Hyundai has announced a recall of the 2016 Hyundai Tucson to fix a software problem that could disable acceleration. The recall affects 41,000 vehicles registered in the U.S.
Documents from the National Highway Traffic Safety Administration say that the issue is rooted in the Tucson's transmission control module, which was supplied by Dymos Incorporated. As you might expect, that component controls gear-shifting on the Tucson's seven-speed, dual-clutch transmission. Unfortunately, warm weather seems to cause malfunctions in the module's software:
"In higher ambient temperatures and specific operating conditions, the transmission clutch application logic can result in a delayed engagement when accelerating from a stop. If the accelerator pedal is steadily depressed for approximately 1.5 to 2 seconds, the vehicle will begin to accelerate and normal driving is resumed. However, if the accelerator pedal is repeatedly cycled, the vehicle will not accelerate."
Should the software disable acceleration while the Tucson is in traffic, it could dramatically increase the risk of an accident. Thankfully, Hyundai knows of no collisions or injuries linked to the problem.
The recall affects 2016 Tucson vehicles built between May 20, 2015 and May 31, 2016 that came equipped with a seven-speed EcoShift Dual Clutch Transmission. Hyundai will mail recall notices to the owners of those vehicles by October 28, asking them to schedule service appointments at their local dealerships. Dealers will update the transmission control module software at no charge.
If you believe that you own one of these vehicles and have further questions, you're encouraged to call Hyundai customer service at 1-855-371-9460 and ask about recall #149. You can also call NHTSA's Vehicle Safety Hotline at 1-888-327-4236 and ask about safety campaign #16V628000.
