Title: Excellent Vehicle, but Persistent Battery Problems Raise Reliab
I purchased my 2025 Hyundai Tucson Limited AWD in November 2024. Overall, I enjoy the vehicle. It’s comfortable, well equipped, pleasant to drive, and offers an impressive range of technology and safety features.
Unfortunately, my ownership experience has been overshadowed by recurring battery and electrical problems.
Within the first 15 months, the vehicle experienced two no-start incidents, both requiring towing at the recommendation of roadside assistance personnel. Despite repeated dealership evaluations, including overnight testing, no definitive cause has been identified.
The battery has repeatedly demonstrated a low state of charge, with documented readings of 49%, 55%, 35%, and most recently 60%, despite passing conventional battery tests. Parasitic-draw testing has also been within manufacturer specifications.
Hyundai Corporate became involved, and the vehicle has been evaluated at two dealerships. Although the service experience has varied, the underlying problem remains unexplained.
More recently, I noticed that the Digital Key proximity feature, particularly through my Apple Watch, repeatedly activated the vehicle’s lights, locks, and sometimes the rear hatch as I moved around my garage. I’ve disabled that feature on the Watch to determine whether it may have contributed to unnecessary electrical activity. This remains a hypothesis, not an established cause.
As a longtime Hyundai owner, I find this disappointing. I appreciate the Tucson’s design, comfort, and technology, but a vehicle’s most fundamental responsibility is to start reliably.
I hope Hyundai ultimately identifies the problem. Until then, my confidence in the vehicle’s long-term reliability remains diminished.
