2026 Lexus Tx

The rear steering is malfunctioning, causing the car to pull. We had it realigned twice, and it's still doing the same thing. We are told by Lexus that the rear steering apparatus is broken and needs to be replaced, at a cost of $8700 to us. Although this occurred initially under normal driving conditions, they are claiming that it's not something that is covered under their warranty. Numerous cases of faulty rear steering have been reported for the Lexus TX and its equivalent, the Toyota Grand Highlander. In fact, some 2026 Lexus TX models have been recalled due to concerns about structural weakness in the rear steering apparatus. The failure of that rear-wheel steering can lead to vehicle instability and ultimately cause safety concerns for our family.

The air conditioning suddenly stopped working and it was 107 outside. I took the Lexus TX to Lexus service and they said a pebble went through the condenser. I had leased the car brand new in June 2026 and right now it's October 2026. I drive mostly on residential streets. I don't actually know what pebble hit the condenser or when it happened, the air conditioning just stopped working October 8. Lexus said it could have been a slow leak or leaked out quickly and there's not way to know. Because the hole is so small, I did not hear or feel anything when driving that would have indicated a strike. . I have photos from Lexus. They sent a picture and there were at least a dozen other noticeable strikes on the condenser. It was very uncomfortable driving. Our safety was put at risk because I live in a place where it's frequently over 100 degrees outside, I have an infant daughter and she cannot be exposed to such high heats for prolonged periods of time. I thought I had a car that would be reliable and safe for her and her health. This problem has been noted on many forums and Lexus owners have had many complaints about the same exact issue. It seems that there is a design flaw with the front grill that allows small debris and gravel/pebbles/etc. to easily strike the condenser and cause it to fail. Insurance is coming out to look at it because Lexus said it'll cost $2500 to repair it. If I had to pay $2500 every 4 months during the 3 year lease it would be close to $20,000 in repairs just for this design flaw, because it will keep happening over and over again just by driving the vehicle. There were no warnings or messages, and we didn't know what had happened until we took the car to Lexus and they told us.

Fuel indicator light does not turn on until 20 miles till empty. No indication on heads up display or info screen until 7 miles to empty and last for approximately 5 seconds, in blue, then goes away. This is particularly dangerous in areas that do not have many gas stations and in mountainous areas when fuel consumption is higher.

The contact owns a 2026 Lexus TX 350. After purchasing and taking ownership of the vehicle, the contact discovered that the vehicle was included in a recall prior to the purchase. The contact notified a local dealer and was referred to the manufacturer. The manufacturer was made aware of the issue and arranged for the vehicle to be inspected or serviced at the dealer. The dealer scheduled a service appointment; however, the dealer later declined to service the vehicle and informed the contact that the VIN was not associated with a recall. The dealer referred the contact to the manufacturer for loaner vehicle assistance. Additionally, the contact stated that the rear passenger-side tire frequently became flat. The contact also stated that there was an abnormal burning odor while coming to a stop, and that the TPMS warning light was illuminated. The vehicle was not diagnosed or repaired. The contact received notification of NHTSA Campaign Number: 26V437000 (Power Train); however, the part for the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure. The approximate failure mileage was 3,647.

On Saturday, August 22, 2026, while traveling on the highway with my two toddler-aged children in the vehicle, the temperature gauge entered the red zone and the vehicle automatically reduced power due to overheating. This forced me to navigate a power-reduced vehicle on a highway with minor children — a serious safety hazard. This incident occurred just five days after my vehicle was in the Sewell Lexus service department on August 17, 2026 for its 10,000-mile service and a warranty repair to the rear evaporator case (a known design defect). The proximity of this safety incident to that service visit raises significant concerns about whether the August 17 service contributed to or caused the overheating event.

We were traveling 80 miles west of Fargo ND on I94 when we heard a loud bang. It became clear immediately from the wind noise that the sunroof had broken. We did not hear or see that anything was dropped on it. Thankfully the shade was closed. We pulled off at the next possible stop to inspect and noted a large whole in the sunroof and that the glass bowed outward suggesting the explosion was an outward force rather than an item falling on the car. There were no warning lights etc. prior to this happening. This was a very frightening experience and had the shade not been closed our family including young son could have been hurt or even blinded from the falling glass. We called the dealer (we only had the car for 3 weeks) and they were able to get the car in right away to look at it but cannot guarantee the window is covered under warranty.

On Juky 7, 2026 @ 10:30pm a catastrophic safety failure occurred involving a 2026 Lexus TX 350. The vehicle experienced a complete electrical and software failure while an occupant (my mother) was inside. All electronic door release buttons failed simultaneously, completely locking the occupant inside the vehicle. The emergency manual double-pull override mechanism on the interior door handles failed to mechanically release or open any of the doors. Concurrently, the climate control system locked on high heat, causing the cabin temperature to rise rapidly. Due to the total entrapment and extreme heat, the occupant began losing consciousness, and her blood pressure spiked to a dangerous level of 188/100. Family members outside the vehicle were unable to open the doors or bypass the electronic locks from the exterior. Emergency services were called to the scene. The local Fire Department had to perform an emergency extraction to rescue the occupant from the vehicle. The occupant required immediate medical attention for severe heat stress and a hypertensive crisis.

During the manufacturing process, tires are mounted on the vehicle as matched sets to help reduce conditions such as pulling or drifting. If the wheels are replaced or refinished before vehicle delivery, it is important that the tires remain on the vehicle in the same location and in the same direction of rotation.
