The payload as listed on the vehicle certification label exceeds the actual limitations of the vehicle.  If the weight limitations of the vehicle are exceeded, the vehicle will not operate as designed, and may cause a safety issue. Owners will be sent a revised vehicle certification label that is accurate.

The Antilock brake system pump motor may have an insufficient spring clip installed, which may cause an internal bearing retention issue. This could affect pump motor operation, and may cause brake pressure differentiation issues between the front and rear brakes. Dealers will replace the brake pressure module valve assembly.

The brake pipe union fittings that feed the various brake system components may leak and cause a loss of braking function. Dealers will inspect the brake pipe union for signs of leaking brake fluid and replace the union if necessary.

I can assure you if you have a feul filter on the car with many miles the fuel filter can cause blockage and cause the vehicle to stall. To much E-85 fuel or fuel with the added ethenol can cause dirty and dripping injectors and you should change the fuel filter 25-30 thousand miles/2 years. Rule out the obvious lest expensive first. You will probaly do some needed PM.
