2015 CHEVROLET SUBURBAN Engine Problems

Replaced lifters 1,3,5,7 and added automatic fuel mgmt system bypass chip after the vehicle went into limp mode ON THE HIGHWAY. Ran for less than 2000 miles and those same lifters failed a second time and had to be replaced AGAIN. The last incident occurred after about 200 miles and had engine failure, limp mode with multiple sensor failures in the middle of the road in the dark. Limited ability to move it safely off the road.

The contact owns a 2015 Chevrolet Suburban. The contact stated while driving at various speeds, the steering wheel became stiff, and the vehicle lost automotive power. The check engine, seat belt, stabili-trak, and ABS warning lights were illuminated. The contact stated that the vehicle was occasionally towed and taken to the same local dealer on several occasions, where it was diagnosed; however, the failure was not yet determined. The transmission, fuel pump, battery, alternator, and unknown wiring were replaced at the consumer's expense; however, the failure persisted. In addition, the contact related the failure to NHTSA Campaign Number: 18V586000 (Steering); however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 117,000.

I have a 2015 Chevy Suburban with a 5.3L v8 motor. At 123,067 miles I lost the lifters in the number 7 cylinder due to the Active Fuel Management (AFM) system. This is an ongoing issue with Chevy motors from2014 to 2021. There is currently a Class Action Law Suite. I am hoping the NHTSA will issue a recall. This repaid cost me $4,000.00 to repair.

The contact owns a 2015 Chevrolet Suburban. The contact stated that while driving approximately 40 MPH, the vehicle lost motive power, with an abnormal clicking sound coming from the engine compartment. The vehicle was taken to an independent mechanic where it was diagnosed that the hydraulic lifters needed to be replaced. The vehicle was not repaired. The vehicle was then towed to the residence. The vehicle was towed to a dealer where it was diagnosed that the hydraulic lifters needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 91,800.

Clanking, stalling , wouldn’t go into gear. Had to have the truck flatbed to AAMCO. Was told transmission. Call Chevy during issue’s and told vehicle was not part of recall. Transmission had to be replaced.

The # 7 cylinder valve lifter in the 2015 Suburban engine fails when accelerating in certain situations. This has happened to this vehicle twice at and expense of rebuilding the engine. The in both cases the vehicle was accelerating into fast moving traffic. When the lifter fails the engine loses power and no longer accelerates which requires swerving out of traffic, back to the shoulder to not get rear-ended by on-coming traffic. The problem was confirmed and the service provided indicated that this was a significant issue with this particular engine. Basically, it happens to many of these vehicles. The engine has been rebuilt twice while I have owned it. When the lifter fails the check engine light comes on. These failures occurred on September 24, 2021 and again on September 9, 2023.

TRANSMISSION HAS FAILED...

OIL PRESSURE, TEMP, TAC, SPEEDOMETER, GAUGES FLUCTUATING , WHILE MANY FAILURES FLASH ON THE DRIVER INFO CENTER SCREEN, AUDIO WARNINGS ALSO.ENGINE REVS AND POWER STEERING FAILS. THIS HAS HAPPENED IN ALL DRIVING CONDITIONS, STOPPED, CITY ,COUNTRY , HIGHWAY ROADS. THIS HAS HAPPENED ABOUT FOUR TIMES, AND WE HAVE IT AT A DEALER NOW FOR THE THIRD TIME. THE FIRST DEALER COULD NOT DUPLICATE THE PROBLEM. SECOND DEALER SAID THE PROBLEM WAS A STEERING LOCK CONTROL MODULE AND REPLACED IT, THE THIRD DEALER IS STILL WORKING ON IT. THE LOSS OF POWER STEERING ,MAKING THE CAR VERY HARD TO STEER IS WHAT HAS PROMPTED ME TO MAKE THIS REPORT. THIS HAPPENED FOR THE FIRST TIME ,AUGUST 13, 2019 AND THE LAST TIME ,JANUARY 29, 2020

