• 12/31/2021· SERVICE BRAKES

  The trailer brake system alert is going off twice in a row every 45 seconds to one minute. The chiming is highly distracting while driving and seems to be a wiring issue.

• 12/31/2016· SERVICE BRAKES

  WHEN APPLYING THE BRAKES MY CAR DOESN'T STOP 100% OF THE TIME. 1 TIME DURING HIGHWAY SLOW MOVING TRAFFIC, 3 TIMES BACKING OUT OF MY DRIVEWAY (FLAT SURFACE), 4 TIMES WHEN ON INCLINE/DECLINE OF ROAD. WHEN APPLYING BRAKES, HORRIBLE CHATTERING VIBRATION COMES FROM LEFT FRONT TIRE AREA, CHATTER VIBRATION IS FELT IN BRAKE PEDAL. NO MATTER HOW HARD I APPLY THE BRAKE THE CAR KEEPS GOING - IT WILL FINALLY STOP, BUT I ALMOST HIT THE CAR IN FRONT OF ME AT THE ONE HIGHWAY OCCURRENCE, 2 TIMES CAR FINALLY STOPPED JUST BEFORE GOING OVER EDGE OF PROPERTY WHEN PULLING FORWARD & BACKWARD TO TURN AROUND IN TIGHT AREA. IN EACH INSTANCE I AM MOVING AT A VERY SLOW SPEED. I CONTACTED DEALERSHIP, THEY TOLD ME I WASN'T THE ONLY ONE CALLING ABOUT THIS HAPPENING BUT SINCE I'M OVER 36,000 WARRANTY THEY WILL CHARGE ME TO CK IT OUT, PROBABLY CAN'T RECREATE THE PROBLEM, SAID IT WAS PROBABLY ABS BUT NOTHING THEY CAN DO ABOUT THAT, SUGGESTED I FIND A DEALERSHIP CLOSE TO ME WHENEVER IT HAPPENS AGAIN!

  At 123,000 miles the torque converter failed and caused a cascading failure through the transmission leaving me stranded in traffic. Vehicle towed to Phoenix Transmission in Weatherford. 5k later I have a new UPGRADED transmission with a warranty. Owner says they get about one a month in with the same issue.

  Came home and could smell gas. Had just filled up so ignored it. Next day, just pulling into driveway, husband could see gas pouring out the bottom below the drivers seat area.. fuel line split. Had to have it towed to dealership and paid nearly a grand to get that repaired. Warranty wouldn’t cover it..

• 12/27/2021· SERVICE BRAKES

  After a 7 hour road trip and returning to local stop and go travel in our hometown, the brakes started vibrating and the brake pedal then went hard. It took a severe downward foot thrust to get the vehicle to stop and even then still continued to roll forward a few feet. The brakes remained hard thereafter and not safe to drive- unable to brake at that point. Luckily we were not in traffic at that time or still on our road trip otherwise I am sure there would have been a serious wreck or fatality. Dealership supposedly took care of the recall repair for the vacuum pump previously but apparently their action was not sufficient. What am I supposed to do about it now? Thank you.

• 12/27/2017· STEERING

  MY VEHICLE IS HAVING A PROBLEM MUCH LIKE THAT FROM RECALL NUMBER 14743 PRODUCT SAFETY - LOSS OF ELECTRIC POWER STEERING (EPS). ON SEVERAL OCCASIONS THE VEHICLE HAS LOST POWER STEERING AND THE DEALERSHIP IS TELLING ME THAT MY SUV IS NOT COVERED UNDER THIS WARRANTY. I FEEL THAT THE SAME SAFETY CONCERNS POSED WITH RECALL 14743 APPLY IN THIS SITUATION WITH MINE AND I DO NOT FEEL THEY ARE TAKING IT SERIOUSLY. ALSO WHEN THIS OCCURRED I WAS ON THE HIGHWAY THE FIRST TIME, THE SECOND TIME I WAS TURNING ONTO THE STREET I LIVE ON, AND MOST RECENTLY I WAS IN THE PARKING LOT AT TARGET WITH MY KIDS IN THE CAR WITH ME. THIS LAST TIME I WAS ACTUALLY ABOUT TO TURN INTO A PARKING SPOT WHEN I LOST POWER TO THE STEERING.

• 12/26/2025· FUEL/PROPULSION SYSTEM

  Vehicle cranked longer than usual, noticed slight smell of fuel. After arriving home noticed fuel smell was very strong and a puddle of raw fuel under vehicle. Fuel line appears to have rubbed/vibrated against the frame of the vehicle causing the line to rupture. Date of incident 12-26-2025. No MIL or warning messages were present. The vehicle has not been inspected by anyone other than myself for this incident. I feel this issue could have resulted in serious injury or death of my entire family and possibly others on the road. The vehicle has not been modified in anyway and is in OEM configuration. We will have to have the vehicle repaired but will document as best we can. I would like to add that after a quick internet search I found this to be a common issue so I was amazed there was no recall on our Tahoe. Thank you.

