2021 Jeep Grand Cherokee Suspension Problems

BE ASVISED, THIS REPORT MAY BE INTERCEPTED, DELETED, HIDDEN, OR MODIFIED UPON RECEIVING. NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION Vehicle Safety Complaint Complainant: [XXX] [XXX] [XXX] Vehicle: 2021 Jeep Grand Cherokee ------------------------------------- SAFETY DEFECT COMPLAINT – POST-REPAIR VEHICLE CONDITION I am reporting a serious safety concern involving my vehicle following collision repairs performed by Gerber Collision & Glass under a claim handled by State Farm Insurance. After the repair, the vehicle began exhibiting multiple safety-related issues, including: - Steering instability and shaking - Engine performance issues and abnormal noise - HVAC malfunction - Persistent chemical and/or coolant odors - Physical symptoms while driving, including dizziness, lightheadedness, and shortness of breath I returned to the repair facility with photographic evidence showing parts with visible wear and damage that appear inconsistent with proper replacement. Despite this, no diagnostic evaluation was performed, and no corrective action was taken. The repair facility has refused to address the condition of these parts, and the insurer has refused to authorize further inspection. Additionally, there are discrepancies between the insurance estimate and the final repair invoice, raising concerns about whether the documented work matches what was actually performed, including work involving structural components such as the cradle/subframe. I believe this vehicle may be unsafe to operate and that the repair may have introduced or failed to correct conditions that pose a risk to driver safety. I request that this matter be reviewed as a potential safety defect related to post-collision repair. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I own a 2021 Jeep Grand Cherokee Trailhawk which we purchased new. On Dec 30, 2025 we were driving home and received a service suspension message on the dash. We took it to our mechanic immediately and they diagnosed it and replaced the left front ride sensor. $380.88 In Jan 21,2026 the ride height message was back. They removed and replaced the air pump assembly with a new united. To remove & replace-suspension-rear suspension-ride control compressor, R&R $2,026.31. Feb 26, 2026 Took back to Lithia Dealership . Stability Control light was on and Traction control light are on check on advise. Changed out Module Transfer Case $1,013.33. Upon further research found out other Jeep owners had the same problem with the air suspension system. I feel this should be looked into.

Vehicle code: C1562-98 AIR PUMP CONTROL - air suspension compressor is overheating or there's a problem with the control system, leading to issues with adjusting the vehicle's height. With further inspection he found a leak in the air bag fittings. Vehicle Power Control Module has caused vehicle to shutoff while driving on the highway. Air suspension and electrical issues continued after 60 days of attempted repairs.

Over the past year, I've noticed a suspension-related squeak - increasing in frequency - coming from the rear of my 2021 Jeep Grand Cherokee Limited vehicle. I brought this to the attention of the Jeep dealer service dept where I purchased the vehicle, as well as to another independent auto repair shop, and both indicated they could not find anything wrong. Today, I saw news on the internet of the Jeep Grand Cherokee Limited "rear coil spring" issue as described in this Safety Recall report [XXX] and now believe the noise I've been hearing may be related to this recall.

Almost lost control of vehicle but was able to pull off onto grass median. My wife and 5 year old son were in car with me. Could have been a catastrophe lucky traveling at slow speed(just came off highway). Towed to Dealer. Huntington Jeep dealer on Jericho Tpke 11743 said looks like damaged caused by hitting a pot hole.

Unknown. Suspension issue/s cause car to jitter and vibrate (unsettled washboard-like ride quality) on the road. Suspension is standard-- not air suspension. Noticeable vibrations/jittering at speeds over 35mph. Makes steering difficult. Makes driving exhausting, as every undulation is transferred into the cabin. Issue has not yet been inspected by dealer or manufacturer. No warning lights--- but it is a suspension system, so a warning light is not likely. This is a brand new vehicle. It should not be exhibiting these problems. I have tested the same model from several different years and none exhibit this ride characteristic, it is just my vehicle.
