“I HAVE HAD MY 2004 IMPALA INTO THE SHOP THREE TIMES NOW WITH REGARDS TO THE TRACTION LIGHT GOING ON WHEN I TURNED ALONG WITH TRAC OFF AND ABS WARNING LIGHTS GOING ON. INITIALLY THE SERVICE LIGHTS WOULD GO ON WHEN TURNING RIGHT OR LEFT. THE ABS WOULD MAKE A NOISE LIKE IT WAS CYCLING. JUST LAST WEEK ON THE HIGHWAY THE TRACTION SERVICE LIGHT WENT ON WHILE DRIVING AT 60 MPH. I HAVE HAD TO STOP AND THE BRAKES WOULD PULSATE WITH NO BRAKING CAPABILITIES THEN IT WOULD CATCH AND I WOULD BE ABLE TO STOP WITH PUMPING THE BRAKE. I ALMOST HAD AN ACCIDENT. THE FIRST TIME A REPAIR WAS MADE TWO WEEKS AGO AND REPLACED WHEEL HUB ASSEMBLIES ON BOTH FRONT TIRES AND FRONT BRAKES WERE REPLACED. THIS IS TIME FRAME WENT THE BRAKES WENT OUT. I WAS TOLD THE BACK BRAKES WERE OK. THE SECOND TIME - THE MECHANIC REPLACED THE RIGHT BEARING AFTER THE LIGHTS WENT ON AGAIN AFTER 5 DAYS OF DRIVING. NOW IT IS IN THE SHOP TO REPLACE THE WIRE HARNESS FOR THE TRACTION AND ABS WHEN THE SERVICE LIGHTS WENT ON AGAIN. THE WIRE IS ROCK HARD. *TR”
“TRACTION CONTROL SYSTEM ACTIVATES WHEN IT SHOULD NOT. BRAKE PEDAL HAS BUZZING NOISE AND PRESSURE WHILE BRAKING FROM AROUND 35 MPH. CAUSES THE VEHICLE TO JERK TO THE RIGHT. ALSO, WHEN THE TCS ACTIVATES WHEN IT SHOULD NOT, IT DOES NOT ALLOW FOR ACCELERATION AND HAS LEFT ME PULLING OUT OF A SIDE STREET TO ALMOST GETTING STRUCK BY CROSS TRAFFIC. BOTH ARE VERY DANGEROUS SITUATIONS! *TR”
