general problems of the 2010 Hyundai Santa Fe

Driving approximately 70-75mph on highway with cruise control set. Car starts to make rattling sound & engine warning light goes on, car struggles to accelerate and hovers around 60mph. Upon inspection of engine oil in car, fresh oil has been burned up quickly! added 1 quart. Drove 45mins at 70-75mph. Notice engine light on again. Check engine oil. Had quickly burned through 1qt! add new quart of oil. Let car rest overnight. Driving 70mph without use of cruise control. Then use cruise control. After a bit car engine sounds of rattling & struggling to accelerate. Rpm gauge seen going up & down. Through rear view mirror I see lots of bluish smoke. Pull over to let engine rest. Check oil = still 3/4. Use engine dectection device. Indicates that cylinders 3 &4 misfiring. Reset car warning indicator with my detection device. Finish drive going 60mph to arrive at destination without car engine warning going back on.

Since purchased new in 2011, vehicle has stalled, losing power without warning in 6 separate incidents. Road surfaces were level and speeds ranged from 0-50 mph. During each malfunction, speed decreased to 0 mph or did not accelerate if already at 0 mph. Loss of speed is accompanied by presence of engine, battery, and oil indicator lights. I am able to shift from drive to park mode, completely turn off engine, and restart ignition. Vehicle appears to operate normally after each incident until next one occurs. All but two incidents occurred intermittently months apart on metropolitan interstate highways with heavy traffic conditions. Two most recent incidents occurred on same day within minutes of each other. Every time vehicle was taken to authorized dealer for evaluation, typically within hour of incident, technicians have been unable to duplicate problem or diagnose malfunction. Consequently, vehicle has not been repaired. According to 4 authorized dealers and Hyundai consumer affairs, trouble code is necessary to repair malfunction. Two authorized dealers have evaluated vehicle without diagnosing malfunction. Neither has been able to duplicate problem or find trouble code, despite maintaining possession of vehicle for days. Based on my history of complaints about same safety concern, however, techline advised authorized dealer to replace electric throttle control motor: procedure done in October 2013, yet stalling/loss of power occurred again--twice--in April 2014. Sporadically recurring malfunction remains unresolved. I have two separate cases filed with Hyundai consumer affairs. Vehicle is under warranty, up-to-date on maintenance, and has accumulated relatively low mileage to date at approximately 37,000 miles. **4/16/2014**stalled/lost power twice, 2-3 minutes between incidents. Towed to authorized dealer; currently awaiting instructions from techline.

Event has occurred on 2 occasions. First event: while backing up in a parking lot, with no foot on the brake, and very slight force on gas pedal, the car surged much more than typical with such a light contact with the gas pedal. The car accelerated backward suddenly, until the brake was applied shortly thereafter. Second event: while pulling into a parking spot at very low speed. The same event occurred, but this time while in forward drive. With no foot on the brake, and very slight force on gas pedal, the car surged much more than typical with such a light contact with the gas pedal. The car accelerated forward suddenly, until the brake was applied shortly thereafter.

2001 Hyundai Santa Fe lurches when gear is put to drive, or when driving at low or high speeds where it is worst (feeling that we just got rear ended). Started about 3 months ago. This happened before, about 3 to 4 years ago, and was diagnosed and have replaced the input/output speed control by the dealership. This seems to be a rampant problem that needs to be addressed soon because it is big safety issue.

Experienced a sudden jerking of Santa Fe 2010. During the past month or so, this problem had occurred few times while driving at a low speed during the warm up period. Car was brought in the Hyundai service department and is being investigated and repaired.

From stop,making left turn, lost all power momentarily, rpm dropped to idle. Pressing accelerator did nothing, finally engine came back and accelerated wildly. Very dangerous.
