I did a little search on the NHTSA site and found they have finished their investigation. I guess they didn't see fit to notify anyone that complained to them about the car. You can read the findings at; http://www-odi.nhtsa.dot.gov/cars/problems/defect/results.cfm Guess we all need to get our cars down to the dealer for some adjustments. Saturn apparently is going to notify us but they're taking their sweet A$$ time doing it. WW

Sorry, the link won't connect. I've pasted the report below. NHTSA Action Number: NHTSA Recall Campaign Number: PE08016 N/A Make: SATURN Model: SKY Manufacturer : GENERAL MOTORS CORP. Year : 2008 Component : SERVICE BRAKES, HYDRAULIC:POWER ASSIST:VACUUM SERVICE BRAKES, HYDRAULIC:POWER ASSIST:HYDRAULIC SERVICE BRAKES, HYDRAULIC:ANTILOCK:CONTROL UNIT/MODULE Date Investigation Opened : March 6, 2008 Date Investigation Closed : June 24, 2008 Summary: IN MODEL YEAR (MY) 2007, PONTIAC SOLSTICE AND SATURN SKY VEHICLES EQUIPPED WITH THE 2.0L TURBOCHARGED ENGINE USED AN AUXILIARY VACUUM PUMP TO SUPPLEMENT THE ENGINE AS A SOURCE OF VACUUM TO THE BRAKE BOOSTER DURING LOW VACUUM CONDITIONS, SUCH AS IMMEDIATELY AFTER A COLD START. THE VACUUM PUMP OPERATION WAS CONTROLLED BY SWITCHES THAT SENSED BOOSTER VACUUM, TURNING THE PUMP ON WHEN BOOSTER VACUUM DROPPED BELOW A SPECIFIED LEVEL. IN THE MY 2008 SOLSTICE AND SKY VEHICLES (THE SUBJECT VEHICLES), GENERAL MOTORS (GM) ELIMINATED THE AUXILIARY VACUUM PUMP AND REPLACED IT WITH THE OPTIMIZED HYDRAULIC BRAKING (OHB) SYSTEM. THE DESIGN INTENT OF OHB IS TO SUPPLEMENT ENGINE VACUUM, IN CONDITIONS WHERE LOW VACUUM IS GENERATED BY THE ENGINE, WITH HYDRAULIC PRESSURE GENERATED BY THE STABILITY CONTROL SYSTEM PUMP CONTROLLED BY THE ELECTRONIC BRAKE CONTROL MODULE (EBCM). FOR UP TO ABOUT A MINUTE AFTER A COLD START, WHEN THE SYSTEM IS IN OHB ASSIST MODE, THE DRIVER MUST PRESS HARDER ON THE BRAKE PEDAL TO ACHIEVE DESIRED DECELERATION. ALSO, WHEN THE OHB MODE IS ACTIVATED, THE DRIVER CAN HEAR AND FEEL, THROUGH BRAKE PEDAL VIBRATION, THE STABILITY CONTROL SYSTEM PUMP OPERATION. STARTING IN LATE APRIL 2008, GM CHANGED FROM THE OHB SYSTEM BACK TO THE VACUUM PUMP SYSTEM DESIGN. ODI IS AWARE OF 264 NON-DUPLICATIVE COMPLAINTS TO ODI AND GM ALLEGING INADEQUATE BRAKE POWER ASSIST IN THE SUBJECT VEHICLES WHEN APPLYING THE BRAKES JUST AFTER A COLD START, INCLUDING ONE INCIDENT INVOLVING A CRASH INTO A TREE DURING A DRIVEWAY MANEUVER. TO ADDRESS THESE CONCERNS BY CONSUMERS, GM HAS ISSUED THREE TECHNICAL SERVICE BULLETINS. ON JUNE 4, 2007, GM RELEASED AN INFORMATIONAL BULLETIN (NO PART REPLACEMENT OR SOFTWARE UPDATES), BULLETIN# 07-05-22-002, TO DEALERS EXPLAINING THE FUNCTIONALITY OF THE OHB SYSTEM. ON NOVEMBER 29, 2007, GM RELEASED A SERVICE BULLETIN, BULLETIN# 07-05-22-007, WITH INSTRUCTIONS TO RECALIBRATE THE EBCM WITH REVISED SOFTWARE TO MAKE OHB OPERATION FEEL MORE LIKE A NORMAL VACUUM ASSIST SYSTEM. TO IMPROVE COLD START BRAKING PERFORMANCE COMPARABLE TO MY 2007 VEHICLES, GM RELEASED A THIRD SERVICE BULLETIN IN TWO PARTS, BULLETINS 07-05-25-007A (APRIL 29, 2008) AND 07-05-25-007B (MAY 16, 2008), FOR AUTOMATIC AND MANUAL TRANSMISSION VEHICLES RESPECTIVELY. THESE BULLETINS RELEASED NEW ENGINE CONTROL SOFTWARE TO CHANGE THE IDLE STRATEGY AFTER A COLD START SO THAT MORE VACUUM IS AVAILABLE FOR BRAKE POWER ASSIST. BEGINNING THE WEEK OF JUNE 23, 2008, GM WILL BEGIN SENDING LETTERS TO CONSUMERS TO MAKE THEM AWARE OF THE AVAILABILITY OF MOST RECENT CALIBRATION. A SAFETY-RELATED DEFECT HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED. ACCORDINGLY, THIS INVESTIGATION IS CLOSED. THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST. THE AGENCY WILL TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES. |

I have been following this thread and the Pontiac Solstice thread about this brake problem. I would agree, if you own one of these, you're gonna have to get aggressive about it and find out what your dealer is planning to do to make this problem right for you. Nobody should have to wait for their car to warm up two minutes before they take off. Imagine a parking valet not getting that important little tidbit of information and getting in to an accident with your Sky or Solstice? You've all paid enough money for your cars that you deserve a safe, well running Sky and Solstice. I wouldn't wait, I'd call your dealers and get them cracking on this ASAP. I'd be on it like a Gary Payton steal of Michael Jordan and a layup at the other end kissed gently off the Sonic's glass for two points, gentlemen. |
