Got a Dealer Quote? Get a Second Opinion First
When a Lexus shows a hybrid system warning, the dealer quote is often for a brand-new battery pack. That can be the right answer, but it isn’t always the only one. Many packs fail because a few modules have weakened while the rest are still healthy, and some warnings turn out not to be the battery at all.
A second opinion from us means testing the pack module by module and telling you plainly what we find:
If the pack is mostly healthy
We may recommend repairing or replacing only the weak modules. Module repair starts from $700 labor + parts.
If the pack is worn throughout
A full rebuild replaces every module with tested, matched reconditioned modules (not new). A Lexus CT200h rebuild is $1,600, and a Lexus RX400h/RX450h rebuild is $2,400.
If a new pack really is the best choice
We’ll say so. We can also quote new, remanufactured or tested-used replacements — call for a quote. If your Lexus may still be under the factory hybrid battery warranty, we’ll tell you before you spend anything.
Lexus Hybrid Battery Problems We See
- Lexus RX400h / RX450h — loss of power and hybrid warnings as packs age; see our Lexus RX400h/RX450h page.
- Lexus CT200h — falling fuel economy and the engine running more than usual; see our Lexus CT200h page.
- Lexus ES hybrids — we test these too; call for pricing on your model year.
- Battery pack codes such as P0A80, usually caused by a weak or unbalanced block.
- Cooling and temperature faults — a blocked battery fan or vent can trigger battery cooling and temperature codes.

How a Second-Opinion Visit Works
1. Send us the details
Call with the model, year, mileage, any codes and the dealer’s diagnosis or quote, if you have one.
2. We test on site
We scan the hybrid system and measure each module or block at your home or office in Southlake. Learn more about our diagnostics.
3. Compare the options
We walk you through the readings and give you a written price and warranty, so you can compare it side by side with the dealer quote.
4. Repair when you’re ready
If you go ahead, the $150 is credited toward the repair, and we road-test the car afterward.

Is Your Southlake Hybrid Still Under Factory Warranty?
Before paying anyone for a battery, including us, check whether the manufacturer should be paying instead. Late-model Toyota, Lexus and Hyundai hybrids may still be inside their factory battery coverage, and the terms vary more than most owners realize:
- Toyota: 2020 and newer hybrids are covered for 10 years/150,000 miles; 2019 and older for 8 years/100,000 miles.
- Lexus: coverage is set by Lexus, so check your warranty booklet or call a Lexus dealer with your VIN before approving a quote.
- Hyundai: on 2012–2019 Sonata Hybrids and similar models, the original owner has lifetime battery coverage; later owners are covered for 10 years/100,000 miles.
- The clock starts at the in-service date, the day the car was first sold, not the model year. Your dealer can look it up from the VIN.
Heat matters whether you’re covered or not. The National Weather Service’s DFW records put the average first 100°F day on July 1 and the last on August 27, and a pack that runs hot through that stretch ages faster. Keep the battery cooling fan clean so a cooling fault doesn’t turn into a bigger one.
If you’re past coverage, our written Battery Health Report gives you the voltage of every module before any price quote. It’s yours to keep, and it is a useful record whether you repair, replace or sell.
Hybrid Battery Replacement in Southlake, TX
Replacement is the right call when the whole pack is worn, when a lithium pack has a fault that can’t be serviced at the module level, or when you want the longest life from a vehicle you plan to keep. If testing shows only a few weak modules, a repair from $700 labor + parts is usually enough.
| Path | Typical fit |
|---|---|
| New pack | Late-model car you’ll keep for years |
| Remanufactured pack | Lower cost than new, with a pack tested before install |
| Tested-used pack | Older car where budget matters most |
| Full rebuild with tested, matched reconditioned modules (not new) | $1,600 for a Lexus CT200h, $2,400 for a Lexus RX400h/RX450h |
The price of a replacement depends on the vehicle, the pack type and the option you choose, so call for a quote. Full replacements often run $1,500–$4,000 at other shops, and more at a dealer. Our warranty runs 1 to 3 years depending on condition and mileage, and it is in writing before work begins. In Southlake the on-site diagnostic is $150 and 100% credited toward the repair.
