2017 Chevrolet Silverado

A 2017 CHEVY SILVERADO WITH A 5.3L AT 80000 MILES THE WATER PUMP WENT BAD I HAD A 2006 SAME TRUCK AND IT WAS 200000+ .MILES BEFORE I HAD TO DEAL WITH THIS ISSUE. I DON'T KNOW IF I'M THE ONLY ONE THAT HAD THE WATER PUMP ISSUE SO SOON OR IF THIS IS A COMMON PROBLEM WITH THIS TRUCK THAT NEEDS TO BE LOOKED INTO, ALSO EXCESSIVE NOISES FROM THE TRANSMITION WHEN UP OR DOWN SHIFTING AT LOW SPEEDS AND IS LIKE IF STRUGGLED TO DOWN SHIFT WHEN YOU NEED IT LIKE WHEN YOU NEED TO PASS A CAR IN FRONT OF YOU MOST TIMES YOU HAVE TO GIVE IT EXCESSIVE THROTLE AND ONLY THEN IT DOWNSHIFTS IN A VIOLENT MANNER, AGAIN DO NOT KNOW IF THIS IS SOMETHING THAT IS ONLY HAPPENING TO ME OR IF THERE IS SOMEONE ELSE OUT THERE WITH THE SAME TRUCK HAVING SIMILAR ISSUES, THANKS.

TRUCK DOWN AND UPSHIFTS HARD. WHEN SLOWING DOWN FOR A CAR IN FRONT OF ME, WHEN I GET BACK ON THE GAS, THE TRUCK HAS NO POWER LIKE IT CAN'T FIGURE OUT WHAT GEAR TO BE IN. MAKES A LOUD CLUNKING NOISE WITH LIGHT ACCELERATION FROM 1ST TO 2ND GEAR. THERE IS MAJOR HESITATION WHEN TRYING TO DOWN SHIFT NO MATTER WHAT GEAR I'M IN. PROBLEM NEEDS TO BE FIXED BEFORE SOMEONE GETS INJURED. BEEN TO CHEVY 3 TIMES FOR THE SAME PROBLEM AND ALL THEY TELL ME IS THE TRANSMISSION WILL LEARN HOW YOU DRIVE. THEY ALSO TOLD ME THERE IS NO NEW UPDATE FOR THE TRANSMISSION MODULE SO I'M SCREWED.

THE 8-SPEED AUTOMATIC TRANSMISSION EXHIBITS NUMEROUS ISSUES. 1) WHEN SLOWING DOWN TO UNDER 10 MPH, AS IF YOU WERE YIELDING TO TRAFFIC AND THEN PRESSING THE THROTTLE TO ACCELERATE THE VEHICLE, TWO ISSUES CAN OCCUR. FIRST, THE VEHICLE'S TRANSMISSION CAN HESITATE BETWEEN GEARS, PROVIDING NO POWER TO THE WHEELS. SECOND, WHEN VEHICLE DOES SHIFT INTO A GEAR, THE VEHICLE CAN LURCH FORWARD UNEXPECTEDLY AS IF YOU WERE HIT FROM BEHIND. THERE IS SOMETIMES AN AUDIBLE "CLANK" WHEN THIS ISSUE OCCURS. THIS ISSUE CAN PREVENT A DRIVER FROM SUCCESSFULLY ENTERING TRAFFIC DUE TO LOSS OF INSTANT POWER TO THE WHEELS. 2) DURING LOW-SPEED ACCELERATION, THE VEHICLE CAN HESITATE BETWEEN THE FIRST THREE GEARS, PROVIDING NO POWER TO THE WHEELS. IT HAS A SIMILAR FEEL TO A TRANSMISSION THAT WAS SLIPPING. THIS CAN CAUSE A DRIVER TO OVER-CORRECT THE DEFICIENCY IN POWER TO THE WHEELS BY APPLYING EXCESSIVE THROTTLE AND CAUSE AN ACCIDENT. 3) WHEN PROCEEDING SLOWLY IN STOP AND GO TRAFFIC, THE VEHICLE CAN SHIFT UP OR DOWN SUDDENLY, CAUSING THE VEHICLE TO LURCH FORWARD UNEXPECTEDLY. THERE IS SOMETIMES AN AUDIBLE "CLANK" WHEN THIS ISSUE OCCURS. THIS CAN CAUSE THE VEHICLE TO STRIKE THE REAR OF ANOTHER VEHICLE, IN TIGHT TRAFFIC, IF THE DRIVER ISN'T PREPARED TO APPLY THE BRAKE WHEN THE EVENT OCCURS. 4) WHEN DRIVING NORMALLY, THE TRANSMISSION MAY HESITATE TO DOWNSHIFT WHEN THE ACCELERATOR IS APPLIED AS WOULD BE NECESSARY WHEN TRYING TO PASS A VEHICLE. THIS DOES NOT APPEAR TO BE GEAR DEPENDENT. THE LOSS OF INSTANT POWER CAN PREVENT THE DRIVER FROM SUCCESSFULLY OVERTAKING ANOTHER VEHICLE IN THE EVENT THEY NEED TO CONDUCT A PASSING MANEUVER.

