RepairPal has identified the most common car problems based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.
The engine may develop an oil leak from the lower crankcase portion of the engine block. Our technicians tell us that the engine must be removed from the vehicle to properly repair this oil leak.
The fuel pump may fail causing the engine to stall and not restart.
Door lock mechanisms not operating properly. Doors may not lock/unlock.
Replacement of faulty door lock actuator required for proper operation.
The service 4WD system light may illuminate with no fault codes stored in the final drive control module (FDCM). Our technicians tell us a software update for the FDCM is available to correct this concern.
The sky slider sunroof may not open. A software upgrade for the control module is available which should correct this concern.
A no crank or no start condition may develop due to electronic lockup of the wireless control module (WCM), also referred to as the Sentry Key Remote Entry Module (SKREEM). When this module fails the remote keyless entry system will also not operate. The WCM is commonly replaced to correct this concern.
A Check Engine Light may illuminate indicating a "Cylinder #3 Misfire." This normally occurs in hot weather after the vehicle has been driven, parked for ten to twenty minutes, and then restarted. Heat from the exhaust vaporizes fuel inside the #3 fuel injector and causes the misfire. Installing an insulator sleeve normally lowers the temperature enough so the fuel will not vaporize.
Water can leak near the A-pillar, at the front edge of the driver and passenger side doors. An improved seal is available.
On vehicles equipped with V6 engines, the Check Engine Light may illuminate and code P0339 is stored for intermittent loss of the crankshaft position sensor signal. Our technicians tell us that adding a shim to the crankshaft sensor will commonly correct this issue but in some cases the flex plate may require replacement.
A knocking sound my be heard from the engine at times with the air conditioning on. The cause could be the AC compressor itself, if that is the case there is an updated AC compressor to correct this issue.
If the engine does not crank (or cranks but won't start), the wireless control module (WCM) may have locked up. This is due to static discharge through the ignition key. A revised model should be installed, but simply disconnecting the negative terminal of the battery for thirty seconds will temporarily reset the module so you can start the car.
Replacing a pressure solenoid valve in the transmission valve body may fix an issue where the transmission "hunts" between first and second gears. Our technicians report that customers sometimes describe this complaint as surging or bucking.
The battery B+ cable has problems with the terminal end necessitating replacement. Symptoms may include no start, cranks wont start, warning lights coming on and other odd electrical issues. The B+ cable end is located in the engine compartment fuse box near the drivers side shock tower.
Several issues occur with the door locks on the Volvo C70 and most are because of the door lock assembly. What happens is that one door will not lock while the other one does. In other cases you will lock the doors and then one of the doors will immediately unlock.
The problem is that the door lock assembly is defective and will need replacement. Replacement of this assembly on the C70 is very difficult and is not recommended by a novice. Getting the door and window aligned properly so that you don't get air or water leaks is very, very difficult.
The steering wheel module (SWM) stops working, this affects the turn signals, horn, cruise control, and audio buttons on the steering wheel.
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
Shifting harshness and shuddering issues related to the operation of the automatic transmission have been addressed by factory service bulletins. The shuddering can feel like the vehicle is being driven over rumble strips.
Rear differential and axle seals are prone to repeated leaks.
If the automatic transmission does not shift properly and the Check Engine Light illuminates, the speed sensors in the transmission may have failed. The sensors are simple and inexpensive to replace.
