2007 Camry Hybrid Battery Problem or Electrical Issues?


Asked by Jun 27, 2016 at 05:03 PM about the 2007 Toyota Camry Hybrid

Question type: Maintenance & Repair

I have a 2007 Toyota Camry Hybrid with approximately 134K miles.  The
"Check Hybrid System" comes on along with "Check VSC system".  The
VSC system always comes on a second or two after the check hybrid system
turns on.  Lately, I have been getting anywhere between 32 and 34 MPG
with my car.  I drive approximately 1000 miles a week.  The light usually
turns on immediately after I start the car and while I'm backing up.  They
came on several times before and I usually go to the 12 volt battery in the
trunk and disconnect it to reset the whole system.  Then everything runs
smooth again for about a week.  The hybrid battery charges up to about 90%
or level 7.  For some reason, I never see it up to level 8 which is the highest.  
Do you think the hybrid battery needs replacement or the car has an
electrical problem.?  I live in FL and it's really hot nowadays.

Sounds like you need to have the computers on this vehicle scanned with the appropriate SCAN TOOL. I suspect a wheel speed sensor failure. There are some Auto Parts Stores which provide scan services for free. Is there an "AUTO Zone" in your area?

Thank you Tony for your insight. Yes I do have Advanced Auto Parts and AutoZone nearby to have it scanned. Also, I had it read at Toyota Dealership a while back and they told me I needed to replace my whole Hybrid Battery pack. I can never trust these guys which is why I am seeking others opinion on this.

Understand your concern about Toyota .....unfortunately the diagnosis of your Battery Pack requires the detailed data stream a Factory Scan Tool provides. Did Toyota write on the repair order the ID of the codes they found which led them to their diagnosis? They should have. The ID of the codes being set when that warning light comes on is key. Make some phone calls to various INDEPENDANT garages. Some...do invest in a Factory Scan Tool. They usually charge about $100.00 for a Scan diagnosis vs...What was the estimate for a Battery Pack from Toyota?


I actually never thought to look for a code that led Toyota to this conclusion. However, I pulled my receipt and there is no code shown. See attached photo. The battery pack is estimated at $4,920.00 before labor.


IMO...I would want a second opinion including the rational...eg..trouble codes stored in the computer....and the labor charge. Toyota used to claim these batteries would last 100,000 miles or 10 years. Since you are over this mileage....It might be interesting to do some shopping around for a "good used" battery pack. There should be some wrecked hybrids in the junk yards. Keep in mind there is a huge safety issue associated with this battery replacement. High Voltage stored in this battery could kill.

Recognizing this is 8-months old, hoping to help someone else maybe: Check the 12v battery in the trunk. If you don't have the tools yourself, drive to Autozone or Pepboys etc and ask them to test it (many of them will come out to the car). Apparently 2007 era hybrids can throw this code when the "normal" battery (not the big battery pack) goes bad. Try that first!


Gilbert....did you ever resolve this issue with your vehicle?


No, I'm still driving with the "Check Hybrid System" light on and I can see the gas mileage is progressively diminishing after I log my fuel assumption. I had the car read by an independent hybrid battery replacement mechanic and by Goodyear Auto, and they both conclude it's the hybrid battery. It has been over a year since the light came on, but the car is still driveable. I don't plan on taking any more actions unless you have a suggestion that involves not replacing the battery and save me my wallet. Thank You for responding. I truly appreciate it.


I would shop around for an aftermarket battery pack. I see battery packs for $1,000 to $2,000. Installation would be extra and all batteries are not the same so check them out first.


I have shopped around and found refurbish battery pack anywhere between $1,100 and 2,500 depending on level of warranty selected. I'm wondering if I can drive the car until the hybrid pack in my car completely dies. Then I'll replace it. Any reason not to do that other than being stranded at the worst time possible? I guess that's the risk I'm willing to take. Please advise.