VEHICLE LOSES BRAKING CAPABILITY AT LOW SPEEDS, SOMETIMES VOLTAGE ISSUES CAUSE STABILITY CONTROL ERROR, AND EVEN COMPLETE LOSS OF ENGINE POWER AND VEHICLE CONTROL (ENGINE SHUTOFF). THIS HAS BEEN RECURRING APPROXIMATELY ONCE PER DAY FOR TWO WEEKS, GENERALLY AT VERY LOW SPEEDS AND TURNING INTO A PARKING SPOT. TYPICALLY, ABS ENGAGE AND POWER BRAKE ASSIST IS LOST, WHICH REQUIRES MORE MORE EFFORT TO STOP THE VEHICLE. CAN ALSO HAPPEN IN REVERSE.

THE BRAKES WERE REPAIRED, BUT THE CONTACT WAS INFORMED THAT THE ENGINE VACUUM PUMP NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 84,800.

THE 2015 CHEVROLET SUBURBAN THAT I DRIVE POWER GOES OUT WHEN I AM TURNING INTO A PARKING SPACE, MAKING A SHARP TURN, AND TRY TO COME TO A QUICK STOP. THIS HAPPENS EVERY TIME I AM DRIVING. IT ALSO DELAYS TO TURN OFF WHEN I AM PARKED. IT SOUNDS LIKE IT'S TRYING TO CRANK UP ON A LOW GAS LEVEL. SOMETIMES WHEN I AM AT A LIGHT AND TRY TO PRESS ON THE GAS, IT STALLS LIKE IT'S TRYING TO GET GAS.

WHILE DRIVING STRAIGHT ON THE HIGHWAY IN COOL, DRY CONDITIONS, THE CHECK ENGINE LIGHT BEGAN FLASHING. THE ENGINE BEGAN STUTTERING/BUCKING AND LOST POWER. DEALER ADVISED THAT IT WAS LIFTER FAILURE REQUIRING $5K REPAIR NOT UNDER WARRANTY. DESPITE THE REPAIR, THE ISSUE HAS RETURNED TWICE REQUIRING ADDITIONAL REPAIRS.

Mileage: 101,000

AT LOW SPEED (BACKING INTO A PARKING SPOT ON THE STREET) THE BRAKE PEDAL GOT VERY HARD AND THE VEHICLE WOULD BARELY STOP. I THEN DID NOT GO INTO THAT SPACE TO AVOID HITTING THE CAR BEHIND ME. I PULLED INTO A PARKING LOT ACROSS THE STREET. WHEN BACKING IN, I COULD NOT STOP (MOVING WITH CAR AT IDLE ENGINE SPEED). THE HITCH HIT THE CONCRETE WALL-HAPPILY NO DAMAGE DONE. WITH RESEARCH, I FIND THIS IS A COMMON PROBLEM THAT GM HAS NOT ADDRESSED. I USUALLY OCCURS AT SLOW SPEEDS OR STOP AND GO SLOW SPEED TRAFFIC. THIS IS UNPREDICTABLE AND VERY UNSAFE. THE VEHICLE IS A 2015 WITH ONLY 35,000 MILES. THE VACUUM PUMP (THE FAILURE) IS BOLTED TO THE ENGINE AND ENGINE-DRIVEN AND LUBRICATED BY ENGINE OIL WHICH PUTS MY ENGINE AT RISK. YET NONE OF THIS IS COVERED BY THE POWER TRAIN WARRANTY. THIS IS NOT A SLOW, BUT A SUDDEN FAILURE ITEM. VERY UNSAFE IF IT HAPPENS IN SCHOOL PARKING LOT PICKING UP MY CHILDREN, CHURCH, CLOSE SPACES (NEIGHBORHOODS, PARKING AREAS).

Mileage: 35,000

A KNOWEN ISSUE WITH THE SUBURBAN- DEAD LIFTERS, OFTEN THE DEALERSHIPS DON'T WANT TO REPAIR THE ENGINE, THEY TELL CUSTOMERS TO GET A NEW OR REBUILD ENGINE. THE ISSUE IS A HIDDEN SECRET WHICH I HOPE WITH THIS COMPLAINT GM WILL COME CLEAN AND RECALL MILLION OF CARS ON THE ROAD WITH THIS DEFECT.

