1996 Plymouth Neon Problems

What owners report

Complaints for this model year center overwhelmingly on engine oil leaks traced to the head gasket, often noted between roughly 30,000 and 100,000 miles and frequently recurring after repair; owners describe replacing the gasket multiple times. A second, smaller cluster involves engine wiring harness shorts that cause stalling or loss of power, and dashboard gauge failures. Brake, airbag and transmission complaints appear less often but are described as sudden rather than gradual.

   Engine oil leaks from the head gasket

   • 101 complaints (33%)
   • median 70,000 mi at 7.4 yrs old (8 state mileage, few)
   • 2 mention a crash, fire or injury
   • owner-quoted repair $800 (median of 9 quotes)
   • filed 1997–2004

   Owners describe oil leaking from the head gasket, sometimes found as spots on the driveway or a burning oil smell after the engine is shut off. Many say the repair was done once or repeatedly — several report two, three or four replacements — and that the leak returned shortly afterward or at intervals of roughly every 40,000 miles. Some note independent shops recognized the problem from the model alone, and that a redesigned gasket was later used; dealers are described as sometimes covering the repair under warranty and sometimes declining. Mileages in the sample range from about 26,000 to 116,000 miles, with many reports between 30,000 and 90,000 miles, and some owners reporting leaks reappearing within a few years of a previous repair.

   What to check: Check for oil residue around the head gasket area and underneath the engine, and look for drops on the ground after the car sits. Ask for records of any prior gasket replacement and which gasket type was installed.

   2 excerpts from owner complaints in NHTSA records

   “I have a 1996 NEON which I purchased used in august of 2001 with only 35,000 miles on it. About 3 months ago I took it in for my monthly oil change/lube and was told that my head gasket was cracked and that I would need to get it replaced. They told me it would be a $1200 repair. I began to call around and each place, when I mentioned the problem and the year/make/model of my car, told me that they could have guessed what the repair was that I needed just by me giving them the type of car I drive. …”

   NHTSA complaint #10008220, filed 2003-02, 91,000 miles

   “For the second time now my car has a leaky gasket (which has contributed to having to replace the radiator this time as well). I have heard endless stories of this happening to neons-when will a recall be enforced? This is obviously not an isolated problem when it is common knowledge among mechanics and owners of neons that this could happen.”

   Brakes

   Brake pedal goes to the floor or brakes drag

   • 17 complaints (6%)
   • median 45,000 mi at 9.1 yrs old (1 states mileage, few)
   • 3 mention a crash, fire or injury
   • filed 1996–2004

   Complaints describe the brake pedal sinking to the floor or feeling stuck, and in some cases calipers seizing so the brakes stay applied and wear into the rotors. Owners report squealing or noise from the brakes and say a dealer described the noise as normal for the vehicle; one owner reports a loss of braking that led to a collision. A recall for a master cylinder that can leak brake fluid covers related hardware. Mileages in the sample are mostly under 45,000 miles where stated, with reports filed from the mid-1990s through the early 2000s.

   Recall 96V075000

   What to check: Test the pedal for firmness and travel, check the fluid level and look for leaks around the master cylinder, and ask whether the master cylinder recall was completed.

   “Oil leaks, dashboard failure, noise in brakes, wind noise in passengers door. Have replaced valve cover gasket twice, replaced oil sendind unit,cam sensor was replaced now I have a big oil leak, car only has 45000 miles on it.”

   NHTSA complaint #10100675, filed 2004-11, 45,000 miles

   “Abs brakes; brake pedal goes to floor when applied. Owner spoke w/sport chrysler norristown, pa., and they told her brakes were self adjusting. Two days later she had an accident. Chrysler rep., wishes to inspect vehicle. Please describe details.”

   Electrical system

   Stalling and no-start traced to wiring harness short

   • 56 complaints (18%)
   • median 70,000 mi at 7.5 yrs old (5 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 1996–2021

   Complaints describe the engine cutting out while driving or failing to start, sometimes after a short drive, with some owners linking it to a short in the engine wiring harness near the exhaust. Several mention the check engine and oil lights coming on beforehand, and more than one owner says a dealer could not locate the cause or replaced other parts first, such as a fuel filter or coil pack, without solving it. Some owners reference the underhood wiring recall in connection with these symptoms. Reported across a wide mileage range, including a vehicle at 70,000 miles; several complaints do not state mileage.

