2025 Lexus Tx Problems

I am reporting a severe, systemic vehicle performance discrepancy on my 2025 Lexus TX 350h (2.4L Turbo Hybrid powertrain). The vehicle is officially labeled with an EPA rating of 23 MPG combined. However, under normal, conservative driving conditions, the vehicle routinely achieves only 17-17.7 MPG—a consistent 26%+ shortfall from the manufacturer's certified window sticker metrics. I have never gotten EPA higher than 17.7 since owning the new car. This has drastically limited the vehicle's safe total driving range to under 300 miles per tank. The shortfall persists despite cautious driving in Eco Mode and after passing the engine break-in period. This issue matches a widespread pattern reported by numerous other owners in consumer forums, pointing to a potential defect in the vehicle’s fuel management software or hybrid battery management logic. I request that NHTSA log this tracking data to investigate whether the manufacturer misrepresented the vehicle's real-world operational capabilities or fuel-system integration. I have a separate compliant #11762922 open for extreme safety concern related to visible gas vapors and overpowering health concerning gasoline smell at times which have occurred 5 times that I have recorded; unsure if this issue is related. Please investigate all the Lexus TX and Toyota Grand Highlander formal NHTSA complaints, Lexus Tickets, Technical Service Bulletin requests, and the previous Lexus Service repair for fuel leaking being a fire hazard - the fix was a fuel tank protector under Service Campaign #25LC05. My car had this protector installed; ironically there were no incidents of the gas smell & visible vapors until AFTER the service campaign and install of the fuel protector; coincidence or not. It seems highly probably that the following 4 issues are related on these cars: 1) fuel leaking/protector installed 2) gas mileage off 3) Visible gas vapors 4) strong gas smell. Please act before someone gets hurt. This is a family car w kids.

I am reporting a recurring potential fuel-system/EVAP safety issue with a 2025 Lexus TX 350 (same as Toyota Grand Highlander). On FIVE separate occasions (May, 6/27, July, 8/14, and 9/8/2026), I experienced an overwhelming raw gasoline odor associated with visible vapors coming from the fuel-filler/gas-cap area. Three incidents occurred after refueling; the two most recent occurred WITHOUT recent refueling and with less than half tank full. On 8/14, with temps in the 90s and approximately 135 miles to empty, I drove 30–40 miles, idled approximately 45 minutes, then drove another 10 miles. The overwhelming gasoline odor and visible vapors occurred again. On 9/8, at approximately 108°F and with 152 miles to empty, I drove 46 miles, idled 27 minutes, then drove another 10 miles. The overwhelming raw gasoline odor and visible vapors again came from the fuel-filler area. A strong gasoline odor was also present underneath/around the driver's-side rear wheel well, but not around the passenger-side rear wheel. This recurring release of gasoline vapors presents a potential fire and occupant/public safety concern because gasoline vapors are flammable. I have kept the vehicle outside after incidents rather than parking it in an enclosed garage near an ignition source. The vehicle is available for inspection. The vehicle was previously inspected by an authorized Lexus dealer for this same concern, and Lexus Brand Engagement opened a case and technical-assistance ticket. The dealer reported no fuel leak and deemed the vehicle safe to drive but did not reproduce the condition. The vehicle was driven only approximately 3 miles at the dealership under different conditions. The problem has since recurred multiple times. There have been NO warning lights or dashboard messages. The repeated visible vapors and overwhelming raw gasoline odor during normal operation raise concerns about a potentially unsafe fuel/EVAP system malfunction.

When starting from a stop, putting foot on the gas pedal the car won’t move. Hesitates for a longtime. It has happened numerous times since purchased new. The manufacturer stated that engineering is looking into it, with no definitive answers. No warning lights. It just won’t go, at times which is a safety concerning especially when crossing with oncoming traffic. Unresponsive.

The electronic throttle control, vehicle speed control, and powertrain/transmission control system failed. When I press the pedal to accelerate there was no power. However I did not lose power to the vehicle as I can see the vehicle was in Drive mode but was not moving forward. I was on a decline hill and the decline helped me go downwards before a truck could hit me. This total loss of acceleration has occurred exactly 2 times within a 4-week period. The vehicle is currently located at the Lexus dealership service center and is available for immediate inspection upon request. My wife and small children were in the vehicle when the accelerator pedal went completely dead while driving. The sudden drop in speed in active traffic almost caused us to be catastrophically rear-ended by an 18-wheeler semi-truck. After one minute of zero throttle, the vehicle violently jerked, locked us into a highly dangerous 5 MPH limp mode on the road, jerked a second time, and then suddenly resumed normal speed. My family's lives were put at extreme risk. No. The vehicle is currently at the authorized Lexus dealership for inspection, but the service department states they cannot find any diagnostic trouble codes (DTCs) and have not yet reproduced the intermittent failure on a test drive. The vehicle is currently under inspection by the authorized Lexus dealership service department. It has not yet been inspected by the manufacturer's regional corporate specialists, police, or insurance. No. There were absolutely no warning lamps, check engine lights, dashboard messages, or symptoms prior to either of the two failures. The loss of acceleration happened instantly without warning. The vehicle's computer system failed to store any error codes despite the severe mechanical jerking and the sudden 5 MPH speed restriction.

