Vehicle sat in driveway for one week while on cruise. The day of return the sonata caught on fire without any person touching the car for one week. Brother who's house it was at was woken by neighbors at 7sm. Home had minor damage, but it could of been bad if it was in someone's garage. Fire started in engine and console. Fire department could not find out a reason. Car was totaled. Had to rent a car to get home that was 2 hours away. Never had an issue with this vehicle in the 12 years I owned it.
The contact owns a 2009 Hyundai Sonata. The contact stated while attempting to open the front driver's side door, the outside door handle detached from the vehicle. The contact also stated that all four door handles had detached from the vehicle. The contact called the local dealer and made them aware of the failure. The vehicle was not repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 180,000.
The sunroof detached from the vehicle at highway speed. The sunroof was not open or otherwise in operation when it detached. A mechanic concluded that the adhesive holding the glass to the sun roof assembly failed. The sunroof assembly was completely intact after the incident and did not appear to be damaged.
Takata recall. Accident happened on a highway going 60 miles an hour. A deer came out of the ditch, missed the deer. My daughter swerved into the ditch and launched over a gravel road and did a nose dive into a bean field. Crashing the front end of the car. The car is totaled.
The drivers side interior door handle is made of artificial "chrome". A few days ago, I opened the door and got a severely lacerated finger which bled a lot. I wrote to Hyundai about my injury. They sympathized, but said the car was out of warranty. As my vehicle only has 31,186 miles on it and is housed in my garage, I did not expect to be injured by a defective door handle on a pristinely maintained vehicle. This is a known issue, as I have found hundreds of posts on the internet about injuries from this handle. NHTSA has previously issued a recall for earlier model Hyundai's with this same problem. Here is one of the many quotes that I found.... …
Hyundai Sonata 2009 red warning light for passenger seal belt stays lit even if no ones setting there or only a purse, or no one setting ther. So I have to put seal belt into lock even when no one setting there. So I have to fasten seat belt all the time. When driving car all the time have to keep it fastened. Also window electric switch on driver side most times doesn't function properly. Then deal sold me it a few months ago. I opened door cover to see if it was a switch problem & there was 2/12 inches of dried dirt in bottom of door panel. Dealer large one in san antonio,tx, at used lot say it is normal. I seem to think it might have been flooded in water he say no way it normal. Sure jokes on me now purchased as is dummy me, in limbo in tx. Car paint is starting to chip as well with deep open scratches weird every wash seems to make it worse looking.
Tl* the contact owns a 2009 Hyundai Sonata. While driving approximately 40 MPH, the steering wheel started to turn left and right independently and the traction control and electronic stability control warning indicators illuminated. The contact coasted the vehicle to the side of the road, but did not power off the engine. The contact slowly drove to an independent mechanic where it was diagnosed that the crossmember was corroded and the rear driver side wheel almost detached. The vehicle was towed to suresky Hyundai (2 hatfield ln, goshen, ny 10924, [phone]) where it was diagnosed that the crossmember was corroded and needed to be replaced. The vehicle was in the process of being repaired. The manufacturer was notified of the failure and provided a case number. The approximate failure mileage was 150,000.
As I tried to open my passenger front side door this morning I pulled the handle off. The portion of the handle that connects into the latch mechanism had snapped off in the door. I would just take it in and get it fixed, but this is the third time I have had this exact problem, having lost the passenger rear handle earlier this summer and the driver's front about a year and a half ago. I can only conclude there must be a distinct defect with the construction on the doors of this model, and searching around the internet I've found a handful of other people who have had the same issue with their sonatas.
