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 the moment, doing what Toyota did some 20 years in the past, there are additionally recognized points that plague a few of the Korean fashions. One Kia Sorento proprietor finds himself in an fascinating 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 dropping oil, however I used to be questioning if I haven’t got rock strong 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 occasions at the very least, however nothing loopy like 5k over. I’ve by no means gotten any work executed on the supplier moreover a couple of oil modifications, so I doubt they will do it as a courtesy with out extra historical past there.
If Kia doesn’t present a brand new engine, is my finest 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 couple of years if I maintain including oil and ensure it by no means runs low/dry? Is there every other preventative upkeep I can do to maintain this going until 150-200k?”
I see an issue straight away in the proprietor’s description of the issue. Going 5,000 miles over the advisable oil change interval a few occasions 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 prone to issues associated to irregular oil modifications, however ultimately, 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 recognized to be very problematic, resulting from poor manufacturing, inflicting a major variety of engines to develop irregular quantities of noise and to grab.
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 one million automobiles, a few of which over 10 years outdated. Then, there may be the problem 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 endure restore. If the oil consumption is greater than 1 quart per 1,000 miles, the engine will likely 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 dropping a few quart of oil resulting from a leaky entrance most important seal and valve cowl gasket.
Turbo engines are likely to burn a bit extra by design, due to the turbocharger’s lubrication necessities and the very 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 might be too late at this level.
Rhysoul says: “I don’t assume they’d provide you with a brand new engine straight away, they’d do the oil consumption check first (you come again each 1000 miles 3 occasions) and if that fails, they’d attempt a high finish cleaner (fancy piston soak).
But when they deny all that, I’d attempt at the very least three or 4 4,000-mile oil modifications with Valvoline Restore and Defend 5w30. It’s designed to wash up the engine and particularly the oil management rings, and should assist scale back your consumption. Been listening to fairly good evaluations 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 might very nicely sh*t the mattress tomorrow as they’re recognized 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 wish 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 stage, maintain 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 ultimately 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 trouble with the flamboyant oils personally until given a selected purpose however price a shot.
Make sure the KSDS engine replace was utilized by the supplier 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 drag tooth on the supplier. There have been terrific and less-so experiences, so simply hope for the most effective.”
Last ideas
Whereas there isn’t any definitive proof that the oil-change intervals haven’t been religiously saved up with (except for the proprietor’s confession), any sludge buildup, discovered upon inspection, may very well be utilized by the supplier as an excuse to not change the engine. If we take the proprietor’s phrase as a right, it appears 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 objective is just not unrealistic, it might be time to assume for an engine overhaul or a substitute engine. Some variants of the Hyundai/Kia Theta engines are nonetheless in manufacturing, on some markets, however they’re regularly being phased out in favor of the brand new Smartstream engines.
When you’ve got the same expertise or any insights, I’d love to listen to about them within the remark part beneath, so we will present a extra informative article for future reference.