AC CONDENSER BROKE, TOLD BY GM SPECIAL COVERAGE TAKE TO DEALERSHIP, DEALERSHIP SAID NO COVERAGE. HAD 3RD PARTY FIX AT REASONABLE COST, CALLED GM AND TOLD YES WE WILL PAY FOR PARTS TAKE RECEIPT TO DEALERSHIP, DEALERSHIP SAID NO! WILL NOT PAY, WILL NOT FILE, WILL NOT HELP! GM NOW SAYS WILL NOT PAY AFTER MULTIPLE PHONES STATING THEY WOULD!

TRANSMISSION STOPPING ON HIGHWAY

PURCHASED SUBURBAN FROM ALM IN UNION CITY ON 10/05/17 ON 11/04/17 THE BRAKES STARTED TO MAKE NOISE WHEN COMING TO A STOP. ON 11/06 THE BRAKES WERE MAKING ALOUD SCRUBBING SOUND WHEN STOPPING HAD TO GET BRAKES DONE AND WHEN THE MECHANIC SAW THE ROTORS THEY WERE RUSTED AND ALSO NEEDED TO BE CHANGED BUT HE COULDN'T DUE TO THE CONDITION THEY WERE IN MADE IT IMPOSSIBLE RETURNED TO ALM ON 11/7 FOR THEM TO DO THE I OWE WORK AND I WAS TOLD THEY WOULD CHECK THE ROTORS IT NEVER HAPPENED AND WAS THERE FROM 10AM TIL 7 PM. I SPOKE WITH THE SERVICE MANGER AND HE WAS GOING TO CALL BACK TO SET UP ANOTHER APPOINTMENT. ON 11/9 THE ENGINE OIL LIGHT CAME ON SAYING ENGINE OIL LOW ADD OIL 48% REMAINING. PUT A QUART IN AND MADE APPOINTMENT AT SUPERIOR CHEV TO HAVE OIL CHANGED. AT THAT TIME THE TECHNICIAN SAID THERE WERE QUITE A FEW RECALLS SO JUST MAKE ANOTHER APPOINTMENT AND HAVE OIL CHANGE AND RECALLS DONE HOWEVER HE PROCEED TO CHECK THE OIL AND EVEN WITH THE QUART ADDED THE DIPSTICK CAME BACK DRY. SHOCKED NOT WANTING TO BELIEVE THAT ALM HAD NOT ONLY FAIL TO FIX THE BRAKES THEY DIDN'T EVEN CHANGE THE OIL, BRAKES ARE A SAFETY ISSUE CARS GO THROUGH A PID AND THINGS OF THIS NATURE ARE CORRECTED BEFORE PUTTING INTO INVENTORY. MY FAMILY AND I COULD HAVE BEEN SERIOUSLY HURT DUE TO THE NEGLIGENCE OF ALM. I HAD NOT EVEN REACH THE FIRST PAYMENT AND ALL THIS HAPPENING. AND THE SERVICE MANAGER NEVER CALLED BACK . I HOPE THAT ATLANTA LUXURY MOTORS WILL BE INVESTIGATED ABOUT WHAT THEY DO PRIOR TO PUTTING CARS IN THEIR INVENTORY AND PEOPLE COME IN TRUSTING THAT THEY ARE SAFE WHEN FINANCING A AUTOMOBILE AND HAVE TO PAY 5YRS ON AND IT STARTS OFF WITH SAFETY ISSUES. THERE IS NO WAY THEY COULD HAVE DONE PID OR THEY DID AND JUST IGNORED WHAT THEY SAW. I REALIZE THE SUBURBAN WAS USED BUT SAFETY SHOULD BE A CONCERN OF THE SELLER AS WELL AS THE BUYER.

