2007 Toyota Camry engine problems

Engine burning oil at rates well above Toyota's claimed normal specification. Owners report consuming 1–3+ quarts between 1,000–5,000 miles, requiring frequent top-offs. No external leaks detected. Attributed to defective pistons and piston rings (2AZ-FE engine family). This is a chronic, progressive issue that can lead to low oil warnings, engine knocking, and ultimately catastrophic failure.

When: Manifests early in vehicle ownership; worsens with mileage. Many reports indicate problems appearing by 50,000–80,000 miles.

Symptoms owners cite: Oil light coming on well before scheduled oil changes; Dipstick reading nearly dry despite recent top-offs; Engine knocking or ticking sounds under load; Blue/white smoke from exhaust on startup or acceleration; Oil smell through A/C or engine bay; Engine seizing or stalling due to oil starvation

Codes mentioned: P0011 (camshaft timing), Check engine light (various codes related to emissions and misfires)

Repairs/costs cited: Oil consumption tests often show failure or borderline results, but dealerships frequently claim "passing" results even when owners report ongoing consumption. Toyota issued TSB T-SB-0094-11 and a warranty enhancement program (later expired or not communicated to all owners). Repairs cited include engine overhaul ($4,100–$6,400), short-block replacement ($5,500–$6,400), and full engine replacement ($12,000). Some owners report Toyota initially replaced pistons and rings but the problem recurred. Independent shops charged $3,800–$5,000+ for rebuilds. Many owners denied warranty coverage or reimbursement after expiration dates.

Recalls/TSBs owners mention: Toyota issued TSB T-SB-0094-11 (oil consumption) and T-SB-0158-14 (secondary oil consumption follow-up). Extended warranty coverage offered under a "warranty enhancement program" for oil consumption testing, but details not communicated clearly to all owners via mail. Some owners report being told the warranty expired or mileage limit (150,000 miles, 10 years) exceeded. Campaign LSC 90-K Phase Two addressed VVTi oil line rupture but expired March 31, 2013 for many owners. Toyota repeatedly claimed oil consumption rates of up to 1 quart per 1,000–1,200 miles as "normal," citing the owner's manual.

Rubber-and-metal oil line feeding variable valve timing (VVTi) system ruptures or severely leaks, dumping engine oil rapidly with no warning lights. No check engine or oil pressure warning illuminates. Oil spills onto hot exhaust system and undercarriage, creating fire hazard and causing severe engine damage (spun bearings, locked-up engines). Owners describe finding oil puddles beneath the car or oil spray covering the engine bay.

When: Can occur anywhere from 19,000 to 100,000+ miles. Multiple reports in the 50,000–90,000-mile range.

Symptoms owners cite: Oil smell through A/C or strong odor in engine bay; Puddle of oil under vehicle; no visible source; Oil spatter covering passenger side of engine or entire engine bay; Loss of 1–4+ quarts of oil in very short period (minutes to hours); No warning lights or check engine light illumination; Engine noise changes or engine stalls (when severe); Slipping on wet road due to oil on driveway/street

Repairs/costs cited: Rubber hose section requires replacement; Toyota eventually changed design to all-metal oil line (fix instituted April 2008 in North American plants). Cost typically $200–$500 for hose replacement at dealership. However, if engine damage occurs (spun bearings, crank/rod damage), engine replacement ($5,000–$12,000) may be needed. One owner reported 5-week national backorder for the hose part.

Recalls/TSBs owners mention: Toyota issued LSC 90-K Phase Two campaign to replace the defective hose with an all-metal assembly, but campaign expired March 31, 2013 for most owners. Many owners were unaware of the campaign or received no notification. After expiration, Toyota refused coverage, offering only limited reimbursement for future parts/service or small goodwill credits ($1,000–$2,000). One account reports Toyota aware of approximately 1,100 vehicles with this issue nationwide.

Engine fails to respond promptly when accelerator is pressed, causing 1–2 second (or longer) delay before acceleration begins. Behavior is inconsistent and repeatable. Most pronounced when accelerating from a rolling start or at higher speeds; less noticeable from a dead stop. Termed a "drive-by-wire" or throttle response issue by some owners. Creates safety hazard when merging onto highways or navigating intersections.

When: Present from early ownership or develops within first year. Reported in early 2005–2010 timeframe for 2007 models.

Symptoms owners cite: 1–2 second lag before engine revs or vehicle accelerates when pressing gas pedal; Unpredictable and delayed throttle response, especially when rolling or changing lanes; Engine RPM increase takes excessive time; transmission shift into lower gear delayed; Safety risk: unable to accelerate quickly to avoid traffic or clear intersections; Problem not present from complete stop (dead stop acceleration works normally); Behavior described as 'designed in' by Toyota service advisors

Repairs/costs cited: No successful repair documented in complaints. Multiple dealership visits and Toyota corporate calls resulted in "operating as designed" responses. One owner reports transmission replacement and computer reboot attempted with no resolution.

