Known Problems

The turbocharger return pipe seal may develop an oil leak. The leak can begin very small, but will eventually progress into a large leak. Our technicians recommend having this repaired at first signs of leakage.

The Volvo S40 from 2011-2012 is known to have issues with hard shifts and transmission slippage on models equipped with the six speed automatic transmission. When the transmission gets warm, the issues is most noticeable as a hesitation to shift, followed by jerking or jolting into the next gear.

The hard shifting and transmission slipping is commonly a result of software inadequacies, which do not account for all variables as the transmission heats to normal operating conditions. In some cases, the automatic transmission may be suffering from a damaged valve body or faulty shift solenoids.

Software updates from the manufacturer of this transmission have solved many reported complaints, but not all. In cases where software updates to the transmission controller have failed, the transmission will likely need valve body replacement, shift solenoid testing and replacement, or even a complete rebuild.

Since the transmission is sealed for life, the fluid is not normally considered a suspected cause, but many technicians recommend changing the transmission specific automatic transmission fluid at normal intervals. 

 

The engine may not start due to a failed starter control module. If the module has indeed failed, it will require replacement.

The right front engine mount wears out prematurely, causing engine vibration at idle.

There have been reports of premature rear brake pad wear. Our technicians recommend to inspect brake pads at each tire rotation interval.

The fuel pressure regulator can leak and cause a hard start condition, without any faults recorded in the engine computer.
