2009 Chevrolet Tahoe Hybrid

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

I HAVE A LARGE CRACK IN MY DASH. THERE WAS NO ACCIDENT OF ANY KIND DONE. IT JUST SPLIT.

I REPORTED THIS SEVERAL TIMES TO CHEVROLET I WAS NOT HAPPY WITH THEIR RESEARCH. I AM HAVING ISSUES WITH THE BRAKES IN MY CAR. SOMETIMES WHILE BRAKING THE BRAKES WILL AUTOMATICALLY DISENGAGE AND YOU FEEL LIKE YOU ARE BEING THROWN FORWARD. I TOOK THIS TO SEVERAL CHEVY DEALERSHIPS WHILE MY CAR WAS UNDER WARRANTY AND THEY COULD NEVER FIND THE ISSUE. I AM STILL HAVING THE SAME PROBLEM AND SINCE MY WARRANTY EXPIRED THEY TOLD ME, I WOULD HAVE TO PAY FOR THE DIAG. I FEEL THAT SINCE I DID REPORT THIS WHILE IT WAS UNDER WARRANTY I SHOULD NOT HAVE TO PAY FOR MORE DIAG. I INITIALLY THOUGHT IT WAS JUST AN ISSUE WITH MY CAR, UNTIL A NEIGHBOR WITH THE SAME CAR ASKED IF I EXPERIENCED THE SAME ISSUES MY CHEVY CARES CASE NUMBERS : [XXX], [XXX] AND [XXX]; [XXX]*DT PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).*JB

MY 2009 HYBRID TAHOE ACCELERATES UNCONTROLLABLY ON OCCASION. THE ISSUE ARRISES COMMONLY IN STOP-AND-GO TRAFFIC WHEN THE HYBRID SYSTEM STARTS/STOPS THE GASOLINE ENGINE REGULARLY. I NOTICE IN MANY CIRCUMSTANCES WHEN SWITCHING GAS/ELECTRIC MODES THE VEHICLE LURCHES FORWARD. THE FEELING IS THE SAME AS LETTING OUT THE CLUTCH QUICKLY ON A VEHICLE WITH A MANUAL TRANSMISSION. I HAVE DONE AS MUCH RESEARCH AS I CAN AND IT APPEARS THE PROBLEM POINTS TO ISSUES WITH THE TRANSMISSION FLUID PUMP(S) AND/OR CONTROL MODULES. WHEN THE SYSTEM OPERATES ON THE GAS ENGINE, THE HYBRID TAHOE'S TRANSMISSION RELIES ON AN ENGINE DRIVEN HYDRAULIC FLUID PUMP. WHEN THE SYSTEM SWITCHES TO ELECTRIC MODE, AN AUXILIARY TRANSMISSION FLUID PUMP TURNS ON, DRIVEN BY AN INDEPENDENT ELECTRIC MOTOR. THE LURCH I DESCRIBED RESULTS FROM WHAT I BELIEVE TO BE A FAILING PUMP OR CONTROL MODULE, OR A COMBINATION OF THE BOTH WHICH ENGAGES GEARS WHEN IT SHOULDN'T. THIS LURCH IS RATHER DANGEROUS AS I HAVE HAD TO JUMP ON THE BRAKES MANY TIMES TO AVOID REAR ENDING OTHER DRIVERS. I HAVE SPOKEN WITH SEVERAL INDIVIDUALS WHO OWN, DRIVE OR HAVE DRIVEN THESE GMT900 SERIES HYBRIDS (2008-2013 CHEVY TAHOE/SILVERADO HYBRIDS, GMC YUKON HYBRIDS, CADILLAC ESCALADE HYBRIDS) ALL INDIVIDUALS HAVE DESCRIBED THE DREADED LURCH. SOME SAY REPLACING THE ELECTRIC AUXILIARY TRANSMISSION FLUID PUMP SOLVES THE PROBLEM, OTHERS STILL HAVE LURCHING ISSUES. ONE INDIVIDUAL WHO DRIVES A CADILLAC ESCALADE HYBRID CLAIMED TO HAVE ACTUALLY REAR ENDED SOMEONE DUE TO THE UNCONTROLLABLE LURCH. AS FOR MY PERSONAL CAR, THE LURCH OCCURS IN STOP AND GO TRAFFIC AND OCCURS AT LEAST ONCE A WEEK, SOMETIMES MORE. THANKFULLY I HAVE NOT BEEN INVOLVED IN AN ACCIDENT YET, HOWEVER I FEEL ONE MAY BE IMMINENT.

WHEN I PRESS DOWN ON THE GAS, MY VEHICLE STALLS ABOUT FIVE SECONDS BEFORE IT ACTUALLY TAKES OFF. WHEN I TRY TO STOP, IT DOES NOT STOP RIGHT AWAY AS I PRESS DOWN ON THE BREAK. I'VE ALMOST REAR ANOTHER VEHICLE ON SEVERAL OCCASIONS WHILE SITTING AT A RED LIGHT. I HAVE TO STAY AT LEAST 15 FEET AWAY FROM THE VEHICLE IN FRONT OF ME. MY VEHICLE HAS SHUT DOWN WHILE I WAS DRIVING. MY ENGINE LIGHT COMES ON AND GOES OFF PERIODICALLY. IF I TURN MY WHEEL TO SHARPLY (REVERSE OR FORWARD), IT JERKS, MAKES A LOUD NOISE, AND THEN IT FEELS LIKE ITS ABOUT TO CUT OFF. I FEEL REALLY UNSAFE DRIVING, HOWEVER, I HAVE NO CHOICE BECAUSE I HAVE TO WORK.
