2016 HYUNDAI GENESIS with 240.0 miles

Sudden loss of power at freeway speed. Driving at freeway speed late at night with adaptive cruise control on, i accelerated and changed lanes to the left to avoid a collision with an inattentive driver. Immediately after changing lanes to the right to return to my lane, the car stopped responding to throttle input. Rpm gradually decreased to zero and the car stalled. No warning lights until the engine stopped at the right shoulder of the freeway. I restarted the engine. Still no warning lights. The car entered a limp-home mode with max rpm around 1500, very slow acceleration, max speed about 50 mph. It did not stall again during the 10 mile trip home. Towed to dealer. Dealer states that the obd2 fault code was P1230, low fuel pressure. The technician test drove the car and reproduced the behavior. Initial diagnosis was "failure of high-pressure fuel pump." today (5 days after incident) the dealer states that Hyundai tech support recommends additional diagnostics prior to replacing the fuel pump.

2003 SAAB 9-5 with 66500.0 miles

Car runs perfectly and at highway speeds will randomly stall. If you can manage to not get into an accident the car will start right back up after you turn off the key and restart. Sometimes every couple of miles, and can go several miles without the stall. Seems to only happen at constant speeds. This is a very dangerous problem. Diagnostic codes are P1230 and P1261, but i think these are results of the sudden stall, and not the problem. updated 03/10/09. *lj
