I have been having phantom automatic transmission problems with occasional harsh shifting, mostly up shifting through all the gears but sometimes downshifting. This problem started in May 2014, lasted off and on for several days, and then stopped occurring. There had been a few instances of small drops of fluid on my carport but nothing consistent. Then in September, the problem started again on the same basis: on/off again, nothing consistent. When I couldn’t locate the port under the hood to check the transmission fluid, I took the Elantra to the Boise Hyundai dealership to ask where the trans fluid port was located. My service rep told me that there was no port in the new vehicles and that the transmission fluid was not changed until 100,000 miles at a cost of $400. The service technicians could not find anything wrong with the vehicle when they hooked it up to their computers to check the error codes, and the vehicles would not perform the harsh shifting when they test drove the car. The techs re-set the adaptive points and I was sent on my way. A few days later, the harsh shifting started again on and off, phantom problem. I took the Elantra back into the dealership and told them to keep it for as many days as it took for a tech to drive it home and start it cold in the morning. The transmission did not perform the harsh shifting for the 80 miles the tech drove it home and back to the dealership for three days.
After driving the Elantra another week, the phantom trans problems re-occurred and I was tearing my hair out. After surfing the web and checking the Hyundai Customer Forum, all I could find was problems with 2010 Elantra transmissions and my service tech admitted that Hyundai had replaced thousands of 2010 transmissions.
Through the dealership I opened a Case File for my transmission problems because there is something definitely wrong with the vehicle and I want a new transmission, and will press my case to the max. I’ve kept a log since September, noted daily temperatures, and times the trans has performed harsh shifting. I’ve kept the problem to a minimum by letting the car warm up for about 5 minutes and will only drive it when the tachometer needle rests on 1,000 rpms.
This week because I have major projects off my radar, I’ll begin driving the vehicle after only 1-2 minute warm up because somehow, it seems temperature of the trans fluid is playing into this problem. I’ll also take the Elantra into Hyundai to have the mileage certified for the annual debit card program that Hyundai issues to owners because of the erroneous in-town mileage advertised with the 2011 Hyundais. My service tech and I will also have a discussion where I want Hyundai to pull the trans pan to look at the fluid and have them waive the $400 charge. What stupid automotive engineers or corporate wallahs decided to eliminate a vital fluid check port in newer vehicles? To me, this is a No Brainer of a really bad idea!
Is there any other owner of a 2011 Hyundai Elantra who is having similar problems? I’ll also be surfing the Internet extensively again to see if there are similar entries on some web site with these phantom trans problems!
My dealership and Hyundai corporate both know I’d do anyting to have my 2001 Chevy Cavalier back in my possession with her 210,000 miles and a problem free car! My vehicles always have current service and maintenance so I haven’t been driving the Elantra and only filling the gas tank with no maintenance! Thanks for any input to this stupid problem!
