Failure Date: 05/13/2018

While driving at highway speeds, passenger door suddenly comes unlatched. Doors are automatically locked when driving. The information system reports a door open, the interior lights flicker on and off with the door vibrating by the wind at 70 mph. Also, the window starts going up and down about a half inch like it would normally function when the door is opened for clearance. This has happened on a road trip, and was in a place where it was difficult to find a safe place to exit the highway, the door, after closing, appears to shut properly, and the lock seems to function. Then, when there is a bump or dip in the road, the door becomes unlatched again. This is very scary to have the door come unlatched for no reason at all. There was not a passenger on this trip, so it was not accidentally opened. There was a small dog with me, and she was terrified by the noise, and the window movement. I was terrified that my dog would go out the open door. There are other complaints of this happening to other owners, so it is not a rare occurrence. Volvo should issue a recall to repair the doors to prevent them from opening unexpectedly. Reference NHTSA id numbers 10680779 and 10616590.

While driving either the passenger door or the driver door suddenly becomes unlatched even when locked and the information message system comes on saying passenger (or driver) door is open and cabin lights come on. I am required to pull over and resecure doors. This issue has escalated to a nearly daily occurance. This problem should be fixed by a recall as doors are not supposed to automatically come open on a 7 year old car that has never been in an accident. I have made an appt with the herb gordon Volvo dealer in silver spring MD for an assessment.

My brakes were making a weird squeaking noise in front. I took to orange county Volvo dealer twice, both times was told nothing was wrong. Two weeks later, I experienced complete brake failure,without warning and the only way to stop was to hit the car in front of me. No warning lights illuminated, there were no other warnings prior to complete brake failure. I called my dealer who denied any problems. I had it towed to another dealer (power Volvo)who identified the problem as a complete brake booster failure. My dealer said there was no way the noise I previously complained about (weird squeak)could have been due to a brake booster problem(he said booster failure makes a hissing sound). Volvo of north America (vona) "inspected" the vehicle and stated that the problem is "intermittent" and that when they drove it, they could not find a problem, but that due to the fact that power Volvo experienced a problem with the booster, it should be replaced for safety reasons. In a voice message to me, vona stated that the problem was a "safety hazard" but since my car was "so far out of warranty," vona would not pay for the cost of the booster replacement (nearly $3,000). They denied that it was their responsibility to fix the damage to my car, and denied that the dealer improperly diagnosed problem. Prior to inspection, vona said they would pay for the fix if the booster "failed to perform as designed. " now they say that the booster was not designed to provide any indication that it was going to fail prior to causing a complete brake failure. So, basically, vona says it is proper for these boosters to fail, and it is proper for them to fail suddenly, without warning, causing a complete loss of brakes. And that this is normal. Later versions of Volvos have brake failure lights. My make and model does not. I could have died and/or killed someone, and Volvo does not care. Luckily I was traveling slowly coasting toward a stop sign when this happened.

I own a 2000 Volvo C70. The car was operating normally driving 65 mph and while driving went into what is called 'limp mode' causing a near crash. This happened a 2nd time later that day. The car now surges at various speed and is unsafe to drive. The car is at a Volvo dealership right now. The dealer indicated that they are aware of this saftey issue (etm failure widespread in these cars) but Volvo is being difficult in authorizing replacement of these etm units despite a 10/year 200,000 extended warranty.

Driving home from northern wisconsin at 60 mph with the cruise control on. Suddenly the ets (electronic throttle system) light of my 2000 Volvo C70 went on, the cruise control went off and the car would intermittently lose power. I managed to get home and have a local mechanic look at it. He could not find anything and only replaced the gas filter. The following (last) weekend, making the same trip, the ets light went on and stayed on most of the trip. The cruise control would not work and the car performance declined dramatically. The day after I got home (mon, aug1) I took it to a Volvo dealer who charged me $975 (!!) for a new ets. The car has only 55,000 miles on it.

On 4 separate occasions (3 city driving <35 mvph, and 1 hwy driving 60 mph) my 2001 Volvo C70 convertible suddenly lost speed to <5 mph. On 3 occasions, I was able to restart the car, although after several attempts, and still get to my destination and back home without problems. During the highway travel, which was on a very rainy evening, I was able to keep the car running , after difficulty restarting, at slow speed. And with a lot of prayers, finally got to a parking lot where I left the car overnight, called for a ride home, and another ride to pick it up the following morning. Took it to honolulu Volvo dealer who said it was the throttle, module and computer, and cost over $1000 for parts alone. I did not have it replaced (they were special order from the mainland), and they said the car was drivable. I now have a temporary replacement which I need for work while the Volvo is parked in the driveway!.

(1) engine degraded performance. . . Felt like engine was 'missing' and rpm's surged. (2) engine completely stopped in heavy morning rush hour traffic. (3) electronic throttle sensor failed and was replaced by stillman Volvo. Old part unavailable by us. Perhaps Volvo may have it. Incident date is a rough estimate as I do not have the receipt here at work.

My wife and I leased this car in April 2004 . Since that time we have had it to dealer for service eight times for starting problems. The car can be hot or cold. It will not stall while running this is just when you go to start it. So far, they have replaceed an immobilizer two times,an engine speed sensor three times, replaced an engine immobilzer antenna ring two times, a main relay once,totally reloaded the computer system once,and replaced an rpm sensor once. This is by far the worse car I've ever had. I still have one year to go on the lease and we don't even feel like driving it. I defiantly want to pursue the florida lemon law on this car I want Volvo to take this inferior product back now. My wife is a Ford retiree and we leased this car mainly because Ford owns Volvo. What a mistake.

I bought my 1998 Volvo C70 convertible in Jan 1999. On may 20, 1999 at approx 11:45 pm, I was driving in the left-hand lane on rt. 175-w in columbia, MD, approx. 1 mile from my home. Stopped at red traffic light at dobbin rd/rt. 175 intersection. No other cars. Light turned green. Proceeded forward. I was accelerating forward then rpms dropped. I pressed on the pedal and had no response. The headlights faded out and the rpms dropped to 5 mph. No cars around me, I stopped the car, put into park and tried to restart it twice. Nothing happened ãƒâ¢ã‚?ã‚? no sounds from the engine. I immediately put my hazard lights on. Then a car passed me on the right. I saw headlights of a car approx. 200 feet behind me in the same lane. I said out loud, "please don't hit me. Get in the other lane. Please don't hit me. " that is the last thing I remember until waking up in shock trauma emergency room at u of MD medical center in baltimore, MD lying on a gurney - 2 policemen at my feet and my parents on my left. Somewhat aware that I had a neck brace on, but more concerned at the time that my head was killing me. I had a large gash in the back of my head that required 8 staples. I fractured 2 vertebrae in my neck, (c4, c5). The doctors decided on natural healing instead of surgery. I was required to wear a sumi neck brace for 12 weeks. I was admitted to the orthopedic critical care floor for 6 days. I received morphine and percocet. After 6 days, I was released to my parents care to cont. Round the clock care giving. I was unable to take care of myself - required assistance to take a bath and supervised when using the toilet, eating, and sleeping. My mother drove me to my doctor during the 12 wk. Period. The sumi neck brace was removed on August 12, 1999. After which I wore the cushion whiplash brace for another 4-week period. Did not return to work until mid-sept 1999.
