Recalls for the 2019 Chevrolet Blazer: 2
The affected tires were cured for too long during production. Over cured tires may develop a break in the sidewall resulting in sudden air loss or a belt edge separation which could lead to a tread/belt loss. Either condition can cause a loss of vehicle control, increasing the risk of a crash.
The start/stop accumulator endcap may have missing bolts. Missing bolts on the start-stop accumulator endcap could result in a transmission oil leak and may progress to a loss of propulsion, increasing the risk of a crash.
