Brought in they gave me loaner 12 days later on 3/18/2026 pick up car. Paid bill they told me everything done no problems. I would get my 250 dollars for the car back in 30 days.

Arrived at 4 40 pm Chris service Advisor check said was not save to drive burning smell still there got another loaner another 200 dollar on top of the 250. Called saburu customer advocacy this morning spoke to Latoya 11 15 am 3/20/2026 case number XXX-XXX waiting for someone to call me by Tuesday. I requested a 3 year gold plus warranty as a goodwill gesture to restore my confidence in the vehicle and protect my engine integrity. I am deeply concerned that the gushing coolent damaged the internal engines seals or may have been compromised due to the heat, the hoses or gadgets now or over time. I have puctures and documents that the system won't allow download. If the car continues to have reoccurring issues due to this complete repair failure. I am asking them to replace my 2018 saburu crosstrex that has only 52, 315 miles with an equal value car without issues. My car is 10 years old low mileage. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

All four tire pressure monitoring sensors failed on my 2018 Subaru Crosstrek at approximately 69,000 miles. The TPMS light remains illuminated, and the system no longer provides low-tire-pressure warnings. Subaru of America acknowledged the issue but declined full repair coverage, offering only partial “Goodwill assistance.” Because TPMS is a federally mandated safety system, a full-system failure poses the risk of operating the vehicle without tire-pressure warning capability. The dealership quoted approximately $1,000 to restore the system. Subaru’s decision to deny full coverage leaves the safety defect uncorrected.

factory alarm is triggered late in the evening while in my garage regardless if vehicle is locked or unlocked

Hello, My subaru crosstrek 2018 has been brought to Subaru service departments in both CA and MA for the same issue. I have brought in my car 3-4 times for recurrent problems where the battery in the car dies. The battery has been replaced multiple times and I have brought it to Subaru Service departments both in Massachusetts and California, all of whom tell me that the battery needs to be replaced, over and over again. I called and filed a report with Subaru of America who directed me to a third party representative who deals with claims regarding subarus and their recurrent battery issues and was informed that my subaru is not eligible for reimbursement for recurrent issues with batterys, nor is it a model that is eligible for an extended warranty given the battery issues. This is a huge safety issue for me. I have found myself in empty parking garages at night with a dead battery where I have had to stay locked in my car while I call a tow/AAA service to come and jump my car. I have missed countless days of work due to this issue. I have been late to pick up my child from daycare. I have spent thousands of dollars missing work, getting ubers while my car is in the shop, using rental cars, calling tow companies while this issue has been ongoing for two years. In addition, I have spent hundreds of dollars on portable battery chargers so that I do not get stranded with a battery-less car. I have raised this issue to the Subaru service departments multiple times, as well as Subaru of America with no solution.

Was told I needed a new ecm due to corrupt learning. My vehicles check engine light, traction control light, and cruise control all turned on/ stopped working. My vehicle has received all necessary maintenance in a timely manner, no missed oil changes and no accidents. The dealership stated it was due to damage but this can’t be possible since the only place service has been completed was at the dealership, if it was damaged it would have been caused by the dealership. I have seen multiple threads online stating the same issue with their vehicle same model and similar years and the cost to replace is not cheap.

I noticed that my 2018 Subaru Crosstrek battery keeps draining when the car sits for several days (something that typically has not happened in the past until my son recently went off to college). I called AAA and they checked out the battery and indicated that the battery was good still, but was borderline. Would likely need to be replaced soon. Since it was the original battery and it would need to be replaced soon - I had them replace it. Even after the battery replacement - the battery drains when the car sits for a few days. I took the car in to my local Subaru dealer and they indicated parasitic drain from DCM is depleting the battery. They tried performing a factory reset on the DCM, but it was unsuccessful. The dealer quoted me $1200 to replace the DCM and had to order it. I also noticed several class-action lawsuits for other Subaru models (which sound like the same issue). I called Subaru Customer Advocacy to inform them of the situation and currently awaiting a response.

