Known Problems

The automatic transmission may develop shifting problems and/or the Check Engine Light may illuminate due to internal component failure and/or software issues. It is always best to be sure the transmission control module has the latest software installed when any major transmission repair is performed.

The front control arm bushings wear out, resulting in alignment issues and squeaking and/or knocking noises from the front end. Worn bushings will require replacement.

 

Many complaints have been reported regarding Volvo S80 transmission shifting issues. Long shift times between gear shifts, hard shifting, hard downshifting and a loss of transmission operation all together to name a few.

If the issue is minor, a transmission software update may address this issue so if available, the software should be updated before any repairs are made. After a software update or repair, the shift adaptation needs to be reset. A good quality Volvo repair shop will know how to perform this task.

There are several technical service bulletins (TSB's) available from Volvo that address these shifting issues and they should be consulted by the repair shop during the automatic transmission diagnostic process.

Regular servicing of the transmission fluid can help with preventing transmission failure, but not in all cases. Follow the suggested fluid replacement interval recommended by Volvo. You will find this in your owners manual, or find it here: http://bit.ly/Volvo_Owners_Manuals

Front upper strut mounts may wear prematurely, resulting in loud noise from the front of the vehicle when going over bumps.

Engine oil leaks from the PCV housing and turbocharger oil return line seals have been reported.

The Electronic Throttle Module (ETM) has a higher than normal failure rate. Volvo has extended the warranty on some of the ETMs to 10 years/200,000 miles

Transmission issues related to shifting have been reported. Software upgrades available from Volvo often resolve these problems.
Several software related issues have been reported and it is recommended that when a software upgrade is performed, all the software should be updated

The steering wheel module (SWM) stops working, this affects the turn signals, horn, cruise control, and audio buttons on the steering wheel.

There have been reports of a failed ABS Control Module causing the ABS and Check Engine warning lights to illuminate. Repair or replacement of the failed module will be required to correct this issue.

During the diagnosis of the symptoms the technician may pull diagnostic codes from the Engine Control Module that point to a lean air/fuel mixture. If no vacuum leaks are found, then the mass air flow sensor (MAF) is often the cause.

Replacement of the MAF will be needed, along with a reset of the Engine Control Module and erasing of the diagnostic trouble codes.

It is not uncommon for the exterior light bulbs to burn out prematurely. No repair option has been reported other than replacing the failed bulb.

Front and/or rear sway bar end links may wear out prematurely, causing a knocking noise from the front or rear of the vehicle when driving on bumpy roads. Our technicians recommend inspecting the links at each service, they should be replaced if any looseness is found.

Problems have been reported with the automatic transmission. Our technicians recommend complete diagnoses before beginning any repairs.
