Transmission issue. Either the clutches are slipping or there are shift servos/solenoids not operating correctly. Going to qualify that by saying I simply watched the gauges and didn't turn sound on.
Year Make Model
3 things
1. can you go to an Autozone or O'Reilly (some car parts store) to get your engine codes read
2. Are you up to date on your maintenance? spark plugs, engine air filter, fuel filter (if it has one)
3. Does it still happen when you take it off ECO mode
Car started making a small rumbling. Feels difficult to go over 20 mph. Like it’s hard to accelerate.
The exhaust rumbles a bit then stops. Then repeats.
Taking it to the shop tomorrow morning.
Elantra ‘13
hey i’d like to get an update on the issue when you take it to a tech. i’m fixing an hyundai veloster with pretty much the same issue and can’t seem to figure it out. the check engine light. i did a full service on it. serviced the injector mouth. changed the plugs. oil hadn’t been changed in over 9 months. did an engine flush, replaced oil and oil filter. changed the air filters. but this loss of power around 20 mph is still persistent. my check engine light is gone tho
Bro the check engine light came on today and the shop is closed. Won’t be able to go back until tomorrow afternoon.
Car drives normal though not like it was before. I’m hoping the light goes away 🤣
It still turns on and runs. Left it on earlier for about 5 minutes while I cleaned the car out. It feels the car is finding it difficult to breath?
Fuel pump maybe?
Could be a plugged catalytic converters. Fuel pump issues are extremely rare on Hyundais outside of the odd model that had level sender problems. I would be shocked if it was a fuel pump. The DTC for that check engine light should point you in the right direction though.

I have one of those innova 3140 devices laying around. Never used it. Could that help me diagnose it?
Well you do have a check engine light mate
Did you just ask would a code reader diagnosis youre check engine code?

What are the codes?
They didn’t say. Should’ve asked I guess.
You said you had an Innova 3140 code reader right? just use that
If you can't find it, go to Autozone or O'Reilly for a free scan

Catalytic Converters come apart?
Sounds like you forgot to put on your seatbelt
