I have a 2015 Hyundai Sonata with 24K miles. The check engine light came on and was flashing as I pulled into a parking lot for my daughter to pickup her car. The garage owner said to pull in my car. The diagnostic read out was P2600 obs-ll. Upon researching it the code said, coolant pump "a" control circuit?open. They provided me with the print out. They said try to drive it. I did & drove maybe 300 feet & it would not accelralte above 15 mph. I turned around took it back to the garage's lot. The next day I called Hyundai roadside assist to have it towed to superior Hyundai South, where I purchased the car.this occurred Thursday January 17th. The car is still at superior Hyundai waiting word from Hyundai motors. Dave the service manager said it either needs a wire harness or an engine. Not sure the relationship. Seems to me they should put on the wire harness, if that doesn't fix it replace the engine.

Cylinder 4 went bad at 113,000 miles. Out of warranty, Hyundai did decide to cover the cost of a new engine. This happened on 8-10-18 and the vehicle has still not been repaired. Hyundai has stated that the engine is on back order and could be the 1st week of January 2019 and possibly later before the engine is available. I have heard from the dealer that there are close to 10,000 Hyundai 2.0T engines that are needing replaced for the same issue. So far 4 months of car payments and car insurance being paid on a vehicle that cannot be driven.

On Friday October 12. 2018, I was driving on the 78 high East bound and was about to pass another car. As my car was accelerated, the car engine lost power. The engine check light came on. My car was decelerated. I was lucky because the traffic on the freeway was light. I was able to move the car slowly to the emergency parking area and stop the car. I have a car computer diagnostic device and hooked it to the car computer. The device read an error code P1326_ glow relay stuck on the car was towed to the nearest Hyundai dealer. So far the dealer service department has not told me what wrong with my car and how they fix my car..

I took my car to priorty Hyundai because it wouldn't start. They said it was a issue and then priorty Hyundai fixed it and let me drive it. 3 weeks later it did not start. They say they fixed it but now they are telling me to tow it to them so they can check it. They say a recall has been issued. And I have to wait 5 days until the check it. I am missing work.

It stopped once when I was in the highway coming back luckily traffic went around me until it started and I was able to get home. Now it doesn't start.

This car has received regular oil change including filter changes and the engine has been flushed twice because each time the oil change miles have occurred the oil in the engine appears to be muddy. This car is only being driven to and from local city limits and only has 65,000. The car started braking down slowly with no explanation. 1st battery died constantly we put in a new battery, then the starter failed we replaced with brand new starter now the engine is completely gone. All in a matter of one month. Based on all the 1,000 complaints I have read on this particular car, all have experienced the same thing. Please this needs to be investigated

Purchased car and have had 3 recalls already. Car has need at dealership for a month now and they are unable to update when it will be available and what will be done to it. Also I checked the VIN number on VIN check pro and it show the car as branded on 1/30/2017 in Texas as salvage. It also shows branded on 04/25/2017 in Texas as junk. They Hyundai corporate office says they do show this on thier records. Could you please help because at this point I do not feel the car is safe for my daughter to drive. After the last recall was complete, the first time the car was driven the check engine light started flashing and the car had little power. It has been a T the dealership since then.

Sonata

  • 42,000 miles
To note vehicle had a complete evaluation 1 week prior with no current or upcoming issues. Upon starting car "ABS light, traction light, bsd (blind side detection) light" came on. Upon driving, my bsd sensors did not operate, and engine made whistling sound upon acceleration and would not go over 40mph without the power being pulled from the engine. Also to note my car was apparently trying to be in a higher gear at 30mph (5th gear). All of this is very suspicious as the car has only been serviced at dealerships with most recent being 1 week prior. Service department seemed very poor at explaining the cause for the simultaneous malfunctions of all these systems. I do not currently feel as safe with this vehicle as I have before.