THERE WAS A NOT ANY BIG EVENT THAT CAUSED IT. AIR CONDITIONING WAS BLOWING COLD AIR ON MONDAY JUNE 26, 2017; ON TUESDAY JUNE 27, 2017 IT WAS WARM AIR EVEN AFTER DRIVING AROUND FOR 5 MINUTES. IMMEDIATELY TOOK IT TO THE DEALER WE PURCHASED IT FROM: PRIORITY CHEVROLET. THE CONDENSER HAD STOPPED WORKING. COULDN'T HOLD FREON BECAUSE THERE WAS A HOLE IN IT....?!?!?! NOT SURE OF THE CAUSE. MY CAR IS BARELY 2 YEARS OLD! I HAVE FOUR YOUNG CHILDREN IN THE MIDDLE OF SUMMER. INITIALLY WE WERE TOLD 1-2 MONTH WAIT!? APPARENTLY THIS ISN'T THE FIRST CONDENSER THEY HAVE HAD TO REPLACE. TELLS ME SOMETHING ISN'T ISN'T RIGHT WITH CHEVROLET.

TL* THE CONTACT OWNS A 2015 CHEVROLET SUBURBAN. THE CONTACT STATED THAT A STRANGE ODOR WAS PRESENT IN THE VEHICLE. SEVERAL OCCUPANTS ENDURED MIGRAINES, VERTIGO, NAUSEA, AND VOMITING WHILE IN THE VEHICLE. MEDICAL ATTENTION WAS NOT REQUIRED. THE VEHICLE WAS TAKEN TO A DEALER, BUT THE CAUSE OF THE FAILURE COULD NOT BE DETERMINED. SEVERAL COMPONENTS WERE REPAIRED, BUT THE FAILURE WAS PERSISTENT. THE FAILURE MILEAGE WAS APPROXIMATELY 18,351.

Mileage: 18,351

A/C NO COLD AIR. I WENT TO DEALERSHIP AND THEY TESTED AND SAID THERE'S HUGE HOLE. APPARENTLY THEY ONLY SAID SMALL LEAK. THEY REPLACED WITH NEW CONDENSER. I WAS FORCED TO PAY NEARLY 1,400. ALSO RESURFACE FRONT DISC BRAKE. THIS IS BRAND NEW VEHICLE AND OVER 20 VEHICLES I KNOW HAVE SAME ISSUES. THERE SHOULD BE RECALL ON THIS VEHICLE. I WENT TO DEALER AND THEY SAID DEAL WITH GM. I WENT TO GM THEY WON'T RESOLVE MY ISSUES.

WE HAVE MULTIPLE PROBLEMS WITH OUR NEW SUBURBAN. AFTER TRAVELING SLOWLY OR COASTING IN TRAFFIC, WHEN I TRY TO ACCELERATE THE VEHICLE WON'T GO AND WHEN IT FINALLY DECIDES TO GO IT SHUDDERS AND VIBRATES BADLY, IT ALSO DOES THIS FROM A COMPLETE STOP, BEEN TO THE DEALER 2 TIMES SO FAR THIS AND THE LAST TIME THEY TOLD ME "IT IS A NORMAL CHARACTERISTIC OF VEHICLE". IT IS A VERY BAD ONE AND IT WILL CAUSE A WRECK! THE RADIO DISPLAY FLICKERS ALL THE TIME EVEN WHEN BACK UP CAMARA IS ON, GM HAS NO FIX FOR THIS YET EITHER! THE VEHICLE STICKER SAYS IT HAS HEATED/AC SEATS, IT DOESN'T HAVE A/C SEATS, THEY ARE AIRRATED FROM THE AIR IN VEHICLE, THAT WAS A TOTAL MISREPRESENTATION OF THE PRODUCT ON THE SALES STICKER. GM REP HAD US TEST DRIVE ANOTHER SUBURBAN AND WE DROVE 3 DIFFERENT ONES AND NOT ONE OF THE OTHERS DID THE THINGS OUR DOES. WHEN WE INFORMED GM OF THIS THEY SAID SORRY WE DON'T QUALIFY FOR A BUYBACK/REPLACEMENT. GM DOESN'T CARE TO HELP AND ITS THEIR VERY EXPENSIVE PRODUCT. I HOPE NO ONE DIES OR IS INJURED FROM THE HESITATIONS THAT GM KNOW THESE VEHICLES HAVE THAT IS 0.7 SECONDS BEFORE THE VEHICLE WILL ENGAGE OR REENGAGE WHEN EXCELERATING FROM A SLOW ROLL OR A COMPLETE STOP.

