Porsche will be contacting the owners of certain 2015 918 Spyder vehicles, regarding a problem that could increase the risk of a crash. An analysis of a single observation in the field revealed that the lower control arms of the front axle may contain a manufacturing error at the ball joint. Due to variations of the surface coating processes, components and some of the underlying material may have been left unprotected, potentially leading to cathodic stress corrosion cracking (SCC). The problem could affect vehicle handling and increase the risk of a crash.

Porsche will notify owners, and dealers will replace the lower control arms. Owners wanting more information about the problem are asked to contact Porsche customer service at 1-800-767-7243. Porsche’s number for this recall is AG09 and the NHTSA campaign number is 16V-885.

Mercedes-Benz (MBUSA) will be contacting the owners of certain 2017 E400 4Matic Coupe, E400 Convertible, E550 Coupe and E550 Convertible vehicles, because one of the under body panels may have been manufactured out of specification. Vehicles equipped with dual exhaust systems may not have enough clearance between the catalyst and the panel. High temperatures could melt the panel and under certain conditions result in a fire.

Dealers will inspect and replace the under body panel, as necessary. Owners wanting more information about the problem are asked to contact Mercedes customer service at 1-800-367-6372. The NHTSA campaign number for this recall is 16V-831.

Mercedes-Benz will be contacting the owners of certain 2016-2017 Mercedes Benz S63 AMG, S65 AMG and S550 coupe/convertible vehicles because the seat belt extender may not retract as intended. According to the defect report, the control unit for a specific production range was not properly coded to account for friction conditions during activation of the extender. In the event of a crash, the extended seat belt extender could break, minimizing the full protection of the seat belt and may create edges that could inflict additional injuries.

MBUSA will notify owners, and dealers will update the control unit software. The recall is expected to begin in mid-December 2016. Owners wanting more information about the problem are asked to contact MBUSA customer service at 1-800-367-6372. The NHTSA campaign number for this recall is 16V-829.

Chrysler will be contacting the owners of certain 2017 Jeep Wrangler vehicles regarding a problem affecting the fuel system. The affected vehicles may have been assembled with a fuel tank that has a cracked or broken control valve. The problem could result in a fuel leak during a rollover event, debris in the fuel tank and/or the potential of over fueling the vehicle. A fuel leak in the presence of an ignition source can increase the risk of a fire.

Jeep dealers will inspect the fuel tank and replace fuel tank and sending unit as necessary. Owners wanting more information about the problem are asked to contact Chrysler customer service at 1-800-853-1403. Chrysler’s number for this recall is S90 and the NHTSA campaign number is 16V-849.

General Motors will be contacting the owners of certain 2017 Cadillac XTSs and 2017 GMC Acadias regarding a problem affecting the brake system. An investigation into the subject vehicles found that the supplier of the brake caliper assembly may have incorrectly oversized the front caliper piston bore during machining. The oversized bore could prevent proper compression, allow the seal to extrude between the piston and the bore, and could result in a brake fluid leak. Drivers may experience reduced braking and/or an illuminated brake warning light.

Dealers will inspect the front brake calipers, replacing the assemblies as necessary. Owners wanting more information about the problem are asked to contact GM customer service at 1-800-458-8006 (Cadillac), or 1-800-462-8782 (GMC). GM’s number for this recall is 16096 and the NHTSA campaign number is 16V-8020.

The owners of certain 2016 Nissan Titan Diesel XD trucks may experience problems with their fuel readings due to a manufacturing error affecting the fuel tank ventilation. During the assembly process, certain technicians may not have removed the temporary fuel tank breather tube cap and failed to affix the tube to the bed rail. As a result, the fuel tank may not receive proper ventilation and in rare instances may deform. This condition could result in the fuel gauge and the distance to empty meter displaying inaccurately.

Dealers will inspect the fuel tank breather tube, replacing the fuel tank, fuel sending unit, and/or fuel tank breather tube, as necessary. Owners wanting more information about the problem are asked to contact Nissan customer service at 1-800-647-7261. The NHTSA campaign number for this recall is 16V-847.
