While driving with cruise control set at 55 mph, car began to decelerate, yellow "wrench" advisory light illuminated and engine appeared to be running rough. Car slowed to a stop and I pulled the car off the roadway. I switched off the ignition and waited approximately 30 seconds. I restarted the car. The advisory light stayed off and the engine ran normally thereafter. When the incident occurred, the car was on a highway curving turn to the right. The incident occurred coming out of the curve.

The above vehicle is a 2015 Ford Mustang eco-boost convertible. It is equipped with adaptive cruise control. When a vehicle in front slows below a set speed or a vehicle cuts the car off the adaptive cruise control slows the car down, or stops it, to keep a predetermined distance. According to Ford the slowing is done by the engine and not the brakes. Once the vehicle slows, and it is safe, it begins to accelerate back to the set cruise control speed. The slowing, not being done by the braking system, does not activate the brake lights. Only when the brake pedal is stepped on will the brake lights come on which also would disengage the cruise control. We have had a couple of incidents in which the vehicle behind does not see the car slowing, by brake lights, and closes at a rapid speed on the rear of the car. Looking at a Dodge ram closing, not knowing it's going to stop, can be a bit unnerving. I have recently read that the automatic braking may be installed on future vehicles as a standard option. I can't imagine that keeping a vehicle from crashing into a forward moving vehicle is any more or less important then being struck in the rear because brake lights don't come on. I am certainly more cautious driving the adaptive cruise control on because of this safety issue. I have talked to Ford "customer relations dept" who weren't sure how to follow this up but to sent it up the ladder. I have a Ford case #cas-7876013.

The contact owns a 1999 Ford Mustang. The contact stated that while driving at approximately 70 mph with the cruise control engaged, the vehicle failed to decrease in speed when the cruise control was deactivated. The contact also stated that the brake pedal was applied, but the vehicle failed to stop. The contact shut the engine off while driving in order to stop the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and informed that the VIN was not included in NHTSA campaign number: 99v062001 (vehicle speed control). The approximate failure mileage was 165,000.

When brakes were applied to disengage cruise control, brakes acted as if they had lost power, and cruise control failed to disengage. This has subsequently occurred four more times, most recently in early October.

I was at the exit of a parking lot and waiting to turn out onto the street. When I began to turn, my car started to accelerate way faster than it should have. I hit the brakes but my car wasn't slowing down and kept accelerating. I hit the "off" on my cruise control thinking maybe it became active but nothing happened, as I began to come close to the car ahead of me I turned left onto the next street still hitting my brakes (at this point I had gone a block and a half with my brake pedal pressed in). As I turned, I had trouble controlling the vehicle I ended up hitting the curb with my front passenger side. After the impact the acceleration had stopped, I could hear something had broken, and felt it as I was slowing down because my car wasn't traveling straight and I couldn't turn easily. There were kids in the street that I didn't see before I had turned, I swerved again to avoid them (luckily just missing them because as stated before, I couldn't turn it very easily) and made it about half way down the block before my car came to a full stop (the entire time still hitting my brakes). I did not see the actual speed I was going, the car was accelerating rapidly and totally out of control. The car defect has cost me approximately $4000. 00 in car repair fees and also depreciation. It was such a hard impact that I expected my air bags to blow, but they didn't. I hope they are not defective as well.

I was leaving a stop sign and accelerated from 1st to 2nd. I was going about 30mph in second when suddenly, the vehicle went to a wot (wide open throttle) condition. The sudden acceleration caused the rear of the car to spin, striking a tree. The acceleration was sudden and completely unexpected. This is the second such occasion that this condition occurred. Cruise control was set to on as it was used before reaching the stop sign. Also, stock floor mats were in place.

