My hood won't release 2006 sonata - 2006 Hyundai Sonata

There are a few ideas here. The car shouldn't start in neutral, it should only start in Park and with foot on the brake. The are a number of sensors, switches and modules that make this happen. Take it to the dealership.

If you're comfy with manuals then i know few websites that can help you with it. Bcause I've got it from various websites so I know how each
site deals. try www.reliable-store com . Very helpful

Have someone push down on the hood over the hood latch area while you pull the release, that may work. Once it is open lube everything up with white Lithium grease also known as "LUBRIPLATE:"

If you are looking to open the hood of an Infiniti QX56, look for a lever somewhere on the side of the steering wheel or by the driver's side door. --------------------------------------------------------------------------------

ya i recently had my battery go bad on me. 06 sonata is @ 58k. previous to the battery issue had noted as irritating and strange as it is that my hood latch was not releasing, so after a tow to the shop and a 3 day rental...parts and labor was over$500. the very nxt week even tho i asked them to take a look as id had the ESC off light illuminiate vry sporadically recently. was "noted and light is off now" by the shop. 3 days out of shop light on again....back in shop a week after first. now i'm being told the entire ESC electronics system needs to be replaced at just under $600. i am starting to suspect i shud have gone w a honda.

Check with Dealer - unit may have to be reset after the power to it was interrupted during the changeover you alluded to.

bad switch or plug also check flash relay may have bad connection

look under the hood to see if there is any thing block the shift cable and linkage.

the salvage yard or dealer ship

I had to reinstall the loose mounting hardware for the trunk upper latch.