   Recall 96V026000

   What to check: Ask whether the underhood wiring recall was performed for this vehicle and have the harness inspected for chafing or contact near the exhaust. Note any history of intermittent stalling or no-start conditions.

   “I took my car to horton's to have it put on the computer. They charged me $90.00 to put on a new fuel filter, when it is the wiring harness causing the problem. There is a recall for the wiring harness.please send me a recall for the parts on my car.”

   NHTSA complaint #729154, filed 2000-08

   “An electrical short in the wiring harness caused the vehicle to stall. The consumer received NHTSA recall 96v026000 concerning the wiring harness failure due to an electrical short, but chrysler told the consumer that this recall did not exist. The dealer could not locate the problem but stated that the wiring in the horn needed to be replaced. The electrical short and the engine misfiring caused the vehicle to lose power and sputter after a short drive.”

   Electrical system

   Dashboard gauges quit or swing erratically

   • 15 complaints (5%)
   • median 45,000 mi at 9.1 yrs old (3 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 1998–2021

   Owners report the instrument cluster going dead or the speedometer, tachometer, fuel and temperature gauges moving up and down or dropping to zero, sometimes while driving at highway speed and then coming back after a while. A few describe the gauges returning briefly when the dash is tapped or the car hits a bump, and one links a similar display problem to a break in the wiring. Reported from roughly 27,000 to 116,000 miles; several episodes happen at highway speeds and recur intermittently.

   1 related service bulletin

   What to check: Watch the gauges during a test drive, including at steady highway speed, and check whether they flicker or drop. Ask whether the cluster or its connector has been repaired.

   “The dash control's(speed)only works sometimes!the frontend feels like it is coming out from under the car, and the paint is peeling off the top and the sides. I am truely disappointed. Plus I have had it worked on for the headgasket.plus gas pedal sticks.”

   NHTSA complaint #736713, filed 2000-11

   “While driving, doesn't matter what type of surface all the gauges on my 1996 NEON failed. Sometimes if you tap the dashboard glass that covers the gauges they come back on or if you hit a bump in the road they come back on, but this isn't always the case. This has happened approximately 4-6 times over a six month period starting in may, 2004.”

   Air bags

   Airbags not deploying in a collision

   • 19 complaints (6%)
   • median 93,000 mi at 8.8 yrs old (2 state mileage, few)
   • 18 mention a crash, fire or injury
   • filed 1996–2004

   Several owners describe frontal or side impacts in which the airbags did not deploy, and one reports the bags deploying without a crash and catching fire. Mileage and circumstances vary, and in most cases the complaint is a description of what happened in the collision rather than a diagnosis. Reported at mileages from roughly 83,000 to 103,000 miles where stated; the complaints span model years of use rather than a single age window.

   What to check: Ask whether the airbag warning lamp works and stays off after the bulb-check period, and have any stored airbag fault codes read before purchase.

   “When turning into a parking lot dual airbags deployed inadvertently. As a result, when air bags deployed they caught on fire. Driver sustained burns to the chest.”

   NHTSA complaint #10091796, filed 2004-09, 103,000 miles

   “While traveling on the highway at a speed of 40mph, another vehicle pulled out in front of the vehicle, and the vehicle broadsided the vehicle that pulled out in front and the driver's side airbag didn't deploy.”

   NHTSA complaint #827432, filed 1998-09

Buying note. This model year draws repeated owner reports of head gasket oil leaks, often returning after repair, so service records and a careful leak inspection matter more than mileage alone. Also confirm whether the underhood wiring and brake master cylinder recalls were completed, and check the gauges and brakes during a test drive.

Summary written with AI from a sample of 60 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records. Where a problem shows a complaint count, every complaint for this model year was matched with fixed keyword rules (written with AI and tested against the sample), and the mileage, age and repair figures are calculated from those complaints; owners' figures are as stated, not verified. Other counts refer to the sample.
