2015 GMC ACADIA Power Train Problems

Torque converter is bad, shudders when shifting

The contact owns a 2015 GMC Acadia. The contact stated that while driving at various speeds, the vehicle was shuddering and vibrating while shifting gear, and vehicle failed to properly accelerate. The vehicle was taken to the local dealer who diagnosed that the transmission was faulty and needed to be replaced. The transmission was replaced, and vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 90,000. The VIN was not available.

Torque converter is going bad, hard shift when going slow then speeding up, stuttering at random times, vibration, hard shifting into reverse. No check engine light. Acadia known for transmission and torque converter problems.

Check engine light is on. Shudder and delayed reaction after engaging the gas pedal when moving forward in gear 1 & 2 then again seems to intermittently has issue with higher gears when on the hwy. Without warning, Several times the Acadia would not engage gears and wouldn't move at all after backing into the street from driveway. I had to have someone help push the Acadia back into the driveway. The Check Engine light keeps turning on and off. Had O'Riely check th OBD with code reader. "Torque Converter Selenoid is stuck 'ON'. Was informed by Costco there was n 2020 Recall for Acadia"s of my year regarding a Transmission recall Ref #N202313440.

My vehicle has a severe launch shudder in 1st gear from a stop, and while driving along when I’m in 4th gear, or during the 2-3 upshift or 3-2 downshift. It shakes the entire suv so bad I have to stop accelerating. The vehicle becomes uncontrollable which is a major safety risk.

It was shuddering while accelerating- 30-40 mph. I took it to a local shop. They diagnosed the transmission is failing. The cost to replace it would be $8,500-9,500, more than the car is worth. Also other repairs were needed, not related to the transmission, yet pushed the total repair to over $10,000.

The vehicle was perfectly fine and within 2 weeks, I needed a new transmission. When speaking to multiple shops about repairing it, they all stated it was a known problem with this transmission. This issue caused the vehicle to vibrate, made loud noise, and had problems shifting.

I have taken the vehicle to be repaired 5 times already and GM still refuses to acknowledge the full extent of the issue. My transmission was repaired under 100k miles while under warranty coverage for a slipping 3rd gear, excessive shudder, and hesitation. After a 3 attempts for repair, the 4th involved keeping the vehicle for a number of weeks and replacing internal transmission parts. Within 2 months, the symptoms returned but was out of warranty. The service center refused to diagnose it further without a $1,500 "diagnostics fee". I have brought the vehicle multiple times to the dealership, and have contacted GM seeking assistance on the matter. While the dealership service centers continue to focus on other parts and/or smaller sub-components of the transmission, my vehicle remains UNSAFE to drive outside of my immediate locality. I suffer from stalling, failure to maintain speeds, I cannot pass vehicles, I cannot...

TRANSMISSION STARTED JERKING AND SURGING FROM TAKE OFF AND AT SHIFT POINTS. FLUID LEVEL OK AND MOTOR NEVER HAS RUN HOT. CAR RAN OK AND PROBLEM WAS INTERMITTENT. DROVE CAR UNTIL RECENTLY AND PROBLEM HAS CONTINUED TO GET WORSE. VEHICLE ACTS LIKE TRANSMISSION JERKS IN AND OUT OF GEAR AT HWY SPEEDS. ISSUE STARTED AT ABOUT 98000 MILES, MOST ALL ARE HWY MILES. TRANSMISSION PROBLEM OCCURS AT ALL TEMPERATURES. TOOK CAR TO TRANSMISSION SHOP AND THEY KNEW EXACTLY WHAT PROBLEM WAS WITHOUT EVEN OPENING HOOD. THEY SAID WAVE PLATE IN 3-5 GEARS ARE CRACKED AND WOULD REQUIRE A COMPLETE REBUILD. GOT 2 ESTIMATES OF 3995.00 AND 4800.00 FROM TWO REPUTABLE SHOPS. DID RESEARCH ONLINE AND FOUND NUMEROUS ACCOUNTS OF THIS PROBLEM STARTING AS FAR BACK AS 2007 AND IN VARIOUS GM VEHICLES THAT USE THE SAME TRANSMISSION.

