1999 Volvo S70 Problems
RepairPal has identified the most common problems with the 1999 Volvo S70 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
An abnormal vibration maybe noted due to a worn upper and/or right front engine mount. Replacing all worn mounts may be necessary to correct this concern.
Front upper strut mounts may wear prematurely, resulting in loud noise from the front of the vehicle when going over bumps.
A broken vacuum hose near the power steering pump deteriorates and can cause a rough idle and the Check Engine Light to illuminate
One or more door lock assembly may fail and cause door locking/unlocking problems.
The master window switch may fail, allowing the windows to move in one direction and not the other.
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
Many complaints have been reported regarding Volvo S70 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 fix this issue so if available, the software should be updated before any repairs are made.
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
One or both of the front wheel bearings may fail resulting in a rumbling noise from the front wheel area when driving over 25 mph.
The AC evaporator is prone to leaking, causing the air conditioning system to lose refrigerant and stop blowing cold air.
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.
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.
*make sure to always properly secure the fuel filler cap after fill-up!
When braking at highway speeds or when descending hills, a rumbling or vibration felt throughout the vehicle can be from the rear brake rotors. Replacement of the rear pads and rotors is the fix, and make sure that the shop installs the special cut-out shims available from Volvo to help prevent this in the future.
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.
