ELECTRONIC STABILITY CONTROL (ESC):CONTROL MODULE:SOFTWARE

Summary

Toyota Engineering & Manufacturing (Toyota) is recalling certain 2022 Lexus LX 600, Lexus NX 350h, Lexus NX 450h+, Toytoa RAV4 Hybrid, 2021-2022 Lexus LS 500h, Toyota Mirai, RAV4 PRIME, Sienna, Venza, and 2020-2022 Toyota Highlander Hybrid vehicles. The Skid Control ECU software may not turn on the Vehicle Stability Control (VSC) system when the vehicle is restarted after the driver has disabled the VSC system. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 126, "Electronic Stability Control Systems."

Consequence

Driving with a deactivated stability control system increases the risk of a crash.

Remedy

Dealers will update the Skid Control ECU software, free of charge. Owner notification letters were mailed May 27, 2022. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is 22TA03. Lexus' number for this recall is 22LA01.

STRUCTURE

The driver’s side door mirror shakes when going down the road. The image in the mirror becomes shaky. The passenger side is fine, this is only on the driver side. I have brought this into the dealer, but they said it is normal. In 30+ years of driving cars, I have never had a car mirror do this.

AIR BAGS

The contact owns a 2021 Toyota Sienna. The contact received notification of NHTSA Campaign Number: 23V865000 (AIR BAGS). However, the part to do the recall repair was not yet available. The contact stated that the air bag sensor turned off and failed to function as intended. The local dealer was not contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue but offered no assistance. The manufacturer advised the contact to stop driving the vehicle. The failure mileage was approximately 30,000.

Brakes🔶 Medium
SERVICE BRAKES

When braking to a stop at low speed (stopping at stop sign or at light), then car accelerates forward even though my foot is on the brake attempting to slow the car down. This unintended acceleration is dangerous and can cause an accident.

It has been 22 months since the recall (NHTSA Number 23V865) and over a year since the expected remedy date. What is the status update? What is causing the delay?

Body/Interior⚠️ High
SEATS

2nd row passenger seat recline does not work. My seat is very reclined now causing the 2nd row passenger to not be in the optimal position for SRS airbag performance that may result in possible death due to head impact during a side collision. Toyota likely has enough data to issue a TSB to resolve this issue preventing serious injury or death to one of my children.

Engine/Powertrain🔶 Medium
POWER TRAIN

While driving my 2021 Toyota Sienna Hybrid, the vehicle suddenly displayed a low oil pressure warning, immediately lost power, and entered limp mode. I was able to pull over safely, but the engine then suffered a catastrophic failure — a connecting rod blew through the engine block, leaving large metal fragments inside the engine compartment. The vehicle is completely inoperable. Prior to this event the van sometimes idled rough and shook slightly on startup when transitioning from battery to gasoline engine after sitting, but it drove normally otherwise. I have performed regular oil changes and routine maintenance according to Toyota’s schedule. Safety Concern: This failure happened suddenly and without warning. If it had occurred at highway speeds, it could have caused a serious crash due to loss of power or debris from the engine. This presents a significant safety hazard for drivers and passengers. Toyota has issued TSB T-SB-0104-21 for the 2021 Sienna Hybrid’s A25A-FXS engine addressing “MIL ON with Low Oil Pressure” conditions and DTCs P05202A/P052477 with milky or discolored oil. This suggests Toyota is aware of oil pressure and lubrication issues on this engine family. My catastrophic failure appears consistent with a loss of oil pressure or lubrication. I am filing this complaint to alert NHTSA of a possible defect or safety issue affecting 2021 Toyota Sienna Hybrid engines that can result in sudden catastrophic engine failure.

Visibility🔵 Low
VISIBILITY

2021 Sienna Hybrid Platinum AWD ~65K miles. Safety Issue: Fogging of windows increased, as AC was not working properly. Believe rear AC lines had galvanic corrosion from differing metals, steel bracket with aluminum line-sets causes corrosion hole in refrigerant line set, and leak causing loss of all Freon. No warning lights or messages, AC just stop blowing cold. Vehicle is driven in Michigan on winter roads with road salt, but stored in garage and only 4 years old. $1742 fix to replace line-sets, which can corrode again without proper design fix. Problem confirmed by dealer, and seen in other similar year Sienna's.

I purchased a 2021 Toyota Sienna (VIN: [XXX] ) from an authorized Toyota dealer in June 2024. At the time of sale, I was assured that the open safety recall (23TA15) would be repaired soon. More than a year later, no remedy has been offered, leaving me and my family driving an unsafe vehicle. Toyota’s own phase schedule indicates repairs should already be available in Washington State, yet I have been repeatedly told no repair exists. This has caused serious safety concerns, financial hardship, and loss of trust. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
