Key Points

  • Subaru has recalled certain 2017 Subaru Foresters due to faulty wiring in an airbag sensor. The issue of airbags potentially not deploying in an accident has led to the 2017 Forester’s single NHTSA investigation.
  • Some NHTSA complaints report 2017 Subaru Forester models lunging forward when stopping in traffic or parking. The problem has reportedly caused minor accidents, like jumping curbs and hitting parked vehicles.
  • Another commonly reported complaint pertains to the 2017 Forester’s weak windshields that reportedly crack easily, sometimes on their own. Also, recent complaints mention parasitic battery drain that may lead to batteries needing to be replaced.

2017 Subaru Forester’s One NHTSA Recall also Launched an Investigation into Faulty Airbags that may not Deploy

The 2017 Subaru Forester has only one active recall, and it is cause for concern. Subaru recalled certain 2015-2018 Foresters equipped with heated seats, due to faulty wiring in an airbag sensor. If the wire’s connection loosens, the front passenger airbag may deactivate even though the seat is occupied, increasing the risk of injury in a crash.

Although the recall pertains to the front passenger airbag, additional issues with airbag deployment appear in nearly 100 NHTSA complaints from as recently as Sept. 2021. Various reports from 2017 Forester owners mention accidents where the front passenger airbag did not successfully deploy. Some owners allege that it was not only the front passenger airbag that failed in a high-speed collision, but all of them.

NHTSA’s Office of Defects Launched 2019 Investigation into Airbag Issue

In Aug. 2019, the NHTSA’s Office of Defects began to investigate complaints and allegations of front passenger airbag system malfunctions in model year 2016 through 2018 Subaru Forester vehicles.

The airbags in vehicles including the 2017 Subaru Forester rely on an occupant detection system that reportedly failed to operate properly and incorrectly turned off the front passenger airbag even though the seat was occupied, increasing the risk of injury in the event of a crash.

NHTSA’s analysis of the complaints showed that most of the complaints involved vehicles with seat heaters. Subaru instructed owners with Foresters produced in the affected production range to head to a dealer to have the sensor mat harness inspected and replaced, if necessary.

Weak Windshield Prone to Easy Cracking Consumes Nearly 20 Pages of Owner Complaints

There are currently 370 consumer complaints registered with the NHTSA, with the majority of them focusing on three different areas: visibility, electrical system, and engine/powertrain. The problem with visibility seems to be a widespread and serious problem and stems from a windshield that reportedly cracks easily and often without even being impacted by anything.

Some 2017 Subaru owners mentioned having to replace their windshield more than once due to it cracking either on its own or after being struck by a small piece of road debris. One owner says his windshield cracked after being struck by a “small piece of debris no larger than a nickel.”

Considering the prevalence of complaints about the weak windshield, which takes up 18 pages on the NHTSA website, you’d assume a recall or investigation is warranted, yet none has been issued.

“I have replaced my windshield a second time in a 30-day period,” laments one 2017 Subaru Forester owner in an April 2021 complaint. “I had my windshield break while I was driving, and I did not see anything hit the windshield. As soon as I got it replaced, three days later, I woke up to see that my windshield was broken again. Nothing hit the windshield either time, and it just sporadically cracked.”

As unusual as the experience seems to be, countless complaints repeat the same windshield scenario almost verbatim, with another owner writing in March 2021: “Forester windshield started cracking for no clear reason, spread quickly to a 20″ or longer crack that continues to spread.”

Nearly 400 Consumer Complaints Address Engines Stalling, Fuel Odors in the Cabin, and Random Acceleration that Led to at least One Fender-bender

The 2017 Subaru has nearly 400 consumer complaints, and the majority of them–nearly 100–pertain to airbag issues and range from innocuous to serious, with some consumers reporting that they were in bad accidents and the airbags failed to deploy.

Other individual complaints noted exhaust fumes in the cabin, and loss of power while driving up small hills or when accelerating on the highway. A common complaint from many 2017 Subaru Forester owners was the frustration of having their keys get stuck in the ignition barrel once the vehicle is off. The complaints first appeared as far back as September 2019 and have even been addressed on Subaru Forester owner forums.

Among the most serious complaints are reports of vehicles continuing to accelerate after drivers remove their foot from the gas pedal. One owner reported the same scenario happening while he had his foot on the brake. In a March 2021 complaint, he said, “while pulling into a parking space, the vehicle surged forward when the brake pedal was depressed, causing the vehicle to jump a cement bumper and the bushes in front of the vehicle. The vehicle was still revving when turned off and placed in park.”

