Most reported Volvo problems

 

Verified for the Volvo V70

The anti-lock brake system (ABS) Control Unit has a high failure rate. When this fault occurs, the ABS light will illuminate and codes may be stored indicating a problem with the ABS Pump Motor, or Wheel Speed Sensors, but the problem is the ABS Control Module.

Other symptoms may include an illuminated Check Engine and transmission shift light, and the speedometer may stop working as well.

Note: The brake system will operate normally however during a panic stop the Anti Lock Brakes will not work and the wheels may lock-up, causing a lack of vehicle control under these situations.

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

Verified for the Volvo XC90

Many complaints have been reported regarding Volvo XC90 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

If the check engine light is on and diagnostic trouble codes point to the air pump system, then the entire system needs to be checked.

There are a few issues that arise from the vacuum lines becoming plugged or disconnected but the most common issue is the air pump itself fails. The reason the air pump often fails is from a defective air pump check valve that allows exhaust gasses to contaminate the pump.Replacement of the air pump and check valve is necessary to address this issue.

One thing to be aware of: If the problem is not addressed eventually these exhaust gasses can contaminate the MAF Sensor and Oxygen Sensors as well, causing the engine to run very poorly and cost much more to fix.

The evaporative emissions system has problems with the purge valve, tank pressure sensor, and the fuel cap. All of these failed components will cause the check engine light to illuminate. To prevent turning on the check engine light accidentally, make sure the fuel cap is installed correctly after re-fueling

Mass airflow sensor (MAF) failures have been reported, causing engine idle problems, as well as acceleration hesitations. The Check Engine Light will normally illuminate when the MAF starts to fail.

There is a computer that controls all these items and it's called the rear electrical module, or the "REM". To temporarily address this issue you can pull the fuse from the rear fuse box labeled "REM" and everything should start working again. 

Volvo has updated software for the REM that will help prevent this from happening again. See a Volvo shop or Dealer and have this and all the software in the vehicle checked and updated every 30,000 miles.

Verified for the Volvo 850

If you hear a loud knocking noise from the rear of the car while driving then there's a good chance the rear upper shock mounting plate is broken. We suggest replacing both rear upper shock plates at the same time because the other one is likely ready to fail as well.

The electronic portion of the ignition switch may malfunction, causing some dash lights to stay on. When this happens, a wiggle of the ignition key should temporarily return everything to normal.
