Driving on I95 and truck would suddenly only go 20, no faster. Thought I'd get killed with all the cars. Pulled off, waited and then restarted. It ran normal. Shortly after engine light come on. At Dealer, # 16 trip. Got call and they said that the code showed xxx problem and since having continual problems with truck they contacted engineer and decided too just clean/adjust. Are they crazy. Fix truck accordingly to code and quit screwing with me.

Update from Jul 17, 2026: Did it again, driving 55 and then down to 20mph, stayed like that awhile then speed back, then again, down to 20mph. For 80 miles until I got to dealer, it is at dealers now, engine light on, and yes 18 days at a dealer for repairs. Crazy dangerous. Car's honking, swerving and braking and we pray not to get hit and injured. Had truck 2 1/2 months and it was certified. Oh, so many issues> I have been working with HYUNDAI CORPORATE, HAVE CASE MANAGER, BBB AUTO, and anyone else I can complain too. So far NOTHING done. This is a CRITICAL SAFETY FAILURE, and they are putting our lives in danger every day. Something needs to be done ASAP. Contacting attorney
