We got the recall notice on my girlfriend's 2002 Sonata as well, and I just took it in last Thurs.
Picked the car up at 5PM Friday (closing at 5:30), and as I put the car in reverse, the engine surged!!! Put it in park, and it surged up to 3k rpm!!!!!!! I immediately shut it off.
Went right in to get the service manager, who heard it himself after I rstarted the car. He grabbed the tech who did the job, who had me shut the car off and restart it again. Didn't surge this time.
Now I'm no novice to automotives, been a car guy since I could walk, and have worked on my own cars for years. Been in the auto parts business for years as an outside salesman, in and out of countless garages, talking with techs about drivibility issues. I've attended seminars for my customers, and know how systems basically operate.
I'm no dummy.
Tech checks the MAF sensor and tells me it's a cold start issue (which this car has NEVER had, she bought it new and has about 65k on it). I think it's total BS but tell the SM that I'll take it home and see how it goes. As soon as I pulled out of the yard, car is sounding funny, not running smoothly, and makes the damndest noise taking a right turn. No sense going back, the shop is closing and I can call him Monday if there's any problem, he said.
Called the SM today and he says he has no idea why the car is runnimg like that, maybe something was going wrong with the car before he got it. All they did was unplug the MAF, he said. Like I said, I know cars. I have no idea what steps Hyundai has them take to exchange the subframe, but I can't imagine it involves any engine management equipment on the upper part of the engine.
I told him that I wanted them to take a look at it, that the car was runing PERFECT when I brought it in, and asked that a different tech do the work, knowing that a different set of eyes might catch something the first tech screwed up. SM said no, the same guy would be doing the work.
Not how you get a good CS rating, that's for sure, which he was so concerned about when I picked up the car.
I'm going to see if I can bring the car to a different dealership, or possibly call the Zone Service manager in NJ, rather than let these guys fart around with it again.
Anyone ever hear of a car going in for this recall and coming out with drivibility problems?
