Check Engine Light On problems of the 2008 Hyundai Entourage

My wife and I first brought our vehicle to columbia Hyundai/Acura in montgomery, ohio for a severe loss of power while she was driving. The incident nearly caused my wife and children to be rear-ended while trying to accelerate to highway speeds, which is 65 mph, here in the greater cincinnati area on interstate 275. Hyundai did warranty the work performed by their service shop at columbia Hyundai, but only after it was revealed to me that the Hyundai warranty only applied to the original owners. This was not something I was aware of and even the sales manager at jake sweeney used cars and I commented on how great this warranty was for me and my family because Hyundai stands by it. Well, they did not want to honor any of it until I illustrated that this was a defect in their vehicle and asking me to pay the costs of the repairs and associated repairs was ridiculous. The issue involved the cam phasers of the engine and were repaired along with other parts and a recall item addressed. Not less than one year ago, prior to my family and I going on vacation, we brought the van back for the same reason, although I did not notice any hesitations, the mechanic who test drove it did. It was the cam phasers once again. This time Hyundai only was willing to cover half of the repair costs, which left me with nearly $1,100 in total costs for a rental vehicle, fuel and the costs of parts and labor. This deeply affected our finances and nearly cancelled the vacation to florida I had been saving up for well over a year. Having no choice, I paid the costs, and took possession of the van after paying. I had not even left the dealership driveway when the check engine light came back on! my son was in the car with me and I have video of this occurring. The issue with the power loss happened again and still occurs today as recently as a few days ago with my wife & children in the van!.

Vehicle surges, the motor will rev up and down between 500 and 1400 rpms almost stalling. When stopped at a red light or stop sign with the vehicle in gear the van will surge and move you ahead 2-3 inches with the brakes applied. The vehicle will surge at different speeds with it in reverse with no one touching the gas pedal. The check engine light has never come on. The van also will act as if it has no power or not getting enough fuel when first taking off then it will take off like its got a turbo. Its tough to drive this vehicle safely and it doesn't do it all the time. Also had problems with shaking in the front at 65+ mph. Put new tires on and it helped but still does it. The sliding doors wont stay open on any inclines only on level ground. The brakes have pulsated/shake since about 10000 miles. Had metallic rattle coming from front tires when turning but only does it on occasion, usually when turning and backing up. The radio volume will sometimes lock and not turn up or down. It carries a 10 yr, 100,000 mile warranty and contacted dealer and Hyundai corporate office and are unwilling to replace any parts saying no code and can't duplicate problem for the surging.
