2011 Hyundai Sonata Problems

What owners report

Owners of this model year most often describe the engine stalling or losing power while driving, often with little or no warning. Engine knocking, rod bearing damage, and steering noises or loss of power assist are also common, and some owners report an airbag warning light that stays on. Oil consumption appears in a smaller group of complaints, and many reports involve mileage above about 100,000 miles.

   Engine

   Sudden stalling or loss of engine power while driving

   • 621 complaints (18%)
   • median 90,000 mi at 5.9 yrs old (489 state mileage)
   • 54 mention a crash, fire or injury
   • owner-quoted repair $3,177 (median of 49 quotes)
   • filed 2010–2026

   Owners describe the engine losing power or shutting off while driving, sometimes at highway speed, and in some cases the car would not restart and had to be towed. Some report warning lights such as the check engine, oil, or ABS light appearing just before or during the event, and others describe limp mode or a hesitation followed by a stop. Several complaints say the dealer or mechanic diagnosed internal engine damage, and some say the engine was replaced. Reports range from about 50,000 to 190,000 miles, with most between about 100,000 and 170,000 miles.

   What to check: Ask whether the engine was replaced or repaired under a recall, and ask for the diagnostic codes from any shop visit. On a test drive, check for hesitation, warning lights, and smooth acceleration at highway speed.

Most reports are at about 100,000 to 175,000 miles, with a few at around 60,000 miles.

   Recall 15V568000

   What to check: Listen for knocking on a cold startup and during acceleration on a test drive. Ask whether the engine has been inspected under recall 15V568000 and whether the crankshaft or rod bearings were replaced.

   “While exiting the freeway, my engine, eps, battery and oil lights all went on and my engine stalled out. This resulted in a tow to an auto repair shop, where I was told there was likely a rod bearing failure in the engine, which requires replacing the engine. After some research, I discovered active Hyundai recall 132 - engine inspection / replacement, which is very similar to what I experienced.this recall is not currently associated with my VIN, however, despite fitting the description and model years affected. Shouldn't I have been issued a recall notice for this?”

His friends and himself pushed the car into a radio station parking lot and had to finish walking back to campus. Ross said there was smoke coming from the engine compartment. The mechanic picked up the Sonata on the following monday. …”

Buying note. Ask for the engine repair and recall history, including any engine replacement under recall 15V568000, and confirm whether the steering and airbag recalls were completed. A pre-purchase inspection should include an engine stall and knocking check, plus a look at the oil level after a drive.