Some years prior to this incident, the cruise control would cause pulling of the car. What I mean by this is that the vehicle would pull forward as if someone were towing it from the front. This would take place after the cruise control had been used minutes or hours prior to the vehicle being shut off. Once the car was turned on again, even an hour later, would cause the car to maintain its speed (usually 10 mph or 15 mph) until the brake was pressed even though the cruise control wasn't activated. This was supposedly "fixed" by Ford through a $600 "repair" of the "computer" that controls the throttle (I have documentation to support this repair). I was unaware of this site. So now I am reporting the following terrifying incident. This 2006 Ford Mustang, about 2 years prior, had its cruise control on when all of a sudden the vehicle accelerated from 40 or 50 mph to 60 to 70 mph. The brake slowed the car but the revving was out of control. Luckily I was on an open highway around 10pm but had to drive into a gas station (luckily nothing happened) and slammed on the brakes as the engine revved hitting the upper rpms. I had to shut off the car with the ignition (leaving it in the park gear and pressing the brake, mind you!) and when turned on the car again (now in park), the car again, dangerously revved. I thought the engine was going to blow out. I shut off the car again, parked still at the entrance of this gas station. I waited some minutes and turned the car on again, sweating profusely as you can imagine, and the car was completely normal. I was convinced this had to do with the cruise control. I had aaa tow the car home and the next day I took it to Ford who claimed they had never heard of such a thing. They checked the computer again and gave it an "update". I never used the cruise control again as you can imagine and no problems with the rpms or acceleration.

I purchased a 2007 Ford gt v-8 automatic Mustang on 10/10/06. One week after the purchase, I was driving, and my throttle got stuck. I pulled the e brake and threw the car into neutral. After stopped the car eventually turned, I believe because the rpm's were so high. Eleven days later on 10/29/06 I took off and the gas pedal started to take control again, yet failed to go to the extreme as the first time. On 11/07/06 approx 6:45 pm, I was driving, going about 55 mph. It was already dark outside & roads wet. After being set on a speed of 50-55 mph, I hit the gas pedal to get up to around 60 mph. Once I did, I could feel the gas pedal go down on it's own. Instinct reaction was to hit the brakes, but when I did the car started sliding due to the wet road. While the rpm's were going up, I threw the shift into neutral and pulled the e brake. Once I finally stopped, the rpm's were still extreme, and then the car finally cut off on it's own. I left the car at the dealership that evening. The following afternoon on 11/08/06, the mechanic stated that the car was ready, so I asked what they had determined. He stated that the floor mat was the issue. The first time this happened to me, I did not have the weather mat which is 5 cm thick. In addition, how can a floor mat, make a pedal accelerate on it's own? I could actually feel the gas pedal going down as if cruise control was just turned on. The dealership asked if he could drive my car home to his house to determine the issue. He also stated that he was going to put a flight detector on the car. I spoke with him on 11/09/06; he stated that the throttle got stuck on him. He stated again that it was a floor mat issue. He is going to continue to drive my car for another day or two, with out the floor mats, to see if it happens again. I find it hard to believe that a floor mat can cause such a fatal incident. Either way, I have a new car that is supposed to be my dream car and I am scared to death to drive it!.

Ltr fm (ok) wants to speak w/a Ford representative re his granddaughter 2003 Ford Mustang srs defective cruise control cause the brakes to lock up.

: the contact stated while driving 60 mph, the cruise control was activated. After the activation of the cruise control, the vehicle suddenly accelerated. The vehicle reached speeds of 80 mph and above. The contact tried depressing the brake pedal, shifting the vehicle into neutral and shutting off the engine. These attempts to deactivate the cruise control failed. The contact drove onto an on ramp to the interstate while still attempting to deactivate the cruise. The contact was able to dial 911 for assistance of the state police, who provided verbal instructions for stopping the vehicle safely. The contact placed both feet on the brakes and both hands on the emergency brake to get the engine to stall and the vehicle stopped. The vehicle was pulled safely to the side of the road where it was then towed to the dealership for inspection. The dealer stated the vehicle's cruise control would be inspected and replaced, however the vehicle was towed back to the residence where it currently resides without repair. Updated 3/29/2006 -.