IT HAS BEEN SINCE I BOUGHT THE VEHICLE ... GAS GAUGE IS INTERMITTENT AND CROSS TRAFFIC ALERTS GO OFF RANDOMLY (WITH NO TRAFFIC OR OBSTRUCTIONS) PAINT HAS HAD TO BE REDONE LEATHER REPLACED TRIM REDONE ETC... THE CAR ALMOST KILLED ME AND MY CHILDREN, I'M DRIVING DOWN THE FREEWAY AT 70MPH AND SUDDENLY I LOST CONTROL OF THE VEHICLE IT SLOWED DOWN TO 49 THEN 25 LOST STEERING AND ABLE TO DRIFT TO THE SIDE BEFORE THE WHOLE VEHICLE STARTED SHAKING VIOLENTLY AND I SHUT IT DOWN AS I BELIEVED IT WOULD EXPLODE (I WAS TERRIFIED) I CALLED A DEALER AND THEY ASKED IF I TURNED IT OFF AND ON AGAIN ? ENGINE LIGHT CAME ON TRACTION CONTROL WOULD NOT RENEGADE AND MESSAGE SAID DECREASING POWER TO ENGINE WHILE IT WAS HAPPENING AND ABS LIGHT ON ... ALL FAILURES... MANAGED TO GET TO DESTINATION BUT VEHICLE WAS SLUGGISH AND JUMPING...

THE CAR DOES NOT SHIFT PROPERLY. DURING DRIVING ON SLOWING THE CAR WILL BUCK RATHER THEN SMOOTHLY CHANGE TO THE LOWER GEAR. THIS HAS BEEN AN ON GOING PROBLEM THERE WAS RE ON THE CELLENOID TO CORRECT, HOWEVER, IT IS DOING IT AGAIN.

SINCE WE HAVE OWNED OUR VEHICLE WE HAVE HAD TO MAKE MULTIPLE REPAIRS TO THE AC. OUR TRANSMISSION HAS BEEN HAD TO BE FIXED TWICE, AND IS CURRENTLY STILL NOT WORKING PROPERLY.

APPROXIMATELY 2 MONTHS AGO, THE VEHICLE SHUT DOWN IN THE MIDDLE OF HIGH SPEED TRAFFIC. SEVERAL WARNING INDICATORS APPEARED (E.G. "STABILITRACK OFF", ETC.), THEN THE VEHICLE IMMEDIATELY SHUT DOWN. PROPULSION STOPPED AND THE VEHICLE SLOWLY CAME TO A STOP. LUCKILY, MY WIFE WAS ABLE TO STEER OFF TO THE SIDE OF THE ROAD SAFELY. IT WAS TOWED TO THE DEALER, ALTHOUGH IT WAS ABLE TO RESTART. THE DEALER HAD FIXED IT, THEN RETURNED THE VEHICLE TO US. TWO MONTHS LATER, THE IDENTICAL THING OCCURRED; SAME ERROR MESSAGES FOLLOWED BY THE VEHICLE SHUTTING DOWN, IN THE MIDDLE OF DRIVING IT. WE TOOK IT BACK TO THE DEALER, AND A DIFFERENT PROBLEM WAS DIAGNOSED (WITH THE VEHICLE OUT OF SERVICE > 2 WEEKS THIS TIME). WE HAVE LOST CONFIDENCE IN THE VEHICLE, AND FEEL IT IS UNSAFE TO DRIVE.

AFTER PICKING UP OUR NEW TRUCK WE NOTICED THAT THE VEHICLE'S ENGINE WAS SHORT JUMPING AT LOW SPEEDS, ESPECIALLY WHEN IN TRAFFIC - AT FIRST WHEN THIS OCCURS YOU HAVE TO ALMOST ASK YOURSELF DID I HIT THE GAS PEDAL INSTEAD OF THE BRAKES. AFTER ONLY A COUPLE WEEKS OF OWNERSHIP WE DROPPED OFF OUR NEW VEHICLE TO BE REPAIRED. DEALER 'S GMC CERTIFIED TECHNICIAN HAD TO CONSULT WITH GMC CORPORATE TO HELP TROUBLESHOOT AND THEN DECIDED TO REPLACE THE LOWER AND UPPER ENGINE VALVE COVERS, AND THE TRANSMISSION CONTROL MODULE; WHICH WAS A QUICK FIX THAT LASTED A LITTLE OVER A WEEK. NOW OUR BRAND NEW VEHICLE IS ONCE AGAIN A LEMON AND REPEATING THE ORIGINAL ISSUE. AFTER CONTACTING GMC AND AFTER REQUESTING ANOTHER SAFER NEW VEHICLE SINCE ITS COMMON SENSE THAT A BRAND NEW TRUCK SHOULD NOT HAVE ANY INTERNAL ENGINE OR TRANSMISSION PROBLEMS BEING THAT WE HAVE...
