X7 vs TX

The BMW X7 has several documented problems, with the most common being rear air suspension leaks, Valvetronic actuator faults, cooling system leaks, premature front brake rotor pulsation, and battery drain. These issues affect various model years from 2019 to 2023, leading to symptoms like suspension collapse, engine power loss, coolant loss, brake vibration, and dead batteries. Ignoring these problems can lead to more severe damage, such as compressor burnout, engine overheating, or starting failure.

Yes, the BMW X7 (especially 2019-2021 models) commonly experiences rear air suspension leaks, leading to the vehicle sitting low, particularly on one rear corner. This triggers a 'Chassis malfunction' or 'Level control malfunction' warning, and if ignored, the air compressor may burn out. Replacement of a rear air spring typically costs between $1,200 and $3,200 depending on the service provider.

The Valvetronic actuator and eccentric shaft fault is common in 2019-2021 BMW X7 xDrive40i models with the B58 engine. Symptoms include check-engine light, rough idle, loss of power, and limp mode. The repair typically costs between $1,200 and $3,500, with independent shops at the lower end and dealerships at the higher end.

Cooling system issues, particularly with plastic components, are common in 2019-2021 X7s with the B58 engine. Symptoms include frequent 'low coolant' messages, coolant puddles, and overheating if ignored. Repairing the expansion tank and hoses costs $400-$900, while replacing the electric water pump can cost $900-$1,700.

Premature front brake rotor pulsation, causing vibration in the pedal and steering wheel, affects many 2019-2023 X7s, especially V8 models. The issue is likely due to the vehicle's weight and brake pad bedding. Replacing front rotors and pads costs $850-$2,500, depending on the shop (independent versus dealer).

Battery drain in 2019-2021 BMW X7s with iDrive 7 often results from modules not entering sleep mode, causing the battery to die after a few days of sitting. This can lead to no-start situations and repeated jump starts, harming the AGM battery. Diagnosis costs $200-$400, an AGM battery replacement is $500-$800, and a module software update can cost $300-$600.

Yes. The 2024 Lexus TX, including all powertrains, is covered by recall 24V461000 because the curtain airbag may fail to deploy in a side impact or rollover, increasing injury risk. The remedy is a dealer inspection and replacement done free of charge under federal recall law, so confirm the recall has been completed before buying.

Yes. The 2026 Lexus TX is covered by campaign 26V437000, in which the rear axle carrier may have been manufactured with insufficient material strength and could break. A broken rear axle carrier can cause loss of vehicle control; because remedy notices were still being mailed as of August 2026, ask the seller or dealer specifically whether campaign 26V437000 has been performed.

Yes. The 2024 and 2025 Lexus TX models have software recalls for an instrument-panel display bug, a rearview-camera freeze, and a separate rearview-image bug. These defects can reduce driver visibility or awareness when reversing, and the no-charge remedy is a dealer-installed software update; verify the updates are already installed.

Yes. The 2025 Lexus TX is affected by campaign 26V179000, which addresses an incorrect load-capacity label. The inaccurate label could lead an owner to overload the vehicle unknowingly, and the remedy is a free corrected label; this campaign is non-structural.
