P0605 on HYUNDAI SONATA
What P0605 Means on Your HYUNDAI SONATA
Real HYUNDAI SONATA Owner Reports (Source: NHTSA Complaints Database)
"My husband and i are the owners of two 2011 hyundai sonatas. our complaint is based on the fact that we feel that hyundai has either purposely or in ignorance created an inherent defect in its battery system."
"Reconnecting the battery after servicing the car the vehicle gets a check engine light p0106 code (p0106 manifold absolute pressure/barometric pressure circuit range/performance). the engine runs normal."
"During cold weather, the 2.0 turbo sonata engine will cut power to the car and go into a "limp" mode if an over boost code (usually p0605 & p2110 ), is triggered. this causes an unsafe situation as there is very little power available to get out of the way or can cause a rear vehicle crash."
"Purchased car with just under 97000 miles. Was working terrific. Time for the first oil change and 2 miles after the change the car froze and went limp. Traveling 45 miles per hour it recorded a trouble code on my monitoring device. P0605 - ROM error and the car was dead."
