Piston Slap: The KSDS update, and the importance of a paper trail
I have a 2014 Hyundai Elantra Limited (VIN provided but redacted), and it seems to have developed piston slap. I’m having trouble finding out if this car is covered by the extended warranty or any other coverage to get it fixed. I’m wondering if you may know something more about it. Thanks for your time.
I checked your VIN on a Hyundai recall site and yours isn’t part of a formal recall for the engine. I am under the impression you have an extended warranty after performing the Knock Sensor Detection System update (KSDS), but nothing happens when I paste your VIN into that website. That’s why I always ask folks to check a local dealer to see if this can be done or was already performed.
Visit them when they aren’t busy (not early mornings, and not weekends) and forge a connection with the manager/director of service department, as he/she will help you if the motor fails. Even if our online VIN sleuthing comes up with nothing, these folks might be able to get you a new motor replacement under “goodwill” repairs. Sometimes all it takes is a friendly demeanor and proof of regular oil changes to start a paper trail in their system.
Thanks for the info Sajeev. I do have one more question. You said “proof of oil changes,” but once I purchased this car from my brother-in-law (who did get oil changes from the dealer), I started doing the oil changes myself at the same intervals as my in-law had done. So I don’t have proof of oil changes. Will it be a 100 percent no from Hyundai when they see I have no proof of my oil changes?
That’s a good question! It really depends on the aforementioned relationship you have with the dealership’s service manager, and what they tell the regional managers at Hyundai. You can go back to the dealership that did the oil changes for your brother-in-law; maybe they will be more motivated to help you, as that car has “supported” them in the past.
If you can pull up credit card receipts showing payment for oil changes (or oil and filters from a parts store), that might help prove your point. They can also do a little exploratory surgery inside the motor to determine if oil sludge is present, so there’s good reason to remain optimistic. While you will probably have to pay for that surgery, it’s totally worth the risk to get a new engine under warranty/goodwill.
In the end, the dealership and/or Hyundai’s regional manager will be your gatekeeper, and if they don’t see signs of neglect via paperwork or visual inspections, you might be good to go … should you need a new engine.
Thanks Sajeev, you have been a big help. I’ll be sure to let you know what happens. Thanks again.
