Electrical system

“We recently had a full diagnostic check done on our vehicle (199 point at Parkway Automotive in Little Rock, Arkansas) that listed some components in need of repair. The only part involving the electrical system needing repair was our battery which was testing as no longer holding enough charge. We took the vehicle to Sam's Club in North Little Rock, AR within the last 2-3 weeks and had the battery replaced with a new Duracell with 3 year warranty. We drove away with no issues with the vehicle and used it for local driving without issues for those 2-3 weeks. The morning of Thursday, December 29, 2022 we started the car to drive to our church about 2 miles away with our four young children (1, 5, 8, 10). In the short drive, dash lights were flickering and the nav/audio screen system was turning off and restarting. Upon arrival at the church, as we were parking the car, gray smoke began to come from the hood quickly.

Power train

17 reports1 related recall
“Massive Oil Leak and Loss of Oil Pressure: Oil line burst while driving on the HWY coming back home from a work. Loss nearly all of the oil, but there were no warning lights. Pulled over into gas station. Checked dip stick, completely dry! Catastrophic oil leak without warning. Could have been stalled on the HWY and caused major ACCIDENT. Tried to refill oil but it all leaked out as soon as I started engine. Research around the web and find out that this is a known issue to Toyota for using rubber VVTI oil line - Part # 15772-31030 Now this part is made all metal!”
