Car seems to lose power and then jerks back on. Only lasts about 1 second. I purchased this car used with around 13000 miles. This has happened about 10 times during the 8 months I have owned the car. Dealer says without a trouble light/error code there is nothing they can do.
While driving at steady highway speeds, car experiences quick power surges. Visited dealership on two occasions now they tell me that they can not duplicate the problem, that their computers find no problem. Mechanic says " perhaps there is a part trying to go bad, but hasn't committed itself yet" what the hell does that mean? if you are just browsing this site, do not buy Hyundai!.
My car is 8 months old with 9300 miles, and I had to put another transmission in. . The Hyundai service manager claimed he put a new transmission in, when in fact he put a rebuilt transmission in. This happened 2 weeks ago. Then yesterday (04-13-04) my speedometer stopped working, brought it into the shop again, and was told they had to order a new speed sensor. What gives? don't they keep parts in stock. I phoned the parts department and asked if they had this sensor in stock and they said yes. I also called another dealer in the next town and was told they also had the part. So why did my dealer lie to me. .
About once a month I will be driving down the highway and the car jerks like it comes out of gear for a split second for no apparent reason. . It only happens above 55 mph or more.
