Sorento LX

  • Automatic transmission
  • 82,993 miles

A D V E R T I S E M E N T S

Engine started knocking on 8/28/23. Had it towed to dealer on 8/29/23. Car has been sitting for 3 weeks now, while they say they submitted to KIA for engine replacement. They are telling me that it can take up to 8+ weeks to get approval, but no loaner or rental is provided. I am out of a car for at least two months and there is no care in the world to get it approved. KSDS update done in 2018 which did nothing. No check engine light came on.

Sorento LX 2.4L I4

  • Automatic transmission
  • 43,998 miles

2129 miles after Kia installed a new engine on my wife's car, she experienced decreased power and decreased acceleration, the check engine warning light came on. We drove it to the dealer. The technician made the repair, I think he said they had to upgrade the software on the computer regarding the knock sensor. The repair was made in less than 1 hour and there was no charge.

6527 miles since replacement of knock sensor harness and 11370 miles Kia installed a new engine - My wife experienced the same decreased power/decreased acceleration "limp mode" warning light on her way home from work. We took the car to the dealer and they replaced the knock sensor. The car was at the dealership for 5 days and we were given a loaner car to drive.

I am highly unsatisfied with Kia. Their vehicles are garbage and they only choose to right half the vehicles. I have a 2015 Kia Sorento sxl 3.3l v6 lambda II engine. They recalled the 2.4 l engines which have the exact same problem as mine. Engine failure, engine knock. I messaged Kia directly about it and they have not replied. They need to fix this problem immediately. I was quoted $12,000 for a used engine which is more than the car is worth.

Sorento LX

  • Automatic transmission
  • 119,800 miles

I bought my 2015 Kia Sorento in december 2020 and it broke down in april 2021. There were no warning lights, no engine light, no kind of warning whatsoever until I was merging onto the interstate and that's when it started knocking, leaving me and my kids stranded on the side of the road on easter sunday. When I took it to the Kia dealership to have the problem assessed, and having to contact them every time because they never kept me updated on the situation, they finally informed me that it was the knock sensor and the fix was a $7029.90 engine replacement since the sensor was not updated. And a phone call to the manufacturer resulted in them blaming me for not updating their records that I was the new owner of the car (which I've never had to do) so they could send me the service update bulletin on the sensor, and, therefore, they were not going to replace the engine at no cost to me.

So, back to dealing with the dealership. It took several weeks for them to tell me that I had to pay for the engine and taxes before they would even order it and it would take 8 weeks for them to get it in, then I would have to pay for labor and taxes on that, which would take a couple days to. By this time it had been almost 3 months and roughly $13,000 of my new house down payment money on a rental by the time I received all of this info. Which I tried to get by filing my claim with and sending all of my rental, towing, and purchase price of a crappy car to the kiaenginesettlement.com website just for them to deny me because they said I didn't submit the document for towing or a repair bill, when they in fact got a copy of my tow bill and and told them I had not gotten my car repaired yet because I was a single mom of 2 kids working a part time job and could not afford that expensive of a repair. (Which I couldn't until I got my portion of the settlement money, that I am now not going to.)

So, now, I am stuck with a $10,200.00 car payment for a car that can't be driven and now can't afford because I'm now unemployed with no unemployment compensation.

There should be a way to replace the connecting rod, that a non-Kia repair garage said it was, to the engine without having to replace the whole engine.

Which all of this just added to my already bad luck that I'd been having with trying to buy a new house. :'(

Sorento LX 2.4L I4

  • Automatic transmission
  • 46,712 miles

2714 miles since software upgrade on the knock sensor and 4843 miles since Kia installed a new engine - My wife experienced decreased power/decreased acceleration two months before on her way home from work. We know now that the car was in "limp mode". We took the car to the dealer and had to leave the car. It was later determined that the issue was due to the "knock sensor harness" and replacement was made, the repair was no charge. The car was at the dealer for 7 days.

Sorento LX 3.2L V6

  • Automatic transmission
  • 86,523 miles

I purchased my 2015 Kia Sorento in December of 2015. It is the first almost new car that I have ever owned, so I made sure I did all of the proper maintenance on time as I wanted to keep it nice and running good.

In Nov. of this year (2018) it started making a knocking noise in the engine. I work at a bus garage so I took it in to work and had the mechanic at work just listen to it and he said it sounds like an internal problem and not to drive it to much, so I haven't driven it since. I have not had it to a Kia dealer yet because I thought I would call Kia customer service first and see if it's covered under the recall. Yup you guessed it, it's not. So I asked them if I took it to a dealer and they found that it had the same problem, if it would then be covered and was told no. That the only way it would be covered is if Kia added my year, make, and model to the recall list and they wouldn't do that until they received so many calls about a problem.

When I purchased the car I also purchased the extended warranty so I am curious to see if it will be covered under the warranty. I will update when I find out. If I am told that it is not covered under the warranty I will be trying to contact the law firm that handled the case against Hyundai for the lawsuit filled against them for the 2011-2014 Sonata owners.

As far as I am concerned Kia needs to do what is right and fix these cars because obviously they have a problem that has nothing to do with improper maintenance.

Update from Apr 23, 2019: well I have better news than some … I took my car to the dealer after calling to see if it was still covered under warranty because they wouldn't cover it under the recall which I think they should have had to considering all of the problems they are having with Kia and Hyundai engines, any how after it was at the dealers for a week they called and said I needed to show proof of my 8 most recent oil changes receipts for proof that I maintained the car properly again I think it's crap considering all the cars under recall, but anyhow I had the last 8 receipts so I took them to the dealer and fast forward 2 weeks I have my car back it was fixed under the warranty, so I am very happy with the results I got, but I still think it should have been covered under the recall because the last I checked (about a month ago) I read were the recall is now 2.4 million under the recall and another 3.7 million that are going to get a safety device installed in them to alert the driver of engine trouble so that means between the ones under the recall and the ones that are going to receive the safety device their are over 6 million with either an engine problem or potential problem that is a huge amount
