A message shift to park kept appearing when the car was in park and shut off. then i put the car in reverse and the entire care locked up. (a message from gmc -general motors llc (gm) is recalling certain 2018 chevrolet equinox and gmc terrain vehicles and 2017-2018 gmc acadia vehicles. the right front intermediate driveshaft may fracture and separate while driving.)
Front right driveshaft separated while driving causing a pull to the right.
2017 gmc acadia denali awd. while accelerating on to a highway, after moving forward partially into a lane, my vehicle locked up and would not move forward. when pressing the gas pedal, a loud griding noise would occur. weeks later, problem undiagnosed and vehicle still at gmc for repair.
Shift to park issue. when you put the vehicle in park, the vehicle does not recognize that it is in park and displays on the information screen to shift to park. the vehicle will not allow you to turn it off because it thinks the car is not in park when it actually is. this was fixed under warranty for me in 2018 with 14k miles (replaced shifter assembly) and now i have having the same issue at 39k miles. gm needs to recall these vehicles and have the old shift assembly (p/n 84159722) replaced with the new shift assembly it created in october of 2018 (p/n 13528228) when my vehicle was serviced at 14k miles, it was replaced with the old part number 84159722 which is defective as i am having the same problem again at 39k miles. now my vehicle is out of warranty and i am going to be expected to pay $700 to have the new shift assembly replaced. this should be a recall because it is a safety issue because it will not allow people to turn off their vehicles all of the way, which quickly drains battery and strands them.
The vehicle shifts very harshly between second and third gears when accelerating. sometimes it is so harsh that it slams you back in the seat. the dealer says that it is "normal". it began after owning the vehicle for one full year.
The vehicle has had ongoing issues since it was purchased in june of 2017. the 'shift to park' problem had to be fixed twice, the emergency braking system engages itself for no apparent reason which has almost caused several accidents, the horn does not work when needed in emergency situations, the headlights are so dim it's dangerous, the battery has drained and left my wife stranded 4 times, and the vehicle has a very rough idle and it almost stalls out. i attempted to work with gm to have them take the car back early (lease) and the request was recently denied. this is my 3rd acadia and it by far is the most dangerous car i have ever driven. i am now reading about a fuel pump problem that could cause the vehicle to catch on fire, a driveshaft that may separate while driving, and a faulty braking system that could cause the vehicle to lose all braking capability. i do not feel safe having my family in this car and i am requesting your assistance to help me work with gm on a resolution. i entered the date that the vehicle first started to have issues, there have been over 20 incidents over a 2.5 year period causing a safety issue or leaving my wife and children stranded.
Harmonic vibration at around 1500 rpm while holding speed any gear or mph
Tl* the contact owns a 2017 gmc acadia. while driving various speeds, the transmission hesitated to shift gears and the vehicle began to vibrate excessively. there were no warning indicators illuminated. the contact referenced gmc recall number 17109 (rear differential clutch control module). the vehicle was taken to a dealer where it was diagnosed that the struts and the motor mount needed to be replaced. additionally, field testers determined that the vehicle was operating normally. the vehicle was repaired, but the failure recurred. the manufacturer was notified of the failure, but did not assist. the manufacturer stated that the vehicle was operable. the approximate failure mileage was 209,000.
When the vehicle automatically goes into v4 mode there is a vibration inside the cabin. the vibration also sounds like a boom noise inside the cabin and the vehicle shakes while driving. the problem seems to occur at 1500-1700 rpms and will continue until you accelerate and make the vehicle go back into v6 mode. dealer attempted to fix the problem on 2 occasions but was unable to. dealer acknowledged the problem and categorized it as a vibration, drone, flutter or boom noise inside the cabin while vehicle is in afm v4 mode. problem has not been fixed.
My 2017 gmc acadis 6 cylinder awd has excessive vibrations that occur at 1400-1600 rpm and at various speeds.it seems like the transmission refuses to shift and it lasts for up to a quarter mile.vibration is most pronounced at speeds of 55-60 mph the dealer diagnosis says it is functioning normal. the struts were replace at1390 miles and motor mounts adjusted, problem remains, auto brought to dealer for recall as per bulletin 17109 but it still vibrates excessively. the lead mechanic at the dealership said the auto adjusts to the driver and said the vibrations will stop at about 2500 miles. the car now has 2900 miles and it still feels like the transmission is going to fail. the vibration is uncomfortable and although the dealership said the car is safe it does not feel so.it seems impossible for a vehicle to be functioning properly with this continual erratic vibrations.
Tl* the contact owns a 2017 gmc acadia. while driving the vehicle, the wheels locked up in 4wd mode. the dealer diagnosed that the wheel differential needed to be replaced. the vehicle was not repaired. the failure mileage was 2,500.
On 2017 acadia with it's 6txx transmission, the shifts from 2-3 feel weird (especially) when driving at slow speeds. you get a feeling as if tranny takes more than usual time to engage into 3rd gear, when already disengaged from 2nd gear. this is similar to what feeling one might get if you moved from 2nd - neutral - 3rd gear. i started experiencing this issue from approx. 5k miles. this would be risky when you are trying to merge into a yield or change lanes and this shift occurs, you momentarily feel loss of control. a quick google search on this issue and you will see folks already complaining about this on forums. *tr