While my 2025 Lexus TX was parked in my residential garage, the vehicle suddenly locked itself with my [XXX] and [XXX] children and my phone inside. The doors had been unlocked prior to placing them in the vehicle. Without warning, the vehicle locked all doors and windows. The key fob failed to unlock the vehicle electronically or manually. My husband and I attempted for over 30 minutes to gain access while the children remained trapped inside before calling the dealership for technical help. They instead transferred us to Lexus roadside assistance. Lexus roadside assistance advised calling [XXX] to break the windows or otherwise enter the vehicle forcefully. However, before we could call, my husband figured out how to get a narrow opening to access the vehicle through the trunk to enter the interior and lower the windows in order to remove the children safely. The vehicle was taken to the dealership for inspection. This malfunction created a serious occupant entrapment safety hazard involving infants.

y 2025 Lexus TX500h experienced sudden and complete AC failure at fewer than 25,000 miles, 18 months after purchase. The selling dealer diagnosed a refrigerant leak from the AC condenser and denied warranty coverage citing road debris impact damage. No photographic documentation of a discrete impact event or specific leak point was provided to support the denial. This failure is consistent with a documented, systemic design vulnerability in the Lexus TX platform. The vehicle's wide-open front grille design allows road debris direct access to the AC condenser, which sits as the frontmost component in the cooling stack with no protective barrier. Multiple NHTSA complaints document identical failures on TX platform vehicles at extremely low mileages including 580 miles and 900 miles, with dealers uniformly denying warranty coverage. Operating without AC in Texas summer heat constitutes a safety hazard, particularly for child passengers. I am requesting NHTSA investigate this as a systemic design defect pattern across the TX platform. Attached photos include: (1) photos provided by the dealer as their evidence of "impact damage" — none of which document a specific leak point or impact deformation zone; and (2) photos taken by the owner of the condenser on the Westside Lexus loaner vehicle provided during this service visit, which show comparable fin condition and debris accumulation to the denied vehicle. The loaner vehicle photos demonstrate that this condenser condition is consistent with normal operation in this environment, not discrete impact damage.

On our 2025 Lexus TX350, less than 1 year old, and under normal driving conditions, our AC stopped working suddenly. Upon inspection at the dealership, they determined a rock or road debris came through the front grill and impacted the condenser, which caused a major refrigerant leak and ac to stop working. I believe this was due to a poor design of the lower half of the front grill, it’s wide open and offers little to no protection to ac and engine components. They should have a better honeycomb or similar grill to protect components. The refrigerant leak is an environmental and road safety issue, and living in hot climates like southern Nevada, when it’s 110 degrees outside, the heat inside the vehicle with no AC is a safety issue for children, adults, etc. The dealership did not cover repairs under warranty, and quoted $3,500 to repair either with cash or submit insurance claim.

The contact owns a 2025 Lexus TX350. The contact stated that while driving 50 MPH, the brake pedal was depressed and felt spongy, and the vehicle failed to respond as intended, causing the braking distance to be extended. The vehicle was taken to the dealer, where the contact was informed that the brakes were in good working condition; however, the failure persisted. The contact stated that while attempting to raise the folded passenger's side third row seat to the upright position, the back of the seat became stuck to an unknown part behind the seat, causing the seat to fail to respond as needed. The vehicle was taken to the dealer, where the contact was informed that the unknown part had been replaced, and the seat could be raised; however, the failure persisted. Additionally, the contact stated that fuel tank door had failed to open intermittently while pressing the release button on the steering wheel, forcing the contact to release the fuel tank door by engaging the emergency release manual button inside the trunk. The dealer was notified of the failure, and an appointment was scheduled for a diagnostic test. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 3,000.

