2000 Volvo S80: adaptive cruise control problems

Filed Sep 19, 2009 · Transmission · 86,000 miles · CA

Own a 2000 volvo s80, I began to experience an uneven idling when driving either low or high speed, whether on cruise control or not. The car idle goes out of control, it feels as if the car goes on limp mode, I'm then compelled to accelerate to compensate and regain speed. I had the car checked, had the vehicle speed sensor replaced, complete tune up, but the problem remains. I did my research on the web only to find out that this problem is part of a recall from volvo. I took the car to a volvo dealer (volvo of los angeles) with the recall documentation, they kept the car for a week, then I was told that volvo does not repair the problem unless the computer code show up in their system, even though the symptoms of the car are clearly depicted in the federal safety agency action #ea05021. Driving this car is unnerving, as I do not know whether it would respond in time, when I have to gain speed on the freeway. The car failure is occurring more often, getting worse as I drive, sometimes I do not know if the car will respond as step on the gas to proceed after a red traffic light turns green. I'm disappointed with my volvo dealer for not addressing the issue.

1. Following download of recall software performance has been vastly reduced and now only achieves 8.2 mpg. 2. The ABS control module functions intermittently and usually in the failure mode. Abs brakes do not function properly-replacement $950 3. While backing (cold engine), brakes fail to stop the car for several seconds (feet). 4. The vehicle stalls mostly on turns but on straight away. A. Car now shuts off approx 6-8 times while driving, dangerous while driving at interstate/highway speeds. It "surges" forward and the lights (dash and headlights) fade - vehicle stalls with no power steering or power brakes. 5. Cruise control fails ?? Up hills/down hills shuts down. Now is inoperable. 6. The electronic door locks malfunction intermittently. 7. Following error codes display and total mileage, trip 1 & 2 mileage displays default to ?? --------?? And mileage does not log on the odometer: a.brake failure stop asap b.coolant level low stop asap c.ABS failure / service required d.stc service required e.power steering failure - service required f.emission system service required g.stop safely and restart engine h.alarm system service required I.alarm triggered j.emission system service required k.no oil pressure stop asap l.check engine. *nm the ball joint, driver side window motor, sunroof switch were replaced. Numerous bulb replacements and replacement of mass flow sensor. The cooling fan malfunctioned. The ABS control module would function intermittently which would cause the ABS to not function. The power steering failed. The vehicle will completely shut off while driving. The cruise control was inconsistent, the vehicle would loose power with the cruise activated.

Subsequent continued driving results in the second code pending or permanent. The remaining codes will be added in pairs. First dealer reports I have 18 codes but factory vadis indicates can only store 15 codes maximum. Requested additional $300 to adjust fuel trims, check exhaust and intake leaks, check o2 sensors, work declined. Second dealer reports needs complete transmission. No attempt to solve complaints by dealer, contacted volvo customer service and they declined to discuss problems, they declined any further involvement. Car had salvage title 2+ years ago from minor accident which prematurely deployed air bags, repaired and returned to service. I am retired ase master mechanic, service manager, and sae member, this is not a transmission issue but caused by the erratic actions of the throttle body system and module. Transmission passes all conventional tests. Results stuck in gear can be corrected by cycling the ignition switch off and back on. This can be done by pulling to the side of the road and stopping to cycle the key or traffic permitting placing in neutral and restarting and then back to drive. No observed failures above 65 MPH. Tsb send wrong signals to "network" are translated as instructions resulting in poor fuel consumption, high emissions, abnormal wear and tear on transmission, ignition switch, starter, and related components for normal operation, plus a dangerous driving condition.

