I have a 2011 Hyundaii Tucson and I have been having issues with the ECO light it is not coming on in the same manner as before. When the ligh is off it feels as if my transmission is jerking
My car seems to shift hard when I accelerate and when I brake.. Any ideas
why this is happening.
Basic start.. Have it read for codes, even if the check engine light is NOT on the computer will have stored information and codes. Discount auto stores will read codes for no fee. write them down.
As Auto_Centric said have the Codes check, it could be the transmission speed sensor.
So I have had the check engine light read before and it said something about the transaxial temp. It is an automatic so the clutch isn't it.
with 4wd..always check the transfer case...at the very least see it it's hot when the resistance seems apparent~ ...and of course my usual answer is with a battery of your age...it's time to get a new one...old batteries do not hold up to drains over time...reduced voltages and errors appear...NEW batt~ and new connections...use a wirebrush to get to the metal so that 80 amps for your startermotor is readily available...perhaps the reduced voltage and lack of proper grounding to engine and frame brings on this condition....with a New battery and check those ground cables may solve your crisis~...and the xfer case to be checked~
Hi Rwyant01, I have the exact same issue with my car. Hyundai Tucson Limited 2011. Sometime when I drive, the ECO light goes off and then it shifts really badly when I accelerate or brake. It does this until the ECO light comes back. For some reason, only does it during the summer. Was your issue resolved? How did they fix it?
I too have the sample problem and it's very loud.
