NHTSA ODI 11408008

WAS DRIVING IN 45MPH STREET WHEN I GOT A 'ENGINE POWER REDUCED' MESSAGE AND DROPPED SPEED TO 10MPH. THIS IS CLEARLY A SAFETY ISSUE AND CAN VERY WELL CAUSE AN ACCIDENT IF I'M DRIVING ON HIGHWAY OR UPHILL FOR THE MATTER.

I WAS DRIVING DOWN THE ROAD AT 55MPH - 2-LANE ROAD (4 DAYS AGO) WHEN A WARNING CAME ACROSS MY DASH THAT STATED "REDUCING ENGINE POWER". IT SLOWED MY VEHICLE DOWN A MININUM OF 20MPH AND WOULDN'T PICK UP SPEED. THE CHECK ENGINE LIGHT CAME ON. I PULLED OVER AND TURNED OFF MY VEHICLE. I RESTARTED IT AND THE CHECK ENGINE LIGHT STAYED ON. I WAS ABLE TO MAKE IT TO AN AUTO SHOP AND THEY HOOKED IT UP. IT READ A P2138 CODE. IF I HAD BEEN ON THE HIGHWAY, THIS COULD'VE CAUSED A DEVISTATING CRASH. I FOUND WHERE GM EXTENDED THE WARRANTY AND THIS FIX SHOULD NOT COST ME ANYTHING - I WILL SEE WHEN I TAKE IT IN TOMORROW.

AS I ACCELERATED FROM A STOP, THE VEHICLE LOST POWER AND THE REDUCED POWER WARNING CAME ON ALONG WITH MY ENGINE LIGHT. I COULD NOT GO OVER 30MPH UNTIL I PULLED OVER AND RESTARTED THE VEHICLE. I WAS THEN ABLE TO PROCEED HOME AT NORMAL SPEED THE CHECK GNOME LIGHT IS STILL ON.

THE HEADLIGHTS CONSTANT COMES ON AND BLINKS ON AND OFF AND WHEN THIS HAPPENS IT UNLOCKS THE DRIVERS SIDE DOOR I HAVE BEEN SITTING IN THE CAR WITH THE ENGINE OFF AND CAN HEAR THE FLICKERING OF THE LOCK JUST THE OTHER DAY I LOCKED THE DOOR MANUALLY IT UNLOCKED BY ITSELF THIS HAPPENED SEVERAL TIMES BEFORE IT ACTUALLY LOCK.I HAVE HAD TO LOCK THE DOORS MANUALLY FOR SOME TIME NOW. BACK IN OCTOBER 2020 IT WAS KILLING MY BATTERY CAUSING ME TO HAVE TO GET A BOOST CONSTANTLY TOOK IT TO THE DEALERSHIP THEY SAID IT WAS THE ONSTAR SYSTEM AND I PAYED TO HAVE IT REMOVED AND STILL THE PROBLEM STILL IS THERE. BATTERY WAS STILL DYING DUE TO THE LIGHTS COMING ON AT ANY GIVEN TIME AND DRAINING THE BATTERY. I DECIDED TO BUY ANOTHER BATTERY NO LONGER NEED A BOOST BUT THE LIGHT PROBLEM STILL REMAINS AN ISSUE

NHTSA ODI 11406255

I WAS COMING TO A STOP AT A TRAFFIC LIGHT. I RECEIVED AN ALERT ON MY DASH "REDUCED ENGINE POWER" AND MY CHECK ENGINE LIGHT CAME ON. MY CAR BECAME MUCH LESS RESPONSIVE TO PRESSING ON THE ACCELERATOR AND SEEMED TO BE HAVING TROUBLE GOING MORE THAN ~30 MPH. AN INSPECTION OF THE PROBLEM GAVE THE ERROR CODE P2138 AS THE SOURCE OF THE ISSUE.

NHTSA ODI 11405011

I WAS DRIVING ON A SECONDARY ROAD GOING ABOUT 45 MPH WHEN ALL OF A SUDDEN MY CAR DECELERATED TO 20 MPH IN A MATTER OF SECONDS. THE DASH SHOWED ME AN "ENGINE POWER IS REDUCED" MESSAGE AND MY CHECK ENGINE LIGHT CAME ON. I WAS ABLE TO SAFELY PULL OFF THE ROAD AND WAS ABLE TO GET HOME SAFELY. I TURNED THE CAR OFF FOR ABOUT 10 MINUTES AND RESTARTED IT AND IT SEEMINGLY IS FINE NOW BUT THIS IS TERRIBLY UNSAFE. TO MY KNOWLEDGE THERE IS NO RECALL OR ANY WORD ON THIS FROM GM.

