Car has 4 trips on rollback and one driving in for transmission problems 3 trips was when coming to a stop the car will will slide to stop almost making us hit dash of car each time there would be a warning about a minute before service transmission. One of the Trip for transmission service light I did drive it in. The car went in yesterday for transmission service again. My thinking of this is what would happen if I were driving 70 MPH and the car locked up what would happen to me and the people around me.

2017 Buick Lacrosse. Consumer writes in regards to issues with transmission. The consumer stated when accelerating from a stop, the vehicle intermittently seemed to stick or downshift into low gear. The vehicle was restarted and appeared to be normal. The dealer could not duplicate the failure.

I purchased my vehicle in June of 2018. The car drove beautifully for about 14000 miles. Then I started noticing harsh shifts at lower speeds, shifted fine on the highway. This continued on and I just thought it was normal wear. Then about 2 months after the harsh shifting started I was getting on the highway and accelerating up to speed. I then let off my gas pedal and the car stuck in gear. I tried slowing down and speeding up and the car would not shift. I had to pull over shut the car off and turn it back on during rush hour. This happened again about a month later, so I called to make an appointment at the dealer. Took my car in and the service tech asked me to ride with and show him what it is doing. So I drove the tech around about a half hour. On the way back in traffic at about 35 mph the car stuck in gear again with the tech in the car. They had the car a week and cud not replicate the issue again. They talked about reprogramming my ans but since no reported problems they could not do it. I have had the car back a month and it has happened twice again. So I will yet again make another appointment. This is very unsafe when the transmission will not shift to have to try and pull off on busy highways where there are not always safe places to do so.

Loud clunk noise during any gear change. Car does not have to be moving. I experimented this problem while shifting from park to drive, drive to reverse, reverse to park. This problem also exists shifting up and down gears. Took it to the dealer to get serviced. They flushed the transmission, reprogrammed the transmission control to no avail. The problem occurs when the engine is cold and hot

  • Automatic transmission
  • 20,200 miles
The contact owns a 2017 Buick Lacrosse. The contact stated that the gear shift lever would misshift and switch into other gears that were not selected. Secondly, the transmission would not go into park or reverse properly. To reverse, the contact had to move the lever back and forth. To park, the contact had to select park, shift into another gear, and then shift back into park. The vehicle was taken to webster city auto (129 2nd St, webster city, ia 50595, (515) 832-6638) where it was diagnosed that a new shift assembly needed to be installed. The vehicle was repaired, but the failure recurred soon after. The manufacturer was made aware of the failure and did not assist. The failure mileage was 20,200. The VIN was invalid.

I have no idea whether this concerns the takata inflators or not. While accelerating from a normal traffic speed (approximately 20 to 40mph), it seems like the transmission shifts up and down rapidly several times between lower gears. If the acceleration is terminated by by lifting your foot from the accelerator, the shifting goes away. After that, a soft pressure on the accelerator will allow the vehicle to accelerate without further unwanted shifting. This is a reoccurring problem.

On November 19, 2016, I purchased the 2017 Buick Lacrosse premium AWD. On that same day, while I was driving on the highway the overheated engine light came on, beeping sound, oil light came on, shortly vehicle indicated immediately to stop, which I did, stranded on the highway in en route to dealership. I had just left the dealership approximately five minutes ago after I purchased the vehicle. The vehicle was towed to dealership. Simultaneously at 4:48 P.M. est, onstar sent notification via email stating, "a critical issue with the engine and transmission system in your 2017 Buick Lacrosse AWD has been detected...please service your vehicle immediately." On November 20, 2016, I rescinded my contract with dealership connected to the above issues. On November 21, 2016, dealership fully refunded $47,848.19 and continued its possession of said vehicle since November 19, 2016. On September 10, 2016, I ordered the vehicle with the dealership with high expectations on a new vehicle. The dealership did not disclose to me about the above problems and safety issues prior to my purchase. I felt unsafe in the vehicle because it was making loud noises underneath the car as I drove it, for example, I felt like I was going to blow up in the vehicle. I also felt unsafe driving at low speed with the emergency lights on the highway. I felt unsafe stranded on the highway in the vehicle, waiting for the tow truck.
