    ... transmission and the car got moving once again, but the replacement unit was very jerky and the car would have bucking fits. My wife and I didn’t want to drive this car as it was finicky and we didn’t know if it would make it to our destination and back given the ongoing transmission issues and then newly cropped up engine/fuel pump issues. Also, the rear hatch would sometimes work, sometimes wouldn’t open. There were other smaller issues such as wind noiseRead More

Subaru continues showing a strong focus on multi-role vehicles that can adapt between daily commute and touring. The Subaru Ascent follows the same lines. The SUV also makes for a good option as a family vehicle. The SUV registers 3 recalls and 188 complaints for the 2020 model year. The problems with the SUV range from parasitic battery drains to driver aid defects. However, the car manages to earn a 5-star safety rating. Subaru typically offers prompt and reliable after-sales services. Which is a piece of good news for the potential buyers. The Ascent shares the market space with the likes of the Ford Explorer, the Toyota Highlander, and the Mazda CX-9. The car finds the 6th spot on the CarHp list of top 10 SUVs for 2020

User Complaints and Problems

Mechanical Problems

  • Brakes - The 2020 Subaru Ascent comes across a few braking issues. Users report the car shuddering with heavy vibrations during the application of brakes. Few cases report instances of brake failure. Users depress the brake pedal but the brakes do not engage. Few users also report cases of rogue acceleration while applying brakes. This compromises the safety of the user and the vehicle. This also increases the chances of crashing.
  • Powertrain - Most powertrain issues with the Ascent relate to the transmission and gearbox. The SUV gearbox tends to jam in the ‘park’ mode. This prevents the shifting of gears. Users also report gear-grinding and the SUV lurching forward from a complete stop. These powertrain issues are time-consuming and financially demanding.
  • Fuel Pump - Fuel pump failures are common to Subaru Ascent users. Fuel pump failures result in vehicle stalling. 

Electrical Problems

  • Battery - Parasitic Battery drain is the most common problem with the Subaru Ascent. Customer complaints report rapid battery drains with the SUV when parked. This requires jump-starting the car or replacing the vehicle battery.
  • Engine - Engine stalling is common with the Subaru Ascent. Under driving conditions, engine stalling can result in a drastic loss of speed. This is due to a loss in drive power. This abrupt drop in speed increases the chances of a crash. 
  • Driver aids - Driver aid defects are common to the Subaru Ascent. Forward collision avoidance malfunction fails to recognize incoming obstacles. This results in crashing. Auto Emergency Braking malfunctions fail to apply brakes under emergency scenarios. This too increases the chances of crashing.

Structural Problems

  • Windshield - Shattering or cracking of the windshield is a common issue for Subaru Ascent users. Subaru claims the environmental temperature changes to be the cause of the issue.
  • Body frame - Few user complaints report the SUV hood wobbling under driving conditions. Users also report a few cases of water leakage in the vehicle cabin due to poor insulation.

Safety Problems

  • Airbags - The SUV is prone to airbag deployment malfunction. This increases the chances of injury and compromises user safety.
