2011 GMC ACADIA Engine Problems

I had issue with the timing chain an have check engine light is on I have heard other people having problems with there timing chain. It starts hard. I've had it looked at multiple times. I feel like this is a safety concern. It has low miles on it

The engine light came on. Had a mobile mechanic look at it, he ran a diagnostics, it showed a P0017 code. He advised to get another opinion on how to repair, as he said it may need a new engine. Took it to a local repair shop, was told the same thing. The Acadia runs fine, and only has 116K miles. The problem is that it will not pass the required emission test for annual registration and tag. The cost of a new engine was estimated at about $10K, which is more than the Acadia is worth. Was told that these vehicles have had a history of this same issue.

LOOKING INTO A CHECK ENGINE LIGHT I FOUND I HAD A MISFIRE IN A FEW CYLINDERS. LOOKING INTO IT I FOUND OIL IN MY SPARK PLUG TUBES, MY COILS WERE PERFECTLY DRY AND THE TOP OF THE TUBES WERE DRY AS WELL. LOOKING INTO THIS ISSUE I FOUND MULTIPLE TSB FORMS FOR THE ISSUE STATING THERE WAS A MANUFACTURE DEFECT IN THE HEAD. IT SAYS IT EFFECTS ALL VINS FOR ALL YEARS AS THEY USE THE SAME ENGINE.

I was driving on the freeway then my car suddenly started slowing down. I tried changing lane so i can pull over on the side of the freeway but unfortunately i couldn't get to pull over before the car completely stopped on the freeway. I called AAA. They sent a tow truck which came to the freeway to tow my car. My husband came and took me to work. The car was towed to a GMC dealership. I went to the dealership after work. I was told my car has timing chain problem and if not fixed will damage the engine. I went online to read reviews of this car only to see it was a very common problem for this year and model of GMC which if i have ever read those reviews i would not have bought a GMC. This vehicle should be recalled for this issue.

Looses power while driving. Cannot jump the battery it needs to be recharged every time. Power steering stops working while driving( low rpm and when stopped) dangerous for merging or lane changes. Engine shudders when trying to accelerate. TCM/ ECM replaced 2020. Problem still persists. Whining noise upon start of the vehicle. Auto start will not work. traction control light, check engine airbag and

The contact owns a 2011 GMC Acadia. The contact stated that the steering wheel would shake uncontrollably without warning while driving at various speeds. She also stated that the steering wheel would lock in the middle of turning the steering wheel in either direction without warning. After taking the vehicle to the dealer for routine maintenance, several warning lights appeared on the instrument panel. The contact called that dealer and was informed that the vehicle would reset itself upon restart; however, the failure persisted. A few days later, the Push to Start button failed to operate after multiple attempts and the key was used to start the vehicle. The contact had the vehicle towed back to the dealer and she was informed that the purge valve was defective and needed to be replaced. The manufacturer informed her that there were no recalls on the vehicle and referred her to NHTSA for assistance. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 130,000.

I was driving on a busy freeway, my car lost power and became very slow at only 20mph. Almost got rear ended, luckily I was able to pull over. Then check engine light came on. My engine failed and had to tow it. Mechanic said faulty timing chains destroyed my engine. Bought a used engine and is costing me over $4,000. I was lucky not to get killed. GM knows there’s a timing chains issues with these engines. People have complained about this costly and dangerous problem. They should recall and pay for the repairs. There was no warning for me until it was too late.

On July 27 at 400 pm I arrived home and my daughter went to take out the trash and I heard her scream daddy the car is on fire. I rushed outside and flames were 6 ft tall I called 911. After putting the fire out he stated th car was running doors locked so they couldn’t open the hood

Accordingly, the said vehicle first manifested a dangerous defect issue on July 14, 2021, while traveling out of town. A significant and abrupt reduction of power completely disabled the vehicle while parking in a parking space .Despite several attempts, the vehicle still fail to start. Only to notice the engine light illuminating and flashing repeatedly. At the same time the dashboard indicated a faulty reading of fuel and oil. This is a very serious and frightened situation because I received absolutely no warning before the vehicle shut down. Without reason of doubt, I do believe it is unsafe, extremely dangerous and is potentially a hazardous situation that should be investigated. Fortunately, I was in a parking lot went the problem occurred. Whereas, if the vehicle engine stopped abruptly in the mist of traffic it could have resulted with a different outcome. On July 16th the vehicle was towed to a certified GMC dealership for further inspection. Hours later, I received the service contract and a follow up call from the dealership given that the diagnostic is the Engine Control Module (ECM) and needs to be replaced. Surprisingly, to my dismay I was advised that General Motors no longer make the part and the Service Center is not sure when and if the part will be available. As of today, July 26th, no one has taken the necessary steps to remediate my situation. I have already attempted to resolve this problem by contacting the Manufacturer directly. Yet, no information on when a resolution will be made. I have been a loyal customer for several years and currently seeking answers.

