2001 Hyundai Sonata Owner Comments

problem #4

Sonata 4-cyl

Hyundai Sonata 2011 push button start. I am the original owner of the vehicle. Yesterday I went into my car and proceeded to start my car. I had to push the start button three times before actually started up. This happened twice within 2 hours. 5 days prior my vehicle had been to the Hyundai dealership for the recall on the stop lamp switch. An existing recall (NHTSA campaign number: 13V113000) indicates that for the 2011 Hyundai Sonata the stop lamp switch may not function correctly. They, the dealership, performed the service and replaced the stoplamp switch. As result my car is experiencing intermittent switch point contact with the push-button start feature. This is crazy.

I am the owner of a 2001 Hyundai Sonata gls V6. As I was coasting down the exit ramp of an interstate highway, approach a stop light, my car suddenly began to accelerate uncontrollably. I was able to stop only by applying the brake with considerable force, barely avoiding a collision with cars stopped at the light. I then shifted from drive to neutral. The engine began alternately revving up to beyond 3,000 RPM and back down to idle repeatedly. This stopped after turning the engine off and restarting. It happened twice more at succeeding stop lights. The car was towed to the dealer. They repaired it by replacing the transmission range switch-inhibitor (part no. 42700-39050). According to the dealer, this is a known defect covered by service bulletin tsb 03-40-013. While I managed to avert an accident, this was a very serious failure that could have resulted in injury or death. I feel very strongly that this should be the subject of a mandatory recall.

Engine misses and backfires through the intake. The major problem is when the engine is running and it doesn't matter if it is in park, or if you are driving it. I was on my way to work when it malfunctioned. I was sitting at a signal light when the engine accelerator went up to 4200 RPM by itself with no foot on the pedal. I almost got into an accident, I pressed harder on the brake pedal and had to take it out of drive to avoid hitting the car in front of me. The engines rpms change a lot now and will not idle right at all; this car is not safe to drive with these engine problems; and should not be on the highway. I had a Pennsylvania certified inspection mechanic look at and drive the car; and he said the car is not safe to drive; and if it would have been due for state inspection that it would have not passed; but failed and would be illegal to drive.
