i WAS DRIVING ON MY WAY TO A DOCTOR'S APPOINTMENT, AND WHEN I REACHED A SPEED OF 55 MPH, THERE WAS A LOUD WHINING SOUND COMING FROM THE REAR. I HAD TO SLOW DOWN BELOW 55, SO THE NOISE WOULD GO AWAY, AND IT SCARED ME. WHILE DRIVING THE CAR, I COULD HEAR SOUNDS FROM THE REAR WHILE MAKING SLOW TURNS AROUND THE NEIGHBORHOOD. BEFORE BUYING THE CAR, I HAD A PAID INSPECTION, THE MECHANIC OBSERVED AN OIL DRIP FROM AROUND THE DIFFERENTIAL. THE CAR ONLY HAD 4000 MILES WHEN I BOUGHT IT. THE OWNER SAID SHE HAD TAKEN IT IN FOR A RECALL- #07204 - ON THE REAR DIFFERENTIAL AND HAD THE REAR PINION SEAL REPLACED. MY MECHANIC SAID THE REAR DIFFERENTIAL IS LEAKING OIL CAUSING THE DIFFERENTIAL NOISES. HE DRAINED THE DIFF OIL ADDING NEW OIL.($175) IT APPEARS THAT THE RECALL REPAIR HAS FAILED TO FIX THE DIFFERENTIAL OIL LEAK. THE SELLER HAS THE ORIGINAL #07204 RECEIPT FROM THE RECALL REPAIR. THE MILEAGE WAS 1,483. I PURCHASED THE CAR WITH 4,100 MILES- I ONLY DROVE IT FOR 1900 MILES. THE CAR NOW HAS 6,000 MILES ON IT. THE RECALL STATES If the vehicle is not repaired and damage progresses, three conditions can occur: (1) When the vehicle is stopped and shifted to reverse, the differential may jam and prevent vehicle movement; (2) the damage can cause drag that will feel like the brake is applied; or (3) the differential could jam and lock the drive wheels while the vehicle is in motion. If(3) occurs, the driver may not be able to control the vehicle and a crash could occur without warning. I AM CONVINCED THAT WITH THE LOW MILES, THE ORIGINAL RECALL HAD FAILED TO FIX THE REAR DIFFERENTIAL OIL LEAK. IT CONTINUES TO LEAK. I AM AFRAID TO DRIVE THIS CAR. IT IS A BEAUTIFUL 2007 SILVER SATURN SKY, 6000 MILES. I AM 78 Y.O.& RETIRED. SINCE THE 1ST RECALL FAILED TO FIX THE PROBLEM, COULD A FOLLOW-UP REMEDY RECALL BE HONORED TO ME SO THAT I COULD DRIVE MY CAR SAFELY? THANK YOU VERY KINDLY!

I purchased a used Saturn Sky 2007 vehicle. July 26th 2016. I noticed immediately the same day as a matter of fact a noise from the back end. I took care back a and they put grease in diferential.. but after a few days it was worse than ever. I purchased the extended warranty plan. After they tried looking at my car. I called my warranty company and ask if they could recommend a service center to take my car to have it serviced. Which I then proceeded to do. And my vehicle is still there. They sent a used diferential that was bad. I asked the warranty representative at that time to send me a new one which my contract states clearly I can have. But once again they sent another bad used one. And then another. Along with two others that were never delivered. And I've been offered a rental for 8 days total. And it is now Oct 18th.2016. I have no car. GM has this part now on national back order. And does not know when a part will be available. I attempted to contact different machine shops to see if it can be rebuilt they have tried to find parts to rebuild it there are none. I feel I have done everything possible to fix this vehicle. And it's a lemon.

Sometimes the passenger airbag does not turn on when there is an adult person seated in the seat. Also has an oil leak at the differential.

Was on interstate 97 in Maryland doing around 65 mph. When I heard and felt loud pop noise from the rear of the 2007 Saturn Sky and pulled onto the side of the highway while the cars on the road were flying by me at a high rate of speed ( that I was scared to get out of the car ) did get the car home and contacted Saturn ( what a waste of time ) to try and get some type of help on the repair. Took car to the local dealer jba Chevrolet and was told that the rear differential had blown out and the repair could be between $2800-$3500. I have seen on the web sites that this is a common problem with this type of rear in Saturn and other GM cars. I'm lucky that the rear did not lock up this could of been a big problem. Please pass this on.

I delivered the vehicle to bill fox Chevy for servicing as directed by GM (Saturn) customer service case number [xxx] for grinding noise and fluid leaking on the 2007 Saturn Sky (21433 miles). There was a recall ( 07V58900) for a faulty seal on this models differential unit. It showed the recall was handled on April 29,2008 by lakeside of Saturn which I did not recall. After investigation by the dealer it was agreed that the differential was grinding and the left differential/axle seal was leaking fluid. The repairs were made and had to pay $ $455.63 for the repairs on this defective designed part. GM denied my request for covering this under the recall notice. This is my wife's vehicle only driven in the summer. She did not know there was an issue. I drove it and noticed right away and found the recall and contacted GM(Saturn) cs. I stopped my wife from driving because the recall stated the differential could lockup and cause an accident which is a huge safety issue. Also I had a 100K warranty on the drivetrain which they said hit 5 yrs in August 2012. I believe GM should be held responsible for this recall on the total differential ext/int parts.

After I parked my Saturn Sky in my daughter-in-law's driveway for approximately 15 minutes, my son-in-law and I heard a loud "pop" from my Saturn Sky. About 5 minutes later, my Saturn Sky drifted backwards out of the driveway (slight downhill direction) and into the street. My son-in-law ran after the car and caught up to it just as stopped drifting backwards uphill in the street and began drifting forward in a downhill direction. He was able to reach into the car (the convertible top was down) and set the emergency brake. While doing so, the car ran over his foot injuring his toe. Thank god there were no children playing in the driveway! the emergency brake was initially set since the driveway does have a slight slope towards the street, but after cooling down for approximately 15 minutes, the emergency brake released.

The limited slip differential failed on my 2007 Saturn Sky. The failure of this component caused the car to suddenly and violently fishtail while making a left turn at normal highway speeds. The car subsequently smashed into the center median, then bounced into the adjacent lane where it collided with a large SUV. The SUV rolled over my hood and flipped over on its top. Fortunately no one was injured. The accident resulted in the SUV being totaled and severe front end damage to my car. The failure in the differential was first detected by the body repair technician and later verified by a qualified GM dealer. It is now being replaced under warranty. Condition: Weather was sunny and clear. No oil or water on the roadway. Safety recall NHTSA 07V589000, power train axle assembly axle shaft seal, was performed approximately 6 months earlier.
