Description of the problem | In may 2014, while driving at about 40 mph, maybe 1200 rpm, my engine suddenly accelerated to 4500-5000 rpm, without a simultaneous rise in speed. A week or two later, the car did the same, under about the same conditions. The dealer could find no faults or codes, and could not duplicate the occurrence; not surprising since it was sporadic. The problem continued, with considerably more frequency; almost daily. Again i took it to the dealer in late july (mccafferty hyundai, langhorne, pa), and while a technician was driving with me, the engine raced again. They told me that there was a tech bulletin on this problem, and they would repair the car. The problem was in a module and needed recoding. At least that's what i thought they said. That repair seemed to cure the problem, until september, when a single occurrence happened. I though this was maybe a fluke, but the problem happened several more times in the following weeks. Today, 11/4/14, after several days in the dealer's shop, an insurance service tech said he could find no problem. I am now afraid to drive this car. While the car does not accelerate, maybe it's just a matter of time when the racing engine will cause severe acceleration and a subsequent accident. |
