BMW has expanded its list of recalled vehicles after receiving complaints about driveshaft problems in X5 and X6 SUVs. The auto company, which recalled about 21,000 vehicles for similar issues in 2016, added another 134,000 automobiles to the recall list, according to reports.

The expanded recall affects X5 and X6 models made between 2011 and 2014 suffering from broken driveshaft joints that can cause the SUVs to stop moving. Only vehicles sold in the U.S. and Canada were affected by the recall.

Some vehicles may develop a small leak in the power braking system, which could result in vacuum loss and inevitably cause the power braking to fail, BMW said in a statement. However, drivers will still be able to depend on mechanical braking to slow and stop the automobile.

The automaker said leaks in the power braking system could have stemmed from defective universal joint seals that weren’t manufactured properly.

BMW asked any drivers who have experienced problems or reduced power braking assistance to schedule a service appointment with certified BMW Centers to have the driveshaft replaced for the following vehicles:

V8 and V12-powered X Series including X5 and X6 models; 5 Series; 6 Series; 7 Series; BMW Alpina B7; or Rolls-Royce Motor Cars produced between 2002 and 2010.

While no monetary refund will be offered to owners of vehicles with a faulty driveshaft, BMW has said it would offer a full front driveshaft replacement at no cost. Replacements will be issued starting April 24 after the company has distributed the necessary parts to all Authorized BMW Centers in the U.S. and Canada.

BMW car owners will also receive a First Class letter from BMW asking them to schedule an appointment at an Authorized BMW Center once the service centers receive the necessary parts. Car owners can also check to see if their automobile is affected by the recall by checking their vehicle's VIN number on BMW’s website.

No car crashes or injuries related to the driveshaft joints have been reported.
