Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

CarComplaints.com Notes: The 2011 Sonata has a seriously defective engine that seizes without warning. It was awarded the dubious honor of being the first CarTalk / CarComplaints Turd of the Week in late September 2015.

A class action lawsuit was filed in May 2015 against Hyundai that claims the 2.4L Sonata engine is defective. More info here.

2011 Hyundai Sonata Owner Comments

My wife and I have a 2011 Hyundai Sonata turbo with 4500 miles that pulls to the left at all speeds and is much worse at highway speeds requiring constant pressure to keep the car going in a straight line. A recent trip of 2500 miles mostly on interstate 95 became very tiring after hours of constant steering wheel correction. The car has been into the selling dealer three times {alignment twice and subframe adjustment} to correct the issue but car still pulls to the left. I strongly feel that this condition is a safety concern and am not comfortable with my wife driving the car on the highway. I am bringing the car into the dealer next week again and am told there are many cars with this same defect and Hyundai has issued a campaign code 927 to fix the problem.

Car does not track properly and wanders to the left. Front suspension rattles when going over rough pavement slowly. Have taken vehicle to local Hyundai dealer 3 times to correct issue unsuccessfully.

Sonata

The contact owns a 2011 Hyundai Sonata. While driving approximately 60 mph, the vehicle began to pull to the right and left direction abnormally. The vehicle was taken to an authorized dealer six times for the identical failure. The repairs performed consisted of the front driver side strut replacement, tire rotation, tire balancing and alignment. The failure persisted and all four tires were replaced but to no avail. The vehicle was not further repaired. The failure mileage was 1,800 and the VIN was unavailable.

Sonata

Vehicle pulls hard left when accelerator is applied. Seems to go straight when no gas pedal applied. When applying more accelerator pedal, the more the car pulls to the left. Very hard to keep car straight. Dealer says it is normal for my car due to the fact that it is a turbo limited with a lot of torque. I test drove another limited Sonata turbo at another dealer the week prior to buying my car at this dealer and it did not have the same problem. It went straight as an arrow no matter how much accelerator pedal was applied. This has been going on since I took the car off the lot. I didn't think anything of it as the dealer said it was normal for a turbo vehicle. Again, the vehicle I test drove at another vehicle was the same turbo model and it drove straight as an arrow.
