Flower Mound stretches north from Grapevine Lake through neighborhoods along FM 2499 and FM 1171 (Cross Timbers Road). Many residents put serious miles on their cars commuting to jobs across the Metroplex, and a hybrid is a popular way to keep fuel costs down on those long daily drives.

Buying a Used Hybrid? Test the Battery First
A used Prius, Camry Hybrid or Lexus can be a great value — or an expensive surprise. The hybrid battery is the most costly part on the car, and a pack that is starting to fail can look fine on a short test drive. A dashboard with no warning lights does not tell you how evenly the modules are matched.
What we check
We scan the hybrid system for stored and pending codes, measure each block of the pack under load, look at temperature readings and inspect the cooling fan and intake. You get the numbers and a plain-English summary of what they mean.
Check the factory warranty
Toyota hybrid batteries on 2020 and newer models carry a 10-year/150,000-mile warranty; 2019 and older are 8 years/100,000 miles. On 2012–2019 Hyundai Sonata Hybrids, the original owner has lifetime coverage, while later owners get 10 years/100,000 miles. Knowing where a car stands helps you negotiate.
Use the results to decide
If the pack is weak, you can walk away, negotiate the price, or plan a repair. The diagnostic is $150 and is credited toward any repair we do on that car.
Long commutes put a lot of charge cycles on a pack each year, so a high-mileage commuter car is exactly the kind of vehicle that deserves a test before you sign.
Battery Problems We See on Commuter Hybrids
- P0A80 “replace hybrid battery pack” on Toyota and Lexus models
- Voltage sensing faults like P0AFA and related codes
- Isolation faults such as P0AA6 that need careful diagnosis
- Gas mileage slowly dropping on the same daily route
We work on the Toyota Prius Gen 3, Lexus CT200h and many other Toyota, Lexus, Hyundai, Kia, Honda, Ford, Nissan and Chevrolet hybrids — see all vehicles we service or our hybrid battery codes guide.
Four Steps From Call to Answer
1. Tell us about the car
Share the model, year, mileage and whether you own it or are thinking of buying it.
2. Meet at the car
We come to your home, workplace or the seller’s location if they agree. Read more about our diagnostics.
3. Get the full picture
We go over the block readings and codes and explain what is healthy, what is weak and what it would cost to fix.
4. Repair if you choose
If you go ahead, we repair the pack, clear codes and road-test the car with live battery data.
Repair and Rebuild Prices
Module repair starts from $700 labor + parts. Full rebuilds start at $1,300 depending on the model — for example $1,400 for a Prius Gen3 and $1,600 for a Lexus CT200h. Every model is listed on our hybrid battery cost page. For a car that has been sitting on a lot and won’t start, an external hybrid battery charge starts from $300.

Family Hybrid SUVs in Flower Mound: Lexus RX and Toyota Hybrids
In Flower Mound, FM 2499 (Long Prairie Road) runs north–south toward State Highway 121, Grapevine Lake forms much of the southern boundary, and US 377 runs along the town’s western edge. DFW Airport is about four miles south of town. If your household drives a hybrid SUV, such as a Lexus RX400h or RX450h or a Toyota hybrid, it probably handles school runs, weekend sports and airport trips.
Those SUVs are heavier than a sedan and often carry a full load, so the battery works hard pulling away from every light on FM 2499. Older hybrid SUVs such as the RX400h are long past their factory hybrid battery coverage, and on Toyota hybrids from 2019 and earlier that coverage is 8 years/100,000 miles. When the pack weakens, owners often notice reduced power with the family on board before they see a warning light.
- Slower or uneven acceleration when the SUV is loaded
- The engine running more often around town
- Fuel economy falling on the same school and work routes
- A hybrid warning that appears on a hot afternoon or after a long drive
Our Lexus RX400h/RX450h page covers these SUVs in detail. A full rebuild for an RX400h or RX450h is $2,400, tax and mobile service included. Jay, the specialist who does the work, comes to your driveway with the tools to test the pack on site.
Hybrid Battery Replacement in Flower Mound, TX
Replacement is the right call when the pack is worn throughout, not just in a few places: many modules testing weak at the same time, a damaged or badly corroded case, or a pack that has already been repaired before and is failing again. If only some modules are weak, a repair is usually the better value, and we will say so.
| Option | What it is | Often a good fit when |
|---|---|---|
| New pack | A brand-new replacement battery | You plan to keep the car for many years |
| Remanufactured pack | A rebuilt pack prepared before installation | You want a full replacement at a lower cost than new |
| Tested-used pack | A used pack that has been tested first | The car is older and budget matters most |
| Full rebuild (alternative) | Your pack with all modules replaced by tested, matched reconditioned modules (not new) | The case and electronics are sound and you want a lower price |
What changes the price: the vehicle, the type of pack it uses, and which option you choose. Replacement packs are priced by quote, so call for a quote; rebuild prices by model are listed on our hybrid battery cost page, and options are explained on our hybrid battery replacement page. The warranty for your job is given in writing before work begins, from 1 to 3 years depending on condition and mileage. In Flower Mound, the on-site diagnostic is $150 and 100% credited toward the repair, and you receive a written Battery Health Report with the voltage of every module before any price quote. Call (469) 773-9407 or request service online.
