After about 2k miles my rear hatch rattles over the slightest bumps. No its not the seatbealts. No its not junk under the floors. No its not the door panels. Yes I can visibly see the rear hatch moving when the car goes over bumps. This is absolutely BS for how much I paid for this car. Ive tried adjusting the adjustable bump stops, but that barely helps. Besides those bump stops are already loose with the rubber gasket falling off. This rear hatch engineering is trash. Hyundai dealers are acting like they dont hear it.. please comment if you have the same issue and if it was solved (if so how??)

Exactly on temps. Same here in Massachusetts. The problem was born as temperatures dropped 30 degrees. I bet when summer returns it goes away, but either way the the tape works great, however I used a knit type glove I cut up, no felt tape, the screwed in mount keeps in place.. Other than flat spots on my tires, which were replaced under warranty at 5K, and a little tweaking on the push to open function on charge door, My I5 has been awesome. Happy motoring and please any updates appreciated. I would have paid $$$$ to rid the rattle, lol.

Here's what I did, it works fine, long term ???? fingers crossed..
I had the hatch latch replaced as a warranty repair and the rattle totally vanished.

How much work was that for the dealership to complete? Did they troubleshoot the noise themselves?
They troubleshoot it for me (Foundation Hyundai in Boulder, CO), ordered the part, and replaced the latch in about a hour. Pretty simple to solve.
Hi BoulderMike,
I also have the rattle problem. It started about a month ago with about 4500 miles on the odometer (when it was warm out) . I did turn out the two bumper pieces which helped some. I have an appointment with the dealer but have to wait 6 weeks for the appointment 😤
I may try the tape in the meantime as the noise is really annoying. I don't notice it on the highway.
Would you mind posting the dealer repair order so I can see what part numbers they used for the fix. Might be helpful if they are not familiar with the problem to show them what worked.
Thanks
Sure. It was Part Number 818LO-GI100, Power Latch Assembly. I had the work done at Foundation Hyundai in Boulder, CO. It took about a week for the part to come in as they had to order it. Best of luck!
Great! Thank you.

I have had the same problem as I had posted earlier in this thread but what did it for me this week is that I greased the latch and have not had any noise so far. The washers and the foam tape on the bumpers didn't work. Let's hope this is the end of it and a cheap and easy solution.

Update after dealer appointment: It was not the washers it is the hatch mechanism. It was greased as suggested by one other and it did work. It has been 2 weeks and no rattle.

Where exactly (and how) was the grease applied? And, what kind of grease? Noob here!

Wow! This totally solved it! Thank you so much for sharing.I ended up wrapping the plastic bumper pieces using felt tape and that eliminated all the noise and rattling I was experiencing. Attached a photo. When the lid is closed, I can see that things feel much "tighter" when the tailgate locks itself, similar to what happens when you extend those bumper stops way too far out. I wrote in another post that unscrewing the rubber bumpers did not help with my problem. I'm glad that I've managed to make this go away because the rattle certainly made the ride feel quality feel really "cheap". Now it's quieter than a mouse.![Image]()

I have a n I 5 and the back has developed a rattle too. It sounds like Plastic on Plastic. I emptied my rear cargo area and it may have gotten worse. Hard to imagine. I did read on Redit that a number of other I 5 owners have the same issue. They tried felt pads on the adjustable lid bumpers and a piece of duct tape wrapped it around the latch receiver and they say it helped a lot. I'll let you know what I find. But this seems to be a regular issue with the I 5.
Any chance someone from Canada got the TSB for this fix? It seems like for the washer fix, hardly any dealerships have the parts and the parts are crazy back ordered.
I'm in Toronto GTA area, I couldn't find any dealerships with the parts readily available.

I took my SE in noticing right after I bought the car the rattle. They had it for a day-and-a-half and came back with: “it’s a body flex rattle” and can not be fixed. So frustrated that I have to live with this sound. Again, ridiculous amount of money I pd for this car and there is no fix.
There's a TSB on this with a fix. Lots of info on it throughout this forum and Google! For most, the fix solved the rattle. For others, they used a lubricant on the 2 rubber pieces in the closing area.
I added 4 washers from the spare nut/bolt/washer coffee can in the garage to the bump stops on the sides. Done Hatch closes tight. The intent is to move the bumpers out a little so the angled area of the hatch rests tighter against the bumpers
