When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

Recalls on the 2017 Buick Lacrosse

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2017222 393 units in Canada

Suspension

On certain vehicles, the rear-suspension toe-links may have been installed incorrectly (i.e., in the reverse direction). If a toe-link is installed in this incorrect direction, the bolt at the outboard attachment could come loose and fall out over time, which could cause the toe-link to disconnect from the rear-suspension system. If a rear-suspension toe-link becomes disconnected, the driver may lose the ability to control the vehicle, which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect and reorient the toe-links as required.

Recall 2017097 36 units in Canada

Steering

On certain vehicles, the cable seal of one or both of the electric power steering (EPS) connectors may not be properly seated which could allow water to enter and corrode the connections. This could lead to increased resistance in the EPS circuit which could result in intermittent or permanent loss of the steering assist. A loss of power steering assist could unexpectedly increase steering effort which would increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will ensure the connector is fully seated and secure it in place.

Missouri City, TX

SUSPENSION

This vehicle has major suspension issues containing the complete strut assembly, lower control arms, and strut yokes/forks, which can not be replaced due to the discontinuance of the vehicle and parts itself. Because of this the car cannot receive an alignment which cause the tires to be eaten up at a rapid rate. When going over a bump in the highway the steering column goes one way while the car goes another. The car slides all over the road. Extreme safety concerns for my family and I.

SUSPENSION

The vehicle was taken to the dealer, who diagnosed a failure with the front driver's side strut. The vehicle was not repaired because parts were not available. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was unknown. The VIN was not available.

AIR BAGS

The air bag warning light in the dash came on intermittently during driving. I took the vehicle to the dealer for service December 27, 2023, since it was a safety issue that the authorized dealer needs to take care of. At first, they said it was a bad battery and the safety system needed reprogramming. Which they did for about $800. When driving home from the dealer the air bag light came back on so a few days later I returned the car to the dealer. Then they said it was the passenger seat safety module that needed to be replaced. That was back in January of 2024, over 6 months ago. At that point I learned that the car is not drivable since the air bag could deploy at any time or would not function if requested in an accident. General Motors says they do not have the part that is critical to the operation of the air bag system to replace. That was over 6 months ago, with no prediction when they will have the part. This is a critical part of the safety system that they can't replace which leads me to believe there is more to this than they are telling me!! Federal law requires them to have parts for vehicles less than 7 years old - they don't!! How many other vehicles have this part? Is the part defective since it failed without any other causes that could be identified? Why can't they replace this critical safety part after 7 months of waiting with no end in sight!!!

ENGINE

PURCHASED VEHICLE JULY 25, 2020. TOOK THE CAR FOR ITS FIRST OIL CHANGE, IN OCTOBER. ON NOV 23, 2020, THE CAR ENGINE LIGHT CAME ON WHILE DRIVING ON THE HIGHWAY. ERROR CODE: P0430 "CATALYST SYSTEM LOW EFFICIENCY BANK 2". ON NOV 24, 2020, I TOOK THE CAR TO "RICK MATHEWS GMC/BUICK DEALERSHIP" FOR DIAGNOSTIC AND REPAIR. THEY PLACED AN ORDER FOR THE PARTS NEEDED FOR REPAIR AND TOLD ME, THAT MY CAR WAS DRIVABLE. ON DEC 4, 2020, I WAS HAVING PROBLEMS WITH DRIVING ON A CITY STREET WITH THE CAR SHAKING, I WAS SCARED TO TAKE THE HIGHWAY BUT THAT WAS MY ONLY WAY HOME, AND THE LOUD ENGINE NOISE AND SHAKING CONTINUED. ON DEC 7, 2020, I TOOK MY CAR BACK TO THE DEALERSHIP AND THEY TOLD ME MY CAR WAS INOPERABLE BECAUSE THE CATALYTIC CONVERTER HAD CRACKED AND THE PARTS WERE STILL NOT AVAILABLE TO COMPLETE REPAIRS. THAT DAY THEY PROVIDED A RENTAL/LOANER VEHICLE FOR ME TO DRIVE TO WORK UNTIL THE CAR WAS REPAIRED. ON JAN 13, 2021, I HAD TO SWAP OUT VEHICLES BECAUSE THE PART WAS STILL NOT AVAILABLE TO COMPLETE REPAIRS. IT IS NOW FEB 26, 2021, AND THE DEALERSHIP HAS TOLD ME THAT MY CAR IS FINALLY BEING REPAIRED. THIS ENTIRE TIME, I HAVE CONTINUED TO PAY FOR THE MONTHLY COST OF MY PERSONAL CAR LOAN WHILE NOT BEING ABLE TO DRIVE IT. I ONLY GOT TO DRIVE MY CAR 4 MONTHS BEFORE IT WAS STUCK IN THE SHOP AND I STILL CONTINUE TO PAY FOR MY PERSONAL CAR MONTHLY. THE DEALERSHIP IS NOW ASKING ME TO PAY A "RENTAL" FEE FOR THE USE OF THEIR VEHICLE, AND IT HAS TAKEN 3 MONTHS TO FINALLY REPAIR MY VEHICLE, ALL BECAUSE THE MANUFACTURER GMC/BUICK WAS OUT OF STOCK OF A 2017 CAR PART. I HAVE TRIED TO RESOLVE THIS WITH THE MANUFACTURER AND HAVE A CASE# (SR:9-6454995176). I'VE BEEN IN CONTACT WITH THEM AND THE DEALERSHIP SINCE DEC 7, 2020.
