Recalls and investigations

One recall on the transmission and drivetrain covers the 2015 model year. A recall on the same system isn't always the same failure, so read the defect text.

14V-784Dec 9, 2014
Power Train:Axle Assembly:Axle Shaft

Hyundai Motor America (Hyundai) is recalling certain 1.6 liter model year 2015 Sonata vehicles manufactured August 29, 2014, to October 28, 2014. The affected vehicles may have been assembled with an incorrect left axle shaft which may result in the shaft separating from the transaxle differential.

Risk and remedy
Risk: If the left axle shaft separates from the transaxle, the vehicle may stop moving, increasing the risk of a crash. Additionally, a separated axle shaft may allow the vehicle to roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.
Remedy: Hyundai will notify owners, dealers will inspect and replace the axle shaft, as necessary, free of charge. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 126.

When it happens

The middle half of failures fell between 16,000 and 69,000 miles, from the 28 reports that gave a mileage.

What owners wrote

“Multiple times, when the car start up and is put in to reverse, there is no throttle response. Simultaneously, it can not be put into the manual gear select mode and the car lurches into second gear.”

“The vehicle's transmission seems to be slipping or something. As you begin to come to a stop, the vehicle bogs down and you can not accelerate. There is a long hesitation and then suddenly it kicks in and jars the car. This happens on a daily basis. The vehicle is also burning through oil at an unprecedented rate.”

Should you keep driving it?

This page can't tell you that. 0 of 41 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
