General Motors has issued a major recall affecting 3.46 million pickup trucks and SUVs in the United States.
The defect: according to General Motors, the engine-driven vacuum pump in affected vehicles may lose power over time, resulting in reduced vacuum pressure and thus reduced braking performance. This problem was actually first brought to the public’s attention by Transport Canada, which issued a recall for about 300,000 affected vehicles in Canada earlier this year over the faulty pumps.
The hazards: GM says the braking performance in the vehicles may be reduced, but only in “rare circumstances.” If braking performance is reduced, the vehicle may require “increased brake pedal effort, leading to a hard brake pedal feel, and potentially increased stopping distance.” GM says it has linked 113 crashes and 13 injuries to the problem.

Affected parts: vacuum brake assist pump and electronic brake control module.
Number of affected vehicles: 3.46 million in the United States. GM previously issued a recall for 300,000 trucks in Canada for the same problem.
The fix: GM dealers will reprogram the electronic brake control module, which will improve how the system utilizes the brake boost assist when the vacuum pump assist is depleted.
