2009 Chevrolet Tahoe Hybrid

WE HAD A 2009 TAHOE HYBRID FOR ONLY 4 MONTHS. ON SEVERAL OCCASSIONS BEGINNING IN MARCH WHEN DRIVING AT A LOW SPEED OR COASTING DOWN HILL, 'CHECK BRAKE' LIGHTS CAME ON. I TRIED TO SLOW BY PRESSING ON THE BRAKE PEDAL AND THE BRAKES WENT TO THE FLOOR AND THE CAR WOULD NOT STOP. I HAD TO COAST TO A PARKING LOT, PUT THE CAR IN NEUTRAL/PARK AND RE-START THE CAR. THE CAR STALLED WHILE COMING DOWN HILL - VERY DANGEROUS. WE TOOK IT BACK TO THE DEALERSHIP. THEY CHARGED THE BATTERY. THE VERY NEXT MORNING BACKING OUT OF THE GARAGE,AGAIN BRAKE PEDAL WENT TO THE FLOOR AND HAD TO RE-START.

I HAVE A 2009 CHEVROLET TAHOE HYBRID THAT CURRENTLY HAS 1085 MILES OF SERVICE. THE VEHICLE HAS BEEN IN SERVICE AT TWO DIFFERENT GM DEALERSHIPS FOR 7 OF 8 WEEKS OF OWNERSHIP FOR AN ARRAY OF ISSUES CULMINATING IN TWO SERIOUS SAFETY CONCERNS PERTAINING TO THE HYBRID SYSTEM. IT WAS PLACED IN SERVICE FOR A SURGING/LUNGING PROBLEM AND SELF-ACCELERATION. THE DEALERSHIP CLAIMED TO HAVE REPAIRED THE PROBLEM, BUT IT STILL EXISTS ON A CONSTANT BASIS. WHEN RETURNING IT TO SERVICE, THEY THEN SAID THAT THE HYBRID SYSTEM WAS "SEARCHING FOR HIGHER RPM'S SO THAT IT COULD CONVERT MODES BETWEEN BATTERY AND ENGINE POWER". IT WILL REV FROM A 600 RPM RANGE TO 2000 RPM'S WITHOUT NOTICE IN TRAFFIC, CAUSING THE VEHICLE TO SURGE FORWARD. SECOND ISSUE...WHILE DRIVING THE VEHICLE BETWEEN SERVICE STAYS, I NOTICED THAT I WOULD GET A TIGHTNESS IN MY CHEST AND SERIOUS HEADACHES, WITH NO HEALTH HISTORY OF THESE PROBLEMS. MY WIFE HAS A PACEMAKER AND WAS SERIOUSLY AFFECTED THE SAME WAY, WITH JABBING PAINS IN HER HEAD, CHEST PAINS AND A TIGHTNESS IN HER NECK DURING AND SHORTLY AFTER RIDING IN THE VEHICLE. SHE DOES NOT HAVE THESE SYMPTOMS AWAY FROM THE VEHICLE. IT TOOK US SEVERAL OUTINGS IN THE TRUCK TO ASSOCIATE THE SYMPTOMS TO THE RIDE. I DECIDED TO CHECK THE VEHICLE WITH A VOLT METER AND FOUND THAT WHILE RUNNING, THE METER DETECTED 5-15 MILLIVOLTS OF ELECTRICITY IN THE SEAT RAILS OF THE PASSENGER SEAT. WHEN I RETURNED THE VEHICLE TO THE DEALERSHIP AGAIN, THE SERVICE TECHNICIAN ACCOMPANIED ME FOR A TEST DRIVE AND WAS VISIBLY CONFUSED AND SPEAKING DIFFERENTLY AFTER 20 MINUTES IN THE TRUCK. THE NEXT DAY, I RETURNED TO THE DEALERSHIP, STILL CONCERNED ABOUT THE ELECTRICAL PROBLEM. THE SERVICE WRITER WAS SHOCKED WHEN HE OPENED THE PASSENGER DOOR. THEY KEPT THE VEHICLE 8 DAYS, DECLARED IT SAFE AS COMPARED TO ANOTHER HYBRID ON THEIR LOT, AND SENT ME AWAY WITHOUT RESOLVE. THE NEXT DAY, WE TALKED TO A GM REPRESENTATIVE THAT SAID THEY WOULD NOT WORK ON THE VEHICLE AGAIN FOR ANY REASON AND WARRANTY IS VOID. *TR
