Vehicle Speed Control Problems of Subaru Ascent

The vehicle was being driven on a public road, going roughly 45mph. I felt a very harsh studder/clunk and completely lost responsiveness from the accelerator. There was no throttle response even pumping the pedal all the way to the floor. I was able to coast to a parking area and make a safe stop. Once I was stopped, I turned the car off, back on again, and it got me the rest of the way home. This was the most severe instance of the problem, but both primary drivers of the car have experienced the accelerator going unresponsive at different times. Since this was a severe safety related concern, we took the car in for service at the dealer, but were told they were unable to reproduce the problem and did not make any repairs. We provided the dealer with a video we captured toward the end of the latest incident, but they haven't been able to find any cause. There were multiple warning lights on the dash, but no codes were stored. We did have another warning light for a brake system error, but there was no code stored and the dealer was unable to located the source of a voltage anomaly in the parking brake system. We've taken it in to another dealer service center for additional diagnostics but the original shop is refusing to provide the complete details of any diagnostics and corrections they have made, so we don't have the original data that was pulled from the car.

The driver was driving into a parking lot preparing to park, when the vehicle accelerated and started going forward at a higher speed. The vehicle struck a parked vehicle, then travelled across the parking lot, over curbs, a grass median, landscaping, and struck a rock building at a high rate of speed, causing a partial collapse of the wall. The vehicle is available for inspection through the insurance company. No analysis of data was done and nothing was inspected. There were no symptoms of the problem beforehand. The vehicle has automatic emergency braking, but it evidently didn't operate. It is unknown if this was caused by driver error in accelerating and never braking.

Unknown defects in some vehicles that could cause sudden and unintended acceleration without driver input yes, our safety was at risk. The vehicle was clearly not in our control. A police report was generated. The car plowed through the garage no control to brake the damages are being inspected by insurance. There were no waring lights that I could see.

There was a sudden and unintended acceleration without the driver input while braking to park going approximately 1 - 2 mph. Our safety was at risk. The vehicle was not in our control. A police report was generated. Rather than stopping we crashed into the apartment building causing significant damage to both the apartment and our vehicle. There were no warnings, no automatic braking to avoid the collision, the air bags did not deploy. The total damages are still being determined by the dealer and insurance company.

The vehicle hesitates like it doesn’t want to get up to speed, despite pressing the gas pedal to accelerate. The rpm needle bounces. Dealership has not been able to “replicate the hesitation I feel when accelerating. ” they originally tried to say I didn’t tell them the problem was happening when it had time to warm up, which is a lie, I have all the scheduling notes made by the employee who set the appointment up. Dealership said it passes diagnostic testing despite my serious concerns as the owner driving it daily. No lights are lit up on the dashboard which is another reason why the dealership is saying everything is fine. It’s already had a firmware update in July and the dealership is very dismissive of my concerns. I made multiple calls before appointment telling them it’s happening more frequently around 20-30 minutes of drive time and to make sure I have them the full picture well enough in advance for them to make adequate time to look at my vehicle.

Adaptive cruise control, automatic emergency braking, forward collision warning, lane departure warning, lane keeping assistance, eye sight, rab, some ! symbol, and check engine light are all on and not working. You know everything that makes a Subaru. This is not the first or even second time. We are on the fourth instance of this happening. We live 2+ hrs away from the closest dealers. The first few times it occurred, we called to make a appointment. Each time was always a few weeks out and the issue would clear a day or two before. This last time has been going on for 6 weeks. We both work full time and have a very sick kid so making a appointment is hard. This last time I asked if I can drop in just for a scan due to being in town for an appointment. Was met with we are backed up with way to many repairs. Also it would not be fair to any other people. It is most likely your gas cap. I have made sure the cap is tight as it can get every time from the first time it occurred. So all safety features on the Subaru Ascent just stop working if the cap is not tight. Not only is this a major safety issue their qa is asleep at the wheel. Known issue, just check the forums.

My wife was pulling into a parking spot at a safeway in seattle. The car, instead of stopping, sped up when she stepped on the brakes, slamming into a brick wall. She shifted into reverse, and the car sped backwards, then shifted to drive, and sped forward and slammed into a wall again. She shifted to park and pulled on the parking brake. Then, after 5 minutes with the car off, she drove home without incident and parked, although the car was severely damaged.

Vehicle started off with the radio not saving channels. It would reset the radio every few days. A message would come on the dashboard which would say the car will be restarted in a few hours. And a light not working. Took in and they said it was battery. Replaced. Then got back. Within week or so. Car had all lights coming on and off on dashboard. Started jumping. Even drove backwards when put in drive. Took in and they replaced transmission. Within the week after getting back, the car was skipping gears. Another transmission. Then back in for radio not shutting off when car off and locked. Would run for hours. Also the trunk door would not lock. Took and they said it was a switch. Radio again still resetting. Radio will randomly shut off and then turn back on. The rear trunk will lock and then not unlock. Car is still driving rough. Clearly the car has electrical issues. It is back in now.

When trying to accelerate around a truck on a highway, the car refused, felt like it was going to stall and every light on the dashboard lit up. My speed was probably around 60mph, when I tried to quickly get around this truck. It was full of furniture that I felt was loaded in an unsafe manner. This is the second time the car has done this and the cvt chain slip was supposedly fixed in a recall n December. This time Subaru said it was a leaky gasket in the inter cooler??.

When holding speed constant between approximately 20-35 mph, or under very light acceleration in this range, vehicle seems to jerk, surge, pulse, or similar. It feels similar to being in the car with someone learning to drive a manual transmission.

I have had my lane assist come on by its self a few times, which is very dangerous because it seems to take over and will pull on the steering wheel. I’ve also brought my car back to the dealership a handful of times to have it hooked up to a computer and also someone ride with me because the car will either hesitate to accelerate or stutters and doesn’t seem to want to go when I am between 20-30 miles an hour. Other times when I’m at a light or stop sign it hesitates also. I was told there was nothing wrong with it and they reprogrammed to transmission but it didn’t help at all.
