What did they adjust in the rear? I was under the impression that there were no adjustments possible. Especially the rear toe.UPDATE: I brought my 2015 Elantra in for service last week and mentioned the issue of rough steering feel and hard to keep the vehicle in a straight line on the highway. Since my vehicle is under warranty they took it upon themselves to replace the intermediate steering column. The cost would have been $1,200 as per the work order I saw at the time but did not receive. I just drove it home as my wife is the primary driver but it seemed smoother than before. I'll ask my wife what she thinks. I was going to mention the lubing of the U-joints in the column. I assume this is a common issue if they had the part in stock already?
The next issue is the rear toe still being off but within spec EVEN after the dealer performed a 4 wheel alignment. I plan to get a second opinion on the alignment printout I have and explore the shims to correct the rear toe.
