What is the most common problem with the Subaru Ascent?

Common Problems with the Subaru Ascent
The Subaru Ascent has experienced several common problems reported by owners and documented in various sources. Some of the most frequently reported issues include:
1. Denso Fuel Pump Failure:
– The impellers inside of Denso branded fuel pumps may have been excessively exposed to a drying agent during manufacturing. This leads to them cracking, absorbing fuel, and deforming so badly that they stop sending fuel to the engine.
2. CAN System Parasitic Drain on the Battery:
– Many owners of newer Subaru vehicles have experienced dead batteries due to a parasitic drain on the battery, with the main cause being the CAN system.
3. Engine and Powertrain Issues:
– Random engine stalls, check engine warning lamps, thick gray smoke from the tailpipe, and sudden loss of power have been reported as common powertrain complaints, often caused by a faulty low-pressure fuel lift pump in the fuel tank .
4. Battery Drain:
– Premature battery drain has been a widespread problem, leading to class-action lawsuits against Subaru. This issue has been reported across multiple model years, with allegations of batteries draining prematurely.
5. Windshield/Rear Glass Cracking:
– The windshield, specifically on the 2019 to 2021 model years of the Subaru Ascent SUVs, has been reported to crack without notice, constituting one of the most common structural faults in the SUV.
6. Electrical Issues:
– Electrical problems resulting in dead batteries have been common since the vehicle’s introduction, with reports of open tailgates draining the battery and other electrical system malfunctions.
It’s important to note that while these issues have been reported, the severity and frequency of these problems may vary among individual vehicles. Additionally, it’s worth considering that the 2022 Subaru Ascent models have reportedly shown improvements in addressing some of the previously reported issues.
