in warranty.

Loads of power yet economical when you want it to be, roomy and comfortable, sensible and attractive interior layout, and superb ride with a good variety of Drive modes. Would have liken ventilated seats, but everything else is there. Would recommend to anyone wanting an all-around car.

This is our fifth KIA. My husband drives a Sportage SLi 2015 and I the Optima GT. The previous KIAs were two Rio's used for high milage, before we retired and a Cerato Koupe Touring. Todate no problems worth mentioning. What problems we have had have been fixed promptly. The GT is a joy, fast and reasonable frugal. Being a MY 2017 it comes with high beam assisted and LED head lights, both dip and main, fabulous. I will end here, for any more comments would also the lines of fabulous, excellent and similar

I have KIA optima for 4 years and have done 120,000 km. It still runs like brand new. Car regularly serviced at KIA dealer. Car service interval is short to 75,000 km, it should be at least 10,000 km.

September 2018: Engine Issues the Car wouldnt start, eventually when the vehicle was taken back to the dealer for inspection They couldnt find a fault, and explained it was an electrical issue and they are difficult to find.
September 2018: Dropping our son at school the vehicle locked itself with the keys in the car locking the youngest child in the vehicle for 15 minutes the car again locking and unlocking on its own and the mirrors were going in and out. Car key was reset and batteries changed - still have this issue to date

Hi Everyone
I previously wrote a review about my Kia Optima how happy my wife and I were with our Kia Optima at 153k's
Sadly since then I have had an engine failure on my Kia Optima bottom end engine noise, the 2.4 Engine had a recall checking Crankshaft bearing tolerances and there was a specific Vin number range that experienced a knocking noise in the Engine.
Unfortunately my Optima was not in that Vin number range,
I took the Optima to the Kia dealer at Mt.Gravatt who informed myself that they measured the tolerances and ga...

The Optima shares its platform, and many of its components, with its sister car: the Hyundai Sonata.

Targeted at other midsized sedans such as the Hyundai Sonata, Toyota Camry, Mazda6, Ford Mondeo, Skoda Octavia, and Holden Commodore, the Optima features a big boot and a comfortable ride.

A six-speed torque converted automatic is the only transmission for both the naturally-aspirated and turbocharged petrol engines.

Variants range from the base $33,390 Optima Si to the top-of-the-range $44,490 Optima GT NAV (BLACK LEATHER) SUNROOF.

Very reliable car and interior quality is better than German car. Very quiet and smooth ride. Turbo 2.0l is powerful enough. Have driven 80000 km and had not a single problem.

Bought my Optima Platinum from my employer. 4 yrs old and low Km's. Looks good and has lots of options being the top model. I use this car daily as a sales rep vehicle so I get to use it in all conditions. Handles well but I aim to get brighter headlight globes. Looks pretty sporty. Having a few issues with the dash computer, sometimes screen locks on something different or won't change. Reverse camera plays up sometimes. But I have not used the 7 yr warranty to get it looked at yet. Car runs well and is somewhat good economy, depending on wher...

We have a new Kia Optima n when it reaches 60km then drops to 57kms the car jolts by itself every time .kia tell us this is a "feature" does anyone else have this terrible feature in there optima . 4 times back to fix it n finally they come up with this answer

I bought this ex-lease car about 11 months from first registration. Was like new but at a much lower price. Very well equipped, drives well, feels well designed.Great having the 7 year warranty. The major downside is that this model misses out on any Satnav updates even though 2 were promised to new car buyers earlier, and it has many inaccuracies. Much better to use my portable TomTom with lifetime updates, and stuck to the windscreen.

Nice looking car specially when you compare with other cars in the same price range (used car).
BUT:
Almost all the options you see in the car are fake or low quality like cheap items you buy on EBay.
You may have different experience with your car but mine is exactly what I describe.
Stupid Sat Nav which doesn't recognize traffic in your way. I do prefer using Google Map on my phone. Much more trustable!!
It has speed camera warning which is not adjustable. It means you have 2 choices, ON with near 20 times alarm for each speed camera (a...

Great car, no problem at all. it has all the features, leather heated and cool seat, very reliable and had none fault. service interval 15000 km and very cheap around $200. Excellent handling. I love the panoramic roof.Better than German cars Audi and Bmw etc. I would recommend to everyone.

I bought my 2012 Kia Optima new and it has now done 102,000 klms and have had nothing done on it ,this car has been a pleasure to own and drive i sort of keep waiting for something to go wrong with it but never does,i would recommend this car to anyone out there looking at this type of car,the engine noise is a bit loud on take off but you get used to it and it has heaps of power as well.

What a fantastic car. Not only is it a pleasure to drive, but it has enough power to feel quite sporty. The only problem we have identified with these cars is their seats are incredibly uncomfortable, which unfortunately can be a limiting factor and almost caused us to sell it. Some wool seat covers fixed the problem and now we can take it on long drives (more than an hour) and not feel numb afterwards.

The Optima is probably the best handling car I have ever driven, although a little harsh on really rough roads. The interior is conservative, which I like, and all controls operate smoothly and positively. The car has given no problems at all and has been used for trips to Cairns and Melbourne, returning fuel consumption figures between 6.8 and 7.1 litres per 100 kilometres. Although a little noisy under acceleration, it is very quiet at highway speeds. The longer I own this car the better I like it.

This car has great handling, and was spacious for our kids. I love how quiet the car is. It did sit a little to low to the ground for my taste. The loved the safety alarms for seat belts and the auto air bag control using weight limit to turn on or off. Glad we rented this car while our car was down. I will be trading my car I'm soon for one of these.

First purchased a Kia Optima about 5 years ago due to it being best bang for your buck in terms of interior & features, & upgraded recently to the Optima turbo GT. Whilst it was a bit pricier, it has the quality of a much more expensive European car. Features such as adaptive cruise control, blind spot detection, parking sensors & camera, GPS, leather, the list goes on. At first I thought it was a bit tame, but once I found Sport mode I soon changed my mind, it really has some zip. The GPS isn't perfect (but show me one that is...), & some safety alert features need turning off before they drive you insane, but overall it is a very classy drive that has not failed to impress.

We love the performance of our OPTIMA as it does everything Kia claims. Mileage on a long trip comes in around 6ltrs per 100 ks driving to speed signage. It handles well but you do hear a lot of road noise especially if your tyres are too hard. The interior would be better if the leather was a light colour as black is a little hot for Australia and back seat passengers seem to have a problem putting on their seat belts. The reason we have not given five stars is the rust problem and the fact Kia will not honour their warranty. We have found areas on the body that wasn't even painted so unless you live in Central Australia you are going to experience rust. We love our OPTIMA but we just wish it didn’t have the rust problem.

We required to buy a new car and decided on another Kia. This time the Optima Platinum.
This vehicle not only looks great but performs and handles well. There is limited road noise and the standard tyres have a lot of grip. The car feels solid. Fuel economy is reasonable with a lot of city driving being 8.7 on Eco. Obviously on the highway it performs even better down around the 7.5.
Interior is sporty and comfortable with all the instrumentation easily readable. Even with my height there is still plenty of room for an adult behind the driver...
