- the contact stated that while driving the 2002 Hyundai Sonata at 45 mph the vehicle lost power without warning. The contact was able to restart the vehicle after waiting approximately ten minutes. The vehicle was taken to a mechanic ,who advised the contact that the failure was due to the crank sensor, cam sensor, and the timing belt. The mechanic made the repairs. However, the same problem occurred the next day. The contact stated that the vehicle was then taken to the dealership, and they informed the contact the problem was due to the crank sensor, cam sensor and the timing belt. The dealership made the repairs however, the same problem continued to occur. The dealership then advised the contact that the module assy- timing and alarm system were faulty and needed to be replaced. The dealership repaired the module assy- timing and alarm system. The contact stated she has not had a problem with the vehicle since this replacement. The vehicle currently had 74000 miles.

With less than 1300 miles on the vehicle, it began to buck and surge in traffic at 65mph, and the tachometer began swinging wildly from 0 to 2500rpm. After getting off to the side of the road quickly, where it stalled again and again, I called Hyundai roadside assistance for a tow to the dealer. They examined and drove the car, and told me it wasn't acting up for them, and suggested I take it home while they ordered an exhaust purge valve per a 2. 4l engine problem service bulletin from Hyundai. While on the highway toward home, it began bucking and the tachometer was swinging wildly again, so I got off to the side, where it repeatedly stalled, and again I called Hyundai roadside assistance for a tow back to the dealer. They rented a car for me, and over the next week replaced the purge valve, but the car also died on them, so they did a more thorough analysis, which showed a failed crankshaft position sensor, which caused ignition spark failure. After replacing that, they called me to come get the car and take it home. This time it failed just as I reached my driveway, again bucking and stalling with the tachometer swinging wildly up and down. For a third time, I called roadside assistance for a tow to the dealer, which promised a search to determine the cause of the failures, involvement of the district manager, and an attempt to obtain a different sensor model in case the batch of available sensors was "bad". Subsequent phone calls to the dealership have not produced any answer as to the cause of the failures, delays in obtaining a suitable replacement part, and so far, a total of 18 inoperable days for my new car. This failure is a serious issue; a person at the dealership told me that "other (Hyundai) vehicles with the same engine had the same problem" one of which was there while I was at the dealer waiting for my second rental car. I repeat; this is a serious safety issue; such sudden loss of engine power in traffic can have fatal results!.