WHEN I WAS DRIVING HOME FROM WORK TONIGHT. I WAS TAKING THE RAMP TO GET ON TO THE HIGHWAY AND MY CAR GAVE ME A WARNING THAT THE ENGINE POWER WAS REDUCED AND MY CHECK ENGINE LIGHT CAME ON AND MY CAR WAS IMMEDIATELY RESERVED TO ONLY GOING 20 MPH. THIS IS VERY UNSAFE AS I WAS TRYING TO MERGE ONTO THE HIGHWAY.

NHTSA ODI 11403785

WHILE DRIVING ON THE HIGHWAY DOING 55 MPH MY VEHICLE BEGAN TO STUTTER AND THEN IMMEDIATELY DROPPED TO A SPEED OF 20 MPH. IT WOULD NOT ACCELERATE ANY FURTHER. CHECK ENGINE LIGHT CAME ON AS WELL AS'REDUCED ENGINE POWER' MESSAGE. I PULLED OVER AND SHUT THE CAR OFF, WAITED A FEW MINUTES AND RESTARTED. IT DROVE THIS TIME AT A SPPED OF 35. MADE IT HOME WITHIN A FEW MINUTES AND LET THE CAR SIT. THE NEXT DAY THE CHECK ENGINE LIGHT WAS STILL IN BUT THE CAR DRIVE AT REGULAR SPEED.

NHTSA ODI 11403017

WHILE RIDING ON THE HIGHWAY AT 70MPH I EXPERIENCED A TOTAL LOSS OF POWER. THE CAR WARNED ME AND THE ENGINE LIGHT CAME ON. I COULD NOT ACCELERATE BEYOND 30 MPH. WHEN I HAD IT CHECKED WITH A CODE SENSOR IT TOLD ME THERE WAS AN ISSUE WITH THE THROTTLE POSITION SENSOR. THE CODE WAS P2138. THIS CREATED A VERY DANGEROUS SITUATION ON A QUICK MOVING HIGHWAY.

POWER STEERING IS LOCKING UP WHEN MAKE A TURNAROUND OR FOR A TURN WHEEL IN MOTION. THE CAR WILL BE ON AND WHEN THE POWER STEERING IS ABOUT TO LOSE THE POWER, MY STEREO SCREEN WILL BLACK OUT ALONG WITH THE STEERING WHEEL LOCKING. IT FEELS AS THOUGH MY POWER STEERING IS OUT WHILE MAKING A TURN. THIS DOES NOT HAPPEN, ONLY HAPPENS RANDOMLY.

WHILE DRIVING ON THE HIGHWAY AT ACCELERATED SPEED DASH WILL SAY REDUCE ENGINE SPEED IT WILL DROP TO 30MPH AND WILL NOT INCREASE, MIND YOU I'M ON THE HIGHWAY WITH OTHER CARS AND 18 WHEELERS. FORTUNATELY I WAS ABLE TO PULL OVER AND SIT THIS HAS HAPPENED MORE THAN ONCE, AND READING THE COMPLAINTS I'M NOT THE ONLY ONE. THANKFULLY THIS WAS NOT RESULTING IN A ACCIDENT/ DEATH. MY CONCERN IS WHY HAVEN'T THIS BEEN RECALLED! SOMEONE NEEDS TO LOOK INTO THIS MATTER. DUE TO THE FACT THAT NEXT TIME SOMEONE MAY NOT BE AS FORTUNATE AS THE REST OF US. CHEVY NEEDS TO ADDRESS THIS ISSUE BEFORE IT TURNS TRAGIC. THEY HAVE MULTIPLE COMPLAINTS.

THE VEHICLE RUNS FINE OTHER THAN WHEN THE PROBLEMS START ACTING UP. IT IS A BCM ISSUE INVOLVING THE STABILITRAK AND ABS. EVERY FEW WEEKS OR SO, I'LL GET 3 SERVICE LIGHT UPS IN MY DASH STATING 'SERVICE VEHICLE SOON, SERVICE STABILITRAK, SERVICE BRAKE ASSIST, REDUCED POWER STEERING DRIVE WITH CARE' AFTER COMING TO A STOP. WHEN I GO TO TAKE OFF THE CAR WILL REV UP AND DOWN THEN THOSE MESSAGES POP UP AS I CANNOT SPEED UP OR DRIVE. ONCE THE VEHICLE COMES TO A STOP IT SHUTS OFF AND WON'T TURN BACK ON UNTIL ABOUT 10 MINUTES LATER. I'VE PUT $700 IN IT REPLACING SPEED SENSORS, VACUUM PUMP AND VACUUM SENSOR AND THE PROBLEM STILL OCCURS. IF IT WERE TO HAPPEN ON THE HIGHWAY THIS COULD BE VERY DANGEROUS AS IT ALREADY OCCURRED AT AN INTERSECTION STOPLIGHT IN COLUMBUS OHIO

