Chevrolet Impala Common Problems
Regardless of how well you take care of your vehicle, issues may crop up as it puts on mileage. Here are some of the most common Impala problems per model year:
Transmission Failure
Transmission problems have been reported in some units of the 2011 Chevy Impala. Owners report hearing a loud noise from the transmission before it failed. They also noticed stuttering and jerking as their vehicles slowed down.
Similar problems have also been reported in some 2005 and 2006 models. Steer clear of units that have slipping transmissions and have difficulty shifting gears.
An Impala with a serious transmission problem may need to have its entire transmission replaced or rebuilt. Repair work for this type of problem may cost as much as $2,970.
Power Lock Malfunction
Power lock problems have been reported in some units of the 2008 Chevy Impala. Their locks may work intermittently or fail to operate completely. Replacing faulty components like the lock assembly, actuator, or sensor appeared to solve the issue in most affected vehicles.
Heater Issues
Some 2007 Chevrolet Impalas have had problems with the operation of their heater. One owner said his heater suddenly stopped working because of clogged lines. Mechanics speculate that low-quality antifreeze may have caused the issue.
Several owners also noticed cold air blowing from the heater vents while their vehicles were on idle. There are many possible causes for heater malfunction. Some owners had to replace their faulty thermostat, while others had to have their head gasket leak fixed.
Some owners also noticed a weird smell coming from their A/C and/or heater vents. One owner attempted to solve the issue by having his Impala detailed, but it didn’t solve the issue.
Excessive Oil Consumption
Some 2006 Impala owners have also had problems with their engine’s excessive oil consumption. Drivers report not noticing any visible oil leaks, which suggests that the engine was burning it.
Replacing the oil pan is a common fix for this issue.
Passlock Issues
Passlock problems have been reported in some units of the 2002 Impala. Owners were upset about getting locked out of their vehicle, their check engine and security lights going on and off, and experiencing difficulty starting their vehicle.
Passlock system issues can be complicated, so it’s best to have a professional diagnose the problem. Replacing the body control module or bypassing the ignition sensor appeared to solve the issue on most affected vehicles. Repairs for this type of issue can cost as much as $520.
Intake Manifold Gasket Failure
Some 2002 Chevrolet Impalas have suffered from coolant leaks due to a bad intake manifold gasket. This causes frequent overheating, which may result in more serious engine problems. This problem may recur, and some owners had to replace their intake manifold gasket more than once. You may spend as much as $820 to fix this type of issue.
As long as you’re aware of the potential issues you may encounter with an Impala, buying this vehicle should come with little risk. Do your research and make sure to clear everything with the seller or dealership before finalizing your purchase.
