My curiosity concerning the expertise of fellow Hyundai and Kia homeowners prompted me to scout out the Kia Discussion board, and my newest discover didn’t disappoint. Whereas some would say that Hyundai and Kia are, at present, doing what Toyota did some 20 years in the past, there are additionally identified points that plague among the Korean fashions. One Kia Sorento proprietor finds himself in an attention-grabbing predicament as his 2017 SUV consumes irregular quantities of oil. This is what he says:
“I’ve a 2017 Sorento with the two.4L at 115kish miles. I used to be studying the TSB from Kia on the oil consumption and I’m could also be over their limits for how briskly it is shedding oil, however I used to be questioning if I haven’t got rock stable historical past of oil change, will Kia principally deny a brand new engine even when my oil consumption is over the restrict? I do know I went over the mileage a couple of instances no less than, however nothing loopy like 5k over. I’ve by no means gotten any work performed on the vendor moreover a couple of oil modifications, so I doubt they’re going to do it as a courtesy with out extra historical past there.
If Kia doesn’t present a brand new engine, is my greatest plan of action to simply hold topping off the oil each week till I find yourself getting a brand new automotive? Can this realistically final for a couple of years if I hold including oil and ensure it by no means runs low/dry? Is there another preventative upkeep I can do to maintain this going until 150-200k?”
I see an issue immediately in the proprietor’s description of the issue. Going 5,000 miles over the really helpful oil change interval a few instances isn’t any joke. In my expertise, whatever the engine or what the producer says, change the engine oil no later than 6,000 miles or 12 months. Sure, some engines are much less vulnerable to issues associated to irregular oil modifications, however finally, issues happen.
The NHTSA investigation
The 2017 Kia Sorento in query comes outfitted with a 2.4-liter gasoline engine from the Hyundai/Kia Theta engine household. All of those engines are identified to be very problematic, attributable to poor manufacturing, inflicting a major variety of engines to develop irregular quantities of noise and to grab. The Theta engine household has been burning a gap in Hyundai’s pockets and continues to plague even newer fashions.
Over 1.7 million Hyundai and Kia automobiles are affected by this. Nonetheless, I’ve to present credit score to Hyundai for issuing its newest mass recall that impacts over 1,000,000 automobiles, a few of which over 10 years previous. Then, there may be the difficulty of excessive oil consumption, which, from what I believe, is not being dealt with in the easiest way.
In accordance with the technical service bulletin, if the engine’s oil consumption is lower than 1 quart per 1,000 miles, the engine won’t bear restore. If the oil consumption is greater than 1 quart per 1,000 miles, the engine shall be topic to a restore.
In my expertise, a problem-free usually aspirated engine should not devour greater than a quart of oil per 6,000 miles. To place issues in perspective, the Lambda V-6 engine in my Hyundai Genesis Coupe was shedding a few quart of oil attributable to a leaky entrance foremost seal and valve cowl gasket.
Turbo engines are inclined to burn a bit extra by design, due to the turbocharger’s lubrication necessities and the actual fact these engines generate extra warmth. Additionally, turbo engines historically use thinner piston rings for decreased drag.
Some fellow discussion board members have chimed in with potential options to the issue, however it could be too late at this level.
Rhysoul says: “I don’t assume they’d offer you a brand new engine immediately, they’d do the oil consumption take a look at first (you come again each 1000 miles 3 instances) and if that fails, they’d attempt a prime finish cleaner (fancy piston soak).
But when they deny all that, I might attempt no less than three or 4 4,000-mile oil modifications with Valvoline Restore and Shield 5w30. It’s designed to scrub up the engine and particularly the oil management rings, and should assist cut back your consumption. Been listening to fairly good evaluations on it to date. I’d attempt that earlier than dumping the automotive.”
Missingcurlybracket says: “It’s a Kia direct injection 2.4L, it might very nicely sh*t the mattress tomorrow as they’re identified to do and it wouldn’t essentially be your fault in any respect.
What number of miles are we speaking anyway? 8000+ is pushing it. You’ll most likely need to do 3,750-mile intervals in accordance with the handbook’s extreme schedule which possible applies to you.
The handbook most likely says 7,500 usually, however don’t exceed 5,000 for this. you are able to do it in different automobiles, however not these.
Simply monitor oil degree, hold receipts, hope for the most effective.
There are others like coolant, brake fluid, trans fluid, rear diff/switch case when you have an AWD, however the coupler itself is destined to finally fail and that’s a pair grand if you wish to hold AWD. (@118k for me)
PCV valve change would possibly assist consumption.
I don’t hassle with the flowery oils personally until given a particular purpose however value a shot.
Make sure the KSDS engine replace was utilized by the vendor up to now for the guarantee on the underside finish.
And bear in mind, in case you do the whole lot proper, you would possibly nonetheless have to drag tooth on the vendor. There have been terrific and less-so experiences, so simply hope for the most effective.”
Remaining ideas
Whereas there is no such thing as a definitive proof that the oil-change intervals haven’t been religiously saved up with (other than the proprietor’s confession), any sludge buildup, discovered upon inspection, may very well be utilized by the vendor as an excuse to not substitute the engine. If we take the proprietor’s phrase without any consideration, it seems like the two.4-liter engine on this 2017 Sorento is consuming greater than a quart of oil per 1,000 miles.
Whereas the 150,000-mile aim will not be unrealistic, it could be time to assume for an engine overhaul or a alternative engine. Some variants of the Hyundai/Kia Theta engines are nonetheless in manufacturing, on some markets, however they’re steadily being phased out in favor of the brand new Smartstream engines.