Mileage: 2,052

WHEN DRIVING THE 2015 SUBURBAN WE EXPERIENCE AN AWFUL EAR PRESSURE AND VIBRATION. THE CAR IS NOT DRIVABLE AND IS CAUSING HEADACHES AND VERTIGO. THE PROBLEM IS KNOWN BY SERVICE TECHS AND GM. THEY BELIEVE THERE IS A PROBLEM WHEN THE CAR TRANSITIONS FROM V8 TO V4. THERE ARE MULTIPLE FORUMS ONLINE REGARDING THE ISSUE. GM HAS NOT ISSUED A FIX AS OF YET. FROM WHAT I HAVE READ, THE PROBLEM IS FOUND IN 2015 SUBURBANS, ESCALADES, AND YUKON XLS. WE PURCHASED THE VEHICLE WITH 1750 MILES ON IT. AFTER PUTTING 500 MILES ON IT, WE CANNOT WAIT TO GET RID OF IT, AND HAVE ATTEMPTED TO INITIATE A BUYBACK PROCEDURE WITH GM. *TR

THE VEHICLE HAD APPROXIMATELY 3500 MILES WHEN RETURNED TO DEALERSHIP. THE PRIMARY ISSUE WAS "RUNNING ROUGH." THE VEHICLE WAS IN THE REPAIR SHOP OVER FIVE WEEKS. IN THREE INCIDENTS PICKED UP THE VEHICLE WHEN IT WAS SUPPOSEDLY FINE. WITHIN MINUTES THE CECILE STALLED AND STARTING TO SHUTTER. WARNING INDICATORS INCLUDE ENGINE AND TRANSMISSION SYSTEM, EMISSION SYSTEM, STABILITRACK STABILITY CONTROL SYSTEM, AND ANTILOCK BRAKING SYSTEM. VEHICLE UNSAFE TO DRIVE. THE 2015 SUBURBAN WAS NEWLY DESIGNED. REPAIR BULLETINS WERE ISSUED. VEHICLE RECENTLY PICKED UP AND STILL "RUNS ROUGH." THE VEHICLE HANDLES DIFFERENTLY AS IT SHIFTS FROM V4 TO V8 (FUEL ECONOMY DESIGN) WHEN SLOWING. THIS MAKES THE VEHICLE HANDLING INCONSISTENT DEPENDING WHAT MODE IT IS OPERATING AND CAN BE UNSAFE. OTHER POTENTIAL SAFETY ISSUES WHEN RAINING, THE REAR CAMERA (BACKUP) IS NOT FUNCTIONAL. ALSO, WHEN STARTING IN REVERSE, THERE IS AN EXTENDED PERIOD THE "COMPUTER IS LOADING" AND THEIR IS NO INPUT ALTHOUGH YOUR BACKING UP. IN ESSENCE, THE REAR BACKUP WARNING SYSTEM IS NOT FUNCTIONAL. *TR

Mileage: 3,500

THE VEHICLE COMPLETELY STALLS AND LOSES ALL POWER. IT USUALLY HAPPENS WHEN YOU RUN THE VEHICLE ON THE HIGHWAY AND HAVE TO COME TO A STOP AFTER EXITING. IN MY CASE I DROVE THE VEHICLE FOR AN HOUR AND HALF AND EXITED THE EXPRESS WAY. ONCE, I EXITED AND SLOWED DOWN TO COME TO A COMPLETE STOP THE ENGINE STARTS TO RUN ROUGH AND JUST BEFORE YOU COMPLETELY STOP IT STALLS OUT. THIS HAS HAPPENED AT LEAST SEVNE TIMES ON A 1400 MILE TRIP. IT EVEN HAPPENS WHEN YOU COME TO A STOP BEHIND OTHER CARS. YOU CAN PUT IT IN PARK OR NEUTRAL AND THE VEHICLE WILL RESTART. *JS