REDUCED ENGINE POWER WARNING CAME ON WITH ENGINE LIGHT CAUSING VEHICLE TO SLOW DOWN ABRUPTLY; CODE P2138 READS ON ENGINE DIAGNOSTIC

NHTSA ODI 11400101

I WAS DRIVING ON THE PARKWAY AND MY CAR SUDDENLY MADE A CLUNKING NOISE WITH A NOTICE THAT POPPED UP SAYING REDUCED ENGINE POWER AND DROPPED DOWN TO 20 MPH. I WAS ABLE TO SAFELY PULL OVER, BUT THIS WAS EXTREMELY DANGEROUS AND I ALMOST GOT HIT ON A 4 LANE ROAD HIGH SPEED ROAD. I WAS NOT ABLE TO ACCELERATE MY CAR PAST 20MPH. THE CHECK ENGINE LIGHT REMAINED ON EVEN AFTER PULLING OVER AND RESTARTING MY CAR AFTER 30 MINUTES. MY CAR IS OUT OF WARRANTY AND WILL NOT BE COVERED.

VEHICLE IS PLACED INTO THE PARK POSITION WHILE FOOT IS ON THE BRAKE. ONCE DASH SHOWS THAT IT IS IN PARK, FOOT IS RELEASED FROM THE BRAKE AND ENGINE IS SHUTOFF. AT THIS TIME A MESSAGE DISPLAYS ON THE DASH CONSOLE "ACTION REQUIRED: SHIFT TO PARK". THIS OCCURS THE MOST OFTEN ON AN INCLINE UPON WHICH THE MESSAGE "SWITCH TO PARK" LEADS TO CONCERN OF THE ROLLING BACK OF THE VEHICLE. WHILE THE MESSAGE IS DISPLAYED YOU ARE UNABLE TO TURN THE CAR OFF WHICH WILL EVENTUALLY LEAD TO THE BATTERY BEING DRAINED. THE ONLY RESOLUTION THAT I AM AWARE OF OTHER THAN GOING TO THE DEALER IS TO START THE CAR BACK UP (ENGINE WEAR, ADDITIONAL C02 EMISSIONS) AND ATTEMPT TO PLACE IT IN PARK AGAIN WITH THE HOPE THE MESSAGE WILL DISPLAY. IN PERFORMING RESEARCH THIS ISSUE IS DUE TO A POORLY MANUFACTURED MICROSWITCH WITHIN THE SHIFTER ASSEMBLY, THE PERMANENT FIX IS TO HAVE THE DEALER REPLACE THE ENTIRE SHIFT ASSEMBLY.

TL* THE CONTACT OWNS A 2016 CHEVROLET MALIBU. THE CONTACT STATED HE WAS PARKING THE VEHICLE AND THE WARNING LIGHT ILLUMINATED WITH A MESSAGE TO SHIFT TO PARK. THE CONTACT THEN SHIFTED THE VEHICLE BACK INTO DRIVE AND BACK INTO PARK YET THE ERROR MESSAGE STATED SHIFT TO PARK. THE CONTACT STATED HE TRIED TO TURN THE VEHICLE OFF AND THE ENGINE SHUT-OFF HOWEVER, THE HEADLIGHTS, INTERIOR LIGHTS, AND THE RADIO REMAINED ON. THE CONTACT STATED THE FAILURE WAS INTERMITTENT. THE VEHICLE WAS TAKEN TO MIDWAY CHEVROLET (2323 W BELL RD, PHOENIX, AZ 85023) WHERE THE DIAGNOSIS WAS THE PARK FAILURE MECHANISM. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE BUT OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS 93,863.

