| The vehicle's cruise control failed to engage or disengage when used. the dealership was initially unable to replicate the problem, then replaced a headlamp switch. after this, the radio began turning completely off while driving, and the cruise control continued to act erratically. the dealership said they could not replicate the problem but replaced the radio. several more times, the dealership stated they were unable to replicate the problem with the cruise control and radio. after contacting the manufacturer, the dealership looked at the car again and found loose pins in the connector to the fuse box. | |||

| My 2012 hyundai sonata turbo has the following persistent issue. when the vehicle sits over night, in cool weather conditions of about 60 degrees and/or lower, upon first start in the morning it will not rev past 4000 rpm (while driving) and as a result it doesn't have the power to merge onto the highway in a manner that i would consider safely. i know of a technical service bulletin that hyundai has released that's suppose to resolve this issue however, i also have knowledge of about 10 vehicles with this same issue, some the issue persisted even after the dealer claimed to have repaired it. what i consider the main safety issue to be is; there is no indication/alert within the vehicle's dashboard illustrating the issue affecting the acceleration/performance. my vehicle has normal power city streets or at about 30 mph or less. i discovered the issue when trying to merge onto a highway, due to lack of acceleration power (which my vehicle should/did have), i was nearly rear-ended by a 18 wheeler as i was trying to get up to highway speed. this is a huge safety issue. no check engine light has ever turned on. my vehicle has never been in an accident and has about 13,000 miles on it now. i would greatly appreciate your attention on this hazardous matter.

| I was driving down a hill that was not very steep, in good weather, with cruise control on at 60 mph. as the car went down the hill, the speed increased to 80,at which point in time i used my brake to slow down. the same thing has happened on numerous occasions with me alone and with others in the car, including a staff member of the dealership, who told me that this was normal behavior for a hyundai sonata and for the cruise control on his own vehicle. if i cancel cruise control in the middle of a hill, speed decreases or holds steady --it does not accelerate. *tr | |||

| Three problems cropped up immediately or shortly after initial ownership. the car pulls to the right, and the steering wheel must be turned to the left of center to compensate when driving on a flat surface. second, the sunroof area developed a loud creaking sound when the car is driven through a turn or over uneven road surface. third, and most alarmingly, the cruise control intermittently fails to disengage when the cancel button is pressed. it also intermittently fails to engage when the set button is pressed. if the cruise control has failed to disengage, tapping the brake or pressing the main on/off button will cause it to disengage. however, the confusion that comes from the cancel button failure may lead to an accident. the dealer cannot replicate the problem during a short test drive and refuses to replace or test the electronic modules. | |||
