Cars have more tech than ever — and drivers are increasingly frustrated with their door handles, screens, and other features

• The more high-tech a car is, the more problems it has.

• The auto research firm JD Power assessed dozens of vehicle brands for its latest quality study.

• Tesla landed the second-worst brand in terms of quality, while Dodge took the crown.

As cars become flashier and more technologically advanced, they're getting more problematic, too.

The overall quality of new vehicles is deteriorating and nagging problems are on the rise, according to a new study from JD Power. The auto-industry research firm said more technology in cars is partially to blame.

"From persistent problems carrying over from years past to an increase in new types of problems, today's new vehicles are more complex — offering new and exciting technology — but not always satisfying owners," Frank Hanley, senior director of auto benchmarking at JD Power, said in a statement.

JD Power analyzed more than 93,000 owner and lessee responses to its 223-question survey that assessed the quality of nine categories including everything from a vehicle's infotainment, interior and exterior, controls and displays, and driving assistance. Those surveyed were all driving 2023 model-year vehicles.

What are the biggest issues?

Quality declined year over year across all categories apart from driving experience. The two categories where problems increased the most were features, controls, and displays, along with infotainment.

Door handles, historically a non-issue, have become increasingly problematic, according to the study. They're particularly troublesome in electric vehicles, the study said.

"The basic touch point of door handles is now a percolating problem area as manufacturers attempt to redesign them," JD Power said. "Owners are having issues with high-tech approaches to this basic function."

Some drivers reported that wireless charging pads frequently overheated and sometimes wouldn't deliver a charge. They also experienced issues with safety systems like lane-keeping assistance and forward-collision warning.