MANUFACTURER RECALL NUMBERN192268490 NHTSA RECALL NUMBER19V645 ON AUGUST 14, 2014, I WAS DRIVING THE 2017 CHEVY SILVERADO 4X4 WORK TRUCK ON A RURAL STATE ROUTE IN HOLMES COUNTY, OHIO. I HAD PULLED OFF ON THE SIDE OF THE ROAD TO PICK UP MY TRAFFIC COUNTING EQUIPMENT. ONCE I WAS FINISHED, I PULLED INTO A DRIVEWAY TO TURN AROUND. I BEGAN TO BACK OUT OF THE DRIVE WHEN THE BRAKE PEDAL WENT ROCK HARD, I LOST ALL PEDAL AND HAD NO BRAKES. I HIT THE GUARDRAIL THAT WAS DIRECTLY BEHIND ME WHEN I COULDN'T STOP. NO DAMAGE TO THE GUARDRAIL, BUT PLENTY OF DAMAGE TO MY TRUCK. OBVIOUSLY, I DIDN'T THINK THIS WAS RIGHT SO THE VERY NEXT DAY I TOOK THE TRUCK TO PROGRESSIVE CHEVROLET. AFTER TECHS HAD A CHANCE TO LOOK OVER THE VEHICLE, THEY SAID THE VACUUM PUMP WAS DEFECTIVE AND IT WAS REPLACED AT NO COST TO ME. THAT'S ALL WELL AND GOOD, BUT HAD THE VACUUM PUMP NOT FAILED, I WOULD NOT HAVE HIT THE GUARDRAIL.

I WAS IN AN ACCIDENT ON THURSDAY, AUGUST 22 WHERE I SLAMMED INTO THE BACK OF ANOTHER VEHICLE ON THE ROAD. I HAD AT LEAST 40 FEET TO STOP AND I LITERALLY STOOD ON TEH BRAKES AND TRUCK BARELY SLOWED DOWN AND BEFORE COLLIDING WITH THE OTHER VEHICLE. I RECEIVED A LETTER FROM GM A FEW MONTHS AGO SAYING THE BRAKE ASSIST PUMP MAY BE FAULTY AND THAT I COULD GET IT REPLACED EVEN THOUGH IF IT WERE TO FAIL THE TRUCK WOULD STILL BRAKE WITHIN "STANDARD". I DIDNT THINK ANYTHING OF IT SINCE IT WASN'T DESCRIBED AS AN EMERGENCY AND I THOUGHT I WOULD HAVE TI TAKEN CARE OF THE NEXT TIME I TOOK THE TRUCK IN FOR SERVICE. MY WIFE HAD COMMENTED ON MY BRAKES FEELING SPONGY. AFTER THE WRECK I WAS SO DISTURBED BY HOW POORLY THE TRUCK RESPONDED TO FORCIBLY DEPRESSING THE BRAKES PEDAL THAT I STARTED RESEARCHING AND I FOUND WHERE NHTSA WAS INVESTIGATING THIS VERY ISSUE IN THE 2014-16 SILVERADOS AND I FEEL STRONGLY THAT MY ISSUE SHOULD BE INCLUDED IN THIS INVESTIGATION. THE TRUCK SHOULD HAVE STOPPED AND I THINK A RECALL SHOULD BE ISSUED. THE BRAKES DO NO OPERATE WITHIN "STANDARD" WHEN THE BRAKE ASSIST PUMP STOPS WORKING.
