Known issues on the 2019 Acadia. Two recalls are recorded federally. One concerns tires that were over cured in manufacture and can break at the sidewall or separate at the belt edge, either of which can cost the driver control of the vehicle. The other concerns a start-stop accumulator endcap missing bolts, which lets transmission oil leak and can progress to a loss of propulsion. Owners have logged 381 complaints, the power train drawing 148, the electrical system 70 and steering 32. Transmission service, fluid leak diagnosis, wheel and tire specifications and the steering procedures behind those complaints are all set out in this manual.
