2012 GMC Acadia: jerking or lurching

Filed Sep 7, 2023 · Fuel system · TX

My 2012 GMC Acadia has had numerous issues that all lead to the fuel pump assembly. Three separate times, my cars ignition has just shut off while driving. When trying to accelerate from a stop, the car will struggle to move then jump forward nearly hitting the car infront of me. Stabilitrak warning comes on. Car randomly jerks while driving. Car will randomly not want to start but eventually does after multiple attempts.

We just purchased this 2012 gmc acadia about 30 days ago and every day we drive it we have this issue.. from a complete stop when pressing the gas the truck feels like it has no power starting to go until the rpm’s each maybe 4500 then the truck will jerk and studder through the intersections. i feel like we are going to be in a MAJOR accident while proceeding through intersections. the dealer states there is nothing they can do. there is absolutely something wrong when it jerks and stutters to move

While driving at highway speeds last week my 2012 awd acadia having a major malfunction. 1. While driving, door locks engage/disengage 2. Trans appears to slip into neutral (high rev/ no power) 3. On the dashboard digital readout the transmission "blinked" into p from d (while driving) 4. Traction control engages/disengages and the vehicle lurches forward and hard stops 5. Trans enters some sort of limp home mode where it allows me to drive only up to 60mph, @4000 RPM (like 3rd gear) this process repeated continually for over an hour drive to the dealer, normal operation appeared to occur at speeds below 45mph, but only temporarily and the issue continued again at the lower speeds. I call onstar and they pull codes for me while enroute to the dealer: ECM code =u0101 TCM code= none (failed to probe module) ABS code= u0101 ABS code= c0561 (issue with traction control system)- "service within 7 days" a quick search in automotive forums reveals several other people with almost the exact same issue, with no specific solutions.

Vehicle jerks at certain speeds, oil in throttle body, slow changing gears, RPM's not adjusting correctly . This happens everyday usually between 30-50 miles per hour. Airbag light stays on at all times and never goes off.

While accelerating, the vehicle will shudder and jerk, even vibrate violently at times. The RPM meter jumps up and down while it does that. You cannot give it gas while it is doing this (you can but it does not accelerate). I was on the interstate when the vehicle began to do this and starting losing speed quickly. Luckily, that time it only lasted a few seconds before I was able to speed back up. This could easily cause a wreck. Took it to the dealer and they found no error codes or issues. I explained what it was doing directly to the mechanic and he knew immediately it was the torque converter. He explained that my acadia would not go while it was jerking because the car is stuck in between gears. Apparently a very common issue with the acadia but no recalls. Even though I am still well under the mileage of my warranty, gm will not cover the cost to fix because my warranty expired a few months ago.

As my gmc acadia is sitting in the garage I pulled on the lift gate handle to open the tailgate. Confidence that it was good to step in an put my baby's stroller I proceeded to step in as soon as the lift gate got to it's peek the strut gave in and the gate came down about two feet or so striking me on top of my head. I managed get down as to not get heart the lift gate seems to be out of service because there is no way to open it and have it stay open. It jerks and then it closes itself.

Vehicle shudders and jerks at all speeds. It is particularly worse at lower speeds. The automatic transmission is acting like someone is popping the clutch on an manual transmission. It is scary and dangerous to drive when this is happening, however it only happens intermittently. Have found many similar complaints via google, however cannot get dealer to address the issue as no error codes are present and they cannot recreate the issue.

When operating at various speeds, inclines, and various temperatures, it lurches, fluctuations on tachometer. Dealer has known about the issue since I bought it brand new and informed me that general motors is aware of the problem with transmissions with this year and model, but has no plans on replacing transmissions or addressing this. It is a defect with my 43,000.00 dollar investment, which could directly affect the value of my investment. The mileage is 17,500. Please inform me as to what can be done about this. Sincerely, [xxx] thank you information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

Took our acadia to the dealership where it was purchased, for liftgate recall, worked fine before the work was done, now it pops and jerks at the the top of the lift. Dealership told us it was normal...I don't feel like it is.

On april 2nd while driving home from work, was stopping at a stop light and all of the sudden the driver's seat just jerked like it was coming unbolted. It now makes a squeaking noise and the seat has give to it, like its not bolted down real tight. I fear it is very unsafe. We do not even drive the car every day. The main reason I have not repaired it yet is because gm has a history, of saying it is not a manufacturers issue. And I will have to pay for the repair. I have had to have it at the repair shop 4 times already for an air bag issue. Then had to take it in for a rusted fuse in one of the headlamps, another issue they told me was not a manufacturers problem and I had to pay for it. The original light bulb was still installed in the vehicle. Of course it was a manufacturers issue. Gm also has many reasons for not making recalls on their vehicles. So at this point I feel I don't have many places to turn. I am very nervous about driving this vehicle that we pay good money for and gm does not want to take ownership for the issues with the product. So I am left with trying to research and see if anyone else has had this issue.
