Several auto recalls have been issued recalls over the last few months. Some of them have been for a small group of vehicles for safety issues while others encompass a mass group of vehicles from an automaker. Here are the biggest car, truck, and SUV recalls to hit the market recently.

GM SUVs And Trucks

A total of 3.5million 2014 to 2018 Cadillac, Chevy, and GMC SUVs and pickup trucks were recalled by GM (GM) for a vacuum pump issue. The recall affects the Cadillac Escalade, Chevrolet Tahoe, Chevrolet Suburban, Chevrolet Silverado, GMC Yukon, and GMC Sierra models.

According to GM, the vacuum pump may output lower power, which could reduce the vehicles’ braking force, increasing the risk of a crash.

To remedy the issue, dealers will reprogram the electronic brake control module.

Nissan And Infiniti Car, Trucks, SUVs, And Vans

Nissan (NSANY) has recalled 1.2 million 2018 to 2019 cars, trucks, SUVs, and vans sold under the Nissan and Infiniti brands. The recall affects the Nissan Altima, Frontier, Kicks, Leaf, Maxima, Murano, NV, NV200, Pathfinder, Rogue, Rogue Sport, Sentra, Titan, Versa Note, and Versa Sedan models as well as the Infiniti Q50, Q60, QX30, and QX80 vehicles and the Nissan GT-R and Taxi models.

The recall was issued because the vehicles’ backup camera may not display an image, which is a safety violation that could increase the risk of a crash.

To fix the issue, dealers will update the camera software on the vehicles.

Dodge Ram Pickup Trucks

Fiat Chrysler Automobiles (FCAU) has recalled Dodge 693,000 2013 to 2014 Dodge Ram pickup trucks. The recall affects certain Ram 1500, 2500, and 3500 models. This is an expanded recall from Dodge’s May recall for power locking tailgates that may open when driving because of the actuator limiter tabs may fracture.

The recall adds to the 1.1 million Ram trucks that were recalled over the same issue in 2018 as well as the 410,000 vehicles that were recalled in May.

To repair the tailgate issue, dealers will fix the tailgate latch.

Ford And Lincoln Pickup Trucks And SUVs

Ford (F) has recalled 560,000 2018 to 2020 F-150, 2019 to 2020 F-Series Super Duty, 2018 to 2019 Explorer, 2019 to 2020 Expedition, 2020 Escape, and 2020 Lincoln Aviator vehicles. The recalled trucks and SUVs may be missing a third pawl that provides seatback strength, which could cause the seatback to inadequately restrain an occupant during a crash.

To repair the issue, dealers will inspect the seat structure and will replace it if required.

Ford SUVs

Ford has recalled 312,000 2017 Explorer SUVs with power front seats. The recall was issued because the seat frames may have improperly coined edges, which could cause a hand injury when reaching between the seat and the center console of the vehicle.

To resolve the issue, Ford will add flocked tape to the exposed edge and tab of the seat frames.

Chevy Cars

Chevy has recalled 177,000 2018 Malibu sedans because of an engine control module software error. The error could cause the car’s fuel injectors to disable, preventing the engine from starting or causing it to stall.

The fuel injector issue will be repaired by dealers by reprogramming the engine control module’s software.

Ford And Lincoln Cars And SUVs

Ford has also issued a recall for 90,66 2013 to 2016 Fusion, 2013 to 2016 Lincoln MKZ, 2015 to 2016 Edge, and 2016 Lincoln MKX models. The automaker issued the recall because, in some U.S. and Canadian regions, the vehicles may experience corrosion of the steering gear motor attachment bolts, which could cause them to come loose or detach from the gear housing. The vehicles did not receive the proper wax coating, Ford said.

The issue will be repaired by dealers by replacing the steering gear motor attachment bolts and by applying a wax sealer to the assembly.

Shares of General Motors stock was down 0.34 percent as of 1:15 p.m. ET on Friday while shares of Nissan stock were up 0.57 percent at the same time. Shares of Fiat Chrysler stock were down 1.16 percent and shares of Ford stock were up 0.17 percent at the same time.
