Latest 388 fuel system complaints
Problems with (after treatment)codes flashing, check engine, immediately went to stop engine immediately and truck shut off at 70mph. Fortunately not on incline or decline and was able to pull to safety. This happened on two separate occasions. Peterbilt nor cummins has not been able to diagnose the problem until the fuel pump completely failed and took out the engine. Manufacturer knows this is a design and engineering flaw and refuses to take responsibility for these older trucks that still have low miles but...

are out of warranty. We are personally aware of 5 engine failures in the same time frame of ours..All cummins isx15 motors. These engines are lemons. The after treatment engineering is a sham and the motors are not equipped to handle the strain. These are putting owner operators out of business and are an enormous safety hazard. What is the nhtsa prepared to do about this as the recall due to these fuel pumps should have spanned many more years and thousands more vehicles. Our issue started in 2016 not long after purchase through peterbilt and culminated with fuel pump failure/carbon packing this past week. We were told it was wiring harness and cummins was to cover the cost as no one seemed to be able to diagnose the issue. We have gone from being told it would be a 3800.00 Harness to being told that the truck needs a new motor and fuel/oil pump using the same flawed after treatment (this were the codes that had been appearing that could not be diagnosed, never warning for fuel pump, pressure issues, etc.) For an adtl cost of $39,000 in addition to the service work already performed to no avail. Owner operators cannot stay in business as manufacturers bask in the glory of sales and maintenance profits. Something has to be done. We have been in business for 12 years and now will go out of business and just hope we can sell this lemon. Act now.
