| Diesel Fuel System problems |
I have a 2013 navistar Prostar that I've had to take into the dealer for various repairs. Currently, I have experienced a problem with the diesel exhaust entering the cab that has caused my eyes to burn, a lack of strength and other health issues that according to my doctor, I should not be driving until the problem is resolved. The dealer has offered little or no assistance claiming they will have to remove the cab to inspect the exhaust. Also, I have a problem with the cruise control not slowing the truck down when going over a hill. I have to tap the brakes in order deactivate the system and then use the jakes brake and regular brake to slow the truck donw.
There are more affected parts than this allows me to select. Doors automatically lock intermittently while parked. Window does not close properly very poor fuel economy, average mpg around 5. 2mpg many many coolant leaks fuel leaks oil leaks engine has just taken of and given a small boost in speed while in parking lot at 5 mph after idling over night. Electronic gauges not working occasionally leveling valve constantly loosing adjustment on the suspension. Jack breaks are constantly not working up to par. Gas peddle extremely hot temp. Aprox 160 degrees. Took delivery of the truck end of oct. 2012 with 1800 miles on it. It has been in the shop 100 to 130 days total as of today, 1/7/14 for all of the same issues over and over again.