Premature starter failure as noted in TSB 07-198-21 due to failed clutch in starter motor. Only had 35, 750 miles. Defective starter. Issue known to Subaru. Could leave drivers stranded and at risk. This known/ common starter motor failure problem should be a recall.

the horn quit working, everything else on my steering wheel and steering column work just not the horn, no way to warn approaching traffic, safety issue, puts myself and family in harms way.

Battery drain when car isn’t in use for 2 days went through 3 high CCA AGM batteries since I purchased new. also the manufacturer OEM battery. I only have 16,400 miles on the car and went through 4 total batteries. I had to pay for all the batteries and now I need another one.

BATTERY ISSUES

Purchased NEW car 2018 and ALWAYS serviced at dealership. No problems until January 2022, radio issues. Dealer replaced radio - ever since then, the battery of the car keeps dying. The radio was replaced at least 3 times. Approximately Jan 21, 2023, I had to pay to replace the battery because service department said it needed to be replaced. Jan 23rd, the car was dead in my garage - they replaced the battery. On Jan 27th, car was dead again in the garage. Dealer had car towed and they kept until Jan 31st, when they had a “specialist” from Tampa look at the problem - another battery. Oct 3 again dead in the garage. Even the TEO KEYFOBS has to be replaced as they were drained of power. There obviously is an ELECTRICAL PROBLEM somewhere in the engine and we are afraid that the car might stop running WHILE I AM DRIVING IT, or AIR BAGS DEPLOY or maybe an ENGINE FIRE. THERE IS A SERIOUS ELECTRICAL ISSUE WITH THE VEHICLE. I reported it to Subaru Corporation and their executive said to “just keep bringing it in when the battery has died”! How does that resolve the electrical POTENTIALLY UNSAFE ISSUE? As of today, 11/12, in the evening you can see on the radio screen a type of “glow” or “backlight” coming from the screen WITH THE RADIO TURNED COMPLETELY OFF. We are seniors who are not afraid to drive this car because of potential safety issues or being “stranded” somewhere if it is not operational. I contacted Subaru Corporation and all they will do is issue a “goodwill” credit of $1,500 toward a new car. We are retired and on a fixed income and thought this would be our forever car and even purchased the extended warranty to avoid any future expenses that we could not afford. It would be an unbudgeted expense to pay for another vehicle.

The contact owns a 2018 Subaru Crosstrek. The contact stated while driving at approximately 50 MPH, the vehicle lost motive power and stalled. While driving on a ramp at slow speeds and depressing the accelerator pedal, the vehicle failed to accelerate and stalled. There were no warning lights illuminated. The vehicle was towed to the local dealer to be diagnosed. The contact was informed that the ignition fuse needed to be replaced. The fuse was replaced, and the vehicle was repaired. The manufacturer was contacted but provided no additional assistance. The approximate failure mileage was 39,000.

The contact owns a 2018 Subaru Crosstrek. The contact stated that after a heavy rain and starting the vehicle several warning messages appeared on the instrument panel such as the assist braking and eyesight driver assist needed servicing. The contact also stated that the steering wheel was hard to maneuver. The vehicle was taken to the dealer who stated that a sensor in the wheel caused the failure. The sensor was replaced however, the failure reoccurred after heavy rains a month a later. The vehicle was taken back to the dealer who stated that the failure reoccurred due to the computer sensor in the rear driver’s side wheel that was replaced was not reset. The contact stated that in December water was noticed on the driver’s side floor and condensation after a heavy rain. The vehicle was taken to the dealer again where the failure was diagnosed as clogged sunroof draining ports. The contact stated that the sunroof port needed to be replaced and unclogged. The manufacturer was notified, and a case was opened. The approximate failure mileage was 32,000.