Had to replace transmission. I waa sowing down to come to a stop and the car shuts off in the road while I am turning into a drive way. After getting a new gmc transmission,My speedometer is moving back and forth again. The vehicle shutters while in park. These are some of the same signs from last time.

I HAVE HAD THIS 2011 ARCADIA FOR LESS THEN A MONTH. THE DEALER I BOUGHT IT FROM ASSURED ME THAT THE ONLY ISSUE IT HAD WAS IT NEEDED A NEW A/C CONDENSER. ( PERMANENT CODES, P0008, P0332, P0017 ) (PENDING CODES P0161, P0332, P0017 ) ( STORED CODES, P0332, P0008 ) SEVERE URGENCY REPLACE TIMING CHAINS AND RELATED COMPONENTS, T CHAIN X1 T CHAIN X1 T CHAIN X2 TIMING TENSIONER X1 X1 X1 X1. I HAVENT EVEN BEEN ABLE TO DRIVE IT AND THE SOLD ME THE CAR ON FALSE PRETENSES. THEY WONT HELP ME WITH FIXING IT, THEY WONT EVEN FIX THE A/C CONDENSER. IM GOING THROUGH A DIVORCE AND I PUT THE ONLY MONEY I HAD INTO THIS CAR. I DONT KNOW WHAT TO DO.

WAS DRIVING MY CAR. GOT OFF I-79 TO GET GAS. GOT BACK IN MY CAR AND IT WOULDN'T START. HAD TO GET A JUMP. IT STARTED. STARTED DRIVING (ABOUT 4 MILES) ALL OF A SUDDEN IT STARTED MAKING A NOISE FROM THE MOTOR. IT NEVER GAVE ME A WARNING, NO NOISE OR ANYTHING BEFORE THIS. IT RAN PERFECTLY. I'M SO DISGUSTED. THEY'RE SAYING ALMOST $5000.00 WITH PARTS AND LABOR WITH A USED MOTOR. THE BEARING SPUN, THE ROLLER ROCKER BROKE OFF TIMING CHAIN, AND SOMETHING ELSE. HMM A USED MOTOR. YOU DO KNOW A USED MOTOR WILL FALL INTO THAT CATEGORY AGAIN!! I TOOK IT TO THE MECHANIC WHERE IT STILL SITS. I UPKEPT THE OIL BEFORE IT WAS DUE. IT HAS 138,706 MILES I NEVER HAD ANY PROBLEMS WITH THIS CAR AT ALL . GM I HOPE YOU DO US RIGHT BECAUSE WE STOOD BY YOU AND TRUSTED YOU!

AT 86,000 MILES, THE ENGINE NEEDED TO BE REPLACED. DESPITE OUR REGULAR MAINTENANCE AND OIL CHANGES, THE VEHICLE BEGAN TO MAKE A LOUD TICKING SOUND. WE IMMEDIATELY PULLED INTO THE NEAREST AUTO SHOP. WE HAD TWO MECHANICS (HAD CAR TOWED FOR SECOND OPINION) SAY THAT THE ENGINE NEEDED TO BE REPLACED.

WHILE SLOWING DOWN TO MAKE A LEFT TURN, MY ENGINE TURNED OFF AND WOULD NOT RESTART. UP UNTIL THAT POINT THE ENGINE WAS RUNNING FINE. I WAS FORTUNATE THAT I WAS ON A SECONDARY ROAD MAKING A LEFT TURN AT A SLOW SPEED WHEN THE ENGINE STOPPED. HOWEVER, HAD THIS HAPPENED 10 MINUTES EARLIER I WOULD HAVE BEEN ATOP A VERY HIGH BRIDGE AND WOULD HAVE BEEN TRAVELING AT ABOUT 65 MILES PER HOUR WHICH IS THE POSTED SPEED FOR I-295. HAD THE ENGINE STOPPED RUNNING ON THIS BRIDGE I HAVE NO DOUBT THAT THERE WOULD HAVE BEEN SERIOUS CONSEQUENCES. MY VEHICLE COULD HAVE GONE OVER THE RAILING AND PLUNGED 300+ FEET DOWN INTO THE RIVER. OR POSSIBLY OTHER VEHICLE TRAFFIC COULD HAVE CRASHED INTO ME CAUSING UNTOLD DAMAGE AND INJURY OR POSSIBLY SOMEONE'S DEATH. FORTUNATELY I WAS IN A SAFER AREA WHEN THE VEHICLE STOPPED RUNNING. I HAD MY VEHICLE TOWED AND THE ENGINE CONTROL MODULE REPAIRED AT MY DEALER. MY COMPLAINT IS THAT THIS SHOULD NOT BE HAPPENING. ENGINES SHOULD NOT SIMPLY TURN OFF AND STOP RUNNING BECAUSE OF SOME ELECTRONIC CONTROL PART. THIS IS A HAZARDOUS SITUATION AND I'M SURE THAT OTHER PEOPLE ARE PROBABLY EXPERIENCING SIMILAR SITUATIONS. I DON'T BELIEVE THIS IS SOMETHING UNIQUE TO MY VEHICLE, BUT ALL NEWER AND LATE MODEL VEHICLES. IT IS DANGEROUS TO THINK THAT THE AUTO INDUSTRY HAS EMPLOYED SUCH A DANGEROUS ENGINEERING AND DEVICE THAT COULD CAUSE THE DEATH OF SOMEONE. I APPRECIATE YOUR HELP REVIEWING THIS SITUATION FOR ALL THE PEOPLE.

