Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“When I go 63 miles an hour the car starts chugging and my dealership changed the transmission fluid. I drove it home today and it still chugging. They called me and said they took a 2026 Buick encore and did the same thing but will not help me. They told me it’s a daily occurrence in the vehicle. It shouldn’t be chugging going up hills at 63 miles an hour.”
