Sometime Cruise won't resume or set 2022 Buick Encore GX Select

[velociraptorfarmer]

We called GM about our problems , and got someone who couldn't speak or understand english , some Syrian probably , and spent 1/2 hr explaining our problem , and we said there was a know fix for it .They had no clue, and said they would hand it to someone Monday, and they would call us back .
Then we got and email back from our purchasing dealer , and they finally told me , that after some time , trial and probably error , they had fixed another one with the same problem .We called them and they said they had to replace the wiring harness and the brake pedal assembly on the other customers vehicle , and I would have to have ours looked at to determine if ours has the same fault ???????????? , it has since the day I bought it .
So we also will have to wait for backordered parts , if they order them , and now the retrofit for the heated seats and back up sensors is delayed until late fall or early winter .
I'm not taking it back to a local dealer , who was rude , wanted to charge for a scan if nothing showed , said if no code now work GM wouldn't pay for it , the wife probably didn't have it in drive when it lost engine power once , said we didn't know how to use the car , told me I was messing with the car too much - I was braking while in cruise to show them what was happening etccccccc.
I've had less problems and frustration with 5 - 15 yr old used vehicles.
If this is common for new car buyers , something has got to change . Hope another mfg starts stressing service , maybe GM will smarten up , or go out of business.
Have fun , hope you get to go on your trip.
Bye for now

Sounds identical to our problem and the solution they settled on so far.

Luckily our service experience has been pretty good. Our only major issue otherwise is that the loaners we've been getting have been absolute turds. The newest one was a 2012 Buick Lacrosse with 115k miles.

Sometime the cruise won't resume or set , the dealer said to increase speed and press resume or set , he said that worked for him , when it failed to work once out of ten tries.
It failed on me again , on the way home from the dealership , when I applied the brake while cruising behind a slow vehicle , but his instructions didn't work.
I tried a variety of things and found that if I applied the brake again it worked.
Now I'm wondering if the brake pedal position sensor may be faulty.
Before when it happened , if we stopped and turned off the engine it usually worked again , but once we stopped 3 times and turned off the engine and it didn't work again , on the way to the dealer.
I'm expecting the dealer to say it's intermittent and they can't find the problem .

Did the brake pedal assembly replacement fix the problem? I’ve got the same issue, 3x’s to the dealer, s/w update, sensor calibration, still a problem. Yesterday GM told the dealer to order a replacement (new part number) brake pedal assembly. Apparently to date they haven’t been manufactured to the drawing requirements. Vehicle is scheduled for the replacement on Sept 8. Hoping for the best.

I have a 2022 Encore GX with the same adaptive cruise issue. S/W update, sensor calibration, etc w/o success. I finally was able to demonstrate to the dealer service manager who captured an actual event on his laptop. GM told him they are aware of the problem (TSB not yet issued) and requires the replacement of the brake pedal assembly. Apparently the brake pivot tolerancing is out of spec. I’ve been waiting 3 weeks for the parts, still no ETA. Buick customer service has been worthless in helping the situation. Last weeks “update” was that they really done have an update. Just want the vehicle fixed so I can get rid of it.

We have had the issue since the day we bought it , and a bcm calibration was tried , it still happened . No code was coming up , and the local dealer said they couldn't do anything to fix it because no code showed what to do .They told me I was "messing with it " and that was why it wouldn't resume or set at times. It's gotten worse , hopefully they can get it to do it , when they try it out in Octoberat my selling dealer. I'm scheduled to have my selling dealer check it over , and if they decide there is a problem , they have had to replace the pedal assembly and the whole dash wiring harness in other vehicles that had the same problem. They expect the parts to be backordered for who knows how long. I called GM and talked to an agent who could hardly understand or speak english , and got not reply since. Pretty poor service. It has developed other issues as well , so I have a 4 point list .
Just to clarify , the problems are .
1. Cruise won't set , resume sometimes , after disengaging cruise by braking. Sometimes it won't set from the first attempt , when starting a trip.
2. The brakes grab excessively , like they are boosted more than normal , when stopping before turning onto the highway.
3. When you put it into drive , it lurches ahead , like the idle rpm is too high. You have to brake , so it won't go into traffic.
4.There was a loss of power for 5 minutes once , but there was no scan codes , read at Bruce GM , so they couldn't do anything.

