general problems of the 2009 Hyundai Elantra

Tl the contact owns a 2009 Hyundai Elantra. The contact stated that the vehicle accelerated when the gear was placed in reverse. When the brake pedal was applied, the vehicle surged to an unknown high rate of speed. When placed in neutral, the vehicle failed to decelerate. As a result, the contact sideswiped another vehicle. A police report was not filed. The driver was not injured. A dealer was not contacted. The vehicle was parked at the contact's residence due to the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The VIN was not available. The approximate failure mileage was 120,000.

Engine start vibrating at low speed.

When going around curves more than 35 mph the car will start decelerating (as if it's braking on its own without me engaging the braking system)and the esc light illuminates on dash. Also the exhaust makes a popping noise after engine is shut off which cause a powertrain issue because the vehicle is not accerrating properly. I personally know someone that has the same exact vehicle and that customer experiences the same issue.

I have 2009 Elantra, September 2017 I noticed a lag in the shifting always at 25-32mph most of the time I had to remove my foot from accelerator to manually shift. Whether I �manually shifted� or stayed on the accelerator, there would always be a hard jerk during the shifting of that gear. On deaccereration, the car would always jerk on the downshift almost always at the same 25-32mph. I had to avoid highways due to safety concerns of merging due to the lack of acceleration. I decided to have the transmission serviced at a Hyundai dealer. The day I picked my car up, I couldn't drive over parking lot speeds. I immediately drove it to the dealership I purchased an extended service warranty through and my transmission was replaced with a used Elantra transmission with 72,000miles. The car shifted great for first 2months, now second transmission has been doing the exact same thing as original transmission. I have not reached out to service warranty company as it will just be a waste of time and effort. I can't afford to be without transportation for 5-7days and they do not offer rental or loaner car, just to get yet another used transmission just to have the problem reoccur. I would like Hyundai's assistance to get a new transmission that will reduce safety issues and prolong the life of the car.

Receive service campaign notification to apply rust-proofing materials to underbody to arrest the corrosion process. Took car to local Hyundai dealer for rust-proofing and was informed that the oil pan is rusted and needs replaced at a cost to me over $600 - I have written estimate from Hyundai dealer. Informed that oil pan needs replaced because if it fails that oil will leak out and damage\ruin engine. Told Hyundai would not cover oil pan replacement under warranty as I am not the original owner even though mileage was under 100,000 at time of service. If I was the original owner, then it would have been covered under the 100,000 mile bumper to bumper coverage. I also have a 2010 Hyundai Elantra that received same service campaign notice for rust proofing underbody and oil pan is looking its like heading into same direction in need of replacement due to rust. This should not be happening to the oil pan even after 10 years of age.

The contact owns a 2009 Hyundai Elantra. While driving approximately 35 mph, the transmission exhibited hesitation. The failure recurred numerous times. The vehicle was taken to the dealer who flushed the transmission. The failure persisted after the service was performed. In addition, the horn failed to operate intermittently. The vehicle was not repaired. The manufacturer was notified. The approximate failure mileage was 20,000.

I have a consistent problem with shifting gears. This has been going on for a few years. I'll try to take off and it feels like it gets stuck between the lower gears. It causes the car and occupants to get jerked around strongly. A few times it has made it difficult to proceed through an intersection. Hyundai dealer states it is the "speed sensors", but no longer covered under warranty.