• 12/26/2021· UNKNOWN OR OTHER

  Trailer brake service message constantly dinging and you can’t dismiss the message. Dealership replaced a fuse and thought they fixed it and by the next day the message was back and dinging non stop. It is so distracting it’s almost unsafe to drive. Can’t see my speed or anything on my dash because the message will not go away and the dinging noise is unbearable.

• 12/26/2021· EXTERIOR LIGHTING

  Dome lights keep flickering. Not specific to any light. All of them flash sporadically. Looks like a camera flash at night. It is beyond distracting at night and the dealership could not find what is causing it to happen. It is making driving at night dangerous because it is distracting because it can sometimes flash non stop like a strobe light.

• 12/25/2018· SERVICE BRAKES

  WHEN APPLYING BRAKE AT LOW SPEEDS (UNDER 5 MPH) THE VEHICLE CONTINUES TO ROLL WITH BRAKE PRESSED ALL THE WAY TO FLOOR. EVENTUALLY STOPS BUT THIS HAPPENS IN DRIVE AND REVERSE...SCARY WHEN PARKING AND ANOTHER CAR OR OTHER OBJECT IS IN FRONT OF YOU. NO NOISE OR DASH DISPLAY INDICATOR.

  OUR TAHOE HAS HAD AN ISSUE OVER THE PAST 9 MONTHS. THE ENGINE UNEXPECTEDLY STALLS. THIS HAS HAPPENED TWICE WHILE PULLING OUT ON TO A BUSY HIGHWAY. VERY FRIGHTENING. WE FIRST TOOK THIS TO THE DEALER ON 8/15/17. THEY SPENT HOURS TRYING TO DIAGNOSE AND FOUND NOTHING. THE STALLING CONTINUED TO HAPPEN OCCASIONALLY. EARLY DECEMBER THE STALLING OCCURRED WHILE PULLING IN TO OUR GARAGE. WE LOST ALL POWER MOMENTARILY AND IT WOULD NOT RESTART THIS TIME. I DISCONNECTED THE NEGATIVE BATTERY CABLE AND THEN RECONNECTED IT AND EVERYTHING WORKED FINE AGAIN. WE TOOK IT BACK TO THE DEALER ON 12/8/17. IAFTER RESEARCHING THIS MORE IT SEEMS NUMEROUS PEOPLE ARE HAVING THE SAME ISSUE. TRACTION CONTROL WARNING COMES ON WHEN THE STALL OCCURS. THIS TIME I WAS MORE INSISTENT THAT THEY FIX THIS AND EXPLAINED MY WIFE WAS SCARED TO DEATH TO DRIVE THIS. THIS TIME THE DEALER SAID THAT THEY HAVE CHANGED THE NEGATIVE BATTERY CABLE ON OTHER CUSTOMERS VEHICLES AND THAT HAS FIXED THE PROBLEM. MY REACTION WAS WHY DIDN'T YOU TELL US THIS LAST TIME AND WHY ISN'T THERE A RECALL? SO FAR THIS HAS FIXED THE PROBLEM. I CONTACTED GM AND THEY DID NOT GIVE ME A STRAIGHT ANSWER ON THIS PROBLE. BASICALLY THEY SAID WE MAY HAVE HAD A DEFECTIVE PART.

• 12/22/2021· SERVICE BRAKES

  Brake assist problems. When stopping/slow braking while being in heavy traffic, or drive thru, the brakes will vibrate and will not come to a complete stop without it rolling, almost into another vehicle. The brake petal will be stiff and the vehicle will continue to roll. This happens a lot, but seems to only happen during stop/start, bumper to bumper situations.

• 12/22/2019· FUEL/PROPULSION SYSTEM

  I was constantly smelling a strong odor of gas coming from the inside/outside of my 2015 Chevy Tahoe. When I purchased the vehicle in 10/23 everything appeared fine. I researched the internet to determine what the problem could be & found dozens of similar situations. People saying the fuel line rubs the undercarriage of the vehicle causing a pin hole size in the fuel line causing it to leak gas. Currently my vehicle is in the shop and the problem is TBD.

