2005 Hyundai Tucson engine problems

Filed Feb 1, 2023 · Electrical, Engine · IA

This car accelerates while unattended. Most likely due to an ECM malfunction and unable to properly respond/send signals to the motor. On 4 occasions, the car has accelerated, even if in park. It will go 25mph on its own and to stop I had to put it in neutral. I’ve seen that my car isn’t the only one experiencing this. Considering it’s an ECM issue there should be a recall because that is not a part you change during the life of a car.

Initial issues on vehicle presented in january 2021 with various check engine light codes including p0133. Although vehicle passed emissions in 2020, various check engine codes for mass air flow sensor, oxygen sensors, misfire for various cylinders. After replacing indicated mass air flow sensor, oxygen sensors indicated via obd ii tool, battery, alternator (more than once), both front cv boots, head gasket seals for both cylinder banks, more check engine light issues appear according to the vehicle. Currently another cylinder misfire check engine code has appeared after all spark plugs have been replaced with oem recommended brand replacements (nkg pre-gapped spark plugs). The misfire code has cleared at this time. The current check engine code from the obd ii tool is error code for drive train driveability p0420 regarding catalyst system operating below threshold at bank 1. I have utilized local store catalytic cleaner liquids to clean the system, which has not resolved this issue. Additionally, beginning in january 2021, the vehicle was taken to the closest local dealship for a large majority of these repairs including a $150 dealership fee just to have these codes reviewed and additional fees for the labor to address for each issue for each repair.

The first time this happened I was pulling into a parking place in a shopping center. As I was turning into the parking place I very lightly tapped the accelerator and the engine reved up and I applied the brake only to have the car continue forward and go up the cement curb. I then pushed down on the brake pedal as hard as I could and only then did the car stop. If the cement block had not been there, I would have hit the car parked directly in front of me. The front tires had gone about two feet up on the cement block. The next time this happened I was once again parking. This time I was parking parallel to the curb. I pulled into and in front of the space I was going to park in. I put the car in reverse and began to back up slowly with my foot over the brake pedal. Suddenly, the engine reved up and the car lurched backward. This time I applied the brake very hard and I was able to stop my car before I hit car in back of me.

I was slowing to a stop and could feel that the car was going to die and it did. I took it to the dealer and they did a fuel induction service and it seemed to fix the problem.the dealer should have not charged me for a car so new, but they put under the service "maintenance" which I didn't find out till a couple years later when it happened again and I called the dealership. I have since had the same incident happen 5 times and after reading several people have had the same thing with no explanation I decided to put my incidents in so that more people would know it isn't just a single happening of the same thing. After this happens I take the car on the freeway and floor it meaning to blow out what I think may be stuck in the fuel line???? It always works for a while. This thing doesn't occur for any particular reason and I have the car well maintained. I now have over 120,000 miles and the last time it did this was about 6 months ago. Thank goodness nothing bad has happened because of it.

Engine on our 2005 hyundai tucson turned off in the middle of a busy highway going approximately 40 MPH. Managed to turn/roll off the road without power or power steering. Had to restart car several times as it would stall out on acceleration or when slowing to turn. Paid dealership $209 to "fix" the problem, but the problem still exists a month later and is getting progressively worse each day. Dealership did oil change, vehicle inspection and replaced "p0444 evap purge control valve connector." clearly this did not solve the problem as this severe safety hazard persists. Hyundai has no answers and several other similar complaints we've read have been filed with the federal safety agency. Something has got to be done.

Transmission keeps slipping out of gear when you put into gear and car won't move. You stop at a light and even though car is in gear it won't move. Flip it back and forth on auto gear shift sometimes it moves. Other times it changes gears or slips out.
