A D V E R T I S E M E N T S

My wife and I purchased a new Subaru Ascent in February of last year. Since then intermittently there is a large blue/gray cloud of smoke that comes from the exhaust when the car is started. Have taken the car to the local dealer for repair 4 times and they replaced a part the first time but since then said that they are not able to replicate the problem. According to the assistant service manager at the dealer they have seen this problem before and Subaru America is also aware but have said "(that there is no fix for this problem)". at the second and third visits they had said "(they were going to change a part in the car but then decided not to because the representative from Subaru of America said it would not help)". the service reports for these visits only state that they are not able to replicate the problem. The dealer then said that any solutions would have to come from Subaru of America. According to Subaru of America they have not seen this problem before and they offer no remedy. From what I have learned this problem seems to be known to Subaru. I know of one person that states his "engine blew" (A2002slp@yahoo.com) after he had his car evaluated by Subaru, after many months they agreed to replace his engine. Here are some comments from others experiencing this problem https://www.ascentforums.com/threads/new-Ascent-unexpected-blue-smoke-from-exhaust-at-start-up-and-acceleration.8920/ here's a link to videos of my car: Https://www.dropbox.com/sh/ftde39F4rsz3V5E/aacljxfuchhfbrab-jksefhia"dl=0 as well as a link to a youtube thread with others stating a new engine was needed. Https://www.youtube.com/watch"V=E8cn3D4ejic I believe this problem might pose an imminent risk to any drivers of this vehicle and would welcome any help encouraging Subaru to take this matter seriously. Thanks

I have a 2019 Subaru Ascent. On July 2, my husband was driving on a rural road when out of nowhere the car started vibrating and rattling and his speed went from 60 mph down to 30 mph in a matter of seconds and the car started flashing information on the dash. And the car shut off. He got off the road and called aaa. It was an hour and a half before they got there. Nothing and nobody was around and he had to beg the tow truck driver to let him and our elderly dog ride to the nearest Subaru dealership which was about 50 miles away. I was already at the beach at emerald isle nc and had to go pick him up at parkway Subaru in jacksonville nc. This was on July 2,2020. Today, July 11, we still don't have my car back. I am thankful that parkway dealership loaned us a car to get back to raleigh where we live and bout our car, at southern states Subaru. Parkway has told us various things that could be the problem. For for several days they had to guess as the Subaru headquarters it was 'down'. as of now parkway still has my car and I have their loaner Subaru outback. This was a very dangerous situation and could have caused a crashed as well as left my 65 year old husband and dog stranded on the side of a very rural road. This is totally unacceptable and what I thought was a very reliable Subaru Ascent has greatly disappointed. Please help!!

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.

After having driven the Ascent for 30 minutes or more, turned off vehicle for about 15 minutes. After rendering the vehicle it would not start. The first time this happened, coasted vehicle down slight grade to side of road, and after a few minutes it started again. The second time it happened, it would not start after several attempts. Contacted Subaru though it's starlink program. They told me to hold keyless starter button for 30 seconds, then try to start again. After doing this the car started.

Fresh fuel smell from the vehicle (entering the cabin while driving and upon parking). Upon arriving home yesterday, the smell was still very strong. I went a step further and pulled the oil dipstick to check the level and to see if that's where it was originating from. Sure enough, that is where I am smelling it. I went so far as to wipe off the dipstick and check once again with the same result. I also noted that the oil level is well above the high mark. My main concern is the risk for damage to the engine given that it appears that fuel is mixing in with the oil.

The car will emit white heavy smoke on start. The white smoke smells like burned plastic/oil. The issue was reported to Subaru corporate and vehicle was taken to service for inspection. A video was recorded and sent to both dealer and corporate but issue could not be replicated. The issue still persists for more than 3 months and Subaru could not resolve it. This is a concern to my family safety and to the environment. Second issue was with spring assembly both front and back has to be replaced as defective.

