2018 SUBARU CROSSTREK Electrical System Problems

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.

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...

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...

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...

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.

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.

-driving at moderate pace between 30 and 40 mph when vehicle engine shut off without warning. loss of power, no steering and all warning lights illuminated. difficulty getting vehicle over to side of road so not in way of traffic. braking was difficult once on side of road.

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.

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.

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.

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...

AFTER BEING PURCHASED ON APRIL 4TH, 2018, WITH 125 MILES ON THE VEHICLE, I RAN THE VEHICLE ROUGHLY 2000 MILES, AT WHICH TIME MY VEHICLE BEGAN HAVING MAJOR ISSUES. THE FIRST OCCASION, I WAS DRIVING IN BUMPER TO BUMPER STOP AND GO TRAFFIC ON I25 IN DOWNTOWN DENVER, I STOPPED THE VEHICLE WITH TRAFFIC, AND AT THAT TIME THE CAR HAD A "COMPUTER MALFUNCTION" AS I WAS TOLD BY THE DEALER, ESSENTIALLY KILLING MY CAR, LEAVING ME STUCK IN THE CENTER LANE OF A 5 LANE HIGHWAY.

SUBARU'S SAFETY SYSTEM EYESIGHT THAT USES ACROSS MULTIPLE MODELS INCLUDING MY 2018 CROSSTREK HAS A SERIOUS PROBLEM THAT PREVENTED THE HUMAN DRIVER TO BE ALERTED. THE EYESIGHT SAFETY WARNING AUDIO ALERT DOES NOT INTERRUPT THE AUDIO FROM THE RADIO UNIT, IN ADDITION THE AUDIO WARNING SOUND LEVEL IS VERY LOW DESPITE THE MAX SETTING ON THE SYSTEM. MY CELL PHONE'S RINGER VOLUME IS MUCH LOUDER THAN THE SUBARU'S EYESIGHT VOLUME. DURING THE NORMAL MUSIC LISTENING I CAN'T EVEN HEAR THE SAFETY WARNINGS (REAR CROSS TRAFFIC, FORWARD WARNING, AND LANE ALERT ETC). THIS CREATE AN EXTREMELY DANGEROUS DRIVING ENVIRONMENT THAT MIGHT LEAD TO AN ACCIDENT. MY CROSSTREK DOES NOT HAVE AN ADDITIONAL WINDSHIELD VISUAL ALERT LIKE MY GM CAR THAT HAS A RED LED PROJECTED TO WINDSHIELD IN ADDITION TO AUDIO ALERT. BY THE WAY GM'S ALERT STOP THE RADIO AND THE VOLUME IS LOUD. MY PROBLEM WAS CONFIRM BY DEALER...

HEAD UNIT FREEZES. CANNOT ADJUST RADIO VOLUME OR CHANGE STATIONS. MUST SHUTDOWN VEHICLE FOR A FEW MINUTES TO ALLOW COMPUTER TO REBOOT. VEHICLE IS IN MOTION WHEN THIS SITUATION OCCURS.

UPON STARTING THE CAR, THE RADIO BLARES AFTER A FEW SECONDS, WHEN BACKING UP, FOR INSTANCE, REGARDLESS OF WHETHER IT HAS BEEN TURNED OFF. ACCORDING TO SUBARU, THAT'S THE WAY IT'S DESIGNED. I THINK ITS A SAFETY HAZARD, AS THE FIRST MOMENTS WHEN DRIVING CAN REQUIRE SPECIAL ATTENTION (WHEN BACKING UP, FOR INSTANCE), AND THE RADIO BLARING WITHOUT WARNING CAN BE DISCONCERTING AND JARRING. CAN THIS BE CONSIDERED A DESIGN FLAW, AND THE VEHICLES WITH THIS NEW SYSTEM RECALLED?

PURCHASED NEW 2018 CROSSTREK WITH HARMAN KARDON PREMIUM AUDIO SYSTEM. AFTER ONE WEEK THERE WAS A CONSTANT STATIC BUZZ COMING FROM THE DOOR SPEAKER ON THE PASSENGER-SIDE, EVEN WHEN THE AUDIO SYSTEM WAS TURNED OFF. DEALER SAYS THAT THEY NEED TO REPLACE THE AMPLIFIER.
