Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“As far as I can determine there is no recall concerning tires on 2018 encores. Yet at only 19,334 miles on my Encore I had to replace a tire because the tire store could not get the tire repaired. Their comment was that the puncture on the tread area was too large to accept a patch. Thus I spent $172.25 for an equivalent new tire. If Buick is not capable of providing tires that will last past 19,000 miles then they need to do a quality check. The factory tire I had to replace was a continental tire (p215/ 55r/ 18 rated at 94h.”
NHTSA complaint #11324207, filed 2020-05, 19,334 miles“This took place on private property in the parking lot of a commercial building. The vehicle was in motion going forward. It was decelerating head-in into a parking spot. The braking action was engaged. The vehicle had slowed to about 5 MPH. My right foot was on the brake pedal and the braking was engaged. I then heard the sound of the engine revving at a very high rate. There was a high whining sound. I lost braking as my right foot depressed the pedal all the way to the floor. The car suddenly accelerated forward at an increased speed. …”
NHTSA complaint #11308591, filed 2020-02, 14,367 miles“The drivers side blind spot indicator is malfunctioning and giving false and erroneous indications this is due to the incorrect parts being installed at the factory. The dealership said that control module from the factory was the incorrect part number for the vehicle and may the cause of the problem, but they are unsure as they have been unable to replace it.”
NHTSA complaint #11088709, filed 2018-04, 256 miles“The driver's side blind spot indicator (located on the side mirror) is malfunctioning and giving false and erroneous indications - both false positives and false negatives - this has occurred each time I have driven the vehicle- on the freeway, on the highway, on side streets. If drivers depend on this extremely unreliable safety feature accidents are highly likely to result.”
NHTSA complaint #11099367, filed 2018-06, 150 miles“I was told to reach out to this site because of the issues I am having with my vehicle. I have been in a the process of trying to get my 2018 Buick bought back by GM. In june 2019 the Buick died on the railroad tracks in archie, mo then 30-40 seconds later it started back up on it's own without my assistance. I called on-star right away and asked if a code was thrown. No code was thrown. I drove it to the dealership. They found that the battery which was not even a year old blew up inside itself. I bought the Buick 8.24.2018. They dealership replaced the battery. …”