UPDATE: Adaptive Cruise Control Malfunction! After waiting 4 weeks, the dealer finally got the new pedal assembly and installed it this past Monday (car was in the dealer for 9.5 hours). After approximately 200 miles of driving, so far so good. Apparently there has been a design update (movement in the pedal pivot is significantly reduced) and GM is working on a TSB which is not yet available. Hopefully this is a permanent fix. If you are experiencing adaptive cruise dropouts/malfunction, have the dealer get GM to authorize a brake pedal assembly replacement with the upgraded part.

Alright, cluster of an update:

Parts came in for ours. Turns out the dealer got the wrong harness, so we're stuck in another POS loaner indefinitely until they can determine what the correct part they need is, get it ordered, get it to the dealer and install it. Went and grabbed our stuff out of the car this morning, and the whole interior is torn apart.

I'm furious, and Buick Customer Service/GM have been incompetent and worthless. I'm looking into reaching out to lemon law lawyers because this is absolutely ridiculous. We're not paying this much to drive 10 year old turds with 125k miles.

Our car is into the selling dealer to check to see if it warrants the harness/pedal repair . Same story as the other dealer - if they don't find a problem they will have to charge us $120 ?????????? . there is a problem -since we purchased it !!!!!!!!!! . My wife said they seemed to imply , if we had spent more and purchased a Cadillac , we would't have a problem , so I guess a $40,000 car isn't expensive enough to get one that works . What a network of idiots , sarcastic , could care less bunch . We will see what happens . I don't think we have a lemon law in Canada .
Good luck with yours.

Unfortunately Canada doesn't have a "Lemmon Law" but does off a Arbitration process. I'm in the US so have no idea on the process but it may be something to check before it gets to that point.

Maybe someone from Canada on the forum can add additional information, here's a link.

Thanks

Didn't get the story quite straight from my wife - they said if I had purchased a Cadillac the retrofit for the heated seats and the back up sensors would have been done by now . We are waiting for a email to get that done as well sometime to the Encore .

 

[tl1957]

Well they finally admitted there is a problem , and they replaced the 13597423 Sensor and a 42689897 Retainer - that connects the master cylinder push rod to the brake pedal , if that doesn't fix it they say they will replace the brake pedal assembly. So we are trying it out now.

Quick update:

They managed to get the correct parts and supposedly fixed it. Car was in the shop for 8 days while they figured this out. So far it hasn't done it again, but I've literally only driven it home from the dealer so far. Seems like it already has more creaks and rattles than before given when I went to get some of my wife's things the other day, the center console, steering column, and dash were on shop towels on the floor of the shop, and the gauge cluster and glovebox were in the back seat.

I got in touch with a lawyer to see what our options were for lemon lawing the car, and he believes we have a case against GM to either force a repurchase with full refund minus $.10/mile for use, or force a cash and keep where we get a lump sum payout to keep the car.

Buick also notified the dealer to reach out and discuss a buyback themselves as well.

This has been an absolute mess, and Buick Customer Care and our dealer have been next to worthless.

When it's all said and done, it's wifey's car, so we'll see what the final numbers are what she'd rather do.

This was their 3rd attempt for us. Ended up not fixing it, since it's an issue with part of the wiring harness and the design of the brake pedal assembly itself. Supposedly there's already a redesign out for the pedal assembly.

Best of luck though!

 

[tl1957]

So far so good , we still have to probably go in for service twice to get the heated seat retrofit and the backup sensor retrofit done.

Luckily for us they did the heated seat retrofit the last time the car was in.

My dealer told me he had to disable the new cruise control in order to use the cruise control without these problems. I plan on taking it out this week. I am having problems with several other complicated software, as well.

Is your car still working , what did you do about the lemon law?

How is your car doing?

Thanks for the bulletin information , finally they created a bulletin 8 month after I had the problem . The dealership hasn't replaced the pedal assembly yet - they replaced the brake pedal position sensor and the retainer that holds the rod going to the master cylinder , and it has worked ok since.