EYESIGHT SWITCHES ON AND OFF TOO OFTEN FOR NO OBVIOUS REASON WHEN THE VEHICLE IS IN MOTION REGARDLESS OF A CITY STREET OR ON THE HIGHWAY

WE CAN DRIVE HUNDREDS OF MILES, MAKE A FEW STOPS AND DURING ONE OF THOSE STOPS, THE BATTERY IS DEAD. THIS HAS OCCURRED THREE SEPARATE TIMES OVER THE LAST 4 WEEKS. WE'VE HAD THE VEHICLE AT JOHN KENNEDY SUBARU IN NORRISTOWN WHERE THEY ATTEMPTED TO DIAGNOSE THE PROBLEM. WHAT THEY DID WAS PERFORM AN UPDATE ON RADIO AND THE BATTERY, STARTER AND ALTERNATOR ALL CHECKED OUT OK. THE CAR DIED AGAIN TODAY AND WE'RE SCHEDULED TO BRING IT IN AGAIN ON MONDAY.

The battery in my Crosstrek inexplicably drains and sometimes won't hold a charge. I've had to buy a charger/booster after replacing the battery twice. 7/20/2020 and 9/18/2020

IN NOV 2017, AT 700 MILES, I HAD A REMOTE START INSTALLED AT THE DEALERSHIP. IN MAY 2018, MY REMOTE START WOULD NOT START THE CAR & WHEN IT WOULD THE CAR WOULD STALL. EVEN WITHOUT THE REMOTE START MY CAR WOULDN'T START OR IT WOULD START AND SHUT OFF. I COULDN'T GET IT TO FUNCTION FOR 3 DAYS. IN ADDITION, I WAS HAVING ISSUES WITH MY RADIO. THE RADIO WOULD FREEZE UP OR IT WOULD NOT TURN OFF, THERE WERE TIMES THE RADIO WOULD KEEP RUNNING FOR CLOSE TO 15 MINUTES EVEN THOUGH THE CAR WAS SHUT OFF. I TOOK MY CAR TO DEALERSHIP IN MAY 2018 AT 4136 MILES & THEY STATED MY TERMINAL CONNECTIONS WERE LOOSE, THEY COMPLETED A RADIO UPDATE & THAT WHEN THE REMOTE START WAS INSTALLED THEY DIDN'T BELIEVE IT WAS FULLY CONNECTED TO THE BATTERY. SHORTLY AFTER, MY GPS WOULD LOSE CONNECTION A LOT, MY EYE SIGHT TECHNOLOGY SHUTS OFF WHEN I'M DRIVING IF IT'S FOGGY OR RAINY, MY REVERSE AUTO BRAKE HAS STOPPED MY CAR EVEN THOUGH THERE WAS NOTHING BEHIND ME, MY CAR AUTO BRAKED ON THE HIGHWAY TWICE EVEN THOUGH I WAS NOT NEAR ANYONE & ALMOST CAUSED ACCIDENTS, & MY RADIO HAS FROZEN UP, SO I COULD NOT DO ANYTHING BUT VIEW A BLUE SCREEN WITH WHITE STARS. I KEPT GETTING CHARGED FOR STARLINK BUT IT NEVER WORKED, THE ICONS WOULDN'T EVEN LIGHT UP ON MY SCREEN FOR IT. I BROUGHT MY CAR IN FOR NUMEROUS RECALLS IN FEB 2020, MY CAR HAD 13,790 MILES. ON MAY 20, 2020, MY CAR WOULD NOT START; MY KEY FOBS & REMOTE START WOULDN'T WORK. A JUMPER BOX COULDN'T START MY CAR; I HAD TO HAVE SOMEONE JUMP THE CAR. THE CAR RAN ROUGH & THE ODOMETER SHUT OFF & THE SCREEN CHANGED WHILE DRIVING. TODAY, THE CAR IS DEAD AGAIN. I CAN ONLY GET INTO MY CAR WITH EMERGENCY KEY, THE CAR & ELECTRONICS WILL NOT TURN ON & LIGHTS WERE BLINKING ON THE DASHBOARD. MY CAR HAS 17,132 MILES & THIS IS THE 2ND TIME I AM COMPLETELY WITHOUT A CAR FOR DAYS. THERE IS SOMETHING SERIOUSLY WRONG WITH THE BATTERY & ELECTRICAL COMPONENTS OF THIS CAR. *TR
