#279 of 339 sonata transmission clunk downshift

I just had exactly same experience with my 2011 Sonata at 19,000 miles. Driving on the highway, I thought and it felt like I had suddenly hit something, jarred my head so bad my teeth hurt. I looked at the gauges and saw that I was running at close to 5000 rpm, not the usual 2000.
I pulled over, tried to put the car in park, neutral, reverse, used the manual shifter, nothing would get it to shift gears. The indicator by the shifter showed that the tranny was in drive, but it was clearly in 2nd gear. I drove another 10 miles, then turned the engine off. Waited 10 minutes and turned it back on and everything seemed fine, except my massive headache from the jolt. Very scary, thinking about trading it in.

Don't trade it in, file a report with the NTSHB they need to know about the lemons Hyundai is selling. From what I have neen reading, they are becoming unsafe to drive. I see a class action lawsuite may be coming to wake Hyundai up!!
I had my car back in again two weeks ago for the fourth time for the transmission and last night it started acting up again on the way back from a trip. So far it has been in the dealership oiver 10 times and it is barely 2 years old!
Just do a google on Hyundai Sonata's transmission problems and you will find out this is becoming very, very common.
I can not afford to keep bringing it back into the dealership as it cost me time off from work, lost money and lost time. And I am sure Hyundai hates having to pay for all the repeat repairs.
The unecessary costs having to keep bringing it back in so regularily is really adding to the cost of the car. I figure if you buy a Hyundai, add an additional 10% to the cost of the car for all the time and money you will spend bringing it back in for repairs. In my case my hyundai is costing me and additional $2,500.00.

if you do further research it is not just a Hyundai transmission problem-Honda, Acura, Toyota, etc have their fair share of problems. We owned a 03 sonata, bought new 11/02. It started with the transmission problem with less than 100 miles. The transmission was finally replaced at about 4,000 miles. We traded the sonata in Nov. 04 for a 05 elantra with manual transmission. We then traded the elantra in July '10 for a '11 sonata with manual transmission. The elantra had over 100,000 problem free miles. The sonata now has 25,000+ miles. We decided to avoid automatic transmission vehicles. I think the transmission supplier should be investigated.

My 2011 Sonata is unreliable – Major disappointment and total let down!
Here is the letter that I wrote to Hyundai that gives a summary of the issues that I have experienced with my 2011 Sonata.
Dear Sir or Madam,
I am writing you today to express my total dissatisfaction with my 2011 Hyundai Sonata Limited.
At the beginning of 2010, I was so excited to hear the rave reviews about the new 2011 Sonata and could not wait for it to hit the market. I loved the sleek and sporty styling, the excellent fuel economy and the added technology features that were to be available with the car. Once the cars hit the market, I was one of the first to buy one in my area.
I purchased the car on 2/20/10. Within 2 weeks of purchasing the car, the car would not start. It was finally determined that there was a faulty brake switch that caused the push to start button not to work.
Over the past 18 months, this same issue has occurred more times than I can count. My car will not start and I am inconvenienced and left looking at a beautiful car that will not function and is not meeting my basic needs. I have had my brake switch replaced 4 times and the problem continues to reoccur.
This is a major issue. One expects for his or her new car to start reliably. I have researched on the internet and I am not the only person having this issue.
Yesterday, 10/11/11, my car would not start again! I cannot keep this car if I cannot count on it to start. Once again, I will have to take it in to be serviced and be inconvenienced.
In addition to not starting, the driver side window is malfunctioning, the traction light will not go out, the xm radio works intermittently, and the low tire light will not go out even though I have had the tire pressure checked 3 times.
I see all of your commercials on TV expressing the pride that you take in your vehicles. What can you do to fix this issue? A new car should be reliable. My car is a total lemon! I was really expecting much more. Please contact me to discuss.

I have had exactly the same problems with my 2011 Sonata. It won't start. Have had brake sensor replaced. Also, a couple of times it started but there was no display where it usually tells you what gear it is in. I have also had a couple of times when it seemed like my driver's side window was not going to go back up! Wow, my garage/dealer acts like I am crazy but I am glad to know I am not crazy. I love the looks of the Sonata but I think a new car should start EVERY TIME! I have around 20K miles on it!

If you have had it in several times and they have not been able to fix it you are probably covered under the lemon law. They would then have to buy it back and compensate you. Check the laws in your state.
Also make sure to tell Hyundai what a piece of junk they have scammed you with, call their consumer affairs at (800) 633-5151.
If his creates a safety problem report it with the NHTSA, otherwise make sure you also file with the BBB

Wow! I bought a 2011 Sonata. I only have 5k on it. I bought it for the turbo and the power. If this is what I have to look forward to then I may as well trade it in on American products. If you have an issue with a preignition sound then take it to hyundai. It is the turbo actuator rod rattling around. Kind of makes your car sound like a piece of crap to anyone with their windows rolled down.I work as a diesel mechanic and know how turbos are suppose to act and sound. Hyundai will say the problem is normal due to extreme heat.
Well it does not get much hotter than Oklahoma summers of 105 plus and my self driving. I also keep getting recall after recall in the mail. I guess no one tests their products before producing them like General Motors in the 80's. I also have a 2006 Honda Accord which has posed no issues except a bad batch of batteries from the manufacturer.
The warranty is only as good as the manufacturer who produced the vehicle.
I may just trade this thing in after all and just wash my hands of it. I expected more from Hyundai. I actually expected it to be like my Honda.

That's not a very kind or helpful response to someone who has already purchased the vehicle and is dissatisfied. This isn't a Sonata Fan Forum - it's for members to express their experiences and opinions, regardless of whether they're positive or negative.

My message was 277, I took the Sonata to the dealer who was very helpful, they did the computer flash reset for the transmission (and washed the car), and I have had no further issues, and have put 1000 miles on since the service.