TAKATA RECALL TRACTION CONTRO,L SERVICE STABILITRAK, ENGINE SPEED REDUCED LIGHT TURNED ON IN MY 2011 GMC ACADIA. WOULDN'T GO NO FASTER THEN 15MPH ON A 55 MPH ROAD AND THE ENGINE GOT REALLY LOUD AND ROUGH. WAS GOING 40 WHEN THE LIGHTS ALL CAME ON DRIVING DOWN THE ROAD. THIS IS VERY DANGEROUS TO DRIVE WHEN IT KEEPS DOING THIS. I'M SCARED TO DRIVE IT NOW. SPECIALLY WHEN I HAVE A BABY IN THE VEHICAL WITH ME. I'M NOT SURE WHAT CAUSES IT TO DO THIS. SOME PEOPLE SAY IT'S A GLITCH IN THE MAIN VEHICLE COMPUTER, READ IT'S A GLITCH IN SEVERAL DIFFERENT VEHICALS. THIS IS SOMETHING THAT SERIOUSLY NEEDS TO BE RECALLED AND DIAGNOSED AND FIXED IMMEDIATELY!

I WAS DRIVING MY 2011 GMC ACADIA AND ALL OF A SUDDEN THE CAR STARTED TO DECELERATE. I PULLED OVER AND TURN THE CAR OFF AND THEN THE CAR WOULD NOT START AGAIN. I HAD IT TOWED TO THE DEALERSHIP. THE DEALERSHIP IS SAYING THERE IS AN ISSUE WITH THE TIMING CHAIN. THE DEALERSHIP SAID THAT THE TIMING CHAIN FAILED. UPON DOING RESEARCH, I SEE THAT THIS IS A COMMON ISSUE WITH GMC MODELS, ESPECIALLY THE ACADIA MODEL. THE DEALERSHIP IS SAYING THAT THE REPAIR IS GOING TO COST ME $7500. GIVEN THAT THIS IS WELL-KNOWN ISSUE WITH THE ACADIA MODEL, I FEEL THAT THIS ISSUE SHOULD BE RECALLED FOR THE SAFETY OF CONSUMERS.

FOR TWO WEEKS LEADING UP TO THE 3/27/14 INCIDENT, EVERY TIME WE STARTED THE CAR THE AIR WOULD NOT COME ON AND WE WOULD HAVE TO MANUALLY TURN THE AIR ON. WHEN WE TURNED THE CAR OFF, THE AIR WOULD STAY ON. TWO WEEKS LATER, WHEN I WAS OPERATING THE VEHICLE, THE GAUGES ON THE INSTRUMENT PANEL STARTED GOING HAYWIRE DISPLAYING DOZENS OF MESSAGES, AND THE ALL OF THE GAUGES WOULD SHOOT UP, THEN BOTTOM OUT AT 0, THEN SHOOT UP AGAIN, ETC.. I TURNED THE CAR OFF, AND WHEN I CAME BACK LATER TO START IT, THE CAR WOULDN'T START BUT THE ELECTRICAL STUFF CAME ON. AFTER SEVERAL ATTEMPTS TO GET THE CAR TO START, I ROLL DOWN MY WINDOWS AND THEN TRY IT AGAIN, AND THE CAR STARTED. I DROVE IT STRAIGHT TO THE DEALERSHIP. THE DEALERSHIP REPLACED THE BODY CONTROL MODULE AND SOME WIRES AND SAID THEY FIXED THE PROBLEM. LESS THAN 48 HOURS LATER, THE SAME THING WITH THE GAUGES AND WARNING LIGHTS HAPPENED. WE IMMEDIATELY SENT AN EMAIL TO THE SERVICE DEPARTMENT SINCE IT WAS THE WEEKEND AND THEY WERE CLOSED. ON MONDAY, THE CAR DIED AGAIN, BUT THE RADIO KEPT COMING ON/OFF....I FIDDLED WITH THE RADIO AND THE CAR STARTED. I DROVE IT STRAIGHT TO THE DEALERSHIP. THEY CAN'T GET THE CAR TO "MESS UP" AGAIN, AND ARE WAITING FOR IT TO DO THE SAME THING IT DID FOR ME, SO THEY CAN FIGURE OUT HOW TO FIX IT. I AM CONCERNED THAT THE CAR IS SHOWING SIGNIFICANT ELECTRICAL PROBLEMS THAT INCLUDE SAFETY EQUIPMENT, YET GMC IS READY TO TURN THE CAR BACK ON THE ROAD. NOTE: ALL RECALLS ARE UP TO DATE AND THE DEALER HAS BEEN IN COMMUNICATION WITH GMC. *JS