Recalls/TSBs owners mention: Toyota consistently told owners the vehicle is "operating normally" and "as designed." No TSB or service bulletins for this issue appear in the complaint narratives. Multiple owners report dealer service managers stating "nothing can be done" or dismissing the problem. One owner notes this is a known issue discussed extensively on Edmunds forums but has received no official acknowledgment or fix from Toyota.

Check engine light triggered by faulty camshaft timing gear (part of VVTi system). If not addressed, internal engine damage including bearing failure, connecting rod seizure, and piston damage can occur. One case involved a ticking noise progressing to loud knocking, then complete engine failure requiring replacement.

When: Can occur between 50,000–90,000 miles. In one case, occurred at 64,756 miles.

Symptoms owners cite: Check engine light illumination; Ticking or knocking noise under hood that worsens over time; Noise not always apparent during rainy test drives; Knocking sound on acceleration; progressively louder; Engine seizes or loses power; will not start; Loud banging/clanging during restart attempts

Codes mentioned: Check engine light (camshaft timing related)

Repairs/costs cited: Camshaft timing gear replacement initially recommended. However, if internal damage has occurred, short-block or complete engine replacement required ($5,500–$12,000). One owner received estimates for used engines, none warranted beyond one year. Dealer offered discounts on replacement engine costs.

Recalls/TSBs owners mention: Service advisors initially recommend delaying part replacement until light comes back on. No proactive notification to owners. When internal damage occurs, Toyota offers no warranty assistance if vehicle is out of the original powertrain warranty (typically 5 years / 60,000 miles).

Vehicle accelerated without driver input on the accelerator pedal. One documented case involved an undercover police vehicle that completed Toyota's acceleration recall service (SSC90L) just 7 days prior, then experienced sudden acceleration at highway speed reaching over 60 mph. Acceleration event corrected itself; no crash occurred. Raises concern about effectiveness of recall service.

When: Occurred March 10, 2010, just 8 days after completion of recall service on March 2, 2010.

Symptoms owners cite: Sudden, unexplained increase in engine speed and vehicle velocity; Accelerator pedal not depressed by driver; Vehicle speed reached over 60 mph; Acceleration event self-corrected after ~0.1 mile

Repairs/costs cited: Vehicle was secured after incident and not examined. No repair information available.

Recalls/TSBs owners mention: Recall service SSC90L was completed on the vehicle 8 days prior. Short time between service completion and incident suggests possible defect in recall repair procedure or incomplete fix.

ABS actuator assembly failure causing clicking noises under hood and crunching sounds when braking. Check engine light eventually illuminates. Problem develops gradually; warning lights may not appear for weeks after initial symptoms.

When: Reported in 2007 Camry hybrid models around 70,000 miles.

Symptoms owners cite: Clicking noise under hood near engine and brakes; Crunching sound when slowing down or stopping; Clicking noise continues even after engine is turned off; Check engine and ABS warning lights on dashboard (appear later)

Codes mentioned: ABS fault codes

Repairs/costs cited: ABS actuator replacement required at cost exceeding $2,000. One owner noted no recalls issued despite multiple complaints.

Recalls/TSBs owners mention: Toyota told owner there were not "a sufficient number of complaints" to warrant a recall. Owner filed complaint and received a case number for potential reimbursement only if the issue later became a recall. No manufacturer action taken.

Transmission failure in a used 2007 Camry purchased with full maintenance records. Owner states transmission fluid was never serviced because it was not on Toyota's maintenance schedule, but some independent shops claim transmission fluid should be changed periodically. Multiple independent shops cited defects in bolts and internal components as common issues in 2007 Camry transmissions.

When: Occurred approximately 3 years after purchase (roughly 80,000+ miles).

Symptoms owners cite: Transmission will not shift or engage; vehicle undrivable; No prior warning signs or check engine light

Repairs/costs cited: Multiple transmission shops quoted $4,800 for repair. One independent shop (Cottman's Transmission, Waldorf MD) performed rebuild for unspecified lower price and offered 3-year warranty. Owner states transmission was rebuilt but does not drive the same afterward.

Recalls/TSBs owners mention: Toyota dealer initially offered only 10% discount ($480 off $4,800 quote). Later offered 50% discount ($2,400) but refused to cover full cost. No warranty coverage applied. Owner stated shop owners indicated defects in bolts and internal components are "common" in 2007 Camry transmissions.
