What owners wrote

A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

ON jUNE 3, 2021 I experienced a drastic loss in power and all warning light illuminated on the dash , was able to get of the highway to a safe area and vehicle ceased to function . This happened after the fuel pump recall was performed at Ed Morse Toyota in Delray Beach around February. It had been functioning perfectly up until this massive failure. When tow truck operator arrived and tried to start, is caught fire and was severely damaged.

June 2021 Fire

Purchased rental program vehicle and immediately had vehicle serviced at the dealership. Received a phone call from service advisor that automotive technician had found a mechanical problem. It was stated that a hose had come loose/apart in the axle and fluid was leaking. Now, we had purchased vehicle day before and the following day dropped vehicle for service at dealership. As a consumer, I need a maintenance baseline.

The fuel pump needs replaced and has been recalled. The recall can cause an increased risk of a crash. We still haven't had this replaced in a timely manner and it's not safe for my small children.