January 3, 2006 the driver was traveling north on I-24 (nashville, TN. ). The cruise control was on! she prepared to turn off I-24, at haywood lane exit, she applied brakes. The car first slowed down to 40 mph. Then accelerated/sped up. The car was exited the highway at great speed. The driver braked again, the car slowed down a little. The car immediately sped up, with such force the driver was thrown to the back of her seat. Pressing the brakes now had no effect. The consumer cleared the exit lane onto haywood, the car was still speeding. The driver faced no cross traffic at the intersection of haywood lane/antioch pike ( intersection-haywood the I and antioch pike the top of the t). The driver car was stopped by running into a car and a van at a gas station. The vehicles were spun around and hit the gas station at the t. The driver has driven this highway turn off and intersection over 23 years. She has been driving this make and type of Mustang for several years. She has owned 5 Mustangs. The driver was transported to hospital by ambulance. With a broken nose, broken foot (right where the foot was positioned over the brake), cracked ribs, bruised and lacerated face/ legs. After a hospital stay and follow-up visits before being able to return to work. Ford consumer affairs was contacted and they did a telephone interview of the above factors. Questions seemed to be aimed at determining if an electronic malfunction had occurred. The questioner may have been reading from a checklist. Later, we received a letter from Ford demanding all sorts of information. This was forwarded to Ford. About 1 month later, we received a curt two line letter indicating "we are unable to offer any assistance at this time". Our insurance company elected to try to perform a crash analysis. We apprised them of the similar cruise control on this website and provided information on "rogue signals" and other data concerning this event. Results pending.

While the contact's wife was using the cruise control the accelerator would go to the floor. She had to press the accelerator repeatedly to get it to turn off. This happened twice. The vehicle has not yet been to a dealership to be inspected.

The contact states the cruise control can be set by pressing the coast button, as well as the set button. The coast button is located on the steering wheel where the contact hand rests while driving. He found this after wife was in an accident. The vehicle would not slow down with her foot off of both the brake and accelerator pedals. The contact's vehicle rear ended another vehicle, and a police report was taken. The vehicle was taken to the dealership, once he found the cruise control activated, and this was how the vehicle was manufactured. Update 1/4/2006 -.

While driving in a 55 mph zone, I attempted to set my cruise control. I did this successfully. However, about 5 minutes later, the car began to slow down as if the control was disengaged. After I realized this, I pumped the brakes to disengage the c/c. It took several attempts of pumping the brakes to release control. Once done, I was too paranoid to try using the c/c until recently. I decided to try it with no traffic around in a 35 mph zone on a straight away. The cruise control simply would not engage. I took it to an ase certified shop in ellsworth, maine to have the problem diagnosed. The shop said it was a relay that was burned out. The relay was replaced at a cost of 48 dollars for parts and labor. After replacing the relay, the c/c still does not work. I am more concerned with the sudden slow down and non-release of speed control to the driver than with getting my c/c to work again, but I would like to know what is to be done about this. Especially since it happened on a maine highway in heavy traffic. Thank you.

Vehicle's engine started racing and brakes did not respond to stop vehicle. The dealer told the consumer they could not find a problem. The consumer took the vehicle to an outside mechanic who disconnected the cruise control and the consumer has not experienced anymore problems.

The cruise control self activated which caused the vehicle to speed up and as a result the driver lost control of the vehicle. During this incident the brakes did not work. The driver was not injured. The vehicle was totaled.

Driving at 75 mph on cruise control. Needed to slow down so tapped brake pedal. Cruise would not release. Hit brake pedal again. No response. Pounded brake pedal and finally cruise cancelled. Dealership found cause to be a broken wire on the brake light switch. Luckily had room in traffic to handle the problem. Next step was to hit cruise off button.

While having cruise control on and trying to slow down cruise control would not disengage. Consumer was was travling at about 70 mph before trying to turn cruise control off. Contacted dealer, and dealer will try to fix problem.

Car is irratic and engages into cruise control and out of cruise control whenever.

While driving with cruise control engaged and coming up on traffic, consumer had to step on the brakes to get cruise control to release. Consumer felt this was unsafe.

I was driving south on I-85 with the cruise control set at 65 on a clear day. The vehicle went into a skid, and before I could stop the skid I hit the guardrail. There has been a recall on the cruise control for my vehicle (recall 99s09) which I believe contributed to this accident.

Recall 99s09 for the cruise control system not performed due to lack of parts. 99v062.

My cruise control will not turn off with the key. It retains its last known speed.
