I just moved to Denver - after about a month (one week after a cold freeze) I noticed a slight whine when the transmission is in third (approx 2300 rpm) between 38 and 42 mph. It seems to disappear immediately on shifting to 4th. I do not hear it when the transmission downshifts. I might also mention that I lived in San Diego, and, at 30000 miles had the transmission fluid changed as part of the 30000 mile checkup. I do not believe they used Hyundai fluid. This was a AAA aproved repair shop and they provided documentation that said that the transmission fluid they used was OK for the vehicle.

Replying to: targettuning (Nov 02, 2007 6:53 am) Life ATF which is supposed to be consistent with SP-III. I have a signed letter from Valvoline which states that use of the fluid WILL NOT INVALIDATE the Warranty and it also lists all the vehicles that it is recommended for - which includes KIA SP-II and SP-III and Hyundai. Although I voiced some concern about this - I was assured by a reputable AAA repair shop (SAMCO in San Diego) that I was OK to use the Valvoline transmission fluid.

I just bought an '08 Sonata in November, 2007. Right away I noticed a definate shutter when driving around 40mph, just prior to shifting to 4th. It will remain as long as I stay at that speed. I took it in to be checked twice. 1st time tech didn't find it, 2nd time there was a TSB, and the transmission was reprogrammed. THAT was yesterday. On the way home, sure enough, it did it again, and again. Any suggestions? Thanks!

I recently purchased a the 08 Sonata, my very first car. Within 200 miles I noticed the shutter at or around 40 mph. I have taken the vehicle to the dealer more than three times,and have finally been assigned a "case number" with the manufacture. I do not like, and refuse to accept this malfunction.... Does anyone have any suggestions or advice on what I can do?? I have been advised that there is no solution and this is a known issue with this vehicle. ...disappointed |

Replying to: toshas (Jan 04, 2008 8:58 pm) http://www.hyundai-forums.com/index.php?showtopic=6559 Another with the same problem: http://www.hyundai-forums.com/index.php?showtopic=19223 All (5 or 6) similar models i have tried here in denmark had the exact same problem, and the danish importers technical manager, who also drives a V6 has the same problem, and finally accepted that there is problem that apparently cant be resolved. And i must say that, as far as i know, all have been tried from here. An A/T specialist even tried to deactivate the torque converter lockup by bypassing the brake-switch, but it didnt bring us closer to a solution (same shudder or even worse). Status for now when my cars has approx 52000 km on the odo: Get the tires optimally dynamically balanced (Hunter), and the vibration can be minimized (I have at least experienced that high tyre RFV (Radial force variation) and out-of-round can intesify the problem) The more perfect tire - the less wobble/shudder/vibration - But even with the most perfect tyre, as the set i have now where the RFV on all four tyre is below 2 kg, i still got a slight vibration. (Michelin PA3 winther) The point now is, that if i not have had all these problems from the start, and really got attention to it, then i guess i wouldnt have noticed it today. With my last set of tyres it's hardly noticable. I just hope that all my complains in the last 2½ year has been noticed by Hyundai and hopefylly has been resolved in the facelift... I'm really looking forward to try it when it arrives to Denmark in the 2. quarter of 2008. If it is solved - i will definately change... In all other areas - i think the car is perfect, and i wont hesitate to buy one again. |