While stopped in traffic with my foot firmly on the brake pedal, my vehicle began accelerating forward unexpectedly. The vehicle seemed "possessed". It was as if the gas pedal was fully on the ground while my foot was still on the brake, so the car was lurching and seemed to be fighting itself. The vehicle continued moving forward and would not stop despite sustained and hard brake pressure. I was rapidly closing distance on the vehicle in front of me and narrowly avoided a collision by inches. The vehicle only stopped after I shifted it into park and then I shut the car off. This was a terrifying and dangerous event. The vehicle accelerated against brake input and created an immediate collision risk. I reported this incident to my local Lexus dealership (Lexus of Fife, WA). However, the dealership minimized the event in their service documentation and did not accurately record my description of unintended acceleration while braking. At that time, I was informed that Lexus had issued a Technical Service Bulletin (TSB) related to this issue but has not issued a recall or broadly notified owners. If the manufacturer is aware of this defect and has not initiated a recall, I believe this poses a significant public safety risk. This issue presents a serious safety concern involving unintended acceleration despite brake application. I am concerned that other drivers could experience similar incidents, potentially resulting in injury or fatal accidents. I suspect that accidents have already resulted from this. I am requesting investigation into this defect. Owners should be notified and this should be recalled immediately.

We leased the Lexus at the end of May 2025. My husband I drove the car. It was nice. My husband and I are in our early [XXX] . Meaning we are very capable of driving. We both ride motorcycles, snowmobiles, dirt bikes,4 wheeling and we also own 1957 truck, 2024 corvette, and we even both drove our own corvettes at the spring mountain in Nevada. That being said this car is a nightmare. I don’t need a car to take over my driving, braking, and anything else. Whether it’s driving 75-80mph and you are on a major interstate and it decides that the sweeping curve is dangerous while I’m passing a semi or a string of cars! I don’t need it to slow down because it thinks too fast of a curve?!?!?. I took it to Brookfield Lexus for over a week I spoke with service told them what I dislike about the car. The one service tech said,”. You are not the only one that dislikes all of the safety features”! I asked him can you remove all of the safety features, “ he said not sure but we will do what we can”! When I picked up my car on Dec 20,2025 they showed me that only a couple of safety features can be shut off. The other ones have to be shut off manually everytime you start the car!!!!! I should not have to go into the computer and manually shut other features off because it’s back to flashing, beeping, and any other annoying features to put me in danger because it’s telling me you are going to have an accident!!!! It’s a distraction that is a problem. My daughter drove it home with our small trailer in a snowstorm last Sunday . My daughter was changing lanes and when she did your auto braking took control and she almost went in the ditch. With the trailer on the back it started to slide because it was overcompensating which put my daughter, the car, my trailer, and anyone else near her in danger. I spoke with Lexus Corporate and filed a complaint. They said there was nothing wrong with the car. There is a major problem with that car.

We have had 2 windshields crack on the Lexus TX350, with very low impact to the windshield by very small road debris. Both windshields require(d) replacement due to long migrating cracks. There are several issues with the windshields on the TX350 per online searches. The windshields are a laminated acrylic one that are prone to cracks requiring replacement. This is a common issue on the TX350. The windshields are on long back orders for a genuine Lexus part. We are having our second windshield replaced on XXX at the Lexus dealer. I am of the opinion that this issue should be looked into by NHTSA for a potential recall and improved manufacturing process for future original equipment and genuine Lexus replacement. Our TX350 will be available for inspection on XXX at Parker Lexus in Little Rock Arkansas. The approximate cost to replace the windshield is $1850.00. We are not claiming the windshield on our insurance for this replacement for fear of potentially being cancelled by our insurance company. Please research this issue at your earliest convenience and feel free to request more information from me if needed to help in the assessment of the problem. We look forward to hearing from you asap.

Basically, the instrument cluster lighting is very, very poor. Very difficult to read when driving, especially in a day break. You must turn off your daylight running lights to make it a little bit brighter. This is a problem.

My son was sitting in his rear passenger side seat belt and he shifted in his seat and became entrapped in his seatbelt which i could not release in any way so i had to pull over on the 15 freeway on a trip back from Las Vegas in the middle of a highway with no visible exits and cut him out of his seatbelt

We were driving down the highway and the vehicle started shaking. I immediately slowed down as I felt we had a flat. There was notification on the screen. I moved to the right onto the shoulder. Only after we were completely stopped did I see a low tire warning come on display. I slowly got out as the traffic was heavy. I could see the outer section of the tire came apart from both sides. As we were in a dangerous location someone called the police. Two police cars pulled behind us and provided us some safety. We agreed to swap out bad tire for spare as we were in a very dangerous location and needed to get vehicle moved before someone ran into all of us. We did look at the highway to ensure no objects were in the road. I didn’t see any while driving, but we wanted to verify to protect other drivers. There also weren’t any pot-holes in highway. We inspected tire after taking it off and there were no screws, nails, objects, or damage to the center tread/sides. The tire seemed to separate fairly cleanly on both sides. Tires were Continental Cross-contact 255/45 R22 107V LX20 (Eco plus) To repeat, no Warning Lights came on vehicle before tire came apart. I have sent message to my insurance company. No one has inspected tire and it is in my possession.
