2011 Dodge Avenger Problems
RepairPal has identified the most common problems with the 2011 Dodge Avenger based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The anti-theft system may cause a no start condition due to electrostatic discharge (ESD) affecting the wireless control module (WCM). There is an updated WCM to correct this issue.
The automatic transmission can develop problems like erratic shifting, rough shifting, or delayed gear engagement. Repairs for many of these problems are outlined in service bulletins.
A knocking sound my be heard from the engine at times with the air conditioning on. The cause could be the AC compressor itself, if that is the case there is an updated AC compressor to correct this issue.
A weak or dead battery may be caused by the radio not powering down correctly. If the backlight is flickering every 20 seconds that would confirm the fault and the radio would need to be replaced.
The radio sound may mute intermittently and/or the temperature display may display a metric (Celsius) reading when the display indicates English (Fahrenheit). Both of these conditions can be corrected by updating the radio software.
The carpet under the right side of the dash may become wet with water. This can be caused by the AC evaporator drain being plugged with debris. Our technicians tell us that once the drain is clear, a cabin air filter should be installed to keep debris out.
Warm air only may be discharged from the AC system due to a faulty infrared temperature sensor.
A honk, hiss, or groan noise may be noted from the steering during low speed parking lot maneuvers. Our technicians tell us that replacing the power steering return hose may correct this concern, If it does not the steering rack and pinion may require replacement.
A defective vehicle speed sensor can cause problems with the cruise control and speedometer operation, as well as erratic shifting. The connectors on the sensors are also susceptible to corrosion, which will create similar symptoms. Any of these problems can cause Check Engine Light illumination.
