Filed Feb 25, 2023 · Brakes, Driver assistance · TX

It all started on Thursday, February 16 when I went into my garage and noticed a strange chemical smell and my car battery was dead. My husband replaced the battery that night, but we noticed the break lights stayed on. When took it to a Firestone Department on Friday, February 17, they replaced the battery terminal and ran diagnostics. We finally called and got an answer on Monday, February 20. The mechanic said it was the ABS Control Module and wiring harness. We transported the car that Monday afternoon to the local Hyundai dealership, which we really didn’t want to deal with since we haven’t had nice experiences with them in the past. They never called us and when we finally got ahold of the service department on Wednesday, February 22, they stated that they believe that it is the ABS Control Module, but they are unable to fix it locally. We would have to send it to another Hyundai dealership which is about 100 miles away. After speaking to the Hyundai Corporate Office, they suggested with previous recalls to place an incident report. The recall for the ABS Systems for Hyundai came out on May 16, 2018 and the recall number 218. The recall includes cars with the cruise control systems.

When the cruise control shuts down, the tachometer cuts out and the vehicle seems to go into limp mode. Brightening or dimming the headlights causes an intermittent bright flash to the interior lights. This could be potentially dangerous seeing as you have no acceleration, which could cause very extensive damage to person and property. The intermittent bright flash could be a result of an unregulated power surge, which could cause damage to person and property.

Most recent incident took place 9.10.2014. I?m filing this complaint due to the safety concerns associated with the car accelerating when I?m intending for it to slow down by turning off the cruise control. I informed the dealership of this issue when I took my vehicle in for service and since it did not happen during a test drive they did not pursue the issue any further. The inability to duplicate the issue during a test drive does not reduce the safety impact of this software issue when the error occurs.
