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 fascinating predicament as his 2017 SUV consumes irregular quantities of oil. Here 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 mainly deny a brand new engine even when my oil consumption is over the restrict? I do know I went over the mileage a number of instances a minimum of, however nothing loopy like 5k over. I’ve by no means gotten any work finished on the vendor moreover a number of oil adjustments, 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 maintain topping off the oil each week till I find yourself getting a brand new automotive? Can this realistically final for a number of years if I maintain 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 beneficial oil change interval a few instances is not 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 inclined to issues associated to irregular oil adjustments, however finally, issues happen.
The NHTSA investigation
The 2017 Kia Sorento in query comes geared up 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 big variety of engines to develop irregular quantities of noise and to grab.
Over 1.7 million Hyundai and Kia autos are affected by this. Nonetheless, I’ve to offer credit score to Hyundai for issuing its newest mass recall that impacts over 1,000,000 autos, a few of which over 10 years previous. Then, there’s the problem of excessive oil consumption, which, from what I believe, is not being dealt with in the easiest way.
In line 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 might 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 couple of quart of oil attributable to a leaky entrance major 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 lowered 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 suppose they’d provide you with 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’d attempt a minimum of three or 4 4,000-mile oil adjustments with Valvoline Restore and Defend 5w30. It’s designed to wash up the engine and particularly the oil management rings, and should assist cut back your consumption. Been listening to fairly good opinions on it up to now. I’d attempt that earlier than dumping the automotive.”
Missingcurlybracket says: “It’s a Kia direct injection 2.4L, it may very effectively 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 response to the handbook’s extreme schedule which seemingly 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 vehicles, however not these.
Simply monitor oil degree, maintain receipts, hope for the very best.
There are others like coolant, brake fluid, trans fluid, rear diff/switch case in case you have an AWD, however the coupler itself is destined to finally fail and that’s a pair grand if you wish to maintain AWD. (@118k for me)
PCV valve change would possibly assist consumption.
I don’t hassle with the flowery oils personally except given a particular motive however value a shot.
Make sure the KSDS engine replace was utilized by the vendor previously for the guarantee on the underside finish.
And bear in mind, if you happen to do all the pieces proper, you would possibly nonetheless have to tug enamel on the vendor. There have been terrific and less-so experiences, so simply hope for the very best.”
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, might be utilized by the vendor as an excuse to not change 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 is just not unrealistic, it could be time to suppose 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 progressively being phased out in favor of the brand new Smartstream engines.
