Just bought brand new 2026 Subaru Uncharted GT, noticed the headlights flicker or shake a lot while driving especially when going over slightly bumpy roads. Itâs very distracting to me as a driver and I would think to other drivers in front of me or opposing drivers. No specific lights or warnings come on when this happens. I have read online that many drivers have the same issue with their Subaru.

SUBARU UNCHARTED 2026 EXTERIOR LIGHTING

Since 2023 starting with the Subaru Solterra and Toyota Bz4 and now in 2026 both companies have 3 models each. Toyota builds all of them for themselves and Subaru. If you do not drive these cars daily the 12 volt batteries go dead. Subaru and Toyota has continuously denied a problem and advises owners to jump it themselves or connect a battery maintainer hoping to sweep this dangerous problem under a rug. It is dangerous that can leave you stranded or if you need to go somewhere right away you can't. If you do a google search or Reddit search about 12 volt dead batteries on Subaru Solterra, Uncharted and Trailseeker you will see hundreds of complaints and with Toyota the Bz4, Bz, CH-R. Both companies deny there is a problem. My own 2 month old Subaru Uncharted was parked and not driven for 3 days and the 12 volt battery was dead and I called Subaru Roadside Assistance and he jumped it and stated it was at 3 volts, he said he has jumped a lot of Toyota EV's I thenI drove the 35 miles to the dealer and it charged while driving and it passed the test, if it was towed it would have failed but I had no way to get to the dealer. On the invoice the tech wrote "Tested 12v battery. Battery passed. Use of trickle charger if vehicle won't be driven for days is recommended". That is not an answer, it needs to be fixed with ALL Subaru and Toyota EV's. If you park outside then how to connect a trickle charger, you go on a vacation and park in a public lot and come back to a dead battery after a week. Please investigate this. There are classaction lawsuits for the 2023-2025 now and am sure the 2026's will be added. Owners are documenting everything and doing lemon law buybacks. Subaru and Toyota needs to be held accountable. In my opinion the problem is with the Battery Management System,ALL other EV's monitor the 12 volt battery voltage and when it falls to a set level the high voltage battery charges it but not Subaru or Toyota it does not monitor the voltage.

It is an EV, the 12 volt battery went dead after sitting 3 days. Problem is all other EV's charge the 12 volt when the voltage goes below a certain level, while the Subaru only charges the 12 volt while driving and if parked then it is on a timer and only every 20 days. I have attached a copy of the service manual someone posted. This is unsafe. Only have the car purchased new May 24, 2026. Complaints all over the internet especially on its Toyota twin the BZ as more of those sold.

Headlights (high & low beams) bounce as if loose when hitting any sort of uneven road surface. Edges of light almost appear to flicker when this is occurring which is anytime headlights are on and car is moving. Extremely distracting and creates uncertainty when driving in rural areas.

Headlights visibley shake when the car encounters a bump in the road, during braking, and anything else that can create an impulse on the car. The vehicle is available upon request for inspection. It creates a distint and distracting event that is distracting to the operator when and potentially on-coming traffic when driving at night.  I have heard that others have also verified this with dealers, but I have not personally had the opportunity to bring it to mine.  The problem in my personal vehicle has not been inspected by any authority, I have just purchased it.  There are no warning lights or symptoms as this appears to be a mechanical mounting issue that is unmonitored by the computer.
