Selected complaints filed with NHTSA by 2016 Subaru Crosstrek owners, lightly cleaned up (personal details are redacted by NHTSA).
I have a 2016 Subaru Crosstrek. Unfortunately I have had a couple of issues. The main thing being the horn. The location of the problem is affecting my air bag, AND my rear window defroster. I don't know if Subaru has a faulty clockspring and relays, that malfunction after a certain amount of time. But for everyone's safety, it would seem that the Subaru Corporation would implement a recall. As a result of the horn not working, I was involved in a fender bender accident, I was unable to alert a driver that they were merging into my lane of traffic. I've searched mechanics and auto parts stores, the cost is exorbitant, especially for a senior on a fixed income. I don't know to whom these reports are or if they are forwarded, but I certainly hope someone in a decision making capacity will help the loyal owners of Subarus. …
The contact owns a 2016 Subaru Crosstrek. The contact stated that while coming to a stop at a traffic signal, the vehicle was idling roughly. The contact stated no warning light was illuminated. The contact stated that the failure was intermittent but had become a recurring failure. The contact stated that the failure occurred frequently whenever the A/C was running. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the throttle body needed to be cleaned. The vehicle was repaired. The contact stated that the failure returned, and the vehicle was taken back to the same dealer who diagnosed the vehicle and determined that the alternator and belt tensioner needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 32,000.
Car caught fire from what seemed to be an electrical issue. Car became engulfed in flames within a few seconds. Fire department was called to extinguish the fire. I was lucky myself to make it out in time. The fire became so big, so quickly, I was concerned for the safety of the surrounding property. Luckily, no one was injured and no property damage took place. Car was inspected and totaled by insurance. The headlights were constantly needing to be changed. Otherwise the car was fine. I had just replaced the battery and just a few hours later the fire happened. The fire appeared to start somewhere under the hood on the passenger side.
I own a 2016 Subaru Crosstrek with only 37,000 miles. There is a problem with my battery being drained after not driving the car for several days. I have had to call for a jump start 3 times, Aug. 8, 2023, Sept. 5, 2023 and Nov. 14, 2023, each time after returning from vacation. I replaced the battery when it happened the second time, but the problem continued to occur. I have taken my car to the Subaru dealership for diagnostic. They checked the draw level in the vehicle electric system found excessive draw of 350MAH when everything was turned off. The performed DCM (data control module) check and disconnected the fuse. The draw dropped down to 15MAH. I was told I could leave the fuse disconnected, which would leave me with a useless navigation system, loss of front speakers and bluetooth, or replace the DCM that would cost me around $1000. …
On Jan 7th, during rush-hour traffic on the highway, without any warning all of my vehicle lights began to dim. The power steering and brakes went out. I was able to steer to the side of the road. Then, all of the lights went out and the car shut off. I was unable to shift the vehicle into park, and as I was going up a hill at the time, I was forced to roll backwards slowly and engage the emergency brake. Only luck prevented a serious, perhaps fatal accident. It was also below freezing in Ohio so I had to sit in the frigid temperatures until a tow truck arrived. After being towed to two separate dealerships, the Subaru dealer believes this was caused by a faulty hybrid battery, alternator, or both. An inspection is available by request. …
2016 Subaru Crosstrek 2.0 LTD (CVT) When placing vehicle in park, occasionally, will not allow me to remove ignition key when transmission is placed in park position. Safety issue is that I am not able to exit vehicle because if they remains in the car, it will be an easy vehicle to steal. Especially an issue if I am in a parking lot at night or during severe weather conditions. The car dealer and Subaru of America feel that it is my financial responsibility even though there are numerous other Subaru Crosstrek owners that have voiced the same complaint. Subaru has issued several service bulletins acknowledging that there is a defect and that the shifter was redesigned for model year 2019. Subaru Service Bulletin 16-112-18R states "The cause is contamination if the Park-Range switch internal components.
I had to have it be jump-started first on 7/20/21 and again on 7/23/21, the battery had been replaced with a new manufacturer's battery in Feb. of 2020. When the battery didn't start on 7/23 there were several warning lights concerning all the electrical safety systems. AAA came again this time jumped it and it started and I had it towed to the dealership. Since it was towed to the dealership I have learned that this is a documented problem with this car and that there was even a service bulletin put out by Subaru about how to deal with the problem, their fix is to replace the battery but that is fixing the symptom but not a cure. I was told that I should report this to your agency.
Since at least 2009 all Subaru models have a faulty air bag Clockspring. The horn doesn't work due to this. Subaru knows about this issue. Even 2018 Forester is still using the faulty clock spring. We almost had an accident because the horn didn't work. After researching the issue, I cannot believe a recall has not been issued. Tried to get it fixed at Subaru today. Still not fixed. We cannot drive until the horn is fixed it is dangerous driving in [redacted] and not having a horn to give a warning when you are about to be hit.
A/C Control Head and connector burned on both ends. Dealer service center stated it was a significant safety/fire hazard if we had not immediately taken in to be checked. No warning, no fuses out. Only indication something was wrong is a/c turned on but only on 1,2 and 4. Then, same day, only on 4. Next day took to Subaru service center. When we asked how would replacing parts stop this from happening again, we were told original parts had a "Design Flaw" and was "Defective". Replacement/New parts wiring system actually corrects the OEM defect.
Ignition Key stuck in the ignition cannot be removed from ignition after parking. This problem never occurred in previous 5 years of ownership. It happens nearly every time the car is driven, and has been reported widely on the internet by Subaru owners. In many cases, owners have not been able to remove the keys at all, and have had to call for assistance. On the advice of a repair tech, we replaced our battery, which, at 5 years old, was probably due to be replaced. This has not solved the problem.
