I own a 2019 buick lacrosse e-shift (VIN#[xxx]). Over the last 4-5 mos. I have had 3 incidents where the e-shift mechanism has gone into park without touching the shift control. 1. First occurrence - approx. 5 months ago car was in drive at very slow speed entering parking slot with foot lightly depressed on brake. Car changed to park on it's own. Stopped abruptly, gears grinding, jerking me toward steering wheel. 2. Second occurrence - around 10/10/20, car was in drive, foot lightly depressed on brake, waiting to make left turn at stop light. Car changed to park on it's own. Again the car stopped abruptly, gears grinding, jerking me toward steering wheel. I scheduled appointment with dealer maintenance on 10/13/20. They could not replicate the problem. Asked for me to return the car so they could have overnight. Due to covid escalation have not scheduled appt. 3. Third occurrence - on 12/11/2020, I was waiting at a red light, car in drive, foot fully depressed on brake, and the car shifted to park on it's own. I heard the car locks click, and wondered what caused that. When light changed and I tried to accelerate, the car did not move, and it was then I noticed it was in park. I intend to take the car back to the dealer for them to see if they can replicate. They had nothing in their database on 10/13/2020 reflecting other complaints. I'm somewhat skeptical they can replicate due to the random occurrences. But it definitely seems to be in the shift park component of the car I am now very hesitant about driving this car. Since it happens randomly, and abruptly, with no forewarning, I am concerned for my safety. My questions are: 1. Has anyone reported a similar problem to your group? 2. What other information do you require? 3. What other actions should I take? 4. What other groups can I contact to inquire about the problem? Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

On 8-6-2020, (about 11 am) while driving (about 70mph) north on i43 in eastern wisconsin, at a point north of sheboygan, the message 'service power steering' appeared on the dash. When I started to drive off to a rest stop, I realized the steering was very stiff and required extra effort to guide the car, the 'electric power steering' (eps) had completely failed. How could this happen when the car was only 7 years old with 64941 miles, less than 10k mi/yr!!! I carefully drove the car to bergstrom buick gmc in green bay wis. The diagnosis was the entire eps gear box had to be replaced with a cost near $2500. I was stunned. I complained to the service manager that because of the cars age & elapsed miles, this should not have happened! I further stated that I could understand that something like this might happen after 10 years & 100k miles, but not before!! He replied the car was out of warranty and that failures like this can happen. Eventually the car was satisfactorily repaired, copy of the bill attached. My contention is that this is not only a reliability issue, but more importantly a safety issue. When my wife & I purchased the car, we were both retired and did not have the daily grind of driving to/from work in all kinds of weather. In fact the car was driven minimally in adverse conditions. When this failure occurred, I had the composure to safely steer/guide the car, had my wife been driving, the incident could have had a catastrophic result. I now have 'much pause' about the reliability/safety of eps vs hydraulic ps (hps), if & when this will happen again! A similar complaint was filed with buick gmc customer service.

The steering is tight, hard to turn the front wheels. It makes a whining & grinding noise when turning. It sounds like it's rubbing against something in the steering column. I've had it to 3 mech's, plus I called buick. They all said they didn't know what the problem was. It seems this is a problem with many 2006 lacross' . This happens from 0 to 60 MPH

My 2006 buick lacrosse has a squealing , moaning noise, coming from the steering column, for 2 yrs now. This is happening more & more, very hard to steer. What will happen when I can't steer it any longer , a bad accident. I've had it looked at 4 times, no one can tell me what is wrong with it. Upon looking at the other complaints, on-line, I see it could be the steering box, line, or r & p. Why hasn't gm recalled this problem, since they know about it?

Control arm bushing failed, causing the control arm to grind into the sub frame of the car. The sub frame is aluminum and was damaged very quickly. This issue gave no indication and only became apparent under visual inspection while the car was being serviced for another complaint. The sub frame could fail completely causing steering suspension and brakes to fail.