My 2000 volvo s80 2.9 vehicle started surging then hesitating, back & forth, at all speeds up to 70 MPH interstate speeds while cruise control was on and off. When cruise control is on, after about 5-10 miles, cruise control turns itself off & car suddenly starts decelerating. After about 1 week of this, on 6/30/06 performance reduced message appeared. On 6-24-06 engine service required message appeared for a short time. After stopping and turning motor off for about 30 minutes to read owner's manual, started motor again & message has not reappeared. When cruise turns itself off, you cannot turn cruise back on until motor is stopped & restarted, then you can turn cruise control back on for about 5-10 miles then it will go back off. Surging and hesitation continues with steady pressure on accelerator (trying to maintain constant speed) and cruise control off.

I own a my 2000 volvo s80 2.9. Upon driving in town the car suddenly lost acceleration and engine started shaking. The message reader prompted me to stop and restart the engine. Well I did, in the turning lane, but it did not help. I pulled out of the cross section "shaking". My mechanic says the onboard computer prompts him to a faulty engine throttle module. Well this car has only 48000 miles on it. On the same note: on my 1999 s70 glt at around 60000 miles the same part had to be replaced, because it shut down the cruise control time-to-time.

2000 volvo s80 -- defective throttle control module subject of preliminary evaluation pe05041 on april 20, 2005, while driving using cruise control at highway speeds the car would lose and regain power frequently. On april 21, 2005 while driving at approximately 35 miles per hour on a two lane road without a shoulder the car lost significant power and a variety of warning lights came on with instructions to turn off the engine. Was able to restart the car with limited power and took it to the dealer. The problem was diagnosed as a faulty throttle module and replaced at a cost, paid 100% by me, of $919.16. Subsequently, the cruise control occassionaly exhibits the same slight loss and resumption of power. While I was lucky in that I was able to turn into a driveway when nearly all power was lost, had there been traffic on the two lane road I was subject to being rearended. The frequency of this failure, which I understand to be the subject of a class action lawsuit in california contending there is a "hidden warranty" practice being conducted by volvo which at times pays for the expense and other times not, is worthy of your official evaluation. Thank you.

The vehicle would have small changes in speed over the course of several months the car began to lose power and then stall at speed between 50-75 MPH. The car restarted but speed was inconsistent even with cruise control. Dealer was contacted and they advised that is was probably the electronic throttle control module, this was without further inspection of the vehicle. The service work was done and so far the problem has been corrected.

At 70mph my car said reduced performance, and within 30 sec. My cruise control failed, the car reduced to 5mph, and there was no acceleration. I was in 5 lanes of rush hour traffic doing 70-80mph. An eighteen wheeler skidded approx. 50 feet in order to avoid hitting me. He then had to block off two lanes of traffic to assist me to the shoulder. My car would only coast. It was a near death experience for me. I'm thankful my children were not with me. After being turned off over night, my husband attempted to drive it to the volvo dealership. He experienced the same. We were told that it was due to a computer chip malfunction. A chip which controls the throttle, fuel-injection, and cruise control. Wow! The service rep. "we haven't seen anymore problems after replacing the chip". We asked why has this not been recalled. The rep. Said "there have to be so many accidents and fatalities reported, before they will recall it". This has left me very disturbed, and reluctant to ever drive a volvo again. I feel sure if it hadn't been for my quick use of the hazard lights, it could have been fatal. The truck driver also concurred. I do not want this to happen to anyone else. They may not be so lucky.

Similar to a the federal safety agency complaint number 873996, this vehicle (2000 volvo s-80 t6) shut down during highway driving at 70 MPH. Console message status indicated "engine system service urgent" after coasting to safe location, engine would not re-start until cooled. After starting, the message status remained the same, but cruise control was inoperable, automatic transmission would not operate above 2000 RPM in both automatic -or- manual mode. Early symptoms of this problem may have been falsely manifested as poor automatic transmission shifting performance in 3rd, 4th, and overdrive gears. The symptoms have persisted until failure since the vehicle was purchased. As of 10/4/03, dealer had replaced the entire electronic throttle body (carburetor) at consumer cost of $926.70 and recommended cruise control module replacement estimated at $860.00 original vehicle history including complete transmission replacement at 9000 miles is available from owner or dealer.
