Car hesitated, sputtered and lost power. Dealer could not initially diagnose cause. Hyundai engineers became involved. Replaced engine wiring harness which resolved issue to date.
high pressure fuel pump leaked due to failed bolt. They replaced bolt and seal
The "cam Sensor" failed causing the engine to run poorly.
Excessive valve clatter unless I use premium fuel. Unable to fix because there is "no error code" It's starting to look like Hyundai makes it very difficult for dealerships to get reimbursed for troubleshooting problems.
Engine quit on highway, dealer found no problem first time, engine died a few days later in slow moving traffic. Dealer replaced ECM unit. Car since stalled out again so I guess it's not the ECM?
Car stalled again after dealer reprogrammed the PCM. Dealership replaced the electronic throttle system. All seems well. Dealer also performed an alignment at this service as the car pulls to the left.
Noticed a burning smell after a long highway drive in very cold weather. Dealer found an oil leak and replaced the valve cover and gasket moulding.

Check Engine light came on. Dealer said it was a vacuum leak (probably gas cap) and reset the check engine light. I had filled by tank two days before and had driven over 200 miles before the check engine light came on? Wait for fix??
Metal shavings in the engine, engine was rebuilt.
The engine blew. It needs to be replaced. Approx 5 weeks ago Hyundai sent me a notice they were extending my warranty by 20K miles because of possible piston problems. Well driving home from the store the motor blew. No warning lights.
The car was cranking a long time before turning over and running rough, with hesitations, loss of power, and trouble shifting (Auto Transmission). The Dealer said the symptoms matched a TSB and a software update would fix it.
After the previous repair attempt, the problem returned in one day: extended cranking, rough running, hesitation, loss of power, trouble shifting.

B1S2 O2 sensor replaced.
Fuel cap needed replacement. CEL light came back on after only 500 miles. Will be heading back to dealer for diagnosis.
The CEL is still intermittent, I believe it's still the fuel cap. The problem was never fully resolved. It's not on right know (knock wood) and hopefully it stays off!

replaced oxygen sensor under factory warranty
Going down the highway and heard a thump from underneath the car. Did not run over anything. Went to the service department and explained what happened. They performed ecm update.
Originally O2 sensor was bad. Then they told me the catalytic converter was cracked. Repair ordered suggests that they might have damaged it replacing the sensor. Also brake fluid change.
Engine unusually noisy under load -- a type of clattering sound. I suspect pre-detonation, but dealer says sound is normal.
Coolant in ovrflow container continued to lose fluid. Dealer tech said lower coolant hose was pinched, he re-positioned it. Over a yr. later, STILL losing coolant on 5/23/13 at 39301 miles. This time tech discovered "oil cooler tube" was split. Part # 25470-2G000 replaced under warranty. No further problems.

intermittent 'limp-home' mode and intermittent 'check engine' light. Dealer replaced the throttle body assembly (warranty).
Check engine light came on, second o2 sensor on cat. converter failed, replaced under warrantee
Fuel backed up when filling even less than a gallon. El Paso Hyundai replaced a sensor near the fill line. Some relief but still premature click off at the fuel nozzle. Lakeland FL worked with factory.Obstruction in fuel line (webs)
Putting fuel into tank still causes multiple click-offs of nozzle. BUT, it does not give an error code. I have been videoing my fillups; only happens some of the time.
Unable to add fuel. Hose would click off within adding a gallon of fuel.
Fuel smell narrowed down to between ports 2 and 3. Pulled the intake - the groove for the intake gasket on port 3 is warped, gasket doesn't seal, thus a minor fuel leak. Replaced gasket, problem still persists. Fuel smell under the hood and inside when the car is stopped at the red light. Could smell it around the car after shutting engine off. 3 visits to the dealer (Richmond Hill Hyundai) said no problem, washed the engine, problem persists Pulled the intake again, applied Permatex gas-resistant high-temp silicone around the gasket. Fuel smell is almost gone, at acceptable level now - cannot smell it inside or outside. Ideally need to replace the intake - an $800 part.
Difficult to put gas in tank. Nozzles would keep shutting off. Told debris in filler neck. Repair attempt unsuccessful. Makes getting gas time consuming
Ignition switch was failing. Starter would stick in start position. Easy repair, $35 dealer part.
Auto Transmission was repaired in early October. It shuddered and vibrated at between 40-60 miles/h. TCM was updated but didn't resolve the issue but improved shifting quality. Made another appointment to check it up at the end of October.
The problem only occurred when the engine was cold or parked for a long time. I could not replicate the problem and when I explained them what was going on, they said they couldn't fix it unless they see the problem.
Hard downshift on stopping. Reprogrammed chip for transmission. Perfect fix. No further problems.

New car, in shop for 32 days with 285 miles. Electrical problems first manifested by trans. shift lock not releasing. Modules, brake switches, main fuse box, and main wiring harness replaced. Proceeding with Lemon Law procedures as the car is not "NEW
Ignition cylinder would not function-- steering wheel locked. New key cylinder installed.
Oil leak from timing chain cover. Replaced seal.
Dealer repair service stated that the serpentine belt was cracking and should be replaced. I questioned because mileage was low but they maintained that 5 years is life cycle for such a belt. I asked to save the used one and give it to me.
Knocking or Pinging of the Valves when accelerating.
gas mpg dropped by 15+ per cent in last 4 months. cleaned fuel injection system.
Key frequently sticks in the ignition and will not turn. Multiple inquiries have produced various possible solutions. O manual says to turn steering wheel and key simultaneously. Locksmith says to clean with Ballistol. Not happy.

A flap or gasket was not opening properly to let air out so engine can turn over. They replaced it. I can't remember the exact price but it was over $300
needed left bank o2 sensor replaced. Also need to check suspension
the engine was missing
Check engine light came on. Warranty repair- camshaft position sensor indicated overadvanced timing. Corrected.
Check engine light, oil pressure regulator faulty, replaced. Transmission was not going into "OD" (torque converter lockup)and mileage dropped noticeably as a result. Transmission was reprogrammed preventing former premature "lockup" condition since new and OD seems to be working correctly again
Since new, car prematurely upshifted into OD, causing engine lugging, poor throttle response and an objectionably loud booming sound within the cabin. Reprogramming the shift point almost eliminated these issues, netting better overall mpg
Fuel pump was too weak to start vehicle. Pump needed replacement, and car needed to be towed to dealer.
During safety inspection, it was determined that the car needed an exhaust pipe.
