You know, of course, that accelerating a bit more aggressively would cause the transmission to stay in 3rd gear longer and as a result 4th gear would be engaged at a higher road speed/RPM. Off hand I would agree with the dealer that, given the fuel price situation and other economy concerns, the transmission is programmed to get into and stay in the highest gear (4th) as soon as possible for as long as possible. If you drive in a normal way or even try to "lightfoot" it more than normal the car will respond in the exact fashion you are complaining about. So, since I believe not only will you find all Hyundai's do this but most other manufacturers products as well it may be something you will either have to work around by driving a bit more aggressively or if you don't want to accelerate more briskly keep it in 3rd gear by using the Shiftronic feature until you reach a higher road speed (but this can also be accomplished by accelerating more briskly). This will reduce fuel economy so I guess you can't have it both ways. There is no "problem" with your transmission, the only problem is expecting the car to operate in too high a gear for the situation or low road speed. As an aside we own a 2006 Honda Civic with a 5 speed automatic transmission and to deliver the best fuel economy Honda has programmed this transmission to get into 5th gear ASAP (much like your Hyundai) and the result of that bit of programming is that the car downshifts at the mere sight of a rise in the road. Unless one is traveling at 65-70 mph the car downshifts on grade changes pretty readily....a problem? nope but it is an inconvenience.

For the record, several changes (actually thousands of changes) have been made to the Sonata since 2001 not the least of which are completely new engines attached to new transmissions and new fuel economy ratings with a completely new car wrapped aroud them. These new for 2007-08 EPA ratings now give what I believe to be pretty accurate numbers. I also think you will find the newest variant of the 4 cylinder is pretty quick (at least 90% of mid size car buyers will be happy) and the mileage WILL be much better than the V-6. The V-6 is a rocket but there is (as always) a price for performance..harder maintainence accessability and poorer fuel economy the first two on the list.

Dear Targettuning,
I understand what you saying about the fuel mileage vs. staying in 3rd gear longer (my 08 only has four gears) and realizethe trade off. However, do you think that 18 miles / gallon in short trips/in town driving is good? I get over 30 on the hwy, which I am pleased with but was hoping for better fuel efficiencty around town, especially if I have to put up with the lugging.

Refresh my memory as I forget if you have the 4 cylinder or the V-6 version. If you have the V-6 then, yes, I do think 18 mpg is good (at least not objectionable) for short trip/in town stop-go type driving. On the other hand it might be a bit low for the 4 cylinder but even then depending on the size of your town or city and how much more time you spend stopped than going this may be acceptable. For example I will refer back to our 2006 Civic EX sedan with 5 speed automatic...my wife drives this car for the most part and drives about 2 1/2 miles (if that) to work then putters around our largish town/smallish city accumulating maybe 15-20 miles per day and the last fill-up on Monday produced a little over 24 mpg. This is typical for this car in this driving scenario. Many would 'boo-hoo' such "low" fuel economy for a Honda (and a Civic yet) but I find it typically gets from about 21- 22 mpg in winter ( in Pa snow and cold) to about 25 max in summer using the A.C. This same car got 38+ mpg on our last road trip. I guess what I am trying to point out is that for a gas vehicle the absolute worst fuel economy is derived in the city...short trip...stop-go...gridlock type environment during which it frequently gets ZERO mpg. The only types of vehicles that shine in around town driving are 1. electric (of which there are few/none..yet) maybe diesel (of which there are few available), and for sure hybrids, especially the Toyota Prius/Toyota Camry hybrid.

please you all wrong about the Gears. Hyundai Sonata 2008 has 5 gears and not 4. only when you put it as stick shift you will see it as 4 but the automat has 5.

hello...I just found out my car is going to cost $900 to be fixed for what sounds like a common problem. The transmission slams into gear sporadically and drags after that. They say it is the output speed sensor. I'm finding the info on here very interesting and helpful. Can you let me know what you find out from the BBB and Hyundai on Friday ??? I would really appreciate it as the people at Hyundai were less than helpful. This car was serviced for this problem before and supposedly fixed. Thanks again

For 2008, in the U.S., the Sonata had four forward "gears" in the AT with the 2.4L engine, and five forward gears in the V6. For model year 2009, the Sonata 2.4L got a 5-speed automatic.

sorry but you still wrong they just didn't update it on the system. you can check it yourself. put the gear on manuele and then when its get to 4 switch it to auto you will hear the gear switch. also the Thecnitian confirmed that issue. thats why the transmittion has problems in the car.
