7: Chevrolet Impala
The Impala is a noteworthy sedan and one of the longest-running GM nameplates of all time. But there have been many issues with this car in recent years. GM build quality isn’t what it once was, and this is the case with the Impala (via Motor 1).
The overheating issues that plague these cars are just one of the most common issues you’ll encounter. There are also issues with the transmission, and more recently a faulty brake system was covered under a recall.
