Engine stutter / stall / engine speed reduced and not drivable - multiple occurrences before and after repairs over period of 5 years. Dealer repair 9/27/00 13941 miles replaced throttle body. Second instance records not readily available - believe replaced manifold. Third instance 9/16/03 36061 miles - replaced multiple components until problem went away. Fourth instance July 2005 approx 75000 miles tracs, ABS, check engine light with erratic vehicle speed - had to keep throttle high RPM but diagnosis was wheel speed sensor repaired and problem went away - but starting to show same stutter on start up that predated first failure - has not failed yet, but wife refuses to drive as unsafe due to multiple failures and loss of power / speed in traffic. I believe this car is an example of the investigation in work - ref PE05041.

My name is [xxx] and I currently own a 1999 Volvo V70. On August 1, I heard on the news that NHTSA was investigating a potential engine problem with Volvo. This was the same day I was taking my car to a local Volvo dealer for its 150,000 miles service and one of the problems I was planning to report was that the car stalls occasionally when I am driving or just looses speed. I have reported this problem in the past two years to at least three Volvo dealers in the New York/New Jersey metropolitan area and I have been told in all occasions that the problem could not be replicated when conducting the service. The stalling problem began in 2003 and has happened 12 times to date. In one occasion I was driving at 50 miles an hour in a highway when this happen. My wife and my child were in the car then. We were all unharmed. When I took my car to the Volvo dealer on August 1, I got a call for the service person and I was told that the throttle of the car had an internal fault and needed to be replaced for almost $1,000. I was also told that this was the reason why my car was stalling or loosing speed. However, knowing that the car model is currently under investigation for a similar problem, I decided not to fix it until the outcome of the investigation is known. In my opinion, this problem exists with the Volvo models -- including mine - and encourage the NHTSA to pursue the investigation. Thank you.

Malfunctioning of the electronic throttle system (ets) on my 1999 Volvo V70 station wagon caused me to lose power or stall completely while driving. It happened several times prior to having the ets replaced. It occurred for me at low speeds and in light traffic allowing me to get off the road. I was able to restart the engine after a short time interval. It could have been a major safety hazard if I had this failure at highway speeds and in traffic. This occurred several months ago and has been repaired at my expense, but on reading an associated press article today on an investigation of this problem by the NHTSA, I am submitting this as another instance of the problem being investigated. The air conditioning compressor and power windows had to be replaced. Currently, the check engine light is on.

We have a 1999 V70 Volvo station wagon that about 1 year ago began losing power and/or stalling without warning while I was driving on the highway. It would re-start if I was able to gun it and get the car moving. Volvo replaced the throttle system and the issue seemed to be resolved. In May 2005, the engine again began to lose power as I decelerated while driving on the highway (e.g. when approaching a toll or in traffic) and then would completely stall once I exited the highway onto the local roads and was driving at a slower speed. It appeared to happen more frequently when I had a full tank of gas and/or the air conditioner was on. It would re-start fairly easily. The Volvo dealer where we purchased the car (summit, NJ) looked at the car in may and could find nothing wrong, as the computer did not register any failure; they returned the car to us as is. It continued to happen periodically and eventually would not re-start. On Monday, June 13 I had it towed to a local repair shop in jersey city who could find nothing wrong; they returned the car to us as is. On Friday, June 17, we then brought it to another Volvo dealer (montclair, NJ) where three mechanics looked at it over the course of one week and could find nothing wrong, again citing that the computer did not register any failures. It has happened a few more times, so now it is at another local repair shop (garwood, NJ) where the mechanic can find nothing wrong. I have not driven the car since mid-June as I have two small children and do not feel safe driving a car that can stall without warning in highway traffic and be slammed from behind.

When the brake pedal was depressed, the brakes didn't engage and the vehicle failed to stop, as a result the driver had to continuously pump the pedal to stop vehicle. Consumer stated there was complete and total brake failure. The consumer had the ABS unit that was replaced. The check engine light illuminated. The dealer reset the light.