At 16462 miles on odometer, while driving on hi way at 65 mph vehicle lost power and started smoking severely from the tail pipes. Pulled over and shut off. Restarted several minutes later continued to smoke and would not move. Towed to dealer, they stated the PCV valve broke apart, Subaru wants them to tear down the engine to see how much damage was done. Still waiting for them to do anything, car is sitting outside in the service area not being worked on.

My new vehicle has experienced complete electrical malfunction while driving. Vehicle unexpectedly turns on all warnings and disabled all safety features to include collision and blindside monitors. As indicated by many other Subaru owners, the problems were diagnosed by Subaru to be related to a loose transmission harness. So far Subaru has not issued a recall to inspect all 2019 and 2020 Subaru Ascent transmission assembly. We are super scare of driving the vehicle with the idea that it can stall in mid driving.

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.

Almost 9500 miles, raining outside wife driving normal speed (highway driving) and eyesight stopped working and check engine light came on. Vehicle still ran. Secondly took to local subrau dealership for 10,000 service they found nothing wrong and did service. Wife left dealership and noticed car pulling to left after tires rotated. Returned to dealership, they said it was normal feathering of tires. Worried eyesight and engine can be affected with rain. Also at a few hundred more miles we now smell burning oil on and off outside of car. We have also experienced high revving motor with no foot on gas pedal.(stationary when smelling burnt oil smell and motor revving. Also once high revving while my 17 year old was city driving. Love to drive the car, hope it holds up!

Within my first two weeks (200-300 miles) of owning the vehicle I was told by stevens creek Subaru that the car was not safe to drive and here we are again. Another failed strut. So by deduction, it's unsafe to drive but that hasn't stopped Subaru from putting me back in it, fully aware that the strut has failed verified at 20,000 miles but problem started 12,000 miles ago. In motion this is a problem everywhere. Safety issue. Subaru is not making me drive for almost a month with a failed strut, waiting on parts. Let's talk about brakes next... so they replaced the front pads with "special" brakes, hand delivered from Japan. Why" what are these "special" pads and how are they different? I really want to know what's different about these? are they softer? will they wear out faster" I'm not honestly thrilled that they resurfaced the rotors. Again... brand new car... brand new rotors... now they have extra "wear" as a result of the bad brakes from the factory and they will wear out faster. Would have preferred them to be replaced. This only adds additional out of warranty costs to me in the end. Especially if the new pads also wear quicker. Safety we just blindly applied the ECU firmware upgrade with no pre-drive test to verify the problem. Which was why the car was left overnight in the first place initially. So we have no documentation of the issue just that we flashed the firmware. From my tests the past two mornings it seems better and possibly resolved but again, this should have been properly documented and tested and was not. The surging engine condition / transmission gear ratio hunting problem was never verified by the dealer. They blindly flashed the firmware and also didn't road test after the fact. There also still an undiagnosed transmission problem. Additionally there's many more things wrong with my car but your form limits me to three at a time.

I was in traffic and the dash- started flashing and everything at once started shutting off and then brake was applied on its own. Very scary while in traffic- I have been waiting for a tow truck for over 3 hours. Dials: At oil temp flashes, all electronic things is all off and lit. Transmission and braking issues- all at once. City street braddock rd and I pulled off at kings park shopping center in front of wells fargo and cvs, stationary.

Driving on freeway check engine came online suddenly. Eyesight turned off. Car became unstable, could not go past 60 mph. Kids in freking out. Very unsafe. Took to dealership. They could not figure out. I did online research and followed these forums https://www.ascentforums.com/forum/137-Subaru-Ascent-complaints-issues-problems/1981-check-engine-light-11.html apparently early Subaru models had 2 bolts missing in the engine airtight compartment. Atleast 2 other people have complained. I have driven so many miles Subaru as not issued a tsb and a recall. I was planning to take legal action as this a unsafe thing to do. Please please please look into this. I hope you could ensure accountability and honesty w/ Subaru. I am extremely frustrated. Did Subaru deliberately hid this from consumers? please check this forum thread again https://www.ascentforums.com/forum/137-Subaru-Ascent-complaints-issues-problems/1981-check-engine-light-11.html
