2019 Subaru Ascent: multiple warning lights

Filed Aug 18, 2024 · Transmission · MA

While driving on a road with a lot of hills our car sudden lost all engine power but all of the lights and engine were still on. We pulled over but kept the car on and it seem to resume power. Then about 1/8 of a mile later it happened again. We shut the car off completely for 5 minutes and turned it back on and we were able to drive it normally for another mile. It then happened three more times on our way to a safe spot to pull over. The fifth time it happened all warning lights on the dashboard turned on (see picture). The speed in which it happened varied. It is important to note that we brought it in for service on 8/8 for a standard interval service at a Subaru dealership and have brought our car in multiple times to address issues with the transmission.

All warning lights came on last week may 5th 2021 while I was drivingthecarhone after dropping my daughtertoschool. I pulled over and called the dealership and was advise to take the car in. As I drove the engine started to lag and icouldnotdrive more than 45miles. Took the car to the dealership and found out the transmission was bad. This car is 2 1/2 years old and I've had so many problems with it. When the CVT was replaced the car never run the same, I've taken it to the dealership several times and let them know that there is something wrong with the car. It lags and hesitate duribg acceleration. Unfortunately they could not replicate the issue and that it was normal. Then this happen. I have reported the issue to subaru of america.

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.

The battery has repeatedly been drained to the point where the car will not start. The cause appears to be leaving the tailgate open with the engine off for an extended period of time, even if I turn off the small cargo light and some light ti avoid battery drain while the tailgate is open. This has happened at least 4 times and required me to jump start the car. The dealership replaced the battery after one of these incidents and told me the battery had been severely depleted, necessitating replacement. The most recent time this happened, after I jump started the car the check engine light stayed on as did all warning lights for the eyesight safety systems the x mode traction control system, and the eyesight system did not function. It has been fortunate that every time this has happened I've been at home where I could jump start the car. If this happens on a trip we would be stranded.

Lift gate not working. Getting stuck close and draining the battery. At only 17000 miles we have had to replace the battery twice. When trying to start the car will make a vibration sound and all lights will come on but the lift gate is suspended close and the vehicle won't start. This has happened overnight. And when the battery is jumped and the vehicle will start, the lift gate will still not open.

Check engine light - diagnosis ' vehicle loses power after rapid acceleration above 45mph. A whooshing sound occurs and then acceleration is limited. All warning lights flash including 'check engine.' this has occurred once about a month ago and diagnosed as a poorly replaced gas cap'although it was actually on securely. It occurred 2 weeks later 3 more times within two days. I brought it in with the lights on and issue still occurring to subaru pacific. They cleared codes and tried to recreate issue without success. They released the car back to me after corporate deferred to them. Upon driving out of dealership, the same thing happened only after acceleration above 18 MPH'all warning lights back on and sputtering/jerking/loss of power. Whooshing sound. Dealer is in possession of the car again to look into it. Also, there tends to be a grey-blue hue to the exhaust each time car starts.

Driving normal, 30 MPH on a flat road, when all dash lights lit up. Rab, break, check engine, every single dash light at the same time. We then lost power steering, and when we pulled over couldn't get the car into park. Eventually after fighting with it, car went into park. Attempted to restart it, and it did re-start but with the same lights on the dash. It was unable to be driven and had lost power in a potentially dangerous situation. Car was towed. Dealer has had it since then, now 01/21/20 and they know it's electrical, it has happened again while they drove it, but they cannot figure out what the problem is.

When trunk or doors are open more than an hour battery will drain to the point where the engine is unable to start. This has happened twice with my vehicle and I have heard reports from other ascent owners experiencing the same issue. From what I can tell the issue is caused by the door sensors remaining on as long as the door is open even if the engine and accessories are turned off. Vehicle was stationary both times it happened, parked in garage. All lights and other electronics were turned off, only door was left open.

A couple of months ago, my wife started the car and backed off a parking lot. When she pressed the brake and felt wired - the brake could not be pressed down and felt like it's jammed somehow. The car did not stop even she switched the car to parking! It eventually stopped after hit a parked car behind. Because the speed was very low so there was no obvious damage to both cars. But after restarted the car, all the warning lights went on - rab, eye sight, at oil temp, low tire pressure, and the sun roof and sun shade not working.

The battery keeps dying when I have the tailgate (tg) opened for extended periods of time such as when dog training. The first time my battery died, I was the last person on the training grounds. I closed the tg and lights were flashing and beeping for a few minutes. The battery died and the tg was shut and wouldn't open. I panicked b/c I could not get my dogs out and I was alone in a vast wooded area. This is a terrible safety issue b/c if I did not have cell phone coverage that day, my dogs would've been trapped in the car without water and I would have had to walk a very long way to get help since the subaru roadside assistance will not work without cell coverage. In feb., I was dog training in areas of georgia where there is no cell phone coverage. Three days in a row, my battery died. Fortunately, another member of our group jump started the car. The local dealer in tallahassee was shocked to hear that leaving the tailgate open would drain the battery. Subaru says this is how the car was designed. In addition to installing a new battery, they installed a battery disconnect switch, which I purchased to prevent my battery from dying. Every time you flip the switch to cut the battery off, all the presets go back to default and have to be reset. And now randomly all the warning lights now come on and the eyesight system fails b/c supposedly the system is sensing a drop in voltage when the battery disconnect switch is being used. It seems to me that subaru didn't think this through given that they market to the outdoorsy type of person, dog owners and campers. They need some sort of fix to correct this safety issue to allow owners to turn off the power to the tg when needed so they are not left stranded when they are 'off the grid' as their commercials tout. .