Another 2017 Forester owner echoed a similar situation, mentioning “pulling into a parallel parking space, braking slowly to a stop when my car surged forward in spite of increased and continued braking, and I hit the car in front of me. The collision is what stopped the car.”

Although the consequences have been relatively minor, the unintended acceleration issue has already led to a class-action lawsuit, alleging that faulty circuit boards and electronic components may be responsible for the acceleration problem.

Newest Owner Reviews of 2017 Forester Claim Electrical Issues may Cause Excessive Battery Drain

More recently, complaints about 2017 Subaru Forester models suffering from excessive battery drainage have been surfacing. Some owners reported that their 2017 Forester had to have multiple battery replacements with fewer than 50,000 miles on the vehicle.

“The battery on my 2017 Forester has been replaced under warranty three times after being found dead,” said one owner in a May 2021 complaint. “All three times Subaru has said it was a bad battery, and my mechanic said it was an electrical issue if it happened more than once.”

Another owner said, “the battery of our 2017 Subaru Forester has died three times from June 26, 2021 through August 20, 2021. Simply put, from one day to the next, the battery is suddenly drained of all its power.”

Many owners confirmed Subaru replaced the battery under warranty, but 2017 model year Foresters are no longer eligible for Subaru’s three-year/36,0000-mile warranty. So, battery replacements would now be the financial responsibility of the vehicle’s owner.

Numerous problems
2017 forrester. Have had hesitation on Excelleration. Have had this problem since vehicle was 6 months old. Dealer does not know how to fix. They tried to say I needed rear brakes two years ago! Brakes are still fine! 55,000 miles so far. Had to replace battery at 2 yrs. Passenger seat heat works periodically. Recall says they fixed it! Still doing same thing. Tires not good quality. Had to replace at 38,000 miles. I am 82 yrs old and drive conservatively. Had the windshield replaced because of small crack last year. Really like height of vehicle because of back prob. Windows are large and that makes viewing all around easier.

Electric issues with FORESTER
I have had issues with my driver side window motor as well as issues with the headlights not shutting off. Connection issues with the Bluetooth or steering wheel buttons. And delayed reaction with the trunk when pushing the automatic buttons since you cannot pull it open.

Bits and pieces go wrong sometimes.
Air conditioner had leak within one year-under warranty. The passenger side window does not work. The driver side window occasionally gets stuck. There has been a recall which I cannot afford to take a day off to get fixed. Clutch slips out of reverse.

2017 Forrester rearview mirror fell off
I had one problem initially - the rearview mirror literally fell off the windshield and hung in the air. The dealer didn't respond quickly and I drove around like that for weeks, which was dangerous and inconvenient.

Tire sensor and phone interference
I had one issue with it which was the tire sensor kept lighting up. My service at the dealership finally determined that my charging cable for my phone needed to be shielded. Once I purchased one, the issue stopped.

Electric issues with 2017 Forester
The only problem I have had with my car is that within the past 3 months, the switch on the driver side that operates the front passenger window has failed, while the switch on the front passenger side still works.

AC left me hot during summer
The only issue I had was getting a part to fix the air conditioning. It took 3 months before the part came in and I was without air conditioning for a whole summer in my 2 year old car because of this.

2017 Subaru forester likes to stall
Has a hot restart problem where it almost stalls completely when pulling out. I have to think fast and floor it so the it does not stall out. It happens mainly in extreme temps. Could be fatal.

My 2017 forester daily driver
The only issue is that the air conditioner failed after 3 years. Luckily, there is an extended warranty for the condenser so I was able to have the unit completely replaced by the dealership.

Too expensive for the quality.
At only 3 years old the exhaust system has a problem. I will not buy this car again. The brakes have been done already too. It just does not seem the quality I was expecting.

Difficult to change lights and few mechanical issues
I have had to replace a headlight and turn signal, which was very challenging with the a support bar, battery, and washer fluid reservoir needing removed to get to the bulbs.

AC Issues
I have had three, yes three AC failures in two years. One condenser, one compressor, and one valve. That has involved many trips to the dealer for diagnosing and fixing!

2017 Forester, watch out for the minor glitches.
Had loose wires in causing dash light to stay on. I would think a new car would not have loose wires.
