Problems with 1999 Volvo S80 EXTERIOR LIGHTING

During normal driving conditions at night, the low beam (dipped beam) headlights failed while out of town with my wife and two daughters. i was able to drive to a safe location using the high beams. a check of headlamp bulbs and fuses showed that everything was in good working order and i was left scratching my head. the headlights are still not working three weeks later, and i finally know why. volvo owners exchange information on various websites and on more than one i found people suggesting that the cem (main computer) used "shunts" for various components on the vehicle and they were proned to shorting out due to random overheating issues. i checked the area under the driver's side dash and sure enough, there is a shunt inserted into the cem with heavy charring around the terminals. the 1999 volvo s80 was the first year of my particular model, and the first year this type of wiring architecture was used on their vehicles. the shorting of a crucial circuit such as headlamps not only poses a grave danger when driving the vehicle at night, but could also cause a fire. i feel the failure in the design of the cem and the vehicles wiring architecture could also be responsible for the random electrical problems occurring with the s80 as well. there are several websites that mention the constant "check engine" light that comes on and dealers are claiming they repair the problem after each visit, which usually end up costing over $1,000.00. there's also several examples of customers , including myself, who lose the a/c compressor randomly, and the alternator indicating that it isn't charging correctly. finally, there is also something inherently wrong with the design of the front suspension of the s80. i've paid for struts and ball joint repairs and have had them repaired through a manufacturer recall. again, the dealer claims to have repaired the problem after each visit, yet the problem has recently come up again in my vehicle. please contact me anytime. *tr

Front signal housing /lens cover keeps falling off. repaired but plastic breaks. *jb

While driving 55-60 mph, brakes were pulsating, after applying brakes again noticed brakes were fading. consumer pulled over and noticed rotors were red hot. dealer replaced front rotors and pads.*ak the gas tank had a defect that would cause a vacuum leak. the front suspension makes a cracking noise when turning due to ball joint failure. the gear shifter switch makes loud clicking noise. the rear passenger door handle could not be opened from outside. automatic transmission had slippage and shudder while up shifting, creating a vehicle loss of control. passenger side rear seat backrest cushion makes noise due to loose clips. the front passenger window developed a wind noise due to defective window seals. due to design fault, the upper torque mount bushing cracked. the driver side front headlight lens broke. the consumer is asking for a full refund of the actual price paid for the vehicle or for it to be replaced with a new equally equipped vehicle. *yh

The left rear bushings failed causing a rubbing sound when backing up. nlm
