Default Good news, bad news.... "bullet-proof" Sonata breaks down

It was bound to happen, but the Sonata (2009 Limited V-6) lost all power on the drive to Chicago this morning... limped the 40 miles (at 22mph) I had to go to get back to the dealer.

Good news-
-only 40 miles to back track, could have happened in downtown Chicago, or yesterday while house-hunting with the family out on country roads
-limp-mode saves the engine in emergencies
- 1hr 10 mins to repair no cost

Bad news-
-it was a bad throttle sensors that went cruising at 74 mph with 22,076 miles on the car... wtf??? This cripples the car???
-Road side was 2+ hour wait... what if it was undriveable in -5 degree WI winter????
- Had to go back not even 10 minutes after leaving to readjust the idle after the software update
- Knowing (from personal experience) how cars suddenly develop reoccuring issues- what's next?

Will this FINALLY spurn me on to get that damn new car???

It happens. My GS has had 3 throttle position sensors replaced so far. All of them died on the highway, but at least it was able to limp itself home. Just be grateful you have warranty.

Always good to hear from actual owners with first hand report. But sorry about the inconvenience.

Stay spurned in the search!

Sales Manager sees me, walks up and says, "Hey Russ!!! Ready to get either the new Sonata or that Genesis?"

I said, "Dude, now is NOT the time to be talking about a new Hyundai..... especially since the meeting I am missing directly affects my purchase..."

He wisely ambled away with a "It's never a good time to have a car break down"... I heard that FOUR tiimes while I was there... obviously WELL REHEARSED!!!

IIRC, Hyundai contracts their roadside assistance through Cross Country Motor Club - the same guys who also have contracts with Geico/Ameriprise/Chrysler.

And with newer cars with DBW throttle and traction control, fail-safe is a given since there is no mechanical link to the throttle butterfly and the ECM cannot "gauge" how far the butterfly is opened - older cars with cable throttle can use MAF or MAP as a fail-safe if the TPS goes bad.

When you say limp home, how exactly do you mean?

that sucks. but it's better than a blown tranny on my acura cls. it happened to me an hour before my final exam. i stayed up 3 nights for that test. i did get a make up test though.


my worst ever stranded moment was driving with no engine oil on my vauxhall Carton 5 years ago. engine blew, and car got caught fire in the middle of london. there was no oil in the car!

The Limp-Mode, with most modern torque-converter automatics, usually means a locked second-gear, with no shifting. That generally allows stops/starts and relatively slow travel to the nearest repair shop....though starting in second gear can put some strain on the engine, especially starting on an uphill. This 2nd-gear limp-mode, of course, is not possible on non-torque converter automatics and automanuals like SMTs and DSGs, because they have no torque converter that allows internal slippage at a stop.