  The contact owns a 2015 Chevrolet Tahoe. The contact stated that while driving from a complete stop and while driving at various speeds, the vehicle made an abnormal whining sound. There was no warning light illuminated. The vehicle was taken to the local dealer, where the transmission was replaced. The contact stated that after retrieving the vehicle from the dealer while driving 10-15 MPH, the brake pedal was depressed but was significantly firm and failed to respond. The contact drove into a curb and struck a parking sign pole. The air bags did not deploy. The contact stated that the failure exacerbated pre-existing injuries. The dealer was contacted and advised the contact to restart the vehicle and depress the brake pedal to verify whether the brake pedal was operable. The contact followed the dealer's instructions, and the brake pedal responded as needed; however, the vehicle was towed to the residence because the contact was concerned about driving the vehicle. The vehicle was then towed to the dealer, where it was diagnosed and determined that the vacuum pump needed to be replaced. The dealer replaced the vacuum pump; however, the failure recurred while driving. The check engine warning light was illuminated. The vehicle was taken back to the dealer, where it was diagnosed and determined that the lifters had failed. The vehicle was not repaired. The vehicle was taken to a second dealer, Midway Chevrolet Plainwell Auto Dealer (381 12th St, Plainwell, MI 49080), where it was diagnosed that the fuel pump wires, the transfer case oil and seal, the engine oil coolant hose, the valve cover gasket, and other unknown parts needed to be replaced. Additionally, the dealer determined that the ball joints needed to be replaced, and an alignment needed to be performed. The dealer also determined that the air ride compressor was noisy. The vehicle was not repaired. The vehicle was then taken to a third dealer, Heritage Chevrolet, Inc. (350 W Dickman Rd, Battle Creek, MI 49037), where it was diagnosed with an oil leak.

I THEN TOOK IT TO THE DEALER WHO DIAGNOSED IT AS LOW OUTPUT FROM THE VACUUM PUMP. IT COST NEARLY $700 TO REPLACE AND IN MY OPINION SHOULD BE PUT ON RECALL AS IT IS VERY DANGEROUS TO HAVE THE BRAKES FAIL INTERMITTENTLY. I ALMOST HAD A NUMBER OF ACCIDENTS DUE TO THIS ISSUE AND HAD TO HAVE MY VEHICLE PULLED FROM THE WATER WHEN LAUNCHING MY BOAT.

ONSTAR TRIED 4 TIMES TO UNLOCK THE VEHICLE WITHOUT SUCCESS OR RECOGNITION OF THE SIGNAL FROM ONSTAR. GM SENT EMERGENCY SERVICE 3 HOURS LATER AND THEY HAD TO BREAK INTO THE CAR TO OPEN IT. IN ORDER TO UNHOOK THE CAR I HAD TO DRAG A 14' LIMB OUT OF THE WOODS AND BLOCK UP THE BACK WHEELS AND EASE THE BUS BACK ABOUT 1" TO TAKE PRESSURE OFF THE TOWING SYSTEM. I CLEARED THE BUS OUT OF THE ROAD BUT THE VEHICLE SAT IN THE MIDDLE OF THE ROAD FOR 3 HOURS UNTIL WE UNLOCKED IT.

  Front shocks failed 2 years ago. Rear shocks just failed last week. Both of these failures affect the vehicle handling. The vehicle was inspected and failures confirmed by an independent service center. Both front and rear shocks had to be replaced. The complexity of the parts and system make these repairs costly. It cost thousands of dollars for each repair. It is a $70K vehicle and was manufactured in 2015. These should not be failing so quickly. And the repair shop said this is a know issue with the Tahoe of those model years but there is not an active recall. Someone needs to investigate how many of these Tahoes have had to have the shocks replaced.

  While driving at low speeds, I am experiencing difficulty with braking. The brake becomes very hard to press down and it takes me longer to stop. I researched this and came across a recall for a vacuum pump issue. I believe this is exactly what is wrong with my vehicle. However, when I input my VIN into the recall website, it says my vehicle is not included in the recall. How can I get this issue covered without having to pay out of pocket (we were quoted over $700). I fear that I may cause an accident if I am unable to stop.

  There is a trailer brake warning that comes up, sometimes 10 times in a single mile of driving on the freeway. It beeps very loud and I cannot hear anything else. It is distracting to drive and I am unable to shut it off, I can only dismiss. I am now not sure if I can tow with my Tahoe because I fear there is something wrong with the trailer brake system. It is loud enough that if something else was wrong, I may not be able to hear it happening with the warning sound going off so often. I don't know exactly what is going on but my best guess is that it is either with the wiring, as this happens when I am not towing, or there is a sensor of some sort that is faulty. In any case, I don't think it is safe to tow because of potential hazards of the trailer brakes not working, or even worse, the trailer brakes locking up and me causing an accident.