"SERVICE PARK ASSIST SYSTEM" ALWAYS COMES BACK NO MATTER HOW MANY TIMES I'VE TAKEN IT TO A CHEVY DEALER! NO KNOWN FIX - STRAIGHT FROM GM THERE ISN'T ANY KNOWN FIX. THEY THOUGHT IT'S WHEN YOU USE REMOTE START ... WELL I DIDN'T USE THE REMOTE START AFTER CHEVY "REPROGRAMMED" THE CAR AND THE MESSAGE CAME BACK AND I CANNOT USE THE PARK ASSIST SYSTEM PLUS WHY HAVE A FEATURE THAT CANNOT BE USED. CAR IS BELOW 50,000 MILES AND VERY LIGHTLY DRIVEN - THE AVERAGE SPEED ACCORDING TO THE CAR'S COMPUTER IS 38 MPH. ALSO SERVICE TRANSMISSION COMES UP WITH SOME SOLENOID TROUBLE CODE AND DISPLAYS "SERVICE TRANSMISSION" AT FIRST INTERMITTENTLY, BUT NOW EVERY TIME THE VEHICLE IS STARTED. IT BANGS INTO WHEN SHIFTING FROM 1 TO 2 WHEN DRIVEN. THE BODY PANEL ON THE DOOR BETWEEN THE DOORS IS FLAKING. I'VE GOTTEN A "SHIFT TO PARK" MESSAGE WHEN THE VEHICLE WAS ALREADY IN PARK WHICH DRAINS THE BATTERY.

WHEN VEHICLE IS PLACED IN PARK, GET "PLACE IN PARK" MESSAGE ON DASH. IF NOT CLEARED, DASH LIGHTS STAY ON AND DRAIN BATTERY LEAVING DRIVER STRANDED. THIS COULD LEAD TO A VERY UNSAFE CONDITION, DEPENDING ON WHERE THIS OCCURS. DOING A SEARCH OF THE FIRST 70 CLAIMS ON YOUR SITE; 30% OF THEM ADDRESSED THIS ISSUE. WHY HAS NOTHING BEEN DONE TO RECTIFY THIS UNSAFE CONDITION? CLAIM #'S LOOKED AT: 11385598, 113384695, 11377868, 11377077,11373245, 11372867, 11367012, 11365172, 11363789. 11363275, 11361450, 11360384, 11360062, 11355051, 11353844, 11352179, 11351612, 11351422, 11350951, 11349692, 11348857. THERE IS A SERVICE BULLETIN # 19-NA-206 BY GM (SEE ATTACHMENT) ON THIS ISSUE, BUT IT DOES NOT COVER THE REPAIR UNDER WARRANTY, EVEN THOUGH IT EFFECTS SEVERAL YEARS AND MAKES. THIS WOULD SEEM TO BE A MANUFACTURER DEFECT OR QC PROBLEM, NOT SOMETHING INDUCED BY THE OPERATOR. THOUGH NO DEATHS OR INJURIES HAVE BEEN REPORTED BY THIS PROBLEM, ONE COULD SPECULATE THERE MAY HAVE BEEN SOME OR COULD BE. USUALLY THE QUESTION OF YOUR BATTERY BEING DEAD IS NOT ASKED AT THE DEATH OR INJURY SITE. THIS ISSUE CAN NOT ALWAYS BE DUPLICATED AT THE DEALERSHIP, SO IS OFTEN TURNED AWAY. THIS PARTICULAR VEHICLE WILL DO THIS MULTIPLE TIMES AND THAN STOP FOR AWHILE, THAN ACT UP AGAIN. EACH TIME IT HAS BEEN TAKEN IN TO BE LOOKED AT, THERE ARE NO CODES, AND THE SYMPTOM CAN NOT BE DUPLICATED. DRIVE IT HOME AND IT WILL HAPPEN AGAIN, OR NOT. LAST TIME IT TOOK TWENTY MINUTES OF TURNING CAR ON AND OFF, SHIFTING IN AND OUT OF PARK, ETC TO GET CAR TO SENSE IT WAS INDEED IN PARK. I AM SUBMITTING THIS REPORT FOR A FRIEND BUT WOULD LIKE ALL FOLLOW-UP INFORMATION TO PASS ONTO HIM.

MOST TIMES, WHEN I'M DONE DRIVING AND SHIFT MY CAR TO PARK A WARNING COMES UP MY DASH SAYING 'SHIFT TO PARK' EVEN WHEN THE CAR IS IN PARK. I THEN HAVE TO RESTART MY CAR, CHANGE THE GEARS AND HOPE IT DOESN'T GIVE ME THAT MESSAGE AGAIN. I OFTEN HAVE TO REPEAT THIS PROCESS 2-3 TIMES AFTER I'M DONE DRIVING AND ATTEMPTING TO PARK AND SHUT OFF MY CAR. IT DOES NOT HAPPEN EVERY TIME THAT I SHIFT MY CAR TO PARK AND TRY AND SHUT MY CAR OFF, BUT IT HAPPENS A LOT OF THE TIME. IT'S VERY FRUSTRATING AND TIME CONSUMING. THIS HAS BEEN HAPPENING ON AND OFF FOR A FEW MONTHS NOW. MY SISTER ALSO HAS A 2016 MALIBU AND HERS IS DOING THE SAME EXACT THING.
