The 2007 Hyundai Sonata GLS presents a few mechanical challenges as it gets older. Engine failures after the 100,000-mile mark, bad rear brake design, and an investigation for poor throttle control may require a second look. However, it still garners positive reviews from owners.
Key Points
- The 2007 Hyundai Sonata GLS is the entry-level trim for the midsize sedan known for its spaciousness, good fuel economy, and low maintenance costs.
- Recalls issued by the National Highway Traffic Safety Administration included replacing bad airbag sensors and a rear stop light switch.
- Drivers experience problems with sticking rear brakes, fuse boxes, and relatively early engine failure.
- An open investigation at the NHTSA is looking into accidents caused by sudden uncontrolled acceleration.
- The most common problems are not indicative of a bad model or year. Many owners still rave about their 2007 Hyundai Sonata GLS.
Seven Early Recalls Issued for the 2007 Hyundai Sonata GLS Address Problems With Airbags and Corroding Suspension Parts
The GLS is the base trim for the midsize family sedan. The popular ride features plenty of room to seat five and offers a 2.4L or 3.3L engine.
The vehicle gathered seven recalls issued by the National Highway Traffic Safety Administration over its 15-year lifespan.
One major 2008 recall required inspecting the front passenger seat airbag sensor and replacing it as required. A bad stop light switch was recalled in 2009 and replaced on every sedan.
The most recent recall, launched in 2013, required the replacement of corroding rear cross members to prevent suspension failure while on the move.
Since the last recall launched nearly 10 years ago, any vehicle that you might be considering should have had any of these problems fixed by now.
A 2007 Hyundai Sonata GLS With More than 100,000 Miles May Suffer Engine Failure
Total engine failure is the most common issue reported by drivers at Car Complaints for the 2007 Hyundai Sonata GLS. These failures generally occur after the 100,000 and before the 140,000-mile mark and are associated with both the 2.4L and 3.3L offered on the GLS trim.
While high mileage may be the root cause, it is also possible that a rough idle attributed to a stuck exhaust gas recirculation valve could damage the pistons and combustion chamber.
My Car Specs lists the bad exhaust gas recirculation valve as one of its six common problems related to the 2007 Hyundai Sonata with a 2.4L engine.
Any engine light, hesitation at the lights, or unusual engine noise should be fully investigated by a qualified mechanic.
Owners Complain of Sticking Brakes and Airbag Warning Lights Randomly Activating
The 2007 Hyundai Sonata GLS gathered a relatively high 676 complaints with the NHTSA. However, the majority appear prior to 2015 and focus heavily on problems with the airbags and brakes.
Owners experienced airbag warning lights that would not shut off due to a faulty sensor in the passenger seat. The airbag complaints dropped significantly after the completion of the 2008 recall that replaced the passenger seat sensor.
Squealing, vibrating, and sticking rear brakes are often reported on the 2007 Hyundai Sonata. Drivers experienced early failure of rotors, calipers, and brake pads.
The most-reported problem is with the brake lights, which stick in the on or off position. The source of the problem seems to be a bad fuse box that may also cause havoc with the air conditioning, cabin lights, and radio.
Owners in the Hyundai Forums report saving up to $500 on the fuse box alone when they opt for buying from a parts store instead of the dealership.
An Open Investigation for Unpredictable Acceleration Puts the Spotlight on Safety Concerns
Four safety investigations are associated with the 2007 Hyundai Sonata GLS, but only one remains active and is focused on defects in the electronic throttle control system.
The earlier three investigations all resulted in recalls and a warranty extension for its electronic seatbelt pre-tensioner system.
The open investigation at the NHTSA focuses on unpredictable acceleration. The initial petition filed in 2021 cites sudden runaway throttle conditions that are associated with eight deaths.
Multiple complaints indicate that the driver has no warning of sudden acceleration and braking may not slow the vehicle.
2007 Hyundai Sonata GLS is Generally Regarded as a Reliable Older Car if Properly Inspected Before Buying
While all these problems may make it sound like the 2007 Hyundai Sonata GLS is a ride to avoid, its host of loyal owners disagree. Many drivers at Vehicle History continue to rave about its fuel economy, dependability, and affordability.
“Good size for a family car. Front and back seats have a lot of room. Good on gas. Big trunk, does not wear on tires. Love it,” says one owner.
So, if you are looking for an older, affordable sedan, take the 2007 Hyundai Sonata GLS to your trusted mechanic and have them look for its most common problems. If it has a clean bill of health, it is likely a good investment.
